Description

Adjustable tension drawer slides

This invention relates to a slide rail mechanism installed on both sides of a drawer, especially a drawer slide rail that allows users to adjust the opening and closing force and buffering time by themselves.

The traditional drawer slide is equipped with a closing mechanism to achieve automatic backward closing, and a buffer (hydraulic cylinder or hydraulic cylinder) is used to buffer the force of the backward return during the drawer closing process, so that the drawer will not be subjected to excessive force. When external force moves, a loud collision occurs with the outer frame.

Such drawers with a buffer closing function are mostly equipped with springs to achieve automatic closing effects. However, the spring design often cannot adjust the tension, which often causes inconvenience in different usage situations. If the load of the drawer is too heavy, the automatic closing action will not be smooth due to insufficient spring tension. On the contrary, if the load of the drawer is too light, the spring tension will be too large, causing noise and vibration. Therefore, it is different. Drawers for various purposes often need to prepare drawer slide rails with different pulling forces for installation, resulting in manufacturers needing to stock many drawer slide rails for different purposes.

In view of the shortcoming of traditional drawer slides that the tension cannot be adjusted, the conventionally known patent No. TWI516231 discloses a hidden slide rail with adjustable tension. This hidden slide rail uses a spring adjustment member with multiple groove rails (4 ), a spring adjustment seat achieves multi-stage position adjustment by changing the linear position of the spring adjustment seat, so that the tensile length of the spring can be changed to multiple (4) different lengths.

However, although this kind of hidden slide rail can adjust the tension, it can only adjust the tension to a few predetermined values. For drawers where a single drawer slide rail is used in various fields, the tension adjustment range is still insufficient. .

The main purpose of this creation is to provide a drawer slide that changes the length of the spring by rotating the adjustment member, thereby changing the opening and closing force and buffer closing time of the drawer, allowing the user to independently adjust it to the best use state that meets personal needs.

The main purpose of this creation is that the adjustment piece can rotate between 0 degrees and 180 degrees, and can be positioned at any angle, so that the spring can be adjusted to the required size within a length range steplessly, thereby improving the drawer slide. rail practicality.

Another purpose of this invention is that all components of the drawer slide can be directly assembled manually without using additional hand tools for installation, thereby simplifying the assembly of the drawer slide and saving assembly time.

In order to achieve the aforementioned purpose, the drawer slide with adjustable tension of the present invention includes: a fixed bracket, a sliding piece, a spring connecting piece, a damper, a spring and an adjusting piece, wherein the fixed bracket is constructed with an adjustment space; The sliding part is movably assembled on the fixed bracket; the spring connecting part is movably arranged in the adjustment space; the damper is connected between the sliding part and the fixed bracket; the spring is connected between the sliding part and the spring between the connecting pieces; and the adjusting piece is assembled on the fixed bracket, and the spring connecting piece is inserted into the adjusting space.

The adjusting member of the present invention can rotate relative to the fixed bracket, so that the spring connecting piece is pushed by the adjusting piece and moves along a linear path; when the spring connecting piece and the fixed bracket are relatively displaced, a gap is formed between the spring connecting piece and the fixed bracket. The separation distance between the sliders will be changed.

In a possible embodiment, the fixed bracket has a receiving groove for fixing the damper, a track portion extending outwardly in conjunction with the receiving groove, and a first channel communicating with the adjustment space; the sliding member has a The track portion is assembled with a groove rail and a second channel aligned with the first channel, and the spring is disposed in the first channel and the second channel to connect the sliding member and the spring connecting member.

The track part has a moving groove, and the sliding part has a deflectable tenon part to be inserted into the moving groove; the moving groove is provided with a linear trajectory and a curved trajectory in sequence. When the tenon part of the sliding part After moving from the linear trajectory to the curved trajectory, the tenon portion will deflect from an initial position to a blocking position, so that the sliding member is temporarily stopped and cannot be displaced relative to the fixed bracket.

The adjustment piece includes a stop portion that can contact the fixed bracket. The top surface of the stop portion is provided with a fitting portion that can be inserted by a hand tool. An insertion portion extends from the bottom surface of the stop portion, and the surrounding structure of the stop portion There are a plurality of inwardly concave latching slots and a plurality of outwardly protruding latching blocks.

The spring connector has a linear slot longer than the insertion portion and a clamping wall capable of positioning the spring, and the end of the spring has a recessed portion with a reduced diameter to match the contour of the card resisting wall.

The adjustment member can be rotated to any angle by the hand tool to complete the stepless adjustment of the spacing distance, so that the spring connecting member can reciprocate on the linear path.

In addition, the fixed bracket has a side opening to communicate with the adjustment space. The side opening has an insertion area conforming to the side view profile of the spring connector and a restriction area with a height smaller than the side view profile, so that the spring connection Accessories can enter the adjustment space from the insertion area.

When the spring connecting piece is connected by the adjusting piece, the spring connecting piece can only move along the straight path in the restricted area; when the spring connecting piece is separated from the adjusting piece, the spring connecting piece can move from the adjusting piece again. The inserted area leaves this adjustment space.

The characteristic of this creation is that the adjusting piece is connected to the fixed bracket in a screwed manner, so that the adjusting piece can be rotated from 0 to 180 degrees relative to the fixing device, and can be stopped at any angle and positioned so that the spring connecting piece can By being pushed along a straight path, the spring can be adjusted to the required size within a length range without any stage, and the drawer's opening and closing force and buffer closing time will be changed simultaneously. The user will be able to independently adjust the tension to match the actual situation. Best condition for use.
