[0051] The bolt 040 passes through the connecting portion 200 of the handle lock 010, the lock outer panel 020, the coil spring 050 and the square bar 030 and is connected to the emergency switch 060. The coil spring 050 is limited between the bolt 040 and the square bar 030.
[0052] The emergency switch 060 is located in the inner tube 210 of the other handle lock handle 010 .
[0053] In this embodiment, the structure of the entire handle lock matched with the handle lock handle 010 is provided. The structure of the specific lock outer panel 020 and the elastic member are all referred to the existing conventional design. The lock outer panel 020 is penetrated with a through hole 021 in the thickness direction, and various parts that conventionally realize the function of the lock body are arranged in the lock outer panel 020. The outer cylinder 220 of the handle lock handle 010 extends into the through hole 021 of the lock outer panel 020, and the elastic member is connected between the inner cylinder 210 and the lock outer panel 020. The function of the elastic member is to provide the force for the handle lock handle 010 to rotate. The inner end of the elastic member is fixed to the outer cylinder 220, and the outer end of the elastic member is fixed to the lock outer panel 020, so that the handle lock handle 010 is installed (after the square bar 030 passes through, the final positioning of the position is completed). Through the above structure, the handle lock handle 010 is directly installed, and a transition connector is no longer needed outside the elastic member.
[0054] The bolt 040 passes through a connecting portion 200 of a handle lock 010 , a coil spring 050 and a long channel and is then connected to an emergency switch 060 . The coil spring 050 is confined between the bolt 040 and the square bar 030 .
[0055] In one embodiment, the connecting portion 200 and the through hole 021 are clearance-fitted in the radial direction.
[0056] In this embodiment, the inner wall of the through hole 021 of the lock outer panel 020 does not come into contact with the connecting portion 200 , thereby reducing the friction between the lock outer panel 020 and the handle lock handle 010 .
[0057] In one embodiment, a step structure is provided at the connection between the outer tube 220 and the inner tube 210 , so as to limit the emergency switch 060 from escaping from the outer tube 220 .
[0058] In this embodiment, considering that the bolt 040 is connected to the emergency switch 060, a step structure is provided at the connection between the outer tube 220 and the inner tube 210, and the emergency switch 060 is installed from the inner tube 210, but is restricted by the step structure and cannot be removed from the outer tube 220. The bolt 040 and the square bar 030 are fixed in one direction.
[0059] In one embodiment, a gasket is further included, and the gasket is clamped between the coil spring 050 and the square bar 030 .
[0060] In this embodiment, the force of the coil spring 050 is received by the gasket, so as to avoid direct action between the coil spring 050 and the square bar 030, and reduce the probability of the coil spring 050 being loosened from the square bar 030. The material of the gasket can be stainless steel, etc., which is not limited here.
[0061] In one embodiment, the inner tube 210 and the emergency switch 060 form a circumferential limitation.
[0062] In this embodiment, the inner tube 210 and the emergency switch 060 are fixed in the circumferential direction, so that after the emergency switch 060 is installed in the inner tube 210, the emergency switch 060 will not rotate abnormally. Specifically, the outer circumferential shape of the emergency switch 060 and the inner circumferential shape of the inner tube 210 are circumferentially clamped, so that the emergency switch 060 will not rotate after installation. Generally, the square bar 030, the bolt 040, the coil spring 050 and the emergency switch 060 are pre-connected and then assembled as a whole; and the above circumferential limitation of the emergency switch 060 makes the bolt 040 convenient in the subsequent installation process.
[0063] To sum up, the handle lock handle and handle lock provided by the utility model have a connecting part directly formed on the main body, and the connection with the lock outer panel is achieved through the external tube on the connecting part, and the connection with the square strips in the lock outer panel is achieved through the internal tube on the connecting part; the setting of the integral structure of the connecting part and the main body reduces the difficulty of processing and installing the handle lock handle.
[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
