Description

Slide buffer structure

The invention relates to a drawer slide structure, in particular to a slide buffer structure which has both space saving and cost reduction.

As shown in FIG. 7 , a slide rail structure includes a first slide rail 50 , a buffer device 60 and a second slide rail 70 . The buffer device 60 is provided by a spring 62 of the slide 61 . The sliding member of the connecting member 63 is pivotally provided with a limiting block 64, and the limiting block 64 is convexly disposed with the linking portion 641, and the second sliding rail 70 is slidably disposed on the first sliding rail 50. And engaging the connecting block 71 on the second sliding rail 70, and hooking or disengaging the linking portion 641 of the limiting block 64 through the engaging block 71 to form a buffering stroke of the buffer device 60 with respect to the second sliding rail 70, In the buffer stroke state, the relative position of the second slide rail 70 and the buffer device 60 is restricted by the limiting block 64, so that the engaging block 71 can surely hook the interlocking portion 641 of the limiting block 64, but the above-mentioned conventional structure is detailed. It is not difficult to find that there are still some shortcomings, the main reasons are as follows: (1) The sliding seat 61 cooperates with the relative displacement of the connecting member 63 to form a buffering function with the elastic force of the spring 62, and then the second sliding rail The engaging block 71 of 70 forms a linkage with the connecting member 63, so that the entire mechanism of the sliding seat 61, the connecting member 63 and the spring 62 is complex. Miscellaneous, and need to occupy most of the space of the slide rail, resulting in a large overall thickness of the slide rail, and the structure cost is high, resulting in reduced utility; (2) the slide 61 and the connecting member 63 form a relative displacement And the connecting block 71 of the second sliding rail 70 forms a snap-fit connection with the connecting member 63, so that the buffering stroke is formed with two parts to be connected, and the fitting degree between the members is high, and it is easy to have unconnected or Buffering is not true, that is, there is a smooth buffering action The lack of degree is lacking.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a slide buffer structure for the above-mentioned shortcomings existing in the prior art.

A slide rail is formed with a slide rail, and the slide rail frame is fixed with a limiting member at one end of the slide rail, and the limiting member is pivotally provided with a swinging rod, and the rail rail frame is convexly disposed on the surface of the slide rail. a first sliding rail is slidably disposed on the sliding rail of the sliding rail frame, and the first sliding rail is formed with a receiving groove for the sliding rail of the sliding rail frame, so that the sliding rail frame is blocked by the sliding rail frame The portion of the second sliding rail is disposed at the first sliding rail, and the second sliding rail is disposed at one end of the receiving portion. And the second sliding rail can be coupled with the swinging rod of the limiting member by the limiting seat, a buffering member is slidably disposed at the receiving groove of the first sliding rail, and the buffering member is corresponding to the hook portion There is at least one hook body, and a spring is coupled between the hook body and the hook portion, so that the blocking portion of the slide rail frame is located between the buffer member and the limiting member, so that the first sliding rail and the first sliding rail When the two sliding rails slide into the sliding rail frame to form a fold, the blocking portion of the sliding rail frame can block the buffering member, and then the spring is stretched to achieve the buffering effect before the limiting seat is engaged with the limiting member.

Wherein, the limiting seat is formed with a control slot, and a blocking block is protruded in the control slot, and the swinging rod of the limiting member is movable in the control slot, and the swinging bar is engaged with the blocking block to form a fastening fixed.

Wherein, the hook portion is disposed at a middle position of the buffering member, and the buffering member is disposed The two guiding strips are protruded from one end of the hook body, and the guiding strips are in contact with the inner walls of the two sides of the receiving groove, thereby preventing the buffering member from being skewed and reducing the sliding resistance.

Wherein, the buffer member has two fins extending at the other end of the hook body, and the spring is partially restricted between the fin and the bottom surface of the receiving groove, so that the spring can press the buffer member and keep The spring is stretched in a straight line.

A first main object of the present invention is that the first sliding rail is formed with a receiving groove capable of sliding the buffering member, and a hook portion is protruded in the receiving groove, and the buffering member is spring-coupled to the hook portion. Moreover, the slide rail is convexly provided with a blocking portion at the slideway, and the buffering member is blocked by the blocking portion to form a tensioning of the spring, so that the buffering effect can be achieved in a limited space, thereby replacing the limiting member and the limiting position. The cushioning mechanism of the seat has the effect of reducing the overall volume and reducing the structural cost.

A second main object of the present invention is that the hook portion is disposed at a position of the buffer member, and a guiding strip for engaging the inner walls of the two sides of the receiving groove is protruded at one end of the buffering member, thereby preventing the buffering. The member is biased to catch and reduce the sliding resistance, and the other end of the cushioning member extends with a fin, and the spring is locally limited between the flap and the bottom surface of the receiving groove, so that the spring can press the cushioning member And keeping the spring stretched linearly, thereby controlling the cushioning member to perform a displacement operation in a straight state to improve the stability and smoothness of the cushioning operation.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.
