DETAILED DESCRIPTION

[0025] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0026] Handles are often installed on doors, windows, or mechanical equipment. Conventional technology often requires fastening the two ends of a handle (e.g., a door lock handle) together with a set screw 315 (fixing member 310). This is inconvenient and time-consuming to install. Furthermore, if the handle is pulled for extended periods, the screws 315 connecting the two ends of the handle can easily rotate with the movement of the door handle, causing the screws 315 to loosen over time.

[0027] The technical solution of the embodiment of the present application solves the problems of unstable handle structure, inconvenient installation and high installation cost in the prior art by providing a quick-release handle. The reversely installed fixing part 310 combined with the screw-locking part 320 achieves the beneficial effects of structural stability, easy installation and reduced installation cost.

[0028] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0029] A quick-release handle is provided, comprising a handle 1 and a main body 300. The main body 300 comprises a first subsection 100 and a second subsection 200, each of which is provided with a first base 110 and a second base 210, respectively. The first base 110 is provided with a fixing member receiving portion 111. The first subsection 100 and the second subsection 200 are centrally connected by a connector 330. Furthermore, the handle comprises a fixing member 310 (screw 315) and a locking member 320 (locking plate 321) matching the fixing member 310. The fixing member 310 comprises a rod 311 and a head 313. The rod 311 is pre-installed in the fixing member 310 receiving portion 111, and the head 313 passes through the second base 210 and the locking member 320. Furthermore, a series of technical measures are employed. By rotating the locking member 320 in a preset direction and at a preset angle, a pulling force can be applied to the head 313 of the reversely installed fixing member 310 to tighten the fixing member 310, thereby completing the installation of the handle in a short time and reducing the labor time required for installation; when the handle 1 rotates, the fixing member 310 is not driven, reducing the chance of the fixing member 310 loosening.

[0030] During installation, there's no need to tighten fixing member 310 (screw 315) with a screwdriver. Instead, tighten locking member 320 (locking plate 321) to a desired angle to secure screw 315. Installation takes only seconds. This eliminates the need to tighten screw 315, improving installation convenience. When opening the door, turning handle 1 (door handle) does not move locking member 320. This eliminates external force on screw 315, preventing loosening and improving structural stability.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] A quick-release handle, as shown in Figures 1 and 2, consists of a handle 1 and a main body 300. The main body 300 consists of a first subsection 100 and a second subsection 200. The first subsection 100 and the second subsection 200 are respectively provided with a first base 110 and a second base 210. The first base 110 and the second base 210 are respectively connected to the handle 1 at one end away from the main body 300. The centers of the first subsection 100 and the second subsection 200 are connected by a connecting piece 330. The first base 110 is provided with a fixing piece 310. The accommodating portion 111 also includes a fixing member 310 and a locking member 320 matching the fixing member 310. The locking member 320 is located at the end of the second base 210 away from the main body 300. The fixing member 310 is composed of a rod 311 and a head 313. The rod 311 is movably pre-installed in the accommodating portion 111 of the fixing member 310, and the head 313 passes through the second base 210 and the locking member 320 in the direction a. The locking member 320 is twisted at a preset angle in a preset direction (direction b) to tighten the fixing member 310.

[0033] Specifically, the fixing member 310 is a screw 315 , and the external thread is located on the outer wall of the rod 311 ; the inner wall of the accommodating portion is provided with an internal thread corresponding to the external thread; and both ends of the connecting member 330 are detachably fixed in the handle 1 .

[0034] Specifically, the connecting member 330 is a square rod 331 .

[0035] More specifically, the locking member 320 is a locking piece 321;

[0036] Specifically, the accommodating portion is two screw hole sleeves 112; the fixing member 310 is two screws 315, preferably cross head countersunk screws M4X60.

[0037] During installation, there is no need to tighten the fixing member 310 (screw 315) with a screwdriver 315.

[0038] In order to increase the locking force of the fixing member 310 (screw 315); the locking member 320 has a Tai Chi diagram structure, and the surface of the locking member 320 is provided with an ascending curved surface 325. By rotating the locking member 320 in a preset direction and at a preset angle, the ascending curved surface 325 applies pressure to the head 313 of the fixing member 310 pre-installed at the factory to tighten the fixing member 310 (screw 315). The preset angle is within 180 degrees clockwise or within 180 degrees counterclockwise, and preferably the preset angle is within 90 degrees clockwise or within 90 degrees counterclockwise. During installation, the locking member 320 can complete the locking of the fixing member 310 (screw 315) within 10 seconds.

[0039] The structure of the clockwise locking piece 321 is symmetrical to the structure of the counterclockwise locking piece 321 .

[0040] As shown in Figures 3 and 4, the main body 300 also includes a cylindrical conical end set screw 2, a decorative meson 3, a first decorative cover 120, a coil spring 10, a positioning meson 20, a retaining spring 30, a gasket 40, a countersunk screw 315 and a second decorative cover 220; the first decorative cover 120 and the second decorative cover 220 are respectively mounted on the outside of the first base 110 and the second base 210; a locking member 320 is provided between the second base 210 and the second decorative cover 220; a coil spring 10, a positioning meson 20, a retaining spring 30 and a gasket 40 are provided on the side of the first base 110 and the second base 210 away from the handle 1; a cylindrical conical end set screw 2 is installed on the end of the handle 1 close to the connecting member 330.

[0041] The locking plate 321 consists of two arcuate grooves 323 with ascending curved surfaces 325, two recessed areas 327, and a central through-hole. The arcuate grooves 323 are located within the circumference of the locking plate 321. The heads of the two screws 315, pre-installed in the two screw hole sleeves 112 at the factory, pass through the widest end of the arcuate grooves 323. At this location, the ascending curved surfaces 325 are at their lowest point. As the locking plate 321 is tightened, the tightening force exerted by the ascending curved surfaces 325 on the heads 313 of the screws 315 increases as the ascending curved surfaces 325 approach the heads 313 of the screws 315. When the locking plate 321 is tightened to the end of the ascending curved surfaces 325, away from the widest end, the tightening force exerted by the ascending curved surfaces 325 on the heads 313 of the screws 315 is at its maximum, securing the screws 315 with maximum force.

[0042] In order to further prevent the locking plate 321 from shifting, the recess 327 is recessed from the circumference of the locking plate 321 toward the center of the circle to form a mortise and tenon structure; the second decorative cover 220 is provided with a protrusion 221 coupled with the recess to form a tenon structure; the recess 327 of the locking plate 321 and the protrusion 221 of the second decorative cover 220 form a mortise and tenon structure, which can effectively fix the locking plate 321 to prevent the locking plate 321 from shifting.
