The utility model relates to inner suspension pole sensor installation technical field, and disclose a kind of sensor mounting structure of inner suspension pole, comprising: mounting bracket, the mounting bracket with the sensor fixed connection, the mounting bracket includes fixed connection lower module, the surface of lower module is equipped with semicircular groove;Upper module, with the symmetrical distribution of lower module, surface is equipped with the semicircular groove of same size with lower module;Guiding limiting structure, the upper module is connected or fixed with the mounting bracket by the guiding limiting structure;Clamping structure, the clamping structure is connected with the lower module, the clamping structure includes handle, the clamping structure is connected with the upper module;The utility model solves the problem that traditional installation mode is prone to rotating displacement around pole, causes measuring datum plane to deviate, affects inclination measurement precision, installation difficult.

The utility model discloses a double row tooth shock absorber technical field's a double row tooth shock absorber gear ring limit baffle, including shock absorber casing, the inside installation of shock absorber casing has double row gear, and the both ends of shock absorber casing are close to double row gear respectively and are provided with gear ring limit component, and the gear ring limit component includes limit baffle, and the one end of limit baffle is connected with output shaft, and the one end of limit baffle away from output shaft is provided with first connecting flange, the gear ring limit baffle of double row tooth shock absorber of this scheme design, through the structural design of baffle connecting cover and baffle adjusting groove, has realized the transition fit between limit baffle and shock absorber casing effectively, avoided the friction contact between limit baffle and double row gear, reduced the problem of excessive wear and heat accumulation, through the structural design of the sliding fit between sealing guide ring and annular guide groove, has further improved the stability of limit baffle, ensures that limit baffle does not occur position deviation under high -strength impact or vibration condition.

The utility model provides a rotating equipment outlet pipeline expansion joint limiting structure, and relates to the technical field of expansion joint limiting installation, the spacing between a group of fixing steel is adjustable, a plurality of groups of fixing steel are arranged on pipeline flanges on the two sides of a rubber expansion joint, and each group of fixing steel is matched with a plurality of groups of fixing bolts to achieve position locking. And meanwhile, the long screw plays a role in double limiting the expansion joint, when the rubber expansion joint extends and expands outwards due to dynamic pressure, the double nuts on the outer side limit the expansion amount, and when the rubber expansion joint is compressed, the double nuts on the inner side play a role in compression limiting. Therefore, the safety of the expansion joint is guaranteed when the state of the rotating equipment outlet pipeline changes sharply, and the large bearing capacity is guaranteed when the state of the rotating equipment outlet pipeline changes due to the adoption of the fixed steel type.

This utility model discloses a loop fixing structure for an anti-exposure lining, which includes two connectors respectively located at the lower left and right ends of the lining body; an elastic loop strap with an interface for fitting onto the body, and an adjustment structure for adjusting the size of the interface; and two connecting ends, both located on the loop strap, for connecting the connectors respectively. Because the loop strap is made of elastic material, when the interface is enlarged by adjusting the buckle, it can be easily fitted onto the outside of the underwear. The interface can then be tightened by adjusting the buckle to fix it to the underwear. After fixing the upper end of the anti-exposure lining to the underwear, the first and second figure-9 buckles on the loop strap are connected to the two connectors on the lining body to fix the lower end of the lining body, thus ensuring that the anti-exposure lining will not shift during use, making it more comfortable to wear and highly practical.
