Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a pet cage door lock, which comprises a cage body 1, a cage door 2, a lock shell 3, a bolt 4 and a lock cylinder 5, wherein the interior of the cage body 1 is hollow, and one end of the cage body is opened; the cage door 2 is arranged opposite to the opening end of the cage body 1, and one end of the cage door 2 is hinged with the cage body 1.

the other end of the lock shell 3, which is opposite to the cage door 2, is connected to the cage body 1, the outer wall of the lock shell 3 is inwards sunken to form a sliding groove, at least one first notch a is formed in the lock shell 3, and the first notch a is communicated with the sliding groove.

Preferably, the sliding groove is formed by inwards recessing one side of the lock shell 3 close to the cage body 1, and the sliding groove penetrates through the lock shell 3 along the length direction of the lock shell 3; the number of the first gaps a can be one, two, three and the like, preferably, the horizontal section of the lock shell 3 is U-shaped, the lock shell 3 is vertically and downwardly arranged on the cage body 1, and the number of the first gaps a is two.

The lock shell 3 is U-shaped in cross section, so that the lock shell 3 can be produced by bending and blanking a plate body, and the processing is convenient.

Spring bolt 4 is connected in cage door 2, spring bolt 4 with first breach a one-to-one sets up, and spring bolt 4 can be the body of rod, block etc. preferably, and spring bolt 4 is the columniform body of rod. When the latch tongue 4 is a cylindrical rod body, the cylindrical rod body is convenient to slide relative to the clamping portion 52.

The lock cylinder 5 comprises a lock cylinder body 51 and at least one clamping portion 52, the lock cylinder body 51 is slidably inserted into the sliding groove and can slide between a first position and a second position, the clamping portion 52 corresponds to the first notch a one to one, the clamping portion 52 is opposite to the first notch a, one end of the clamping portion 52 is connected to the lock cylinder body 51, the other end of the clamping portion is bent towards the direction close to the lock cylinder body 51, a clamping groove b is defined between the clamping portion 52 and the lock cylinder body 51, the inner wall of the clamping groove b is clamped to the lock tongue 4 and limits the lock tongue 4 to the clamping groove b in the first position, and the clamping groove b is far away from the lock tongue 4 in the second position.

Preferably, lock core body 51 is rectangular shape plate body, rectangular shape plate body is relative at least one second breach c has been seted up to first breach a, the quantity of first breach a, second breach c can be one, two, three etc, second breach c with first breach a one-to-one sets up, and the other end of joint portion 52 extends to in the second breach c, joint portion 52 with inject draw-in groove b between the inside of second breach c, draw-in groove b opening sets up down, and the other end of joint portion 52 is crooked downwards.

Further preferably, the second notch c is a right trapezoid, the other end of the clamping portion 52 is opposite to the inclined side of the right trapezoid, and the number of the first notch a and the second notch c is two.

Because the second notch c is a right trapezoid, when the lock cylinder body 51 and the clamping portion 52 are pushed to move upwards, the oblique side of the right trapezoid of the second notch c can push the bolt 4 to move in the direction away from the lock cylinder body 51.

Preferably, the number of the clamping portions 52 may be one, two, three, or the like, the clamping portions 52 are arranged in the sliding groove, each clamping portion 52 includes a first abutting surface 521 and a second abutting surface 522, the first abutting surface 521 is arranged vertically downward, the first abutting surface 521 is a surface on which the other end of the clamping portion 52 abuts against the bolt 4, the second abutting surface 522 is a surface on which the clamping portion 52 is far away from the cage body 1, the second abutting surface 522 may be an inclined surface or an arc surface, when the first abutting surface 521 is an inclined surface, the size of the horizontal cross section of the clamping portion 52 is gradually increased along an upward direction, when the first abutting surface 521 is an arc surface, the first abutting surface 521 is an outwardly convex arc surface, and the curvature of the arc surface is gradually decreased along a direction close to the tail end of the clamping portion 52.

More preferably, the number of the snap portions 52 is two.

preferably, the first position is a position where the latch tongue 4 is tightly latched by the latching portion 52.

preferably, a through-hole has been seted up to lock shell 3, the through-hole runs through lock shell 3 and is linked together with lock shell 3, and lock core body 51 is relative a bar hole has been seted up to the through-hole, the bar hole is followed the direction setting of spout, pet cage lock still includes a locating part 6, and locating part 6 warp through-hole, bar hole pass lock shell 3, lock core body 51, and locating part 6 is connected in lock shell 3.

Further preferably, the position limiting member 6 includes a first screw 61 and a first nut 62, a threaded end of the first screw 61 passes through the lock case 3 and the lock cylinder body 51 through the through hole and the strip-shaped hole, the first nut 62 is in threaded connection with the first screw 61 and is connected to one end of the first screw 61 far away from the head, and the first nut 62 abuts against the lock case 3.

Through setting up bar hole, first screw 61, first nut 62, can restrict the maximum motion position of lock core body 51, joint portion 52 relatively, prevent that lock core body 51, joint portion 52 from following roll-off in the spout.

Preferably, the sliding groove penetrates through the lock case 3 along the guide direction, and the door lock further comprises a lock pin 7, wherein the lock pin 7 is arranged outside the lock case 3 and detachably connected to the lock cylinder body 51.

further preferably, one end of the lock cylinder body 51 is provided with a second through hole, and the lock pin 7 is inserted into the second through hole to limit the sliding of the lock cylinder body 51.

The pet cage can vibrate in the transportation process, the bumpy lock cylinder body 51 can be prevented from sliding upwards relative to the sliding groove by arranging the second through hole and the lock pin 7, the lock bolt 4 can be always fixed in the clamping groove b by limiting the movement of the lock cylinder body 51 and the clamping portion 52, the cage door 2 can be prevented from being automatically opened, and when the cage door 2 needs to be opened, the lock pin 7 can be pulled down from the lock cylinder body 51.

preferably, the second position is that the inner wall of the upper end of the strip-shaped hole abuts against the first screw 61.

when the cage door 2 is opened: the lock cylinder body 51 is pushed upwards, so that the clamping portion 52 moves upwards until the bolt 4 is separated from the clamping groove b, and then the bolt 4 and the cage door 2 rotate relative to the cage body 1, so that a pet can conveniently come out of the cage body 1.

When closing cage door 2, with spring bolt 4, cage door 2 rotates along the direction that is close to joint portion 52, when spring bolt 4 butt in corresponding joint portion 52, because the butt face is inclined plane or arcwall face, the in-process of 4 butt joint portions 52 of spring bolt, can promote lock core body 51, joint portion 52 upward movement, until spring bolt 4 is located between joint portion 52 and the lock core body 51, at this moment, lock core body 51, joint portion 52 loses the power that upwards promotes, lock core body 51, joint portion 52 drops downwards under the effect of gravity, make the inner wall joint until draw-in groove b in spring bolt 4, lock core body 51 this moment, joint portion 52 can't continue the lapse, the fixed completion of cage door 2, the in-process of fixed cage door 2 only need promote cage door 2 can, and is simple and convenient.
