One of the preferred embodiments of this application, as shown in Figures 1 to 7, is a small solid-sealed outdoor high-voltage vacuum circuit breaker, including a vacuum circuit breaker body 1, two sets of mounting plates 2 and at least one lead screw 6, two of which The group mounting plate 2 is slidably arranged on both sides of the bottom end of the vacuum circuit breaker body 1, that is, T-shaped blocks are fixedly installed on both sides of the top end of the mounting plate 2, and T-shaped blocks are fixed on both sides of the bottom end of the vacuum circuit breaker body 1 The T-shaped slot, the T-shaped block and the T-shaped slot form a sliding fit; while the lead screw 6 is rotatably installed at the bottom of the vacuum circuit breaker body 1, and the lead screw 6 and the mounting plate 2 are connected through threads.

When we install the vacuum circuit breaker body 1 on the support frame and need to adjust, we can turn the screw 6, and the screw 6 can move the mounting plate 2, so that two sets of mounting plates 2 can be placed on the vacuum circuit breaker body 1 to be moved and adjusted, so that it can be installed on support frame beams of different lengths, improving convenience.

It should be noted that, as shown in Fig. 2 and Fig. 3, there are various ways for the structure and quantity of the lead screw 6, including but not limited to the following two ways:

Method 1: The number of lead screw 6 is one. At this time, the lead screw 6 is rotated and installed at the middle of the bottom end of the vacuum circuit breaker body 1. At this time, the lead screw 6 is bidirectional, that is, the lead screw 6 is threaded from the middle to both sides. The directions are opposite, and the two sets of mounting plates 2 are threadedly engaged with two opposite thread segments of the lead screw 6 respectively.

When we install the vacuum circuit breaker body 1 on the support frame and need to adjust it, we only need to turn a lead screw 6, and then the lead screw 6 can drive the two sets of mounting plates 2 to move relatively or oppositely at the same time, which can be suitable for different length of support frame beams for installation.

Method 2: The number of lead screws 6 is two. At this time, the two sets of lead screws 6 are symmetrically rotated and installed on both sides of the bottom end of the vacuum circuit breaker body 1, and the two sets of mounting plates 2 and the corresponding two lead screws 6 pass through thread to fit.

When we install the vacuum circuit breaker body 1 on the support frame and need to adjust it, the corresponding mounting plate 2 can be moved by turning the corresponding lead screw 6, and then it can be installed on support frame beams of different lengths.

It should be noted that the first way is to install a lead screw 6, through which the two sets of mounting plates 2 can be moved and adjusted simultaneously, which is convenient and fast; the second way is to install two lead screws 6, that is, through the corresponding lead screw 6 6 Adjusting the corresponding mounting plate 2 can facilitate subsequent fine-tuning in actual installation; both methods can meet actual needs, and those skilled in the art can choose according to actual conditions.

In this embodiment, as shown in FIG. 1 and FIG. 4 , several mounting holes 5 are provided through the top of the mounting plate 2 near the outside. The number of mounting holes 5 is preferably two, which are symmetrically arranged on the mounting plate 2 respectively. ; During installation, the installation hole 5 corresponds to the hole on the crossbeam of the support frame, and then the bolts are passed through the installation hole 5 and the hole on the crossbeam of the support frame, and the vacuum circuit breaker body 1 can be fixedly installed on the support frame; Because the installed bolt is exposed on the mounting plate 2, in rainy and snowy weather, the upper part of the bolt is easy to adhere to rainwater, and then the connection between the mounting hole 5 and the bolt is corroded. The top of the plate 2 can be provided with a protective component 4 corresponding to the side of the mounting hole 5, and the protective component 4 can protect the bolts installed in the mounting hole 5; of course, a protective component can also be provided at the bottom of the support frame beam 4.

There are many structural modes of the limiting structure 42, including but not limited to the following two types:

Structure 1: As shown in Figure 5, the limit structure 42 includes torsion springs, wherein two torsion springs are preferably used, and the torsion springs are respectively sleeved on the outer sides of the rotating shaft 7. Under the torsion of the torsion springs, the protective cover can 41 and the mounting plate 2 are closely fitted, and then the bolts in the mounting holes 5 are protected.

Structure 2: As shown in Figure 4, the limit structure 42 includes a limit screw, a connection block is installed at the lower end of one side of the protective cover 41, a threaded hole is provided through the top of the connection block, and a top end of the mounting plate 2 is also provided. Corresponding threaded holes are provided. After the protective cover 41 is covered on the mounting plate 2, the limit screws are respectively screwed into the threaded holes on the connection block and the mounting plate 2, and then the protective cover 41 can be locked.

It should be noted that the locking effect of the structure to the protective cover 41 is not very good, but the speed of opening the protective cover 41 is very fast; while the locking effect of the second structure is good, but the opening and closing speed of the protective cover 41 is relatively fast. Slow; both structures can meet the actual needs, and those skilled in the art can choose according to the actual situation.
