The technical scheme of the invention is further described in detail by the following specific embodiments in combination with the attached drawings:
example 1
As shown in fig. 1-2, an embodiment of a tool for disassembling a dial of a pressure gauge includes a fixed handle 1, a locking band 2 for locking the dial, and a movable handle 3; the fixed handle 1 is provided with a tensioning part 4 connected with one end of the locking belt 2; the movable handle 3 is connected with the fixed handle 1 through a rotating shaft, and a driving part 5 for driving the tensioning part 4 to rotate is arranged on the movable handle 3; when the movable handle 3 rotates towards the fixed handle 1, the driving part 5 drives the tensioning part 4 to pull the locking belt 2.
Specifically, the driving part 5 is a driving gear, and the center of the driving gear is positioned at the rotating shaft connection part of the movable handle 3 and the fixed handle 1; the tensioning part 4 is a driven gear which is meshed with the driving gear and is connected with the fixed handle 1 through a rotating shaft. When the movable handle 3 is pulled to rotate, the driving gear is driven to rotate, the driven gear is driven to rotate, and one end of the locking belt 2 is connected with the edge of the driven gear. When the driven gear rotates, one end of the locking belt 2 can be driven to move, and the purposes of tensioning the locking belt 2 and driving the dial plate to rotate are achieved. The driving gear is connected with movable handle 3, can all turn into the angle of the turning of driving gear with movable handle 3 to make tensioning part 4 have corresponding motion, all convert staff's work into the power of driving gear, further reduce staff's work output.
In the present embodiment, the number of teeth of the driven gear is greater than that of the driven gear, and the gear ratio of the driving gear to the driven gear is 1: 4. The number of teeth of the driven gear is more, the diameter is larger, and when the driving gear drives the driven gear to rotate, the driven gear can rotate more girth distances than the driving gear, so that the motion amplitude of the locking belt 2 is larger, and the strength is stronger.
Specifically, the tail end of the fixed handle 1 is provided with a fixed belt 6 for fixing the pressure gauge. When carrying out the dismouting, the surface of the winding manometer body of fixed band 6 fixes the manometer body through fixed band 6, then as long as keep fixed handle 1 motionless, the manometer body just can not remove, avoids when dismantling the dial plate, and the manometer body is along with the dial plate motion to make the dial plate dismantle more easily.
Wherein, the fixing belt 6 is a canvas belt. The canvas belt has good toughness and is not easy to break after being pulled.
In addition, one end of the fixed handle 1 close to the fixed belt 6 is provided with a pressing part 7 used for being abutted against a pressure gauge. The winding of fixed band 6 is behind the manometer body, and the portion of compressing tightly 7 compresses tightly on fixed band 6, indirect and manometer surface butt to compress tightly fixed band 6. The fixed handle 1 can also be forced on the pressure gauge body through the pressing part 7, so that when the fixed handle 1 is held by hands, the position of the fixed handle 1 is more stable.
The working principle or working process of the invention is as follows: as shown in fig. 3, the locking band 2 is wound around the side wall of the dial plate of the pressure gauge 9 for at least two turns, so that the locking band 2 is in a stretched state. Certain contained angle and distance are formed between the initial position of activity handle 3 and fixed handle 1, and pulling activity handle 3 rotates to fixed handle 1's direction for drive division 5 drive tensioning portion 4 further makes locking band 2 taut, thereby makes locking band 2 pull dial plate to certain direction rotation break away from the manometer. The staff can operate two handles with one hand to draw the two handles close.
The beneficial effects of this embodiment: the movable handle 3 drives the tensioning part 4 to move through the driving part 5, so that the locking belt 2 connected with the tensioning part 4 drives the dial plate to rotate, the dial plate is separated from the pressure gauge, the worker pulls the movable handle 3 to enable the dial plate and the pressure gauge to move relatively in a labor-saving manner, and the labor intensity of the worker who needs to output when the dial plate is detached is reduced.
Example 2
As shown in fig. 1-2, another embodiment of the present invention is different from embodiment 1 in that the locking band 2 is an elastic belt, which has good elasticity, and when the tensioning portion 4 pulls the elastic belt to tension, the elastic belt itself has the characteristic of springback, that is, one end of the locking band 2 contacting with the dial plate drives the dial plate and the pressure gauge body to move relatively due to springback. Therefore the staff takes 2 pulling dial plate pivoted effort cooperation locking band 2's resilience characteristic through the locking, makes the dial plate rotate for the manometer body more easily to pull down the dial plate more easily.
In addition, the fixed handle 1 and the movable handle 3 are both provided with anti-skid rubber sleeves 8; the antiskid rubber sleeve 7 is provided with antiskid lines. The anti-slip rubber sleeve 8 and the anti-slip pattern can avoid the problem that the handle slips when a worker holds the handle.
The remaining features and operating principle of this embodiment are consistent with embodiment 1.
