Description

Technical Field

[0001] The utility model relates to the technical field of calibration devices, in particular to a pressure transmitter calibration device. Background Art

[0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. After searching, a Chinese patent with the authorization number CN213874790U discloses a calibration device for a pressure transmitter. Although during the calibration process, only the connector and part of the first corrugated hose are exposed outside the casing, the interference of the external environment on the entire calibration process can be effectively reduced during the calibration process, thereby improving the accuracy of the calibration; the exposed length of the first corrugated hose can be adjusted by a sliding mechanism to adapt to calibration in different places, but the bellows of the device will rub against the surface of the shell when pulling out and adjusting the length, which may easily damage the surface of the bellows. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a pressure transmitter calibration device, which solves the problem that the existing device proposed in the background technology may cause scratches on the surface of the bellows when the pipeline is pulled out and adjusted during use, thereby easily damaging the pipeline.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pressure transmitter calibration device, including a device body, a lifting block, a limit groove and a slide groove, quick clamps are installed on the outside of both sides of the device body, the quick clamps are configured to fix the calibration device, the telescopic end of the quick clamps is tightly fitted with the surface of the calibration device, the calibration device is installed inside the device body, the calibration device is connected to one end of the test hose, the top of the device body is connected to one end of the top plate by a hinge, the other end of the top plate is connected to the device body by a buckle, a slide groove is opened on the top of one end of the device body, a slider is arranged inside the slide groove, the inside of the slider is threadedly connected to a threaded rod, the top of the threaded rod is welded to the adjusting rod, and the bottom of the threaded rod is rotatably connected to the top of the top block, the bottom of the top block is tightly fitted with the top of the lifting block, the lifting block is located inside the limit groove, and the limit groove is opened at one end of the device body.

[0005] Preferably, arc grooves are provided at the bottom of the lifting block and the bottom of the limiting groove, and the arc grooves at the bottom of the lifting block and the bottom of the limiting groove are combined into a circular hole groove, which is conducive to fixing the test hose through the arc grooves at the bottom of the lifting block and the bottom of the limiting groove to form a circular hole groove.

[0006] Preferably, grooves are provided on both sides of the lifting block, and the grooves on both sides of the lifting block are slidably connected to the two sides of the limiting grooves. Balls are evenly embedded on the bottom of the limiting groove and the top surface of the lifting block, and the surface of the ball is in sliding contact with the surface of the test hose. The balls are helpful in reducing the friction on the test hose and can make the test hose smoother when being pulled out and adjusted in length.

[0007] Preferably, the cross-section of the slide groove is T-shaped, and the cross-sectional shape of the slide groove is consistent with the shape of the slider. The slide groove is slidably connected to the slider, and a circular groove is provided at the bottom of the slider. The circular groove at the bottom of the slider is consistent with the shape and size of the top block, which facilitates the slider to slide inside the slide groove. By sliding the slider to one side of the slide groove, the lifting block inside the limit groove can be taken out, thereby facilitating the test hose to be placed inside the limit groove.

[0008] Preferably, a plurality of card slots are arranged on both sides of the bottom of the limit slot, the card slots are in a C-shaped structure, and the card slots are engaged with the hose, and balls are embedded on the surface of the card slots, and the balls on the surface of the card slots are in sliding contact with the surface of the test hose, thereby facilitating fixing the test hose through the card slots while avoiding affecting the length adjustment of the test hose when pulling out.

[0009] Preferably, there is a gap between the slots, and fixing rings are glued on both sides of the slots. The fixing rings are mounted on the outside of the spring tube, and one end of the spring tube is embedded in the main body of the device. Due to the presence of the spring tubes on both sides of the test hose, the test hose can bend naturally, avoiding the test hose from bending at too large a bending angle, which would affect the circulation of the medium inside the test hose.

[0010] The utility model provides a pressure transmitter calibration device, which has the following beneficial effects:

[0011] (1) A pressure transmitter calibration device, when in use, slides the lifting block upward, so that the lifting block can be moved out of the limit groove, and then the test hose is placed in the limit groove, and the lifting block is put back into the limit groove, and then the slider is slid so that the slider can slide in the slide groove. When the slider moves to the top of the limit groove, the adjusting rod is rotated so that the adjusting rod can drive the threaded rod to rotate, and then the threaded rod can drive the top block to move downward. The top block moves downward and abuts against the top surface of the lifting block, so that the lifting block can clamp the surface of the test hose, so that the test hose can be fixed. When the test hose is pulled out, it will contact the steel balls on the limit groove and the surface of the lifting block, and then the steel balls are helpful to reduce the friction on the test hose, and at the same time, the test hose can be pulled out more smoothly when adjusting its length.

[0012] (2) A pressure transmitter calibration device, when in use, fixes the surface of the test hose by setting a plurality of slots on both sides of the limit slot. When there is a height difference between the two ends of the test hose, the test hose will bend. Due to the presence of spring tubes on both sides of the test hose, the test hose can bend naturally, avoiding the test hose from bending at an excessively large bending angle, thereby affecting the flow of the medium inside the test hose.

[0013] This solves the problem that when the existing device is used, the surface of the corrugated pipe is scratched when the pipe is pulled out and adjusted, which in turn causes easy damage to the pipe. BRIEF DESCRIPTION OF THE DRAWINGS
