Technical Field

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

[0002] At present, pressure sensors, as a device or apparatus that can convert pressure signals into electrical signals, have been widely used in industrial practice. Pressure sensors are usually composed of pressure sensitive elements and signal processing units, which can sense pressure signals and convert them into usable electrical signal outputs according to certain rules. This enables pressure sensors to assist machines in making judgments and play an important role in various industrial automatic control environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipelines and many other industries.

[0003] On the other hand, as a type of weighing instrument, the development history of electronic scales reflects the continuous innovation of weighing technology.

[0026] Most pressure sensors are fixed to a fixing frame by multiple bolts, which is not only troublesome to install, but also restricted by the fixing frame, which reduces the work efficiency of pressure sensor installation and wastes time. It also requires excessive physical strength, thus reducing the practicality of the fixing device.

[0027] See also Figure 1-Figure 4 The embodiment of the utility model shown in the figure comprises a base frame 10, a fixing frame 11 and a pressure sensor body 12, both ends of the pressure sensor body 12 are provided with limiting holes 121, and two fixing members 20 for mounting the pressure sensor body 12 are arranged in the middle of the base frame 10 and the fixing frame 11, wherein: the fixing member 20 comprises at least a mounting plate 21, a limiting shaft 24 for plugging and fitting with the limiting hole 121 is arranged in the middle of the mounting plate 21 close to the pressure sensor body 12, a clamping assembly 23 for mounting the pressure sensor body 12 is arranged on the side of the mounting plate 21 close to the pressure sensor body 12, and an auxiliary assembly 22 for assisting the pressure sensor body 12 to be installed inside the clamping assembly 23 is arranged on one side of the mounting plate 21.

[0028] First, the specific structure of the auxiliary component 22 is disclosed. The auxiliary component 22 at least includes a telescopic rod 221. The telescopic rod 221 is arranged in the middle of one side of the mounting plate 21, and the piston rod of the telescopic rod 221 is provided with an auxiliary rod 222.

[0029] The improvement lies in that: by pushing the auxiliary rod 222, the telescopic rod 221 is retracted and the clamping assembly 23 is opened, thereby assisting the pressure sensor body 12 in the installation work. Similarly, by pulling the auxiliary rod 222, the telescopic rod 221 is lengthened, so that the clamping assembly 23 can be clamped, thereby improving the work efficiency of the installation of the pressure sensor body 12, avoiding wasting time, and also improving the practicality of the fixing device, thereby improving the flexibility of the fixing device.

[0030] Secondly, the specific structure of the clamping assembly 23 is disclosed. The clamping assembly 23 at least includes a movable groove 231. The movable grooves 231 are opened on both sides of one side of the mounting plate 21, and elastic members 232 are arranged on both sides inside the mounting plate 21. The elastic member 232 extends to one end of the movable groove 231 and a clamping plate 233 is arranged.

[0031] The improvement lies in that the auxiliary rod 222 is pushed between the two clamping plates 233. At this time, the elastic member 232 is deformed and elongated, and the two clamping plates 233 are moved away from each other, so that the mounting plate 21 can be clamped on the pressure sensor body 12. Then the auxiliary rod 222 is pulled out, and the two clamping plates 233 are moved closer to the pressure sensor body 12 and clamped by the rebound force of the elastic member 232. This not only makes the operation simple, but also improves the work efficiency of the installation of the pressure sensor body 12 and avoids wasting time. It also improves the stability of the installation of the pressure sensor body 12 and avoids damage to the pressure sensor body 12, thereby improving the practicability of the fixing device.

[0032] The auxiliary rod 222 is used to support the clamping plates 233 on both sides. However, inserting the auxiliary rod 222 between the two clamping plates 233 may easily cause the user to be injured and reduce the efficiency of the pressure sensor installation. Therefore, the two ends of the auxiliary rod 222 are arc-shaped.

[0033] The improvement lies in that: through the arcs at both ends of the auxiliary rod 222, the auxiliary rod 222 can be quickly moved between the two clamps 233, which will prevent pinching when installing the pressure sensor body 12, improve the work efficiency of the installation of the pressure sensor body 12, avoid wasting time, and thus improve the practicality of the fixing device.

[0034] Since the pressure sensor body 12 may be damaged or the installation stability of the pressure sensor body 12 may be reduced when the clamp 233 clamps the pressure sensor body 12 through the rebound force of the elastic member 232, an anti-slip pad 25 is provided on the side of the clamp 233 close to the elastic member 232 and the outer wall of the limit shaft 24.

[0035] The improvement lies in that: by providing an anti-slip pad 25, not only can the damage caused by the clamping plate 233 to the pressure sensor body 12 be avoided, but also the stability of the installation of the pressure sensor body 12 is increased, the protective effect of the pressure sensor body 12 is improved, and the practicality of the fixing device is increased, thereby improving the safety of the use of the electronic scale.

[0036] In summary, the working principle of the present scheme is as follows: first, the telescopic rod 221 is contracted by pushing the auxiliary rod 222, and is pushed between the two clamps 233 by the auxiliary rod 222. At this time, the elastic member 232 is deformed and elongated, and the two clamps 233 are moved away from each other, so that the mounting plate 21 can be clamped on the pressure sensor body 12. At the same time, the limiting shaft 24 is inserted into the limiting hole 121, and then the auxiliary rod 222 is pulled out. Through the rebound force of the elastic member 232, the two clamps 233 are moved closer to the pressure sensor body 12 and clamped, thereby completing the installation of the pressure sensor body 12 by the fixing device.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
