Description

Technical Field

[0001] This invention belongs to the field of hardware accessories technology, specifically relating to a quick installation device that can flexibly adapt to various hardware accessories. Background Technology

[0002] In the practical installation of door and window hardware, typical products such as door and window handles and door pulls have long relied on the traditional set screw locking method, leading to significant installation inconveniences. Specifically, during the installation of these handles, it is usually necessary to insert the square steel inside the handle into the square hole of the lock body, and then tighten the set screw through the small hole on the side of the handle, so that the end of the screw abuts against the square steel to achieve fixation. Due to the extremely narrow operating space inside the handle, installers often find it difficult to apply effective force using a standard screwdriver or Allen wrench, resulting in insufficient tightening torque or excessive stripping of the screw threads. This is even more difficult to do at heights or in low-light environments. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a quick installation device that can be flexibly adapted to various hardware accessories, thereby improving the convenience of the device during installation and disassembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention discloses a quick-installation device that can flexibly adapt to various hardware accessories, including a quick-installation base and a quick-installation guide connected to the quick-installation base. The center of the quick-installation guide forms a central channel for the passage of a locking pin. The inner wall of the central channel has a groove along the axial direction, which engages with the edge of the locking pin. The quick-installation base includes a cylindrical seat, with an inclined support connected to the upper end of the seat. The upper surface of the inclined support forms an inclined surface, and a positioning post is connected to the lower end of the seat. A positioning groove is formed on the positioning post at the end away from the seat. The quick-installation guide includes a guide plate and two pillars fixedly connected to the guide plate. The guide plate is installed on the upper side of the base at intervals and is connected to the base by two pillars. Two sets of locking plates are stacked on the inclined surface. The locking plates have a certain thickness and a square hole in the center of the locking plate that mates with the locking pin. The outer side of the locking plates has a groove that mates with the pillar. A first support spring is set between the uppermost set of locking plates and the guide plate. The first support spring is used to press the locking plates against the inclined surface. Under the action of the inclined surface of the quick-release base, the locking plates and the locking pin are kept at a certain angle. Locking is achieved by the friction of the inclination.

[0006] Furthermore, the support column is a long strip structure, and the outer side of the support column forms an outer arc surface, the curvature of which corresponds to the curvature of the outer side of the base body. The outer side of the support column and the outer side of the base body form a cylindrical surface of equal diameter.

[0007] Furthermore, the inner side of the support column forms an inner arc surface, the curvature of which corresponds to the curvature of the outer side of the inclined support seat. The groove is a U-shaped groove, which is slidably set on the outer side of the support column. The bottom of the groove forms an arc-shaped protrusion structure that adapts to the inner arc surface of the support column.

[0008] Furthermore, the inner side of the support column is threaded with a pressure ring, the outer side of the pressure ring is threaded with an external thread, and the inner side of the support column is threaded with an internal thread that mates with it. The lower surface of the pressure ring abuts against the upper end of the first support spring. By rotating the pressure ring, the compression degree of the first support spring can be changed.

[0009] Furthermore, a pin hole is provided on the outer side of the positioning post, the pin hole extends inward along the radial direction of the positioning post, a positioning pin is slidably installed on the inner side of the pin hole, and a second support spring is installed at the bottom of the pin hole, the second support spring is connected to the inner end of the positioning pin.

[0010] Furthermore, the inclined support includes a base and a wedge-shaped seat. The base is fixedly connected to the seat body, and the lower end of the wedge-shaped seat is hinged to the base. An adjustable support device is installed on the base, which is used to support the upper end of the wedge-shaped seat.

[0011] Furthermore, the adjustable support device includes a support column, a threaded hole on the base, the threaded hole passing through the base and the seat body in the circumferential direction, the upper end of the support column abutting against the bottom of the high end of the wedge-shaped seat, the upper end of the support column forming a ball head, and the lower end of the support column having a cross groove.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention discloses a quick installation device that can flexibly adapt to various hardware accessories. When installing a locking pin, it is directly inserted into the hole of the base. Under the pressure of two sets of locking plates, the locking pin can be quickly locked. When disassembling, the lower end of the locking plate is lifted to release the pressure of the locking plate on the locking pin, making it easy to disassemble. This greatly improves the convenience of the device in the installation and disassembly process. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-8 As shown, this invention discloses a quick-installation device that can flexibly adapt to various hardware accessories, including a quick-installation base 1 and a quick-installation guide 2 connected to the quick-installation base 1. In this embodiment, the quick-installation base 1 and the quick-installation guide 2 are connected together by welding. The center of the quick-installation guide 2 forms a central channel for the passage of the locking pin 3. The inner wall of the central channel has a groove 4 along the axial direction, which extends circumferentially. The groove 4 engages with the edge of the locking pin 3, allowing the locking pin 3 to rotate.

[0025] The quick-install base 1 includes a cylindrical base 5, which can be cylindrical or square. The upper end of the base 5 is connected to an inclined support 6, the upper surface of which forms an inclined surface. The lower end of the base 5 is connected to a positioning post 7, and a positioning groove 8 is provided on the end of the positioning post 7 away from the base 5, which can facilitate positioning and installation at the corresponding position of the door or window.

[0026] The quick-installation guide component 2 includes a guide plate 9 and two support columns 10 fixedly connected to the guide plate 9. The guide plate 9 is a circular sheet structure. The guide plate 9 is installed at intervals on the upper side of the base 5. The guide plate 9 is connected to the base 5 through the two support columns 10, which form two legs of the guide plate 9. Two sets of locking clips 11 are stacked on the inclined surface. The locking clips 11 have a certain thickness, and the center of the locking clips 11 has a square hole 12 that mates with the locking pin 3. A groove 13 is provided on the outer side, which cooperates with the support column 10. A first support spring 14 is provided between the uppermost set of locking clips 11 and the guide plate 9. The first support spring 14 is used to press the locking clips 11 against the inclined surface. Under the action of the inclined surface of the quick-release base 1, the locking clips 11 and the locking pin 3 are kept at a certain angle. Locking is achieved by the friction of the inclined surface. The hardness of the locking pin 3 after high-frequency quenching should reach HRC46~HRC48.

[0027] The specific locking principle of this invention is as follows: When the quick-release device is not inserted with the locking pin 3, the two locking plates 11, guided by the quick-release guide 2 and pushed by the first support spring 14, adhere to the inclined surface of the inclined support base 6. When the locking pin 3 is inserted into the quick-release device, the two locking plates 11 are pushed upwards and maintain a certain locking posture, and the first support spring 14 is compressed again. Under the action of the spring rebound force and the guidance of the quick-release guide 2, the grooves 13 on both sides of the locking plates 11 slide linearly and displace with the support column 10 of the quick-release guide 2. Under the action of the inclined surface of the quick-release base 1, the locking plates 11 are kept in a certain angle of inclination, which locks the locking pin 3.

[0028] The locking pin's force-output principle: The locking plate 11 is designed with a reasonable gap and, when in contact with the inclined surface, forms an angle with the locking pin. Under the spring's pushing force F, the two locking plates 11 generate a force F1 at the A contact surface between the locking plate 11I and the locking pin 3. The locking plate 11II generates a force F2 at the B contact surface between the locking plate 11I and the locking pin 3. Under the action of F1 and F2, the two locking plates 11 lock the locking pin, thus fixing it in place. Using two sets of locking plates 11 in cooperation allows for quick locking of the locking pin 3. During disassembly, lifting the lower end of the locking plate 11 releases the pressure on the locking pin 3, facilitating disassembly and greatly improving the convenience of handle installation and disassembly.

[0029] In this embodiment, the support column 10 is a long strip structure, and the outer side of the support column 10 forms an outer arc surface 15, the curvature of which corresponds to the curvature of the outer side of the base 5. The outer side of the support column 10 and the outer side of the base 5 are formed on a cylindrical surface of equal diameter, which facilitates the subsequent installation of the handle, reduces the gap between the handle and the base 5, and makes the use more stable.

[0030] In this embodiment, the inner side of the support column 10 forms an inner arc surface 16, the curvature of which corresponds to the curvature of the outer side of the inclined support seat 6. The groove 13 is a U-shaped groove, and the groove 13 is slidably disposed on the outer side of the support column 10. The bottom of the groove 13 forms an arc-shaped protrusion structure 17 that adapts to the inner arc surface 16 of the support column 10, which can reduce the smoothness of the locking and clamping piece 11 sliding along the support column 10 and reduce the possibility of the device getting stuck during use.

[0031] In this embodiment, a pressure ring 18 is threadedly connected to the inner side of the support column 10. The outer side of the pressure ring 18 is provided with an external thread, and the inner side of the support column 10 is provided with an internal thread that mates with it. The lower surface of the pressure ring 18 abuts against the upper end of the first support spring 14. By rotating the pressure ring 18, the compression degree of the first support spring 14 can be changed, thereby changing the pre-support force of the first support spring 14 to adapt to actual needs.

[0032] In this embodiment, a pin hole 19 is provided on the outer side of the positioning post 7. The pin hole 19 extends radially inward along the positioning post 7. A positioning pin 20 is slidably installed on the inner side of the pin hole 19. A second support spring 21 is installed at the bottom of the pin hole 19 and is connected to the inner end of the positioning pin 20. The positioning pin 20 is used to connect with the handle. With the above structure, the handle can be installed conveniently and the installation efficiency is faster.

[0033] In some other embodiments, the inclined support 6 is formed separately from the base body 5. The inclined support 6 includes a base 22 and a wedge-shaped seat 23. The base 22 is fixedly connected to the base body 5. The lower end of the wedge-shaped seat 23 is hinged to the base 22. An adjustable support device is installed on the base 22. The adjustable support device is used to support the upper end of the wedge-shaped seat 23. By adjusting the adjustable support device, the height of the upper end of the wedge-shaped seat 23 can be changed, thereby adjusting the inclination of the inclined surface.

[0034] In this embodiment, the adjustable support device includes a support column 24, a threaded hole 25 on the base 22, the threaded hole 25 passing through the base 22 and the seat body 5 in the circumferential direction, the upper end of the support column 24 abutting against the bottom of the high end of the wedge-shaped seat 23, the upper end of the support column 24 forming a ball head, and the lower end of the support column 24 having a cross groove 26, which can be used with a screwdriver to facilitate the adjustment of the support height of the support column 24.
