Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline fixed connection structure for an air compressor. Background Art

[0002] When the piston of a piston air compressor reciprocates in the cylinder and moves to the right, the pressure in the left chamber of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and the outside air is sucked into the cylinder. This process is called the compression process. When the piston air compressor is working, it needs to discharge the compressed gas, and the discharge must be carried out through some pipe connections. The pipe connection method is all through bolt thread connection, and this connection method makes it troublesome and inconvenient to install and disassemble the pipe. When some vertical pipes are connected, they cannot fix the lower end pipe well. After a long time, the pipe will fall due to the gravity of the pipe, thereby affecting the transportation of gas in the pipe and affecting its efficiency.

[0003] Announcement No. CN 210398014 U discloses a pipeline connection structure for an air compressor, wherein an arc-shaped slider 1 and an arc-shaped slider 2 symmetrically fixedly installed on a first tube body and a second tube body are respectively connected to a concave circular slide groove 1 and a concave circular slide groove 2 provided on the inner walls at both ends of a connecting tube, and the two ends of the pipeline are sealed by a rubber sealing ring 1 fixedly installed on the inner wall of the connecting tube, and the upper buckles symmetrically fixedly installed on the side walls at both ends of a circular sleeve 1 fixedly installed on the connecting tube are detachably connected and fixed to the lower buckles symmetrically fixedly installed on the side walls at both ends of a circular sleeve 2 fixedly installed on the second tube body, so as to fix the pipeline. Compared with the existing device, the device has a simple structure and convenient operation, is more convenient to install and disassemble the pipeline, and is more stable to fix the pipeline, thereby improving the practicality and stability of the device. However, the patent still has the following problems in actual use:

[0004] The pipe connection structure for the air compressor utilizes the characteristics of the upper buckle and the lower buckle for the snap connection to realize the connection between the first tube body and the second tube body. However, during the long-term use of the first tube body and the second tube body, the buckle will become loose, and the tightness of the connection between the first tube body and the second tube body cannot be guaranteed. The sealing of the connection is improved by a rubber sealing ring, but because the rubber sealing ring fits the surface of the first tube body and the second tube body, the first tube body and the second tube body cannot be quickly aligned and connected when connecting the first tube body and the second tube body. At the same time, the rubber sealing ring will soften and be damaged during long-term use, affecting the connection efficiency of the first tube body and the second tube body.

The specific contents are as follows:

[0022] 1. By setting a fixed connection mechanism, not only can the characteristics of the sliding connection between the connecting inner ring at the top of the first connecting tube and the variable inner ring at the bottom of the second connecting tube be utilized to realize the rapid positioning and splicing of the first connecting tube and the second connecting tube, but when the bottom of the inclined hook contacts and slides with the top of the connecting block, the inclined hook is rotated.

At the same time, the clamping baffle squeezes the connecting inner ring under the action of the top spring, further improving the tightness of the connection of the connecting inner ring. At the same time, the clamping support rod drives the bottom spring to clamp the filter ring, thereby realizing the fixing of the filter screen. When the filter screen needs to be replaced, the filter ring and the filter screen can be quickly disassembled by utilizing the characteristics of the sliding connection between the mounting slide block and the mounting slide groove, thereby cleaning and replacing the filter screen. By utilizing the characteristics of the rotatable connection between the rotating bearing and the clamping ring, when there is air circulation inside the second connecting tube, it will drive the spiral cleaning blade to rotate, thereby cleaning the inner wall of the second connecting tube to prevent dust from adhering to the inside of the second connecting tube and affecting the air circulation.

[0023] 2.

[0038] Working principle: Before using this air compressor pipe fixing connection structure, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig. 9 As shown, first, when connecting the air compressor pipeline, the connection inner ring 103 at the top of the first connecting pipe 101 and the variable inner ring 110 at the bottom of the second connecting pipe 105 are used to slide and connect, so as to realize the rapid positioning and splicing of the first connecting pipe 101 and the second connecting pipe 105. When the bottom of the inclined hook 115 contacts and slides with the top of the connecting block 102, the inclined hook 115 rotates. When the first connecting pipe 101 and the second connecting pipe 105 are closely spliced, the inclined hook 115 is snap-connected with the connecting block 102, so as to realize the preliminary fixation of the first connecting pipe 101 and the second connecting pipe 105. Since the spacing between the connecting blocks 102 is fixed, a certain gap will appear when the first connecting tube 101 and the second connecting tube 105 are spliced. By compressing the gap and turning the fixing knob 107 to drive the fixing nut sleeve 106 to rotate, and utilizing the characteristics of the threaded connection between the fixing nut sleeve 106 and the fixed external thread 108, under the action of the variable trapezoidal groove 109, the fixing external thread 108 is compressed and contracted.

[0039] Secondly, when the first connecting tube 101 is tightly connected to the second connecting tube 105, the connecting inner ring 103 squeezes the clamping ring 126, so that the clamping ring 126 drives the clamping sliding sleeve 125 to slide inside the clamping slide groove 122 under the action of the clamping spring 124, and at the same time, the clamping baffle 130 squeezes the connecting inner ring 103 under the action of the top spring 131, further improving the connection tightness of the connecting inner ring 103, and at the same time, the clamping support rod 133 drives the bottom spring 134 to compress the filter ring 119, thereby achieving the fixation of the filter screen 120 When the filter 120 needs to be replaced, the filter ring 119 and the filter 120 can be quickly disassembled by utilizing the sliding connection between the mounting slider 121 and the mounting groove 104, so that the filter 120 can be cleaned and replaced. By utilizing the rotating connection between the rotating bearing 127 and the clamping ring 126, when air circulates inside the second connecting pipe 105, the spiral cleaning blade 128 will be driven to rotate, thereby cleaning the inner wall of the second connecting pipe 105 to prevent dust from adhering to the inside of the second connecting pipe 105 and affecting the air circulation.

[0040] Finally, the rotating knob 208 is used to drive the rotating worm 207 to rotate, and the rotating ring 204 and the second connecting pipe 105 are rotated by utilizing the characteristics of the meshing connection between the rotating worm 207 and the rotating worm wheel 205. When connecting the bent pipe, the angle of the bent pipe can be adjusted by changing the angle of the second connecting pipe 105, which facilitates the installation of the air compressor pipeline.
