Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an electric wiring insulation protection device for power plant, includes first sleeve 1, second sleeve 2 and an extension section of thick bamboo 3, the left end integrated into one piece of first sleeve 1 has inlays dress ring flange 4, the right-hand member integrated into one piece of second sleeve 2 has locating flange 5, an extension section of thick bamboo 3 is two, and symmetrical slidable mounting is in the outer end of first sleeve 1 with second sleeve 2, the left end face integrated into one piece who inlays dress ring flange 4 has worn round pin 9, locating flange 5 has seted up perforation 10, locating flange 5's left end face is rotated through lock position bolt subassembly 11 and is installed chucking dish 6, wear round pin 9 and perforation 10 and mutually support, chucking dish 6 clamps the outer end of wearing round pin 9.

First sleeve 1 all adopts vulcanite insulating rubber to make with second sleeve 2, extension section of thick bamboo 3 adopts hard rubber to make, inlay dress ring flange 4 and for wearing round pin 9 to provide the installation basis, locating flange 5 provides the basis for perforating 10, and clamp dress dish 6 through the structure of self, to wearing to sell 9 and pass and carry out the card dress location behind the perforation 10, the bolt subassembly that is locked 11 will clamp dress dish 6 and locating flange 5 and make up, guarantee simultaneously that the card dress dish 6 can with carry out coaxial rotation with locating flange 5, wear round pin 9 to set up notch cooperation clamping dish through the tip and use.

Particularly, the outer end of the first sleeve 1 and the outer end of the second sleeve 2 are fixedly provided with a first locking buckle 7, and the outer end of the extension sleeve 3 is fixedly provided with a second locking buckle 8.

Can carry out effectual locking through first locking buckle 7 to the tip of first sleeve 1 and the tip of second sleeve 2, then lock an extension section of thick bamboo 3 or cable, the setting of second locking buckle 8 can lock the tip of an extension section of thick bamboo 3 to it is fixed to make up the cable of inside.

Specifically, the clamping disc 6 includes a disc ring 61, clamping edges 63 uniformly distributed on the circumference are integrally formed on the inner edge of the disc ring 61, a through groove 62 is formed between the clamping edges 63, a sliding groove 65 is formed on the ring body of the disc ring 61, and the locking bolt assembly 11 is matched with the sliding groove 65.

The ring dish is for clamping the major structure of dish 6, and the notch that round pin 9 was worn in the cooperation of screens edge 63 fixes a position, and wears the groove 62 and conveniently wears the position of crossing of round pin 9 and slide, through the rotation of dish ring 61 for screens edge 63 card is gone into the notch that wears round pin 9 or the notch that the round pin 9 was worn in the roll-off, and sliding tray 65 is the opening structure of cooperation lock position latch subassembly.

Specifically, the length of the first sleeve 1 is the same as that of the second sleeve 2, and the length of the extension tube 3 is 1.1 to 1.2 times that of the first sleeve 1.

Through the setting of length, can be effectual make the extension section of thick bamboo 3 when retracting in first sleeve 1 and second sleeve 2 completely, can leave the mounted position that the surplus made things convenient for second locking buckle 8, can't extend after avoiding retracting completely simultaneously and pull out the use.

In particular, the number of the through grooves 62 is twice the number of the through pins 9.

By doubling the number of through-slots 62, the redundant adaptation of the through-slots 62 to the through-pins 9 can be increased, which in turn leads to an increase in the ease of use of the device.

Specifically, the inner edge of the locking edge 63 is integrally formed with a limiting edge 64, the limiting edges 64 are symmetrically arranged on two sides of the through groove 62 to form a group, and the number of the group is the same as the number of the through groove 62.

Set up through spacing edge 64 and restrict the turned angle of screens edge 63, avoid crossing the unable effectual spacing effect that realizes behind the rotation, set up through the symmetry of wearing groove 62 both sides simultaneously for when the direction that card tray 6 carries out the difference rotates, the homoenergetic carries out effectual spacing.

The working principle is as follows: when the device is used, two cables to be connected are respectively sleeved through the first sleeve 1 and the second sleeve 2, the extension cylinder 3 is stretched according to the peeling amount of the cables, effective position locking is carried out through the first lock buckle and the second lock buckle 8 after the requirements are met, after the locking is finished, the embedded flange 4 and the positioning flange 5 are combined, the penetrating pin 9 penetrates through the penetrating hole 10, then the clamping disc 6 is rotated, the clamping disc 6 locks the penetrating pin 9 in position, and therefore the combined installation of the embedded flange 4, the positioning flange 5 and the extension structure of the positioning flange is achieved;

when the clamping disc 6 rotates, the disc ring 61 rotates to drive the clamping edge 63 to slide into the notch of the penetrating pin 9, and meanwhile, the rotating angle is effectively limited through the limiting edge 64, so that the penetrating pin 9 is effectively locked in position, when needing to be untied, the clamping disc 6 rotates reversely, and the sliding position of the clamping edge 63 penetrates through the notch of the penetrating pin 9.
