Description

Technical Field

[0001] This utility model relates to the field of electronic communication equipment technology, specifically to an electronic communication device for power engineering. Background Technology

[0002] In power engineering maintenance, multiple workers need to work simultaneously and communicate in real time during the work process. This communication is usually done through walkie-talkies, and most existing walkie-talkies are handheld.

[0003] According to a public notice (Announcement No.: CN222321530U) regarding a multifunctional electronic communication device for power engineering, the above application aims to prevent the walkie-talkie from falling to the ground when held in hand. By setting a snap-fit ​​component, the walkie-talkie can be snapped into a clothing pocket, thus freeing up the hands of power engineering maintenance personnel for maintenance operations. At the same time, the snap-fit ​​component can lock and unlock the connection between the anti-drop component and the main body of the casing, facilitating the disassembly and assembly of the anti-drop component and effectively improving the ease of use of the device.

[0004] However, in actual use, the above-mentioned devices generally use elastic ropes or coil springs to connect the worker's arm and the communication device. However, such connection methods cause the communication device to come into contact with the worker's arm quickly once it is released from the hand, and the impact force may cause injury to the worker's arm. In view of this, we propose an electronic communication device for power engineering. Utility Model Content

[0005] The purpose of this utility model is to provide an electronic communication device for power engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electronic communication device for power engineering, comprising a body, an elastic card plate fixedly installed on the side of the body, a take-up roller rotatably installed on the bottom inner wall of the body, a pull rope wound around the arc-shaped outer wall of the take-up roller, an elastic ring fixedly connected to the end of the pull rope away from the take-up roller, and a take-up assembly provided inside the body;

[0007] The winding assembly includes a push plate, which is slidably mounted on the inner wall of the machine body. A push rod is fixedly connected to the outer wall of the push plate on the side away from the elastic clamping plate. A diagonal rod is hinged to the end of the push rod away from the push plate, and a ratchet wheel is hinged to the end of the diagonal rod away from the push rod. A ratchet wheel is coaxially fixedly mounted on the winding roller. A coil spring is sleeved on the arc-shaped outer wall of the end of the winding roller. A slide rod is fixedly mounted on the inner wall of the machine body, and a return spring is sleeved on the outer wall of the slide rod.

[0008] Preferably, the surface shell of the machine body near the bottom end of the elastic plate is provided with an installation cavity, and a flexible rubber panel is fixedly connected to the inner surface of the installation cavity, so that when the elastic plate is subjected to external pressure and moves toward the machine body, the bottom end of the elastic plate will squeeze the flexible rubber panel to cause it to deform to a certain extent.

[0009] Preferably, the machine body is provided with a limiting slide rail inside, and the surface of the limiting slide rail near the ratchet wheel is provided with a T-shaped groove. At the same time, T-shaped blocks that are adapted to the T-shaped groove are fixedly installed on the upper and lower outer surfaces of the ratchet wheel, so that the ratchet wheel can only slide in the horizontal direction inside the machine body.

[0010] Preferably, the inner wall of the ratchet wheel is provided with a through hole that matches the slide bar, and the slide bar is disposed inside the through hole. The two ends of the return spring are fixedly connected to the outer wall of the ratchet wheel and the inner wall of the machine body, respectively, so that after the pushing force applied by the external elastic plate ends, the ratchet wheel can return to its original position due to the elastic force of the return spring.

[0011] Preferably, the machine body is provided with a clamping assembly, which includes a small gear. The small gear is coaxially fixedly installed with the take-up roller. A lead screw is rotatably installed on the inner wall of the machine body. A large gear is fixedly installed through the arc-shaped outer wall of the lead screw. A lead screw slider is slidably connected to the outer wall of the lead screw. A guide rod is fixedly installed on the inner wall of the machine body. A locking block is slidably installed on the inner wall of the lead screw slider.

[0012] Preferably, the guide rod includes a large-diameter end and a small-diameter end. The large-diameter end of the guide rod is located on the side away from the winding roller and the end of the pull rope, and the large-diameter end and the small-diameter end of the guide rod are set with an inclined arc surface to avoid interference with the movement of the lead screw slider.

[0013] Preferably, the inner wall of the lead screw slider has a transmission hole with a diameter larger than the outer diameter of the guide rod, and the locking block is slidably installed at the top center of the transmission hole.

[0014] Compared with the prior art, this utility model provides an electronic communication device for power engineering, which has the following beneficial effects:

[0015] 1. This electronic communication equipment for power engineering is equipped with a clamping assembly. In the event of the equipment slipping and falling during power engineering operations, the bottom end of the elastic clamping plate will push towards one side of the machine body. Combined with the deformability of the flexible rubber panel in contact with the bottom end of the elastic clamping plate, the push plate, along with the push rod and the diagonal rod, can drive the ratchet wheel to release the unidirectional rotation limit of the ratchet wheel. At this time, under the elastic force of the coil spring, the pull rope will be wound on the take-up roller to cause the machine body to move quickly and approach the worker's arm. After the pushing force applied by the external elastic clamping plate ends, the elastic force of the return spring allows the ratchet wheel to return to its original position, restoring the unidirectional rotation limit of the ratchet wheel and preventing the machine body from causing excessive impact to the worker and thus causing injury to the worker's body.

[0016] 2. This electronic communication equipment for power engineering is equipped with a clamping component. When the lead screw slider is affected by the rotation of the lead screw and moves continuously toward the side away from the end of the pull rope and the connection point of the take-up roller, the inclined arc surface on the outer wall of the guide rod will gradually exert an upward squeezing force on the clamping block. This causes the top of the clamping block to extend into the inclined circular hole, thereby increasing the squeezing and friction on the surface of the pull rope. Ultimately, this causes the pull rope to decelerate, preventing impact injury to the user's arm when the machine quickly retracts the line after a fall, thus ensuring the safety of the device.

Detailed Implementation

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: an electronic communication device for power engineering, including a body 1, an elastic clamping plate 2 fixedly installed on the side of the body 1, a take-up roller 3 rotatably installed on the bottom inner wall of the body 1, a pull rope 4 wound around the arc-shaped outer wall of the take-up roller 3, an elastic ring 5 fixedly connected to the end of the pull rope 4 away from the take-up roller 3, and a take-up assembly 6 provided inside the body 1, the take-up assembly 6 including a push plate 61, a push rod 62, a diagonal rod 63, a ratchet wheel 64, a ratchet wheel 65, a coil spring 66, a slide rod 67, and a return spring 68.

[0025] In one embodiment of this utility model, a push plate 61 is slidably mounted on the inner wall of the machine body 1. A push rod 62 is fixedly connected to the outer wall of the push plate 61 away from the elastic clamping plate 2. A diagonal rod 63 is hinged to the end of the push rod 62 away from the push plate 61. A ratchet wheel 64 is hinged to the end of the diagonal rod 63 away from the push rod 62. A ratchet wheel 65 is coaxially fixedly mounted on the take-up roller 3. A coil spring 66 is sleeved on the arc-shaped outer wall of the end of the take-up roller 3. A slide rod 67 is fixedly mounted on the inner wall of the machine body 1. A return spring 68 is sleeved on the outer wall of the slide rod 67.

[0026] Furthermore, an arc-shaped protrusion is provided at the center of the elastic clamp 2 near the side of the machine body 1, allowing the operator to fix the machine body 1 to clothing or a belt for temporary access, thus improving the ease of use of the device. Simultaneously, a mounting cavity is provided on the surface shell of the machine body 1 near the bottom of the elastic clamp 2, and a flexible rubber panel is fixedly connected to the inner surface of this mounting cavity. This allows the bottom surface of the elastic clamp 2 to compress the flexible rubber panel when it is subjected to external pressure and moves towards the machine body 1, causing it to deform. Specifically, the push plate 61 and the aforementioned flexible rubber panel are positioned on the same horizontal line. When the flexible rubber panel deforms, it will exert a pushing force on the push plate 61 toward the center of the body 1. In addition, the elastic ring 5 is made of elastic fabric so that the operator can wear it on their wrist by flipping and inserting it to ensure that the body 1 will not fall off the operator's arm. Furthermore, the body 1 has built-in electrical communication components, and the front of the body 1 is also equipped with a keyboard, display screen, buttons, earpiece, and microphone to facilitate remote communication by the operator.

[0027] In addition, there are two sets of push rods 62, inclined rods 63, pawl wheels 64, ratchet wheels 65, coil springs 66, slide rods 67, and return springs 68. The two sets of push rods 62, inclined rods 63, pawl wheels 64, ratchet wheels 65, coil springs 66, slide rods 67, and return springs 68 are symmetrically arranged with the vertical central axis of the take-up roller 3 as the axis of symmetry. Furthermore, the machine body 1 is provided with a limit slide rail inside, and a T-shaped groove is opened on the surface of the limit slide rail near the pawl wheel 64. At the same time, T-shaped blocks that are adapted to the T-shaped groove are fixedly installed on the upper and lower outer surfaces of the pawl wheel 64. This design ensures that the ratchet wheel 64 can only slide horizontally inside the machine body 1 without rotating. Specifically, the ratchet wheel 65 is the same size as the ratchet wheel 64, and the side of the ratchet wheel 64 is hinged to the diagonal bar 63. When the push plate 61 exerts a pushing force on the push rod 62, the diagonal bar 63, in conjunction with the T-block and T-slot, pushes the ratchet wheel 64 to release the unidirectional rotation limit on the ratchet wheel 65 outside the take-up roller 3. In the initial state, due to the limitation of the ratchet wheel 64, the ratchet wheel 65 and the take-up roller 3 can only perform the unwinding action on the pull rope 4.

[0028] Specifically, the two ends of the coil spring 66 are fixedly connected to the inner wall of the machine body 1 and the arc-shaped outer wall surface of the take-up roller 3, respectively, so that the take-up roller 3 always has a tendency to rotate in the opposite direction to achieve reset when rotating. At the same time, the inner wall of the ratchet wheel 64 is provided with a through hole that matches the slide rod 67, and the slide rod 67 is located inside the through hole. The two ends of the reset spring 68 are fixedly connected to the outer wall of the ratchet wheel 64 and the inner wall of the machine body 1, respectively, so that after the pushing force applied by the external elastic plate 2 ends, the ratchet wheel 64 can return to its original position due to the elastic force of the reset spring 68, and the unidirectional rotation limit of the ratchet wheel 65 is realized again.

[0029] Please refer to the attached instruction manual. Figure 3 and Figure 6 The machine body 1 is equipped with a clamping assembly 7, which includes a small gear 71. The small gear 71 is coaxially fixedly installed with the take-up roller 3. A lead screw 72 is rotatably installed on the inner wall of the machine body 1. A large gear 73 is fixedly installed through the arc-shaped outer wall of the lead screw 72. A lead screw slider 74 is slidably connected to the outer wall of the lead screw 72. A guide rod 75 is fixedly installed on the inner wall of the machine body 1. A locking block 76 is slidably installed on the inner wall of the lead screw slider 74.

[0030] In this embodiment of the invention, the large gear 73 and the small gear 71 mesh to achieve transmission, and the top surface of the lead screw slider 74 is slidably connected to the inner wall of the machine body 1, thereby guiding and restricting the movement of the lead screw slider 74. Specifically, an inclined circular hole is provided on the bottom inner wall of the lead screw slider 74, and the inner diameter of the inclined circular hole is larger than the outer diameter of the pull rope 4, so that the pull rope 4 can pass through the inclined circular hole to move, thereby cooperating with the take-up roller 3 to realize the winding and unwinding of the pull rope 4. Furthermore, the guide rod 75 includes a large diameter end and a small diameter end. The large diameter end of the guide rod 75 is located on the side away from the take-up roller 3 and the end of the pull rope 4, and the large diameter end and the small diameter end of the guide rod 75 are set with an inclined arc surface to avoid interference with the movement of the lead screw slider 74.

[0031] Meanwhile, a transmission hole with a diameter larger than the outer diameter of the guide rod 75 is opened on the inner wall of the lead screw slider 74, and the locking block 76 is slidably installed at the top center of the transmission hole. When the lead screw slider 74 is affected by the rotation of the lead screw 72 and moves continuously toward the side away from the end of the pull rope 4 and the connection point of the take-up roller 3, the inclined arc surface on the arc-shaped outer wall of the guide rod 75 will gradually exert an upward squeezing force on the locking block 76, thereby causing the top of the locking block 76 to extend into the inclined circular hole, thereby increasing the squeezing and friction on the surface of the pull rope 4, and ultimately causing the pull rope 4 to decelerate, so as to avoid the impact injury to the user's arm when the machine body 1 quickly retracts the line to the user's arm after falling, thus affecting the safety of the device.

[0032] In this invention, during use, the operator wears the device on their wrist by flipping and inserting it to ensure that the device 1 will not fall off their arm. During use, the ratchet 65 and pawl 64 allow the pull rope 4 to be released to a comfortable length for the user, enabling remote communication via buttons on the device 1 and its built-in electrical communication components. However, in the event of the device slipping and falling during electrical engineering work, due to the limited length of the pull rope 4, the device 1 will fall in an arc, colliding with the operator or other objects. This causes the bottom of the elastic locking plate 2 to push towards one side of the device 1, coordinating with... The deformability of the flexible rubber panel in contact with the bottom of the elastic plate 2 generates a pushing force on the push plate 61 toward the center of the machine body 1. This, in conjunction with the push rod 62 and the inclined rod 63, pushes the ratchet wheel 64 to release the unidirectional rotation limit of the ratchet wheel 65 outside the take-up roller 3. At this time, under the elastic force of the coil spring 66, the pull rope 4 will be wound on the take-up roller 3 to cause the machine body 1 to move quickly and approach the worker's arm. After the pushing force applied by the external elastic plate 2 ends, the ratchet wheel 64 can return to its original position due to the elastic force of the return spring 68, and the unidirectional rotation limit of the ratchet wheel 65 is restored again, thus avoiding excessive impact on the worker from the machine body 1 and causing injury to the worker.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
