[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 , the figure shows a composite pressure plate structure for automobile air-conditioning pipes, including a pier head 1 and a mounting structure 2 mounted on the surface of the pier head 1, the mounting structure 2 including a pressure plate 201, two pressure plates 201 are symmetrically arranged, and the adjacent ends of the two pressure plates 201 are provided with a semicircular notch 204, the outer circular surface of the pier head 1 is sleeved inside the semicircular notch 204, and the outer circular surface of the pier head 1 is fixedly connected to two symmetrically arranged positioning blocks 205, the pressure plate 201 is located in the semicircular notch 204 and has a positioning groove 203 on its arc side, and the positioning groove 203 matches the positioning block 205. It should be noted that the pier head 1 During the installation process, first connect the pier head 1 with the assembly pipeline, then the semicircular notches 204 on the two pressure plates 201 are sleeved on the outer wall of the pier head 1 and connected, and then the positioning block 205 is moved to the inside of the positioning groove 203, thereby completing the merger and alignment of the two pressure plates 201. The aligned pressure plates 201 will not rotate or move around the surface of the pier head 1. After the two pressure plates 201 are merged, the two mounting holes 202 are pieced together into a circle, and the bolt assembly is docked and installed, and positioned. The installation process will not cause hole deviation, affecting the installation efficiency, so that the mounting holes can be quickly aligned, and the installation operation process saves time and effort.

[0020] See also Figure 2 and Figure 3 The positioning block 205 and the positioning groove 203 are both arc-shaped, and the pressure plate 201 is also provided with a semicircular mounting hole 202. It should be noted that the use of the arc-shaped positioning block 205 makes the protrusion occupy a smaller area, can fit the shape of the pier head 1, and increases the aesthetics of positioning use.

[0021] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5, a filter screen 3 is installed at one end of the pier head 1 through a detachable structure 4, and the detachable structure 4 includes a rotating ring 401. Filter screens 3 are sleeved inside both ends of the pier head 1, one of the filter screens 3 is fixedly connected to the pier head 1, and the other filter screen 3 is detachably connected to the pier head 1. A rotating ring 401 is sleeved on the outside of one end of the pier head 1, and a plurality of annular long cavities 407 are opened on the surface of the pier head 1 at the position of the rotating ring 401. A plurality of springs 405 are fixedly connected to the inner surface of the rotating ring 401, and the other end of the spring 405 arranged in the long cavity 407 is fixedly connected to the card block 402. A plurality of annular pads 403 are fixedly connected to the inside of the two ends of the pier head 1, a pad 403 is provided on one side of the filter screen 3, and a card block 402 is provided on the other side of the filter screen 3. It needs to be explained The particularity is that, during the installation process of the filter 3, first manually rotate the rotating ring 401, and the annular spring 405 drags the block 402 to move in a circle. As the manual rotation continues, the block 402 is squeezed, and the spring 405 is squeezed and contracted, and the block 402 is completely moved inside the long cavity 407. The block 402 will not be located on the inner side of the pier head 1 to produce a bulge. After the filter 3 is placed in, it will contact the pad 403, and then the rotating ring 401 can be rotated in the opposite direction again to move the block 402 out of the inner side of the pier head 1 to produce a bulge. Thus, the blocks 402 and pads 403 are respectively provided on both sides of the filter 3, which can limit the removal of the filter 3, so that the filter 3 can be quickly assembled. The filter 3 is sealed after long-term use, which is convenient for regular replacement, and the assembly operation is simple and convenient.

[0022] See Figure 4 The outer surface of the rotating ring 401 is provided with a number of annular and integrally formed ridges 404. It should be noted that friction is generated during the hand contact process, and manual rotation of the rotating ring 401 is not prone to slipping.

[0023] See Figure 4 The side of the block 402 away from the spring 405 is chamfered in an arc shape. It should be noted that the block 402 is squeezed to generate force components at different angles, so that the block 402 is squeezed and moves toward the spring 405, thereby facilitating the contraction process of the block 402 and the spring 405.

[0024] The pier head 1 is located between the two filter screens 3 and is filled with block activated carbon. The activated carbon has an adsorption effect and can effectively absorb odors and some toxic gases, providing a good breathing environment for using air conditioning.

[0025] Working principle: During the installation process of the filter 3, first manually rotate the rotating ring 401, and the ring-shaped spring 405 drags the block 402 to move in a circle. As the rotating ring 401 is manually rotated, the side of the long cavity 406 of the block 402 is squeezed, and the spring 405 is squeezed and contracted, and the block 402 is completely moved inside the long cavity 407. The block 402 will not be located on the inner side of the pier head 1 to produce a bulge. After the filter 3 is placed in, it will contact with the pad 403. The rotating ring 401 can be rotated in the opposite direction again to move the block 402 out of the inner side of the pier head 1 to produce a bulge. Therefore, the block 402 and the pad 403 are respectively provided on both sides of the filter 3, thereby limiting the horizontal movement of the filter 3, thereby completing the installation process of the filter 3.
