DETAILED DESCRIPTION

[0036] The technical scheme provided by the utility model has the following general idea:

[0037] Please refer to Figures 1 to 9 The folding handle with lock comprises a handle shell 100, and the handle shell 100 is provided with a containing cavity 110; the handle shell 100 is the main body structure of the whole folding handle, and the containing cavity 110 is arranged in the handle shell 100 and used for containing a folding linkage assembly 200 and a handle piece 300;

[0038] folding linkage assembly 200 is arranged in the accommodating cavity 110 and is rotatably connected with the handle shell 100; the folding linkage assembly 200 is arranged in the accommodating cavity 110 and is rotatably connected with the handle shell 100, and allows the handle piece 300 to be extended or retracted into the accommodating cavity 110 when needed;

[0039] the handle piece 300 is rotatably connected with the folding linkage assembly 200, and the handle piece 300 is extended or retracted into the accommodating cavity 110 through the folding linkage assembly 200, and one end of the handle piece 300 is provided with a locking part 310; the handle piece 300 is rotatably connected with the folding linkage assembly 200, and through the linkage of the folding linkage assembly 200, the handle piece 300 can be extended or retracted into the accommodating cavity 110, and one end of the handle piece 300 is provided with a locking part 310, which is a key part for cooperating with the locking piece 400;

[0040] the locking piece 400 is movably connected with the handle shell 100, and the locking piece 400 is used for limiting the locking part 310; when the handle piece 300 is in the retracted state, the locking piece 400 can lock the locking part 310 to prevent the handle piece 300 from being accidentally unfolded;

[0041] the driving piece 500 is used for driving the locking piece 400 to move close to or away from the locking part 310, so as to realize the locking or unlocking of the handle piece 300.

[0042] Specifically, when the handle is needed to be used, the driving piece 500 drives the locking piece 400 to move away from the locking part 310, and the locking of the handle piece 300 is released, so that the handle piece 300 can be extended out of the accommodating cavity 110 through the folding linkage assembly 200. When it is not needed to be used, the handle piece 300 can be retracted into the accommodating cavity 110, and the driving piece 500 is driven to drive the locking piece 400 to move close to the locking part 310, so as to lock the handle piece 300. The cooperation between the locking piece 400 and the locking part 310 ensures that the handle piece 300 will not be accidentally unfolded in the non-use state, increases the safety and reliability of use, prevents the handle from being accidentally operated or falling off, and is especially suitable for application in occasions requiring high safety. The folding handle with the locking mechanism can effectively solve the problem that the traditional folding handle is easily accidentally operated or maliciously damaged in the non-use state, and greatly improves the safety and convenience of use.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the protection scope of the utility model.

[0044] Please refer to Figure 2 , the folding linkage assembly 200 comprises:

[0045] The first connecting piece 210 is rotatably connected to the through hole 120 of the handle housing 100. The first connecting piece 210 is connected to the through hole 120 of the handle housing 100 in a rotatable manner, and this rotatable connection allows the first connecting piece 210 to rotate within the through hole 120. The main function of the first connecting piece 210 is to serve as an interface for connecting a square shaft, which is usually a shaft with a square cross-section used in mechanical structures to transmit torque or as an axis of rotational motion. The first connecting piece 210 is designed with an internal structure that matches the square shaft, usually a square hole or groove, to tightly fit the shape of the square shaft. Through the connection with the square shaft, the first connecting piece 210 can drive the square shaft to rotate. More specifically, when the handle piece 300 is in the extended state, the user can rotate the handle piece 300 by twisting it, and the handle piece 300 can drive the first connecting piece 210 to rotate within the through hole 120 through the second connecting piece 220, thereby driving the square shaft to rotate. For example,

[0046] The second connecting piece 220 is rotatably connected to the first connecting piece 210 at its first end and to the handle piece 300 at its second end. The first end of the second connecting piece 220 is rotatably connected to the first connecting piece 210, which means that the first end of the second connecting piece 220 can rotate relative to the first connecting piece 210. The second end of the second connecting piece 220 is rotatably connected to the handle piece 300, which allows the handle piece 300 to rotate relative to the second end of the second connecting piece 220. For example, the second end of the second connecting piece 220 is rotatably connected to the handle piece 300 through the first pin 700, which serves as a rotation axis allowing the second connecting piece 220 to rotate relative to the handle piece 300. The first end of the second connecting piece 220 can be rotatably connected to the first connecting piece 210 through the second pin 800, which serves as a rotation axis allowing the second connecting piece 220 to rotate relative to the first connecting piece 210.

[0047] When the handle needs to be folded, the handle piece 300 can be rotated relative to the second connecting piece 220 by pushing the handle piece 300, and since the second connecting piece 220 is rotationally connected with the first connecting piece 210, the second connecting piece 220 will also rotate, and then the handle piece 300 drives the second connecting piece 220 to move into the accommodating cavity 110, realizing folding. Conversely, when the handle needs to be used, the handle piece 300 is reversely rotated by pulling the handle piece 300, and the second connecting piece 220 will also reversely move, so that the handle piece 300 extends out of the accommodating cavity 110, completing unfolding.

[0048] Please refer to Figure 2 , the folding linkage assembly 200 further comprises:

[0049] The first end of the first connecting piece 210 extends out of the handle shell 100 through the through hole 120, and the first end of the first connecting piece 210 is used for fixedly connecting with the third connecting piece 230. The third connecting piece 230 and the first end of the first connecting piece 210 can be firmly connected through bolts, screws or other fasteners, so as to ensure that they will not be loosened during operation.

[0050] The second end of the first connecting piece 210 is located in the accommodating cavity 110, and the second end of the first connecting piece 210 is provided with a protruding stepped portion 211. The edge of the through hole 120 is arranged in the space formed between the stepped portion 211 and the third connecting piece 230. The stepped portion 211 of the first connecting piece 210 is a protruding part which cooperates with the edge of the through hole 120. When the first end of the first connecting piece 210 passes through the through hole 120, the stepped portion 211 will abut against one side edge of the through hole 120. The third connecting piece 230 is located at the other side edge of the through hole 120 and is opposite to the stepped portion 211. When the third connecting piece 230 is fixedly connected with the first connecting piece 210, it will abut against the other side edge of the through hole 120. By fixing the third connecting piece 230 on the first connecting piece 210 and abutting both of them against the edge of the through hole 120, the first connecting piece 210 is effectively clamped in the through hole 120, preventing the first connecting piece 210 from moving in the axial direction. Since the first connecting piece 210 is fixed in the through hole 120, it can freely rotate in the through hole 120, but cannot move in the axial direction.

[0051] Please refer to Figure 2, the gasket 600 is arranged between the stepped portion 211 and the edge of the through hole 120, the first spring 231 and the ball 232 are arranged between the third connecting piece 230 and the edge of the through hole 120, one end of the first spring 231 is connected to the third connecting piece 230, the other end of the first spring 231 is connected to the ball 232 and the ball 232 abuts against the edge of the through hole 120. The gasket 600 is arranged between the stepped portion 211 and the edge of the through hole 120, which can reduce the direct friction between the two parts during rotation, thereby prolonging the service life of the components, and the ball 232 abuts against the edge of the through hole 120 under the action of the first spring 231, which can reduce the friction force when the third connecting piece 230 rotates relative to the edge of the through hole 120.

[0052] Please refer to Figure 2 , Figures 7 to 9 , the locking portion 310 is provided with one of a protrusion structure or a groove structure, the locking piece 400 is provided with the other one of the protrusion structure or the groove structure, and the protrusion structure is used for entering the groove structure to limit. One of the locking portion 310 and the locking piece 400 is provided with the protrusion structure, and the other one is provided with the groove structure. When the handle is folded, the protrusion structure can enter the groove structure, so that the position of the handle piece 300 is locked, and after the protrusion structure enters the groove structure, the handle piece 300 is limited in a specific position, preventing it from being accidentally unfolded or moved by external force in a non-use state. The cooperation of the protrusion structure and the groove structure is simple and effective, and provides reliable locking function.

[0053] Please refer to Figure 5 and Figure 6 , the driving piece 500 is provided with an eccentric boss 510, the locking piece 400 is provided with a connecting hole 410 matched with the eccentric boss 510, the eccentric boss 510 is arranged in the connecting hole 410, and the eccentric boss 510 abuts against the hole wall of the connecting hole 410 to drive the locking piece 400 to move when the driving piece 500 rotates. Specifically, the eccentric boss 510 is a non-central symmetric protruding part on the driving piece 500. When the driving piece 500 rotates, the eccentric boss 510 will produce an offset movement track because its position is not on the rotation axis. The connecting hole 410 on the locking piece 400 is designed to have a shape capable of accommodating the eccentric boss 510. When the eccentric boss 510 is located in the connecting hole 410, the rotational movement of the driving piece 500 will cause the eccentric boss 510 to move in the connecting hole 410. When the driving piece 500 rotates, the eccentric boss 510 moves in the connecting hole 410. Due to the offset movement of the eccentric boss 510, it will abut against the hole wall of the connecting hole 410, thereby pushing the locking piece 400 to move in a specific direction. By using the simple cooperation of the eccentric boss 510 and the connecting hole 410, complex mechanical movement conversion is realized, and the structure design is simple.

[0054] The movement of the locking member 400 changes its relative position with the locking portion 310, and realizes the function of locking or unlocking. For example, please refer to Figure 8 and Figure 9 When the locking member 400 moves to the position that makes the protruding structure separate from the groove structure, the handle member 300 can be unfolded; conversely, please refer to Figure 7 When the locking member 400 moves to the position that makes the protruding structure enter the groove structure, the handle member 300 is locked in the folded state.

[0055] Please refer to Figure 2 and Figure 3 The end of the second connecting member 220 close to the handle member 300 is provided with one of the first elastic limiting member 221 or the first limiting hole 320, and the side of the handle member 300 facing the second connecting member 220 is provided with the other one of the first elastic limiting member 221 or the first limiting hole 320, and the first elastic limiting member 221 is used for limiting with the first limiting hole 320. The first elastic limiting member 221 is a stretchable elastic element, usually made of spring or rubber and other materials, installed at the end of the second connecting member 220 close to the handle member 300. The first limiting hole 320 is a hole on the handle member 300 corresponding to the position of the first elastic limiting member 221, used for receiving the limiting part of the first elastic limiting member 221, when the handle member 300 is unfolded to the predetermined position, the first elastic limiting member 221 will enter the first limiting hole 320. This cooperation limits the further movement of the handle member 300, ensuring the stability and accuracy of the handle in the unfolded state.

[0056] Please refer to Figure 2 The first elastic limiting member 221 includes the second spring 222 and the first limiting member 223, the first limiting member 223 is connected to the first end of the second spring 222, the second connecting member 220 is provided with a connecting groove 224, the second spring 222 and the first limiting member 223 are connected in the connecting groove 224, and a part of the first limiting member 223 protrudes outward from the first end opening of the connecting groove 224. The second spring 222 is an elastic element, usually made of metal or other elastic materials, one end of which is connected to the first limiting member 223, and a part of the first limiting member 223 protrudes outward from the first end opening of the connecting groove 224, used for cooperating with the first limiting hole 320 on the handle member 300. The connecting groove 224 is a groove provided in the second connecting member 220, used for accommodating the second spring 222 and the first limiting member 223, and allowing a part of the first limiting member 223 to protrude outward from the first end opening of the connecting groove 224.

[0057] Please refer to Figure 2 and Figure 4The second elastic limiting member 225 is arranged on the end of the second connecting member 220 close to the first connecting member 210, and the second limiting hole 212 is arranged on the first connecting member 210 corresponding to the second elastic limiting member 225. When the first connecting member 210 rotates to a predetermined position, the second limiting member 226 enters the second limiting hole 212 of the first connecting member 210, which limits the further rotation of the first connecting member 210 and ensures the stability and accuracy of the handle member 300 at the specific position.

[0058] Please refer to Figure 2 The second elastic limiting member 225 includes a second limiting member 226 and a second spring 222, the second limiting member 226 is connected to the second end of the second spring 222, the second limiting member 226 is connected in the connecting groove 224, and a part of the second limiting member 226 protrudes outward from the second end opening of the connecting groove 224. The second limiting member 226 is a component connected to the second spring 222, and a part of the second limiting member 226 protrudes outward from the second end opening of the connecting groove 224, which is used to cooperate with the second limiting hole 212 on the first connecting member 210. When the first connecting member 210 rotates to a predetermined position, the second limiting member 226 enters the second limiting hole 212 of the first connecting member 210, which limits the further rotation of the first connecting member 210.
