Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, and more specifically, to a tool for disassembling and assembling a water meter glass cover. Background Technology

[0002] A water meter is a measuring instrument used to measure and record the flow rate of tap water (or other liquids) in pipes. It is widely used in homes, businesses, and industrial sites, and is a core device for water supply companies to settle water consumption accounts with users. Water meters are used to record water consumption. However, during routine maintenance and flow management, it is generally necessary to remove the glass cover of the water meter for operation. During the removal of the water meter glass, uneven force applied by the disassembly tool may cause the water meter glass to break. Therefore, we provide a tool for disassembling and assembling the water meter glass cover. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a tool for disassembling and assembling water meter glass covers, which has the advantage of disassembling and assembling water meter glass with uniform force.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tool for disassembling and assembling a water meter glass cover, comprising a protective housing, wherein a clamping mechanism is provided inside the protective housing, and a protective mechanism is provided on the outer wall of the clamping mechanism; The clamping mechanism includes a fixed block, a cross support frame fixedly connected to the outer wall of the fixed block, a connecting rod rotatably connected to the inner wall of the fixed block, a button fixedly connected to the top of the connecting rod, a bevel gear I fixedly connected to the end of the connecting rod away from the button, a worm gear rotatably connected to the inner wall of the fixed block, a bevel gear II fixedly connected to the outer wall of the worm gear, several fixed rods I rotatably connected to the inner wall of the cross support frame, a push rod fixedly connected to the outer wall of each fixed rod I, a moving block rotatably connected to the outer wall of the push rod, a worm wheel fixedly connected to the outer surface of each fixed rod I, a fixed rod II rotatably fixedly connected to the cross support frame, and an auxiliary connecting rod fixedly connected to the outer surface of each fixed rod II.

[0005] As a preferred embodiment of this utility model, a telescopic rod is fixedly connected to the outer wall of the movable block, a clamping block is fixedly connected to the end of the telescopic rod away from the movable block, and a spring is fixedly connected to the outer wall of the clamping block.

[0006] As a preferred embodiment of this utility model, the outer surface of the first bevel gear is meshed with the outer surface of the second bevel gear, and the outer surface of the first fixed rod is meshed with the outer surface of the worm gear.

[0007] As a preferred embodiment of this utility model, the number of worm gears is several, and the end of the spring away from the clamping block is fixedly connected to the outer wall of the spring.

[0008] As a preferred embodiment of this utility model, the protective mechanism includes a slider, a fixing plate 1 fixedly connected to the outer wall of the slider, a central rod in contact with the outer wall of the slider, a pressing block fixedly connected to the end of the central rod away from the slider, a semi-circular locking block fixedly connected to the outer wall of the fixing plate 1, a fixing plate 2 fixedly connected to the inner wall of the protective shell, a rotating rod fixedly connected to the inner wall of the fixing plate 2, a concave clamping block rotatably connected to the outer surface of the rotating rod, a convex clamping block rotatably connected to the outer surface of the rotating rod, an extension plate fixedly connected to the outer surface of the slider, and a spring 2 fixedly connected to the outer wall of the extension plate.

[0009] In a preferred embodiment of this invention, the outer wall of the slider is fixedly connected to the outer wall of the fixed block, and the outer surface of the central rod is slidably connected to the inner wall of the protective housing.

[0010] As a preferred technical solution of this utility model, the end of the second spring away from the extension plate is fixedly connected to the outer wall of the second fixed plate, and the outer surface of the concave clamping block is in contact with the outer surface of the semi-circular locking block.

[0011] In a preferred embodiment of this utility model, the outer surface of the convex clamping block is in contact with the outer surface of the semi-circular locking block, and the number of springs is several.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a clamping mechanism. A rotating button drives the connecting rod to rotate. When the connecting rod rotates, bevel gear one also rotates, and bevel gear two rotates as well. When bevel gear two rotates, the worm rotates inside the fixed block. Because the worm meshes with four worm wheels, when the worm rotates, the four worm wheels also rotate, and fixed rod one rotates simultaneously. When fixed rod one rotates, the push rod rotates, causing the moving block to move. Simultaneously, the auxiliary connecting rod limits the angle of the moving block during movement. When the clamping block contacts the water meter glass, it pushes the telescopic rod to retract, and spring one is compressed. When the telescopic rod retracts to its final position, the four clamping blocks firmly clamp the water meter glass, thus facilitating its installation and removal. Its advantages include clamping and fixing the water meter glass that needs to be installed and removed, improving safety and stability during operation, and increasing operational efficiency.

[0013] 2. This utility model uses a protective mechanism to insert the slider into the protective housing. When the slider contacts the central rod, it pushes the central rod to move. When the slider moves, the fixing plate also moves, and the semi-circular locking block also moves. When the semi-circular locking block moves to a suitable distance, the protruding part of the semi-circular locking block pushes the convex and concave clamping blocks to rotate outward on the rotating rod surface. At the same time, the two springs also compress. When the semi-circular locking block is inserted into the concave and convex clamping blocks, the springs push the extension plate to move, thereby pushing the convex and concave clamping blocks closer to each other, thus fixing the device inside the protective housing. When the device needs to be used, the slider can be pushed out by pushing the pressing block. Its advantage is that it protects the device when it is not in use, preventing the device from being damaged by bumps. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6 As shown, this utility model provides a tool for disassembling and assembling a water meter glass cover, including a protective housing 11, a clamping mechanism 1 inside the protective housing 11, and a protective mechanism 2 on the outer wall of the clamping mechanism 1. The clamping mechanism 1 includes a fixed block 101, a cross support frame 102 fixedly connected to the outer wall of the fixed block 101, a connecting rod 104 rotatably connected to the inner wall of the fixed block 101, a button block 103 fixedly connected to the top of the connecting rod 104, a bevel gear 105 fixedly connected to the end of the connecting rod 104 away from the button block 103, a worm gear 107 rotatably connected to the inner wall of the fixed block 101, a bevel gear 106 fixedly connected to the outer wall of the worm gear 107, several fixed rods 108 rotatably connected to the inner wall of the cross support frame 102, a push rod 109 fixedly connected to the outer wall of the fixed rods 108, a moving block 111 rotatably connected to the outer wall of the push rods 109, a worm wheel 110 fixedly connected to the outer surface of the fixed rods 108, a fixed rod 112 rotatably fixedly connected to the cross support frame 102, and an auxiliary connecting rod 113 fixedly connected to the outer surface of the fixed rod 112.

[0018] Rotating the button 103 drives the connecting rod 104 to rotate. When the connecting rod 104 rotates, the first bevel gear 105 also rotates. At this time, the second bevel gear 106, which meshes with the first bevel gear 105, will rotate. When the second bevel gear 106 rotates, the worm 107 rotates inside the fixed block 101. Since the worm 107 meshes with the four worm wheels 110, when the worm 107 rotates, the four worm wheels 110 will also rotate. At this time, the first fixed rod 108 will also rotate simultaneously. When the first fixed rod 108 rotates, the push rod 109 will rotate. At this time, the moving block 111 will move. At the same time, the auxiliary connecting rod 113 will limit the angle of the moving block 111 during movement, so that it can always maintain parallel movement.

[0019] The movable block 111 is fixedly connected to the outer wall of the telescopic rod 114, and the end of the telescopic rod 114 away from the movable block 111 is fixedly connected to the clamping block 116. The clamping block 116 is fixedly connected to the outer wall of the spring 115.

[0020] The outer surface of bevel gear 105 meshes with the outer surface of bevel gear 2 106, and the outer surface of fixed rod 108 meshes with the outer surface of worm gear 110.

[0021] There are several worm gears 110, and the end of spring 115 away from the clamping block 116 is fixedly connected to the outer wall of spring 115.

[0022] When the clamping block 116 contacts the water meter glass, it pushes the telescopic rod 114 to retract, and at the same time the spring 115 is also compressed. When the telescopic rod 114 is retracted to its end, the four clamping blocks 116 will firmly clamp the water meter glass, thereby clamping and fixing the water meter glass that needs to be installed and removed, improving the safety and stability during operation, and also improving the efficiency of operation.

[0023] The protective mechanism 2 includes a slider 201, a fixing plate 204 fixedly connected to the outer wall of the slider 201, a central rod 202 in contact with the outer wall of the slider 201, a pressing block 203 fixedly connected to the end of the central rod 202 away from the slider 201, a semi-circular locking block 205 fixedly connected to the outer wall of the fixing plate 204, a fixing plate 206 fixedly connected to the inner wall of the protective housing 11, a rotating rod 208 fixedly connected to the inner wall of the fixing plate 206, a concave clamping block 209 rotatably connected to the outer surface of the rotating rod 208, a convex clamping block 210 rotatably connected to the outer surface of the rotating rod 208, an extension plate 211 fixedly connected to the outer surface of the slider 201, and a spring 207 fixedly connected to the outer wall of the extension plate 211.

[0024] By inserting the slider 201 into the protective housing 11, when the slider 201 contacts the central rod 202, it will push the central rod 202 to move. When the slider 201 moves, the fixing plate 204 will also move. At this time, the semi-circular locking block 205 will also move. When the semi-circular locking block 205 moves to a suitable distance, the protruding part of the semi-circular locking block 205 will push the convex clamping block 210 and the concave clamping block 209 to rotate outward on the surface of the rotating rod 208. At the same time, the two springs 207 will also be compressed. When the semi-circular locking block 205 is inserted into the concave clamping block 209 and the convex clamping block 210, the springs 207 will push the extension plate 211 to move, thereby pushing the convex clamping block 210 and the concave clamping block 209 closer to each other, thus fixing the device inside the protective housing 11. When the device needs to be used, the slider 201 can be pushed out by pushing the pressing block 203.

[0025] The outer wall of the slider 201 is fixedly connected to the outer wall of the fixed block 101, and the outer surface of the central rod 202 is slidably connected to the inner wall of the protective shell 11.

[0026] The end of spring 207 away from extension plate 211 is fixedly connected to the outer wall of fixed plate 206, and the outer surface of concave clamp 209 is in contact with the outer surface of semi-circular lock block 205.

[0027] The outer surface of the convex clamping block 210 is in contact with the outer surface of the semi-circular locking block 205, and there are several springs 207.

[0028] The slider 201 slides inside the protective housing 11, thereby restricting the position of the device. The protective housing 11 surrounds the device, which can store and protect it, preventing damage to the internal components of the device due to bumps when the device is not in use, thus affecting the efficiency of the device.

[0029] Working principle and usage process of this utility model: When workers disassemble and install the water meter glass, rotating the button 103 causes the connecting rod 104 fixed at its bottom to rotate. When the connecting rod 104 rotates, the bevel gear 105 fixed at its bottom also rotates. At this time, the bevel gear 106 meshing with the bevel gear 105 will rotate. When the bevel gear 106 rotates, the worm 107 fixed on the outer wall of the bevel gear 106 rotates inside the fixing block 101. Because the worm 107 meshes with the four worm wheels 110 on its outer surface, when the worm 107 rotates, the four worm wheels 110 on its outer surface will also rotate. The fixing rod 108, fixed to the inner wall of the meter, will also rotate simultaneously. When the fixing rod 108 rotates, the push rod 109, fixed to its outer surface, will rotate. At this time, the moving block 111, which rotates at the other end of the push rod 109, will move. Simultaneously, the auxiliary connecting rod 113, which rotates inside the moving block 111, will limit the angle of the moving block 111 during movement, ensuring that it always moves in parallel. When the clamping block 116 contacts the water meter glass, it will push the telescopic rod 114 to retract, and the spring 115 will also be compressed. When the telescopic rod 114 retracts to its final position, the four clamping blocks 116 will firmly clamp the water meter glass. This allows for easy installation and disassembly of the water meter glass, providing a clamping and fixing solution that improves safety and stability during operation, while also increasing operational efficiency. After use, the device needs protection. The slider 201 is inserted into the protective housing 11. When the slider 201 contacts the center rod 202, it pushes the center rod 202 to move. As the slider 201 moves, the fixing plate 204 fixed to its outer wall also moves. At this time, the semi-circular locking block 205 fixed to the outer wall of the fixing plate 204 also moves. When the semi-circular locking block 205 moves to a suitable distance, the protruding part of the semi-circular locking block 205 pushes the convex... The clamping block 210 and the concave clamping block 209 rotate outward on the surface of the rotating rod 208. At the same time, the two springs 207 located at the height of the outer wall of the extension plate 211 are also compressed. When the semi-circular locking block 205 is inserted into the concave clamping block 209 and the convex clamping block 210, the springs 207 will push the extension plate 211 to move, thereby pushing the convex clamping block 210 and the concave clamping block 209 toward each other, thus fixing the device inside the protective housing 11. When the device needs to be used, the pressing block 203 can be pushed to push out the slider 201. Its advantage is that the device is protected when it is not in use, preventing the device from being damaged by bumps.
