Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a drawer mechanism with a self-locking structure comprises a cabinet body 1, a drawer 2 is movably connected inside the cabinet body 1, a handle 3 is fixedly connected to the front of the drawer 2, a pressing rod 4 is movably connected to the right side of the cabinet body 1, two limiting grooves 5 are formed in the bottom of the drawer 2, the two limiting grooves 5 are arranged at proper positions of the front end and the rear end of the bottom of the drawer 2, a threaded rod 6 is fixedly connected to the left side of the pressing rod 4, a first spring 7 is fixedly connected to the right side of the threaded rod 6, a fixed block 8 is fixedly connected to the left side of the first spring 7, two ends of the first spring 7 are respectively fixedly connected to the right side of the threaded rod 6 and the left side of the fixed block 8, the fixed block 8 is fixedly connected to the inside of the cabinet body 1, a gear 9 is connected to the outer side of the threaded rod, the outer side of the threaded rod 6 is provided with threads matched with the inside of the gear 9, the right side of the gear 9 is engaged and connected with a lifting rod 10, the left side of the lifting rod 10 is fixedly connected with at least six teeth, the teeth are engaged and connected with the gear 9, the top of the lifting rod 10 is fixedly connected with a limiting head 11, when the drawer 2 is pulled open or closed, two limiting grooves 5 are both arranged right above the limiting head 11, the diameter of the inside of each limiting groove 5 is larger than that of the limiting head 11, the bottom of the lifting rod 10 is fixedly connected with a second spring 12, one side of the second spring 12, which is far away from the lifting rod 10, is fixedly connected with a groove 13, the groove 13 is arranged at the bottom of the inside of the cabinet body 1, the lifting rod 10 is fixedly connected with the bottom of the groove 13 through the second spring 12, the inside of the cabinet body 1 is fixedly connected with four fixing rods 14, and is fixedly connected with the inside of the cabinet body 1, the number of the round balls 15 is four, and the four round balls 15 are respectively connected to two sides of the gear 9 in a sliding manner.

The working principle is that the handle 3 is pulled, the handle 3 is fixedly connected to the front face of the drawer 2, the drawer 2 is movably connected to the inside of the cabinet body 1, the drawer 2 can move towards the outside of the cabinet body 1 at the moment, the ascending rod 10 is fixedly connected with the bottom of the groove 13 through the second spring 12, the groove 13 is formed in the bottom of the inside of the cabinet body 1, the second spring 12 can always give upward movement force to the ascending rod 10, the limiting head 11 is fixedly connected to the top of the ascending rod 10, the limiting head 11 can always bear upward force, the two limiting grooves 5 are both located right above the limiting head 11 when the drawer 2 is pulled open or closed, the diameter of the inside of each limiting groove 5 is larger than that of the limiting head 11, therefore, the limiting heads 11 can move into the limiting grooves 5, the limiting grooves 5 are formed in the bottom of the drawer 2, and the drawer 2 can not be clamped to move, thereby achieving the effect that the drawer 2 has a locking function after being closed or opened. When the drawer 2 needs to be closed, the pressing rod 4 is pressed to the left side, because the left side of the pressing rod 4 is fixedly connected with the threaded rod 6, the threaded rod 6 also moves to the left side, because the outer side of the threaded rod 6 is in threaded connection with the gear 9, the outer side of the threaded rod 6 is provided with the thread matched with the inner part of the gear 9, when the threaded rod 6 moves to the left side, the gear 9 rotates clockwise, at the same time, the gear 9 rotates clockwise under the action of the threaded rod 6, because the four round balls 15 are respectively in sliding connection with two sides of the gear 9, at the same time, the gear 9 can only self-transmit clockwise around the threaded rod 6 under the driving of the threaded rod 6, and because the left side of the lifting rod 10 is fixedly connected with not less than six teeth, and the teeth are in meshed connection with the gear 9, at the same time, the gear 9 drives the lifting rod 10 to move, so that the lifting rod 10 moves downwards, and, therefore, the ascending rod 10 drives the limiting head 11 to move downwards, so that the limiting head 11 moves out of the limiting groove 5, and the effect that the drawer 2 can be normally used is achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
