Description

Technical Field

[0001] The utility model relates to the technical field of drawer slide rails, in particular to a silent drawer slide rail. Background Art

[0002] Drawer slides are hardware connection parts fixed to the cabinet body of furniture to allow the drawers or cabinet panels of furniture to move in and out. Drawer slides are suitable for connecting drawers of wooden and steel drawers in cabinets, furniture, document cabinets, bathroom cabinets and other furniture.

[0003] Existing drawer slides usually slide between sliders and slide grooves. This sliding connection method not only causes a large friction coefficient of the slider inside the device, but also causes certain wear and tear after long-term use, and it produces certain noise. When the drawer slides, it cannot be fixed and limited at a certain position, thereby reducing the scope of use of the device. Therefore, we propose a silent drawer slide to solve the above-mentioned problems. Utility Model Content

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a silent drawer slide rail, comprising a support plate and a drawer, wherein two rotating shafts are symmetrically and rotatably mounted on the bottom end of the drawer, and wheels are rotatably mounted on both ends of each rotating shaft, and two fixed plates are symmetrically and fixedly mounted on the top end of the support plate, and a slide groove is provided on the top end of each fixed plate, and each wheel is slidably connected to the top end of each slide groove, and a plurality of limit mechanisms are arranged inside each slide groove;

[0008] The limiting mechanism comprises a spring, a limiting groove is arranged at the top of the slide groove, the spring is fixedly installed at the inner top of the limiting groove, and a limiting plate is fixedly installed at the top of the spring.

[0009] Preferably, guide plates are symmetrically fixedly mounted on both ends of each of the limit plates.

[0010] Furthermore, a plurality of rolling balls are installed on the top of the support plate in parallel and rolling manner, and the outer side wall of each rolling ball is in contact with the bottom end of the drawer.

[0011] Furthermore, a handle is fixedly mounted on the outer side wall of the drawer.

[0012] Based on the above solution, two through holes are symmetrically provided on the handle.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a silent drawer slide rail, which has the following beneficial effects:

[0015] The silent drawer slide rail slides on the slide groove by the wheel, so that the drawer can slide on the top of the support plate. The limit plate is driven to slide inside the limit groove synchronously by the spring expansion and contraction, so that the sliding wheel is stopped and limited, so that the drawer can slide quickly and silently on the top of the support plate, and the drawer can be stopped and limited in different areas, which improves the convenience of the device during use and improves its practicality.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1-4A silent drawer slide comprises a support plate 1 and a drawer 2. Two rotating shafts 4 are symmetrically rotatably installed at the bottom end of the drawer 2. Wheels 3 are rotatably installed at both ends of each rotating shaft 4. Two fixed plates 5 are symmetrically fixedly installed at the top end of the support plate 1. A slide groove 6 is opened at the top end of each fixed plate 5. Each wheel 3 is slidably connected to the top end of each slide groove 6. A plurality of limiting mechanisms are arranged inside each slide groove 6. A plurality of rolling balls 11 are parallelly and rollingly installed at the top end of the support plate 1. The outer wall of each rolling ball 11 is fitted with the bottom end of the drawer 2. By installing the rolling balls 11, the drawer 2 in sliding operation is supported, thereby improving the silent effect of the drawer 2 during sliding operation.

[0024] See also Figure 1-4 The limiting mechanism includes a spring 8, a limiting groove 7 is provided at the top of the slide groove 6, the spring 8 is fixedly installed at the inner top of the limiting groove 7, and a limiting plate 9 is fixedly installed at the top of the spring 8. Guide plates 10 are symmetrically fixedly installed at both ends of each limiting plate 9. By installing the guide plates 10, it is convenient to guide the wheel 3 to the top of the limiting plate 9. The silent drawer slide rail slides on the slide groove 6 through the wheel 3, so as to facilitate the sliding operation of the drawer 2 on the top of the support plate 1. The limiting plate 9 is synchronously driven to slide inside the limiting groove 7 while the spring 8 is extended and retracted, so as to stop and limit the sliding wheel 3, so as to facilitate the drawer 2 to slide quickly and quietly on the top of the support plate 1, and it is convenient to make the drawer 2 stationary and limit the position for different areas, which improves the convenience of the device during use and improves practicality.

[0025] See also Figure 1 It should also be noted that a handle 12 is fixedly installed on the outer wall of the drawer 2. By installing the handle 12, it is convenient for the user to slide the drawer 2.

[0026] See also Figure 1 Two through holes 13 are symmetrically provided on the handle 12 , and the through holes 13 are provided to facilitate the user to move the handle 12 .

[0027] In summary, when the silent drawer slide is in use, the drawer 2 is moved horizontally through the handle 12, and the ball 11 is rolled to support and assist the sliding operation of the drawer 2. The drawer 2 moves while synchronously driving the wheel 3 and the rotating shaft 4 to rotate, so that the wheel 3 slides at the top of the slide groove 6, so that the drawer 2 can slide stably. Through the expansion and contraction of the spring 8, the wheel 3 moves to the top of the limit plate 9 with the assistance of the guide plate 10, and then the spring 8 drives the limit plate 9 to move longitudinally under the limit of the limit groove 7, so that the wheel 3 is in a limited state, and the sliding drawer 2 can be fixed and limited.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
