Abstract
Description
Technical Field
[0001] This application relates to the field of remote control technology, and more particularly to an intrinsically safe remote control for mining applications. Background Technology
[0002] In environments such as mines where explosive gases are present, electronic devices used must meet intrinsic safety requirements, meaning that the device cannot generate enough energy to ignite the surrounding explosive mixture under normal operating conditions and fault conditions. Traditional remote controls often cannot meet this stringent requirement. Furthermore, due to the special nature of the mining working environment, workers often need to squat or bend over, which makes it easy for remote controls placed in their work clothes pockets to fall out and be damaged. Utility Model Content
[0003] The problem this application aims to solve is that existing workers often need to squat or bend over, causing remote controls placed in their work uniform pockets to easily fall out and become damaged.
[0004] To solve the above-mentioned technical problems, this application provides an intrinsically safe remote controller for mining, including a remote controller body and a base for accommodating and supporting the body. A strap is arranged on the outside of the base and connected to it to fix the body inside. A buckle plate is arranged on the center line of the back of the base and hinged thereto for hanging it on a belt. A clip is also arranged on the top of the body to form a full enclosure, with one end connected to the base. The other end of the clip is engaged with the strap.
[0005] Because the remote control of this application is designed with a base, strap, buckle plate and clip, it not only meets intrinsic safety requirements, but also has good fixing performance, effectively preventing the remote control from being accidentally dropped during use. This solves the problem in the prior art where workers often need to squat or bend over, causing the remote control placed in their work clothes pocket to easily fall out and be damaged.

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Example
[0012] This application relates to an intrinsically safe remote controller for mining applications, such as... Figure 1-4 As shown, the remote control includes a remote control body 1 and a base 2 for supporting and positioning the body 1. The body 1 limits the energy in the electrical circuit to ensure that no electric sparks or thermal effects sufficient to ignite an explosive mixture are generated under normal and accident conditions. The body 1 adopts a low-energy circuit design, and all components are selected to meet intrinsic safety requirements. The exterior of the body 1 is made of explosion-proof and dustproof materials to enhance its durability in harsh mining environments. The base 2 has a semi-enclosed structure that can closely fit the shape of the remote control body 1 and provide good support. A strap 3 is arranged on the exterior of the base 2 to connect to it. The design of the strap 3 allows the remote control to be firmly fixed inside the base 2. The strap 3 has a T-shaped structure with three ends. This design allows the strap 3 to be constrained and fixed from both sides and the bottom of the body 1 at the same time. The ends are connected to the base 2 by rivets or screws. The connection method is firm and reliable and not easy to loosen. The strap 3 is made of high-strength and wear-resistant materials to ensure that it will not break or be damaged during long-term use.
[0013] By limiting the energy in the electrical circuit and selecting components that meet intrinsic safety requirements, the safety of the remote control is ensured when used in explosive environments such as mines. The design of the base 2 and strap 3 allows the remote control to be firmly fixed inside the base 2, effectively preventing it from falling and breaking when squatting, bending over, or performing other actions. The exterior of the body 1 is made of explosion-proof and dustproof materials, and the base 2 and strap 3 are made of high-strength and wear-resistant materials, giving the remote control a long service life in harsh mining environments.
[0014] To further enhance the constraint and fixation effect of the device 1 on the base 2, this application also cleverly arranges a cassette 4 on the top of the device 1. The design of this cassette 4 not only increases the stability of the remote control, but also takes into account the ease of use. One end of the cassette 4 is firmly connected to the back of the base 2, ensuring that it becomes an integral part of the base 2 and is not easy to fall off. The other end of the cassette 4 is connected to the intersection of the T-shaped structure of the strap 3. This design allows the cassette 4, the strap 3 and the base 2 to form a stable, fully enclosed structure, which greatly enhances the fixation effect of the device 1.
[0015] To facilitate the handling of the device 1, a stepped buckle 5 protruding outward is specially designed at the intersection. This buckle 5 is designed to be easy for fingers to grip and provides a firm fixing point when the tape 4 is tightened. The upper part of the tape 4 forms an oval-shaped groove 6, which consists of a large hole and a small hole. The design of the large hole allows the buckle 5 to be easily inserted when the tape 4 is pulled, while the small hole is used to fit tightly with the buckle 5 after the tape 4 is released, ensuring that the device 1 will not be easily loosened by external force. In order to meet the requirement that the tape 4 can automatically retract and tightly fix the device 1 after being pulled, the tape 4 is made of elastic materials such as rubber or spandex. These materials not only have good elasticity, but also maintain stable performance during long-term use and are not easy to age or deform.
[0016] When it is necessary to fix the device 1 to the base 2, simply pull the cartridge 4 so that the buckle 5 passes through the large hole, and then release the cartridge 4. Under the tension of the cartridge 4 itself, the small hole will fit tightly with the buckle 5, thus firmly fixing the device 1 to the base 2. When it is necessary to remove the device 1, simply pull the cartridge 4 again so that the buckle 5 moves from the small hole to the punched hole and then comes out of the large hole, and the device 1 can be easily removed. The design of the cartridge 4 further enhances the fixing effect of the device 1 on the base 2. Even in the environment of violent movement or vibration, the remote control can remain stable and not fall off. The stepped buckle 5 and the oval slot 6 make it very convenient and quick to take off and put away the device 1, greatly improving the ease of use. The choice of elastic materials such as rubber or spandex ensures the stability and durability of the cartridge 4 during long-term use, and it is not easy to be damaged or fail.
[0017] To facilitate carrying the device 1 with the base 2, this application includes a vertically arranged buckle plate 7 hinged to the center line of the back of the base 2. This buckle plate 7 design allows the base 2 to be easily attached to the upper part of the belt, greatly improving the portability of the remote control. The buckle plate 7 is connected to the center line of the back of the base 2 via a hinge, allowing it to rotate freely within a certain range to adapt to different belt widths and wearing angles. The hinge design ensures the stability of the buckle plate 7 during rotation, preventing it from easily loosening or falling off due to external forces. To enhance the connection stability between the base 2 and the belt, a torsion spring 8 is arranged at the hinge position between the buckle plate 7 and the base 2. The function of the torsion spring 8 is to provide restoring force after the buckle plate 7 rotates, so that the buckle plate 7 can fit tightly on the waist belt and is not easy to shake or fall off. The selection and design of the torsion spring 8 takes into account its elasticity and durability, ensuring that it can maintain stable performance during long-term use and is not easy to age or fail. One end of the buckle plate 7 also has an inwardly bent hook 9. The design of this hook 9 is to further enhance the anti-slip ability between the base 2 and the waist belt. When the buckle plate 7 is attached to the waist belt, the hook 9 will hook the waist belt tightly to prevent the base 2 from sliding up or down due to external force. Even when performing strenuous exercise or bending over, the remote control can remain stably attached to the waist belt and is not easy to fall off.
[0018] When the remote control needs to be carried, simply open the buckle 7, hang the base 2 on the belt, and then adjust the angle and position of the buckle 7 so that the hook 9 tightly hooks the belt. When the remote control needs to be removed, simply press one end of the buckle 7 gently to release the hook 9 from the belt, and the base 2 and the main body 1 can be easily removed. Alternatively, open the belt 4 and take out the main body 1 from inside the base 2. The design of the buckle 7 allows the base 2 to be easily hung on the belt, greatly improving the portability of the remote control and making it convenient for staff to operate it anytime and anywhere. The torsion spring 8 and the hook 9 enhance the connection stability between the base 2 and the belt, preventing the remote control from shaking or falling off due to external force during use. The design of the hook 9 effectively improves the anti-slip ability between the base 2 and the belt, so that the remote control can remain stably hung on the belt even when performing strenuous exercise or bending over.
[0019] To further enhance the anti-slip performance of the base 2, this application cleverly creates a straight slot 10 on the surface of the buckle plate 7 and arranges an outwardly protruding protrusion 11 on the back of the base 2. This design allows the protrusion 11 to penetrate deep into the slot 10, thereby further applying limiting constraints and ensuring the stability of the base 2 during wear. The straight slot 10 design on the surface of the buckle plate 7 provides a space for the protrusion 11 to be inserted. The length and width of the slot 10 have been carefully calculated to ensure that the protrusion 11 can be smoothly inserted and tightly fitted. The protrusion 11 on the back of the base 2 matches the shape and size of the slot 10 and can be firmly inserted into the slot 10 to form an effective limiting constraint.
[0020] When the buckle 7 is attached to the belt, the protrusion 11 inserts into the slot 10, restricting the horizontal movement of the buckle 7 relative to the base 2. Even under external force, the buckle 7 is not easily detached or slipped from the base 2. The cooperation between the protrusion 11 and the slot 10 also enhances the vertical stability of the base 2. When the operator bends over or squats, the interaction force between the protrusion 11 and the slot 10 keeps the base 2 stable, preventing it from falling due to gravity. The design of the protrusion 11 and the slot 10 does not affect the normal opening and closing of the buckle 7. When wearing or removing the remote control, the operator only needs to follow the normal operation without extra effort. The fit between the protrusion 11 and the slot 10 is tight but not prone to jamming. Even after long-term wear, it will not become difficult to remove or be damaged due to friction or wear. When wearing the remote control, ensure that the slot 10 of the buckle 7 is aligned with the base 2. Align the protrusions 11, then gently press down on the buckle 7 to allow the protrusions 11 to smoothly insert into the slot 10. Adjust the angle and position of the buckle 7 to ensure it fits snugly on the belt, guaranteeing the remote control is stable and does not wobble. To remove the remote control, simply press down on one end of the buckle 7 to dislodge the protrusions 11 from the slot 10, allowing easy removal of the base 2 and body 1. The design of the protrusions 11 and slot 10 further enhances the anti-slip performance of the base 2. Even during vigorous exercise or complex movements, the remote control remains stably attached to the belt and is not prone to falling off. The limiting and restraining effect of the protrusions 11 and slot 10 enhances the stability of the base 2 during wear. Regardless of the user's posture or state, the remote control remains stable and does not wobble. The design of the protrusions 11 and slot 10 does not affect the normal opening and closing of the buckle 7, maintaining the ease of use of the remote control.
[0021] To prevent reduced heat dissipation when the remote control is placed inside the base 2, this application provides ventilation holes 12 evenly distributed on the surface of the base 2. This design ensures that the back of the device 1 is not obstructed by the base 2, thus maintaining the normal operating temperature and performance of the remote control. The ventilation holes 12 are evenly distributed on the surface of the base 2, especially in the area in contact with the back of the device 1. These ventilation holes 12 can be circular, elliptical, or other suitable shapes to ensure smooth airflow. The size and number of the ventilation holes 12 are carefully calculated to ensure sufficient ventilation without affecting the structural strength and stability of the base 2. When the remote control is placed inside the base 2, the heat generated on the back of the device 1 can be dissipated to the external environment through the ventilation holes 12. Thus, even after prolonged use, the device 1 will not suffer from overheating, affecting its performance and lifespan. The design of the ventilation holes 12 also considers dustproof and waterproof requirements. Through reasonable hole diameter and layout, while ensuring ventilation, dust and moisture can be effectively prevented from entering the interior of the base 2, protecting the electronic components of the remote control from damage.
[0022] The ventilation hole 12 ensures good heat dissipation when the remote control is placed inside the base 2, preventing performance degradation or malfunction due to overheating. The hole 12 also makes the remote control more comfortable to use, preventing discomfort caused by overheating and improving work efficiency and user experience. When placing the remote control inside the base 2, ensure the hole 12 is not obstructed or blocked. If necessary, regularly clean the dust and debris around the hole 12 to keep it unobstructed. The ventilation hole 12 effectively improves the remote control's heat dissipation performance, preventing performance degradation or malfunction due to overheating. Good heat dissipation allows the remote control's electronic components to operate at lower temperatures, extending their lifespan and reliability. The remote control does not cause discomfort due to overheating during use, improving work efficiency and user experience.
[0023] When using, correctly place the remote control body 1 into the base 2, ensuring good contact between the body 1 and the base 2 to avoid loosening or shaking. If there are ventilation holes 12 on the surface of the base 2, ensure that these holes 12 are not blocked or obstructed to maintain good heat dissipation for the remote control. Open the buckle 7 on the back of the base 2 and hang the base 2 on the belt at a suitable position. Adjust the angle and position of the buckle 7 so that the hook 9 is firmly hooked on the belt, ensuring that the remote control is stable and does not shake. If you need to adjust the wearing angle or position of the remote control, you can gently press one end of the buckle 7 to release the hook 9 from the belt, and then reattach and adjust.
