Description

Technical Field

[0001] The utility model relates to the field of slide rails, in particular to a slide rail locking safety protection structure. Background Art

[0002] A slide rail, also known as a guide rail or a slideway, refers to a hardware connecting component fixed on the cabinet body of furniture for the drawer or cabinet board of the furniture to move in and out. The application of slide rails is the most common in the furniture field, especially in the connection of wooden and steel drawers such as cabinets, furniture, filing cabinets, and bathroom cabinets. In the field of mechanical manufacturing, as an important mechanical basic part, linear slide rails are widely used in various machine tools, machining centers, robots and other equipment.

[0003] Generally, a slide rail includes an inner rail and an outer rail, and the two can slide relative to each other. At present, the slide rail mainly uses the attraction of magnets installed on the inner rail and the outer rail to complete locking. However, after long-term use, the magnets age and the attraction decreases, which easily causes the inner rail and the outer rail to separate easily.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model discloses a slide rail locking safety protection structure.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A slide rail locking safety protection structure includes an inner rail, a middle rail and an outer rail that are slidably matched. An activity bar is slidably connected to the inner rail, and an unlocking block is rotatably connected to the inner rail. The activity bar and the unlocking block are connected. An inner and outer locking structure is provided at the end of the outer rail, and a hook is provided in the inner and outer locking structure. When the slide rail is locked, the unlocking block and the hook are clamped.

[0008] Further, a first rivet is provided between the unlocking block and the inner rail, and the unlocking block rotates around the first rivet as an axis.

[0009] Further, a second rivet is provided on the unlocking block, and a kidney-shaped hole is formed on the activity bar, and one end of the second rivet is located in the kidney-shaped hole.

[0010] Further, a second rivet is provided on the unlocking block, and a kidney-shaped hole is formed on the activity bar, and one end of the second rivet is located in the kidney-shaped hole.

[0011] Further, a first bent wall is provided on the unlocking block. When the slide rail is locked, the first bent wall and the hook are clamped.

[0012] Further, a second bent wall is provided on the unlocking block, and the second bent wall is on the side opposite to the first bent wall.

In order to make the objectives, features and advantages of the present utility model more obvious and understandable, please refer to the accompanying drawings. It should be noted that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present utility model.

[0026] A slide rail locking safety protection structure, as Figure 1 shown, includes an inner rail 1, a middle rail 2 and an outer rail 3 that are slidably engaged. The inner rail 1 is slidably disposed in the middle rail 2, and the middle rail 2 is slidably disposed in the outer rail 3.

[0027] As Figure 1 shown, a movable bar 11 is slidably connected to the inner rail 1. The movable bar 11 is arranged along the length direction of the inner rail 1, and one end of the movable bar 11 extends out of the end of the inner rail 1. A waist-shaped hole is formed in the movable bar 11, and the waist-shaped hole is arranged along the length direction of the movable bar 11. A tension spring 111 is disposed between the movable bar 11 and the inner rail 1. The tension spring 111 is arranged along the length direction of the inner rail 1, and the elastic return of the tension spring 111 drives the movable bar 11 to reset.

[0028] As Figure 1 shown, a rivet one 123 is disposed between the lock block and the inner rail 1, and the unlocking block 12 rotates about the rivet one 123 as an axis. A rivet two 124 is disposed on the unlocking block 12, and one end of the rivet two 124 is located in the waist-shaped hole. When the movable bar 11 moves, the rivet two 124 is driven to move through the waist-shaped hole, thereby driving the unlocking block 12 to rotate about the rivet one 123.

[0029] As Figure 2 and Figure 3 shown, a bent wall one 121 and a bent wall two 122 are disposed on the unlocking block 12, and the bent wall one 121 and the bent wall two 122 are bent toward the same side. As Figure 3 shown, when the unlocking block 12 is in the initial state, the bent wall two 122 abuts against the inner wall of the inner rail 1, playing a role in restricting the unlocking block 12 and preventing the rotation range of the unlocking block 12 from exceeding the designed range.

[0030] As Figure 3As shown in the figure, a hook 311 is provided in the internal and external locking structure 31. The hook 311 is set to be arc-shaped and bends inwardly into the inner part of the outer rail 3. A space for accommodating the first bent wall 121 is formed between the hook 311 and the internal and external locking structure 31. When the slide rail is locked, the first bent wall 121 and the hook 311 are engaged and cooperate with each other, and the two are mutually restricted to complete the locking of the inner rail 1 and the outer rail 3.

[0031] Specific working process:

[0032] Initially, the slide rail is in the default closed state. When it is necessary to open the slide rail, press the movable bar 11. The kidney-shaped hole 112 of the movable bar 11 drives the second rivet 124 to move inward, thereby driving the unlocking block 12 to rotate around the first rivet 123. The first bent wall 121 of the unlocking block 12 disengages from the hook 311 to complete the unlocking. The slide rail can be pulled outwards, and the inner rail 1 and the middle rail 2 move horizontally outwards along the length direction of the slide rail. When closing the slide rail, the inner rail 1 and the middle rail 2 move together in the closing direction. The unlocking block 12 contacts the hook 311, the unlocking block 12 rotates, and the first bent wall 121 is snapped onto the hook 311. The movable bar 11 is reset to the initial state of the slide rail under the action of the tension spring 111, and the slide rail is in the locked state.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0034] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
