Description

Technical Field

[0001] This utility model belongs to the technical field of mining equipment, specifically relating to a mining walkie-talkie lanyard. Background Technology

[0002] In the complex and harsh working environment of mines, walkie-talkies are an indispensable key device for ensuring personnel communication and production safety.

[0003] Miners typically attach walkie-talkies to their belts or clothing using simple plastic clips, or place them directly in their pockets. These methods of carrying walkie-talkies have significant drawbacks: First, the simple clip structure is unreliable. When the walkie-talkie is in a pocket, it is very easy for it to fall out when the worker bends over, climbs, or traverses narrow areas, leading to loss or damage. This not only causes property damage but may also lead to serious safety accidents due to communication interruption. Utility Model Content

[0004] This application proposes a lanyard for mining walkie-talkies, which can be used to carry walkie-talkies and prevent them from falling during transport, thereby improving the stability of the walkie-talkies when carried.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mining walkie-talkie lanyard includes a fixing buckle with a locking structure. The locking structure includes a groove and a slot within the fixing buckle, a pin slidably disposed within the groove, and a spring disposed within the groove. The pin has a lever extending outward through an opening in the fixing buckle. One end of the pin is connected to the spring, and the other end is inserted into the slot. A hanging ring is fitted onto the fixing buckle and connected to one end of a first connecting rope. The other end of the first connecting rope is connected to a first magnetic snap fastener, which is used to attract a second magnetic snap fastener. The second magnetic snap fastener is connected to one end of a second connecting rope, and the other end of the second connecting rope is connected to a protective box.

[0006] In one embodiment of this application, the outer wall of the paddle block is a smooth curved surface.

[0007] In one embodiment of this application, the pin has a pointed end in the slot.

[0008] In one embodiment of this application, the outer ring of the first magnetic snap is provided with a sleeve, and the first magnetic snap and the second magnetic snap are attracted to each other inside the sleeve.

[0009] In one embodiment of this application, the bottom of the protective box is provided with a sliding cover.

[0010] In one embodiment of this application, magnetic strips are provided on the side wall of the bottom opening of the protective box and the insertion end of the sliding cover, respectively.

[0011] In one embodiment of this application, the outer walls of the first connecting rope and the second connecting rope are covered with a nylon layer.

[0012] In summary, the technical solution proposed in this application includes the following beneficial technical effects: This application uses a notch to nest the fixing buckle in a position such as a belt that is carried on the body. Releasing the spring in the sliding groove of the lever pushes the pin to re-insert into the slot, thereby closing the notch of the fixing buckle and realizing the closed engagement of the fixing buckle. Further, a hanging ring is sleeved on the fixing buckle. The hanging ring is connected to one end of the first connecting rope, and the other end of the first connecting rope is connected to the first magnetic buckle. The first magnetic buckle is used to attract a second magnetic buckle. The second magnetic buckle is connected to one end of the second connecting rope, and the other end of the second connecting rope is connected to the protective box. The protective box is used to hold the walkie-talkie and protect its safety. The first connecting rope and the second connecting rope are connected by the magnetic buckle. On the one hand, the magnetic buckle facilitates connection and assembly. On the other hand, if the protective box containing the walkie-talkie gets stuck during operation, the magnetic buckle can be pulled out to disconnect the connecting rope for easy release, preventing the walkie-talkie from falling during carrying, thereby improving the stability of the walkie-talkie when carried.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0019] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0020] This embodiment provides a mining walkie-talkie lanyard, see reference. Figures 1-5As shown, the device includes a fixing buckle 1 with a locking structure. The locking structure includes a groove 2 and a slot 23 within the fixing buckle 1, a pin 21 slidably disposed within the groove 2, and a spring 22 disposed within the groove 2. The pin 21 has a lever 211 extending outward through an opening 11 on the fixing buckle 1. One end of the pin 21 is connected to the spring 22, and the other end of the pin 21 is inserted into the slot 23 of the fixing buckle 1. A hanging ring 3 is fitted onto the fixing buckle 1. The hanging ring 3 is connected to one end of a first connecting rope 4, and the other end of the first connecting rope 4 is connected to a first magnetic snap 41. The first magnetic snap 41 is used to attract a second magnetic snap 51. The second magnetic snap 51 is connected to one end of a second connecting rope 5, and the other end of the second connecting rope 5 is connected to a protective box 6.

[0021] In the above embodiment, the fastener 1 is arranged in a circular shape, with a notch and a sliding groove 2. A pin 21 is arranged in the sliding groove 2, and a lever 211 is arranged on the pin 21. The lever 211 extends out of the sliding groove 2 through the opening 11 on the fastener 1. One end of the pin 21 is connected to a spring 22, and the other end of the pin 21 is inserted into the slot 23 of the fastener 1. In the initial state, the spring 22 pushes the pin 21 into the slot 23, and pushes the lever 211 to compress the spring 22, causing the pin 21 to retract in the sliding groove 2 and pull the pin 21 out of the slot 23, so that the notch on the fastener 1 opens. It can be used to nest the fastener 1 in a position such as a belt that is carried on the body through the notch. When the lever 211 is released, the spring 22 in the sliding groove 2 pushes the pin 21 back into the slot 23, so that the notch of the fastener 1 closes, thereby realizing the closed sleeve of the fastener 1. Furthermore, a hanging ring 3 is fitted onto the fixing buckle 1. The hanging ring 3 is connected to one end of the first connecting rope 4, and the other end of the first connecting rope 4 is connected to the first magnetic snap 41. The first magnetic snap 41 is used to attract the second magnetic snap 51, which is connected to one end of the second connecting rope 5. The other end of the second connecting rope 5 is connected to the protective box 6, which is used to hold the walkie-talkie and protect its safety. The first connecting rope 4 and the second connecting rope 5 are connected by magnetic snaps. On the one hand, the magnetic snaps facilitate connection and assembly; on the other hand, if the protective box 6 containing the walkie-talkie gets stuck during operation, the magnetic snaps can be pulled out to disconnect the connecting rope for easy removal.

[0022] In one embodiment of this application, see reference Figure 4 As shown, the outer wall of the paddle 211 is a smooth curved surface.

[0023] In the above embodiments, the outer wall of the paddle 211 adopts a smooth-transition curved surface shape (e.g., spherical or elliptical). The paddle 211 is in frequent contact with work clothes, and the smooth curved surface can significantly reduce snagging and wear on the clothing fabric, eliminating the potential risk of sharp edges causing scratches to the human skin.

[0024] In one embodiment of this application, see [reference] Figure 3 As shown, the pin 21 has a pointed end in the slot 23.

[0025] In the above embodiments, when the worker is not wearing a belt or the belt is not suitable for hanging, the fixing buckle 1 can be directly fixed to a thicker work uniform (such as canvas or thick cotton) or the woven belt of the equipment. The pointed end of the pin 21 is designed to have a certain piercing ability, which can penetrate into the gaps between the fabric fibers, thereby achieving a temporary but relatively firm fixation. When the buckle is closed, the pointed end of the pin 21 is inserted into the slot 23 to prevent the pointed end from piercing the person.

[0026] In one embodiment of this application, see reference Figure 6 As shown, the outer ring of the first magnetic snap 41 is provided with a sleeve 411, and the first magnetic snap 41 and the second magnetic snap 51 are attracted to each other inside the sleeve 411.

[0027] In the above embodiment, the sleeve 411 encloses the mutually adsorbed portions of the first magnetic buckle 41 and the second magnetic buckle 51. The inner wall of the sleeve 411 guides and limits the magnetic buckles, restricting their precise alignment and separation along the axial direction (adsorption direction) of the sleeve 411, thus resisting lateral slippage and detachment caused by lateral tension or shear force. Furthermore, the sleeve 411 is made of a non-magnetic material (such as plastic), preventing the sleeve 411 itself from becoming a magnet, thereby preventing the entire lanyard from accidentally adsorbing onto iron pipes, equipment, or supports in the mine, eliminating the risk of entanglement.

[0028] In one embodiment of this application, see reference Figure 3 As shown, the bottom of the protective box 6 is provided with a sliding cover 61.

[0029] In the above embodiment, the sliding cover 61 is connected to the bottom of the protective box 6 via a track. During use, simply pushing or pulling the sliding cover 61 along the track opens or closes the opening of the protective box 6. This linear motion is simpler, more direct, and faster than a flip cover requiring alignment or a snap-fit ​​mechanism requiring both hands. It is suitable for working conditions where miners may wear gloves or have dirty hands, requiring no fine movements or forceful pressing. Furthermore, the sliding structure is generally more durable and has a longer service life than a hinged flip cover or easily fatigued plastic snap-fit ​​mechanism.

[0030] In one embodiment of this application, see reference Figure 5 and Figure 6 As shown, magnetic strips 7 are respectively provided on the side wall of the bottom opening of the protective box 6 and the insertion end of the sliding cover 61.

[0031] In the above embodiment, when the sliding cover 61 is closed, the magnetic strips at both ends attract each other, generating an additional holding force to prevent the sliding cover 61 from accidentally sliding open due to daily shaking, vibration or other unexpected situations, causing the walkie-talkie inside the protective box 6 to fall out.

[0032] In one embodiment of this application, the outer walls of the first connecting rope 4 and the second connecting rope 5 are covered with a nylon layer.

[0033] In the above embodiments, the underground mining environment is complex, and the connecting rope is prone to friction with rocks, equipment edges, etc. The nylon layer can effectively resist wear and tear, prevent premature exposure and breakage of the rope core, and greatly improve the overall durability and reliability of the connecting rope.

[0034] In actual use, in the initial (locked) state, the spring force of spring 22 drives the pin 21 into the slot 23, causing the annular fastener 1 to form a closed loop, thus securely attaching to a belt, backpack strap, or designated hanging point. When installation or removal is required, simply push the lever 211 manually to overcome the force of spring 22 and disengage the pin 21 from the slot 23. At this point, the notch on the fastener 1 opens, allowing for easy attachment or removal. Releasing the lever 211 causes spring 22 to push the pin 21 back into the slot 23, automatically resetting and locking the notch closure mechanism of the fastener 1.

[0035] The magnetic clasp offers two key operating modes. In normal mode, the strong magnetic force ensures a secure connection between the two connecting ropes, allowing for normal suspension of the walkie-talkie. In emergency mode, if the walkie-talkie or protective box 6 is jammed by external force, the worker only needs to apply a pulling force exceeding the preset magnetic force (usually much less than the force that would cause injury). The optional magnetic clasp (3kg pulling force required for release) will quickly separate, disconnecting the connection and freeing the worker from restraint, thus preventing accidents.

[0036] The protective box 6 encloses the walkie-talkie, isolating it from harsh external environments (collisions). This not only prevents wear and tear on the walkie-talkie's casing and extends the device's lifespan, but also provides some cushioning, reducing impact damage in the event of an accidental drop.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
