Description

Technical Field

[0001] The utility model belongs to the technical field of GCS cabinet drawers, and particularly relates to a toggle locking structure for GCS cabinet drawers. Background Art

[0002] The GCS cabinet is a low-voltage draw-out switch cabinet, which is designed and developed by a joint design team according to the requirements of industry authorities, power users and design units. It has high technical performance indicators, can meet the development needs of the power market, and can compete with existing imported products;

[0003] The GCS cabinet is widely used in power plants, petrochemical industries, metallurgy and other places. When the existing GCS cabinet is in use, when the drawer inside it is pulled close to the limit position, the speed reduction and buffering effects are poor, and collisions are likely to occur. Therefore, a toggle locking structure for GCS cabinet drawers is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a toggle locking structure for GCS cabinet drawers. Through the cooperation of the inclined plate, the first sliding rod and the tension spring, it can not only play a locking role, but also play a buffering and decelerating role, prevent the drawer from moving quickly and colliding, reduce vibration, improve the service life of equipment parts, and at the same time, when the drawer is quickly pulled out, it contacts the buffer rod and is buffered by the second spring, avoiding the drawer being pulled out of the electrical box and improving the safety of use, thus solving the existing technical problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A toggle locking structure for GCS cabinet drawers includes: a drawer and guide rails arranged on both sides of the drawer. Both sides of the drawer are fixed with support rods through bolts, and the two support rods are respectively slidably connected with the two guide rails. One end of each guide rail is fixedly connected with a positioning plate, and a clearance notch is arranged at the bottom of the positioning plate;

[0007] Locking mechanisms for fixing the drawer are arranged on both sides of the drawer. The locking mechanism includes a first sliding rod, the first sliding rod slidably penetrates through one side of the drawer, a second sliding rod is slidably connected to one side of the first sliding rod, one end of the second sliding rod is fixedly connected with an inclined plate arranged obliquely, a tension spring is fixedly connected between the second sliding rod and the first sliding rod, and a first spring is fixedly connected between the first sliding rod and the inner wall of one side of the drawer. Through the arrangement of an activatable inclined plate at one end of the first sliding rod, the cooperation of the inclined plate, the first sliding rod and the tension spring can not only play a locking role, but also play a buffering and decelerating role, prevent the drawer from moving quickly and colliding, reduce vibration, and improve the service life of equipment parts;

[0008] A driving mechanism, which is arranged in the drawer and used to drive the first sliding rod to move.

[0009] As a further solution of the present utility model, the driving mechanism includes two inclined holes and a driving plate. The two inclined holes are respectively arranged on one side of the two first sliding rods. The driving plate is arranged in the drawer. Two mounting seats are fixedly connected to one side of the driving plate. Rollers are rotatably connected in the two mounting seats. The two rollers are respectively used in cooperation with the two inclined holes. A pull rod is fixedly connected to one side of the driving plate.

[0010] As a further solution of the present utility model, the pull rod slides through the drawer and is fixedly connected with a pull plate.

[0011] As a further solution of the present utility model, a handle is fixedly connected to the outer wall of one side of the drawer, and the pull plate is located in the handle.

[0012] As a further solution of the present utility model, side plates are fixedly connected to the bottoms of the guide rails. Buffer rods penetrate through the side plates and are slidably connected to the side plates. Second springs are fixedly connected between the buffer rods and the side plates. Through the cooperation of the buffer rods and the second springs, when the drawer is quickly pulled out, it contacts the buffer rods and is buffered by the second springs, preventing the drawer from being pulled out of the electrical box and improving the safety of use.

[0013] As a further solution of the present utility model, a protective cover is fixedly connected to the inner wall of one side of the drawer. An avoidance groove penetrates through the top of the protective cover. Vertical plates are fixedly connected to the tops of the two first sliding rods, and the vertical plates are all located in the avoidance groove.

[0014] In this application, during use, the guide rail is fixed inside the electrical box by rivets or bolts. Then, the support rods are fixed on both sides of the drawer. After fixation, the support rods are inserted into the guide rail, and then the drawer is placed into the electrical box. After the drawer quickly enters the electrical box, first, the inclined plate arranged obliquely contacts the avoidance opening on the positioning plate, causing the first sliding rod to slide into the drawer. Subsequently, after the inclined plate disengages from the avoidance opening on the positioning plate, the first sliding rod moves to one side of the positioning plate, thus completing the locking of the drawer. At the same time of contact, the inclined plate cooperates with the tension spring, which can also play a role in buffering and decelerating, preventing the drawer from colliding during rapid movement, reducing vibration, and extending the service life of the equipment components. When it is necessary to pull out the drawer, pull the pull plate. The pull plate drives the driving plate to move through the pull rod. The driving plate drives the mounting seat and the roller to move in the inclined hole, and pushes the first sliding rod to move through the inclined hole, thus unlocking and enabling the drawer to be pulled out. When the drawer is quickly pulled out, it contacts the buffer rod and is buffered by the second spring, preventing the drawer from being pulled out of the electrical box and improving the safety of use. When it is necessary to take out the drawer again, pull the two vertical plates, and move the first sliding rod into the drawer through the vertical plates, thus enabling the drawer to be taken out for maintenance, which is convenient for people to use.

[0015] The embodiments of the present utility model have the following beneficial effects:

[0016] In the present utility model, through the setting of installing a movable inclined plate at one end of the first sliding rod, the cooperation of the inclined plate, the first sliding rod and the tension spring can not only play a locking role, but also play a role in buffering and decelerating, preventing the drawer from colliding during rapid movement, reducing vibration, and extending the service life of the equipment components;

[0017] In the present utility model, through the combined use of the buffer rod and the second spring, when the drawer is quickly pulled out, it contacts the buffer rod and is buffered by the second spring, preventing the drawer from being pulled out of the electrical box and improving the safety of use;

[0018] In the present utility model, through the cooperation of the inclined plate, the first sliding rod and the tension spring, it can not only play a locking role, but also play a role in buffering and decelerating, preventing the drawer from colliding during rapid movement, reducing vibration, and extending the service life of the equipment components. At the same time, when the drawer is quickly pulled out, it contacts the buffer rod and is buffered by the second spring, preventing the drawer from being pulled out of the electrical box and improving the safety of use.

[0019] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS
