Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a portable pressure sensor. Background Art

[0002] Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electricity, ships, machine tools, pipelines and many other industries. The following is a brief introduction to some common sensor principles and their applications. Due to the wide range of uses, current pressure sensors already have the advantages of small size and portability, but it is still necessary to optimize the protection of portable pressure sensors.

[0003] For example, a portable pressure sensor is disclosed in a Chinese utility model patent with announcement number CN217276588U. In the above-mentioned prior art, although the shock-absorbing mechanism can effectively prevent the pressure sensor from being damaged by external force, and the card slot can fix the probe for easy carrying, the pressure sensor needs to be taken out from the protective shell every time it is used. Each time it is taken out, not only will it cause certain wear and tear on the fixing components inside the protective shell, but over time, the fixation will not be firm and it will be easy to shake. In addition, the protective shell needs to be put away every time it is taken out for use. Because it is portable, it is small in size and the protective shell will be lost if you are not careful. Therefore, it is necessary to design a portable pressure sensor in which the protective shell does not need to be removed during use. Utility Model Content

[0004] In order to solve the technical problem that the portable pressure sensor needs to be taken out from the inside of the protective shell every time it is used, which easily causes wear and loss of the protective shell, the utility model provides a portable pressure sensor.

[0005] The utility model is implemented by the following technical scheme: a portable pressure sensor comprises a sensor body, an outer sleeve of the sensor body is provided with a protection component for protecting the sensor body, one end of the sensor body is provided with a pushing component for pushing the sensor body out of the protection component for use, the interior of the protection component is provided with a limiting component for shock-absorbing and limiting the sensor body, and one side of the pushing component is provided with a limiting component for limiting the pushing component.

[0006] Through the above technical solution, when the pressure sensor needs to be used, the sensor body can be pushed out of the protective component for use by simply rotating the pushing component.

[0007] As a further improvement of the above scheme, the protection component includes a first protective shell mounted on the outside of the sensor body and a second protective shell fixedly installed on one side of the first protective shell, a wire threading hole is opened on one side of the first protective shell, one end of the sensor body is connected to a signal output line, and one end of the signal output line passes through the wire threading hole and enters the interior of the second protective shell.

[0008] With the above technical solution, when the sensor body is used, there is no need to take the sensor out of the protective shell.

[0009] As a further improvement of the above scheme, the pushing assembly includes a threaded rod arranged on one side of the sensor body and a pushing sleeve threadedly mounted on the threaded rod, one end of the threaded rod passes through the first protective shell and is fixedly mounted with a rotating block, one end of the pushing sleeve is fixedly mounted with two connecting strips, and one end of the sensor body is fixedly mounted with a rubber ring fixedly mounted with the two connecting strips.

[0010] Through the above technical solution, the threaded rod can be rotated to allow the push sleeve to push the sensor body out of the first protective shell for use.

[0011] As a further improvement of the above scheme, the limit assembly includes a limit ring fixedly mounted on the sensor body and sponge plates arranged on both sides of the sensor body and fixedly mounted to the inner wall of the first protective shell, and one side of the two sponge plates is provided with a sliding groove adapted to the limit ring.

[0012] Through the above technical solution, the sponge plate can not only reduce the shock of the sensor body, but also play a limiting effect when the sensor body is pushed.

[0013] As a further improvement of the above scheme, the limiting assembly includes a limiting block fixedly mounted on the inner wall of the first protective shell and having a movable groove, and a limiting bar slidably mounted inside the movable groove, and one end of the limiting bar is fixedly mounted on the pushing sleeve.

[0014] Through the above technical solution, the push sleeve will be restricted from rotating when moving, so as to avoid rotating together with the threaded rod and being unable to push the sensor body.

[0015] As a further improvement of the above scheme, a first use port is opened on the top of the first protective shell, a first cover plate is rotatably mounted on the first use port, a first magnet is fixedly mounted on one side of the first cover plate, and a second magnet fixedly mounted on the inner wall of the first protective shell is used in conjunction with one side of the first magnet; a second use port is opened on one side of the second protective shell, a second cover plate is rotatably mounted on the second use port, a third magnet is fixedly mounted on one side of the second cover plate, and a fourth magnet fixedly mounted on the inner wall of the second protective shell is used in conjunction with one side of the third magnet.

[0016] Through the above technical solution, the sensor body can be used by pushing the sensor body out of the first cover plate and then opening the second cover plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model arranges a protection component, a pushing component, a limit component and a restriction component, and places the sensor body into the protection component. When it is needed, the pushing component is used to push the sensor body out of the protection component for use. The limit component can provide shock absorption and movement limit effects for the sensor body. The restriction component prevents the pushing component from rotating to avoid the inability to push the sensor body out of the protection component for use. This arrangement can avoid the need to remove the sensor from the protection component when using the sensor, thereby avoiding the loss of the protective shell and the wear of the protection component.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A portable pressure sensor of this embodiment includes a sensor body 1. The outer sleeve of the sensor body 1 is provided with a protective component for protecting the sensor body 1. One end of the sensor body 1 is provided with a pushing component for pushing the sensor body 1 out of the protective component for use. The interior of the protective component is provided with a limiting component for shock-absorbing and limiting the sensor body 1. One side of the pushing component is provided with a limiting component for limiting the pushing component.

[0026] Combination Figure 1-Figure 3 The protection component includes a first protective shell 201 sleeved on the outside of the sensor body 1 and a second protective shell 202 fixedly installed on one side of the first protective shell 201. A threading hole is opened on one side of the first protective shell 201. One end of the sensor body 1 is connected to a signal output line 6. One end of the signal output line 6 passes through the threading hole and enters the second protective shell 202. When using the sensor body 1, there is no need to take the sensor out of the first protective shell 201.

[0027] Combination Figure 1 and Figure 3 The pushing component includes a threaded rod 301 arranged on one side of the sensor body 1 and a pushing sleeve 302 threadedly sleeved on the threaded rod 301. One end of the threaded rod 301 passes through the first protective shell 201 and is fixedly installed with a rotating block 7. One end of the pushing sleeve 302 is fixedly installed with two connecting strips 8. One end of the sensor body 1 is fixedly sleeved with a rubber ring 9 fixedly installed with the two connecting strips 8. By rotating the threaded rod 301, the pushing sleeve 302 can push the sensor body 1 out of the first protective shell 201 for use.

[0028] Combination Figure 1 and Figure 3 , combined with Figure 3 The limiting assembly includes a limiting ring 401 fixedly mounted on the sensor body 1 and sponge plates 402 arranged on both sides of the sensor body 1 and fixedly mounted on the inner wall of the first protective shell 201. One side of the two sponge plates 402 is provided with a sliding groove adapted to the limiting ring 401. The sponge plates 402 can not only reduce the shock of the sensor body 1, but also play a limiting role when the sensor body 1 is pushed.

[0029] Combination Figure 1 and Figure 3 The limiting component includes a limiting block 501 fixedly mounted on the inner wall of the first protective shell 201 and having a movable groove, and a limiting bar 502 slidably mounted inside the movable groove. One end of the limiting bar 502 is fixedly mounted on the pushing sleeve 302. The pushing sleeve 302 will be restricted from rotating when moving, so as to avoid rotating together with the threaded rod 301 and being unable to push the sensor body 1.

[0030] Combination Figure 1-Figure 3A first use port is provided at the top of the first protective shell 201, on which a first cover plate 10 is rotatably mounted, a first magnet 11 is fixedly mounted on one side of the first cover plate 10, and a second magnet 12 fixedly mounted on the inner wall of the first protective shell 201 is used in conjunction with one side of the first magnet 11; a second use port is provided at one side of the second protective shell 202, on which a second cover plate 13 is rotatably mounted, a third magnet 14 is fixedly mounted on one side of the second cover plate 13, and a fourth magnet 15 fixedly mounted on the inner wall of the second protective shell 202 is used in conjunction with one side of the third magnet 14.

[0031] The implementation principle of a portable pressure sensor in the embodiment of the present application is: when the portable sensor needs to be used, the rotating block 7 is rotated, and the threaded rod 301 will rotate together, thereby allowing the pushing sleeve 302 to move. Since the pushing sleeve 302 is connected to the limiting bar 502, it cannot rotate with the threaded rod 301, so it will be pushed by the threaded rod 301, thereby pushing the sensor body 1. When the sensor body 1 is pushed, the limit ring 401 will limit the two sponge plates 402 to prevent the sensor body 1 from moving and offset. After continuous movement, the sensor body 1 will push open the first cover plate 10, and the sensor body 1 can be used after opening the second cover plate 13. This arrangement can avoid the need to take the sensor body 1 out from the inside of the first protective shell 201 when using it.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
