Description

TECHNICAL FIELD

[0001] The utility model relates to mountaineering pole telescopic rod locking technical field, specifically a mountaineering pole locking buckle. BACKGROUND

[0002] In order to reduce space when receiving, many products will use telescopic rod structure, such as mountaineering pole, camera support and so on, at the same time, in order to keep the extended state, locking buckle structure is arranged at the connecting place of telescopic structure.

[0003] The traditional locking buckle structure adopts C-shaped structure, a lock rod is arranged at the C-shaped opening, a wrench is arranged at one end of the lock rod, a protruding part is arranged on the wrench, the protruding part is abutted against the locking buckle body when locking, the lock rod is pulled outward by using reaction, so that the C-shaped opening of the locking buckle body is tightened to realize locking. The similar structure is adopted in the patent application with the application number CN201821008893.4 and the name "a quick locking structure for mountaineering pole", but the locking buckle of this kind of structure generally needs to be used with a sleeve, and the locking force is small, and locking failure may occur after long-term use.

[0004] Another patent application with the application number CN202320826116.5 and the name "a locking device for mountaineering pole" discloses a locking device, which comprises a lock sleeve, a lock buckle movably connected to the lock sleeve, a wrench movably connected to the lock buckle, and the wrench is movably connected to the lock sleeve; when the wrench is rotated to abut against the lock sleeve in the direction away from the lock buckle, the clamping inner diameter of the lock sleeve becomes smaller. The locking device uses the hinge joint between the wrench and the lock buckle as a fulcrum, one end of the lock sleeve is tightened by the end of the wrench, so that the clamping inner diameter becomes smaller to realize locking; compared with the traditional locking buckle structure, the locking force of the locking device is improved, but the essence is still to tighten the C-shaped opening by the wrench to realize locking, the locking force is limited, and in the locking process, the lock buckle part is subjected to large stress (the hinge seat part of the lock buckle is subjected to large tension), and is easy to break.

[0005] In order to overcome the above defects, a locking buckle is designed, as disclosed in the patent application with the application number CN202420260152.4 and the name "a locking buckle structure", which comprises a locking body, the locking body comprises a first end and a second end, the first end and the second end cross to extend so that the locking body is in a ring structure, the first end is hinged to one end of a connecting piece, the second end is hinged to one end of a wrench, and the connecting piece is hinged to the inner side of the second end and the wrench hinge. In the subsequent production and use, in order to avoid the connecting piece in the middle, a part of the wrench needs to be sacrificed, which leads to the need of large force when locking, and the structure still has improvement space.

[0032] As shown in Figures 1 to 5 A mountaineering pole locking buckle, comprising a locking body 1, the locking body 1 comprises a first end 11 close to a wrench 3 and a second end 12 away from the wrench 3, the first end 11 and the second end 12 cross-extend so that the locking body 1 is annular, the second end 12 is hinged with one end of a connecting piece 2, the first end 11 is hinged with the wrench 3, the inner side of the wrench 3 at the hinged place of the first end 11 and the wrench 3 is provided with a connecting part 3a, the other end of the connecting piece 2 is hinged with the connecting part 3a of the wrench 3.

[0033] The wrench 3 comprises an operating part 31 in arc structure, the rear end of the operating part 31 is provided with a pair of connecting seats 32, the connecting seats 32 vertically extend inward to form the connecting part 3a.

[0034] The inner surface of the operating part 31 is formed with a first arc surface 31a, when the locking buckle is locked, the first arc surface 31a is attached to the locking body 1 (as shown in Figure 5 In this way, when locked, the structure of the locking buckle is more compact, and the occupied space is smaller.

[0035] The outer surface of the operation part 31 is formed with a second arc surface 31b, and the end surface of the operation part 31 is provided with an inwardly inclined wrenching surface 31c. When the locking buckle is unlocked, the user needs to wrench the wrench 3. Here, the inwardly inclined wrenching surface 31c is provided to facilitate the force exerted by the wrench 3, and the unlocking operation can be more labor-saving. The operation part 31 is in a circular arc structure, and when locked, it can be forced along the second arc surface 31b, which is more convenient and handy.

[0036] One end of the connecting piece 2 is provided with a pair of hinge seats 21, and the second end portion 12 is arranged between the pair of hinge seats 21.

[0037] The locking body 1 is provided with two first end portions 11, and the wrench 3 is arranged between the two first end portions 11.

[0038] The wrench 3 is provided with two connecting portions 3a, and the other end of the connecting piece 2 is arranged between the two connecting portions 3a.

[0039] The second end portion 12 is rotationally connected with the connecting piece 2 through a first rotating shaft 41, the wrench 3 is rotationally connected with the first end portion 11 of the locking body 1 through a second rotating shaft 42, and the connecting piece 2 is rotationally connected with the wrench 3 through a third rotating shaft 43.

[0040] The second end portion 12 is provided with an adjusting groove 12a, and the first rotating shaft 41 passes through the adjusting groove 12a. The second end portion 12 is provided with an adjusting member 5 for adjusting the locking force, and the inner end of the adjusting member 5 can extend into the adjusting groove 12a.

[0041] The adjusting member 5 is an adjusting screw, and the adjusting screw is threadedly connected with the second end portion 12.

[0042] By adjusting the extension length of the adjusting member 5, the distance between the first rotating shaft 41 and the second rotating shaft 42 can be adjusted, so as to adjust the locking stroke and achieve the purpose of adjusting the locking force. Figure 1 In order to show the installation position of the adjusting screw, it extends out of the second end portion 12. In the actual product application process, the outer end of the adjusting screw is retracted into the second end portion 12, which can avoid the safety hazard of scratching the user caused by the exposure of the adjusting screw.

[0043] Working principle:

[0044] The locking buckle is fixed at the connection of the telescopic rod of the mountain climbing stick, and when the extension length of the telescopic rod is adjusted, the buckle is downed by the wrench 3, and the locking is convenient. When the buckle is downed by the wrench 3, the user presses the operation part 31 of the wrench 3, so that the wrench 3 rotates around the second rotating shaft 42, the connecting part 3a of the wrench 3 is lifted along with the operation part 31 approaching the locking body 1, the connecting part 2 is driven to move away from the wrench 3 (the connecting part 2 is pressed down), since the one end of the connecting part 2 away from the wrench 3 is hinged with the second end part 12 of the locking body 1, the connecting part 2 will drive the second end part 12 to move away from the first end part 11, and the circumference of the annular part of the locking body 1 is reduced, so that the locking purpose is achieved. When unlocking, the wrench 3 is only rotated away from the locking body 1, and the wrench 3 is pulled up.

[0045] It is worth noting that the locking buckle structure of the utility model, when the wrench 3 is pressed down for locking, the connecting part 2 is pressed down at the same time, so that the cavity is set on the wrench 3 for avoiding the connecting part 2 from being lifted up when the wrench 3 is pressed down for locking, the pressing area (the operation part 31) on the wrench 2 is larger, the locking pressing is more labor-saving, and the pressing is more convenient and handy.

[0046] The above is only the preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model, and for the person skilled in the art, it should be realized that the obtained scheme of the equivalent replacement and the obvious change of the application specification and the drawing content should be contained in the protection scope of the utility model.
