Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 As shown, a wiring device for electric power construction includes a support frame 1; a pay-off wheel 2 is sleeved on the outer side of the support frame 1, and a brake fixing mechanism is provided on the rear side of the support frame 1;

[0028] The brake fixing mechanism includes a storage chamber 31, which is opened on the inner wall of the rear side of the support frame 1, and an extension arm 32 is sleeved inside the storage chamber 31, and a movable groove 33 is opened on the rear side of the extension arm 32, and a screw 34 is fixedly connected inside the movable groove 33, and a screw sleeve 35 is threadedly connected to the top end of the outer side of the screw 34, and the outer side of the screw sleeve 35 is rotatably connected to a fixing seat 36, and the fixing seat 36 is fixedly connected to the rear side of the inner wall of the storage chamber 31 near the top, and the bottom end of the screw sleeve 35 is fixedly connected to a first bevel gear 37, and the first bevel gear 37 is meshed with a second bevel gear 38, and the top end of the extension arm 32 is fixedly connected to a connecting arm 41, and a brake plate 42 is provided at the top end of the front side of the connecting arm 41, and a quick-install component is provided on the connecting arm 41 and the brake plate 42, and a fixing component is provided at the front end of the support frame 1;

[0029] During operation, firstly, the knob 39 is turned to drive the second bevel gear 38 to rotate synchronously, so that the first bevel gear 37 meshing with the second bevel gear 38 rotates and drives the screw sleeve 35 to rotate synchronously, thereby making the screw rod 34 threadedly connected with the screw sleeve 35 move, and the brake plate 42 is driven to move synchronously through the extension arm 32 and the connecting arm 41, so that the brake plate 42 abuts and rubs against the pay-off wheel 2, and the pay-off wheel 2 is fixedly braked by the action of friction force.

[0030] Furthermore, a knob 39 is fixedly connected to the rear side of the second bevel gear 38, and the knob 39 passes through the support frame 1 and extends to the outside of the support frame 1. An anti-slip sleeve 40 is sleeved on the outside of the rear end of the knob 39. The anti-slip sleeve 40 is made of rubber, and anti-slip grooves are provided on the outside of the anti-slip sleeve 40.

[0031] During operation, the knob 39 facilitates the rotation of the second bevel gear 38 , and the anti-slip sleeve 40 and the anti-slip grooves on its outer side increase the friction force, making the knob 39 convenient to rotate.

[0032] Furthermore, a slider 51 is fixedly connected to the top of the front side of the inner wall of the storage cavity 31, and the slider 51 is slidably connected to the inside of a slide groove 52, and the slide groove 52 is opened on the front side of the extension arm 32;

[0033] During operation, when the extension arm 32 moves, the slider 51 fixedly connected to the inner wall of the storage chamber 31 also slides synchronously inside the slide groove 52. The combination of the slider 51 and the slide groove 52 has the effect of limiting the moving distance of the extension arm 32, thereby preventing the extension arm 32 from moving excessively and escaping from the inside of the storage chamber 31.

[0034] Further, the quick-release assembly includes an insert block 43, the insert block 43 is fixedly connected to the rear side of the brake plate 42, and the insert block 43 is inserted into the interior of the connecting arm 41, and a positioning block 44 is fixedly connected to the inner wall of the connecting arm 41, and the positioning block 44 is inserted into the interior of the positioning groove 45, and the positioning groove 45 is provided at the top of the insert block 43, and a clamping groove 46 is provided at the bottom end of the insert block 43, and the clamping groove 46 is engaged with a clamping block 47, and the clamping block 47 is sleeved inside an active cavity 48, and the active cavity 48 is provided at a position near the top of the connecting arm 41, and the top end of the clamping block 47 is fixedly connected with an anti-slip sleeve 40, and the bottom end of the clamping block 47 is fixedly connected to the top end of the first spring 49, and the top end of the clamping block 47 is fixedly connected with a pressing plate 50, and the bottom end of the first spring 49 is fixedly connected to the inner wall of the active cavity 48;

[0035] During operation, when the brake plate 42 is to be installed, the insert block 43 is first inserted into the interior of the connecting arm 41. When the insert block 43 is inserted into the interior of the connecting arm 41, the positioning block 44 is also simultaneously inserted into the interior of the positioning groove 45. The positioning block 44 and the positioning groove 45 are combined to play a positioning and guiding effect on the insert block 43 to avoid errors in the installation direction of the brake plate 42. When the insert block 43 is inserted into the interior of the connecting arm 41, the bottom end of the insert block 43 abuts against the inclined surface provided on the card block 47 and squeezes the card block 47, so that the card block 47 moves toward the interior of the active cavity 48 under the action of the squeezing force and exerts pressure on the first spring 49. The first spring 49 is squeezed to elastically deform under the action of the squeezing force. When the insert block 43 is fully inserted into the interior of the connecting arm 41, the squeezing force of the insert block 43 on the clamping block 47 disappears. At this time, the clamping block 47 is restored to its original position under the action of the restoring force of the first spring 49 and is inserted into the clamping slot 46 and engages with the clamping slot 46, thereby fixing the brake plate 42. When the brake plate 42 is to be removed and replaced, the pressing plate 50 is pressed downward to release the engagement between the clamping block 47 and the clamping slot 46, and then the brake plate 42 is pulled away from the connecting arm 41, so that the insert block 43 is disengaged from the interior of the connecting arm 41 and the brake plate 42 can be removed.

[0036] Further, the fixing assembly includes a baffle 53, which is arranged at the front end of the pay-off wheel 2, and a connecting block 54 is fixedly connected at the center position of the rear side of the baffle 53, and the connecting block 54 is inserted into the inside of the connecting groove 55, and the connecting groove 55 is opened at the front end of the support frame 1, and a fixing groove 56 is opened at the rear side of the connecting block 54, and the fixing groove 56 is engaged with a fixing card 57, and a sliding block 58 is fixedly connected to the rear side of the fixing card 57, and the sliding block 58 is sleeved inside the slide rail 59, and the slide rail 59 is fixedly connected to the inside of the sliding groove 60, and the sliding groove 60 is opened on the rear side of the inner wall of the connecting groove 55, and a second spring 61 is wound around the outer side of the slide rail 59, and the side of the second spring 61 close to the sliding block 58 is fixedly connected to the sliding block 58, and the side of the second spring 61 away from the sliding block 58 is fixedly connected to the inner wall of the sliding groove 60;

[0037] During operation, when the pay-off wheel 2 is to be fixed, the connecting block 54 is first inserted into the connecting groove 55. When the connecting block 54 is inserted into the connecting groove 55, the inner wall of the fixing groove 56 squeezes the fixing card 57, so that the fixing card 57 moves under the action of the squeezing force, and drives the fixedly connected sliding block 58 to move synchronously, so that the sliding block 58 slides inside the sliding groove 60 and squeezes the second spring 61, so that the second spring 61 is elastically deformed under the action of the squeezing force. When the connecting block 54 is fully inserted into the connecting groove 55, the squeezing force of the fixing groove 56 on the fixing card 57 disappears. At this time, the sliding block 58 returns to its original position under the action of the restoring force of the second spring 61 and drives the fixing card 57 to move synchronously. At this time, the fixing card 57 engages with the fixing groove 56, thereby fixing the baffle 53 and fixing the pay-off wheel 2.

[0038] Further, both upper and lower ends of the slide groove 52 are fixedly connected with anti-idiocy blocks 62, and the anti-idiocy blocks 62 are inserted into the anti-idiocy groove 63, and the anti-idiocy groove 63 is provided at the upper and lower ends of the inner wall of the connecting groove 55, and the inner wall of the anti-idiocy groove 63 is fixedly connected with a clamping block 64, and the clamping block 64 is designed in an arc shape, and the clamping block 64 is clamped with the clamping groove 65, and the clamping block 64 is made of rubber, and the clamping groove 65 is provided on the anti-idiocy block 62;

[0039] During operation, when the connecting block 54 is inserted into the connecting groove 55, the fool-proofing block 62 is simultaneously inserted into the fool-proofing groove 63, and the insertion direction of the connecting block 54 is determined by the fool-proofing block 62 and the fool-proofing groove 63, thereby avoiding the situation in which the pay-off wheel 2 cannot be fixed due to the wrong insertion direction of the connecting block 54. When the fool-proofing block 62 is inserted into the fool-proofing groove 63, the fool-proofing block 62 squeezes the engaging block 64 glued to the inner wall of the fool-proofing groove 63, so that the engaging block 64 made of rubber material is elastically deformed under the action of the squeezing force. When the fool-proofing block 62 is completely inserted into the fool-proofing groove 63, the squeezing force on the engaging block 64 disappears. At this time, the engaging block 64 will return to its original state under the action of its own restoring force and engage with the engaging groove 65, thereby playing the effect of auxiliary fixation of the baffle 53.

[0040] Working principle: A friction pad is glued to the bottom end of the brake plate 42, and the friction pad is made of semi-metallic friction material. For details, please refer to the brake pads of a car. When the pay-off wheel 2 is to be braked and fixed, first turn the knob 39 to drive the second bevel gear 38 to rotate synchronously, so that the first bevel gear 37 meshing with the second bevel gear 38 rotates and drives the screw sleeve 35 to rotate synchronously, thereby moving the screw rod 34 threadedly connected to the screw sleeve 35, and driving the brake plate 42 to move synchronously through the extension arm 32 and the connecting arm 41, so that the brake plate 42 abuts against the pay-off wheel 2 for friction, and the pay-off wheel 2 is fixed and braked by the action of friction.

[0041] When the extension arm 32 moves, the slider 51 fixedly connected to the inner wall of the storage chamber 31 also slides synchronously inside the slide groove 52. The combination of the slider 51 and the slide groove 52 has the effect of limiting the moving distance of the extension arm 32, thereby preventing the extension arm 32 from moving excessively and escaping from the inside of the storage chamber 31.

[0042] When the brake plate 42 is to be installed, the insert block 43 is first inserted into the interior of the connecting arm 41. When the insert block 43 is inserted into the interior of the connecting arm 41, the positioning block 44 is also simultaneously inserted into the interior of the positioning groove 45. The positioning block 44 and the positioning groove 45 are combined to guide the insert block 43 to prevent the installation direction of the brake plate 42 from being incorrect. When the insert block 43 is inserted into the interior of the connecting arm 41, the bottom end of the insert block 43 abuts against the inclined surface provided on the card block 47 and squeezes the card block 47, so that the card block 47 moves toward the interior of the active cavity 48 under the action of the squeezing force and squeezes the first spring 49 , causing the first spring 49 to produce elastic deformation under the action of the extrusion force. When the insert block 43 is fully inserted into the interior of the connecting arm 41, the extrusion force of the insert block 43 on the clamping block 47 disappears. At this time, the clamping block 47 returns to its original position under the action of the restoring force of the first spring 49 and is inserted into the clamping slot 46 and engages with the clamping slot 46, thereby fixing the brake plate 42. When the brake plate 42 is to be removed and replaced, the pressing plate 50 is pressed downward to release the clamping block 47 from the clamping slot 46, and then the brake plate 42 is pulled away from the connecting arm 41, so that the insert block 43 is removed from the interior of the connecting arm 41 and the brake plate 42 can be removed.

[0043] When the pay-off wheel 2 is to be fixed, the connecting block 54 is first inserted into the connecting groove 55. When the connecting block 54 is inserted into the connecting groove 55, the inner wall of the fixing groove 56 squeezes the fixing card 57, so that the fixing card 57 moves under the action of the squeezing force, and drives the fixedly connected sliding block 58 to move synchronously, so that the sliding block 58 slides inside the sliding groove 60 and squeezes the second spring 61, so that the second spring 61 is elastically deformed under the action of the squeezing force. When the connecting block 54 is fully inserted into the connecting groove 55, the squeezing force of the fixing groove 56 on the fixing card 57 disappears. At this time, the sliding block 58 returns to its original position under the action of the restoring force of the second spring 61 and drives the fixing card 57 to move synchronously. At this time, the fixing card 57 engages with the fixing groove 56, thereby fixing the baffle 53 and fixing the pay-off wheel 2.

[0044] When the connecting block 54 is inserted into the connecting groove 55, the fool-proofing block 62 is simultaneously inserted into the fool-proofing groove 63, and the insertion direction of the connecting block 54 is determined by the fool-proofing block 62 and the fool-proofing groove 63, thereby avoiding the situation where the pay-off wheel 2 cannot be fixed due to the wrong insertion direction of the connecting block 54. When the fool-proofing block 62 is inserted into the fool-proofing groove 63, the fool-proofing block 62 squeezes the engaging block 64 glued to the inner wall of the fool-proofing groove 63, so that the engaging block 64 made of rubber material is elastically deformed under the action of the squeezing force. When the fool-proofing block 62 is completely inserted into the fool-proofing groove 63, the squeezing force on the engaging block 64 disappears. At this time, the engaging block 64 will return to its original state under the action of its own restoring force and engage with the engaging groove 65, thereby playing the effect of auxiliary fixation of the baffle 53.
