The upper fixing plate and the lower fixing plate are provided with sliding grooves of the same structure, so that a worker can conveniently and rapidly fasten theupper mold and the lower mold through a pressing plate, the mold erecting efficiency is improved, molds of different sizes can be fixed, and the mold is convenient to disassemble.

The invention discloses a thumb wheel device capable of preventing a dialing wheel from dropping, which comprises a potentiometer with a switch, a panel, a dialing wheel, locking screws, a locking plate, fastening screws and a chassis, wherein the potentiometer with a switch is arranged on the side wall of the chassis by the fastening screws, a rotating shaft of a semicircular section of the potentiometer with the switch is used for being inserted into an inner semicircular hole at the center of the dialing wheel, the shaft is tightly locked with the dialing wheel through the locking screws, the locking plate is fixed to the dialing plate by fastening screws, the panel is provided with a slot, and the locking plate is embedded in the slot so as to prevent the dialing wheel from dropping from the rotating shaft of the potentiometer with the switch. According to the invention, the dropping problem of the dialing wheel of the thumb wheel device can be favorably solved, and the safe and reliable application of the thumb wheel device can be ensured. The thumb wheel device is suitable for controller products with harsh requirements to the dimension of the panel.

The invention discloses a novel hand-slip preventive brake pull rod for a railway truck. The novel hand-slip preventive brake pull rod comprises a hand-slip preventive guide frame, a pull rod head and a pull rod. Guide grooves are formed in the hand-slip preventive frame along the vertical direction of the hand-slip preventive frame, a carrier roll is arranged on the lower portion of the hand-slip preventive frame, a hand-slip preventive groove is formed in the pull rod head along the horizontal direction of the pull rod head, the pull rod head is arranged on the carrier roll and is connected with the hand-slip preventive guide frame by a hand-slip preventive pin which penetrates the guide grooves and the hand-slip preventive groove, and an end of the pull rod is fixedly connected with a tail groove of the pull rod head. The novel hand-slip preventive brake pull rod has the advantages that problems of clamping stagnation due to the fact that an existing hand brake pull rod for a railway truck slips out of an existing carrier roll at a sudden sectional change position of round steel and breakage of the existing hand brake pull rod due to fatigue and stress concentration at a sectional sudden change position of the tail of the existing hand brake pull rod can be effectively solved by the aid of the novel hand-slip preventive brake pull rod; the pull rod head still can be fixed onto the hand-slip preventive guide frame by the aid of the hand-slip preventive pin even if the tail of the pull rod is accidentally broken, a rod body of the integral pull rod head can be supported by the carrier roll without falling off, and accordingly the driving safety can be guaranteed.

The invention discloses a roll bearing chock clamping ring which comprises a clamping ring body I. One end of the clamping ring body I is connected with a clamping ring body II, and the other end of the clamping ring body I is connected with a clamping ring body III. The end of the clamping ring body II and the end of the clamping ring body III are connected through a lock bolt. A connecting plate for connecting the clamping ring body II and the clamping ring body III is arranged at the ends, connected through the lock bolt, of the clamping ring body II and the clamping ring body III. Under the combined action of the lock bolt and the connecting plate, the clamping ring is reliably and steadily assembled on a bearing chock. The connecting plate is taken as an added fastening measure, and after the lock bolt loses efficacy, the connecting plate plays a locking function and has an anti-dropping function. More importantly, when the connecting plate deforms and breaks, a warning effect can be directly and obviously achieved, point inspection and replacement are facilitated, safety is improved, and normal production with a rolling mill is guaranteed.

The invention discloses an anti-drop grounding clamp for power transmission lines, which comprises a clamp main body and a pair of splints. The clip body further includes a baffle for closing the clamping portion of the pair of splints, and the clamp body is provided with an adjustment mechanism for adjusting the position of the blocking portion of the baffle. The present invention solves the problem in the prior art that the ground wire is easily detached from the clamping portion of the pair of clamping plates by adopting the technical solution of adding a baffle plate for closing the clamping portion of the pair of clamping plates. Suitable for maintenance of transmission lines.

The invention discloses a crease roller for ink-free crease exercise book production, and belongs to the technical field of exercise book production devices. A mounting base is fastened to the side face of the lower end of a rack through screws, one side face of the mounting base is rotationally connected with a shaft rod through a bearing, one end of the shaft rod is fixedly connected with a crease concave roller, a groove is formed in the surface of the crease concave roller, a transverse rod is connected to the side face of one end of the rack in a sleeved mode, a conveying roller rotationally sleeves the surface of the transverse rod, and a clamping base is connected to the surface of the transverse rod in a clamped mode. According to the crease roller for ink-free crease exercise book production, a rotating angle adjusting function is achieved between a supporting plate and the transverse rod, therefore, the function of rapidly adjusting a gap between a crease convex roller and the crease concave roller is achieved, the crease roller can be suitable for crease folding of paper of different thicknesses, the application range of the crease roller is greatly widened, the crease convex roller, the crease concave roller and a conveying roller can be independently detached from the rack, and the later maintenance efficiency is greatly improved.
