Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more particularly to a high-strength automobile corrugated flexible connecting pipe. Background Art

[0002] The automotive flexible pipe is an important connecting component of the automotive exhaust system. It is generally installed at the front of the exhaust system, very close to the vehicle engine, and is exposed to high temperature and vibration. The automotive flexible pipe absorbs the vibration of the exhaust system and prevents excessive thermal deformation, thereby isolating the displacement of the vehicle engine on the exhaust system, reducing the noise of the exhaust system, and providing a comfortable ride. The automotive flexible pipe is double-layer corrugated and covered with a steel mesh sleeve.

[0003] In response to this, Chinese patent application number CN202220521282.X discloses a high-strength corrugated pipe for automotive exhaust pipes, comprising a bellows body, a wire mesh sleeve movably attached to the side surface of the bellows body, a connecting pipe fixedly connected to the left side of the bellows body, a clasp movably attached to the side surface of the connecting pipe, and mounting blocks fixedly connected to the top and bottom of the left side of the wire mesh sleeve. The left sides of the two mounting blocks movably engage with the top and bottom of the right side of the clasp, respectively. The high-strength corrugated pipe for automotive exhaust pipes is inserted into a mounting groove via the mounting blocks. The clasp blocks contact the outer side of the mounting blocks and move into the movable groove. The elastic force of the return spring then ejects the clasp blocks into the wedge-shaped slot. Two fixed blocks on the connecting pipe engage with two grooves in the clasp, allowing the two clasps to position the ends of the wire mesh sleeve, preventing the sleeve from rotating or moving, thereby facilitating the positioning and installation of the wire mesh sleeve on the bellows surface.

[0004] The bellows uses a clamping ring to position the two ends of the wire mesh sleeve, but the wire mesh sleeve is fixed by the cooperation of a clamping block and a wedge-shaped slot. Since the clamping block is located on the inner side of the clamping ring, the specific position of the clamping block cannot be observed during installation, and the wire mesh sleeve that drives the wedge-shaped slot cannot be quickly connected to the clamping block, making the connection between the wire mesh sleeve and the clamping block inconvenient and requiring multiple angle adjustments for installation, affecting the assembly efficiency of the device.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a high-strength automotive corrugated flexible connecting pipe. Utility Model Content

[0024] See also Figure 1-4 The utility model provides a high-strength automobile corrugated flexible connecting pipe embodiment:

[0025] The connecting pipe body 1, connecting head 11 and wire mesh sleeve 12 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here.

[0026] A high-strength automotive corrugated flexible connecting pipe comprises: a connecting pipe body 1, two ends of the connecting pipe body 1 are connected to connectors 11, and the outer side of the connecting pipe body 1 is covered with a steel mesh sleeve 12;

[0027] A connecting structure 2 is installed on the outside of the connecting head 11, and the connecting structure 2 includes a threaded sleeve 21. The threaded sleeve 21 is installed on the outside of the connecting head 11 through a threaded movement. A movable groove 22 is provided on the surface of the threaded sleeve 21, and a guide rod 23 is slidably installed on the inner side of the movable groove 22. The end of the guide rod 23 is fixedly connected to a splint 24, and a spring 25 is fixedly connected to the surface of the guide rod 23. A bolt 26 is threadedly connected to the splint 24, and a groove 27 is provided on the outer wall of the splint 24. The threaded sleeve 21 is installed on the connecting head 11 through a threaded movement. After the wire mesh sleeve 12 is sleeved on the outside of the connecting pipe body 1, the threaded sleeve 21 can be rotated to install the two sets of threaded sleeves 21 on the two sets of connecting heads 11 at both ends of the connecting pipe body 1 respectively. The distance between the two sets of splints 24 is greater than the wire mesh sleeve 1 The two sets of clamps 24 are respectively located at the upper and lower sides of the wire mesh sleeve 12, and then the bolts 26 are rotated with the tool. The bolts 26 are threadedly connected with the two sets of clamps 24. The rotation of the bolts 26 drives the two sets of clamps 24 to move closer to each other. The clamps 24 can drive the guide rods 23 to slide in the movable grooves 22 and stretch the springs 25, so that the two sets of clamps 24 can respectively fit the upper and lower surfaces of the wire mesh sleeve 12. The setting of the friction pad can increase the friction between the clamps 24 and the wire mesh sleeve 12 to prevent the wire mesh sleeve 12 from detaching from the inner side of the clamps 24. The connector 11 can be used to press against the wire mesh sleeve 12 on the inner and outer sides to fix the two ends of the wire mesh sleeve 12, thereby further improving the assembly convenience of the device.

[0028] Furthermore, a shielding structure 3 is installed on the connecting structure 2, and the shielding structure 3 includes a shielding sleeve 31, which is sleeved on the outside of the connection between the wire mesh sleeve 12 and the splint 24. The first rubber band 32 and the second rubber band 33 are inserted into the two ends of the shielding sleeve 31. The first rubber band 32 and the second rubber band 33 are stretched open, and the first rubber band 32 can be sleeved on the inner side of the groove 27, and the second rubber band 33 can be sleeved on the outside of the wire mesh sleeve 12. The shielding sleeve 31 is sleeved on the outside of the connection between the wire mesh sleeve 12 and the splint 24, and can shield the gap between the wire mesh sleeve 12 and the splint 24, preventing impurities such as water stains from entering the inside of the splint 24, causing the friction pad provided on the inner wall of the splint 24 to accelerate aging and damage, affecting the fixing effect of the splint 24 and the wire mesh sleeve 12.

[0029] Furthermore, two groups of threaded sleeves 21 are provided, and the two groups of threaded sleeves 21 are respectively located on the two groups of connecting heads 11. The two groups of threaded sleeves 21 can limit the installation of the wire mesh sleeve 12 on the outside of the connecting pipe body 1 on both sides.

[0030] Furthermore, two groups of splints 24 are installed on a group of threaded sleeves 21, and three groups of guide rods 23 are connected to one group of splints 24. One end of the spring 25 is fixedly connected to the inner wall of the movable groove 22. The three groups of guide rods 23 can limit the movable direction of the splint 24 on the threaded sleeve 21, so that the two groups of splints 24 can only approach or move away from each other.

[0031] Furthermore, the two sets of splints 24 are fixedly connected by bolts 26, and a friction pad is bonded to the inner wall of the bolts 26. The setting of the bolts 26 can clamp the splints 24 on the outside of the wire mesh sleeve 12, and the setting of the friction pad can increase the friction between the splints 24 and the wire mesh sleeve 12.

[0032] Furthermore, the first rubber band 32 is sleeved in the groove 27, and the second rubber band 33 is sleeved on the outside of the wire mesh sleeve 12. The first rubber band 32 cooperates with the second rubber band 33 to fix the cover 31 on the outside of the connection between the wire mesh sleeve 12 and the splint 24. The cover 31 can block the gap between the wire mesh sleeve 12 and the splint 24 to prevent water stains and other impurities from entering the inside of the splint 24, causing the friction pad provided on the inner wall of the splint 24 to accelerate aging and damage, affecting the fixing effect of the splint 24 and the wire mesh sleeve 12.
