Embodiment 1

[0024] Such as Figure 1-2 Shown is an embodiment of a tool for removing the dial of a pressure gauge, including a fixed handle 1, a locking band 2 for locking the dial, and a movable handle 3; Part 4; the movable handle 3 is connected with the fixed handle 1 shaft, and the movable handle 3 is provided with a drive part 5 that drives the tension part 4 to rotate; when the movable handle 3 rotates to the fixed handle 1, the drive part 5 drives the tension part 4 Pull the locking strap 2.

[0025] Specifically, the driving part 5 is a driving gear, and the center of the driving gear is located at the joint between the movable handle 3 and the fixed handle 1; When the movable handle 3 is pulled to rotate, the driving gear is rotated, the driven gear is driven to rotate, and one end of the locking band 2 is connected with the edge of the driven gear. When the passive gear rotates, it will drive one end of the locking belt 2 to move, so as to achieve the purpose of making the loc...

Embodiment 2

[0033] Such as Figure 1-2 Shown is another embodiment of the present invention. The difference from Embodiment 1 is that the locking belt 2 is an elastic belt with good elasticity. When the tensioning part 4 pulls the elastic belt to tighten, the elastic belt itself has a back The characteristics of the spring, that is, the end of the locking band 2 in contact with the dial will drive the dial and the pressure gauge body to move relative to each other due to the rebound. Therefore, the working force of the staff to pull the dial to rotate through the locking band 2 cooperates with the rebound characteristics of the locking band 2, making it easier for the dial to rotate relative to the pressure gauge body, thereby making it easier to remove the dial.

[0034] In addition, both the fixed handle 1 and the movable handle 3 are provided with anti-slip rubber sleeves 8; the anti-slip rubber sleeves 7 are both provided with anti-slip patterns. The effect of the anti-slip rubber slee...

Abstract

The invention relates to a tool for dismantling the dial of a pressure gauge, which comprises a fixed handle, a locking band for locking the dial and a movable handle; the fixed handle is provided with a tensioning part connected to one end of the locking band; connection, the movable handle is provided with a driving part that drives the tension part to rotate; when the movable handle rotates toward the fixed handle, the driving part drives the tension part to pull the locking belt. The movable handle drives the tensioning part to move through the driving part, so that the locking belt connected with the tensioning part drives the dial to rotate, so that the dial is separated from the pressure gauge, and the staff can pull the movable handle to make the gap between the dial and the pressure gauge more labor-saving. Relative movement occurs, thereby reducing the labor intensity that the staff needs to output when disassembling the dial.

Description

technical field [0001] The invention relates to the field of tools for removing and assembling dials, and more particularly relates to a tool for removing dials of pressure gauges. Background technique [0002] There are many SF6 pressure gauges such as circuit breakers and transformers in the substation. The harsh outdoor conditions of wind and sun can easily cause the pressure gauge to be blurred, which will affect the readings of the inspectors and even cause defects that cannot be read. Due to the high value of the pressure gauge, Replacing the entire meter just because the dial is blurred is expensive and will cause huge waste. At the same time, due to the riveted structure connection between the meter and the equipment, it is difficult to disassemble and replace the entire meter. [0003] The publication number is "CN203918927U", and the Chinese patent with the publication date of November 5, 2014 discloses a device for installing and dismounting the dial of a pressure...
