[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] See also Figure 1-6 As shown, a dry-type transformer withstand voltage tester comprises a tester body 1, on which a support mechanism 2 is installed, wherein the support mechanism 2 comprises a connecting block 201, two connecting blocks 201 are installed at both ends of the bottom of the tester body 1, a fixed shaft 206 is fixedly connected between the two connecting blocks 201, symmetrical support plates 202 are installed at both ends of the bottom of the tester body 1, the top of the support plate 202 is rotatably connected to the fixed shaft 206, a gear 205 is fixedly connected at the center of the fixed shaft 206, the gear 205 is rotatably connected to the inner side of the top of the support plate 202, a locking pin 207 is installed on the inner side of the top of the support plate 202, the locking pin 207 is slidably connected to the inside of the support plate 202 through a resisting spring 208, and the top of the locking pin 207 extends to the outside of the support plate 202 and resists the gear 205.

[0025] As a technical optimization solution of the utility model, the bottom of the two support plates 202 are respectively connected with rubber blocks 210, and the cross-section of the rubber block 210 is a "convex" shaped structure. The installation of the rubber block 210 is beneficial to supporting and protecting the bottom of the support plate 202, and plays an insulating role, while facilitating subsequent disassembly and replacement.

[0026] As a technical optimization scheme of the utility model, two locking grooves 213 are provided at the center line of the bottom of the detector body 1, and the bottom side of the two support plates 202 is rotatably connected with a rotating shaft 204, and the rotating shaft 204 extends to the outside of the support plate 202. A card block 203 is installed on the rotating shaft 204. The card block 203 is an elliptical structure. The installation of the rotating shaft 204 is conducive to the drive control of the card block 203. After the support plate 202 is rotated to fit with the bottom plate of the detector body 1, the card block 203 is inserted into the locking groove 213. By rotating the card block 203, the card block 203 is locked with the inside of the locking groove 213, so that the support plate 202 is closed and stable and will not loosen.

[0027] As a technical optimization solution of the utility model, a driving rod 209 is slidably connected inside the support plate 202, and a movable groove 211 is provided on the rotating shaft 204. One end of the driving rod 209 passes through the resistance spring 208 and is connected with the locking pin 207, and the other end of the driving rod 209 extends into the movable groove 211. The opening of the movable groove 211 facilitates the driving rod 209 to slide inside the support plate 202, so that the locking pin 207 can move freely. By rotating the rotating shaft 204 to a certain position, the movable groove 211 and the driving rod 209 are not on the same horizontal line, which facilitates the locking pin 207 to not loosen, and plays a role in resisting and locking the gear 205, so that the support plate 202 cannot rotate.

[0028] As a technical optimization solution of the utility model, a groove 212 is provided on one side of the rotating shaft 204, and the groove 212 is located on the back side of the movable groove 211. The depth of the groove 212 is less than the depth of the movable groove 211. One end of the driving rod 209 is an arc structure, and the rotating shaft 204 rotates to contact the driving rod 209. Under the action of the groove 212, after the rotating shaft 204 rotates to a certain position, the driving rod 209 contacts the groove 212 to play a positioning role.

[0029] As a technical optimization solution of the utility model, a protective mechanism 3 is installed on the detector body 1, and the protective mechanism 3 includes a baffle 301. A baffle 301 is installed on the top of the detector body 1, and one end of the baffle 301 extends to the outside of one side of the detector body 1. The installation of the baffle 301 is conducive to shielding one side of the detector body 1, thereby providing shade and facilitating viewing and operation.

[0030] As a technical optimization solution of the utility model, a storage groove 302 is provided on the top of the detector body 1, and one end of the baffle 301 is rotatably connected to the inside of the storage groove 302. One side of the storage groove 302 is an arc-shaped structure, which is conducive to the baffle 301 being able to rotate, store and store inside the storage groove 302. At the same time, the baffle 301 can well shield the detector body 1 after being opened.

[0031] As a technical optimization scheme of the utility model, a mounting base 303 is installed on the top of the detector body 1, and a handle 304 is rotatably connected inside the mounting base 303. One side of the handle 304 extends to the outside of the mounting base 303. The installation of the mounting base 303 is conducive to the installation of the handle 304, and the rotation of the handle 304 and the mounting base 303 facilitates the storage of the handle 304, and also facilitates the lifting and moving of the detector body 1 after the handle 304 is rotated and opened.

[0032] As a technical optimization solution of the utility model, a rubber pad 306 is installed on one side of the mounting seat 303, and one side of the handle 304 contacts the rubber pad 306. The installation of the rubber pad 306 is conducive to contacting the handle 304, so that the handle 304 will not rotate at will.

[0033] As a technical optimization solution of the utility model, multiple columns 307 are installed on one side of the detector body 1, and a buckle 305 is rotatably connected to the column 307. A protective pad 308 is installed on the buckle 305. The buckle 305 can be easily rotatably installed under the action of the column 307, which is beneficial to the first engagement and guidance of the detector body 1 to prevent looseness from affecting the detection effect. The protective pad 308 can also prevent the cable from being worn.

[0034] When the utility model is in use, first, by rotating the handle 304, the handle 304 is perpendicular to the mounting seat 303, which is convenient for holding and moving the detector body 1. After the detector body 1 is moved to the specified position, the drive shaft is rotated to separate the latch pin from the inside of the latch slot, which is convenient for rotating and opening the two support plates 202, thereby supporting the detector body 1. When the support plate 202 rotates, the lock pin 207 and the gear 205 are moved in contact with each other, which is convenient for adjusting the rotation angle of the support plate 202, thereby adjusting the support angle according to the on-site terrain. After the support is stable, the rotating shaft 204 is rotated, and the rotating shaft 204 contacts the driving rod 209, and the lock pin 207 cannot move, so that the support plate 202 is limited and supported stably. Then, under the action of the buckle 305, it is convenient to guide the cable engagement, thereby facilitating the detection work connected to the transformer, preventing the cable from being loosened due to disorderly pulling and affecting the detection effect, and finally, by rotating the baffle plate 301, the baffle plate 301 blocks the operating side of the detector body 1, which is convenient for the staff to watch.
