Detailed Description

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses a voltage monitor.

Referring to fig. 1, the voltage monitor includes a monitor body 1 and an adjustment foot 2. Adjust stabilizer blade 2 setting in monitor body 1's bottom, and adjust stabilizer blade 2 interval and be provided with a plurality ofly, and then still can make monitor body 1 more steady place on the uneven brace table of holding surface through adjusting the length that corresponds adjusting stabilizer blade 2 when supporting monitor body 1.

In this embodiment, the bottom of the monitor body 1 is preferably a rectangular plane, the four adjusting legs 2 are preferably arranged, and the four adjusting legs 2 are respectively located at four right angles of the bottom of the monitor body 1. The four adjusting feet 2 are identical in construction and will be described below by taking one adjusting foot 2 as an example.

Referring to fig. 1 and 2, the adjustment foot 2 includes a fixing sleeve 21, a support post 22, a tightening cam 23, and an adjustment spring 24. The fixed sleeve 21 and the shell of the monitor body 1 are integrally formed, and the support column 22 is slidably arranged in the fixed sleeve 21. The tightening cam 23 is rotatably mounted on the fixing sleeve 21 to limit the sliding support column 22, so as to adjust the length of the support column 22 protruding from the fixing sleeve 21. The adjusting spring 24 drives the support column 22 to automatically abut against the support table when the support column is not limited by the fastening cam 23.

The outer wall of the support column 22 is integrally formed with a limiting block 221, and the limiting block 221 is positioned on one side close to the monitor body 1. A limit groove 211 is formed in one side, away from the monitor body 1, of the fixed sleeve 21, and the limit groove 211 is communicated with the inside of the fixed sleeve 21. When the support column 22 slides in the fixing sleeve 21, the limiting block 221 is inserted into the limiting groove 211 and slides in the limiting groove 211. The blocking block 212 is inserted in the notch of the limiting groove 211 in an interference manner, so that the limiting block 221 is limited in the limiting groove 211, and the supporting column 22 is not easy to deviate from the fixed sleeve 21 in the sliding process.

Referring to fig. 1 and 2, a support plate 222 is integrally formed with an end of the support column 22 facing away from the fixing sleeve 21. In this embodiment, the support column 22 is a cylinder, the support plate 222 is a circular plate, the central axis of the support column 22 coincides with the central axis of the support plate 222, and the outer diameter of the support plate 222 is larger than the outer diameter of the support column 22, so that the monitor body 1 is more stable after being placed.

One end of the support column 22, which is away from the support plate 222, is integrally formed with a sleeved column 223, and the adjusting spring 24 is partially sleeved on the sleeved column 223. When the support column 22 is inserted into the fixed sleeve 21, one end of the adjusting spring 24 is abutted against the support column 22, and the other end is abutted against the bottom of the monitor body 1. And further, the support plate 222 automatically abuts against the support table under the drive of the adjusting spring 24 after the tightening cam 23 is released.

The outer wall of the fixed sleeve 21 is integrally formed with rotating lugs 213, the rotating lugs 213 are located on one side of the fixed sleeve 21, which faces away from the monitor body 1, and two rotating lugs 213 are arranged at intervals along the circumferential direction of the fixed sleeve 21. The fastening cam 23 is located between the two rotation lugs 213, and the fastening cam 23 is rotatably mounted on the rotation lugs 213 by a rotation pin. The outer wall of the fixed sleeve 21 is also provided with a fastening hole 214 for the fastening cam 23 to hang into the fixed sleeve 21 after rotating, and the fastening hole 214 is positioned between the two rotating lugs 213. The rotating part of the fastening cam 23 is positioned inside the fixing sleeve 21 and abuts against the side wall of the support column 22.

Referring to fig. 1 and 2, a lever 231 is integrally formed with an outer wall of the tightening cam 23. In the process that the support column 22 is tightly limited in the solid sleeve by the rotation of the tight-fixing cam 23, one end of the deflector rod 231 deviating from the tight-fixing cam 23 rotates towards the direction close to the monitor body 1, so that the deflector rod 231 is not easy to interfere with the support plate 222. When the tightening cam 23 abuts against the support column 22, the shift lever 231 abuts against the outer wall of the fixing sleeve 21, and further the rotation of the tightening cam 23 is limited.

A through hole 2311 is formed in one side of the deflector rod 231 facing away from the fastening cam 23, and a pull ring 232 is penetrated into the through hole 2311. When the tightening cam 23 is released, a finger can be inserted into the pull ring 232 to pull the deflector 231 to drive the tightening cam 23 to rotate, so that the limit of the tightening cam 23 to the support column 22 is relieved.

The implementation principle of the voltage monitor in the embodiment of the application is as follows: when the monitor body 1 is placed on the supporting table through the adjusting support legs 2, if the plane of the supporting table is uneven, the pull ring 232 on the corresponding adjusting support legs 2 can be pulled, so that the tightening cam 23 can rotate without limiting the supporting column 22. The support column 22 automatically abuts against the surface of the support table under the action of the adjusting spring 24, and then the driving lever 231 is rotated to drive the fastening cam 23 to rotate towards the inside of the fixed sleeve 21 and abut against the outer wall of the support column 22 to limit the support column 22.

The support column 22 is abutted and limited by the rotation of the fastening cam 23, so that the length of the support column 22 protruding out of the fixing sleeve 21 can be adjusted at will.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
