Referring to fig. 1-4, a trailer structure for road management comprises a universal wheel 1, a first bearing 2 is fixedly connected to the top surface of the universal wheel 1, the middle portion of the first bearing 2 is fixedly sleeved at the bottom end of a threaded rod 3, the lower portion of the threaded rod 3 is in threaded sleeve connection with the middle portion of a spiral ring 4, the top end of the threaded rod 3 is fixedly connected with a fixed ring 5, the middle portion of the fixed ring 5 is movably sleeved with a pry bar 6 extending outward, the inner cavity of the pry bar 6 is movably sleeved with a first telescopic rod 7 extending leftward, one end of the first telescopic rod 7 located in the inner cavity of the pry bar 6 is in threaded sleeve connection with a fastening knob 8, the number of the spiral rings 4 is two, the two spiral rings 4 are respectively fixedly sleeved at the middle portions of the side surfaces of a first table top 9 and a second table top 10, rubber blocks 11 are respectively fixedly connected to the first table top 9 and the right side and the left, and the bottom surface fixed connection of second mesa 10 has dead lever 13 to stretching out to the left side, dead lever 13 activity cup joints the inner chamber at fixed pipe 12, evenly distributed's circular slot 14 is seted up on the front of fixed pipe 12, right side circular slot 14 joint has latch device 15, latch device 15 fixed connection is at the left end of dead lever 13, middle part fixed connection on second mesa 10 right side has connecting block 16, the one end joint that second mesa 10 was kept away from to connecting block 16 has pivot 17, the middle part fixed connection of pivot 17 has the pipe 18 of prizing of stretching out to both sides, the inner chamber activity of the pipe 18 left end of prizing has cup jointed telescopic link two 19, telescopic link two 19 fixed connection is on the top of transfer line 20, bearing two 21 is installed to the bottom of transfer line 20, the inner chamber of bearing two 21 is fixed to cup joint the sheet rubber 22 that.

Wherein, latch device 15 is including rectangular block 151, and the bottom surface fixed connection of rectangular block 151 inner chamber is in the one end of spring 152, and the other end fixed connection of spring 152 is at the middle part of locating plate 153 bottom surface, and the left and right sides of locating plate 153 fixedly connected with slider 154 respectively, and the spout has been seted up respectively to the left and right sides of rectangular block 151 inner chamber, and both sides slider 154 joint respectively in the spout, and the top surface fixedly connected with of locating plate 153 is the joint 155 that outwards stretches out. The spring 152 is mainly used for providing elasticity, two ends of the spring 152 are respectively connected with the bottom surface of the rectangular block 151 and the side surface of the positioning plate 153, and the rectangular block 151 is fixed, so the positioning plate 153 can be always ejected outwards by the elasticity of the spring 152, the sliding block 154 is matched with sliding grooves on two sides of the inner cavity of the rectangular block 151 for common use, so that the positioning plate 153 can only slide up and down along a certain track, the clamping head 155 can be prevented from being ejected to the outside of the rectangular block 151, and when the clamping head 155 is clamped in the circular groove 14, the first table top 9 and the second table top 10 can be fixed.

The universal wheels 1 are divided into two groups, the two groups of universal wheels 1 are respectively and fixedly connected to the bottom surfaces of the first table top 9 and the second table top 10, and the bottom surfaces of the two groups of universal wheels 1 are on the same horizontal plane. Through the design that adopts two sets of universal wheels 1 to the bottom surface of two sets of universal wheels 1 is on same horizontal plane, makes universal wheel 1 not only can provide the effort of activity for the device, can also ensure the stability of device self, and universal wheel 1 is this device can realize the important structural support of trailer operation.

The right side of the first table top 9 and the left side of the second table top 10 are respectively inclined, the inclined angle values of the two sides are equal, and the surface of the rubber block 11 is a smooth curved surface. When carrying out the trailer operation, need install the device in the both sides of wheel hub to promote the vehicle, be convenient for carry out the trailer operation after going on, through the design that adopts the slope respectively with the side of first mesa 9 and second mesa 10, cooperate the common use of block rubber 11 simultaneously, make first mesa 9 and second mesa 10 when jacking the vehicle, can not cause the damage to the tire, the frictional force between device and the tire has also been increased, avoid the condition that the activity appears in the vehicle.

The second bearing 21 is U-shaped, and the notch value in the middle of the second bearing 21 is smaller than the diameter value of the transmission rod 20. When the rubber sheet 22 and the road surface contact each other to realize the braking operation, the transmission rod 20 moves up and down in the middle of the connecting block 16, and the connecting block 16 is designed in a U shape, so that a moving space is left for the transmission rod 20, and the transmission rod 20 is prevented from rubbing against the connecting block 16 during movement.

The second telescopic rod 19 is composed of three rod bodies of bearings, the rod bodies are fixedly sleeved in the middle of the third bearing, the third bearing is fixedly connected above the right side of the transmission rod 20, and one end, located in the inner cavity of the prying pipe 18, of the second telescopic rod 19 is fixedly connected with a clamping block located outside the prying pipe 18. When the prying pipe 18 is lifted by the prying bar 6, the moving track of the prying pipe 18 is arc-shaped under the action of the rotating shaft 17, but the transmission rod 20 needs to vertically move up and down, and the telescopic rod 19 is sleeved in the prying pipe 18, so that the transmission rod 20 can move up and down by the rotation of the prying pipe 18.

The middle part of the front side of the pry bar 6 is provided with a strip-shaped groove, and the length value of the strip-shaped groove is equal to that of the first telescopic rod 7. The design of the positive strip groove of pinch bar 6 has left the space of activity for fastening knob 8 can slide along certain orbit, after fastening knob 8 is unscrewed, the length of telescopic link 7 can be adjusted, after telescopic link 7 is stretched, can reach the effect that increases the arm of force.

The working principle is as follows: when the lifting device is used, the first table top 9 and the second table top 10 are respectively placed on two sides of a tire, the clamping head 155 is pressed to the inner cavity of the rectangular block 151, the fixing rod 13 is sleeved in the inner cavity of the fixing pipe 12, when the clamping head 155 is outwards popped out of the circular groove 14, the positions of the first table top 9 and the second table top 10 can be fixed, the pry bar 6 is taken out, one end of the pry bar 6 is inserted into the middle of the fixing ring 5 and continuously rotates, the threaded rod 3 can synchronously rotate along with the pry bar 6, due to the threaded sleeved connection between the threaded rod 3 and the spiral ring 4, the first table top 9 can be continuously lifted upwards, then the second table top 10 is lifted according to the same method until obstacles on the road surface cannot influence the movement of a trailer, when the pry bar 6 is difficult to rotate, the fastening knob 8 can be unscrewed, and the first telescopic rod 7 can freely slide in the inner cavity of the pry bar 6, when a telescopic link 7 is outwards pulled out, can reach the effect that increases the arm of force, after the vehicle is tensile finishes, insert crow bar 6 to the pipe 18 of levering, later carry on the trailer operation can, when the out of control condition appears in the vehicle, stop the trailer operation immediately, and in time hand-held crow bar 6 upwards pulls, the effort of activity downwards can appear in this moment transfer line 20, make the sheet rubber 22 closely laminate with the road surface, thereby increased the frictional force between road surface and the trailer ware, force the device stop the activity.
