Description

Technical Field

[0001] The invention relates to the field of hardware accessories, and in particular to a rebounder and a cabinet door structure capable of realizing automatic buffering closing of a door leaf. Background Art

[0002] A rebounder is a switch used on furniture such as cabinets and drawers. After the rebounder is installed on the cabinet door, there is no need to use a handle when opening and closing the cabinet door. The door can be opened and closed by pressing the door panel.

[0003] The conventional rebounders on the market only have a pop-up function. When the door leaf is pressed and touches the rebounder, the rebounder is released due to the internal elastic force, and the adjusting rod on the rebounder pops out and pushes the door leaf to open a certain distance, thereby realizing the opening of the door leaf; when the door needs to be closed, the door leaf is closed to the rebounder adjusting rod and stops. At this time, the door leaf is still open a certain distance and is not closed. The door leaf needs to be pressed again to lock the hook inside the rebounder before it can be closed; the entire door closing process requires waiting and pressing again, and the action is passive and more troublesome.

[0004] In view of the above problems, how to develop a rebounder that can simplify the door closing action is a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0005] In order to overcome the defects of the above-mentioned prior art, the present invention provides a rebounder and a cabinet door structure that can realize the automatic buffering closing function of the door leaf. During the entire door closing process, the door leaf is closed by external force only, and there is no need to press the door leaf again to close it like a traditional rebounder, thereby simplifying the door closing action.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A rebounder capable of realizing automatic buffer closing of a door leaf, comprising:

[0008] case;

[0009] An inner bracket is slidably disposed in the shell and can extend out of the shell; an adjusting rod is slidably disposed on the inner bracket and can extend out of the shell and is used to contact the door leaf, and the adjusting rod and the inner bracket are relatively fixed by a clamping structure;

[0010] A support member, which is disposed in the housing and provides a supporting force for the inner bracket;

[0011] When closing the door leaf, under the combined effect of the closing force of the door leaf and the supporting force provided by the support member, the adjusting rod can slide backward relative to the inner bracket and the two can be relatively fixed through the clamping structure, thereby realizing automatic closing of the door leaf.

[0012] Therefore, when the door leaf is closed, the door leaf first contacts the adjustment rod, and under the action of the closing force of the door leaf, the adjustment rod is driven to slide backward relative to the inner bracket. In this process, the inner bracket does not move or moves slowly under the supporting force provided by the support member until the adjustment rod and the inner bracket are relatively fixed by the clamping structure, and then the door leaf can be automatically closed.

[0013] The rebounder of the present invention, by providing a support member, only requires external human force to close the door leaf during the entire door closing process, and then the door leaf can be automatically closed by the closing force of the door leaf. There is no need to press the door leaf again to close it like a traditional rebounder, thereby simplifying the door closing action.

[0014] Furthermore, the support member is a damper, which includes a cylinder body and a piston rod that can be movably extended and retracted on the cylinder body, and any one of the cylinder body and the piston rod is connected to the inner bracket to provide supporting force.

[0015] Specifically, the damper is a damping cylinder.

[0016] Furthermore, after the adjusting rod and the inner bracket are relatively fixed by the clamping structure, the inner bracket can slide backward relative to the shell under the action of the closing force of the door leaf, thereby compressing the cylinder body or the piston rod until the door leaf is completely buffered and closed.

[0017] Therefore, when the adjusting rod and the inner bracket are relatively fixed by the clamping structure, the rebounder is in a non-elastic state, and the inner bracket can slowly slide backward relative to the housing under the action of the door leaf closing force and compress the cylinder or piston rod at the same time until the door leaf is completely closed with buffering. Therefore, by setting the damper, the rebounder has a buffering function, which not only improves the service life of the door leaf, but also eliminates the need for expensive buffer hinges for the door leaf hinges, thereby improving the door leaf function while reducing the cost of door leaf accessories.

[0018] Furthermore, one end of the adjusting rod is used to contact the door leaf, and the other end is connected to a pressing block;

[0019] The clamping structure includes a notch provided on the inner bracket and a hook provided on the pressure block and clamped with the notch; or, the clamping structure includes a hook provided on the inner bracket and a notch provided on the pressure block and clamped with the hook.

[0020] Therefore, when the door leaf is closed, the adjusting rod can slide backward relative to the inner bracket until the hook is engaged with the notch, and the adjusting rod and the inner bracket can be relatively fixed.

[0021] Furthermore, it also includes a first elastic member arranged on the inner bracket, one end of the first elastic member abuts against the inner wall of the inner bracket, and the other end abuts against the pressing block;

[0022] When the door leaf is in a closed state, the door leaf is pressed to disengage the hook in the snap-fit ​​structure from the slot, and the first elastic member releases its elastic force and drives the pressing block and the adjusting rod to slide forward relative to the inner bracket to open the door leaf.

[0023] Thus, when the door leaf is closed, the adjusting rod can slide backward relative to the inner bracket and drive the pressing block on the adjusting rod to compress the first elastic member until the hook is engaged with the notch. When the door leaf is in a closed state, by pressing the door leaf to disengage the hook from the notch, the first elastic member releases its elastic force and drives the adjusting rod to reset to push the door leaf out, thereby realizing the opening of the door leaf.

[0024] Furthermore, it also includes a linkage mechanism arranged on the inner bracket, when the first elastic member releases the elastic force and drives the pressing block and the adjusting rod to move forward, the inner bracket can be driven to slide forward relative to the shell through the linkage mechanism.

[0025] Furthermore, the linkage mechanism includes a transmission mechanism, a telescopic member and a second elastic member arranged on the inner bracket, wherein:

[0026] The telescopic member is slidably disposed on the inner bracket and partially extends out of the inner bracket, and the second elastic member is sleeved on the portion of the telescopic member extending out of the inner bracket, and one end of the second elastic member is in conflict with the telescopic member, and the other end is in conflict with the outer wall of the inner bracket;

[0027] When the first elastic member releases its elastic force and drives the pressing block and the adjusting rod to slide forward, the transmission mechanism can drive the telescopic member to slide, and the second elastic member releases its elastic force to drive the inner bracket to slide forward relative to the shell.

[0028] Thus, when the door leaf is closed, the adjusting rod can slide backward relative to the inner bracket, and drive the telescopic member to move through the transmission mechanism to compress the second elastic member; when the door leaf is in a fully closed state, the hook is disengaged from the notch by pressing the door leaf, the first elastic member releases the elastic force and drives the pressing block and the adjusting rod to extend and reset, and then drives the telescopic member to reset through the transmission mechanism. At the same time, the second elastic member releases the elastic force and drives the inner bracket to move forward relative to the shell, thereby pushing the cylinder or piston rod on the damper to extend and reset.

[0029] Furthermore, the transmission mechanism includes a first rack, a gear and a second rack which are meshed with each other in sequence for transmission, the first rack is arranged on the pressing block, and the second rack is arranged on the telescopic member.

[0030] Further, the housing comprises an upper housing and a lower housing, the upper housing and the lower housing are connected to each other and form a mounting cavity therein, and the inner bracket and the support member are both arranged on the mounting cavity;

[0031] The upper shell and the lower shell are both provided with through holes through which the inner bracket and the adjusting rod can extend;

[0032] The upper shell and the lower shell are both provided with mounting holes for mounting on a cabinet.

[0033] Furthermore, it also includes a decorative cover for covering the upper shell or the lower shell, and the front and rear sides of the decorative cover are provided with avoidance holes for the inner bracket and the adjusting rod to extend out.

[0034] In addition, the second aspect of the present invention further provides a cabinet door structure, including a cabinet body, a door leaf hinged on the cabinet body, and the above-mentioned rebounder installed on the cabinet body.

[0035] In summary, the rebounder and cabinet door structure of the present invention, which can realize automatic buffering closing of door leaves, have the following beneficial effects:

[0036] (1) The rebounder and cabinet door structure of the present invention only require external force to close the door leaf during the entire door closing process, and there is no need to press the door leaf again to close it like a traditional rebounder, thereby simplifying the door closing action.

[0037] (ii) The rebounder and cabinet door mechanism of the present invention can not only improve the service life of the door leaf, but also the door leaf hinge does not need to use expensive buffer hinges, thereby improving the door leaf function and reducing the cost of door leaf accessories.

DETAILED DESCRIPTION

[0053] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0054] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0056] See also Figure 1-13 The present invention first provides a rebounder 1 that can realize automatic buffer closing of a door leaf, and the rebounder 1 is used to be installed at the top plate, side plate, etc. of a cabinet. The rebounder 1 only needs an external force to close the door leaf, and then the door leaf can be automatically closed by the closing force of the door leaf, without pressing the door leaf again to close it like the traditional rebounder 1, thereby simplifying the action of closing the door.

[0057] See also Figure 1 The rebounder 1 includes a shell and an inner bracket 13 arranged in the shell. The shell is rectangular in shape and includes an upper shell 11 and a lower shell 12 connected to each other. The upper shell 11 and the lower shell 12 are connected to each other and form an installation cavity inside; the inner bracket 13 is slidably arranged on the installation cavity and partially extends out of the shell. An adjustment rod 14 that can extend out of the shell and is used to contact the door leaf is slidably arranged on the inner bracket 13, and the adjustment rod 14 and the inner bracket 13 are relatively fixed by a clamping structure. In addition, the rebounder 1 also includes a support member that is arranged in the installation cavity and provides a supporting force for the inner bracket 13. When the door leaf is closed, under the combined action of the closing force of the door leaf and the supporting force provided by the support member, the adjustment rod 14 can slide backward relative to the inner bracket 13 and the two can be relatively fixed by the clamping structure, thereby realizing automatic closing of the door leaf.

[0058] Therefore, when the door leaf is closed, the door leaf first contacts the adjustment rod 14, and under the action of the closing force of the door leaf, the adjustment rod 14 is driven to slide backward relative to the inner bracket 13. In this process, the inner bracket 13 does not move or moves slowly under the supporting force provided by the support member until the adjustment rod 14 and the inner bracket 13 are relatively fixed by the clamping structure, and then the door leaf can be automatically closed.

[0059] The rebounder 1 of the present invention, by providing a support member, only requires external force to close the door leaf during the entire door closing process, and then the door leaf can be automatically closed by the closing force of the door leaf. There is no need to press the door leaf again to close it like the traditional rebounder 1, thereby simplifying the door closing action.

[0060] In this embodiment, a plurality of studs 111 are provided in the upper shell 11, and a plurality of second mounting holes 121 corresponding to the plurality of studs 111 are provided on the lower shell 12. Thus, when screws are passed through the second mounting holes 121 and threadedly connected with the studs 111, a fixed connection between the upper shell 11 and the lower shell 12 can be achieved. In addition, the ends of the upper shell 11 and the lower shell 12 are both provided with through holes 114 through which the inner bracket 13 and the adjustment rod 14 can extend.

[0061] In addition, the upper shell 11 and the lower shell 12 are both provided with a plurality of first mounting holes 112 and third mounting holes 122 which are arranged correspondingly, and the first mounting holes 112 and the third mounting holes 122 are connected to each other and form a through hole. Therefore, when it is necessary to fix the upper shell 11 or the lower shell 12 on the cabinet door, it is only necessary to use screws to pass through the through holes and be threadedly connected to the cabinet door to fix the rebounder 1 on the cabinet door.

[0062] See also Figure 1 The rebounder 1 also includes a decorative cover 10 for covering the upper shell 11 or the lower shell 12. The front and rear sides of the decorative cover 10 are provided with avoidance holes 101 for the inner bracket 13 and the adjustment rod 14 to pass through. In addition, the outer walls of the upper shell 11 are provided with first card slots 113, and the outer walls of the lower shell 12 are provided with second card slots 123. The first card slots 113 and the second card slots 123 have the same structure; the inner walls of the decorative cover 10 are provided with buckles 102 that are engaged with the first card slots 113 or the second card slots 123. Therefore, when the decorative cover 10 is covered on the upper shell 11 or the lower shell 12 until the buckle 102 is engaged with the first card slots 113 or the second card slots 123, the decorative cover 10 can be fixed on the shell.

[0063] See also Figure 2The inner bracket 13 is in a substantially "H" shape and includes a first vertical portion 131, a second vertical portion 132, and a horizontal portion 133 respectively connecting the first vertical portion 131 and the second vertical portion 132. The adjusting rod 14 is slidably disposed at the front end of the first vertical portion 131 of the inner bracket 13, and the front end of the adjusting rod 14 is used to contact the door leaf, and the rear end of the adjusting rod 14 is connected to a long strip-shaped pressing block 141; a fixing column 1311 is horizontally disposed at the rear end of the first vertical portion 131 of the inner bracket 13, and a first elastic member 16 is sleeved on the fixing column 1311, one end of the first elastic member 16 contacts the inner wall of the inner bracket 13, and the other end contacts the pressing block 141; the pressing block 141 is provided with an avoidance groove for avoiding the fixing column 1311.

[0064] In this embodiment, the first elastic member 16 is an elastic compression spring.

[0065] See also Figure 1-3 The clamping structure includes a notch 13131 provided on the inner bracket 13 and a hook 1411 provided on the pressing block 141 and clamped with the notch 13131. Specifically, a guide groove 1314 is provided in the middle of the first vertical portion 131 of the inner bracket 13, a protrusion 1313 and a wedge block 1315 are provided on the guide groove 1314, a notch is provided on the side wall of the protrusion 1313 to form the notch 13131, and a guiding inclined surface is provided on the side wall of the wedge block 1315.

[0066] Thus, when the door leaf is closed, the door leaf can drive the adjusting rod 14 and the pressing block 141 to overcome the elastic force of the first elastic member 16 and slide backward relative to the inner bracket 13, thereby driving the hook 1411 on the pressing block 141 to slide along the guide groove 1314 until the hook 1411 is engaged with the notch 13131 on the protrusion 1313, and the first elastic member 16 is in a compressed state, at which time the adjusting rod 14 is fixed and in a retracted state, that is, the door leaf is in a closed state. When the door leaf is in a fully closed state, by pressing the door leaf again, the adjusting rod 14 can be driven to slide backward again, at which time the hook 1411 will move along the guiding inclined surface of the wedge block 1315 and disengage from the notch 13131, and the first elastic member 16 releases the elastic force and drives the adjusting rod 14 to slide along the guide groove 1314 and gradually move forward until it is fully reset, at which time the adjusting rod 14 is in an extended state, that is, the door leaf is in an open state.

[0067] In this embodiment, the clamping structure further includes a first pressing plate 1412 , which is fixed to the pressing block 141 by screws and presses the hook 1411 to prevent the hook 1411 from being separated from the pressing block 141 during movement.

[0068] Of course, in other embodiments, the setting positions of the snap-fit ​​structures may also be interchanged, that is, a notch 13131 is provided on the pressing block 141 and a hook 1411 is provided on the inner bracket 13 , which can also achieve the same technical effect, and are not limited here.

[0069] See also Figure 1 The support member is a damper 15, and includes a cylinder 151 and a piston rod 152 that can be movably extended and retracted on the cylinder 151. The side wall of the first vertical portion 131 of the inner bracket 13 is provided with a protrusion 1312, and the rod head of the piston rod 152 is connected to the protrusion 1312 to provide supporting force.

[0070] In this embodiment, the damper 15 is a damping oil cylinder. Of course, in other embodiments, the damper 15 can also be a damping cylinder or other supporting member with a buffering function, which is not limited here.

[0071] Therefore, when the adjusting rod 14 and the inner bracket 13 are relatively fixed by the clamping structure, the rebounder 1 is in a non-elastic state, and the inner bracket 13 can slowly slide backward relative to the shell under the action of the door leaf closing force and compress the piston rod 152 at the same time until the door leaf is completely closed by buffering. It can be seen that by setting the damper 15, not only the rebounder 1 has a buffering function, but also the service life of the door leaf is increased, and the door leaf hinge does not need to use an expensive buffer hinge, which improves the door leaf function and reduces the cost of door leaf accessories.

[0072] Of course, in other embodiments, the damper 15 can also be reversed, that is, the cylinder body 151 on the damper 15 is connected to the inner bracket 13. At this time, the inner bracket 13 moves and drives the cylinder body 151 to move telescopically relative to the piston rod 152, which can also achieve the same buffering effect. This is not limited here.

[0073] See also Figure 1 The rebounder 1 also includes a linkage mechanism arranged on the inner bracket 13. When the first elastic member 16 releases its elastic force and drives the pressing block 141 and the adjusting rod 14 to move forward, the inner bracket 13 can be driven to slide forward relative to the shell through the linkage mechanism. Specifically, the linkage mechanism includes a transmission mechanism 19, a telescopic member 17, and a second elastic member 18. The telescopic member 17 is slidably arranged on the second vertical portion 132 of the inner bracket 13 and its tail extends out of the inner bracket 13. The second elastic member 18 is sleeved on the portion of the telescopic member 17 extending out of the inner bracket 13, and one end thereof is in conflict with the telescopic member 17, and the other end is in conflict with the outer wall of the inner bracket 13. The transmission mechanism 19 includes a first rack 191, a gear 192, and a second rack 193 that are meshed and transmitted in sequence. The first rack 191 is arranged on the pressing block 141, the gear 192 is arranged on the horizontal portion 133 of the inner bracket 13, and the second rack 193 is arranged on the telescopic member 17.

[0074] In this embodiment, the second elastic member 18 is an elastic compression spring; the telescopic member 17 is a telescopic rod and is integrally formed with the second rack 193; and the pressing block 141 is integrally formed with the first rack 191.

[0075] Of course, in other embodiments, the transmission mechanism may also be a pulley transmission mechanism, etc., which is not limited here.

[0076] Thus, when the door leaf is closed, the door leaf drives the adjusting rod 14 to slide backward relative to the inner bracket 13, and drives the telescopic member 17 to move through the transmission mechanism 19 to compress the second elastic member 18; when the door leaf is in a fully closed state, the hook 1411 is disengaged from the slot 13131 by pressing the door leaf, and the adjusting rod 14 and the pressing block 141 can be reset under the elastic force of the first elastic member 16, and the telescopic member 17 is extended and reset through the transmission mechanism 19. At this time, the second elastic member 18 releases the elastic force and pushes the inner bracket 13 to move forward relative to the shell, thereby pushing the piston rod 152 on the damper 15 to extend and reset.

[0077] In addition, the transmission mechanism 19 further includes a second pressing plate 194, which is fixed to the gear 192 by screws and presses the gear 192, thereby preventing the gear 192 from deviating during the meshing transmission process.

[0078] See also Figure 5-13 The working process of the rebounder of the present invention is as follows:

[0079] When the door leaf is closed, the door leaf first contacts the adjustment rod 14 during the closing process, and the adjustment rod 14 slides backward under the action of the closing force of the door leaf. In this process, the inner bracket 13 does not move or moves slowly under the action of the damper 15, so that the adjustment rod 14 drives the pressing block 141 to move together and compress the first elastic member 16. While the hook 1411 on the pressing block 141 moves along the guide groove 1314, the first rack 191 on the pressing block 141 drives the second rack 193 and the telescopic member 17 to move and compress the second elastic member 18 through the gear 192, until the hook 1411 on the pressing block 141 hooks the notch 13131, the adjustment rod 14 is in a locked state, and the door leaf can be automatically closed at this time. In this process, the inner bracket 13 has not slid into place under the action of the damping cylinder. After the above actions are locked, the first elastic member 16 and the second elastic member 18 are both in a compressed and locked state. At this time, there is no elastic force between the inner bracket 13 and the housing. Under the action of the closing force of the door leaf, the inner bracket 13 slides backward along the housing and slowly compresses the piston rod 152 of the damper 15 until the door leaf is completely buffered and closed, thereby achieving a buffering effect.

[0080] When the door leaf is in a fully closed state, by pressing the door leaf, the door leaf touches the adjusting rod 14 and drives the hook 1411 on the pressing block 141 to overcome the elastic force of the first elastic member 16 and move backward. At this time, the hook 1411 disengages from the limit of the slot 13131, thereby releasing the elastic force of the first elastic member 16. The adjusting rod 14 extends outward and resets during the process of the first elastic member 16 releasing the elastic force, thereby realizing the opening of the door leaf; when the adjusting rod 14 and the pressing block 141 pop out, the telescopic member 17 is driven to slide and reset through the transmission mechanism 19, and the elastic force of the second elastic member 18 is released synchronously. The elastic force causes the inner bracket 13 to move forward relative to the shell, thereby pulling out and resetting the piston rod 152 on the damper 15 until the rebounder 1 returns to its initial state.

[0081] In addition, the second aspect of the present invention further provides a cabinet door structure, comprising a cabinet body, a door leaf hinged on the cabinet body, and the above-mentioned rebounder 1 installed on the cabinet body.

[0082] In summary, the rebounder 1 and the cabinet door structure capable of realizing automatic buffering closing of a door leaf of the present invention have the following beneficial effects:

[0083] (i) With the rebounder 1 and the cabinet door structure of the present invention, the entire door closing process only requires the door leaf to be closed by external force, and there is no need to press the door leaf again to close it like the traditional rebounder 1, thereby simplifying the door closing action.

[0084] (ii) The rebounder 1 and the cabinet door structure of the present invention, because the rebounder 1 has a buffering function, not only improves the service life of the door leaf, but also eliminates the need for expensive buffering hinges for the door leaf hinges, thereby improving the door leaf function and reducing the cost of door leaf accessories.
