Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention is a spring type pressure gauge for an inflator, comprising an outer housing 1, a dial 2 is mounted on the outer housing 1, and scale marks are provided on the dial 2, more importantly, a pressure tapping pipe 3 is mounted on one side of the outer housing 1, the pressure tapping pipe 3 is connected to an external pressure collecting pipe, so that a connecting device matching with the external pressure collecting pipe can be disposed on the upper portion of the pressure tapping pipe, a bearing plate 4 is mounted on the end of the pressure tapping pipe 3, the bearing plate 4 is mounted on the inner wall of the pressure tapping pipe 3 in a sealing manner, and the rear portion of the bearing plate 4 is abutted against one end of a first spring 5, so that the bearing plate 4 can push the first spring 5 to compress under the action of external pressure, and the other end of the first spring 5 is abutted against a sealing ring 6, the sealing ring 6 is connected with a straight tooth 7, the straight tooth 7 is meshed with a circular tooth 8, a pointer 9 is arranged on the circular tooth 8, so that a linkage structure is formed, and the indicating end of the pointer 9 needs to be arranged on the dial 2; it is worth noting that, in order to improve the accuracy of the pressure gauge, a calibration structure is further designed, specifically, one end of the straight tooth 7, which is far away from the sealing ring 6, abuts against one end of the second spring 10, the other end of the second spring 10 abuts against the calibration spring push plate 11, then the calibration spring push plate 11 is in power connection with the calibration screw 12, and finally the calibration screw 12 is arranged on the other side of the outer shell 1. Preferably, the outer contour of the outer shell 1 can be designed to be cylindrical, and the first spring 5, the sealing ring 6, the straight teeth 7, the round teeth 8, the second spring 10 and the calibration spring push plate 11 are all arranged inside the cylindrical outer shell 1, so that the integrity of a pressure gauge product is increased while the structure of the pressure gauge is simplified, and the structure of the pressure gauge is more compact; in cooperation with this, the dial 2 may be designed to be in an arc shape matching with the outer case 1.
In this embodiment, through set up pressure tube body 3 in one side of shell 1, by the inside terminal bearing plate 4 of gaseous promotion pressure tube body 3, bearing plate 4 promotes sealing washer 6 when atmospheric pressure is greater than the elasticity of first spring 5, and then drive the rotation of circular tooth 8 through straight-tooth 7 of power connection with it, make the pointer 9 of installation on the 8 axle centers of circular tooth rotate, make the tip of pointer 9 form the instruction scale on dial 2, and also can adjust the position of calibration spring push pedal 11 through calibration screw 12, make second spring 10 compressed to different degrees, with this accuracy that promotes pointer 9 and instruct.
Referring to fig. 1 again, in another embodiment of the present invention, the inventor makes a little improvement on the structure of the above embodiment in order to improve the calibration stability of the pressure gauge, specifically adds a spring seat 13, and the spring seat 13 is linked with or directly fixedly connected with the straight tooth, so that the straight tooth 7 can be abutted against the second spring 10 through the spring seat 13, and then the second spring 10 can be sleeved on the rear end of the spring seat 13, so that the second spring is compressed under the action of the calibration spring push plate 11, and the accuracy is higher and remains stable. Further, based on the same idea, in this embodiment, in order to ensure the stability of the first spring 5 when being compressed, an extension section 61 may be additionally arranged at the front end of the sealing ring 6, and then the first spring 5 is sleeved on the extension section 61, so as to ensure that the first spring 5 can be always kept stable when being compressed under the action of the pressure-bearing plate 4, thereby ensuring the accuracy of the indication scale of the pointer 9.
On the other hand, in normal conditions, the adjustable space of the pressure gauge is generally larger than the maximum indication range of the pointer 9, so that the overall axial length of the second spring 10 is larger than the axial length of the first spring 5; and in order to facilitate the fixing of the adjusting screw 12 on the outer casing 1, an internal threaded hole matched with the calibrating screw 12 can be arranged on the other side of the outer casing 1.
Referring to fig. 1, in practical use, in general, a pressure gauge is installed in the inflator for detecting the current pressure of the inflator, when the pressure gauge is used, one path of the detection pipeline of the inflator is communicated with the pressure taking pipe 3, when gas enters the pressure taking pipe 3 through the detection pipeline, since the pressure bearing plate 4 is hermetically installed inside the pressure taking pipe 3, the gas pressure pushes the pressure bearing plate 4 to move backward, if the current gas pressure is greater than the elastic force of the first spring 5, the first spring 5 is compressed, and the sealing ring 6 is pushed to move backward, so as to drive the straight teeth 7 to move backward, and finally drive the circular teeth 8 to rotate, so that the pointer 9 rotates, and at this time, the indication end of the pointer 9 points to the corresponding position on the dial 2, and displays the current gas pressure value, which is in units of Pa or Mpa, when the gas pressure decreases or disappears, the pressure bearing plate 4 in the pressure taking pipe body 3 is reset under the action of the first spring 5, the straight teeth 7 are also reset to the initial state, and the pointer 9 on the circular teeth 8 returns to the zero position at the moment; in the use process of the pressure gauge, the calibration screw 12 can be adjusted, the second spring 10 is pushed to different compression degrees by the calibration spring push plate 11, and the second spring 10 abuts against the straight tooth 7 through the spring seat 13, so that the initial position of meshing of the straight tooth 7 and the circular tooth 8 can be calibrated, and the pointer 9 on the circular tooth 8 is kept at the zero position of the dial 2 in a pressure-free state, so that the use accuracy of the pressure gauge is ensured.
