Description

Technical Field

[0001] This application relates to the field of handle technology, specifically a handle. Background Technology

[0002] Handles are the part of an object that is held in the hand, usually for the convenience of users to grip or operate it. The design of handles is crucial in product design, as it not only affects the product's style and user experience, but also determines the product's interaction method and the degree of user preference.

[0003] The existing handles are usually fixed to the door panel with screws during installation. This is not only difficult to disassemble and replace, but the screws can also damage the door panel structure, affecting the appearance of the door panel and its reuse after disassembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a handle that facilitates installation and removal, makes disassembly and maintenance convenient, avoids the use of screws for handle positioning, prevents damage to the door panel, and addresses the issues of existing handles requiring screws to fix the handle to the door panel during installation. This not only makes disassembly and replacement laborious but also causes damage to the door panel structure, affecting its appearance and subsequent reuse.

[0005] To achieve the above objectives, this application provides the following technical solution: a handle, comprising a lock body, wherein a square rod is slidably inserted into the interior of the lock body, and mounting rods are fixedly connected to both sides of the square rod. A collar is slidably sleeved on the outer circumferential surface of each mounting rod, and a mounting plate is slidably sleeved on the outer circumferential surface of each mounting rod. A handle is fixedly connected to the top of each mounting plate. A lead screw is rotatably connected inside each mounting plate, and a positioning rod is threadedly connected to the outer circumferential surface of the lead screw. A positioning hole is provided inside each mounting rod, and the outer circumferential surface of the positioning rod is slidably inserted into the mounting rod through the positioning hole. Two torsion spring seats are fixedly connected to the outer surface of the lock body, and a torsion spring is sleeved on the outside of each torsion spring seat. Two fixing blocks are fixedly connected to the outer surface of the lock body, and the two ends of the torsion springs are respectively in contact with the outer surface of the fixing blocks. A insertion ring is fixedly connected to one end of each torsion spring, and an insertion rod is fixedly connected to the outer surface of each collar. The insertion rod is slidably inserted into the insertion ring.

[0006] The above solution addresses the issue that existing handles typically require screws to fix them to the door panel during installation. This not only makes disassembly and replacement laborious but also damages the door panel structure, affecting its appearance and future usability. By rotating a lead screw to move a positioning rod into the positioning hole, the mounting plate is directly fixed to the mounting rods at both ends of the square rod. This facilitates handle installation, disassembly, and maintenance, saves manpower, and avoids the need for screws to fix the handle to the door panel, preventing damage to the door panel, affecting its appearance, and hindering future usability.

[0007] Furthermore, each of the mounting rods has two sliding grooves slidably fitted onto its outer circumferential surface, and each of the collars has two sliding plates fixedly connected to its inner wall. The outer surfaces of the sliding plates are slidably connected to the mounting rods through the sliding grooves, and the side of the collar closest to the torsion spring seat contacts the outer surface of the torsion spring seat.

[0008] Through the above scheme, the slide and slide plate can restrict the collar, causing the collar to always rotate with the mounting rod. In turn, the insertion rod drives the insertion ring and the torsion spring to rotate. The collar in contact with the torsion spring seat can restrict the square rod, limit the lateral movement of the square rod, and increase the overall stability of the handle.

[0009] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the lead screw, and the outer circumferential surface of the limiting ring is rotatably connected to the interior of the mounting plate.

[0010] The above method restricts the lead screw, preventing it from slipping and deviating, and improving the stability of the lead screw's movement.

[0011] Furthermore, a limiting block is fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of the limiting block is slidably connected to the mounting plate through a slot opened inside the mounting plate.

[0012] The above method restricts the positioning rod, causing it to always move vertically up and down, thus preventing it from rotating along with the lead screw.

[0013] Furthermore, each of the mounting rods has a decorative cover threaded onto its outer circumferential surface, and a sealing sheet is fixedly connected to the side of the decorative cover closest to the mounting plate.

[0014] The above solution not only protects the mounting rod but also enhances the overall aesthetics of the handle, while the sealing plate seals the gap between the decorative cover and the mounting plate, optimizing the protective effect of the decorative cover.

[0015] Furthermore, each of the mounting rods has a positioning ring threaded onto its outer circumferential surface, and a gasket is fixedly connected to the side of the positioning ring closest to the mounting plate, with the side of the gasket closest to the mounting plate in contact with the mounting plate.

[0016] The above solution reinforces the mounting plate and improves the stability of the connection between the mounting plate and the mounting rod. The gasket protects the mounting plate and prevents damage to the mounting plate when the positioning ring is rotated during installation or removal.

[0017] Furthermore, a knob is fixedly sleeved at the bottom of the lead screw, and the outer circumferential surface of the knob is provided with anti-slip protrusions arranged at equal intervals.

[0018] The above solution facilitates the rotation of the lead screw by setting the knob, and the anti-slip protrusions on the knob can effectively prevent the hand from slipping.

[0019] Furthermore, each of the mounting rods has two limit keys fixedly connected to its outer circumferential surface, and each of the mounting plates has two keyways inside, with the limit keys slidably connected to the mounting plate through the keyways.

[0020] The above solution ensures that the mounting plate can always drive the mounting rod and square rod to rotate, improving the stability during the handle rotation operation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This handle uses a rotating screw to move a positioning rod into a positioning hole, directly fixing the mounting plate to the mounting rods at both ends of the square rod. This facilitates the installation, disassembly, and maintenance of the handle, saving manpower and avoiding the use of screws to fix the handle to the door panel, which could damage the door panel, affect its appearance, and hinder its reuse after disassembly. It solves the problem that using screws to fix the handle to the door panel is not only laborious during disassembly and maintenance, but also that screws can damage the door panel structure, affecting its appearance and subsequent reuse.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, a handle includes a lock body 1. A square rod 2 is slidably inserted into the lock body 1. Mounting rods 3 are fixedly connected to both sides of the square rod 2. A collar 4 is slidably sleeved on the outer circumferential surface of each mounting rod 3. A mounting plate 6 is slidably sleeved on the outer circumferential surface of each mounting rod 3. A handle 7 is fixedly connected to the top of each mounting plate 6. A lead screw 8 is rotatably connected inside each mounting plate 6. A positioning rod 9 is threadedly connected to the outer circumferential surface of the lead screw 8. A positioning hole 10 is opened inside each mounting rod 3. The outer circumferential surface of the positioning rod 9 is slidably inserted into the mounting rod 3 through the positioning hole 10.

[0032] Please see Figure 2 , Figure 3 and Figure 4 Two torsion spring seats 12 are fixedly connected to the outer surface of the lock body 1. Each torsion spring seat 12 is fitted with a torsion spring 13. Two fixing blocks 14 are fixedly connected to the outer surface of the lock body 1. The two ends of the torsion spring 13 are in contact with the outer surface of the fixing block 14. One end of each torsion spring 13 is fixedly connected with a plug ring 15. The outer surface of each collar 4 is fixedly connected with a plug rod 16. The plug rod 16 is slidably inserted into the plug ring 15.

[0033] Please see Figure 3 , Figure 4 and Figure 5Each mounting rod 3 has two sliding grooves 5 slidably fitted on its outer circumferential surface, and each collar 4 has two fixedly connected sliding plates 22 on its inner wall. The outer surfaces of the sliding plates 22 are slidably connected to the mounting rod 3 through the sliding grooves 5. The side of the collar 4 closest to the torsion spring seat 12 contacts the outer surface of the torsion spring seat 12. The sliding grooves 5 and the sliding plates 22 can restrict the collar 4, causing the collar 4 to always rotate with the mounting rod 3. In turn, the insertion rod 16 drives the insertion ring 15 and the torsion spring 13 to rotate. The collar 4 in contact with the torsion spring seat 12 can restrict the square rod 2, restricting the lateral movement of the square rod 2 and increasing the overall stability of the handle.

[0034] Please see Figure 4 A limiting ring 17 is fixedly sleeved on the outer circumferential surface of the lead screw 8. The outer circumferential surface of the limiting ring 17 is rotatably connected to the inside of the mounting plate 6 to restrict the lead screw 8, prevent the lead screw 8 from sliding and deviating, and improve the stability of the movement of the lead screw 8.

[0035] Please see Figure 4 The outer circumferential surface of the positioning rod 9 is fixedly connected to the limiting block 18. The outer surface of the limiting block 18 is slidably connected to the mounting plate 6 through the slot opened inside the mounting plate 6, which restricts the positioning rod 9 and causes the positioning rod 9 to always move vertically up and down, preventing the positioning rod 9 from rotating with the lead screw 8.

[0036] Please see Figure 2 , Figure 3 and Figure 4 Each mounting rod 3 has a decorative cover 19 threadedly connected to its outer circumference. A sealing plate is fixedly connected to the side of the decorative cover 19 closest to the mounting plate 6. The decorative cover 19 not only protects the mounting rod 3 but also improves the overall aesthetics of the handle. The sealing plate seals the gap between the decorative cover 19 and the mounting plate 6, thus optimizing the protective effect of the decorative cover 19.

[0037] Please see Figure 3 and Figure 4 Each mounting rod 3 has a positioning ring 11 threadedly connected to its outer circumference. A gasket 20 is fixedly connected to the side of the positioning ring 11 near the mounting plate 6. The side of the gasket 20 near the mounting plate 6 contacts the mounting plate 6. The positioning ring 11 can reinforce the mounting plate 6 and improve the stability of the connection between the mounting plate 6 and the mounting rod 3. The gasket 20 protects the mounting plate 6 and prevents damage to the mounting plate 6 when the positioning ring 11 is rotated for installation or removal.

[0038] Please see Figure 2 , Figure 3 and Figure 4 A knob 21 is fixedly sleeved at the bottom of the lead screw 8. The outer circumferential surface of the knob 21 is provided with anti-slip protrusions arranged at equal intervals. The knob 21 is designed to facilitate the rotation operation of the lead screw 8, and the anti-slip protrusions on the knob 21 can effectively prevent the hand from slipping.

[0039] Please see Figure 3 , Figure 4 and Figure 5 Two limit keys 23 are fixedly connected to the outer circumference of each mounting rod 3, and two keyways 24 are opened inside each mounting plate 6. The limit keys 23 are slidably connected to the mounting plate 6 through the keyways 24, so that the mounting plate 6 can always drive the mounting rod 3 and the square rod 2 to rotate, thereby improving the stability of the handle rotation operation.

[0040] In this embodiment, a handle is installed by rotating a lead screw 8 to move a positioning rod 9 into a positioning hole 10, directly fixing the mounting plate 6 to the mounting rods 3 at both ends of the square rod 2. This facilitates the installation, disassembly, and maintenance of the handle, saves manpower, and avoids the use of screws to fix the handle to the door panel, preventing damage to the door panel, affecting its appearance, and hindering its reuse after disassembly. This solves the problem that using screws to fix the handle and door panel is not only laborious during disassembly and maintenance, but also damages the door panel structure, affecting its appearance and subsequent reuse after disassembly.

[0041] It should be noted that both the positioning ring 11 and the decorative cover 19 have equidistantly arranged anti-slip protrusions on their outer circumferential surfaces, which facilitates the rotation of the positioning ring 11 and the decorative cover 19.

[0042] The working principle of the above embodiments is as follows:

[0043] When installing the handle, install the lock body 1 inside the door panel, insert the square rod 2 into the lock body 1, and then put the collar 4 onto the mounting rod 3, so that the insert rod 16 on the collar 4 is inserted into the insert ring 15 at one end of the torsion spring 13. Next, install the mounting plate 6 that drives the handle 7 onto the mounting rod 3. Rotate the screw 8 to move the positioning rod 9 upward, causing the positioning rod 9 to insert into the positioning hole 10, thus completing the positioning of the mounting plate 6. Tighten the positioning ring 11 onto the mounting rod 3, ensuring that the outer surface of the positioning ring 11 is in close contact with the outer surface of the mounting plate 6. Finally, install the decorative cover 19 at both ends of the mounting rod 3. When the handle is in use, press down on handle 7. Handle 7 drives the mounting rod 3 and square rod 2 to rotate via mounting plate 6. Square rod 2 drives lock body 1 to open and close. When mounting rod 3 rotates, it drives the insertion rod 16 to rotate via collar 4. Insertion rod 16 drives torsion spring 13 to rotate via insertion ring 15. After releasing the handle, insertion rod 16 will rotate under the action of torsion spring 13, which in turn causes collar 4, mounting rod 3, square rod 2, mounting plate 6 and handle 7 to rotate. When disassembling the handle, the rotating screw 8 drives the positioning rod 9 to move out of the positioning hole 10. Then, the decorative cover 19, positioning ring 11 and mounting plate 6 can be removed in sequence.
