Description

Technical Field

[0001] This invention relates to the field of fastening components, specifically to a quick-release fastening component, hinge, handle, and door lock. Background Technology

[0002] Fastening components are commonly used to connect various hardware accessories such as hinges, handles, and door locks to various doors, cabinets, windows, boxes, tool kits, and other installation objects. For example, they are used to connect handles to cabinets, hinges to door panels, and door locks to door panels.

[0003] Existing fastening assemblies typically include a base, a groove disposed on the base, two fastening elements slidably disposed in the groove, and a compression spring. See attached patent application CN1914395B. Figure 1 Two fastening elements can slide towards each other or away from each other along the groove. A receiving groove is formed between the fastening bevel and the base, allowing the opening edge to extend into it. The fastening bevel presses against the opening end face, thus restricting and fixing the opening edge within the receiving groove. When the fastening assembly is inserted into the opening, the large bevel of the fastening assembly is pressed against the opening edge. The two fastening elements slide towards each other under pressure until the large bevel passes through the opening, and the opening edge is engaged in the receiving groove. The two fastening elements then move away from each other under the action of the compression spring until the fastening bevel presses against the opening edge, thereby restricting and fixing the opening edge within the receiving groove. This allows for the rapid installation of various hinges, handles, and door locks, replacing screws.

[0004] However, with this installation method, after the fastening assembly is installed, the fastening bevel needs to maintain a certain compressive force to press against the inner side of the opening. When unlocking or pulling the door handle or shaking the hinge, slight slippage can easily occur between the fastening bevel and the opening, resulting in some sliding friction. (See attached...) Figure 1 It is evident from the image that the fastening bevel in patent application CN1914395B only contacts the corner of the opening. When the base is pulled, the fastening bevel cannot contact the plane of the opening edge; it only contacts the corner of the opening. The compression contact surface during pulling is merely a thin, elongated contact surface resembling a straight line, referred to here as linear contact. The linear contact area is shown in the attached image. Figure 1 As shown. When the base is pulled, the linear contact structure of the fastening ramp and the opening leads to unstable clamping effect of the fastening components, thus reducing the clamping effect.

[0005] This application provides a quick-release fastening assembly to overcome the above-mentioned technical problems. Summary of the Invention

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a quick-installation fastening component. This quick-installation fastening component is quick and convenient to install. It is assembled and fixed by having the stepped surface and the assembly plane contact the back and front surfaces of the opening edge, respectively. It has a large contact area, good clamping stability, excellent clamping effect, and is not easy to loosen.

[0007] The objective of this invention is achieved through the following technical solution: a quick-installation fastening assembly, including a base;

[0008] The base is provided with an assembly surface;

[0009] The assembly is fixed to the assembly plane;

[0010] A sliding groove is provided through the assembly;

[0011] Two sliders are symmetrically arranged within the groove, and the two sliders can slide towards each other or move away from each other along the groove;

[0012] A compression spring, clamped between the two sliders, is used to keep the two sliders in a distance from each other.

[0013] A stepped surface is provided on the slider and located on the surface of the slider opposite to the base;

[0014] A receiving groove is formed between the stepped surface and the mounting plane when the two sliders are in a distanced state, for receiving the edge of the opening.

[0015] The quick-install door lock also includes two sets of limiting components, which are used to prevent the two sliders from sliding off the slide groove.

[0016] The limiting component includes a limiting member and a limiting groove;

[0017] A limiting groove is formed in the assembly;

[0018] The limiting component has one end fixed to the slider and the other end inserted into the limiting groove and can move with the slider within the limiting groove.

[0019] The limiting component is a nut screw, one end of which is screwed to the slider, and the other end is inserted into the limiting groove.

[0020] The groove is a V-shaped groove, and the minimum angle between the V-shaped groove and the horizontal plane is 5°-40°.

[0021] As a preferred option in this application, the minimum angle between the V-groove and the horizontal plane is 10°.

[0022] The slider has two inclined surfaces, which are formed on the upper and lower end surfaces of the slider, respectively, and the two inclined surfaces are sliding surfaces.

[0023] The slider has an arc-shaped surface, which is formed on the outer end face of the slider.

[0024] The slider is provided with two sliding extension blocks. The upper end face of one sliding extension block is flush with the upper end face of the slider, and both the slider and the upper end face of the sliding extension block are slidably in contact with the upper wall of the groove. The lower end face of the other sliding extension block is flush with the lower end face of the slider, and both the sliding extension block and the lower end face of the slider are slidably in contact with the lower wall of the groove.

[0025] The slider has a spring position located on the opposite side of the two sliders, which is used to connect one end of the compression spring.

[0026] A quick-release hinge includes two quick-release fastening components as described above, wherein the base of one quick-release fastening component serves as the fixed page of the quick-release hinge, and the base of the other quick-release fastening component serves as the movable page of the quick-release hinge, wherein the fixed page and the movable page are hinged together.

[0027] A quick-release handle includes a quick-release fastening assembly as described above, wherein the base of the quick-release fastening assembly serves as the handle body.

[0028] A quick-install door lock includes a quick-install fastening assembly as described above. The base serves as the main body of the door lock and further includes a hook disposed on the mounting plane of the main body of the door lock, with a groove formed between the hook and the mounting plane for the opening edge of the door panel to engage.

[0029] In the actual assembly process of the quick-installation fastening assembly of this application, the assembly is pushed into the opening. During the pushing process, the two sliders are squeezed by the inner wall of the opening and slide towards each other along the slide groove, compressing the compression spring. Thus, the sliders make way for the space for the edge of the opening to enter the receiving groove. After the assembly is pushed into place, the edge of the opening enters the receiving groove, and the inner wall of the opening no longer squeezes the sliders. The compression spring releases its elastic force and pushes the two sliders to slide along the slide groove in opposite directions to return to the initial position. The sliders complete the reset, and the edge of the opening is restricted in the receiving groove. The front and back surfaces of the edge of the opening abut against the assembly plane and the step surface, respectively, to achieve surface contact clamping of the edge of the opening, thereby completing the fastening installation of the fastening assembly.

[0030] The beneficial effects of this invention are as follows: After the slider is reset, the front end face of the opening edge abuts against the mounting plane of the base, and the rear end face of the opening edge abuts against the stepped surface, quickly completing the connection between the quick-release fastening component and the opening without the need for screw fixation. After installation, the quick-release fastening component is fixed by the abutment of the stepped surface and the mounting plane of the base against the rear end face and the front end face of the opening edge, respectively, achieving surface contact clamping of the opening edge and completing the fastening installation of the fastening component. During subsequent use, pulling the quick-release fastening component will not cause sliding friction between the inner wall surface of the opening and the clamping contact surface of the slider, preventing wear on the inner wall surface of the opening and the slider, and preventing scratches on the stepped surface at the opening corners. Even after long-term use, the opening edge and the quick-release fastening component of this application maintain good assembly accuracy without significant loosening, significantly increasing the service life of the slider and the opening edge, improving the clamping stability and clamping effect of the quick-release fastening component of this application, resulting in excellent clamping effect, good clamping stability, and resistance to loosening. The slider in this application does not require continuous pressure to press against the inner wall of the opening, nor does it require a strong elastic component. Only a spring with a small elastic force is needed to provide a restoring force for the slider's reset movement. The mounting plane of the step surface and the base uses a planar contact method with the back and front surfaces of the opening edge. The large clamping contact area improves the clamping stability and clamping effect of the quick-release fastening component of this application. It has a good clamping effect and good clamping stability, and is not easy to loosen, unlike the linear contact method of patent application CN1914395B, which has a small contact area and unstable clamping effect, thus reducing the clamping effect and making it easy to loosen. After the quick-release fastening component of this application is assembled, the corners of the opening will not press against the clamping contact surface of the step surface, and will not damage the step surface. There will be no frictional wear between the opening edge, the step surface, and the mounting plane, which can maintain good assembly accuracy for a long time and is not easy to loosen, further improving the clamping stability and clamping effect.

Detailed Implementation

[0042] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figures 1-10 The present invention will be further described below, and the content mentioned in the embodiments is not intended to limit the present invention.

[0043] See Figures 2-6 A quick-release fastening assembly includes a base 1;

[0044] The base is provided with an assembly surface 20;

[0045] Assembly 4 is fixed to the assembly plane 20;

[0046] The slide groove 5 is provided through the assembly 4;

[0047] Two sliders 6 are symmetrically arranged within the groove 5. The two sliders 6 can slide towards each other or move away from each other along the groove 5.

[0048] A compression spring 7 is clamped between the two sliders 6 to keep the two sliders 6 in a distance from each other;

[0049] Step surface 8 is disposed on the slider 6 and located on the surface of the slider 6 opposite to the base 1;

[0050] The receiving groove 9 is formed between the stepped surface 8 and the mounting plane 20 when the two sliders 6 are in a far apart state, and is used to receive the edge of the door panel.

[0051] In the actual assembly process of the quick-installation fastening assembly of the present invention, the assembly is pushed into the opening. During the pushing process, the two sliders are squeezed by the inner wall of the opening and slide towards each other along the slide groove and compress the compression spring. Thus, the sliders make way for the space for the edge of the opening to enter the receiving groove. After the assembly is pushed into place, the edge of the opening enters the receiving groove, and the inner wall of the opening no longer squeezes the sliders. The compression spring releases its elastic force and pushes the two sliders to slide along the slide groove in opposite directions to return to the initial position. The sliders complete the reset, and the edge of the opening is restricted in the receiving groove. The front end and back end of the edge of the opening abut against the assembly plane and the step surface of the base, respectively, to achieve surface contact clamping of the edge of the opening, thereby completing the fastening installation of the fastening assembly.

[0052] The beneficial effects of this invention are as follows: After the slider is reset, the front end face of the opening edge abuts against the mounting plane of the base, and the rear end face of the opening edge abuts against the stepped surface, quickly completing the connection between the quick-release fastening component and the opening without the need for screw fixation. After installation, the quick-release fastening component is fixed by the abutment of the stepped surface and the mounting plane of the base against the rear end face and the front end face of the opening edge, respectively, achieving surface contact clamping of the opening edge and completing the fastening installation of the fastening component. During subsequent use, pulling the quick-release fastening component will not cause sliding friction between the inner wall surface of the opening and the clamping contact surface of the slider, preventing wear on the inner wall surface of the opening and the slider, and preventing scratches on the stepped surface at the opening corners. Even after long-term use, the opening edge and the quick-release fastening component of this application maintain good assembly accuracy without significant loosening, significantly increasing the service life of the slider and the opening edge, improving the clamping stability and clamping effect of the quick-release fastening component of this application, resulting in excellent clamping effect, good clamping stability, and resistance to loosening. The slider in this application does not require a continuous squeezing force to press against the inner wall of the opening, nor does it require a strong elastic component. Only a compression spring with a small elastic force is needed to provide a restoring force for the slider's return movement. The mounting plane 20 of the step surface 8 and the base 1 uses a planar contact method with the back and front surfaces of the opening edge. This results in a large clamping contact area, improving the clamping stability and effect of the quick-release fastening assembly. The clamping effect is excellent, the clamping stability is good, and it is not easily loosened, unlike the linear contact method in patent application CN1914395B. Figure 1The small contact area leads to unstable clamping effect, which reduces the clamping effect and makes it easy to loosen. In addition, after the quick-installation fastening component of this application is assembled, the corners of the opening will not squeeze the clamping contact surface of the step surface 8, and will not damage the step surface 8. There will be no frictional wear between the opening edge, the step surface 8 and the assembly plane 20, which can maintain good assembly accuracy for a long time and is not easy to loosen, further improving clamping stability and clamping effect.

[0053] The quick-release fastening assembly also includes two sets of limiting components, which are used to prevent the two sliders 6 from sliding off the groove 5.

[0054] The limiting component includes:

[0055] A limiting groove 10 is formed in the assembly 4;

[0056] The limiting member 11 is fixed at one end to the slider 6 and inserted into the limiting groove 10 at the other end, and can move with the slider 6 within the limiting groove 10. Specifically, when the two sliders 6 are pressed and slide towards each other, the limiting member 11 moves from the outer end of the limiting groove 10 toward the other end of the limiting groove 10. When the pressure on the two sliders 6 is released, the sliders 6 drive the limiting member 11 back to the outer end of the limiting groove 10 under the force of the compression spring 7.

[0057] The limiting member 11 is a nut screw, one end of which is screwed to the slider 6, and the other end is inserted into the limiting groove 10.

[0058] The slide 5 is a V-shaped groove, and the minimum angle between the V-shaped groove and the horizontal plane is 5°-40°.

[0059] Specifically, the minimum angle between the V-groove and the horizontal plane is 10°. The V-groove is inclined at a 10° angle, which ensures smooth sliding of the slider 6.

[0060] The slide groove 5 adopts a V-groove design, which allows the quick-install fastening assembly of this application to move a certain distance along the vertical direction of the assembly plane 20 during the assembly process, as the two sliders 6 are pressed and slide towards each other. When the opening edge enters the receiving groove 9, the two sliders 6 slide outwards while moving a certain distance along the vertical direction of the assembly plane 20, thereby clamping the opening edge. The V-groove design of the slide groove 5 makes the receiving groove 9 suitable for accommodating the opening edges of plates of different thicknesses. When used for thinner plates, the sliding distance of the two sliders 6 is larger when they slide away from each other, resulting in a smaller thickness of the receiving groove 9. When used for thicker plates, the sliding distance of the two sliders 6 is smaller when they slide away from each other, resulting in a larger thickness of the receiving groove 9. Therefore, the quick-install fastening assembly of this application not only has good clamping stability and excellent clamping effect, but can also be assembled on the opening edges of plates of different thicknesses, making it widely applicable. In contrast, the prior art patent application CN1914395B can only be used for assembling the opening edges of plates of a specified thickness.

[0061] The slider 6 has an upper end face and a lower end face, both of which are inclined surfaces 12.

[0062] Specifically, two sliders 6 are symmetrically arranged in the slide groove 5. The inclination angles of the upper and lower surfaces of the slider 6 on the left side are consistent with the inclination angle of the left side of the slide groove 5, and the inclination angles of the upper and lower surfaces of the slider 6 on the right side are consistent with the inclination angle of the right side of the slide groove 5.

[0063] The slider 6 has an outer end face, which is an arc-shaped surface 13. This arc-shaped surface 13 design reduces the contact area between the inner wall of the opening and the outer end face 13 when the inner wall of the opening presses against it, thus reducing friction and significantly decreasing installation resistance. This facilitates the rapid installation of the quick-release fastening assembly.

[0064] The slider 6 is provided with two sliding extension blocks 14. The upper end face of one sliding extension block 14 is flush with the upper end face of the slider 6, and both the slider and the upper end face of the sliding extension block are slidably in contact with the upper wall of the groove. The lower end face of the other sliding extension block 14 is flush with the lower end face of the slider 6, and both the sliding extension block and the lower end face of the slider are slidably in contact with the lower wall of the groove. The surface contact between the sliding extension blocks 14, the slider 6, and the groove 5 effectively increases the sliding contact area, improves the sliding stability of the two sliders 6, and enhances the clamping stability and clamping effect of this application. Specifically, the two sliding extension blocks 14 are staggered. When the sliders 6 slide towards each other to the middle of the groove 5, the two sliding extension blocks 14 protruding from one slider 6 and the two sliding extension blocks 14 disposed on the other slider 6 respectively engage with each other.

[0065] The slider 6 is provided with a spring position 15, which is located on the opposite side of the two sliders 6 and is used to connect one end of the compression spring 7.

[0066] Specifically, the spring position 15 is a cross-shaped connecting post, and the end of the compression spring 7 is sleeved outside the cross-shaped connecting post.

[0067] See Figure 8 .

[0068] A quick-release hinge includes two quick-release fastening components as described above. The base of one quick-release fastening component serves as the fixed hinge leaf 18, and the base of the other quick-release fastening component serves as the movable hinge leaf 17. The fixed hinge leaf 18 and the movable hinge leaf 17 are hinged together. Specifically, the fixed hinge leaf 18 can be quickly and securely installed in the opening of the fixed component via the quick-release fastening components, and the movable hinge leaf 17 can be quickly assembled with the opening of the movable component via the quick-release fastening components. The quick-release hinge is not prone to loosening even after prolonged use.

[0069] See Figure 7 .

[0070] A quick-release handle includes a quick-release fastening assembly as described above, wherein the base of the quick-release fastening assembly serves as the handle body 19. Specifically, the quick-release handle can be quickly assembled into an opening in a panel using the quick-release fastening assembly, and it is not easily loosened after prolonged pulling or dragging.

[0071] See Figures 2-10 .

[0072] A quick-install door lock includes a quick-install fastening assembly as described above. The base serves as the main body of the door lock and further includes a hook disposed on the mounting surface 20 of the main body of the door lock. A groove is formed between the hook and the mounting surface 20 for the opening edge of the door panel to engage.

[0073] Specifically, the hook 2 is located on the upper part of the mounting plane 20 of the base 1, and the assembly 4 is located on the lower part of the base 1. In the actual assembly process of the quick-install door lock, the hook 2 is first inserted into the pre-reserved opening in the door panel. At this time, the edge of the door panel opening is engaged in the slot 3. Then, the assembly 4 is pushed into the opening. During the pushing process, the two sliders 6 are squeezed by the inner wall of the opening and slide towards each other along the slide groove 5 and compress the compression spring 7. Thus, the sliders 6 make way for the space for the edge of the opening to enter the receiving groove 9. After the assembly 4 is pushed into place, the edge of the door panel enters the receiving groove 9, and the inner wall of the opening no longer squeezes the sliders 6. The compression spring 7 releases its elasticity and pushes the two sliders 6 to slide in opposite directions along the slide groove 5 until the step surface 8 presses against the back of the edge of the opening. At this time, the mounting plane 20 presses against the front end of the edge of the opening, completing the surface contact installation of the door lock.

[0074] After the slider 6 is reset, the front end face of the door panel abuts against the mounting plane 20 of the base 1, and the rear end face of the door panel abuts against the step surface 8, thus cooperating with the hook 2 to complete the quick-installation of the quick-release door lock of this application. After installation, the quick-release door lock is fixed by the contact between the stepped surface 8 and the mounting surface of the base 1 with the rear and front surfaces of the door panel, respectively. During subsequent use, when unlocking and pulling the door lock handle, there will be no sliding friction between the inner wall of the opening and the slider 6. The mounting surface of the stepped surface 8 and the mounting surface of the base 1 are in planar contact with the front and back surfaces of the door panel, rather than the linear contact method as in patent application CN1914395B. The corners of the opening will not squeeze or damage the stepped surface 8, so that the inner wall of the opening and the slider 6 will not be worn. After long-term use, the door panel and the quick-release door lock of this application can maintain good assembly accuracy and will not loosen significantly, which significantly increases the service life of the slider 6 and the door panel. Moreover, the door panel of this application can be used for door panels of different thicknesses, making it widely applicable.

[0075] The slider 6 of this application does not need to continuously maintain a certain squeezing force to press against the inner wall of the opening, and does not need to be provided with a strong elastic component. It only needs to be provided with a compression spring 7 with a small elastic force to provide a restoring force for the slider 6 to reset.

[0076] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present invention are within the protection scope of the present invention.
