Description

The middle joint of the manual cable can fix the bracket

technical field

The utility model belongs to the field of electric power construction, and relates to a cable connection tool, in particular to a fixed bracket for a hand-operated cable middle joint.

Background technique

In the manufacturing process of the intermediate joint of the power cable, such as the manufacturing process of the intermediate joint of the 35kV power cable, the construction is very inconvenient due to the space location. The existing cable lifting bracket needs to be manually adjusted, and special tools such as wrenches are required. The operation is inconvenient, time-consuming and labor-intensive, which affects the construction efficiency, and it can only play a supporting role. During construction, the cable may shake off the support frame, affecting construction.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a bracket that can be fixed by the intermediate joint of the manual cable. The construction bracket has a simple structure, is easy to operate, and can improve construction efficiency.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A hand-cranked cable intermediate joint can fix the bracket, including a base, a lower support rod, a screw, an upper support rod and a stringing plate, one end of the lower support rod is symmetrically hinged on both sides of the middle part of the base, The other ends are respectively hinged with one end of the upper support rod, and the other ends of the upper support rods on both sides are hinged on the lower part of the same strut plate, and the middle part of the hinge shaft between the lower support rods and the upper support rods on both sides is hinged. A positioning plate is fixed, and the middle of the positioning plate on both sides is formed with a coaxial threaded hole and a horizontal lead screw is installed in the transverse direction. A revolving handle is fixedly installed, and the revolving handle is formed with a bend that is convenient to hold, and the height of the bracket can be adjusted by continuously turning the revolving handle.

Moreover, a spring shaft is horizontally installed on the upper end of the wiring board, and arc-shaped clips are symmetrically installed on both sides of the spring shaft.

Moreover, the base, the lower support rod, the upper support rod and the wiring board form a left-right symmetrical hinge four-bar structure.

Advantage and positive effect of the present utility model are:

The utility model is equipped with a rotary adjustable hand handle, which can adjust the height of the bracket by turning the hand handle with bare hands, and has the function of fixing cables, which brings great convenience to on-site construction, saves time and effort, and improves processing efficiency.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A fixed bracket for the intermediate joint of a hand-operated cable, including a base 8, a lower support rod 7, a screw 6, an upper support rod 5, and a stringing plate 4, as shown in attached drawings 1 to 2, the middle part of the base has two The sides are symmetrically hinged with one end of the lower support rod, and the other ends of the lower support rod are respectively hinged with one end of the upper support rod. The seat, the lower support rod, the upper support rod and the stringing plate constitute a left and right symmetrical hinge four-bar structure; the middle part of the hinge shaft between the lower support rod and the upper support rod on both sides is fixed with a positioning plate 9, The middle part of the positioning plate on both sides is made with coaxial threaded holes and a horizontal lead screw is installed horizontally. By rotating the lead screw, the positioning plates on both sides can be driven to move relatively on the lead screw, thereby driving the lower support rods on both sides. The angle between the upper support rod and the height of the bracket is adjusted.

The innovation point of the present utility model is:

One end of the lead screw protrudes from the positioning plate and a rotary handle 1 is fixedly installed at the end of the lead screw. As shown in Figure 1, the rotary handle is formed with a bend that is easy to hold, and the height of the support can be adjusted by continuously rotating the rotary handle. .

In order to prevent the cables from detaching from the bracket during construction and adjustment, a spring shaft 3 is installed horizontally on the upper end of the wiring board, and an arc clip 2 is symmetrically installed on both sides of the spring shaft, and the cables are clamped on the two sides during use. Between the arc-shaped clips, it is automatically clamped by the pre-tightening force of the spring shaft.

Although the embodiments and drawings of the utility model are disclosed for the purpose of illustration, those skilled in the art can understand that various replacements, changes and modifications can be made without departing from the spirit and scope of the utility model and the appended claims. It is possible, therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
