The invention discloses a high-stability fabricated wallboard for interior decoration, and belongs to the technical field of wallboards. The wallboard comprises two first wallboards and a second wallboard; the two first wallboards are mutually attached together; the two first wallboards are fixedly connected through two tightening mechanisms; the two tightening mechanisms are symmetrically arranged up and down; the second wallboard is hinged to one side faces of the first wallboards; and a positioning mechanism is arranged in the second wallboard. According to the high-stability fabricated wallboard for interior decoration, by arranging the tightening mechanisms and a mounting mechanism, the two first wallboards are pulled to be away from each other, a certain gap exists between the two first wallboards at the moment, and a sliding rail block drives a fastening block to be tightly clamped in a fastening groove, so that the situation that the fixing effect of the first wallboards is affected due to loosening and disengaging of a sliding sleeve is avoided, and the fastening block can be controlled to be disengaged from the fastening groove; the sliding sleeve, check blocks and otherstructures are disassembled, so that parts are stored, and the cost is saved; and meanwhile, the two first wallboards can be disassembled, so that storage, installation and transportation are convenient.

The invention discloses intelligent frost-crack prevention pipeline connecting equipment for an industrial building of a large smart city. The intelligent frost-crack prevention pipeline connecting equipment comprises a first connecting sleeve and a second connecting sleeve which are both of a hollow cylindrical structure. The first connecting sleeve and the second connecting sleeve are sleeved with protective covers correspondingly, and heating grooves are spirally formed in the inner walls of the protective covers. Heating wires are arranged in the heating grooves. The protective covers are of inner layer and outer layer structures. The heating grooves are located in the inner walls of the inner layer structures of the protective covers. Cavities are formed between the inner layer and outer layer structures. Heat insulation sponges are bonded on the opposite end faces of the inner layer and outer layer structures correspondingly. Two segments of pipelines are mutually connected through the first connecting sleeve and the second connecting sleeve; and meanwhile the pipelines are heated through the protective cover and heating wire structure, frost cracking of the pipelines is avoided in the low-temperature state.

The invention discloses a large-capacity optical fiber cable joint cooling connection device, which comprises a plurality of optical fiber lines and a central housing arranged outside the optical fiber lines. An extrusion cavity is opened at the central axis inside the unit housing, and the extrusion cavity Thread grooves are provided at the parts of the inner cavity close to the end faces of both ends, and the extrusion chamber is screwed and connected with a stabilizing plug through the thread grooves. In the present invention, due to the threaded connection between the thread teeth and the thread, the connection and fixation at the two optical fiber line interfaces is facilitated, and the first sub-housing, the second sub-housing and the third sub-housing are used The mutual cooperation between them realizes the self-locking and locking between the first sub-housing, the second sub-housing and the third sub-housing. The connection between the cooling liquid and the outer wall of the unit shell is fully contacted to facilitate heat dissipation.

This application proposes a safety education indicating device, which includes a storage box with an open top, universal wheels distributed at the four corners of the bottom of the storage box, a sleeve assembly fixed inside the storage box, and a storage box that can be stored inside the storage box. The sign assembly, the sleeve assembly includes the No. 1 sleeve hinged on the No. 1 hinge block, and the No. 2 sleeve sleeved on the No. 1 sleeve. The No. 1 sign and the No. 2 sign on both sides of the No. 2 casing. In this application, through the setting of the storage box, the sleeve assembly supporting the sign assembly is designed to be hinged with the storage box, so that the sign assembly can be stored in the storage box, which greatly facilitates the installation of this kind of safety education indicator device. Portable so that teachers can carry it to each classroom for safety education.

A motorcycle provided with a head positioning device comprises the head positioning device. The head positioning device comprises a pull rod, a connecting rod, a lock body and a pull rod positioning device, wherein the bottom end of the pull rod is hinged to a motorcycle head, the lock body is fixed at the front end of the pull rod, a lock latch is arranged in the lock body, the connecting rod is fixed between two handles, a limiting block is arranged at the back end of the pull rod, and the pull rod positioning device comprises a fixing groove. The fixing groove is matched with the limiting block in shape. The pull rod passes two positions, when the pull rod passes the first position, the limiting block on the pull rod is clamped into the fixing groove, the lock latch extends out of the lock body, and the front end face of the lock latch abuts against the pull rod, and when the pull rod passes the second position, the lock latch retracts into the lock body, and the limiting lock breaks away from the fixing groove. The motorcycle is simple in structure, convenient to operate, safe and reliable, and a user can directly pull the pull rod downward in parking so as to achieve fixing of the head and a motorcycle body. In addition, when the motorcycle is required to be unlocked, the user can directly sit on the motorcycle or stand by the motorcycle to perform unlocking and does not need to crouch.
