The utility model discloses a protective device for constructional engineering, and belongs to the technical field of constructional engineering. A protective device for constructional engineering comprises a first stand column and a second stand column used in cooperation with the first stand column, the first stand column is provided with a cavity structure, a winding shaft is arranged in the cavity structure, a protective net is arranged on the periphery of the winding shaft, a connecting rod is installed at the end, located outside, of the protective net, and the connecting rod is connected with the winding shaft. A positioning seat is installed at the end, located outside, of the winding shaft, and a locking piece used in cooperation with the positioning seat is arranged on the first stand column. According to the protection device, through cooperation of the first stand column and the second stand column, a protection system capable of being flexibly unfolded and stored is constructed, the protection function can be rapidly achieved only by pulling the protection net out of the cavity structure, matching the connection rod with the connection base on the second stand column and locking through the locking piece, and the protection device is convenient to use and high in practicability. And the actual requirements that the construction site layout and the construction progress change frequently are effectively met.

The present invention relates to the technical field of medical devices, and specifically to a ligation clamp, comprising: a female plug body, on which a connected access channel and a ligation groove are provided, and a fine pipe can enter along the access channel and be accommodated in the ligation groove; a male plug body, which is plugged and matched with the female plug body to be movably accommodated in the ligation groove and the access channel, the head shape of the male plug body matches the ligation groove, and the head of the male plug body abuts against the side wall of the ligation groove to ligate the fine pipe; and a locking member, which is used to lock the male plug body at a predetermined position of the female plug body so that the head of the male plug body abuts against the side wall of the ligation groove. By dividing the ligation clamp into two parts, the female plug body and the male plug body, in the process of ligating the fine pipe, the ligation clamp does not need to be deformed, successfully avoiding the characteristic of the degradable magnesium alloy that is not easy to deform, so that the fine pipe can be effectively clamped.

The chair seat height adjusting mechanism comprises two chair legs which are in bilateral symmetry and a chair seat which is detachably connected between the two chair legs, limiting parts are arranged on the left side and the right side of the chair seat, each limiting part is of a semi-enclosed structure with an opening in the front side, each limiting part comprises a limiting groove formed in the middle in a sunken mode, and the limiting grooves are formed in the left side and the right side of the chair seat. The chair seat is attached to the chair legs through the limiting grooves; a positioning structure is arranged between the limiting groove and the chair leg, the positioning structure comprises a clamping head and a clamping groove, the clamping head is arranged in one of the limiting groove and the chair leg, and the clamping groove is formed in the other one of the limiting groove and the chair leg; when the chair seat is connected to the chair legs, the chair legs are clamped into the limiting grooves through the openings in the front sides of the limiting parts, and the clamping heads are clamped into the clamping grooves, so that the chair seat and the chair legs are relatively fixed. According to the chair seat height adjusting mechanism, the chair seat and the chair legs are fixed in a clamping fit mode, so that the chair seat is convenient to mount and dismount for height adjustment, positioning is firm and reliable, and the safety of the chair is good.

An opening locking device of a switch belongs to the technical field of low-voltage electric appliances. The switch comprises an operating mechanism and an opening locking device, the operating mechanism comprises a pair of side plates which are arranged at an interval, and an opening half shaft is also rotationally arranged between the pair of side plates; the switch-off locking device is characterized in that the switch-off locking device comprises a support, a sliding plate, a lock cylinder and a key, the support is fixedly arranged, the sliding plate is slidably arranged, and the lock cylinder is installed on the support; when an opening locking action is carried out, the key drives the lock cylinder to act, the lock cylinder drives the sliding plate to slide, and the driving end of the sliding plate pushes the first pushing end of the opening half shaft to rotate, so that the opening half shaft is locked at an opening position. The method has the advantages that the operation steps are simplified, and the opening locking operation is simpler and more convenient.
