The spring steel ruler in the present application is a standard part or a modified part of the steel ruler in the pa pa ruler / pat pa ruler that can be obtained through channels in the prior art.

[0034] See also Figure 4 , 8 , 9 and 10, the embodiment of the present invention provides a distribution line insulation sheath, used for a distribution line 1, including a branch sheath 4, the branch sheath 4 includes a ruler sleeve 5 and a spring steel ruler 6, the ruler sleeve 5 is wrapped around the outside of the spring steel ruler 6, and the spring steel ruler 6 can be repeatedly overlapped and wrapped around the exposed part 2 in the circumferential direction after being hit by the distribution line 1;

[0035] The branch sheath 4 also includes a connector 7, which has two connectors 7, which are fixed at both ends of the ruler sleeve 5 with grooves facing outward, and a first slider 8 and a second slider 9 are slidably installed inside the two connectors 7, respectively. The two adjacent branch sheaths 4 are connected along the length direction by the engagement of the first slider 8 and the second slider 9 to form an insulating sheath body 3, and any of the branch sheaths 4 can reciprocate in the width direction. The insulating sheath body 3 can be repeatedly overlapped and wound around the exposed part 2 in the circumferential direction, and can also be overlapped and wound around the exposed part 2 in the axial direction.

[0036] The present invention improves and designs a branch sheath based on the structure of the snap ruler / pat ruler, and utilizes the elastic deformation characteristics of the snap ruler / pat ruler when it is subjected to force, that is, winding and wrapping, to achieve the purpose of quickly wrapping the branch sheath around the conductor, improve the working efficiency of insulation management and protection, reduce the physical and mental consumption of operators, reduce the equipment investment cost, shorten the insulation treatment time of the distribution line, and has good economic benefits;

[0037] A plurality of branch sheaths are spliced ​​together along the length direction to form a linear insulating sheath main body. The relative displacement difference between two adjacent branch sheaths is changed by sliding left and right, thereby adjusting the line shape of the entire insulating sheath main body, so that it can be repeatedly wrapped and overlapped around the circumference of the distribution line to meet the wrapping protection requirements for the exposed thickness of the exposed parts, and can also be wrapped and overlapped around the axial direction of the distribution line to meet the wrapping protection requirements for the exposed length of the exposed parts, and can also achieve both and meet the wrapping protection requirements for the exposed thickness and exposed length of the exposed parts at the same time, and has better ductility and adaptability.

[0038] See also Figure 1 In this embodiment, when the branch sheaths 4 are slid left and right to align, the insulating sheath body 3 forms a straight line.

[0039] With such a design, if a worker holds the insulating sheath body 3 in a straight shape and taps the exposed portion 2 with a deeper exposure depth on the distribution line 1, the spring steel ruler 6 in the branch sheath 4 in each section will be bent by the force and form a circle around the distribution line 1. In this way, the insulating sheath body 3 can be repeatedly wrapped and overlapped around the circumference at the same position of the exposed portion 2, thereby meeting the wrapping protection requirements for the exposed thickness of the exposed portion 2.

[0040] See also Figure 1-4 In this embodiment, when each branch sheath 4 slides freely left and right, the insulating sheath body 3 forms a distorted curve.

[0041] With such a design, if a worker holds the curved insulating sheath body 3 and hits the exposed part 2 on the distribution line 1, the spring steel ruler 6 in each section of the branch sheath 4 will be bent by the force and hug the distribution line 1 in a circle at their respective positions. In this way, the multiple branch sheaths 4 in the insulating sheath body 3 are repeatedly wrapped and overlapped in the circumferential direction, and are also wrapped in an axial spiral and overlapped manner, while meeting the wrapping protection requirements for the exposed thickness and exposed length of the exposed part 2.

[0042] See also Figure 2-3 In this embodiment, when each of the branch sheaths 4 slides to the left and is in place, the insulating sheath body 3 forms an oblique straight line that is skewed to the left from top to bottom along the length direction;

[0043] When each of the branch sheaths 4 slides rightward to its proper position, the insulating sheath body 3 forms an oblique straight line that is tilted rightward from top to bottom along the length direction.

[0044] With such a design, if a worker holds the insulating sheath body 3 in an oblique straight line shape and hits the exposed portion 2 with a longer exposed length on the distribution line 1, the spring steel ruler 6 in the branch sheath 4 in each section will bend under the force and form a circle around the distribution line 1 at their respective positions. In this way, the insulating sheath body 3 can be wrapped around the axial spiral in an overlapping manner along the length direction outside the exposed portion 2, thereby meeting the wrapping protection requirements for the exposed length of the exposed portion 2.

[0045] See also Figure 4 In this embodiment, a slide groove 702 is provided inside the connector 7 along the width direction of the branch sheath 4 , and the first slider 8 or the second slider 9 is slidably matched with the slide groove 702 .

[0046] With this design, the two adjacently connected branch sheaths 4 change their relative positions by sliding the first slider 8 or the second slider 9 along the slide groove 702, thereby achieving a displacement difference of sliding left and right, thereby changing the overall shape of the insulating sheath body 3.

[0047] See also Figure 4-5 In this embodiment, a limiting plate 701 is provided at the notch portion of the slide groove 702 along the width direction of the branch sheath 4, and the limiting plates 701 have two, which are respectively fixed on the positive and negative inner wall surfaces of the slide groove 702, and the first slider 8 or the second slider 9 can slide and abut against the limiting plates 701.

[0048] With such a design, the limiting plate 701 provides limiting protection for the first sliding block 8 and the second sliding block 9 , thereby preventing them from falling out of the sliding groove 702 .

[0049] See also Figure 4-7 In this embodiment, a splicing sub-component 801 is fixed on the top of the first sliding block 8, the splicing sub-component 801 extends outward between the two limiting plates 701, and a clamping block 802 is fixed on the back of the splicing sub-component 801;

[0050] A splicing mother component 901 is fixed to the bottom of the second sliding block 9, the splicing mother component 901 extends outward between the two limiting plates 701, and a slot 902 is provided on the front of the splicing mother component 901;

[0051] The sub-assembly 801 and the master assembly 901 are fitted together by the sliding engagement of the clamping block 802 and the clamping groove 902 , and the sum of the overlapping thicknesses of the sub-assembly 801 and the master assembly 901 matches the gap width between the two limiting plates 701 .

[0052] With this design, the sub-assembly 801 or the female assembly 901 can pass through the gap between the two limiting plates 701 and extend outward, and synchronously slide along the slide groove 702 following the first slider 8 or the second slider 9, and the sub-assembly 801 and the female assembly 901 are fitted together, slidingly matching with the above-mentioned gap, thereby improving the compactness of the structure and avoiding looseness.

[0053] The two adjacent branch sheaths 4 are spliced ​​and connected by the buckling of the first slider 8 and the second slider 9, that is, by the sliding engagement of the clamping block 802 and the clamping groove 902. The staff can add or remove the branch sheath 4 at any time according to the actual size of the exposed part 2 on the distribution line 1, so as to adjust the length of the insulating sheath body 3, that is, adjust the thickness of the insulating sheath body 3 repeatedly overlapping and wrapping the exposed part 2 around the circumferential direction, and also adjust the length of the insulating sheath body 3 overlapping and wrapping the exposed part 2 around the axial spiral.

[0054] See also Figure 6-7 In this embodiment, the card slot 902 includes three slots a, b and c that are interconnected. The b slot is opened vertically, and the a slot and the c slot are opened horizontally and are respectively connected to the upper and lower ends of the b slot on the same side. The card block 802 slides in the order of a slot → b slot → c slot in sequence to complete the locking and fitting of two adjacent splicing sub-components 801 and the splicing mother component 901. The card block 802 can slide in the order of c slot → b slot → a slot in sequence to complete the unlocking and separation of two adjacent splicing sub-components 801 and the splicing mother component 901.

[0055] With this design, when it is necessary to splice two adjacent branch sheaths 4, firstly, one of the connectors 7 containing the first slider 8 is pressed against the bottom of the other connector 7 containing the second slider 9, and the card block 802 is slid from left to right into the groove a until it slides to the bottom, and then slid from bottom to top into the groove b until it slides to the bottom, and then slid from right to left into the groove c until it slides to the bottom, thereby, the back of the splicing sub-component 801 is completely attached to and abuts against the front of the splicing mother component 901, and the two completely overlap and slide together to be clamped between the gaps of the two limiting plates 701. Conversely, when it is necessary to disassemble the two adjacent branch sheaths 4, the reverse sliding operation is sufficient;

[0056] In this way, the connection between the two adjacent connectors 7 is strengthened through the design of the horizontal and vertical staggered grooves, which can not only prevent the branch sheaths 4 from being unhooked, but also prevent the insulating sheath body 3 from accidentally loosening when it is subjected to force to hit the distribution line 1 or when adjusting its shape.

[0057] See also Figure 5 In this embodiment, the connector 7 is made of insulating material, and both the front and back sides are provided with adhesive layers 703 for sticking the distribution line 1.

[0058] With such a design, the connector 7 is fixed at both ends of the length of the ruler sleeve 5, and its own length is consistent with the width of the ruler sleeve 5, and is connected with the ruler sleeve 5 to form an equal-width, smooth-lined whole. When the insulating sheath body 3 is wrapped around the exposed portion 2, the two connectors 7 located at the head and tail ends of the insulating sheath body 3 can be pasted and positioned with the distribution line 1 through the adhesive layer 703 to prevent the insulating sheath body 3 from being detached or shifted as a whole. The adhesive layer 703 can be made of a colloid material such as a tearable double-sided adhesive tape and a permanent adhesive tape according to project requirements. At the same time, in order to avoid an excessively large interval between two adjacent spring steel rulers 6 acting on the distribution line 1, the width of the connector 7 should not be set too wide to prevent discontinuous winding.

[0059] See also Figure 4 In this embodiment, the ruler sleeve 5 is made of a flexible insulating material with deformation ability.

[0060] In this design, the ruler sleeve 5 is wrapped around the outside of the spring steel ruler 6 and can be deformed along with the deformation of the spring steel ruler 6, thereby protecting the internal steel ruler and the operator, ensuring the safety of operation and the wear resistance and pressure resistance of the product. Suitable insulating materials such as insulating rubber, silicone or PVC can be selected according to project requirements. At the same time, in order to reduce the resistance to the bending deformation of the spring steel ruler 6, the thickness of the ruler sleeve 5 should not be set too thick.

[0061] In summary, the present invention improves and designs a branch sheath based on the structure of the snap ruler / pat ruler, and utilizes the elastic deformation characteristics of the snap ruler / pat ruler when it is subjected to force, that is, winding and winding, to achieve the purpose of quickly wrapping the branch sheath around the conductor, improve the work efficiency of insulation management and protection, reduce the physical and mental consumption of operators, reduce equipment investment costs, shorten the insulation treatment time of distribution lines, and have good economic benefits;

[0062] Multiple branch sheaths are spliced ​​together along the length direction to form a linear insulating sheath body. The relative displacement difference between two adjacent branch sheaths is changed by sliding left and right, thereby adjusting the line shape of the entire insulating sheath body, so that it can be repeatedly wrapped and overlapped around the circumference of the distribution line to meet the wrapping protection requirements for the exposed thickness of the exposed parts, and can be wrapped and overlapped around the axial direction of the distribution line to meet the wrapping protection requirements for the exposed length of the exposed parts. It can also achieve both, and meet the wrapping protection requirements for the exposed thickness and exposed length of the exposed parts at the same time, and has better ductility and adaptability;

[0063] The connection between two adjacent branch sheaths is completed by assembling the splicing joints, and then the assembly of the entire insulating sheath body is completed, which is convenient for the staff to add or remove the number of branch sheaths at any time according to the actual size of the exposed parts on the distribution line, and to adjust the length of the insulating sheath body. The installation is simple and fast, and the operation is flexible and convenient.
