Including two opposite flange's heating and ventilation pipeline, further include: tight sleeve ring, tight sleeve ring is corresponding two groups between two heating and ventilation pipelines and is sleeved on heating and ventilation pipeline;And first push sleeve structure and second push sleeve structure, first push sleeve structure and second push sleeve structure are respectively sleeved on two heating and ventilation pipelines, second push sleeve structure one end can be inserted into first push sleeve structure and carry out screw connection, first push sleeve structure and second push sleeve structure between screw cooperation to simultaneously push two groups of tight sleeve ring and press in the flange of respective corresponding side heating and ventilation pipeline, so that the flange of two heating and ventilation pipelines is butted and is pressed tightly.

The utility model discloses a kind of elastic braided protective sleeve and telescopic water pipe group cover with double-locking joint, it is related to fluid conveying device field, comprising: joint, the number of joint is two, the joint includes quick -wired base, quick -wired base side is provided with inner core, the inner core outside is equipped with connecting sleeve, the connecting sleeve outside is equipped with sheath, the sheath is connected with quick -wired base screw thread;Inner tube, the two ends of inner tube are respectively connected with two joints, and inner tube is made of elastic material, and the inner tube is close to the one end of joint and is provided with No. 1 aluminum buckle;The utility model is fixedly connected by No. 1 aluminum buckle and No. 2 aluminum buckle respectively with the inner tube and outer tube and joint, forms a double insurance, No. 1 aluminum buckle firmly fixes inner tube in the inner core outside of joint, ensure that the connection of inner tube and joint is tight, not easy to loosen, and No. 2 aluminum buckle is fixed in the connecting sleeve outside with outer tube, further enhance the connection stability of outer tube and joint.

This utility model discloses a clamping device for screen production. It relates to the field of screen production technology and includes: a clamp, with a linkage device slidably connected to the inner wall of the clamp and an anti-slip device fixedly connected to the outer wall of the clamp. The linkage device includes a limiting rod, and a control handle is symmetrically threaded to the outer wall of the limiting rod via a threaded line. By setting the linkage device and the limiting rod, multiple clamps are symmetrically slidably connected and linearly arrayed along their outer walls, enabling multiple clamps to simultaneously clamp the screen. This multi-point coordinated action can evenly distribute the clamping force to multiple edge positions of the screen, avoiding the problem of excessive local force that occurs when using traditional single-point or few-point clamping. It is especially suitable for large-size screen production, effectively reducing the risk of screen breakage and deformation due to uneven force. The slider achieves the purpose of fixing the clamp through its sliding connection with the limiting rod.

The utility model belongs to the technical field of logistics tractors, and particularly discloses a buffering type traction connection rubber pad of a logistics tractor. The buffering gasket comprises a gasket body arranged on one side of the tractor, a traction seat is arranged on one side of the gasket body, a buffering assembly is arranged in the gasket body and comprises a buffering cushion, and a buffering cavity is formed in the buffering cushion and used for conducting traction buffering on the traction seat. Impact force can be uniformly dispersed, impact strength can be relieved, damage risks of connecting parts can be reduced through the honeycomb-shaped buffering cavities of the buffering assemblies, the contact area of rubber and air is increased through the corrugated inner wall protruding blocks in the cavities, energy is absorbed through the air damping effect, the buffering effect is enhanced, connection is more stable, meanwhile, abrasion of the connecting parts can be reduced, and the service life of the connecting parts is prolonged. The service life of the device and the rubber pad is prolonged, the maintenance cost is reduced, safe and reliable transportation is guaranteed, the part loosening risk is reduced, efficient and stable connection guarantee is provided for logistics transportation, and the transportation efficiency and quality are improved.
