[0002] To ensure mountaineering safety, climbers need to be equipped with multiple harnesses. In order to accommodate climbers of different systems, existing technologies design buckle structures at the ends of the harnesses. However, since the directions of multiple harnesses are different, there are many locking structures that need to be designed. They need to be connected and disconnected multiple times when wearing them, which is not very convenient. Utility Model Content

[0003] The purpose of this application is to provide a composite locking structure for mountaineering that is safer and easier to put on and take off.

[0004] To achieve the above objectives, this application provides a composite locking structure for mountaineering: including a cover, a buckle body, and a shell with an open rear end. The front end of the shell has a clearance opening that passes through the front and rear ends. A lock cylinder is provided inside the shell. The lock cylinder includes a sliding plate. The front of the sliding plate has a blocking block, and the front of the blocking block has an unlocking button, which is suitable for cooperating with the clearance opening to form a sliding pair. The front of the sliding plate also has four locking hooks, which are equidistantly arranged around the blocking block. Each locking hook has a claw at the end facing away from the sliding plate, and the claw extends in the direction of the blocking block. The four side walls of the shell all have insertion interfaces that pass through the inner and outer walls, allowing a plug plate to pass through and cooperate with the lock cylinder.

[0005] The cover is fixedly connected to the rear open end of the housing. A spring is provided between the cover and the lock cylinder. The buckle body includes a shoulder strap buckle, a crotch strap buckle and two waist belt buckles. Each of these buckle bodies includes a plug plate. The plug plate is adapted to pass through the plug interface and engage with the lock hook. One end of the plug plate located outside the housing is connected to a connecting buckle, which is always located outside the housing and is used to connect with the seat belt.

[0006] As a preferred embodiment, the plug plate has a fitting opening, which is suitable for the locking hook to pass through, forming a locking and limiting structure.

[0007] As a preferred embodiment, the side of the locking hook facing the blocking block is the outer blocking surface, the side of the locking hook facing away from the blocking block is the sliding out ramp, and the side of the hook facing the blocking block is the sliding in ramp; the end of the plug plate facing away from the connecting buckle has an outer ramp, which is suitable for fitting with the sliding out ramp to form a sliding pair; the inner wall of the fitting opening away from the connecting buckle is an inner plane, which is suitable for fitting with the outer blocking surface; and the inner wall of the fitting opening close to the connecting buckle is an inner ramp, providing more space for the sliding out ramp of the locking hook.

[0008] As a preferred embodiment, the buckle has a strap opening, and the safety belt and buckle are not fixed, so the length of the safety belt can be flexibly adjusted according to the climber's body size.

[0009] As a preferred embodiment, the housing includes a rectangular limiting plate, the clearance opening extends through the front and rear surfaces of the limiting plate, the edge of the limiting plate has an engagement frame, the four insertion ports respectively penetrate the four side walls of the engagement frame, the sliding plate is cuboid in shape, and the four outer sides of the sliding plate are adapted to fit against the four inner walls of the housing to form a sliding pair, ensuring the stability of the lock cylinder sliding within the housing.

[0010] As a preferred embodiment, the cover includes a back panel with an insert on the front side adapted to be fitted into the rear opening of the housing, thereby restraining moving parts within the housing.

[0011] As a preferred embodiment, the front of the insert plate is provided with a first configuration groove, and the back of the slide plate is provided with a second configuration groove extending into the blocking block. One end of the spring is embedded in the first configuration groove, and the other end is embedded in the second configuration groove to ensure the connection stability of the two ends of the spring.

[0012] As a preferred embodiment, the cover has a first inner handle in the first configuration slot, which is suitable for being embedded in one end of the spring; the lock cylinder has a second inner handle in the second configuration slot, which is suitable for being embedded in the other end of the spring, thereby further improving the fit between the two ends of the spring and the lock cylinder and the cover.

[0013] As a preferred embodiment, the locking hook, sliding plate, and blocking block are an integral structure made of stainless steel, and the plug plate is also made of stainless steel, which can withstand a large load.

[0014] As a preferred option, both the cap and the cover are made of plastic, which does not bear a large load and has better lightweight and aesthetic appeal.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] (1) By designing a lock cylinder structure with four locking hooks, the buckle body can be locked and unlocked simultaneously in four directions. When wearing the safety belt, it is not necessary to connect each one individually, and when removing it, it is not necessary to unlock each one individually. Therefore, this composite buckle is faster and more convenient when wearing and removing mountaineering safety belts.

[0017] (2) By designing a claw structure at the end of the lock hook, the plug plate is prevented from sliding out of the end of the lock hook. Even if the unlocking button is accidentally pressed during the mountain climbing process, the plug body will not separate from the lock hook, which can effectively ensure the restraint of the mountain climbing leader during the mountain climbing process. This composite lock structure is safe and reliable. Attached Figure Description

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0033] like Figure 1-10The composite locking structure for mountaineering shown includes a cover 1, a snap-fit ​​body 4, and a shell 2 with an open rear end. Since the cover 1 and the snap-fit ​​body 4 do not need to bear a large load, they can both be made of plastic. The front end of the shell 2 has a clearance opening 203 that passes through the front and rear ends. A lock cylinder 5 is installed inside the shell 2. The lock cylinder 5 specifically includes a sliding plate 501. A blocking block 502 is located in the center of the front of the sliding plate 501. An unlocking button 505 is located on the front of the blocking block 502, which corresponds to the clearance opening 203. 3. The sliding pair is formed by the cooperation of the sliding plate 501 and the front of the sliding plate 501. The four locking hooks 560 are arranged equidistantly around the blocking block 502. The locking hooks 560, the sliding plate 501 and the blocking block 502 are integrated structures made of stainless steel and can withstand large loads. Each locking hook 560 has a claw 561 at the end facing away from the sliding plate 501. The claw 561 extends in the direction of the blocking block 502 and is used to prevent the structure that cooperates with the locking hook 560 from sliding out from the end of the locking hook 560.

[0034] The four side walls of the housing 2 are provided with insertion interfaces 204 that penetrate the inner and outer walls. In fact, the housing 2 includes a rectangular limiting plate 201. The clearance opening 203 penetrates the front and rear surfaces of the limiting plate 201. The edge of the limiting plate 201 has an engagement frame 202, which makes the housing 2 also rectangular. The four insertion interfaces 204 penetrate the four side walls of the engagement frame 202 respectively, in four directions: up, down, left, and right. The four locking hooks 560 correspond to the directions of the four insertion interfaces 204. The sliding plate 501 is also rectangular, but flatter. The four outer sides of the sliding plate 501 are used to fit against the four inner walls of the housing 2 to form a sliding pair, which improves the stability of the lock cylinder 5 sliding in the housing 2. The blocking block 502 is also rectangular, and its side is parallel to the side of the sliding plate 501.

[0035] The cover 1 is fixedly connected to the rear open end of the housing 2. The specific structure of the cover 1 includes a cuboid back plate 101. The cross-sectional dimensions of the back plate 101 are the same as those of the housing 2. The outer side of the back plate 101 is aligned with the outer side of the housing 2. The front of the back plate 101 has an insert plate 102 for being embedded in the rear open end of the housing 2 and being clamped and fixed.

[0036] A spring 3 is provided between the cover 1 and the lock cylinder 5. The spring 3 is pre-compressed and has a tendency to extend. The front of the inner plate 102 has a first configuration groove 103. One end of the spring 3 is embedded in the first configuration groove 103. The cover 1 is provided with a first inner handle 104 in the first configuration groove 103 for embedding in one end of the spring 3 to ensure stable cooperation between the spring 3 and the cover 1. The back of the slide plate 501 has a second configuration groove 503 extending into the blocking block 502. The other end is embedded in the second configuration groove 503. The lock cylinder 5 is provided with a second inner handle 504 in the second configuration groove 503 for embedding in the other end of the spring 3 to ensure stable cooperation between the spring 3 and the lock cylinder 5. In this way, both ends of the spring 3 are constrained, and its position in the housing 2 remains stable.

[0037] The buckle body 4 includes a shoulder strap buckle 410, a crotch strap buckle 430, and two waist belt buckles 420. The shoulder strap buckle 410 engages with the upper insertion interface 204, the crotch strap buckle 430 engages with the lower insertion interface 204, and the two waist belt buckles 420 engage with the left and right insertion interfaces 204 respectively. The shoulder strap buckle 410, crotch strap buckle 430, and waist belt buckles 420 have the same structure and are collectively referred to as buckle bodies 4. All buckle bodies 4 include a plug plate 401. Since the plug plate 401 needs to engage with the locking hook 560 to withstand a large load, it is also made of stainless steel.

[0038] Each connector plate 401 needs to pass through the connector 204 and engage with the hook 560. The connector plate 401 has an engagement opening 403 for the hook 560 to pass through and form a limiting structure. The side of the hook 560 facing the blocking block 502 is the outer blocking surface 563, which is located between the hook 561 and the slide plate 501 and is parallel to the outer side of the blocking block 502. The side of the hook 560 facing away from the blocking block 502 is the sliding ramp 564, which gradually approaches the blocking block 502 in a direction away from the slide plate 501. 1. One side of the blocking block 502 is a sliding ramp 562, which gradually moves away from the blocking block 502 in a direction away from the slide plate 501; the end of the plug plate 401 facing away from the buckle 402 has an outer ramp 405, which can fit with the sliding ramp 564 to form a sliding pair; the inner wall of the mating opening 403 away from the buckle 402 is an inner plane 406, which is used to fit with the outer blocking surface 563; the inner wall of the mating opening 403 near the buckle 402 is an inner ramp 407, which is parallel to the sliding ramp 564, thus giving more space to the locking hook 560.

[0039] The end of the plug plate 401 located outside the housing 2 is connected to a strap buckle 402, which has a strap opening 404 for the mountaineering safety belt to pass through.

[0040] Working principle: In use, first pass the shoulder safety belt through the strap opening 404 of the shoulder belt buckle 410, pass the waist safety belt through the strap opening 404 of the waist belt buckle 420, and pass the crotch safety belt through the strap opening 404 of the crotch belt buckle 430. Then, insert the insertion plates 401 of the four buckle bodies 4 into the four corresponding insertion ports 204 on the housing 2. This will simultaneously apply a force to the four buckle bodies 4 in the direction of the housing 2. The four insertion plates 401 will slide across the inclined surface 564 at the same time, forcing the slide plate 501 to move closer to the cover 1. When the hook 561 passes the engagement port 404, When the inner plane 406 of 3 is in contact with the spring 3, the lock cylinder 5 moves away from the cover 1 under the action of the spring 3, and the lock hook 560 slides into the engagement port 403 and finally is located between the slide plate 501 and the hook 561. Then adjust the tightness of the shoulder belt, waist belt and crotch belt so that the inner plane 406 of all the plug plates 401 is in contact with the outer blocking surface 563 of the corresponding lock hook 560. In this way, even if the unlocking button 505 is pressed during the climbing process, the hook 561 can prevent the lock hook 560 from disengaging from the engagement port 403 of the plug plate 401, thereby maintaining the locking stability of the buckle body 4.

[0041] When the hike is complete and the wearer needs to remove their equipment in a safe area, they simply apply a force to all four buckle bodies 4 in the direction of the housing 2. This causes the inner plane 406 of the plug plate 401 to separate from the outer blocking surface 563 of the hook 560. Once the hook 561 no longer blocks the plug plate 401, the unlock button 505 can be pressed to overcome the elasticity of the spring 3, allowing the slide plate 501 to move closer to the cover 1 until the hook 560 disengages from the engagement port 403 of the plug plate 401. Releasing the unlock button 505 causes the outer inclined surface 405 of the plug plate 401 to engage with the sliding inclined surface 564. The spring 3 pushes the unlock button 505 back to its original position, and the hook 560 pushes all the plug plates 401 away from the housing 2 through the sliding inclined surface 564, thus completing the unlocking and separation of all the buckle bodies 4.

[0042] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
