Description

Technical Field

[0001] The invention relates to a position limiting and disassembling structure of a drawer panel. Background Art

[0002] The Chinese patent document number CN103584524B disclosed a locking and separation mechanism of a drawer panel on August 17, 2016, which includes an adjustment seat and an adjustment box body arranged in the drawer side panel, the drawer panel is connected to the adjustment seat or the adjustment box body through more than two connecting parts, wherein the adjustment box body is arranged on the adjustment seat, the adjustment seat or the adjustment box body is provided with a locking device, and a push-out device with an automatic reset function is provided corresponding to the locking device, and a tool acts on the action part of the push-out device and drives the swing rod of the locking device to move, so as to realize the disassembly and separation of the connecting part and the locking device; the push-out device realizes automatic reset through the cooperation of a tension spring and a steering member. It is said that the above mechanism is provided with a tension spring on the push-out device, and utilizes the movement of the tension spring around the steering member to realize automatic reset after the connecting part connected to the drawer panel is pushed out, which effectively increases the length of the tension spring and reduces the tension change of the tension spring, which is conducive to eliminating the phenomenon of asynchronism or jamming when the connecting part and the locking device are locked, and also saves the overall space of the product. However, in order to achieve the locking and separation of the panel, the above mechanism has a very complex structure, a large number of components, and high requirements for production and assembly processes. At the same time, if individual components are damaged, the entire mechanism cannot be used normally, and the damage and failure rate are quite high. In addition, the ejection device has no limit and is prone to displacement. The action part on the ejection device is also exposed and easy to be touched by the user, which further causes the ejection device to be easily displaced, resulting in the two connecting parts being unable to be locked on the locking device, causing the drawer panel to be separated for no reason, seriously affecting the user's experience. Therefore, further improvements are necessary. Summary of the invention

[0003] The purpose of the present invention is to provide a drawer panel limiting and disassembly structure with simple and reasonable structure, reliable performance, compact connection of components, low manufacturing cost, safe use, long service life, quick and convenient disassembly and assembly, and high flexibility, so as to overcome the shortcomings of the prior art.

[0004] A drawer panel limiting and disassembling structure designed for this purpose includes a connecting element and a fixing element, and is characterized in that: more than two connecting elements are provided; and more than two locking elements are provided on the fixing element.

[0005] The two or more locking elements are relatively independent and elastically rotate or swing at the upper and lower positions of the fixed element respectively, and are locked and separated from the two or more connecting elements respectively during elastic rotation or swinging to realize the disassembly and assembly of the connecting element on the fixed element.

[0006] The two or more locking elements are respectively provided with a disassembly action portion for being acted upon by a tool or manually, and for realizing separation of the locking element from the connecting element when acted upon by a tool or manually.

[0007] The fixing element is also elastically provided with more than two shielding parts for shielding at least a portion of the disassembly action part, and an anti-slipping part for preventing the locking element from being separated from the connecting element when locked.

[0008] The two or more shielding parts and the anti-slipping parts are arranged in one piece or separately and are independent of each other. The two or more shielding parts and the anti-slipping parts are elastically movable on the fixing elements respectively.

[0009] The fixing element is provided with an elastic movable part, which has a certain elasticity or plastic, and the middle part of the elastic movable part is fixedly provided on the fixing element, and the outer end is integrally provided with a shielding part and an anti-slipping part facing the direction of more than two locking elements; the shielding part and the anti-slipping part are elastically movable on the fixing element through the elasticity of the elastic movable part or the plastic.

[0010] The fixed element is provided with a movable part, and there are more than two movable parts. The more than two movable parts are relatively independently arranged and elastic parts are arranged between each other. The outer ends of the more than two movable parts are provided with shielding parts and anti-slipping parts in the direction of the more than two locking elements; the more than two movable parts are elastically moved on the fixed element respectively through the elastic parts; the shielding part and the anti-slipping part move together with the movable parts.

[0011] The two or more connecting elements are respectively provided with a clamping part; the two or more locking elements are respectively provided with a clamping fitting part, and the clamping parts of the two or more connecting elements are respectively clamped and released by the clamping fitting parts to realize the disassembly and assembly of the connecting element on the fixing element.

[0012] The two or more locking elements are respectively provided with anti-slipping parts; when the engaging fitting part is engaged with the engaging part, the locking element acts on the anti-slipping part through the anti-slipping part to prevent the locking element from being separated when being locked with the connecting element.

[0013] At least when the connecting element is assembled, the shielding portion shields at least a portion of the disassembly function portion, and the anti-slip function portion is limited to act on the anti-slip portion.

[0014] When the tool or manual operation is performed in the direction of the disassembly action part, the shielding part and the anti-slipping part are driven to move elastically. The shielding part avoids the disassembly action part during the elastic movement, and the anti-slipping part is separated from the anti-slipping action part during the elastic movement.

[0015] The tool or manual operation acts on the disassembly action portion when the shielding portion is avoided, and drives the locking element to rotate or swing on the fixing element. When the locking element rotates or swings, the snap-fitting portion and the snap-fitting portion are driven to separate from each other, so as to realize the disassembly between the connecting element and the fixing element.

[0016] The shielding portion and the anti-detachment portion are elastically reset to their initial positions respectively when the tool or manual operation leaves the disassembly action portion.

[0017] The two or more connecting elements slide synchronously or asynchronously toward the fixed element, and when sliding to a certain position, they synchronously or asynchronously drive the two or more locking elements to rotate or swing on the fixed element respectively. When rotating or swinging, the two or more locking elements are synchronously or asynchronously clamped on the clamping part through the clamping matching part, so as to realize synchronous or asynchronous assembly between the two or more connecting elements and the fixed element.

[0018] When the two or more connecting elements are assembled with the fixing element, the acting part is disassembled by means of a tool or manual action, and the two or more locking elements are driven to rotate or swing on the fixing element respectively. When the two or more locking elements rotate or swing, the snap-fitting matching part and the snap-fitting part are driven to separate from each other, so as to realize the separate disassembly between the two or more connecting elements and the fixing element.

[0019] The more than two connecting elements are at least a first connecting element and a second connecting element; the more than two locking elements are at least a first locking element and a second locking element, and an elastic member is arranged between the first locking element and the second locking element; one end of the elastic member elastically rotates on the first locking element, and the other end elastically rotates on the second locking element.

[0020] The first locking element is elastically rotated or swung on the fixing element through an elastic member, and is locked and separated from the first connecting element during the elastic rotation or swing.

[0021] The second locking element is elastically rotated or swung on the fixing element through an elastic member, and is locked and separated from the second connecting element during the elastic rotation or swing.

[0022] In which, at least when the first locking element and the first connecting element are separated, the second locking element is elastically positioned on the fixing element by the elastic member, and its position remains basically unchanged; and / or, at least when the second locking element and the second connecting element are separated, the first locking element is elastically positioned on the fixing element by the elastic member, and its position remains basically unchanged.

[0023] The fixing element is provided with guide grooves, and there are more than two guide grooves. The more than two guide grooves are relatively independent and are respectively arranged at the upper and lower positions of the fixing element; the more than two connecting elements are respectively guided and slid on the more than two guide grooves in a gap-like manner, and are respectively locked and separated with the more than two locking elements when sliding.

[0024] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0025] 1. By using only two or more locking elements and elastic parts, it is possible to realize the disassembly and assembly of two or more connecting elements on the fixing elements, thereby effectively simplifying the disassembly and assembly structure between the connecting elements and the fixing elements, thereby avoiding a series of problems in the prior art such as the complex disassembly and assembly structure of the drawer panel, the large number of components, the high requirements for production and assembly processes, the poor stability of the entire structure, the high damage and failure rate, etc., making the disassembly and assembly of the drawer panel more stable and reliable.

[0026] 2. Two or more connecting elements can be locked onto two or more locking elements synchronously or asynchronously, and they can be disassembled individually without interfering with each other, thereby making the disassembly and assembly of the drawer panel more flexible and more convenient and quick.

[0027] 3. Use the shielding part to shield at least part of the disassembly action part to prevent the disassembly action part from being exposed and easily touched by users or foreign objects, causing user injuries, or separation of the locking element and the connecting element after being locked, making it safer for users to use and more stable for the locking between the locking element and the connecting element.

[0028] 4. The anti-slip portion is used to limit the position of the locking element, thereby avoiding displacement of the locking element and the connecting element when they are locked, which may cause the two to separate, and further ensure that the locking element and the connecting element can achieve stable locking cooperation.

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] First embodiment

[0042] See also Figure 1-Figure 15 The limiting disassembly and assembly structure of the drawer panel includes a side panel 18, a drawer panel, a connecting element and a fixing element 1.

[0043] There are more than two connecting elements, which are fixedly connected to the drawer panels respectively; the front end of the side panel 18 is provided with a mounting groove 19; the fixing element 1 is fixedly arranged on the mounting groove 19, and there are more than two locking elements for locking and separating the connecting elements.

[0044] The two or more locking elements are relatively independent and elastically rotate or swing at the upper and lower positions of the fixed element 1, and are locked and separated from the two or more connecting elements respectively during the elastic rotation or swing, so as to realize the disassembly and assembly of the connecting elements on the fixed element 1.

[0045] The two or more locking elements are respectively provided with a disassembly action portion 11 for being acted upon by a tool X or manually, and for realizing separation of the locking element from the connecting element when the tool X or manually acts.

[0046] The fixing element 1 also has two or more elastic shielding parts 15 for shielding at least a portion of the disassembly action part 11, and an anti-slip part 16 for preventing the locking element from being separated from the connecting element when locked.

[0047] The shielding portion 15 is used to shield at least a portion of the disassembly function portion 11 to prevent the disassembly function portion 11 from being exposed and easily touched by a user or a foreign object, thereby preventing the user from being injured or the locking element and the connecting element from separating after being locked. This makes the user's use safer and the locking between the locking element and the connecting element more stable.

[0048] The anti-slip portion 16 is used to limit the position of the locking element, thereby avoiding displacement of the locking element and the connecting element when they are locked (i.e. rotation or swinging due to external force), which would cause the two to separate, and further ensure that a stable locking fit can be achieved between the locking element and the connecting element.

[0049] Specifically, the two or more shielding parts 15 and the anti-slipping parts 16 are integrally or separately arranged and independent of each other, and the two or more shielding parts 15 and the anti-slipping parts 16 are elastically movable on the fixing element 1 respectively.

[0050] In this embodiment, more than two shielding parts 15 and anti-slipping parts 16 are integrally arranged. That is, an elastic movable part 20 is arranged on the fixing element 1. The elastic movable part 20 has a certain elasticity or plastic, and the middle part is fixedly arranged on the fixing element 1, and the outer end is integrally arranged with the shielding part 15 and the anti-slipping part 16 in the direction of more than two locking elements; the shielding part 15 and the anti-slipping part 16 are elastically movable on the fixing element 1 by the elasticity of the elastic movable part 20 or the plastic elasticity.

[0051] The elastic movable member 20 of this embodiment is actually a spring sheet, the center of which is provided on the fixing element 1, and the two outer ends thereof are integrally provided with a shielding portion 15 and an anti-slip portion 16 in the direction of more than two locking elements.

[0052] A clamping portion 10 is provided on two or more connecting elements respectively; a clamping fitting portion 12 is provided on the two or more locking elements respectively, and the clamping portions 10 of the two or more connecting elements are respectively clamped and released by the clamping fitting portions 12 to realize the disassembly and assembly of the connecting elements on the fixing element 1.

[0053] Two or more locking elements are respectively provided with anti-slipping parts 23; when the engaging fitting part 12 is engaged with the engaging part 10, the locking element is limited to act on the anti-slipping part 16 through the anti-slipping part 23 to prevent the locking element from separating when being locked with the connecting element.

[0054] At least when the connecting element is assembled, the shielding portion 15 shields at least a portion of the disassembly function portion 11 , and the anti-detachment function portion 23 acts on the anti-detachment function portion 16 .

[0055] like Fig.10 , Fig.11 As shown, when the connecting element is assembled on the fixing element 1, the shielding portion 15 will shield at least part of the disassembly action portion 11 in a natural state, and the anti-detachment portion 16 will limit the anti-detachment action portion 23 in a natural state. That is, when the connecting element is disengaged to the outside, the anti-detachment portion 16 will limit the anti-detachment action portion 23 to prevent the locking element from rotating or swinging on the fixing element 1 again, and the locking element will not have any displacement phenomenon, thereby preventing the problem of separation when the snap-fitting portion 12 is locked with the snap-fitting portion 10, avoiding the problem of the drawer panel being separated from the side plate 18 for no reason, and improving the safety of use.

[0056] like Figure 12-Figure 15 As shown, the user uses tool X to act on the shielding portion 15 to avoid exposing the disassembly portion 11, so that the tool X can act on the disassembly portion 11, and at the same time, the anti-detachment portion 16 is driven to separate from the clamping portion 10, thereby reducing the problem of user's misoperation.

[0057] That is, when the tool X acts in the direction of the disassembly portion 11 , the shielding portion 15 and the anti-detachment portion 16 are driven to move elastically. The shielding portion 15 avoids the disassembly portion 11 during the elastic movement, and the anti-detachment portion 16 is separated from the anti-detachment portion 23 during the elastic movement.

[0058] When the shielding portion 15 is evaded, the tool X acts on the disassembly acting portion 11 and drives the locking element to rotate or swing on the fixing element 1. When the locking element rotates or swings, the snap-fitting portion 12 and the snap-fitting portion 10 are separated from each other to realize the disassembly between the connecting element and the fixing element 1.

[0059] The shielding portion 15 and the anti-detachment portion 16 are elastically reset to their initial positions respectively when the tool X or manual operation leaves the disassembly action portion 11 .

[0060] like Figure 6-Figure 8 As shown in the sequence, more than two connecting elements synchronously slide toward the fixing element 1, and when sliding to a certain position, more than two locking elements are synchronously driven to rotate or swing on the fixing element 1 respectively. When rotating or swinging, the more than two locking elements are synchronously clamped on the clamping part 10 through the clamping fitting part 12 respectively, so as to realize the synchronous assembly between the more than two connecting elements and the fixing element 1.

[0061] Or, if Figure 6 , Figure 7 , Fig. 9As shown in the sequence, more than two connecting elements slide toward the fixed element 1 asynchronously, and when sliding to a certain position, they asynchronously drive more than two locking elements to rotate or swing on the fixed element 1 respectively. When rotating or swinging, the more than two locking elements are asynchronously clamped on the clamping part 10 by the clamping fitting part 12 respectively, so as to realize the asynchronous assembly between the more than two connecting elements and the fixed element 1.

[0062] like Figure 12-Figure 15 As shown in the sequence, when two or more connecting elements are assembled with the fixing element 1, the action portion 11 is disassembled by means of a tool X or manual action, and the two or more locking elements are driven to rotate or swing on the fixing element 1 respectively. When the two or more locking elements rotate or swing, the snap-fitting portion 12 and the snap-fitting portion 10 are driven to separate from each other, so as to realize the separate disassembly between the two or more connecting elements and the fixing element 1.

[0063] The above-mentioned two or more connecting elements are at least the first connecting element 3 and the second connecting element 4; the above-mentioned two or more locking elements are at least the first locking element 5 and the second locking element 6, and an elastic member 2 is arranged between the first locking element 5 and the second locking element 6; one end of the elastic member 2 elastically rotates on the first locking element 5, and the other end elastically rotates on the second locking element 6.

[0064] The first locking element 5 is elastically rotated or swung on the fixing element 1 by the elastic member 2, and is locked with and separated from the first connecting element 3 during the elastic rotation or swing.

[0065] The second locking element 6 is elastically rotated or swung on the fixing element 1 by the elastic member 2, and is locked with and separated from the second connecting element 4 during the elastic rotation or swing.

[0066] Among them, at least when the first locking element 5 and the first connecting element 3 are separated, the second locking element 6 is elastically positioned on the fixing element 1 by the elastic member 2, and its position remains basically unchanged; and / or, at least when the second locking element 6 and the second connecting element 4 are separated, the first locking element 5 is elastically positioned on the fixing element 1 by the elastic member 2, and its position remains basically unchanged.

[0067] That is to say, it is explained that the separation between the first locking element 5 and the first connecting element 3 and the separation between the second locking element 6 and the second connecting element 4 do not interfere with each other and can be operated independently.

[0068] Specifically, the tool X acts on the first locking element 5 to separate it from the first connecting element 3, and at this time, the front-back, top-bottom and left-right positions of the second locking element 6 on the fixing element 1 remain substantially unchanged; the tool X acts on the second locking element 6 again to separate it from the second connecting element 4, and at this time, the front-back, top-bottom and left-right positions of the first locking element 5 on the fixing element 1 remain substantially unchanged. This effectively avoids the problem that the drawer panel is locked twice after being unlocked and causes collisions due to the forces of multiple locking elements during disassembly, which makes it difficult for users to disassemble the drawer panel; compared with the prior art, the assembly steps and manufacturing tolerances between components are effectively reduced, thereby preventing operators from operating incorrectly, and further making the disassembly and assembly of the drawer panel faster and more convenient, and the user can also arbitrarily increase the number of locking elements according to the height of the drawer panel, so that it can be widely used in the installation and use of large and medium-sized front panels, and the user only needs to twist the tool X to realize the separation of multiple locking elements from different connecting elements in sequence, which is highly practical.

[0069] Since only more than two locking elements and the elastic member 2 are used, more than two connecting elements can be disassembled and assembled on the fixing element 1, thereby effectively simplifying the disassembly and assembly structure between the connecting element and the fixing element 1, thereby avoiding a series of problems in the prior art such as complex disassembly and assembly structure of the drawer panel, a large number of components, high requirements for production and assembly process, poor stability of the entire structure, high damage and failure rate, etc., making the disassembly and assembly of the drawer panel more stable and reliable.

[0070] Furthermore, a first rotational action portion A is formed between one end of the elastic member 2 and the first locking element 5, and the two are elastically rotationally connected to each other through the first rotational action portion A; a second rotational action portion B is formed between the other end of the elastic member 2 and the second locking element 6, and the two are elastically rotationally connected to each other through the second rotational action portion B.

[0071] At least when the connecting element is disassembled, the first locking element 5 rotates or swings on the fixed element 1, and drives the elastic member 2 through the first rotation action portion A to rotate or swing with the first locking element 5 with the second rotation action portion B as the action point; and / or, the second locking element 6 rotates or swings on the fixed element 1, and drives the elastic member 2 through the second rotation action portion B to rotate or swing with the first rotation action portion A as the action point.

[0072] There is only one elastic member 2 between the first locking element 5 and the second locking element 6 , that is, the first locking element 5 and the second locking element 6 are elastically rotated or swung at upper and lower positions of the fixing element 1 through separate and common elastic members 2 .

[0073] In order to make the elasticity of the elastic member 2 more accurate, a guide assembly is further arranged between the first locking element 5 and the second locking element 6, and the guide assembly includes a first guide member 7 and a second guide member 8 that guide and cooperate with each other; the first guide member 7 is rotatably arranged on the first locking element 5, and a first rotation action portion A is formed between them; the second guide member 8 is rotatably arranged on the second locking element 6, and a second rotation action portion B is formed between them; the elastic member 2 is a compression spring, and is sleeved between the first guide member 7 and the second guide member 8, and elastically acts on the first guide member 7 and the second guide member 8 respectively, so as to realize that the elastic member 2 always generates an elastic force in the direction of the first locking element 5 and the second locking element 6 respectively.

[0074] Furthermore, an intermediate guide member 9 is provided between the first guide member 7 and the second guide member 8 , and the intermediate guide member 9 is telescopically sleeved on the first guide member 7 and the second guide member 8 , respectively, to achieve mutual fit between the first guide member 7 and the second guide member 8 .

[0075] That is, the elastic member 2 can be movably mounted on the first guide member 7, the second guide member 8, and the intermediate guide member 9, so that the elastic force generated by the elastic member 2 can be more concentrated, and the problem of deformation or flying off caused by the elastic force generated and when it rotates or swings with the first locking element 5 and / or the second locking element 6 can be reduced, making the assembly of the elastic member 2 more stable.

[0076] The two or more connecting elements are integrally or separately arranged, and are independent of each other, and a certain distance is formed between them. In this embodiment, the two or more connecting elements are integrally arranged and fixedly arranged on the drawer panel. The two or more connecting elements are respectively locked and matched with the two or more locking elements synchronously or asynchronously.

[0077] The fixing element 1 is provided with a guide groove 13, and there are more than two guide grooves 13. The more than two guide grooves 13 are relatively independent and are respectively provided at the upper and lower positions of the fixing element 1; the more than two connecting elements are respectively guided and slid in the more than two guide grooves 13 in a gap-like manner, and are respectively locked and separated with the more than two locking elements when sliding.

[0078] The above-mentioned more than two guide grooves 13 have a guiding function and are clearance-matched with more than two connecting elements respectively, so that the more than two connecting elements can be stably locked and separated with more than two locking elements, avoiding the problem of left and right shaking, up and down jumping, or locking and separation difficulties of more than two connecting elements after assembly, thereby improving the user experience.

[0079] Second embodiment

[0080] See also Figure 16-Figure 19The limiting disassembly structure of the drawer panel is different from the first embodiment in that: a movable part 21 is arranged on the fixed element 1, and more than two movable parts 21 are arranged, the more than two movable parts 21 are arranged relatively independently, and elastic parts 22 are arranged between each other, and the outer ends of the more than two movable parts 21 are provided with shielding parts 15 and anti-slipping parts 16 in the direction of the more than two locking elements; the more than two movable parts 21 are elastically movable on the fixed element 1 respectively through the elastic parts 22; the shielding part 15 and the anti-slipping part 16 move together with the movable part 21.
