Description

Technical Field

[0001] The utility model belongs to the technical field of slide rail tail supports, and particularly relates to a metal tail support. Background Art

[0002] For a general slide rail drawer, an American-style three-section hidden rail can be installed to realize the free pulling process of the drawer. When installing the American-style three-section hidden rail, a metal tail support needs to be inserted into the clamping groove at the tail end of the hidden rail to realize the installation and positioning of the hidden rail. For the existing metal tail support, it is usually a right-angled plate-like structure, and its installation and positioning are realized by inserting one end of it into the hidden rail. However, the following problems will occur: 1. There will be a large resistance when inserting the metal tail support into the clamping groove on the slide rail, and it is not easy to install; 2. After the metal tail support is inserted into the clamping groove, a large gap is generated between the metal tail support and the slide rail, resulting in a shaking situation. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a metal tail support to solve the problems in the above background art.

[0004] The utility model provides the following technical solutions. A metal tail support includes a plugging board and a fixing board fixed on one side of the plugging board. The fixing board and the plugging board are arranged at a right angle. The plugging board is respectively provided with symmetrically arranged first through grooves and symmetrically arranged second through grooves. The first through grooves are arranged on the side of the second through grooves away from the fixing board;

[0005] Clamping boards are symmetrically arranged on the sides of the two first through grooves close to each other. The clamping boards extend upward along the direction perpendicular to the upper surface of the plugging board, and the ends of the clamping boards away from the plugging board are inclined outward, so that a first plugging gap is formed between the clamping boards and the first through grooves;

[0006] Elastic protrusions are arranged in the second through grooves. The height of the elastic protrusions increases along the direction from both ends to the middle of the elastic protrusions, and the height at the middle position of the elastic protrusions is higher than the upper surface of the plugging board.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0022] In the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0023] In one embodiment of the present utility model, as Figure 1 、 2 shown, a metal tailstock includes a plug-in board 1 and a fixing board 2 fixed to one side of the plug-in board 1. The fixing board 2 is disposed at a right angle to the plug-in board 1. The plug-in board 1 is respectively provided with symmetrically arranged first through grooves 6 and symmetrically arranged second through grooves 8. The first through grooves 6 are arranged on the side of the second through grooves 8 away from the fixing board 2;

[0024] Specifically, in this embodiment, the plug-in board 1 and the fixing board 2 are fixedly arranged and are at a right angle to each other, thereby forming a right-angled plate-like structure. At the same time, there are two first through grooves 6 and two second through grooves 8 on the plug-in board 1. The second through grooves 8 are arranged on the side of the first through grooves 6 away from the fixing board 2.

[0025] On the side where the two first through grooves 6 are close to each other, clamping plates 7 are symmetrically arranged. The clamping plates 7 extend upward in a direction perpendicular to the upper surface of the plug-in board 1, and the ends of the clamping plates 7 away from the plug-in board 1 are inclined outward, so as to form a first plugging gap between the clamping plates 7 and the first through grooves 6;

[0026] Specifically, the clamping plate 7 extends upward along the direction perpendicular to the upper surface of the plugging plate 1. After extending to a certain length, the clamping plate 7 is inclined outward away from the plugging plate 1. Here, the outside specifically refers to the direction extending toward the two side edges of the plugging plate 1. In this way, a clamping plate 7 with a right-angled structure can be obtained, and there is a first plugging gap between the upper end of the clamping plate 7 and the upper surface of the plugging plate 1. When inserting the metal tail support into the track end of the hidden track, the track can be correspondingly inserted into the first plugging gap, and the clamping plate 7 is used for positioning and guiding it. At the same time, during installation, the cooperation between the track and the first plugging gap can improve the installation efficiency of the metal tail support, which is convenient for installation.

[0027] An elastic protrusion 9 is provided in the second through groove 8. Along the direction from both ends to the middle of the elastic protrusion 9, the height of the elastic protrusion 9 increases, and the height at the middle position of the elastic protrusion 9 is higher than the upper surface of the plugging plate 1.

[0028] Specifically, the elastic protrusion 9 itself has a certain elasticity, and its overall structure is low on both sides and high in the middle. Moreover, the height of the highest position in the middle of the elastic protrusion 9 is higher than the upper surface of the plugging plate 1. In this way, when the metal tail support is inserted into the track, under the elastic force of the elastic protrusion 9, the elastic protrusion 9 can abut against the track to fill the gap between the metal tail support and the track, avoiding the situation of shaking.

[0029] It should be noted that since the elastic protrusion 9 itself has a certain elasticity, the elastic protrusion 9 will bring a certain resistance to the installation of the metal tail support. However, since the clamping plate 7 is arranged on the front side of the elastic protrusion 9, when installing the metal tail support, the clamping plate 7 first contacts the track and the track is inserted into the first plugging gap, and initial limit is carried out through the clamping plate 7 to reduce the installation resistance brought by the elastic protrusion 9 and reduce the installation difficulty.

[0030] In this embodiment, a plurality of uniformly distributed mounting holes 4 are provided on the fixing plate 2.

[0031] Specifically, the mounting holes 4 can be used to install screws, and the fixing plate 2 is fixed through the screws and the mounting holes 4 to improve the stability of the metal tail support.

[0032] In this embodiment, a plurality of uniformly distributed mounting grooves 3 are provided on the fixing plate 2, and the mounting grooves 3 are circular-rectangular.

[0033] Specifically, the mounting groove 3 has a certain length, and its overall structure is rectangular with arc-shaped structures at both ends. Therefore, the position of the screw on the mounting groove 3 can be adjusted according to the actual installation position to be applicable to the installation of the fixing plate 2 in different situations.

[0034] In this embodiment, several reinforcing protrusions 5 are provided at the connection position between the plug-in board 1 and the fixed board 2;

[0035] Specifically, the reinforcing protrusions 5 can be used to enhance the overall strength and stability of the metal tail plate.

[0036] In this embodiment, there is a clearance between the elastic protrusion 9 and the edge of the second through groove 8;

[0037] Specifically, by providing a clearance between the elastic protrusion 9 and the two side edges of the second through groove 8, it is ensured that the elastic protrusion 9 can smoothly fill the gap between the plug-in board 1 and the track.

[0038] In this embodiment, the height of the middle position of the elastic protrusion 9 is lower than the height of the clamping board 7, and there is a second insertion gap between the projection of the elastic protrusion 9 on the fixed board 2 and the projection of the clamping board 7 on the fixed board 2;

[0039] Specifically, the height of the middle position of the elastic protrusion 9 is lower than the height of the clamping board 7, so as to ensure that after the track is inserted into the first insertion gap, the elastic protrusion 9 can be located below the track. At the same time, there is a second insertion gap between the projection of the elastic protrusion 9 on the fixed board 2 and the projection of the clamping board 7 on the fixed board 2. After the track is inserted into the first insertion gap, continue to push the plug-in board 1 so that the track continues to be inserted into the second insertion gap, so as to ensure that the elastic protrusion 9 can smoothly abut against the track and avoid shaking.

[0040] In summary, for the metal tail support in the above embodiment of the present utility model, through the symmetrically arranged clamping boards 7, when the metal tail support is inserted into the clamping groove on the hidden rail, the hidden rail can be correspondingly clamped into the first insertion gap, and the installation of the metal tail support can be smoothly completed under the limiting and guiding action of the clamping boards 7. And because the clamping boards 7 contact the hidden rail first, the subsequent elastic protrusions 9 will not generate a large installation resistance, improving the installation efficiency. At the same time, after the metal tail support is installed, under the elastic action of the elastic protrusions 9, the elastic protrusions 9 can abut against the track of the hidden rail, thereby avoiding shaking caused by the gap.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
