The utility model discloses a pole piece compression roller and a pole piece rolling device, and relates to the technical field of battery production, the pole piece compression roller comprises a compression roller body and at least two first scale marks; the compression roller body is used for carrying out rolling operation on the battery pole piece; an adhesive tape attaching area arranged in a surrounding mode in the circumferential direction is arranged on the peripheral rolling face of the pressing roller body, and the adhesive tape attaching area is used for attaching a thickening adhesive tape. The first scale line is arranged on the peripheral rolling surface, extends in the axial direction of the compression roller body and penetrates through the adhesive tape attaching area; the at least two first scale marks are arranged at intervals in the circumferential direction of the pressing roller body. According to the scheme, the at least two first scale marks arranged on the compression roller body provide a complete visual positioning reference basis for the attachment operation of the thickened adhesive tape, and an operator can check whether the thickened adhesive tape which is being attached has an axial deviation problem or not by means of the first scale marks entering a visual field range in the attachment process; and the continuous alignment of the thickened adhesive tape in the surrounding and attaching process is realized, so that the attaching precision is improved.

The utility model relates to the technical field of theft prevention, and particularly discloses a stay wire anti-theft device which comprises a lock body, a spring bolt and a stay wire adjusting assembly, the lock body is fixedly arranged on a first anti-theft object, a locking cavity is vertically formed in the lock body, a sliding cavity and an installation cavity are transversely formed in the two sides of the locking cavity in a penetrating mode respectively, and the sliding cavity and the installation cavity are arranged in an up-down staggered mode. The end portions of the two anti-theft objects penetrate through the end face of the locking cavity, a spring bolt is installed in the installation cavity in a matched mode, one end of the spring bolt is fixed to a second anti-theft object locked with the first anti-theft object in a matched mode, and the other end of the spring bolt can penetrate through the installation cavity and extend into the locking cavity; the stay wire adjusting assembly comprises a limiting block, a stay wire, a pushing block and a clamping block, the limiting block is clamped at the opening of the sliding cavity, one end of the stay wire penetrates through the limiting block and then extends out to be connected with the pushing block, and the other end of the stay wire is connected with the driving mechanism. According to the anti-theft device, the first anti-theft object and the second anti-theft object can be mutually locked or detached, and locking or unlocking of the device is achieved by controlling the pull wire through the driving mechanism.

The utility model discloses a kind of stable drive structure of hanger for electroplating production line, it is related to electroplating equipment technical field, include drive assembly, drive assembly is installed on electroplating production line, drive assembly includes transmission chain and the drive gear for driving transmission chain movement, the outside of transmission chain is fixedly provided with multiple racks, multiple racks are continuously and aligned, each rack has array distribution tooth profile structure, tooth profile structure is located rack far from transmission chain side;Hanger body, hanger body is slidably installed on electroplating production line, the three pawls of each ratchet of the scheme are staggered and size decreases, can be simultaneously engaged with the three tooth profile structures adjacent on rack, through multiple teeth contact dispersion backlash error, simultaneously, the gradient design of pawl height and width can adapt to the slight deformation of rack, ensure that there is no obvious gap in meshing process, effectively avoid displacement deviation when hanger moves, reduce the risk of jamming or overlapping.

The utility model relates to the technical field of pipe fitting sealing connection, and discloses a sealed and fixed threaded type clamp flange structure which is used for sealing and connecting pipelines and comprises a clamp pipeline assembly, a threaded type clamp fixing ring and a sealing backing ring. The clamp pipeline assembly is provided with an inner taper annular face, the threaded clamp fixing ring is provided with a V-shaped taper annular face and a thread, and the end of the clamp pipeline assembly is provided with a thread matched with the thread. The sealing backing ring is provided with a taper annular face matched with the inner taper annular face. And the hoop pipeline assembly is in threaded connection with the threaded type hoop fixing ring through threads. According to the sealed and fixed threaded type clamp flange structure, the inner face and the outer face of the flange connector are designed to be the taper annular faces, the extrusion area of the clamp assembly and the flange connector is increased, stress concentration is reduced, and it can be guaranteed that the flange connector and the sealing ring are effectively meshed together; the sealing performance of the pipeline is ensured.

The present application relates to a precast pile plug-in lock joint, comprising: an upper sleeve, a bottom end of which is provided with a plug rod, a bottom end of the plug rod is provided with a first connecting structure, an outer circumferential wall of the plug rod is provided with an outer lock piece capable of being elastically deformed in a radial direction, the outer lock piece is provided with a second connecting structure and a first combining surface; a lower sleeve, a top end of which is provided with an opening for inserting the plug rod, a bottom of the lower sleeve is provided with an inner lock piece capable of being elastically deformed in a radial direction, an inner wall of the inner lock piece is provided with a third connecting structure matched with the first connecting structure and a second combining surface matched with the first combining surface, and an inner wall of the lower sleeve is provided with a fourth connecting structure matched with the second connecting structure; after the plug rod is inserted into place, the first combining surface is attached to the second combining surface, so as to form double self-locking between the second connecting structure and the fourth connecting structure and between the third connecting structure and the first connecting structure when being pulled.
