The utility model relates to the technical field of crushing equipment, and disclose a building material processing crushing equipment, this building material processing crushing equipment, including the machine body, the outer wall of machine body is provided with the crushing subassembly, the inner wall hinged of machine body has the movable door, the inside of machine body is provided with the protection mechanism, the inside of machine body is provided with the promotion mechanism. This building material processing crushing equipment, the protection board can rotate in the arc surface of straight bar, the setting of torsional spring is convenient raw material enters the machine body, the protection board is extruded by raw material, torsional spring deformation, makes the protection board swing, convenient raw material enters the machine body, convenient feeding torsional spring reset, the protection board reset prevents the material that breaks and splashes, the serrated setting of multiple rubber strips is convenient to the strength of the rebound material buffering, convenient the raw material bounces back to the inside lower end of machine body, the distance of protection board is limited by the limiting rod, prevents the material splashing from injuring the personnel outside.

The utility model relates to the sealing device field for door, especially prevent clamping prevent dragging rubber strip subassembly and door. Through the support limit top edge of inside and / or outside of sensitive element installation cavity of setting on at least one of the pair of two anti -pinch rubber strip, and the other anti -pinch cooperation in the front -back direction, in two anti -pinch rubber strip sealing cooperation state, through the support of support limit top edge, the pair of two anti -pinch rubber strip is limited in the front -back direction, can limit the distance between the sensitive element of one anti -pinch rubber strip and another anti -pinch rubber strip main part, avoid because the body vibration leads to two anti -pinch rubber strip to further close and misfire sensitive element, lead to misfire, so need not to carry out signal shielding to sensitive element, in the door closed state two anti -pinch rubber strip between clamping the situation such as belt or rope, sensitive element can also be triggered and deliver to vehicle controller signal, realize prevent dragging function.

This utility model relates to the field of condenser technology, and provides a condenser for the preparation of 5-chloropentanoyl chloride, including a condenser body; a support plate is fixedly installed at the bottom of the condenser body, a support mechanism is provided on the surface of the condenser body, and a guide mechanism is provided on the surface of the condenser body; a protective mechanism is provided on the surface of the guide plate; a buffer assembly is provided on the inner wall of the protective mechanism; through the arrangement of the L-shaped fixing frame, vertical plate, reinforcing rib, guide plate and limiting plate, the cooperation of the L-shaped fixing frame and the vertical plate can provide stable support for the guide mechanism, and can keep the protective mechanism stable during protection, preventing it from tilting; the reinforcing rib can enhance the connection strength between the guide plate and the vertical plate; the guide plate can allow the two sets of sliding plates to slide stably on its surface, so that the arc-shaped protective net can slide at a certain angle to buffer when it is impacted.

The utility model relates to tensile test equipment field, specifically disclose a clamping device for tensile test, including chuck shell, chuck and adjusting lever, chuck shell front end sets up the loading hole, and the chuck is located in the chuck shell, and the chuck is composed of base and several clamping blocks, and the annular array of several clamping blocks is in the base one side, and the base other side is rotatably connected with the adjusting lever, and the middle of chuck shell rear end sets up the threaded hole, and the one end of adjusting lever passes through the threaded hole and is located in the outside of chuck shell, and the outer periphery of adjusting lever is connected with the threaded hole screw thread, and the one end side surface fixed sleeve rotating block of adjusting lever is located in the outside of chuck shell, through the chuck installation in the chuck shell, the distance between the clamping block on the chuck is limited through the chuck shell, can adjust the position between the chuck and the chuck shell through the rotation adjusting lever to control the distance between the clamping block, and set up clamping block has multiple, can hold the cylinder structure.
