AI Technical Summary
The existing self-closing angle guide rails are prone to slide out during the drawer moving, resulting in inconvenient moving.
A new type of guide rail structure is designed, including an outer rail and an inner rail, with a hook on the outer rail and an elastic buffer assembly on the inner rail. When the drawer is closed, the pull hook is connected to the elastic buffer assembly. The outer rail drives the pull hook under the action of external force to push the elastic buffer assembly to move and deform; cancel the external force, and the elastic buffer assembly resumes deformation and drives the pull hook and the outer rail to move in the opposite direction until The pull hook removes the elastic buffer assembly to keep the drawer open.
Effectively prevent the drawer from sliding out during the moving process, ensuring the stability and convenient operation of the drawer, and at the same time buffering the impact force between the drawer and the cabinet body to protect parts.

Abstract
Description
Technical Field
[0001] The utility model particularly relates to a novel guide rail structure. Background Art
[0002] At present, drawers of various office desks are equipped with freely sliding drawer rails. Existing drawers generally use self-closing angle rails. A section of the rail is slightly inclined downward at the rear end of the fixed rail, so that the front roller of the sliding rail installed on the drawer automatically slides down under the action of its own weight when it moves to the inclined section, thereby ensuring that the drawer is completely closed. However, this self-closing angle rail has the following problems during use: due to the small bending angle of the rail, when the drawer is slightly tilted outward, it may slide out and fall to the ground. Especially when moving the cabinet, the drawer is often easy to slide out under the action of its own weight, causing inconvenience in moving. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a novel guide rail structure.

[0005] A novel guide rail structure comprises an outer rail for connecting a drawer and an inner rail for connecting a cabinet, wherein the outer rail is slidably arranged on the inner rail, a pull hook is arranged on the outer rail, and an elastic buffer component is arranged on the inner rail; when the drawer is in a closed state, the pull hook is connected to the elastic buffer component, and the outer rail drives the pull hook to push the elastic buffer component to move and deform it under the action of an external force; when the external force is removed, the elastic buffer component restores its deformation and drives the pull hook and the outer rail to move in opposite directions until the pull hook escapes from the elastic buffer component to open the drawer.
[0006] Preferably, the elastic buffer assembly includes an elastic member arranged on the inner rail and a connecting seat arranged on the elastic member, a rotating block is rotatably arranged on the connecting seat, and one end of the pull hook is assembled on the rotating block.
[0007] Preferably, the elastic member is a spring.

[0010] Preferably, a stopper is provided on the connecting seat, and a positioning groove is provided on the outer shell. When the connecting seat drives the stopper to be limited in the positioning groove, the connecting seat stops moving.
[0011] Preferably, a clamping block for clamping the outer shell is provided on the inner rail.
[0012] Preferably, a fixing block for connecting one end of the elastic member is provided on the housing.
[0013] The beneficial effects of the utility model are:

[0029] Furthermore, the elastic buffer assembly includes an elastic member 41 arranged on the inner rail 2 and a connecting seat 42 arranged on the elastic member 41 , a rotating block 43 is rotatably arranged on the connecting seat 42 , and one end of the pull hook 3 is assembled on the rotating block 43 .
[0030] Furthermore, the elastic member 41 is a spring.
[0031] Furthermore, the rotating block 43 is provided with an opening 431 for the hook 3 to be inserted into.
[0032] Furthermore, a shell 5 is provided on the inner rail 2 , a movable groove 6 is provided on the shell 5 , and the elastic buffer component is located in the movable groove 6 with one side extending out of the movable groove 6 .

[0035] Furthermore, a fixing block 22 for connecting one end of the elastic member 41 is disposed on the housing 5 .
[0036] The working principle of the utility model is:
[0037] The outer rail 1 is used to connect the drawer, and the inner rail 2 is used for the cabinet. The inner rail 2 can be connected and fixed in the cabinet by fasteners such as bolts. Figure 2 As shown, guide rail structures are generally provided on both sides of the drawer. In order to better illustrate the design principle of the present application, the initial state is defined as the drawer being in a closed state, such as Figure 1 As shown, when the drawer needs to be opened, the drawer is first pushed inward (inward means pushing it toward the inside of the cabinet). Since the drawer is connected to the outer rail 1, the outer rail 1 will slide relative to the inner rail 2 under the action of external force, and the hook 3 on the outer rail 1 is connected to the rotating block 43, so at this time the rotating block 43 and the connecting seat 42 will move inward synchronously, and a spring is provided between the connecting seat 42 and the fixed seat, so the connecting seat 42 will pull the spring to deform during the movement, and when the stopper on the connecting seat 42 is deformed, the connecting seat 42 will be opened. When the member 7 is limited in the positioning groove 8 on the shell 5, the connecting seat 42 stops moving; the force on the drawer is cancelled, and the spring recovers its deformation, driving the connecting seat 42, the rotating block 43, the hook 3, and the outer rail 1 to move outside the cabinet. When the spring is reset to the initial state, the connecting seat 42 stops moving, but the hook 3 and the outer rail 1 will still move forward (i.e., move toward the outside of the cabinet), and the hook 3 drives the rotating block 43 to rotate, and finally the hook 3 is disengaged from the rotating block 43, and the outer rail 1 pulls the drawer to open the drawer. Figure 7 shown.
[0038] When the drawer needs to be switched from the open state to the closed state, it is only necessary to push the drawer inwards, and the drawer drives the outer rail 1 to slide relative to the inner rail 2. One end of the hook 3 on the outer rail 1 first moves into the opening 431 of the rotating block 43. As the outer rail 1 continues to move, the hook 3 drives the rotating block 43 to rotate relative to the connecting seat 42. When the stopper 7 on the connecting seat 42 is limited in the positioning groove 8, the rotating block 43 rotates to the initial state (the initial state of the rotating block is shown in FIG. 1 ). Figure 1), the drawer is in the closed position.
[0039] On the basis of the above technical solution, the outer shell 5 can be fixed on the inner rail 2 by means of a clamping block (21).
[0040] The novel guide rail structure of the present application is coordinated with structures such as an elastic buffer assembly. When the cabinet is moved, the pull hook is connected to the elastic buffer assembly, which can effectively prevent the outer rail from sliding relative to the inner rail under the action of moving, thereby preventing the drawer from sliding out of the cabinet. In addition, when the drawer is pushed inward, the elastic buffer assembly has a buffering effect on the drawer, buffering the impact force between the drawer and the cabinet, and preventing the impact force from causing damage to components.
[0041] As Example 1, the drawer of the present application can be Figure 1 The handle shown allows the drawer to be detachably mounted on the outer rail (the drawer can also be fixed to the outer rail by other connection methods). Since the installation method of the handle is a mature means in the technical field and is not the main design concept of this application, its working principle will not be described in detail in this article.
[0042] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
