The utility model provides a car carrier binding device, which belongs to the field of binding devices.The car carrier binding device is composed of a car supporting plate, a vertical plate, a rolling mechanism, a binding mechanism and a pushing mechanism, in the scheme, a rotating shaft is convenient to rotate through arrangement of a hand wheel, the rotating shaft rotates to drive gears to rotate, and the two gears are meshed with each other, so that the two gears rotate at the same time; the gear rotates to drive the winding roller to rotate, the winding roller rotates to wind the binding belt, so that the binding belt can be bound more tightly, the pawl can be propped through the elastic force of the spring, the pawl is meshed with the ratchet wheel, and the ratchet wheel can only rotate in one direction through meshing of the pawl and the ratchet wheel. The ratchet wheel is arranged on the winding roller, so that the binding belt can be tighter and tighter when the winding roller winds, when the binding belt is tightened by winding, the pawl and the ratchet wheel are meshed to limit rotation of the winding roller, the through hole is used for hooking the hook, the hook is used for fixing one end of the binding belt, the binding belt can be arranged on a wheel of a car in a sleeving mode, and therefore a tire is bound.

The utility model provides a kind of combined hoop for cable, belong to hoop field, it is by half hoop, connecting mechanism, anti-loosening mechanism, support mechanism and adjusting mechanism constitute, in the scheme, through fixed screw C mobile insertion in mounting ring, and fixed screw C is threadedly connected on half hoop, can limit nut rotation, so that nut cannot rotate, ensure that two half hoops cannot be separated after assembly, since cross arm is rotated by pivot, so that the inclination angle of cross arm can be adjusted, to facilitate the inclination angle of cross arm is adjusted according to the height difference of multiple cables, the setting is used for fixing cross arm by fixed screw B, to limit the rotation of cross arm, and fixed screw B is detached from mounting disc separation, so that cross arm can be rotated, moving can drive connecting seat to move by guide rod, to adjust the distance between connecting seat and cross arm, so that the distance between two connecting seats can be adjusted according to the distance between cable.

The utility model discloses a mask device for a 1.5 kV direct current circuit breaker, and belongs to the technical field of masks of circuit breakers. The mask device comprises a circuit breaker body, a mask is installed on one side of the circuit breaker body, a rotating mechanism is installed on the front surface of the mask, the rotating mechanism comprises a first annular groove, and the first annular groove is formed in the front surface of the mask; when the limiting groove and the clamping groove are oppositely arranged, namely, the rotating disc can be adjusted, and when the rotating disc is rotated, the limiting disc cannot make contact with the rotating disc under the action of the clamping groove, so that the rotating disc can be adjusted, or when the limiting groove and the clamping groove are oppositely arranged, the limiting disc is rotated to enable the position of the clamping groove to be changed, and the rotating disc cannot make contact with the rotating disc. At the moment, the limiting disc blocks the rotating disc, so that rotation of the rotating disc is limited, the rotating action of the rotating disc and the limiting disc is limited by ingeniously utilizing the relative position relation of the limiting groove and the clamping groove, and therefore the mistaken touch prevention function is improved when the device is used or not used.

The utility model relates to a special fixing device of ejection tube belongs to ejection lifesaving device technical field, including fixed limiting frame, fixed limiting frame includes frame body, is fixed with two first limiting portions and two second limiting portions who set up oppositely on the frame body, two second limiting portions are located between two first limiting portions, still include connecting pin, the pin hole is seted up on the first limiting portion, and the connecting pin is used for passing through the pin hole and the middle hole of pulley assembly on the cabin wall board connection, the clamping groove is seted up on the second limiting portion, and the clamping groove is used for with the protruding of the upper clamp both sides on the upper end of ejection tube inner tube and connects, through two first limiting portions and the cooperation of pulley assembly, can limit the position of fixed limiting frame, make fixed limiting frame and pulley assembly, upper clamp fixed connection, because the position of pulley assembly on the cabin wall board is fixed, can limit the rotation around the axle of ejection tube inner tube, only one person can carry out the dismounting operation of nut, avoids the problem that the tacit understanding of two people cooperation is poor.
