[0025] EMBODIMENT

[0026] REFERENCE Figures 1-4 For the embodiment of the utility model, the embodiment provides an insulating sleeve for power transmission, comprising,

[0027] The sleeve assembly 100 comprises a connecting column 101, a card seat 102 threadedly connected to one end of the connecting column 101, a shaft sleeve 103 fixedly connected to the end of the connecting column 101, an insulator 104 fixedly connected to the side wall of the shaft sleeve 103, and a ball head 105 fixedly connected to the other end of the connecting column 101.

[0028] The adjusting assembly 200 comprises a fixing piece 201 fixedly installed on the side wall of the shaft sleeve 103, a support piece 202 hinged to the end of the fixing piece 201, a connecting piece 203 rotatably installed on the end of the support piece 202, and a screw rod 204 threadedly connected to the end of the connecting piece 203, and the connecting piece 203 is symmetrically installed on both ends of the screw rod 204.

[0029] The connecting column 101 is the core connecting component of the entire insulating sleeve, and plays a key role in series connection and stabilization of other components. The connecting column 101 is usually made of a material with high strength and good electrical insulation performance. The side wall of the clamping seat 102 is carefully provided with a clamping groove structure that accurately matches the ball head 105. The shaft sleeve 103 is firmly fixed to the end of the connecting column 101, providing a stable installation basis for other related components. The shaft sleeve 103 is generally made of a material with high strength, wear resistance and excellent insulation performance, which can effectively resist the influence of external environmental factors on internal components. The side wall provides a reliable fixing position for the insulator 104. The insulator 104 is made of high-quality insulating materials such as ceramics and silicone rubber, which have excellent electrical insulation performance and can effectively prevent current leakage, ensuring the safety of power transmission. The fixing member 201 is fixedly installed on the side wall of the shaft sleeve 103, providing installation support for other parts of the adjusting assembly 200, allowing the support member 202 to rotate flexibly within a certain range, thereby realizing the adjusting function of the angle or position of the insulating sleeve. When the hinge point of the fixing member 201 is rotated, the connecting member 203 moves together. When the lead screw 204 rotates, the connecting member 203 can move along the axial direction of the lead screw 204, and the support member 202 can be adjusted in angle, thereby realizing precise adjustment of the overall position or angle of the insulating sleeve, and finally achieving the purpose of adjusting the position or angle of the insulating sleeve.

[0030] Specifically, the adjusting assembly 200 further comprises a clamping block 205 hinged to the side wall of the fixing member 201. The clamping block 205 is clamped to the side wall of the shaft sleeve 103, and the inner side of the clamping block 205 is provided with a groove structure matching the shaft sleeve 103.

[0031] The clamping block 205 is hinged to the side wall of the fixing member 201, and the inner side is provided with a groove structure matching the shaft sleeve 103. The clamping block 205 can be tightly clamped to the side wall of the shaft sleeve 103 through the groove structure, which can further maintain the connection between the fixing member 201 and the shaft sleeve 103, and enhance the stability of the adjusting assembly 200 during operation.

[0032] Further, the adjusting assembly 200 further comprises an adjusting screw 206 hinged to the side wall of the fixing member 201, and the end of the adjusting screw 206 is clamped to the end of the clamping block 205.

[0033] When it is necessary to adjust the clamping tightness of the clamping block 205 and the shaft sleeve 103, the adjusting screw 206 can be rotated to rotate the clamping block 205 around the hinge point, thereby changing the fit between the groove and the shaft sleeve 103, and realizing flexible adjustment of the connection stability of the fixing member 201 and the shaft sleeve 103.

[0034] Further, the adjusting assembly 200 further comprises a push block 207 fixedly connected at the middle position of the screw rod 204, and a push rod 208 inserted into the sidewall of the push block 207, the push rod 208 not in contact with the insulator 104.

[0035] At the middle position of the screw rod 204, the push block 207 is fixedly connected, and the sidewall of the push block 207 is designed with a structure for inserting the push rod 208. The operator can drive the screw rod 204 to rotate by pushing the push rod 208, so as to adjust the position of the connecting piece 203, and finally achieve the purpose of adjusting the position or angle of the insulating sleeve. In order to ensure that the push rod 208 does not interfere with the normal operation of the insulator 104 during power transmission, the push rod 208 and the insulator 104 are kept in a non-contact state.

[0036] Preferably, the sleeve assembly 100 further comprises a latch rod 106 inserted into the end of the ball head 105, and the end of the latch rod 106 is inserted into the sidewall of the end of the ball head 105.

[0037] At the end of the ball head 105, a structure is provided for inserting the latch rod 106, and the end of the latch rod 106 can be stably inserted into the sidewall of the end of the ball head 105, further enhancing the reliability and stability of the connection between the ball head 105 and other components, and preventing loosening due to vibration or external force during power transmission.

[0038] It should be noted that the sidewall of the socket 102 is provided with a clamping groove structure matched with the ball head 105, and a set of sleeve assemblies 100 are connected with another set of sleeve assemblies 100 through the cooperation of the ball head 105 and the socket 102.

[0039] A set of sleeve assemblies 100 can be stably connected with another set of sleeve assemblies 100 through the cooperation of the ball head 105 and the socket 102, so as to meet the diversified requirements of the length or layout of the insulating sleeve in the power transmission line.

[0040] Preferably, the diameter of the insulator 104 is smaller than the diameter of the fixing piece 201, and the insulator 104 is not in contact with the fixing piece 201.

[0041] The diameter of the insulator 104 is designed to be smaller than the diameter of the fixing piece 201, and the insulator 104 is kept in a non-contact state with the fixing piece 201, which can avoid affecting the insulation performance of the insulator 104 due to the possible conductive hidden danger of the fixing piece 201, and is also conducive to better playing the insulation role of the insulator 104 in complex power transmission environment.

[0042] In use, during the construction of the power transmission line, first install the socket 102 on one end of the connecting column 101 through threaded connection, ensuring firm connection. Then, fix the shaft sleeve 103 on the other end of the connecting column 101, and fix the insulator 104 on the side wall of the shaft sleeve 103. When it is necessary to extend the length of the insulating sleeve or change the layout, the ball head 105 of one set of sleeve assembly 100 can be aligned with the socket 102 slot of another set of sleeve assembly 100, inserted and rotated at a certain angle to realize stable connection of the two sets of sleeve assemblies. In addition, the latch rod 106 can be inserted into the corresponding hole in the side wall of the end of the ball head 105, further enhancing the reliability of the connection and preventing accidental disconnection of the ball head 105 from the socket 102.

[0043] When it is necessary to adjust the position or angle of the insulating sleeve, the operator can rotate the lead screw 204 by turning the lever 208 inserted into the side wall of the driving block 207. Since the lead screw 204 is connected with the connecting piece 203 through threads, and the connecting piece 203 is symmetrically installed on both ends of the lead screw 204, the rotation of the lead screw 204 will make the connecting piece 203 move along the axial direction of the lead screw 204. The connecting piece 203 is rotationally connected with the support piece 202, which is in turn hinged to the end of the fixing piece 201, so the movement of the connecting piece 203 will make the support piece 202 rotate around the hinge point of the fixing piece 201, thereby realizing adjustment of the overall position or angle of the insulating sleeve. During the adjustment process, if it is necessary to enhance the stability of the connection between the fixing piece 201 and the shaft sleeve 103, the clamping block 205 can be rotated by rotating the adjusting bolt 206, so that it tightly fits with the shaft sleeve 103 through the recess on its inner side, thereby improving the stability of the connection.

[0044] In summary, the threaded connection of the socket 102 and the connecting column 101, as well as the slot fitting of the ball head 105 and the socket 102, ensures stable connection, and the latch rod 106 further enhances reliability, ensuring that the insulating sleeve connection will not loosen during power transmission, ensuring stable operation of the line. Through the cooperation of the lead screw 204, the connecting piece 203 and the support piece 202, the position and angle of the insulating sleeve can be accurately adjusted to meet different power transmission line layout and installation requirements, improving the convenience of construction and maintenance. The insulator 104 is made of high-quality insulating material, and its special design with the fixing piece 201 avoids the risk of electric conduction, effectively prevents current leakage, ensures the safety of power transmission, and reduces the risk of electrical accidents. Each component is made of high-strength material, and the fixing piece 201 and the shaft sleeve 103 are connected through the clamping block 205 and the adjusting bolt 206 to enhance the stability of the connection, so that the insulating sleeve can adapt to complex environments, prolong the service life and reduce maintenance costs. The connection between components facilitates installation and disassembly, and the adjustment of the components is simple and convenient, which facilitates adjustment and repair during power transmission line construction and maintenance, improving work efficiency.
