[0025] The effect achieved by the entire embodiment 1 is that when fixing the pressure transmitter, the wire-receiving base plate 1 is fixedly installed with the equipment or the installation site by multiple bolts, and the mounting plate 3 is supported by multiple support rods 2. The pressure transmitter is placed at the top center of the placement plate 4, and the hand wheel set on one side of the two-way threaded rod 5 is held and rotated clockwise, and the two mounting frames 6 will move toward each other on their surfaces, and vice versa. When the two mounting frames 6 drive the two replacement components 7 to move toward each other, the two clamping blocks 710 will clamp and fix the bottom of the pressure transmitter. Since different manufacturers produce different types of pressure transmitters, when fixing them, a clamping block 710 that can adapt to the shape is selected, and the handle groove 704 on one side of the connecting block 703 is first pulled upward, so that the connecting block 703 will drive multiple connecting rods 705 to slide in the mounting block 701, and multiple pushing blocks 707 will push multiple springs 706 during the upward movement. The plurality of limit rods 709 are equidistantly arranged on the other side of the bottom of the connecting block 703, and slide out from the plurality of fixing holes 712, thereby releasing the limit on the slider 711, and facilitating personnel to pull the clamping block 710 to be replaced, so that it is separated from the mounting block 701, and then the adaptable clamping block 710 is inserted into the dovetail groove provided on one side of the mounting block 701, until it contacts the positioning plate 702, and the positioning plate 702 plays a role in rapid positioning, so that the plurality of fixing holes 712 and the plurality of limit rods 709 are positioned correspondingly, and the pulling on the connecting block 703 is released, and the plurality of connecting rods 705 are pushed downward under the elastic reset action of the plurality of springs 706, and then the plurality of limit rods 709 are inserted into the fixing holes 712 corresponding to the positions, thus playing a role in limiting and fixing the slider 711, and facilitating personnel to quickly replace the clamping block 710 adapted to different pressure transmitters, thereby improving the use effect of the pressure transmitter fixing frame.

[0026] Embodiment 2, as Figures 1 - 5 As shown, the sliding assembly 8 includes a fixed frame 801, the inner surface of the fixed frame 801 is symmetrically fixedly connected with a sliding rod 802, the outer surfaces of the two sliding rods 802 are symmetrically slidably connected with moving blocks 803, and the tops of the two moving blocks 803 are fixedly connected to the bottoms of the two mounting frames 6.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, through the coordinated use of the sliding assembly 8, when the two mounting frames 6 move toward or oppositely, they will slide synchronously on the outer surfaces of the two slide bars 802 through the two moving blocks 803 in the fixed frame 801, which plays a limiting role, preventing the outer surface of the mounting frame 6 from rubbing against the inner wall of the mounting plate 3, thereby increasing the movement resistance and further improving the use effect of the pressure transmitter fixing frame.

[0028] Working principle: When fixing the pressure transmitter, the take-up base plate 1 is fixed to the equipment or installation site by multiple bolts, and the mounting plate 3 is supported by multiple support rods 2. The pressure transmitter is placed at the top center of the placement plate 4, and the handwheel set on one side of the two-way threaded rod 5 is held and rotated clockwise. The two mounting brackets 6 will move toward each other on the surface, and vice versa. The two mounting brackets 6 will move in the opposite direction on the surface. When the two mounting brackets 6 drive the two replacement components 7 to move toward each other, the two clamping blocks 710 will clamp and fix the bottom of the pressure transmitter. Since different manufacturers produce different types of pressure transmitters, when fixing them, a clamping block 710 that can adapt to the shape is selected. First, the handle groove 704 on one side of the connecting block 703 is pulled upward, so that the connecting block 703 will drive the multiple connecting rods 705 to slide in the mounting block 701. During the upward movement, the multiple pushing blocks 707 will squeeze the multiple springs 706 to cause them to deform and shrink, and then the multiple limiting rods 709 equidistantly arranged on the other side of the bottom of the connecting block 703 will slide out of the multiple fixing holes 712, releasing the limit on the slider 711, so that The personnel pull the clamping block 710 to be replaced to separate it from the mounting block 701, and then insert the adaptable clamping block 710 into the dovetail groove opened on one side of the mounting block 701 until it hits the positioning plate 702. The positioning plate 702 plays a role in rapid positioning, allowing the positions of the multiple fixing holes 712 and the multiple limiting rods 709 to correspond. The pulling on the connecting block 703 is released, and the multiple connecting rods 705 are pushed downward under the elastic reset action of the multiple springs 706, so that the multiple limiting rods 709 are inserted into the fixing holes 712 corresponding to the positions. , which plays a role in limiting and fixing the slider 711, making it convenient for personnel to quickly replace the clamping block 710 adapted to different pressure transmitters, thereby improving the use effect of the pressure transmitter fixing frame. Through the coordinated use of the sliding assembly 8, when the two mounting frames 6 move toward or oppositely, the two moving blocks 803 in the fixing frame 801 will slide synchronously on the outer surfaces of the two slide bars 802, thereby playing a role in limiting, preventing the outer surface of the mounting frame 6 from fitting and rubbing against the inner wall of the mounting plate 3, thereby increasing the movement resistance and further improving the use effect of the pressure transmitter fixing frame.
