The present application provides an operating sound eliminating device for a semi-active engine mount of a vehicle, in the configuration of an electromagnetic valve for opening and closing an air chamber of the semi-active engine mount, a plurality of layers are adopted for an upper stopper, so that not only the air tightness and durability of the upper stopper can be improved, but also the impact when the upper stopper hits a valve housing can be absorbed while reducing noise.

This invention proposes a novel steel structure seismic-resistant block, fixedly installed at the bottom of a steel box girder and on the inner side of the pier support. It includes a damping plate and a stiffening plate. The damping plate is fixedly mounted on a fixed frame composed of stiffening plates, facing the pier support. The fixed frame is fixedly mounted at the bottom of the steel box girder. The damping plate includes a plate bearing and evenly distributed nails on the plate bearing. Both the plate bearing and the nails are made of neoprene rubber. This invention achieves its damping function by using a neoprene rubber damping plate instead of the original elastic structure. It serves as a primary energy-dissipating structure, with a stiffening plate behind the damping plate acting as a secondary energy-dissipating structure. This multi-layered energy-dissipating structure results in better overall damping performance, effectively absorbing and attenuating vibrations, and reducing the impact of lateral slippage of the superstructure on the pier.

The utility model relates to the technical field of shielding door design, and discloses a shielding door with a damping device, which comprises a mounting frame, the right end of the front side of the mounting frame is connected with a shielding door body through a hinge, the top end and the bottom end of the front side of the shielding door body are respectively provided with a transverse sliding groove, and the transverse sliding grooves at the two ends are internally provided with a limiting assembly. And the left end of the rear side of the mounting frame is fixedly connected with a connecting block. According to the utility model, when the shielding door body is closed, the shielding door body is in contact with the spring damper, so that the impact force can be effectively buffered, the damage to the shielding door body is reduced, the overall service life is further prolonged, and the replacement cost is reduced. After the shielding door is closed, through simple operation, namely moving the limiting sliding rod, pulling and loosening the telescopic connecting piece, and increasing friction force between the telescopic connecting piece and the limiting sliding rod by utilizing reset acting force of the telescopic connecting piece, the telescopic connecting piece is not prone to moving, the operation is simple, professional skills are not needed, the shielding door can be further fixed, stability and safety in the closed state can be further improved, and accidental opening is prevented.

The utility model relates to the technical field of water interception ditch, concretely to a water interception ditch with water and dirt separation structure, it is a water interception ditch with water and dirt separation structure, purpose solves the traditional water interception ditch usually only has single drainage function, the leaves and other sundries carried by rainwater are directly drained into natural water body, not only easy to cause the drainage pipeline of water interception ditch to be blocked, still can cause the problem of surrounding environment pollution, therefore enhanced the use efficiency and effect of water interception ditch, including water interception ditch body and apron, the water interception ditch body sets up as the recess shape, the apron sets up at the top of water interception ditch body, the water interception ditch body is by concrete pouring and is formed, the water interception ditch body is provided with separation mechanism, the separation mechanism still includes separation board and support plate, the apron top end is provided with multiple groups of drain holes, the separation board periphery inner wall is provided with multiple groups of separation through -hole, water interception ditch body inner wall left and right ends fixed mounting has support plate.

The utility model discloses a rear shock absorption folding frame of a rectangular pyramid structure, which comprises a front frame, a middle tube, a rear frame, a shock absorber and a shaft barrel, the front frame is connected with the front side of the middle tube, one end of the shock absorber is hinged with the rear side of the upper part of the middle tube, the axis of the shaft barrel is vertical to the axis of the middle tube and is fixedly welded on the rear side of the bottom end of the middle tube, and the upper side of the rear frame is connected with the other end of the shock absorber. The lower side of the rear frame is rotationally connected with the shaft barrel; the rear frame comprises a left frame and a right frame; the shock absorber comprises a shock absorption head, a shock absorption tail, an elastic body and a bolt shaft rod, the shock absorption head comprises a hollow tubular cylinder body and a hinge joint arranged at one end of the cylinder body, the hinge joint is provided with a hinge through hole and a threaded hole, the axis of the hinge through hole is perpendicular to the axis of the cylinder body, the axis of the threaded hole is coaxial with the axis of the cylinder body, and the shock absorption tail comprises a telescopic pipe and a connecting pipe which are connected in a three-way tubular mode. The strength of the bicycle frame can be guaranteed, and the shock absorption performance of the shock absorber can be well exerted.
