Description

Technical Field

[0001] The utility model relates to the technical field of transmitter equipment, and more specifically to a pressure transmitter with a shock absorbing mechanism. Background Art

[0002] A pressure transmitter refers to a pressure sensor with a standard output signal. It is an instrument that receives pressure variables and converts them into standard output signals in proportion. It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process adjustment. At the same time, traditional transmitters are mostly installed using threaded mounting methods, and their overall seismic resistance is poor. They are unable to fully absorb and degrade external impact forces. When the transmitter is subjected to external impact and vibration, it is very easy to cause the transmitter body to fall off and be damaged.

[0003] The prior art has the following deficiencies: most conventional transmitters are installed in a threaded installation manner, and the overall anti-seismic performance is poor, and the external impact force cannot be fully absorbed and degraded, resulting in poor overall use effect. When the transmitter is subjected to external impact and vibration, it is very easy to cause the transmitter body to fall off and be damaged, thereby reducing the sealing of the connection. An existing patent discloses a pressure transmitter with anti-seismic effect, and the patent authorization number is CN 212110445 U. When the transmitter body is subjected to impact and vibration, the external impact force can be transmitted to the drive rod under the transmission of the extension plate, and the guide plate can be used to slide inside the energy absorption frame to initially absorb the impact force. At the same time, under the elastic absorption of the energy absorption spring, the guide plate can use elasticity to fully absorb the external impact force when sliding, thereby ensuring the good use state of the transmitter body, improving the overall anti-seismic effect, and improving the service life of the transmitter body.

[0004] However, the patent authorization number CN 212110445 U uses a guide plate to slide inside the energy absorption frame to initially absorb the impact force. At the same time, under the elastic absorption of the energy absorption spring, the guide plate can fully absorb the external impact force when sliding. However, directly using the energy absorption spring for buffering and energy absorption will cause the drive rod to jump up and down too much, resulting in an unsatisfactory shock absorption effect on the transmitter body. Therefore, we proposed a pressure transmitter with a shock absorption mechanism to solve the above-mentioned problems. Utility Model Content

[0030] Example:

[0031] See also Figure 1-5 , a pressure transmitter with a shock absorbing mechanism, comprising a transmitter body 1 and a pipeline 2, wherein shock absorbing mechanisms are installed on both sides of the transmitter body 1;

[0032] The shock absorbing mechanism includes a connecting plate 3 arranged at one side of the transmitter body 1 and connected to the pipeline 2, a strip hole 4 symmetrically opened on the surface of the connecting plate 3, a guide column 5 welded on the inner side of the strip hole 4, a movable seat 7 symmetrically connected to the guide column 5 for sliding movement, a guide column 8 welded to the outer walls on both sides of the movable seat 7, a guide groove 9 opened on the inner wall of the strip hole 4 and loosely matched with the guide column 8, a spring 25 symmetrically sleeved on the end of the guide column 8, a first shaft rod 10 welded above the movable seat 7 through a bracket, a connecting seat 12 arranged above the connecting plate 3, a second shaft rod 11 welded below the connecting seat 12 through a bracket, a support arm 24 rotatably connected to the first shaft rod 10 at the bottom end and rotatably connected to the second shaft rod 11 at the top end, a damping rod 13 connected to the upper surface of the connecting plate 3 at the bottom end and connected to the lower surface of the connecting seat 12 at the top end, a connecting rod 14 installed on the connecting seat 12 close to the outer wall of the transmitter body 1, and a mounting seat 15 installed at the end of the connecting rod 14 and connected to the transmitter body 1 through screws;

[0033] It should be noted that the transmitter body 1 and the pipeline 2 are first quickly connected to ensure the stability of the subsequent installation work, and the mounting seat 15 set at the end of the connecting rod 14 is connected to the transmitter body 1. When the transmitter body 1 is subjected to impact vibration, the absorbed vibration is transmitted as up and down fluctuations through the connecting seat 12, and at the same time, the two ends of the support arm 24 are respectively matched with the first shaft rod 10 and the second shaft rod 11 to rotate, so that the guide column 8 slides with the guide groove 9 to drive the movable seat 7 to slide synchronously with the guide column 5, and the spring 25 sleeved on the end of the guide column 5 is compressed and deformed to absorb vibration, and in the process of the connecting seat 12 descending, the energy transfer caused by vibration, impact or other forms of movement is reduced by contraction of the damping rod 13, thereby improving the energy absorption effect, avoiding the rebound force of the spring 25 causing the connecting seat 12 to jump up and down, and improving the shock absorption effect of the transmitter body 1.
