[0001] The utility model relates to transformer technical field, concretely is a kind of transformer fence. BACKGROUND

[0002] The transformer fence is installed for the safety of personnel and transformer, equipment such as transformer station, so it is necessary to install the transformer fence. Since the place where the transformer is set is sometimes muddy bottom or unevenly poured cement, the fence cannot be stably installed beside the transformer when setting the fence. Therefore, how to adapt the uneven bottom for the transformer fence is the technical problem to be solved by the present application. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model provides a kind of transformer fence, it can adapt to the fence installation of rugged bottom by the connection of the ball cavity on the connecting sleeve and the connecting ball on the connecting rod.

[0004] The technical scheme of the utility model is as follows:

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0015] like Figure 1 As shown, a transformer fence includes support rods 10 and connecting rods 20. The number of support rods 10 is an even number (four or more), used to surround the transformer. At least two connecting sleeves 30 are rotatably mounted on each support rod 10, arranged along the height direction. Connecting sleeves 30 at the same height on adjacent support rods 10 are connected by connecting rods 20. Connecting balls 21 are provided at both ends of the connecting rods 20. Each connecting sleeve 30 has a cavity for limiting the movement of the connecting balls 21, allowing the connecting balls 21 to rotate within the limited range of the cavity. The fence of this application connects the support rods 10 via connecting rods 20, thus forming a fence surrounding the transformer. The connecting sleeves 30 can rotate axially on the support rods 10, allowing adjacent support rods 10 to be placed at any angle. The support rod 10 and the connecting rod 20 are movably connected by a ball cavity and a connecting ball 21. The connecting rod 20 can rotate relative to the ball cavity within a certain conical space, so that the positional relationship of the two connected sleeves 30 is not unique. When the fence is installed, the support rod 10 is located on the bottom surface at different heights, or the connecting sleeve 30 does not rotate into place, which does not affect the connection of the connecting rod 20. It has a more flexible connection angle, adapts to complex bottom surfaces, and the overall structure is easy to transport and assemble.

[0016] Furthermore, the support rod 10 and the connecting rod 20 can be made of materials such as PVC plastic steel, zinc steel or fiberglass.

[0017] Further, the support rod 10 is provided with a support foot below, the support angle area is greater than the area of the support rod 10, and better support effect is achieved.

[0018] As shown in Figures 2-4 The connecting sleeve 30 comprises a rotating drum 31, a lower limiting piece 32 and an upper limiting piece 33. The rotating drum 31 is rotatably arranged on the support rod 10. The lower limiting piece 32 is arranged on the rotating drum 31, and a lower limiting opening 321 is formed in the lower limiting piece 32. The upper limiting piece 33 is detachably connected with the lower limiting piece 32. An upper limiting opening 331 is formed in the upper limiting piece 33. The lower limiting opening 321 and the upper limiting opening 331 are combined to form a ball cavity for limiting the connecting ball 21. The rotating drum 31 can be rotatably connected with the support rod 10 through a bearing or a cylindrical structure. The lower limiting piece 32 is integrally designed with the rotating drum 31, and the upper limiting piece 33 is separately designed with the lower limiting piece 32. After the connecting ball 21 is placed in the lower limiting opening 321, the upper limiting piece 33 is covered to limit the connecting ball 21. Before assembly, lubricating oil can be added in the ball cavity to facilitate the rotation of the connecting ball 21.

[0019] A threaded hole 322 is formed in the lower limiting piece 32, and a through hole 332 corresponding to the threaded hole 322 is formed in the upper limiting piece 33. The through hole 332 is used for the bolt to pass through and be fixed with the threaded hole 322, so as to fix the upper limiting piece 33 and the lower limiting piece 32. Specifically, the threaded hole 322 is at least provided with two threaded holes, which are located on both sides of the lower limiting opening 321, so as to achieve better fixing effect. Further, the threaded hole 322 can also be formed in the upper limiting piece 33. In this way, the butterfly bolt can be pre-installed on the upper limiting piece 33, so that the upper limiting piece 33 and the lower limiting piece 32 can be fixed without tools. Of course, other ways of fixing the upper limiting piece 33 and the lower limiting piece 32 should also be within the protection scope of the present application.

[0020] As shown in Figure 5 The depth of the ball cavity is greater than the spherical radius and less than the spherical diameter. The depth of the ball cavity can surround the maximum cross section of the connecting ball 21, so as to limit the connecting ball 21. The upper limiting opening and the lower limiting opening 321 are respectively half of the ball cavity.

[0021] Four connecting sleeves 30 are arranged on each support rod 10. Because each support rod 10 needs to connect two adjacent support rods 10, four connecting sleeves 30 are preferably arranged to better surround the transformer. In this way, there are two connecting rods 20 with different heights on each side of the fence for surrounding the transformer, which achieves better surrounding effect and lower cost. Of course, in order to increase the surrounding effect of the fence, the number of connecting sleeves 30 on the support rod 10 can be increased to six.

[0022] Also included are the cushioning cylinders 40, which are used to be sleeved on the support rods 10, so as to adjust the height of the connecting sleeves 30. The pair of connecting sleeves 30 connected with each other need to be at the same height. In order to adjust the height and spacing of the connecting rods 20, the cushioning cylinders 40 can be increased or reduced. When more connecting sleeves 30, such as six connecting sleeves 30, are needed on the support rods 10, the cushioning cylinders 40 can be reduced or removed, so that more connecting sleeves 30 can be sleeved on the support rods 10, and after assembly, there are three connecting rods 20 on each side, and the spacing of the connecting rods 20 is smaller, which has a better enclosure effect. When there are only four connecting sleeves 30 on each side, the cushioning cylinders 40 can be increased to adjust the height of the connecting sleeves 30, so that the connecting rods 20 are located at a suitable height to enclose the transformer.

It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
