Description

Technical Field

[0001] The invention relates to the technical field of electric power detection, and in particular to an electric equipment inspection instrument. Background Art

[0002] The three-phase power consumption tester is an instrument for measuring three-phase power parameters, analyzing the correctness of the protection circuit CT connection, and detecting the three-phase voltage and current imbalance. It can complete high-precision measurement of three-phase voltage, current, phase angle, frequency, power, power factor and other power parameters. What is more unique is that it can analyze the correctness of the CT connection and check the power balance of the power line. It also has the function of calculating electric energy.

[0003] To facilitate the inspection of electrical appliances, most of the existing electricity inspection instruments are configured as handheld ones, so that the inspectors can operate the electricity inspection instruments conveniently. However, in the actual electricity inspection process, the inspectors need to plug different connectors into the electricity inspection instruments, and also need to connect the inspection instruments to the inspected electrical appliances through lines. As a result, the inspectors cannot always keep the electricity inspection instruments in a handheld position during the inspection process. The inspection instruments are usually placed on a desktop or on the ground. An unfixed inspection instrument is very likely to move due to the pulling of the lines during the inspection process, and then fall from the desktop, or be stepped on after moving on the ground, increasing the risk of damage to the inspection instrument.

[0015] Preferably, an annular groove is formed on the pull handle, and a handle is fixedly mounted on one side of the inspection instrument housing.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, a clamping pad is provided and the handle is pulled to make the two sliding support seats move toward each other. The two sliding support seats moving toward each other drive the two clamping plates to approach each other through the fixed axis, and then the rod-shaped object is clamped by the clamping pad on one side of the clamping plate and limited by the limiting component. The upper structural design can quickly complete the limiting of the inspection instrument housing and the rod-shaped object, which is convenient for maintenance personnel to plug the connector into the inspection instrument housing. At the same time, during the operation of the maintenance personnel, the inspection instrument housing will not be displaced due to the pulling of the line, thereby ensuring the safe use of the inspection instrument housing and extending the service life of the inspection instrument housing.

[0018] By setting a suction cup and pulling the handle, the handle drives the piston to slide along the inner wall of the cylinder through the pull rod, thereby extracting the gas in the three-way pipe and the suction cup, and limiting the sliding piston through the limiting component, so that the suction cup is tightly attached to the plane under the action of external air pressure, thereby completing the limitation of the inspection instrument housing and the plane, making it convenient for maintenance personnel to plug the connector into the inspection instrument housing. At the same time, during the operation of the maintenance personnel, the inspection instrument housing will not be displaced due to the pulling of the line, thereby ensuring the safe use of the inspection instrument housing and extending the service life of the inspection instrument housing.

[0019] By setting the rounded corners, one side of the splint normally contacts the first limit groove and is fixed under the restriction of the fixed axis. Before fixing the inspection instrument shell to the rod-shaped object, the two splints are flipped over to rotate around the fixed axis. During the rotation, the rounded corner contacts one side of the first limit groove to play a transition role, and the reaction force generated by the contact causes the fixed axis to bend. When the splint completes the 90-degree flip, it contacts the first limit groove through the other side, thereby completing the re-fixation of the splint. It is simple and quick.

[0020] By setting the weakening groove and the retreat groove, the weakening groove and the retreat groove are deformed during the process of the rod-shaped object and the clamping plate squeezing the clamping pad, and adapt to the outer surface of the rod-shaped object, thereby improving the fixing stability of the inspection instrument shell. At the same time, a number of protrusions can be set on the contact surface between the clamping pad and the rod-shaped object to increase the friction force of the clamping pad and further improve the fixing stability of the inspection instrument shell.

[0021] By setting the sphere, the handle pulls the sphere to move toward the side away from the cylinder body, and the moving sphere drives the second limit sleeve to move toward the side away from the first limit sleeve and squeezes the spring. When the handle stops pulling, the spring causes the second limit sleeve to drive the sphere to reset through its own elastic force. The reset sphere contacts the outside of the pull rod under the squeezing of the inner wall of the third cavity, and the pull rod with a reverse movement trend is limited by the friction force of multiple spheres contacting the inner wall of the third cavity, thereby preventing the clamping pad or suction cup from loosening from the fixed object due to the movement of the pull rod after the inspection instrument shell is fixed, thereby ensuring the fixation stability of the inspection instrument shell, and the operation is simple and convenient.

[0022] By setting a second slider and pressing the second fixing rod, the limiting block drives the second limiting sleeve to move toward the side away from the first limiting sleeve through the first fixing rod, thereby driving the ball in the second limiting groove to move toward the side away from the cylinder body. The ball that loses the resistance against the inner wall of the third cavity cannot limit the pull rod by friction. At this time, the pull rod moves in the opposite direction under the action of the first limiting rod or piston, thereby releasing the clamping pad or suction cup from the fixed object. The operation is convenient, which improves the maintenance efficiency of the maintenance personnel, and the limit release speed can be accelerated by pushing the handle.

[0041] like Figure 2-3 As shown, an embodiment of the present invention provides an electrical equipment inspection instrument, an inspection instrument housing 1, a first cavity is opened on one side of the inspection instrument housing 1, a second cavity is opened in the inspection instrument housing 1, a first fixing component for fixing the inspection instrument housing 1 to a plane is installed in the first cavity, a second fixing component for fixing the inspection instrument housing 1 to a rod-shaped object is installed in the second cavity, a driving component for actuating the first fixing component and the second fixing component is installed in the inspection instrument housing 1, a limiting component for limiting the driving component is installed on the driving component, an unlocking component for releasing the limiting component from limiting the driving component is installed on the limiting component, and the first fixing component and the second fixing component are connected to the driving component.

[0042] like Figure 2-5As shown, in this embodiment, a second cavity connected to the second cavity is provided in the inspection instrument housing 1, a first slide groove and two second slide grooves are provided in the first cavity, and the two second slide grooves are symmetrical about the center of the first slide groove; the first fixed component includes two sliding support seats 2 slidably sleeved with the first slide groove, and first limiting grooves 3 are provided on adjacent two sides of the sliding support seat 2, a fixed shaft 26 is fixedly installed in the first limiting groove 3, a clamping plate 4 is rotatably sleeved on the fixed shaft 26, a fixing groove is provided on one side of the clamping plate 4, a clamping pad 5 is fixedly installed in the fixing groove, and one side of the clamping plate 4 is in conflict with the first limiting groove 3, A rounded corner is provided at one corner of the splint 4, and a first connecting rod 6 is hinged on the top and bottom of the rotating sliding support seat 2 in the first limiting groove 3. The ends of the first connecting rod 6 that are close to each other are rotatably connected to the same first sliding block 7, and the first sliding block 7 is slidably sleeved with the second sliding groove. The driving component includes a first limiting rod 8 fixedly sleeved on one of the sliding support seats 2, and a pull rod 9 that passes through and extends to the outside of the inspection instrument housing 1 is fixedly sleeved on the first limiting rod 8. The pull rod 9 is slidably sleeved with the inspection instrument housing 1, and a handle 10 is fixedly installed at one end of the pull rod 9. The handle 10 is located outside the inspection instrument housing 1, and the rounded corner is not on the same axis as the fixed axis 26.

[0043] Under normal circumstances, one side of the splint 4 is in conflict with the first limiting groove 3 and is fixed under the restriction of the fixed axis 26. Before fixing the inspection instrument housing 1 to the rod-shaped object, the two splints 4 are flipped over to allow the splint 4 to rotate around the fixed axis 26. During the rotation, the rounded corner is in conflict with one side of the first limiting groove 3 to serve as a transition, and the fixed axis 26 is bent by the reaction force generated by the conflict. After the splint 4 completes the 90-degree flip, it is in conflict with the first limiting groove 3 through the other side, thereby completing the re-fixation of the splint 4, which is simple and quick.

[0044] Then, the handle 10 is pulled, and the handle 10 drives one of the sliding support seats 2 to slide along the inner wall of the first slide groove through the pull rod 9 and the first limit rod 8. The sliding support seat 2 drives the first sliding block 7 to slide along the inner wall of the second slide groove through the first connecting rod 6, and drives the other sliding support seat 2 to slide along the inner wall of the first slide groove through the first connecting rod 6 and the first sliding block 7, so that the two sliding support seats 2 move toward each other. The two sliding support seats 2 moving toward each other drive the two clamping plates 4 to approach each other through the fixed shaft 26, and then clamp the rod-shaped object through the clamping pad 5 on one side of the clamping plate 4, and limit it under the action of the limiting component. The upper structural design can quickly complete the limiting of the inspection instrument housing 1 and the rod-shaped object, which is convenient for maintenance personnel to plug the connector into the inspection instrument housing 1. At the same time, during the operation of the maintenance personnel, the inspection instrument housing 1 will not be displaced due to the pulling of the line, which ensures the safe use of the inspection instrument housing 1 and extends the service life of the inspection instrument housing 1.

[0045] like Figure 2-6As shown, in this embodiment, the two sliding support seats 2 are symmetrical about the center of the first sliding groove, a plurality of weakening grooves are symmetrically opened on both sides of the clamping pad 5 about the center of the clamping pad 5, and retreat grooves are opened in the middle of the other two sides of the clamping pad 5.

[0046] In the process of squeezing the clamping pad 5 by the rod-shaped object and the clamping plate 4, the weakening groove and the retreat groove are deformed and adapted to the outer surface of the rod-shaped object, thereby improving the fixing stability of the inspection instrument housing 1. At the same time, a plurality of protrusions can be provided on the contact surface between the clamping pad 5 and the rod-shaped object to increase the friction force of the clamping pad 5 and further improve the fixing stability of the inspection instrument housing 1.

[0047] like Figure 4-5 As shown, in the present embodiment, the second fixed component includes a cylinder body 11 fixedly installed in the second cavity, a three-way pipe 13 is fixedly installed on the top and the bottom of the cylinder body 11, the three-way pipe 13 is connected to the cylinder body 11, and suction cups 14 are fixedly installed on both ends of the three-way pipe 13 away from the cylinder body 11, a piston 12 is slidably sleeved in the cylinder body 11, a pull rod 9 is slidably sleeved in the cylinder body 11, the pull rod 9 penetrates and extends to both sides of the cylinder body 11, the pull rod 9 is fixedly sleeved on the piston 12, the piston 12 is made of hard metal, and a sealing ring is fixedly sleeved on the piston 12.

[0048] When it is necessary to fix the inspection instrument housing 1 to the plane, the suction cup 14 is fitted to the plane, and then the handle 10 is pulled. The handle 10 drives the piston 12 to slide along the inner wall of the cylinder 11 through the pull rod 9, and then the gas in the three-way pipe 13 and the suction cup 14 is extracted. The sliding piston 12 is limited by the limiting component, and the suction cup 14 is tightly attached to the plane under the action of external air pressure, thereby completing the limitation of the inspection instrument housing 1 and the plane, which is convenient for maintenance personnel to plug the connector into the inspection instrument housing 1. At the same time, during the operation of the maintenance personnel, the inspection instrument housing 1 will not be displaced due to the pulling of the line, thereby ensuring the safe use of the inspection instrument housing 1 and extending the service life of the inspection instrument housing 1.

[0049] like Figure 4 , Figure 5 , Figure 7As shown, in the present embodiment, the limiting component includes a first limiting sleeve 15 fixedly mounted on one side of the cylinder body 11, a third cavity is defined in the first limiting sleeve 15, the third cavity is a stage-shaped component, and the smaller side of the stage-shaped component faces the cylinder body 11, a second limiting sleeve 16 is slidably sleeved in the first limiting sleeve 15 and penetrates through and extends to the outside of the first limiting sleeve 15, a plurality of second limiting grooves 17 are defined on the second limiting sleeve 16, a ball 18 is placed in the second limiting groove 17, the ball 18 is located in the third cavity, the ball 18 abuts against the inner wall of the third cavity, the ball 18 abuts against the outer side of the pull rod 9, one end of the second limiting sleeve 16 is fixedly connected to a spring 19 sleeved on the outside of the pull rod 9, and one end of the spring 19 is fixedly connected to the inner wall of the second cavity.

[0050] Depending on the different fixed objects, when the inspection instrument housing 1 is fixed to the rod-shaped object, the clamping pad 5 transmits the force to the pull rod 9 through the clamping plate 4, the fixed shaft 26, the first limiting groove 3, the sliding support seat 2, and the first limiting rod 8 through the reaction force of the rod-shaped object on the clamping pad 5, thereby making the pull rod 9 have a tendency to move in the opposite direction. When the inspection instrument housing 1 is fixed to the plane, the piston 12 makes the pull rod 9 have a tendency to move in the opposite direction under the action of the air pressure in the cylinder body 11, the tee pipe 13, and the suction cup 14.

[0051] When the pull rod 9 is moved by pulling the pull handle 10, the pull rod 9 will drive the ball 18 to move toward the side away from the cylinder body 11 through the friction force. The moving ball 18 drives the second limiting sleeve 16 to move toward the side away from the first limiting sleeve 15 and squeezes the spring 19. When the pull handle 10 stops being pulled, the spring 19 uses its own elastic force to make the second limiting sleeve 16 drive the ball 18 to reset. The reset ball 18 contacts the outer side of the pull rod 9 under the pressure of the inner wall of the third cavity. The friction force of multiple balls 18 contacting the inner wall of the third cavity limits the pull rod 9 with a reverse movement trend. This prevents the clamping pad 5 or the suction cup 14 from loosening from the fixed object due to the movement of the pull rod 9 after the inspection instrument housing 1 is fixed, thereby ensuring the fixing stability of the inspection instrument housing 1 and making the operation simple and convenient.

[0052] like Figure 2 , Figure 3 , Figure 7 , Figure 8As shown, in the present embodiment, two first fixing rods 20 are fixedly installed symmetrically about the axis of the second limiting sleeve 16 on one side of the second limiting sleeve 16, and the two first fixing rods 20 are slidably sleeved with the inspection instrument housing 1, and a limiting ring 21 is fixedly installed on one end of the two first fixing rods 20 away from the second limiting sleeve 16, and the limiting ring 21 is located outside the inspection instrument housing 1; the unlocking component includes a limiting block 22 fixedly installed on the first fixing rod 20, and one side of the inspection instrument housing 1 is slidably sleeved with two first sliding rods 23 that penetrate the inspection instrument housing 1 and extend into the second cavity, one end of the two first sliding rods 23 is fixedly installed with the same second fixing rod 24, and the other ends of the two first sliding rods 23 are fixedly installed with a second sliding block 25, the second sliding block 25 is a triangular component, and a third sliding groove is opened on one side of the limiting block 22, and the second sliding block 25 is slidably sleeved with the third sliding groove.

[0053] When the maintenance personnel completes the maintenance and needs to separate the inspection instrument housing 1 from the fixed object, they press the second fixing rod 24, and the second fixing rod 24 drives the second sliding block 25 to move through the first sliding rod 23, and the inclined surface of the second sliding block 25 squeezes the inner side of the limiting block 22, so that the limiting block 22 drives the second limiting sleeve 16 to move to the side away from the first limiting sleeve 15 through the first fixing rod 20, and then drives the ball 18 in the second limiting groove 17 to move to the side away from the cylinder body 11. The ball 18 that loses the contact with the inner wall of the third cavity cannot limit the pull rod 9 by friction. At this time, the pull rod 9 moves in the opposite direction under the action of the first limiting rod 8 or the piston 12, so that the clamping pad 5 or the suction cup 14 is released from the limit with the fixed object. The operation is convenient, which improves the maintenance efficiency of the maintenance personnel. The limit release speed can be accelerated by pushing the handle 10.

[0054] like Figure 1-3 As shown, in the present embodiment, an annular groove is provided on the handle 10, and a handle is fixedly installed on one side of the inspection instrument housing 1. The annular groove is provided to prevent the maintenance personnel from slipping when pulling the handle 10, so that the maintenance personnel can pull the handle 10 conveniently, and the handle is convenient for the maintenance personnel to hold the inspection instrument housing 1.

[0055] The technical solution provided by the present invention provides a clamping pad and pulls the handle to make the two sliding support seats move toward each other. The two sliding support seats moving toward each other drive the two clamping plates to approach each other through the fixed shaft, and then the rod-shaped object is clamped by the clamping pad on one side of the clamping plate, and limited by the limiting component. The upper structural design can quickly complete the limiting of the inspection instrument housing and the rod-shaped object, which is convenient for maintenance personnel to plug the connector into the inspection instrument housing. At the same time, during the operation of the maintenance personnel, the inspection instrument housing will not be displaced due to the pulling of the line, thereby ensuring the safe use of the inspection instrument housing and extending the service life of the inspection instrument housing.

[0056] By setting a suction cup and pulling the handle, the handle drives the piston to slide along the inner wall of the cylinder through the pull rod, thereby extracting the gas in the three-way pipe and the suction cup, and limiting the sliding piston through the limiting component, so that the suction cup is tightly attached to the plane under the action of external air pressure, thereby completing the limitation of the inspection instrument housing and the plane, making it convenient for maintenance personnel to plug the connector into the inspection instrument housing. At the same time, during the operation of the maintenance personnel, the inspection instrument housing will not be displaced due to the pulling of the line, thereby ensuring the safe use of the inspection instrument housing and extending the service life of the inspection instrument housing.

[0057] By setting the rounded corners, one side of the splint normally contacts the first limit groove and is fixed under the restriction of the fixed axis. Before fixing the inspection instrument shell to the rod-shaped object, the two splints are flipped over to rotate around the fixed axis. During the rotation, the rounded corner contacts one side of the first limit groove to play a transition role, and the reaction force generated by the contact causes the fixed axis to bend. When the splint completes the 90-degree flip, it contacts the first limit groove through the other side, thereby completing the re-fixation of the splint. It is simple and quick.

[0058] By setting the weakening groove and the retreat groove, the weakening groove and the retreat groove are deformed during the process of the rod-shaped object and the clamping plate squeezing the clamping pad, and adapt to the outer surface of the rod-shaped object, thereby improving the fixing stability of the inspection instrument shell. At the same time, a number of protrusions can be set on the contact surface between the clamping pad and the rod-shaped object to increase the friction force of the clamping pad and further improve the fixing stability of the inspection instrument shell.

[0059] By setting the sphere, the handle pulls the sphere to move toward the side away from the cylinder body, and the moving sphere drives the second limit sleeve to move toward the side away from the first limit sleeve and squeezes the spring. When the handle stops pulling, the spring causes the second limit sleeve to drive the sphere to reset through its own elastic force. The reset sphere contacts the outside of the pull rod under the squeezing of the inner wall of the third cavity, and the pull rod with a reverse movement trend is limited by the friction force of multiple spheres contacting the inner wall of the third cavity, thereby preventing the clamping pad or suction cup from loosening from the fixed object due to the movement of the pull rod after the inspection instrument shell is fixed, thereby ensuring the fixation stability of the inspection instrument shell, and the operation is simple and convenient.

[0060] By setting a second slider and pressing the second fixing rod, the limiting block drives the second limiting sleeve to move toward the side away from the first limiting sleeve through the first fixing rod, thereby driving the ball in the second limiting groove to move toward the side away from the cylinder body. The ball that loses the resistance against the inner wall of the third cavity cannot limit the pull rod by friction. At this time, the pull rod moves in the opposite direction under the action of the first limiting rod or piston, thereby releasing the clamping pad or suction cup from the fixed object. The operation is convenient, which improves the maintenance efficiency of the maintenance personnel, and the limit release speed can be accelerated by pushing the handle.
