Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, and in particular to a compact lock. Background Technology

[0002] With the increasing popularity of outdoor sports such as mountaineering and hiking, trekking poles, as important auxiliary equipment, are receiving increasing attention from users for their lightweight, portability, and reliability. Multi-section folding trekking poles are widely used due to their ease of storage and adjustment. Their core locking mechanism needs to provide stable support when unfolded and prevent accidental retraction under stress; the locking mechanism directly affects safety and user experience. Folding trekking poles using rotating bushings or threaded locking methods are at risk of wear and tear during use.

[0003] Chinese utility model patent CN222425500U discloses an external locking mechanism for trekking poles and a trekking pole. The external locking mechanism includes: a buckle for fitting onto the end of the outer pole, the buckle having a first end and a second end opposite to each other, with an axial locking gap between the first end and the second end; a wrench, one end of which is hinged to the first end of the buckle; and a connecting arm, one end of which is hinged to the middle of the wrench, and the other end of which is hinged to the second end of the buckle. Although this design improves the ease of operation and locking force, its hinge points are distributed at both ends of the buckle and the middle of the wrench, resulting in a large overall structural space occupation, which is difficult to meet the current demand for lightweight outdoor equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lock with a compact structure, which concentrates the hinge points to make the structure compact and suitable for current lightweight outdoor activities.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a compact lock includes a locking ring, a connecting member, and a wrench. The locking ring is integrally provided with a first mounting seat and a second mounting seat. The connecting member has a first mounting hole, a circular arc-shaped hole, and a straight circular arc-shaped hole. The hinge end of the wrench has a first connecting hole and a second connecting hole. The first connecting hole and the first mounting hole are rotatably connected by a pin. The first mounting seat, the circular arc-shaped hole, and the second connecting hole are movably connected by a pin. The wrench moves in the circular arc-shaped hole. The second mounting seat is movably connected to the straight circular arc-shaped hole by a pin. The second mounting seat moves within the straight circular arc-shaped hole. When the wrench is rotated away from the locking ring, the connecting member moves towards the force-applying end of the wrench, and the second mounting seat moves within the straight circular arc-shaped hole, causing the locking ring to be in an open state. When the user rotates the wrench towards the locking ring, the connecting member moves towards the hinge end of the wrench, and the second mounting seat abuts against the edge of the straight circular arc-shaped hole, causing the locking ring to be in a tightened state.

[0006] Furthermore, the hinge end of the wrench is a U-shaped groove, and a first connecting hole and a second connecting hole are provided on the U-shaped groove, with the connector located inside the U-shaped groove.

[0007] Furthermore, the force-applying end of the wrench is integrally provided with a pressing plate whose width is greater than that of the U-shaped groove, and the pressing plate is provided with a pattern to increase friction.

[0008] Furthermore, the center of the first mounting hole, the center of the lower half of the arc-shaped hole, and the centerline of the straight waist-shaped hole are all located on the same horizontal line on the connector.

[0009] Furthermore, the first mounting base and the second mounting base are arranged along the locking ring, and the gap between the first mounting base and the second mounting base is the locking gap.

[0010] Furthermore, the locking ring is provided with a weight-reducing groove, which reduces the weight.

[0011] Compared with the prior art, the advantages of this utility model are that the straight waist-shaped hole, the mounting hole and the hinge point of the wrench on the connector are arranged in a centralized layout, which greatly integrates the hinge structure, reduces the volume and space occupation of the entire lock, and is more in line with the lightweight requirements of modern outdoor equipment such as trekking poles; in addition, the addition of a patterned pressing plate increases the friction during operation, making it easy to apply force even when wearing gloves or in wet and slippery environments, making it suitable for outdoor use.

[0012] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0013] Figure 2 This is a front view of the present invention;

[0014] Figure 3 This is an exploded view of the present invention. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-3As shown, a compact lock includes a locking ring 1, a connector 2, and a wrench 3. The locking ring 1 has an integrally formed first mounting base 11 and a second mounting base 12, which are positioned along the locking ring 1. A locking gap 13 is provided between the first mounting base 11 and the second mounting base 12. A weight-reducing groove 14 is provided on the locking ring 1 to reduce the weight of the lock, meeting the lightweight requirements of modern outdoor equipment. The connector 2 has a first mounting hole 21, an arc-shaped waist-shaped hole 22, and a straight waist-shaped hole 23. The center of the first mounting hole 21 and the arc-shaped waist-shaped hole... The center of the lower semicircular arc of 22 and the center line of the straight waist-shaped hole 23 are both located on the same horizontal line on the connector 2. This design concentrates all hinge points on the connector 2, effectively reducing the volume of the latch. The hinge end of the wrench 3 is a U-shaped groove 31, on which a first connecting hole 32 and a second connecting hole 33 are provided. The first connecting hole 32 is rotatably connected to the first mounting hole 21 by a pin. The first mounting seat 11, the arc-shaped waist-shaped hole 22, and the second connecting hole 33 are movably connected by a pin. The hinge end of the wrench 3 slides in the arc-shaped waist-shaped hole 22. The second mounting seat 12... The second mounting base 12 is movably connected to the straight oblong hole 23 via a pin. It moves horizontally within the straight oblong hole 23, employing a movable connection method where the straight oblong hole 23 and the second mounting base 12 cooperate. The movement of the connecting piece 2 is directly driven by rotating the wrench 3. When the lock is tightened, the second mounting base 12 firmly abuts against the edge of the straight oblong hole 23, avoiding play and loosening caused by wear at multiple dispersed hinge points, ensuring locking force and reliability over long-term use. The connecting piece 2 is located within the U-shaped groove 31, and the force-applying end of the wrench 3 is integrally provided with a width greater than the U-shaped groove. The pressing plate 34 of 31 has a pattern 35 to increase friction, making it easy to apply force even when wearing gloves or in wet and slippery environments, suitable for outdoor activities. When the wrench 3 is turned away from the locking ring 1, the connecting piece 2 moves toward the force-applying end of the wrench 3, and the second mounting seat 12 moves within the straight waist-shaped hole 23, so that the locking ring 1 is in the open state. When the user turns the wrench 3 toward the locking ring 2, the connecting piece 2 moves toward the hinge end of the wrench 3, and the second mounting seat 12 abuts against the edge of the straight waist-shaped hole 23, so that the locking ring 1 is in the tightened state.

[0017] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
