Description

Technical Field

[0001] The utility model relates to the technical field of air filter element production, in particular to a fixing device for air filter element production. Background Art

[0002] An air filter element is a filter, also called an air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. The engine inhales a large amount of air during operation. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious "cylinder pulling", which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air, ensuring that sufficient and clean air enters the cylinder.

[0003] The fixing device for producing air filter elements in the prior art needs to be cut during actual use, and the length and position of the fixing device are usually fixed. It is not convenient to adjust the fixed position when cutting, which makes it inconvenient to use. Therefore, we propose a fixing device for producing air filter elements to solve the above-mentioned problems. Utility Model Content

[0031] By means of the above mechanism: the fixing sleeve 6 can be driven to move by rotating the threaded rod 5, and the air filter element can be fixed conveniently through the cooperation between the fixing sleeve 6 and the supporting sleeve 7. The supporting frame 4 can be driven to move conveniently through the limiting plate 3, thereby driving the fixing sleeve 6 and the supporting sleeve 7 to move. The limiting plate 3 can be fixed or unlocked conveniently through the fixing mechanism, thereby adjusting the position of the fixing sleeve 6 and the supporting sleeve 7.

[0032] As a preferred solution of the utility model, the top of the base 1 is fixedly connected to a limiting rod 2, and the limiting rod 2 passes through two limiting plates 3. The limiting plates 3 are conveniently limited by the limiting rod 2, so that the limiting plates 3 can move stably laterally.

[0033] As a preferred solution of the utility model, the fixing mechanism includes: two push rods 10, two pull rods 12 and two insertion rods 13; the two push rods 10 are respectively fixedly connected to the side of the two contact plates 9 close to each other, the two contact plates 9 pass through the corresponding limit plates 3, the two pull rods 12 are rotatably connected to the front side of the corresponding push rods 10, the two insertion rods 13 are respectively slidably connected to the side of the two limit plates 3 close to each other, the front sides of the two insertion rods 13 are rotatably connected to the rear sides of the corresponding pull rods 12, a plurality of slots are evenly spaced on the top of the limit plate 3, the insertion rods 13 are adapted to the slots, the movement of the contact plate 9 will drive the push rod 10 to move horizontally, the lateral movement of the push rod 10 will pull the pull rod 12, at this time the movement of the pull rod 12 will pull the insertion rod 13 upward, the upward movement of the insertion rod 13 will break contact with the slot to unlock the limit plate 3.

[0034] As a preferred solution of the utility model, the two limit plates 3 are fixedly connected to the sides away from each other with a horizontal plate 8, and the tops of the two contact plates 9 are slidably connected to the bottoms of the corresponding horizontal plates 8. The horizontal plate 8 is used to conveniently support the contact plates 9 so that the contact plates 9 can slide left and right.

[0035] As a preferred solution of the utility model, the outer walls of the two push rods 10 are sleeved with reset springs 11, and the sides of the two reset springs 11 that are away from each other are respectively fixedly connected to the sides of the two contact plates 9 that are close to each other, and the sides of the two reset springs 11 that are close to each other are respectively fixedly connected to the sides of the two limit plates 3 that are away from each other.

The rotation of the threaded rod 5 can drive the fixing sleeve 6 to move down, and the air filter element is clamped and fixed by the cooperation of the fixing sleeve 6 and the support sleeve 7. When the lateral position of the fixing sleeve 6 and the support sleeve 7 needs to be adjusted, the contact plate 9 is first pushed to move laterally. When the contact plate 9 moves laterally, the reset spring 11 is compressed. At the same time, the movement of the contact plate 9 will drive the push rod 10 to move laterally. The lateral movement of the push rod 10 will pull the pull rod 12. At this time, the movement of the pull rod 12 will pull the insertion rod 13 to move up. The movement of the contact plate 9 will compress the push spring 14. At this time, the insertion rod 13 moves out of contact with the slot to unlock the limit plate 3. At this time, the limit plate 3 can be pushed to move laterally, thereby driving the support sleeve 7 and the fixing sleeve 6 to move laterally. When the support sleeve 7 and the fixing sleeve 6 move to the appropriate position, by loosening the contact plate 9, the reset spring 11 loses its restriction and pushes the contact plate 9 to move laterally and reset. When the contact plate 9 moves, it will drive the push rod 10 to move laterally. At the same time, the push spring 14 loses its restriction and pushes the insertion rod 13 downward. The insertion rod 13 moves downward and engages with the slot to fix the limit plate 3, thereby fixing the fixing sleeve 6 and the support sleeve 7 at the current position, so as to fix air filters of different lengths.
