Description

Technical Field

[0001] The utility model relates to the field of furniture accessories, in particular to an adjusting structure and a rebounder. Background Art

[0002] The ends of door panel rebounders on the market are generally threaded, and the design allows operators to adjust the length of the rebounder by rotating the ends. However, this adjustment method often faces a problem in actual operation: it is difficult for operators to accurately grasp how many turns they have rotated, making it difficult to adjust to the best state in one go. Repeated attempts and adjustments are often required, which undoubtedly increases the complexity and time cost of the operation.

[0003] For example, Chinese patent publication number CN219281477U discloses a cabinet door rebounder, in which the push rod and the adjusting member are connected by the above-mentioned threaded fitting method. Utility Model Content

[0004] The technical problem to be solved by the utility model is to solve at least one of the technical problems mentioned above.

[0005] The solution of the utility model to solve the technical problem is:

[0006] 1. The camshaft of claim 1, wherein the first and second ends of the guide rails are engaged with the guide rails and the adjusting member are engaged with the guide rails, and the adjusting member and the adjusting member are engaged with the guide rails and the adjusting member are engaged with the guide rails.

[0007] The beneficial effects of the present utility model are as follows. When an operator adjusts the extension length of the ejector rod in the fixed sleeve, by rotating the ejector rod, relative rotation is generated between the ejector rod and the adjusting member. Since the adjusting member is designed to be able to slide only relatively left and right in the installation channel in the fixed sleeve and cannot rotate relative to it, therefore, under the tight fit of the first thread and the second thread, the extension length of the ejector rod is accurately adjusted. It should be noted that this sliding design between the adjusting member and the installation channel, combined with the elastic force of the spring, enables the adjusting member to automatically drive the ejector rod to move to the leftmost end when there is no external force, ensuring that the ejector rod tightly abuts against the fixed sleeve. The protrusion provided on the ejector rod is adapted to the recess on the fixed sleeve. When the operator rotates the ejector rod, relative movement will occur between the protrusion and the recess. If the protrusion successfully enters the recess or smoothly disengages from the recess, the operator will clearly feel a sense of jerk. This feedback mechanism allows the operator to clearly understand the number of turns or the angle of rotation of the ejector rod, thus greatly improving the accuracy and efficiency of adjustment. Compared with the threaded connection adjustment method commonly used in the traditional market, the adjustment structure provided by the present utility model is more convenient and intuitive in operation. It effectively solves the problem that it is difficult for the operator to accurately master the number of rotation turns, avoids the cumbersome process of repeated attempts and adjustments, and significantly reduces the complexity and time cost of operation.

[0008] As a further improvement of the above technical solution, the fixed sleeve includes a sleeve body and a sealing cover. The installation channel is formed inside the sleeve body. The sealing cover is fixed on the fixed sleeve, and the sealing cover covers the right end of the installation channel. The right end of the spring abuts against the sealing cover.

[0009] As a further improvement of the above technical solution, a chute extending in the left-right direction is provided on the inner wall of the installation channel. A slider extends from the adjusting member, and the slider is inserted into the chute, and the slider and the chute can slide relatively left and right.

[0010] As a further improvement of the above technical solution, the ejector rod includes a rod body and a shoulder provided on the rod body. The protrusion is provided on the left end face of the shoulder. A limiting step extends from the inner wall of the installation channel, and the aperture at the limiting step is smaller than the outer diameter of the shoulder. The recess is provided on the right end face of the limiting step.

[0011] As a further improvement of the above technical solution, a threaded hole is provided on the right end face of the ejector rod, and the thread of the threaded hole is the second thread.

[0012] As a further improvement of the above technical solution, a plurality of recesses are provided, and the recesses are arranged in a circumferential array centered on the axis of the fixed sleeve. A plurality of protrusions are provided, and the recesses and the protrusions are arranged in one-to-one correspondence.

[0013] The present utility model further provides a rebounder, which includes a base and the adjusting structure in any of the above technical solutions, and the fixed sleeve is fixed on the base.

[0014] The rebounder of the present utility model adopts the above adjusting structure. It effectively solves the problem that the operator is difficult to accurately master the number of rotation circles, avoids the cumbersome process of repeated attempts and adjustments, and significantly reduces the complexity and time cost of operation. The adjusting structure has a wide application prospect in occasions such as door panel rebounders that require precise length adjustment.

[0015] As a further improvement of the above technical solution, the rebounder further includes a hanging nail, a connecting shaft and a tail piece. The tail piece is fixed on the fixed sleeve. The connecting shaft extends in the front-rear direction and is fixed on the tail piece. The right end of the hanging nail is provided in a ring shape, and the right end of the ring of the hanging nail is sleeved on the connecting shaft. The hanging nail and the connecting shaft can rotate relative to each other. The adjusting member is used to limit and guide the hanging nail so that the hanging nail is restricted on the adjusting member or disengaged from the adjusting member.

[0016] As a further improvement of the above technical solution, the adjusting member includes an adjusting block, a first guiding block, a second guiding block, a third guiding block and a fourth guiding block. The adjusting block can slide left and right between the installation channels. A counterbore is provided on the front side of the adjusting block. The first guiding block, the second guiding block, the third guiding block and the fourth guiding block are all fixed on the counterbore. The second guiding block is arranged in the middle of the front side of the adjusting block. The right side of the second guiding block is provided with a first guiding angle, and the opening of the included angle of the first guiding angle faces left. The first guiding block is arranged on the right side of the second guiding block. The right side surface of the first guiding block is provided as an inclined surface.

Detailed implementation manners

[0028] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / linkage relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal linkage structure that can be formed by adding or reducing linkage accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflict.

[0029] Currently, the ends of door panel rebounders on the market generally adopt a threaded connection method, and its design allows operators to adjust the length of the rebounder by rotating the end. However, this adjustment method often faces a problem in actual operation: it is very difficult for operators to accurately grasp how many turns they have rotated, so it is difficult to adjust to the best state at one time, and often need to try and adjust repeatedly, which undoubtedly increases the complexity of operation and the time cost.

[0030] Therefore, as Figures 1 to 8As shown in the figure, the present utility model provides an adjustment structure, which includes a fixed sleeve 1, an adjustment member 2, a push rod 3 and a spring 4; an installation channel extending in the left-right direction is formed in the fixed sleeve 1, and a recess 11 is provided on the fixed sleeve 1; the left end of the adjustment member 2 is provided with a first thread 22, the adjustment member 2 is arranged in the installation channel, and the adjustment member 2 and the installation channel can slide relatively left and right; the right end of the push rod 3 is provided with a second thread, the first thread 22 and the second thread are matched and connected with each other, the right end of the push rod 3 is restricted in the installation channel, the left end of the push rod 3 can extend out from the left end of the installation channel, and a protrusion 31 adapted to the recess 11 is provided on the push rod 3; the spring 4 is arranged in the installation channel, the right end of the spring 4 is connected with the fixed sleeve 1, the left end of the spring 4 is connected with the adjustment member 2, and the adjustment member 2 is arranged between the spring 4 and the push rod 3; the spring 4 is used to provide elastic force to make the push rod 3 abut against the fixed sleeve 1, so that when the push rod 3 rotates relative to the fixed sleeve 1, the protrusion 31 enters or disengages from the recess 11.

[0031] As can be seen from the above, when the operator adjusts the extension length of the push rod 3 in the fixed sleeve 1, by rotating the push rod 3, a relative rotation is generated between the push rod 3 and the adjustment member 2. Since the adjustment member 2 is designed to be only able to slide relatively left and right with respect to the installation channel in the fixed sleeve 1 and cannot rotate relative to it, therefore, under the tight cooperation of the first thread 22 and the second thread, the extension length of the push rod 3 is accurately adjusted. It should be noted that this sliding design between the adjustment member 2 and the installation channel, combined with the elastic force of the spring 4, enables the adjustment member 2 to automatically drive the push rod 3 to move to the leftmost end when there is no external force, ensuring that the push rod 3 tightly abuts against the fixed sleeve 1. The protrusion 31 provided on the push rod 3 is adapted to the recess 11 on the fixed sleeve 1. When the operator rotates the push rod 3, a relative movement will occur between the protrusion 31 and the recess 11. If the protrusion 31 successfully enters the recess 11 or smoothly disengages from the recess 11, the operator will clearly feel a sense of jerk. This feedback mechanism enables the operator to clearly understand the number of turns or angles of rotation of the push rod 3, thus greatly improving the accuracy and efficiency of adjustment.

[0032] Compared with the threaded connection adjustment method commonly used in the traditional market, the adjustment structure provided by the present utility model is more convenient and intuitive in operation. It effectively solves the problem that it is difficult for the operator to accurately master the number of turns of rotation, avoids the cumbersome process of repeated attempts and adjustments, and significantly reduces the complexity and time cost of operation. Therefore, this adjustment structure has a wide range of application prospects in occasions such as door panel rebounders that require precise length adjustment.

[0033] During assembly, it is necessary to install components such as spring 4, adjusting member 2, and ejector rod 3 into the installation channel. To facilitate the installation of these components, in one embodiment, the fixed sleeve 1 includes a sleeve body 14 and a sealing cover 13. The sleeve body 14 defines the installation channel therein, and the sealing cover 13 is fixed to the fixed sleeve 1. The sealing cover 13 covers the right end of the installation channel, and the right end of the spring 4 abuts against the sealing cover 13. Specifically, the fixed sleeve 1 is composed of two parts, namely the sleeve body 14 and the sealing cover 13. The sleeve body 14 constructs an installation channel inside to accommodate these key components. The sealing cover 13 is tightly fixed on the fixed sleeve 1, and its design cleverly covers the right end of the installation channel, ensuring the integrity and sealing of the internal structure. During installation, the adjusting member 2 and the ejector rod 3 can be installed into the installation channel. Additionally, the spring 4 is placed inside the installation channel, and its right end is ensured to closely adhere to the sealing cover 13, which can not only provide stable elastic support but also maintain the compactness of the overall structure. This design not only simplifies the assembly process but also improves the installation efficiency, and it is very convenient for installation and disassembly, simplifying the subsequent maintenance process.

[0034] In actual use, a first pin hole is formed on the side surface of the sleeve body 14, and a second pin hole is formed on the sealing cover 13. The first pin hole and the second pin hole are connected by a pin to achieve the fixed connection between the sealing cover 13 and the sleeve body 14.

[0035] The adjusting member 2 can only slide left and right within the installation channel, restricting the relative rotation between the adjusting member 2 and the installation channel to ensure that relative rotation can occur between the first thread 22 and the second thread, and the angle of their relative rotation is accurate. In one embodiment, a chute 12 extending in the left-right direction is provided on the inner wall of the installation channel, and a slider 21 extends from the adjusting member 2. The slider 21 is inserted into the chute 12, and the slider 21 and the chute 12 can slide relatively left and right.

[0036] The adjusting member 2 is designed to be slidable only in the left - right direction within the installation channel, and such a design ingeniously restricts the relative rotation between the adjusting member 2 and the installation channel. This is to ensure that the relative rotation between the first thread 22 and the second thread can occur accurately, so as to achieve the purpose of precise adjustment. To achieve this function, sliding grooves 12 extending in the left - right direction are specially provided on the inner wall of the installation channel. These sliding grooves 12 are like tailor - made tracks for the sliders 21 on the adjusting member 2, enabling the sliders 21 to smoothly insert into them and slide left and right along the direction of the sliding grooves 12. At the same time, this design of concave - convex fit also effectively prevents the relative rotation between the adjusting member 2 and the installation channel, ensuring the accuracy and stability of the adjustment. In practical applications, to further enhance this restrictive effect, multiple sliding grooves 12, such as four, are usually provided. Correspondingly, the adjusting member 2 also extends out sliders 21 equal in number to the sliding grooves 12 to ensure that the adjusting member 2 can slide stably and accurately within the installation channel.

[0037] The left end of the ejector rod 3 extends out from the left end of the installation channel, and its right end is restricted by the fixed sleeve 1. When the operator causes the ejector rod 3 to rotate relative to the fixed sleeve 1, if the protrusion 31 on the ejector rod 3 can smoothly enter the recess 11 of the limit step in the installation channel or successfully disengage from the recess 11, they will clearly feel a sense of jerk. In one embodiment, the ejector rod 3 includes a rod body 32 and a shoulder 33 provided on the rod body 32. The protrusion 31 is provided on the left - end face of the shoulder 33. The inner wall of the installation channel extends a limit step, the aperture at the limit step is smaller than the outer diameter of the shoulder 33, and the recess 11 is provided on the right - end face of the limit step. This design ingeniously utilizes the structures of the limit step and the shoulder 33 to ensure that the ejector rod 3 does not completely slide out from the left end of the installation channel and at the same time provides clear feedback during operation. Specifically, the ejector rod 3 is mainly composed of a rod body 32 and a shoulder 33. The shoulder 33 is usually located at the right end or near the right end of the rod body 32, and the protrusion 31 is provided on the shoulder 33. The inner wall of the installation channel extends a limit step, and the aperture surrounded by the limit step is smaller than the outer diameter of the shoulder 33, thus playing a role in restricting the leftward movement of the shoulder 33 on the ejector rod 3. The recess 11 is provided on the right - end face of the limit step, corresponding to the protrusion 31 on the shoulder 33. Through the interaction between the protrusion 31 and the recess 11, clear operation feedback is provided to the operator.

[0038] In addition, in actual use, to ensure that the protrusion 31 can smoothly enter and disengage from the recess 11, the corners of the protrusion 31 and the recess 11 are designed with smooth transitions. Such treatment not only reduces wear but also improves the smoothness and comfort of operation.

[0039] The ejector rod 3 and the adjusting member 2 are connected by the cooperation of the first thread 22 and the second thread. In one embodiment, a threaded hole is formed in the right end face of the ejector rod 3, and the thread of the threaded hole is the second thread. The connection between the ejector rod 3 and the adjusting member 2 is realized through the close fit of the first thread 22 and the second thread. This design is not only simple in structure but also very convenient to install. Specifically, a threaded hole is formed in the right end face of the ejector rod 3, and the thread of this threaded hole is called the second thread. The first thread 22 on the adjusting member 2, that is, the first thread 22 is an external thread, and the first thread 22 cooperates with the second thread in this threaded hole to realize the firm connection between the two. In a certain embodiment, the threaded hole is formed in the right end face of the rod body 32.

[0040] Of course, this is only one of the embodiments. In actual operation, we can also make flexible adjustments according to specific requirements. For example, we can form the threaded hole on the adjusting member 2. At this time, the first thread 22 on the adjusting member 2 becomes an internal thread, and the second thread on the ejector rod 3 becomes an external thread accordingly, and the two can still be connected through the close fit of the threads.

[0041] When the protrusion 31 enters or leaves the recess 11, it provides a clear sense of jerk for the operator. This design enables the operator to intuitively perceive the number of turns or angles that the ejector rod 3 rotates relative to the fixed sleeve 1. In one embodiment, a plurality of the recesses 11 are provided, and the recesses 11 are arranged in a circumferential array centered on the axis of the fixed sleeve 1. A plurality of the protrusions 31 are provided, and the recesses 11 and the protrusions 31 are arranged in one-to-one correspondence. By arranging a plurality of the recesses 11 and the protrusions 31, a distinct sense of jerk can be generated within a rotation range of less than 360°, thereby significantly improving the operation accuracy. Specifically, these recesses 11 are arranged in a circumferential array centered on the axis of the fixed sleeve 1, and the protrusions 31 are arranged in one-to-one correspondence with the recesses 11 to ensure smooth and precise operation.

[0042] The present utility model also provides a rebounder, which includes a base 5 and the adjusting structure in any of the above embodiments, and the fixed sleeve 1 is fixed on the base 5. Through the arrangement of the base 5, the operator can easily install the base 5 on the side surface, the inner top surface or the inner bottom surface of the cabinet. This installation method is not only simple and fast but also greatly improves the flexibility of use.

[0043] Since the above content has elaborated on the adjusting structure, those skilled in the art should be able to understand it in combination with the accompanying drawings of the specification, so the adjusting structure will not be elaborated here anymore.

[0044] When the ejector is in use, after the ejector rod 3 is pressed to a certain depth and enters the fixed sleeve 1, it will encounter a limiting mechanism, which causes it to be unable to pop out by itself. In order to restore the rebound function of the ejector rod 3, the user needs to apply a pressing action to the ejector rod 3 again. This operation will release the limit on it, enabling the ejector rod 3 to pop out smoothly again. This design ensures the stability and controllability of the ejector during use. In one embodiment, the ejector further includes a hanging nail 61, a connecting shaft 63 and a tail piece 62. The tail piece 62 is fixed on the fixed sleeve 1. The connecting shaft 63 extends in the front-back direction. The connecting shaft 63 is fixed on the tail piece 62. The right end of the hanging nail 61 is provided in a ring shape. The ring-shaped right end of the hanging nail 61 is sleeved on the connecting shaft 63. The hanging nail 61 and the connecting shaft 63 can rotate relative to each other. The adjusting member 2 is used to limit and guide the hanging nail 61 so that the hanging nail 61 is restricted on the adjusting member 2 or disengages from the adjusting member 2. The tail piece 62 is firmly fixed on the fixed sleeve 1, and the connecting shaft 63 extends along the front-back direction and is firmly connected to the tail piece 62. The right end of the hanging nail 61 is designed into a ring structure, and this ring part is cleverly sleeved on the connecting shaft 63, enabling relative rotation between the hanging nail 61 and the connecting shaft 63. The adjusting member 2 is responsible for precisely limiting and guiding the hanging nail 61 to ensure that the hanging nail 61 can stay stably in the set position or disengage from the adjusting member 2.

[0045] The hanging nail 61 is cleverly arranged on the connecting shaft 63, and they can rotate relative to each other. This design allows the hanging nail 61 to rotate flexibly around the connecting shaft 63 when it comes into contact with the adjusting member 2. When the ejector rod 3 is pressed to a certain depth and enters the fixed sleeve 1, it will encounter a limiting mechanism on the adjusting member 2, which will temporarily prevent the ejector rod 3 from popping out by itself, ensuring the stability and controllability of the operation. However, as long as the user applies an appropriate pressing force to the ejector rod 3 again, this limit can be released, enabling the ejector rod 3 to quickly and smoothly return to its original state.

[0046] To this end, the adjusting member 2 includes an adjusting block 23, a first guiding block 24, a second guiding block 25, a third guiding block 26 and a fourth guiding block 27. The adjusting block 23 is slidable left and right between the installation channels. A counterbore is provided on the front side of the adjusting block 23. The first guiding block 24, the second guiding block 25, the third guiding block 26 and the fourth guiding block 27 are all fixed on the counterbore. The second guiding block 25 is arranged in the middle of the front side of the adjusting block 23. A first guiding angle 251 is formed on the right side of the second guiding block 25, and the opening of the included angle of the first guiding angle 251 faces left. The first guiding block 24 is arranged on the right side of the second guiding block 25, and the right side surface of the first guiding block 24 is inclined. The lower end of the right side surface of the first guiding block 24 is located below the vertex of the first guiding angle 251, so that an inlet channel 28 is formed between the lower side surface of the first guiding block 24, the lower side surface of the second guiding block 25 and the lower side wall of the counterbore. The third guiding block 26 is arranged on the left side of the second guiding block 25, and the fourth guiding block 27 is arranged below the third guiding block 26. An intermediate channel 29 is formed between the fourth guiding block 27 and the third guiding block 26. The right side surface of the fourth guiding block 27 faces the inlet channel 28, and the right side surface of the fourth guiding block 27 is used to guide the hanging nail 61 into the intermediate channel 29. A second guiding angle 252 is formed on the left side surface of the second guiding block 25, and the opening of the included angle of the second guiding angle 252 faces left. The vertex of the second guiding angle 252 is located above the intermediate channel 29. An exit channel 210 is formed between the upper side surface of the third guiding block 26, the upper side surface of the second guiding block 25 and the upper side wall of the counterbore. The right side surface of the third guiding block 26 is inclined to guide the vertex of the second guiding angle 252 in the hanging nail 61 into the exit channel 210.

[0047] The adjusting member 2 is mainly composed of an adjusting block 23, a first guiding block 24, a second guiding block 25, a third guiding block 26 and a fourth guiding block 27, which are closely connected and work together. The adjusting block 23 can slide freely in the installation channel, and a counterbore is provided thereon to accommodate the first guiding block 24, the second guiding block 25, the third guiding block 26 and the fourth guiding block 27. The second guiding block 25 is located in the middle of the front side of the adjusting block 23, and a first guiding angle 251 formed on its right side faces left. The first guiding block 24 is adjacent to the right side of the second guiding block 25, and its right side is an inclined surface, which together with the second guiding block 25 and the lower side wall of the counterbore forms an inlet channel 28. The third guiding block 26 is located on the left side of the second guiding block 25, and the fourth guiding block 27 is located below it, and an intermediate channel 29 is formed between the two. The right side face of the fourth guiding block 27 faces the inlet channel 28 and is responsible for guiding the hanging pin 61 into the intermediate channel 29. A second guiding angle 252 formed on the left side face of the second guiding block 25 also faces left, and its vertex is located above the intermediate channel 29. The third guiding block 26, the second guiding block 25 and the upper side wall of the counterbore together form an exit channel 210, and the inclined design of its right side face helps to guide the hanging pin 61 to slide into the exit channel 210 from the vertex of the second guiding angle 252.

[0048] The rebounder has two states: extended and retracted. When the rebounder is in the extended state, if its ejector rod 3 is pushed into the fixed sleeve 1 by an external force, the first guiding block 24 will first contact the end of the hanging pin 61. Subsequently, under the guidance of the right side face of the first guiding block 24, the hanging pin 61 and the connecting shaft 63 will rotate relative to each other, causing the end of the hanging pin 61 to enter the channel 28. If the external force continues at this time, the end of the hanging pin 61 will abut against the fourth guiding block 27 and, under the guiding action of its right side face, further slide into the intermediate channel 29. When the end of the hanging pin 61 touches the left side wall of the counterbore, its movement limit is reached. At this time, if the external force is removed, the spring 4 will push the adjusting member 2 away from the hanging pin 61, causing the end of the hanging pin 61 to be stuck at the vertex of the second guiding angle 252, thus triggering the limiting mechanism to prevent the ejector rod 3 from automatically popping out.

[0049] Apply an external force to the ejector rod 3 again, forcing it to penetrate deeper into the fixed sleeve 1, and the adjusting member 2 will move towards the hanging pin 61. Under the guidance of the right side face of the third guiding block 26, the end of the hanging pin 61 will slide into the exit channel 210. As the external force continues, the end of the hanging pin 61 will finally abut against the left side wall of the counterbore, reaching another movement limit. At this time, if the external force is removed, the force of the spring 4 will cause the hanging pin 61 to smoothly exit along the exit channel 210.

[0050] In addition, in actual use, a first abutting block 81 can also be provided on the adjusting member 2, and a second abutting block 82 can be provided on the tail piece 62, and the two abut against each other to play a limiting role, so as to replace the end of the hanging pin 61 abutting against the left side wall of the counterbore as the movement limit.

[0051] It should be noted that the end of the above-mentioned hanging nail 61 refers to the left end of the hanging nail 61.

[0052] In one embodiment, the rebounder further includes a magnet block 7, a blind hole is formed at the left end of the push rod 3, and the magnet block 7 is disposed in the blind hole.

[0053] In actual use, the base 5 of the rebounder is generally installed on the inner side, inner top or inner bottom of the cabinet. In order to ensure that the cabinet door will not separate from the top rod 3 of the rebounder due to the elasticity of the material after contacting the rod body 32, the operator will install an iron block on the cabinet door. In this way, through the magnetic adsorption effect of the magnet block 7 and the iron block, the cabinet door can be effectively prevented from separating at the moment of colliding with the top rod 3 of the rebounder. The magnet block 7 is placed in the blind hole at the left end of the top rod 3 to achieve this function.

[0054] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
