Description

Technical Field

[0001] The utility model belongs to the technical field of tool box storage equipment, and particularly relates to a plug-in locking mechanism for a push rod of a tool box cart. Background Art

[0002] Tool boxes containing hardware tools are often stacked and placed on a cart for easy movement or transportation, using a push-pull rod to pull the tool boxes. This greatly saves manpower. However, when the stacked tool boxes are removed, the height of the push-pull rod takes up space, making the cart difficult to place. Therefore, in actual production, the push-pull rod of the cart is usually designed to be removable. When the cart is being pushed, the push-pull rod is installed on the cart; when not being pushed, the rod is removed to save storage space.

[0003] However, the detachable structure of the tool box cart currently on the market is usually installed in a buckle-type manner. The buckle can easily be hit or caught by other objects, causing the buckle to loosen and affecting the installation stability of the push-pull rod. Utility Model Content

[0026] The plug-in locking mechanism of the push-pull rod of the tool box cart of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, a structural schematic diagram of the plug-in locking mechanism of the push and pull rods of the tool box cart is given.

[0028] The plug-in locking mechanism of the push-pull rod of the toolbox cart includes a base 1, a push-pull rod fixing groove 2 is provided on the outside of the base 1, and a plug-in locking mechanism 3 is installed on the outside of the push-pull rod fixing groove 2. The push-pull rod 4 of the toolbox cart can be removably inserted into the push-pull rod fixing groove 2 and locked or unlocked by the plug-in locking mechanism 3.

[0029] The number of push-pull rod fixing slots 2 is the same as the number of push-pull rods 4. In this embodiment, there are two push-pull rod fixing slots 2, which are located on the left and right sides of the same outer side of the base 1 respectively; the number of push-pull rods 4 is two and they are arranged in parallel, and a connecting rod 5 is provided vertically connected between the two push-pull rods 4. The connecting rod 5 can be conveniently held by the user to push the toolbox cart.

[0030] In other preferred embodiments, the number of the push-pull rod fixing slot 2 and the push-pull rod 4 are both 1, and a connecting rod 5 is provided vertically connected to the push-pull rod 4. The position of the push-pull rod fixing slot 2 can be arranged according to actual needs for easy use.

[0031] The plug-and-lock mechanism 3 includes a sliding component 6 and a latch 7 . The latch 7 is fixed inside the sliding component 6 .

[0032] A sliding groove 8 is provided on the outer edge of the push-pull rod fixing groove 2 in a direction perpendicular to the push-pull rod fixing groove 2 , and the sliding component 6 is slidably installed in the sliding groove 8 .

[0033] A locking hole 9 is provided on the outer wall of the push-pull rod fixing slot 2, and a latch 7 is positioned correspondingly with the locking hole 9. A square hole 10 is also provided on the push-pull rod 4. After the sliding member 6 drives the latch 7 through the locking hole 9, the latch 7 is inserted into or removed from the square hole 10 to lock or unlock the push-pull rod 4. In the locked state, the push-pull rod 4 can be pushed, thereby moving the toolbox cart. In the unlocked state, the push-pull rod 4 can be removed from the base 1, lowering the height of the toolbox cart and saving storage space.

[0034] To secure the plug-in locking mechanism 3, it also includes a stopper 11 and a spring 12. A mounting slot 13 is defined on the outer edge of the push-pull rod fixing slot 2, outside the locking hole 9. The stopper 11 and spring 12 are positioned within the mounting slot 13. One end of the spring 12 is fixedly connected to the inner sidewall of the mounting slot 13, and the other end is fixedly connected to the stopper 11. Multiple sets of parallel grooves 14 are defined on the outer sidewall of the latch 7, connected by inclined surfaces. A protrusion 15 is defined on the end of the stopper 11 away from the spring 12, with the grooves 14 and protrusion 15 aligning with each other. Both the stopper 11 and the spring 12 are provided in two sets, one on each side of the latch 7.

[0035] In addition, in order to facilitate the pushing of the tool box cart, rollers 16 are provided under the base 1 .

[0036] The working principle of the plug-in locking mechanism of the tool box cart push and pull rod of the utility model is:

[0037] 1. When the push-pull rod 4 is locked:

[0038] Insert the push-pull rod 4 into the push-pull rod fixing groove 2, and make the position of the square hole 10 correspond to the locking hole 9, push the sliding part 6 toward the inside of the base 1, and the sliding part 6 slides in the sliding groove 8, driving the latch 7 to move toward the inside of the push-pull rod 4, and the latch 7 is inserted into the square hole 10; in the process of the latch 7 moving toward the inside of the push-pull rod 4, the inclined surfaces between the multiple groups of grooves 14 will squeeze the spring 12 to compress, driving the limiter 11 away from the latch 7, providing space for the displacement of the latch 7; when the latch 7 moves into place inside the push-pull rod 4, the protrusion 15 at the end of the limiter 11 is stuck in the groove 14, the spring 12 recovers, and the limiter 11 clamps the latch 7 to limit the position of the latch 7, preventing the latch 7 from slipping, ensuring that the position of the latch 7 in the square hole 10 is fixed, and the locking step of the push-pull rod 4 is completed.

[0039] 2. When the push-pull rod 4 is unlocked:

[0040] Pull the sliding part 6 toward the outside of the sliding groove 8, driving the pin 7 to move toward the outside of the push-pull rod 4, and the pin 7 moves out of the square hole 10; in the process of the pin 7 moving toward the outside of the push-pull rod 4, the inclined surfaces between the multiple groups of grooves 14 will squeeze the spring 12 to compress, driving the limit member 11 away from the pin 7, providing space for the displacement of the pin 7; when the pin 7 moves to the outside of the push-pull rod 4, the protrusion 15 at the end of the limit member 11 will be stuck in the groove 14, the spring 12 recovers, and the limit member 11 clamps the pin 7 to limit the position of the pin 7, preventing the pin 7 from slipping and avoiding the falling off of the plug-in locking mechanism 3; at this time, the pin 7 is completely removed from the square hole 10, the push-pull rod 4 is pulled upward, and the push-pull rod 4 is taken out of the push-pull rod fixing groove 2, thereby completing the unlocking step of the push-pull rod 4.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
