TECHNICAL FIELD
[0001] The utility model relates to the field of reset handle, especially to a detachable self-reset handle of door. BACKGROUND
[0002] Reset handle is a common mechanical structure, which is often used in door plate structure and has the characteristics of good stability, safety and the like. The main principle is to realize the reset function of different angles through internal torsional spring and corresponding mechanical structure.
[0003] Since the reset handle has a high frequency of use, the internal structure is easy to wear, and the torsional spring strength is reduced, so it needs to be disassembled and repaired. At present, most products on the market need special tools to disassemble the fixed parts of the handle, and then replace the internal structure, which is difficult to operate, resulting in the handle assembly being replaced as a whole in most cases, thereby increasing the use cost.
[0004] Therefore, it is necessary to develop a new type of reset handle product to reduce the disassembly difficulty and facilitate the later use. UTILITY MODEL CONTENT
[0005] The utility model discloses a detachable self-reset handle of door, which is easy to disassemble and has good interchangeability, and reduces the maintenance cost in later use.
[0006] Technical scheme: the detachable self-reset handle of door of the utility model, characterized in that: the handle is provided with a threaded hole on one side, a square hole for connection and transmission is formed in the inner side of the handle, the handle and the connecting shaft are connected through the fixed pin penetrating the corresponding threaded hole, and the handle and the connecting shaft are transmitted through the square hole; the handle shell is connected through the first countersunk head screw, a countersunk hole is formed in the top of the connecting shaft, and the connecting shaft and the lock rod are connected through the second countersunk head screw penetrating the countersunk hole.
[0007] The threaded hole of the handle and the connecting shaft is a single-sided hole.
[0008] The handle and the handle shell are provided with a gasket.
[0009] The connecting shaft and the handle shell are provided with a torsional spring.
[0010] The boss on the connecting shaft drives one end of the torsional spring to rotate, thereby increasing the torsional force. When the handle is loosened, automatic reset is realized.
[0011] The handle, the fixed pin, the connecting shaft, the handle shell and the lock rod are all stainless steel parts.
[0012] The torsional spring is a stainless steel wire spring.
[0013] Beneficial effects: compared with the prior art, the utility model has the following remarkable advantages: the utility model internal parts are easy to disassemble, good interchangeability, reduce the later use maintenance cost. Through the torsional spring, automatic reset can be realized, and operation is facilitated. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0021] The technical scheme of the utility model will be further described below in combination with the drawings and specific embodiments.
[0022] The detachable self-reset handle of the utility model comprises a handle 1, a threaded hole 2 is formed on one side of the handle 1, a square hole 3 for connection and transmission is formed on the inner side of the handle 1, the handle 1 and the connecting shaft 5 are connected through the fixed pin 4 penetrating the corresponding threaded hole 2, and the handle 1 and the connecting shaft 5 are transmitted through the square hole 3;The hand shell 6 between the handle 1 is connected through the first countersunk screw 7, the top of the connecting shaft 5 is provided with a countersunk hole 12, and the connecting shaft 5 and the lock rod 8 are connected through the second countersunk screw 9 penetrating the countersunk hole 12.
[0023] The threaded hole 2 of the handle 1 and the connecting shaft 5 is a single-sided hole. The handle 1 and the hand shell 6 are provided with a washer 10. The connecting shaft 5 and the hand shell 6 are provided with a torsional spring 11. The boss 13 on the connecting shaft 5 drives one end of the torsional spring 11 to rotate, thereby increasing the torsion. When the handle is released, automatic reset is realized. The handle 1, the fixed pin 4, the connecting shaft 5, the hand shell 6 and the lock rod 8 are all stainless steel parts. The torsional spring 11 is a stainless steel wire spring.
[0024] Further, the first countersunk head screw 7 is M4, the second countersunk head screw 9 is M3, and the materials are stainless steel. The length of the lock rod 9 is 120mm, and it is suitable for a door plate of 60-65mm; but different lengths of lock rods and countersunk head screws can be replaced to meet the needs of different thickness door plates. The threaded hole 2 of the handle 1 is an M6 single-sided opening, and the square hole 3 is a blind hole. The threaded hole 2 of the connecting shaft 5 is an M6 single-sided opening, and the countersunk hole 12 is an M3 tapered hole.
[0025] The utility model discloses adopt detachable assembly type structure, internal part is easy to dismantle, and interchangeability is good, and reduces the later use maintenance cost. Through torsional spring, automatic reset can be realized, and it is convenient to operate.
