Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 3:

the pulley poking type push-pull-button unlocking lockset provided by the embodiment of the invention comprises a handle connecting seat 1, a pulley poking assembly 2, a connector seat 3 and a push rod 4. The push rod 4 is a straight rod, can axially move and is inserted into the joint base 3 in an automatic reset mode, the outer end of the push rod is provided with a handle mounting base 41, and the inner end of the push rod is movably provided with a push inclined plane 42; the outer end that subassembly 2 was stirred to the pulley can vertically swing downwards and install on handle connecting seat 1 with automatic re-setting, and the inner tip is equipped with pulley 22, just subassembly 2 is stirred to the pulley can rotate and axial rotation along with handle connecting seat 1 rotates. The concrete structure can be as follows: the pulley poking component 2 comprises a poking bracket 21 and a pulley 22; the left side and the right side of the middle position of the toggle support 21 are provided with sunken pull tab buckle clamping positions 23, the side surface of the outer end and the upper part of the end part of the outer end are respectively provided with a rotating shaft hole 24 and a pulling lower swing driving part 25 which extends outwards in an inclined way, the inner end is provided with a pulley seat 26, and the pull tab buckle clamping positions 23, the rotating shaft hole 24, the pulling lower swing driving part 25 and the pulley seat 26 are integrally formed with the toggle support 21; when the handle is assembled, the toggle support 21 is longitudinally and rotatably arranged on the handle connecting seat 1 through the rotating shaft 27 penetrating through the rotating shaft hole 24, the lower swing driving part 25 is pulled to extend out of the outer end of the handle connecting seat 1, and the pull tab buckle is clamped on the pull tab buckle clamping position 23; the pulley 22 is rotatably mounted on the pulley seat 26 through a pulley shaft 28, and partially extends out of the pulley seat 26 to be in contact with the pushing inclined surface 42, as shown in fig. 2 and 3, the pulley seat 26 may be a recessed seat communicating with an inner end surface and an inner end upper surface of the toggle bracket 21, and when the pulley 22 is mounted in the pulley seat 26, a portion of the pulley extends out of the inner end surface and the inner end upper surface of the pulley seat 26. Moreover, one end of the push rod 4 inserted into the joint seat 3 is sleeved with a return spring 5, the peripheral side surface of the push rod is provided with a guide block 43, the corresponding position of the inner side of the joint seat 3 is provided with a matched guide groove 33 (as shown in fig. 2, the joint seat 3 comprises an inner seat 31 and an outer seat 32, the guide groove 33 is arranged on the inner seat 31, the outer seat 32 is sleeved on the inner seat 31), and the handle mounting seat 41, the pushing inclined surface 42 and the guide block 43 are integrally formed with the push rod 4; during assembly, two ends of the return spring 5 respectively support against the guide block 43 and the inside of the joint seat 3, and the guide block 43 can be clamped in the guide groove 33 in a reciprocating manner.

The working principle of the lockset of the invention is as follows: when a user pushes a handle arranged on the handle mounting seat 41 and acts on the push rod 4, the push rod 4 moves axially towards the pulley shifting assembly 2, the pulley shifting assembly 2 is driven to swing longitudinally downwards, the pull tongue fastener is driven to move longitudinally, the lock is unlocked (namely, a lock tongue of the pull tongue fastener is pulled and retracted, and a door can be pushed and opened), and meanwhile, the pulley 22 rolls obliquely downwards on the push inclined plane 42; when a handle arranged on the handle connecting seat 1 is pulled to act on the pulling lower swing driving part 25, the pulley shifting assembly 2 is driven to vertically swing downwards to drive the pull tongue fastener to vertically move, so that the lockset is unlocked (namely, a lock tongue of the pull tongue fastener is pulled and retracted, and a door can be pulled open); when the handle installed on handle connecting seat 1 is turned round, order about the pulley and stir 2 axial rotations of subassembly, drive the vertical motion of pull tab buckle, realize the tool to lock and open.

Therefore, the lockset can be opened in a pushing, pulling and twisting mode, the operation is flexible, convenient and quick, particularly when two hands are inconvenient, only one hand is needed to push the lockset through a handle of a body or other objects on the handle mounting seat 41, and meanwhile, the pulley poking component 2 and the push rod 4 adopt the transmission structure of the pulley 22 and the push inclined plane 42, so that the smoothness and the stability of pushing and opening are greatly ensured, the structure is very simple, the production and processing difficulty is low, the use and the installation are easy, and the popularization and the application are facilitated.
