Description

Technical Field

[0001] The utility model belongs to the technical field of fuse installation, and particularly relates to a convenient installation mechanism for a drop-out fuse. Background Technique

[0002] A fuse is a circuit protection device. When the current in the circuit exceeds a predetermined value, it will melt due to overheating, thereby cutting off the circuit and protecting the circuit from damages caused by faults such as overload or short circuit. A fuse consists of a fuse element and a fuse tube, etc. The fuse element is the core component. When the current is too large, the fuse element will melt due to overheating and cut off the circuit.

[0003] Referring to the patent CN221427667U, a convenient installation mechanism for a drop-out fuse, which discloses a concrete pole, a hoop, a concrete pole frame, an adjustment chute, a drop-out fuse, a support frame and an adjustment bracket. A hoop is connected to the outer circle of the concrete pole by bolts, a concrete pole frame is fixedly installed on the side of the hoop, adjustment chutes are embedded in the front and rear of the side of the concrete pole frame, a drop-out fuse is arranged on the side of the concrete pole frame, and there are several drop-out fuses, which are arranged in an equidistant and parallel manner. In the utility model, after adjusting the drop-out fuse to a suitable installation position, the limit holder is loosened, so that the damping telescopic concrete pole B and the outer spring pop out, and the limit holder slides into the inner side of one of the relative limit slots to limit and lock the drop-out fuse. And then, the position spacing of other drop-out fuses is adjusted in the same way, which is convenient for the staff to freely adjust the spacing of the drop-out fuses for use, and avoids the interference of the wiring of several drop-out fuses with each other.

[0004] In the above patent, an adjustment chute is used to adjust and install the fuse. Although it can enable the staff to freely adjust the spacing of the drop-out fuses, there is no preliminary positioning function during installation, so the staff needs to manually support the installation, which increases the difficulty of single-person operation. In this patent, a horizontal installation method is adopted, which changes the angle of the entire installation arm. However, when installing the fuse itself, it needs to be arranged obliquely. The reason for setting an inclination angle when installing the fuse is that when the fuse wire in the fuse melts, the fuse tube needs to quickly drop to cut off the circuit. By setting an inclination angle, the fuse tube can quickly drop by its own weight, so as to realize the timely cut-off of the circuit. If there is no inclination angle or the inclination angle is too small, the fuse tube may not be able to drop smoothly, resulting in the circuit not being cut off in time, and further possibly causing more serious faults or accidents. Content of the Utility Model

[0005] The purpose of the utility model is to provide a convenient installation mechanism for a drop-out fuse to solve the positioning and installation problems in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A convenient installation mechanism for a drop - type fuse, including an insulating column and an installation beam inside the drop - type fuse. An installation arm is provided on one side of the insulating column, and a pressing end is provided on one side of the installation arm. A support beam is installed on the surface of the installation beam, and the surface of the support beam is used to install the pressing end. A turning plate is hinge - connected to one side of the support beam. Elliptical grooves are provided on the surfaces of the turning plate, the support beam, and the pressing end. The other side of the turning plate is installed with a bracket mechanism, and the bracket mechanism is used to hold the installation arm.

[0008] Further, the support beam is in an L - shaped structure, and the short side of the support beam is welded and fixed to the installation beam. A reinforcing rib is provided on one side of the short side of the support beam, and an extension arm is fixed on one side of the reinforcing rib. An installation ear is provided on the left side of the turning plate, and the installation ear is hinge - connected to the extension arm.

[0009] Further, the bracket mechanism includes bent arms. The bent arms are symmetrically fixed on both sides of the turning plate. One end of the bent arm is fixed with a first arc - shaped support block, and a second arc - shaped support block is provided at one end of the first arc - shaped support block. Connecting arms are provided at the bottom ends of the first arc - shaped support block and the second arc - shaped support block.

[0010] Further, side columns are symmetrically arranged on the outer side of the installation arm. When the installation arm is inserted into the first arc - shaped support block and the second arc - shaped support block, the side columns are between the first arc - shaped support block and the second arc - shaped support block. In this way, when the installation arm is moved, the side columns can limit the maximum displacement distance and the minimum displacement distance, and the installation arm will not be detached when the turning plate is flipped, improving the stability of the overall function.

[0011] Further, the bent arm serves as a handle. In this way, when the turning plate is flipped, it is convenient to apply force to the bent arm to flip the turning plate.

[0012] The technical solution of the present utility model has the following beneficial effects:

[0013] 1. By using this bracket mechanism, it is not necessary to manually hold the installation arm when installing the fuse, which reduces the convenience of single - person operation. Only need to insert the installation arm into the bracket mechanism to achieve an automatic and stable effect. Then flip the turning plate to closely fit the pressing end on the surface of the support beam, and finally tighten the bolts in the elliptical groove.

[0014] 2. When the installation arm is inserted into the first arc - shaped support block and the second arc - shaped support block, the side columns are between the first arc - shaped support block and the second arc - shaped support block. In this way, when the installation arm is moved, the side columns can limit the maximum displacement distance and the minimum displacement distance, and the installation arm will not be detached when the turning plate is flipped, improving the stability of the overall function.

Specific embodiments

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1:

[0024] Refer to Figures 1 - 4 , a convenient installation mechanism for a drop fuse, including an insulating column 10 and a mounting beam 101 inside the drop fuse. A mounting arm 11 is provided on one side of the insulating column 10, a pressing end 12 is provided on one side of the mounting arm 11, a support beam 14 is mounted on the surface of the mounting beam 101, and the surface of the support beam 14 is used to mount the pressing end 12. A turning plate 17 is hingedly connected to one side of the support beam 14. Among them, elliptical grooves 13 are provided on the surfaces of the turning plate 17, the support beam 14, and the pressing end 12;

[0025] In the above solution, the installation beam 101 is a welded sheet metal frame on a utility pole. When installing the fuse, place the pressing end 12 on the surface of the support beam 14, and rotate the flipping plate 17 so that the flipping plate 17 presses above the pressing end 12. In this way, bolts can be directly inserted into the elliptical groove 13, and finally the bolts are tightened with nuts as Figure 3 shown to complete the installation of the fuse. The flipping plate 17 is hinge-connected to the support beam 14, and combined with the use of the elliptical groove 13, the installation and disassembly process of the fuse is greatly simplified. The operator can quickly place the pressing end 12 on the support beam 14, and then achieve preliminary positioning by flipping the flipping plate 17. The surfaces of the pressing end 12, the support beam 14, and the flipping plate 17 are all designed with elliptical grooves 13. These elliptical grooves 13 not only facilitate the insertion and tightening of bolts, but also provide a certain degree of tolerance space to allow for slight deviations during the installation process, while ensuring stability after tightening.

[0026] For further reference Figure 4 , the support beam 14 is in an L-shaped structure. The short side of the support beam 14 is welded and fixed to the installation beam 101. One side of the short side of the support beam 14 is provided with a reinforcing rib 15, and an extension arm 16 is fixed on one side of the reinforcing rib 15. An installation ear 18 is provided on the left side of the flipping plate 17, and the installation ear 18 is hinge-connected to the extension arm 16.

[0027] In the above solution, the support beam 14 is designed in an L-shaped structure. This structure not only provides a stable support surface for the pressing end 12 to be placed, but also ensures the stability of the entire installation structure through the welding and fixing of its short side to the installation beam 101. In addition, the addition of the reinforcing rib 15 further enhances the strength and rigidity of the support beam 14, preventing deformation or damage during installation and use. At the same time, the extension arm 16 on the reinforcing rib 15 is also used to facilitate the installation with the installation ear 18. The design of the extension arm 16 makes the installation position of the flipping plate 17 more flexible. The combined design of the L-shaped support beam 14 and the reinforcing rib 15 helps to optimize the force distribution of the entire installation structure. When tightening the bolts, the force can be transmitted more evenly to the support beam 14 and the installation beam 101, reducing the possibility of local stress concentration, thereby extending the service life of the structure.

[0028] Refer to Figure 3 and Figure 4 , a bracket mechanism is installed on the other side of the flipping plate 17, and the bracket mechanism is used to hold the installation arm 11. The bracket mechanism includes bending arms 19, which are symmetrically fixed on both sides of the flipping plate 17. One end of the bending arm 19 is fixed with a first arc-shaped support block 20, one end of the first arc-shaped support block 20 is provided with a second arc-shaped support block 21, and a connecting arm 22 is provided at the bottom ends of the first arc-shaped support block 20 and the second arc-shaped support block 21.

[0029] In the above solution, the mounting arm 11 is placed on the surfaces of the first arc-shaped support block 20 and the second arc-shaped support block 21. The mounting arm 11 can freely slide on the surfaces of the first arc-shaped support block 20 and the second arc-shaped support block 21. Push the mounting arm 11 so that the pressing end 12 is on the surface of the support beam 14. The first arc-shaped support block 20 and the second arc-shaped support block 21 support the mounting arm 11 from below, and the flipping plate 17 is above the stable pressing end 12. The two form a stable structural space, so that the mounting arm 11 will not fall off the bracket mechanism and can only slide back and forth. Only need to push the mounting arm 11 to adjust the position of the pressing end 12, so as to adjust the position of the elliptical groove 13, which simplifies the adjustment process. Using this bracket mechanism, it is not necessary to manually hold the mounting arm 11 when installing the fuse, which reduces the convenience of single-person operation. Only need to insert the mounting arm 11 into the bracket mechanism to achieve an automatic and stable effect. Then flip the flipping plate 17 to closely fit the pressing end 12 on the surface of the support beam 14. Finally, tighten the bolt in the elliptical groove 13.

[0030] For further reference Figure 5 , there are side columns 23 symmetrically on the outer side of the mounting arm 11. When inserting the mounting arm 11 into the first arc-shaped support block 20 and the second arc-shaped support block 21, the side columns 23 are between the first arc-shaped support block 20 and the second arc-shaped support block 21. In this way, when moving the mounting arm 11, the side columns 23 can limit the maximum displacement distance and the minimum displacement distance, and the mounting arm 11 will not be disengaged when flipping the flipping plate 17, improving the stable effect of the overall function.

[0031] The specific implementation process of this embodiment is as follows:

[0032] Place the mounting arm 11 on the surfaces of the first arc-shaped support block 20 and the second arc-shaped support block 21. Push the mounting arm 11 so that the pressing end 12 is on the surface of the support beam 14. The first arc-shaped support block 20 and the second arc-shaped support block 21 support the mounting arm 11 from below, and the flipping plate 17 is above the stable pressing end 12. Flip the flipping plate 17 to closely fit the pressing end 12 on the surface of the support beam 14. Finally, tighten the bolt in the elliptical groove 13 to complete the installation.

[0033] Embodiment 2:

[0034] Refer to Figure 4 , the bending arm 19 acts as a handle. In this way, it is convenient to flip the flipping plate 17 by applying force to the bending arm 19 when flipping the flipping plate 17.
