Description

Technical Field

[0001] This utility model relates to the field of electrical installation technology, specifically to an electrical installation sleeve. Background Technology

[0002] Electrical installation sleeves are tools used to install and remove screws or nuts from certain equipment. When installing electrical equipment in substations, sleeves are generally used to remove screws and nuts that are difficult to handle by hand.

[0003] Existing electrical installation sites often have various conditions, and a single sleeve cannot meet all these conditions, nor can it be used to expand the applicability of screws and nuts of different specifications. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an electrical installation sleeve that solves the problem that a single sleeve cannot meet multiple conditions and cannot be used for screws and nuts of different specifications. By setting up a first sleeve and a second sleeve, the applicability of screws and nuts of different specifications is expanded.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrical installation sleeve, comprising a handle assembly, a sleeve assembly, and a positioning assembly. The handle assembly includes a handle tube, the sleeve assembly includes an outer ring, and the positioning assembly includes an adjusting side plate and a positioning post. A mounting plate is symmetrically welded to the bottom of the handle tube. An installation hole is formed on the inner wall of the mounting plate, and an inner mounting groove is formed on the inner side of the handle tube. One end of the outer ring is connected to a first sleeve, and the end of the outer ring away from the first sleeve is connected to a second sleeve. A positioning hole is formed on the inner side of the second sleeve. A limiting outer plate is welded to the outer wall of the positioning post. The end of the positioning post away from the limiting outer plate passes through the inner mounting groove and extends to be welded to the inner wall of the adjusting side plate. An adjusting inner plate is welded to the outer wall of the positioning post located inside the inner mounting groove, and a compression spring is sleeved on the outer wall of the positioning post located inside the inner mounting groove.

[0006] The beneficial effects of this utility model are as follows: When the first sleeve is needed, the outer ring is rotated to rotate the first sleeve so that its opening is vertically downward. The positioning pin is used to limit and fix the second sleeve located inside the mounting plate. When the second sleeve is used, the second sleeve is rotated so that its opening is vertically downward. At this time, the first sleeve is rotated into the mounting plate. The positioning pin is used to limit and fix the first sleeve. By setting the first sleeve and the second sleeve, the applicability range of screws and nuts of different specifications is expanded.

[0007] To enable the tightening or loosening of screws or nuts by rotating the handle tube via the lever:

[0008] As a further improvement to the above technical solution: the handle tube has a cylindrical hollow structure, and a through-hole groove is opened on the upper inner side of the handle tube away from the mounting plate. The inner wall of the through-hole groove is connected to a protective inner ring of rubber material by industrial glue.

[0009] The beneficial effects of this improvement are as follows: when the device is used vertically and a large torque is required, the extension rod is passed through the through-hole groove, and the extension rod is in close contact with the protective inner ring, increasing the friction and preventing slippage. The extension rod drives the handle tube to rotate, thereby realizing the tightening or loosening of screws or nuts.

[0010] In order to place the nut on the magnetic plate, the magnetic plate is used to attract the nut:

[0011] As a further improvement to the above technical solution: the outer wall of the grip tube is symmetrically connected with a magnetic suction plate made of neodymium iron boron magnet, and the magnetic suction plate is located between the two adjustment side plates.

[0012] The beneficial effects of this improvement are: during electrical installation work, after the nut is removed, it can be placed on the magnetic plate and attracted by the magnetism of the magnetic plate, thus preventing the nut from falling and being lost. When installing the nut, it can also be attracted to the magnetic plate first for easy access.

[0013] To achieve rotational adjustment of the positions of the first and second sleeves:

[0014] As a further improvement to the above technical solution: the outer ring is rotatably connected to the mounting plate via a rotating shaft, the rotating shaft passing through the outer ring and extending to be rotatably connected to both mounting plates simultaneously via a deep groove ball bearing.

[0015] The beneficial effects of this improvement are as follows: the outer ring is used to install and fix the first sleeve and the second sleeve. When it is necessary to switch the use of the sleeve, the outer ring is rotated. Under the action of the bearing, the outer ring rotates more smoothly, thereby realizing the rotational adjustment of the use position of the first sleeve and the second sleeve.

[0016] To improve the applicability to screws and nuts of different sizes by using the first and second sleeves:

[0017] As a further improvement to the above technical solution: the first sleeve and the second sleeve are symmetrically welded to both ends of the outer ring, and positioning holes are symmetrically opened on the inner side of the first sleeve.

[0018] The beneficial effects of this improvement are as follows: When the first sleeve is needed, the outer ring is rotated to rotate the first sleeve so that its opening is vertically downward. The positioning pin is used to limit and fix the second sleeve located inside the mounting plate. When the second sleeve is used, the second sleeve is rotated so that its opening is vertically downward. At this time, the first sleeve is rotated into the mounting plate. The positioning pin is used to limit and fix the first sleeve. By setting the first and second sleeves, the applicability range of screws and nuts of different specifications is improved.

[0019] To adjust the force applied to the side plate and move the positioning column, thus enabling operation of the positioning column:

[0020] As a further improvement to the above technical solution: the adjustment side plates are symmetrically arranged on both sides of the handle tube, and each adjustment side plate is slidably connected to the handle tube through two longitudinal positioning posts. The inner side of the outer wall of the adjustment side plate is inlaid with a 3mm thick rubber anti-slip pad layer, and the inner curvature of the adjustment side plate matches the outer curvature of the handle tube.

[0021] The beneficial effects of this improvement are as follows: After completing the rotation of the sleeve assembly, the operator holds both adjustment side plates at the same time. Due to the presence of the anti-slip pad, the friction between the hand and the adjustment side plates is increased, making it easier to apply force. The operator applies force to move the two adjustment side plates gradually closer to the outer wall of the handle tube. After the adjustment side plates are subjected to force, they push the positioning column to move, thereby realizing the operation of the positioning column and controlling the fixing and switching of the sleeve assembly.

[0022] The mounting groove is used to install the compression spring and the adjusting inner plate:

[0023] As a further improvement to the above technical solution: the inner side of the mounting plate is provided with an inner mounting groove, the positioning post passes through the inner mounting groove and is slidably connected to the handle tube through sliding cooperation with the inner wall of the inner mounting groove, and the adjusting inner plate and the compression spring are both arranged inside the inner mounting groove.

[0024] The beneficial effects of this improvement are as follows: by installing the inner groove for installing the compression spring and the adjusting inner plate, the compression spring is compressed when subjected to external force, and when the external force disappears, the compression spring returns to its original shape, which is used to drive the positioning pin to reset, so that the positioning pin is re-inserted into the positioning hole and the sleeve assembly is fixed.

[0025] In order to compress the spring to reset and release the elastic potential energy, thereby moving the adjusting inner plate to reset and releasing the positioning pin from the sleeve assembly:

[0026] As a further improvement to the above technical solution: one end of the compression spring is connected to the adjusting inner plate by welding, and the end of the compression spring away from the adjusting inner plate is connected to the inner wall of the mounting groove by welding.

[0027] The beneficial effects of this improvement are as follows: when the operator pushes the adjusting side plate, the positioning column moves and drives the adjusting inner plate to move. At the same time, the adjusting inner plate compresses the compression spring during this process, causing the compression spring to store elastic potential energy. When the adjusting side plate is released, the compression spring resets and releases the elastic potential energy, driving the adjusting inner plate to move and reset, thereby releasing the positioning column from limiting and fixing the sleeve assembly, and preparing for the next use of the sleeve assembly.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, an electrical installation sleeve includes a handle assembly 1, a sleeve assembly 2, and a positioning assembly 3. The handle assembly 1 includes a handle tube 11, the sleeve assembly 2 includes an outer ring 21, and the positioning assembly 3 includes an adjusting side plate 31 and a positioning post 33. A mounting plate 14 is symmetrically welded to the bottom of the handle tube 11. The inner wall of the mounting plate 14 has mounting holes 15, and the inner side of the handle tube 11 has an inner mounting groove 16. One end of the outer ring 21 is connected to a first sleeve 22, and the end of the outer ring 21 away from the first sleeve 22 is connected to a second sleeve 23. The inner side of the second sleeve 23 has a positioning hole 24. The outer wall of the positioning post 33 is welded with a limiting outer plate 34. One end of the positioning post 33 away from the limiting outer plate 34 passes through the mounting inner groove 16 and extends to be welded to the inner wall of the adjusting side plate 31. An adjusting inner plate 36 is welded to the outer wall of the positioning post 33 located inside the mounting inner groove 16. A compression spring 35 is sleeved on the outer wall of the positioning post 33 located inside the mounting inner groove 16. The handle tube 11 has a cylindrical hollow structure. A through-hole groove 12 is opened on the upper inner side of the handle tube 11 away from the mounting plate 14. The inner wall of the through-hole groove 12 is connected to a rubber protective inner ring 17 by industrial glue. When the device is used vertically and a large torque is required, The lever passes through the through-hole slot 12, and the lever makes close contact with the protective inner ring 17 to increase friction and prevent slippage. The lever drives the handle tube 11 to rotate, thereby enabling the tightening or loosening of screws or nuts. The outer wall of the handle tube 11 is symmetrically connected with a neodymium iron boron magnet magnetic plate 13, which is located between two adjusting side plates 31. During electrical installation, after the nut is removed, it can be placed on the magnetic plate 13, and the magnetism of the magnetic plate 13 will attract the nut, preventing it from falling or being lost. When installing the nut, it can also be attracted to the magnetic plate 13 first for easy access. The outer ring 21 is rotatably connected to the mounting plate 14 via a rotating shaft 25. The rotating shaft 25 passes through the outer ring 21 and extends to be rotatably connected to both mounting plates 14 via a deep groove ball bearing. The outer ring 21 is used to install and fix the first sleeve 22 and the second sleeve 23. When it is necessary to switch the use of the sleeves, the outer ring 21 is rotated. Under the action of the bearing, the rotating shaft 25 makes the outer ring 21 rotate more smoothly, thereby realizing the rotational adjustment of the use position of the first sleeve 22 and the second sleeve 23. The first sleeve 22 and the second sleeve 23 are symmetrically welded to both ends of the outer ring 21. The inner side of the first sleeve 22 is symmetrically provided with positioning holes 24.When the first sleeve 22 is needed, rotate the outer ring 21 to rotate the first sleeve 22 until its opening is vertically downward. Use the positioning pin 33 to limit and fix the second sleeve 23 located inside the mounting plate 14. When using the second sleeve 23, rotate the second sleeve 23 until its opening is vertically downward. At this time, the first sleeve 22 rotates into the mounting plate 14, and the positioning pin 33 limits and fixes the first sleeve 22. The arrangement of the first sleeve 22 and the second sleeve 23 improves the applicability to screws and nuts of different specifications. The adjusting side plates 31 are symmetrically arranged on both sides of the handle tube 11. Each adjusting side plate 31 is connected by two longitudinal... The positioning pin 33 is slidably connected to the handle tube 11. A 3mm thick rubber anti-slip pad 32 is embedded on the inner side of the outer wall of the adjusting side plate 31. The inner curvature of the adjusting side plate 31 matches the outer curvature of the handle tube 11. After rotating the sleeve assembly 2, the operator simultaneously grips both adjusting side plates 31. Due to the presence of the anti-slip pad 32, the friction between the hand and the adjusting side plates 31 is increased, facilitating the application of force. The operator applies force to gradually move the two adjusting side plates 31 closer to the outer wall of the handle tube 11. Upon receiving force, the adjusting side plates 31 push the positioning pin 33 to move, thus controlling the operation of the positioning pin 33 and consequently controlling the movement of the adjusting side plate 31. For fixing and switching the sleeve assembly 2, the inner side of the mounting plate 14 has an inner mounting groove 16. The positioning pin 33 passes through the inner mounting groove 16 and slides with the inner wall of the inner mounting groove 16 to achieve a sliding connection with the handle tube 11. The adjusting inner plate 36 and the compression spring 35 are both located inside the inner mounting groove 16. The inner mounting groove 16 is used to install the compression spring 35 and the adjusting inner plate 36. When the compression spring 35 is subjected to external force, it is compressed. When the external force is removed, the compression spring 35 returns to its original shape, which drives the positioning pin 33 to reset, so that the positioning pin 33 is re-inserted into the positioning hole 24, fixing the sleeve assembly 2. One end of the spring 35 is welded to the inner adjusting plate 36, and the end of the compression spring 35 away from the inner adjusting plate 36 is welded to the inner wall of the mounting groove 16. When the operator pushes the adjusting side plate 31, the positioning column 33 moves and drives the inner adjusting plate 36 to move. At the same time, the inner adjusting plate 36 compresses the compression spring 35, causing the compression spring 35 to store elastic potential energy. When the adjusting side plate 31 is released, the compression spring 35 resets and releases the elastic potential energy, driving the inner adjusting plate 36 to move and reset, thereby releasing the positioning column 33 from limiting and fixing the sleeve assembly 2, and preparing for the next use of the sleeve assembly 2.

[0037] The working principle of this utility model is as follows: When the first sleeve 22 is needed, the outer ring 21 is rotated to rotate the first sleeve 22 until its opening is vertically downward. The positioning pin 33 is used to limit and fix the second sleeve 23 located inside the mounting plate 14. When the second sleeve 23 is used, the second sleeve 23 is rotated until its opening is vertically downward. At this time, the first sleeve 22 rotates into the mounting plate 14, and the positioning pin 33 is used to limit and fix the first sleeve 22. Through the setting of the first sleeve 22 and the second sleeve 23, the applicability range of screws and nuts of different specifications is improved. After the rotation for using the sleeve assembly 2 is completed, the operator holds the two adjusting side plates 3 at the same time. 1. Due to the presence of the anti-slip pad 32, the friction between the hand and the adjusting side plate 31 is increased, facilitating the application of force. The operator applies force to gradually move the two adjusting side plates 31 closer to the outer wall of the handle tube 11. After being subjected to force, the adjusting side plates 31 push the positioning pin 33 to move, thus controlling the operation of the positioning pin 33 and consequently controlling the fixing and switching of the sleeve assembly 2. When the operator pushes the adjusting side plate 31, the positioning pin 33 moves, causing the adjusting inner plate 36 to move. Simultaneously, during this process, the adjusting inner plate 36 compresses the compression spring 35, causing the compression spring 35 to store elastic potential energy. When the adjusting side plate 31 is released, the compression spring 35 resets and releases its elastic potential energy. Yes, it can move and reset the adjusting inner plate 36, thereby releasing the positioning pin 33 from limiting and fixing the sleeve assembly 2, preparing for the next use of the sleeve assembly 2. The inner groove 16 is used to install the compression spring 35 and the adjusting inner plate 36. The compression spring 35 is compressed when subjected to external force, and when the external force is removed, the compression spring 35 returns to its original shape, which drives the positioning pin 33 to reset, so that the positioning pin 33 is re-inserted into the positioning hole 24 to fix the sleeve assembly 2. The outer ring 21 is used to install and fix the first sleeve 22 and the second sleeve 23. When it is necessary to switch the sleeves, the outer ring 21 is rotated, and the rotating shaft 25 is supported by the bearing. This allows the outer ring 21 to rotate more smoothly, thereby enabling rotational adjustment of the positions of the first sleeve 22 and the second sleeve 23. When the device is used vertically and requires a large torque, the force-adding rod is passed through the through-hole groove 12, and the force-adding rod is in close contact with the protective inner ring 17 to increase friction and prevent slippage. The force-adding rod drives the handle tube 11 to rotate, thereby enabling the tightening or loosening of screws or nuts. During electrical installation, after the nut is removed, it can be placed on the magnetic plate 13, and the magnetism of the magnetic plate 13 will attract the nut, preventing it from falling or being lost. When installing the nut, it can also be attracted to the magnetic plate 13 first for easy access.
