Technical Field

[0001] The utility model relates to the technical field of inlet pressure heads, and particularly relates to an inlet pressure head for a sensor. Background Art

[0002] A sensor is a device used for pressure sensing and monitoring functions. When installing the sensor, it needs to be installed to ensure the stability of the sensor during operation and also avoid damage to the sensor.

[0003] The existing sensor installation method usually uses a threaded rod to fix the sensor. Although this method can fix the sensor, after the existing pipelines are installed, some pipelines are close to the wall. Therefore, during the installation process, it is not convenient for the user to rotate the threaded rod on the sensor, so the sensor cannot be normally installed due to the obstruction of the wall, which reduces the use range and practicability of the sensor. For this reason, we propose an inlet pressure head for a sensor. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a pressure inlet head for a sensor, including a docking shell 1. A square groove 3 is opened at the top of the docking shell 1. A placement groove 6 is opened at the bottom of the inner wall of the square groove 3. A positioning block 7 is sleeved on the inner wall of the placement groove 6. A receiving groove 5 is opened at the top of the positioning block 7. A body 2 is fixedly assembled at the top of the positioning block 7. An installation groove 8 is opened in the middle of the positioning block 7. A snap spring 12 is sleeved on the inner wall of the installation groove 8. The top end of the snap spring 12 abuts against a second snap pin 9. A snap rod 10 is fixedly assembled at the top of the second snap pin 9. An activity groove 11 is opened in the middle of the docking shell 1. A first snap pin 4 is slidably connected to the inner wall of the activity groove 11.

[0021] In the above structure, through the structures of the docking shell 1, the body 2, the square groove 3, the first snap pin 4, the receiving groove 5, and the placement groove 6, when the user installs the sensor, there is no need to install it by means of threaded connection. The user only needs to align the limiting block with the square groove 3, and then push the body 2 downward to connect the positioning block 7 with the docking shell 1, so as to achieve the effect of quickly docking the body 2, and then facilitate the user to install it, improving the installation efficiency of the user for the body 2.

[0022] In a preferred embodiment: the bottom of the first snap pin 4 abuts against the top of the snap rod 10. The number of snap rods 10 is two, and the bottom of one snap rod 10 abuts against the top of the other snap rod 10.

[0023] In the above structure, through the structures of the first snap pin 4 and the two snap rods 10, when the user needs to disassemble and assemble the body 2, the user can press the snap rod 10 to make it move downward, so that the snap rod 10 is inserted into the inner wall of the receiving groove 5, ensuring that the user can continuously rotate the positioning block 7 after the positioning block 7 is inserted into the placement groove 6, so as to fix the positioning block 7, and then ensure the stability of the body 2 after installation, achieving the effect of quick fixation.

[0024] In a preferred embodiment: the number of receiving grooves 5 is two. The depth of one receiving groove 5 is 1 cm, and the depth of the other receiving groove 5 is 2 cm. The diameters of the two receiving grooves 5 are all adapted to the diameter of the snap rod 10.

[0025] In the above structure, through the two storage grooves 5 provided, the two clamping rods 10 can be made to be on the same horizontal plane as the top of the positioning block 7 by using the moving space provided by the two storage grooves 5, so as to ensure that the user can rotate the positioning block 7 to misalign the clamping rod 10 with the square groove 3, and then the clamping rod 10 is used to fix between the docking shell 1 and the positioning block 7, ensuring the stability of the body 2 after installation.

[0026] In a preferred embodiment: The positioning block 7 is fixedly connected to the docking shell 1 through the second pin 9, and a limiting block is fixedly assembled on the outer wall of the positioning block 7, and the diameter of the limiting block is adapted to the diameter of the square groove 3.

[0027] In the above structure, through the provided limiting block structure, when the user aligns the limiting block with the square groove 3 again, the positioning block 7 and the limiting block can move into the docking shell 1, so that the limiting block can slide along the inner wall of the square groove 3. When the bottom of the positioning block 7 contacts the bottom of the inner wall of the placement groove 6, the user can rotate the positioning block 7 to misalign the limiting block with the square groove 3, so that the body 2 is restricted from detaching from the docking shell 1, and cooperate with the clamping rod 10 to fix it, thereby improving the installation efficiency of the user for the body 2.

[0028] In a preferred embodiment: A through hole is provided at the top of the inner wall of the installation groove 8, and the outer wall of the second pin 9 is slidably connected to the inner wall of the through hole.

[0029] In the above structure, through the provided through hole and second pin 9 structure, when the user continuously rotates the positioning block 7, the elastic force of the clamping spring 12 is used to make the second pin 9 pass through the through hole and connect with the docking shell 1, so that the clamping rod 10 abuts against the strip groove and the body 2 is fixed, thereby achieving the effect of quickly fixing the body 2, which is convenient for the user to operate.

[0030] In a preferred embodiment: The second pin 9, the clamping rod 10 and the first pin 4 are all made of galvanized iron metal. A strip groove is provided at the top of the inner wall of the placement groove 6, and the diameter of the strip groove is adapted to the diameter of the clamping rod 10.

[0031] In the above structure, galvanized iron metal has the characteristics of hardness and wear resistance, which can reduce the wear degree when fixing the body 2 and the positioning block 7. At the same time, the hardness characteristics of galvanized iron metal can ensure the fixing effect on the positioning block 7, extending the service life of the three. Moreover, galvanized iron metal also has the characteristic of low cost, reducing the production cost and maintenance cost of this pressing head.

[0032] Working principle: First, when the user installs the main body 2, the limiting block provided on the outer wall of the positioning block 7 can be aligned with the square groove 3, and then the main body 2 is pushed so that the limiting block slides along the inner wall of the square groove 3. When the bottom of the positioning block 7 abuts against the bottom of the inner wall of the placing groove 6, the clamping rod 10 is pressed so that the clamping rod 10 is on the same horizontal plane as the top of the positioning block 7. Then the positioning block 7 is rotated. At this time, the top of the inner wall of the placing groove 6 will limit the clamping rod 10, so that the clamping rod 10 cannot pop out. The user can release the clamping rod 10 and continue to rotate until the limiting block is misaligned with the square groove 3 until the position of the clamping rod 10 corresponds to that of the strip-shaped groove. The elastic force of the clamping spring 12 is used to limit and fix the positioning block 7 by the clamping rod 10 and the limiting groove.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
