Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of drawer guide rail accessories, especially to an energy storage check device suitable for a rebound box. BACKGROUND

[0002] In the field of furniture drawers, rebound type drawers often use installed drawer rebounders to achieve touch pressure to open and close, such as the prior art in Chinese patents CN213282174 U, a guide rail rebounder, CN2022109394963, a press rebound type guide rail rebound box, CN217039387U, a new press type rebound self-locking device of a hidden slide rail, etc. The functions are relatively simple. The more complex the functional structure of the existing rebound self-closing box product is, the worse the structural stability is. Especially in the actual use process, it is easy to cause abnormal problems such as jamming and impact, resulting in excessive complaints and quality problems. In addition, the above-mentioned drawer rebounder has certain requirements for user thrust. When the thrust is too small, it is easy to cause the drawer to be unable to open and the self-closing buffer rebound box to be unable to open. Sometimes the return amplitude is large, which is easy to cause impact on the human body, especially children, and there is a certain safety hazard and influence on the user experience. SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art and providing an energy storage check device suitable for a rebound box, which can effectively limit the rebound return amplitude and has a partial energy storage effect.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an energy storage check device suitable for a rebound box, which comprises a box body, a rebound slide seat provided on the box body in front and back direction sliding mode, and an energy storage check piece pivotally connected to the rebound slide seat. The box body is formed with a check slide channel for sliding cooperation of the energy storage check piece. The check slide channel is composed of a cyclically connected energy storage section and a rebound section. When the rebound slide seat moves backward relative to the box body, the energy storage check piece moves along the energy storage section correspondingly. Conversely, when the rebound slide seat moves forward relative to the box body, the energy storage check piece moves along the rebound section correspondingly. At least one check stop position for stopping and limiting the forward movement of the energy storage check piece is formed in the area of the energy storage section.

[0005] Further, the area of the energy storage section comprises at least one set of slide channel units. Each set of slide channel units comprises a horizontal slide channel, an uphill slide channel and a downhill slide channel connected in sequence. Each check stop position is arranged adjacent to the upper position of each uphill slide channel to stop and limit the forward movement of the energy storage check piece in the uphill slide channel.

[0006] Further, a rebound elastic piece is arranged between the rebound slide seat and the box body.

[0007] Further, the self-latching bumping piece is arranged on the box body and can be relatively contacted with the rebounding slide base, and the self-latching bumping piece can be locked and positioned or unlocked during sliding relative to the box body; and the self-latching elastic piece is arranged between the self-latching bumping piece and the rebounding slide base.

[0008] The rebounding box energy storage check valve device designed by the utility model has the advantages that the functions of limiting backtracking and energy storage are ingeniously combined, and the comprehensive performance of the equipment is significantly improved.

DETAILED DESCRIPTION

[0014] In order to make the utility model understood easily, the utility model will be described more fully below with reference to the drawings. The drawings show the preferred embodiments of the utility model. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0015] Referring to the drawings Figures 1-4As shown, in the present embodiment, a kind of energy storage check device suitable for bounce box, here, for easy explanation, define the drawer opening direction as forward, the drawer closing direction is rearward, specific application is in the lower rail of drawer slide, by setting the fixed block 100 of cooperation with it on the upper rail of drawer slide (not shown in drawing), self-closing buffer bounce specifically includes box body 1, front and rear directional sliding self-closing impact piece 2 on box body 1 and bounce slide 3, wherein, self-closing impact piece 2 can be locked and limited or unlocked sliding relative to box body 1 during sliding, specifically, the self-closing impact piece 2 of the present embodiment is composed of self-closing slide and movable block 22 pivotally connected to the front end of self-closing slide, which is slid forward and rearward on box body 1, and the movable block 22 is formed with an arc-shaped stop position for abutting and cooperating with the pre-set fixed block 100 on the drawer slide;Secondly, the front position of box body 1 is formed with an empty slot for the movable block 22 of self-closing impact piece 2 to swing in or out, that is, when the drawer slide is pulled out, the fixed block 100 is embedded in the arc-shaped stop position to synchronously drive the movable block 22 and the self-closing slide to move forward relative to the box body 1, until the movable block 22 swings into the empty slot, the fixed block 100 can be disengaged from the arc-shaped stop position, and since the movable block 22 is limited in the empty slot, the self-closing slide remains in a stationary state;Conversely, when the drawer slide is pushed in, the fixed block 100 abuts against the movable block 22 and gradually embeds in the arc-shaped stop position, so that the movable block 22 is pressed to swing out of the empty slot, and then the fixed block 100, the movable block 22 and the self-closing slide move backward synchronously.

[0016] In the present embodiment, a self-closing elastic member 5 is arranged between the self-closing impact piece 2 and the bounce slide 3, i.e., the two ends of the self-closing elastic member 5 are connected with the tail of the self-closing impact piece 2 and the bounce slide 3 respectively, wherein, when the self-closing impact piece 2 and the bounce slide 3 are relatively far away, the self-closing elastic member 5 is stretched to store energy, and the self-closing impact piece 2 and / or the bounce slide 3 need to overcome the tensile elastic force generated by the self-closing elastic member 5 to move away, thereby achieving the effect of energy storage;Conversely, when the self-closing impact piece 2 and the bounce slide 3 are relatively close, the self-closing elastic member 5 releases energy and resets, and the self-closing impact piece 2 and / or the bounce slide 3 are relatively close under the elastic force generated by the self-closing elastic member 5.

[0017] In the present embodiment, a bounce elastic member is arranged between the bounce slide 3 and the box body 1, and the bounce elastic member is a compression spring, one end of the bounce elastic member is fixedly connected with the tail of the bounce slide 3, and the other end of the bounce elastic member elastically abuts against the box body 1, specifically, when the bounce slide 3 moves backward relative to the box body 1, the bounce elastic member is compressed to store energy, and the bounce slide 3 needs to overcome the compression reaction force generated by the bounce elastic member to move backward;Conversely, when the bounce slide 3 moves forward relative to the box body 1, the bounce elastic member is stretched to reset and release energy, and the bounce slide 3 moves forward relative to the box body 1 under the elastic force generated by the bounce elastic member.

[0018] In the embodiment, in order to improve the situation that the drawer and the self-closing buffer rebound box are retracted and opened due to insufficient user thrust during actual use, an energy storage check member is further pivoted to the rebound sliding seat 3, and the box body 1 is formed with an energy storage check sliding groove 13 for sliding cooperation with the energy storage check member (that is, the energy storage check member is formed with an energy storage check shaft portion for slidingly embedded in the energy storage check sliding groove 13). The energy storage check sliding groove 13 is composed of an energy storage segment 131 and a rebound segment 132 which are in circulation. When the rebound sliding seat 3 moves backward relative to the box body 1, the energy storage check member moves along the energy storage segment 131 correspondingly. Conversely, when the rebound sliding seat 3 moves forward relative to the box body 1, the energy storage check member moves along the rebound segment 132 correspondingly. In addition, at least one energy storage check stop position 133 for stopping and limiting the forward movement of the energy storage check member is formed in the region of the energy storage segment 131. The energy storage check member will jump over the energy storage check stop position 133 during normal backward movement along the energy storage segment 131, and will not interfere with the normal backward movement. However, once the thrust is insufficient, the rebound sliding seat 3 will drive the energy storage check member to move forward along the energy storage segment 131 under the elastic force of the rebound elastic member, and will be clamped into the adjacent energy storage check stop position 133, thereby limiting the retraction range and achieving the energy storage effect. At the same time, when the user closes the drawer again, no additional force is required to normally close the drawer.

[0019] In the embodiment, the region of the energy storage segment 131 includes at least one set of sliding groove units. Those skilled in the art can set a corresponding number of sliding groove units according to the actual required number of energy storage stages. For the convenience of explanation, two sets of sliding groove units are taken as an example for explanation. The two sets of sliding groove units are sequentially connected to form the energy storage segment 131. Specifically, each set of sliding groove units includes a horizontal sliding groove 1311, an uphill sliding groove 1312 and a downhill sliding groove 1313 which are sequentially connected and through, and each energy storage check stop position 133 is arranged adjacent to the uphill sliding groove 1312 above the position to stop and limit the forward movement of the energy storage check member in the uphill sliding groove 1312. That is, when the user pushes the drawer to drive the rebound sliding seat 3 and the energy storage check member to move backward, the energy storage check member in the normal state will slide along the horizontal sliding groove 1311, the uphill sliding groove 1312 and the downhill sliding groove 1313 in sequence, and will jump over the adjacent energy storage check stop position 133 during movement along the uphill sliding groove 1312. Once the thrust is insufficient, the rebound sliding seat 3 will drive the energy storage check member to move forward along the energy storage segment 131 under the elastic force of the rebound elastic member, so as to be horizontally clamped into the adjacent energy storage check stop position 133 when moving forward to the uphill sliding groove 1312, thereby limiting the retraction range and achieving the energy storage effect.

[0020] The above-described embodiments are only preferred embodiments of the present application, and do not limit the present application in any form. Any skilled person in the art, without departing from the technical scheme of the present application, can make more possible changes, modifications and refinements to the technical scheme of the present application by using the disclosed technical content, or modifications, which are equivalent embodiments of the present application. Therefore, any equivalent changes within the technical scheme of the present application, according to the idea of the present application, should be covered within the protection scope of the present application.
