Description

Technical Field

[0001] The invention relates to a damper, in particular to a damper applicable to a hidden rail. Background Art

[0002] As a device that can provide motion resistance, the damper has the function of absorbing energy and reducing shock. Therefore, in order to reduce the excessive noise caused by the impact when closing drawers, doors and windows, the damper structure is often used on the slide rails of drawers, doors and windows. Conventional dampers need to be equipped with springs and cylinder structures of the same length. During the contraction of the spring, the cylinder can be slowly compressed to slowly close the drawers, doors and windows. However, since the length of the cylinder must match the spring, the cylinder length is too long, which will occupy a larger slide rail space and result in a larger slide rail size.

[0008] Furthermore, the compression stroke of the telescopic cylinder is smaller than the sliding stroke of the slider from the first position to the second position.

[0009] Furthermore, there is an inclination angle between the telescopic cylinder and the compression surface, and one end of the telescopic cylinder abuts against the compression surface.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only embodiments of a part of the present invention, rather than all embodiments.

[0029] The present invention provides a hidden rail damper, such as Figure 1-10 As shown, it includes a housing 1 and a damper, wherein the damper includes a tension member 2, a slider 3, a telescopic cylinder 4, and a stop member 5. The slider 3 is slidably installed in the housing 1, and the tension member 2 is connected to the housing 1 and the slider 3 respectively; the slider 3 has a first position and a second position in the housing 1, and the tension member 2 can pull the slider 3 to move from the first position to the second position;

[0030] The limiting member 5 is connected to the slider 3, and the telescopic cylinder 4 is installed on the housing 1; or

[0031] The telescopic cylinder 4 is installed on the slider 3, and the limiter 5 is installed on the housing 1;

[0032] The limiting member 5 is provided with a compression surface 51, and one end of the telescopic cylinder 4 is in direct or indirect contact with the compression surface 51, and the telescopic cylinder 4 and the limiting member 5 have a first relative position and a second relative position; when the tension member 2 pulls the sliding block 3 to move from the first position to the second position, the telescopic cylinder 4 moves from the first relative position to the second relative position; when the telescopic cylinder 4 moves from the first relative position to the second relative position, the telescopic cylinder 4 is gradually compressed.

[0033] Optionally, the compression stroke of the telescopic cylinder 4 is smaller than the sliding stroke of the slider 3 from the first position to the second position.

[0034] There is an angle between the compression surface 51 and the movement direction of the slider 3, and there is an inclination angle between the extension direction of the telescopic cylinder 4 and the compression surface 51. When the telescopic cylinder 4 moves from the first relative position to the second relative position, the telescopic cylinder 4 is gradually compressed under the action of the compression surface 51, and the compression stroke of the telescopic cylinder 4 is smaller than the sliding stroke of the slider 3 from the first position to the second position.

[0035] The embodiment of the present invention sets a compression surface of the limiter so that the force generated by the telescopic cylinder during compression can be converted into resistance in the process of the damper sliding from the first position to the second position, thereby playing a damping role. At the same time, due to the effect of the limiter, the telescopic direction of the telescopic cylinder can be different from the movement direction of the damper. By adjusting the angle between the compression surface of the limiter and the movement direction of the slider, and the inclination angle between the telescopic direction of the telescopic cylinder and the compression surface, it is ensured that the projected length of the compression surface in the compression direction of the telescopic cylinder is the same as the compression stroke, and the projected length in the sliding direction of the slider is the same as the sliding stroke. Compared with traditional dampers, the requirements for the cylinder size are reduced, the space required for the damping member is reduced, and the size of the damping structure is reduced. At the same time, due to the small size of the cylinder, the cost of the damper can be effectively reduced.

[0046] There is a columnar connection structure between the first sliding end and the second sliding end of the sliding guide 6 .
