The comb body has a plurality of evenly spaced teeth with a telescopically extensible spacing end tine that can extend to predetermined spacing distances for defining the perfect part for hair braiding.

The utility model discloses a preassembled nut anti-drop injection molding part, which comprises a preassembled nut, the preassembled nut enters a hole groove with an adaptive size arranged on the injection molding part through stamping, a plurality of latches are integrally formed on the periphery of the preassembled nut, the latches are distributed at intervals along the axial direction of the preassembled nut, an annular notch is formed between every two adjacent latches, and the preassembled nut is inserted into the hole groove. The annular notch is sleeved with a plurality of annular blocking layers, and the outer diameter of the outermost blocking layer is equal to the outer diameter of the annular notch. According to the injection molding part capable of preventing the preassembled nut from falling off, the clamping teeth which are arranged at intervals are integrally formed on the periphery of the preassembled nut, the annular notches are formed among the clamping teeth, the hollow flexible wrapping sleeve is sleeved at the annular notches firstly, and then the thin elastic cushion is nested at the annular notches, so that the wrapping sleeve on the inner side can be restrained to be in a relatively regular state, and the preassembled nut can be prevented from falling off. And the annular gap is completely filled outwards and is in contact with the inner wall of the hole groove, so that the contact friction force is further increased, and the problem that the preassembled nut falls off after swinging and shaking is avoided.

A manufacturing method of a horizontal rotary edge single chain scraper conveyor interval tooth wear-resistant sprocket, comprising the following steps: designing and calculating various important parameters of the sprocket; machining the sprocket body according to the obtained various important parameters of the sprocket; machining the movable lining plate; assembling and fixing the machined sprocket body and the movable lining plate through bolts; and finishing and heat treating the assembled sprocket assembly. The interval tooth wear-resistant sprocket manufactured by the method has a pitch at the sprocket chain nest which is 3 times the pitch of the round link chain, the interval tooth sprocket can be matched with the conventional round link chain, a variable pitch chain does not need to be designed separately, and the universality of the interval tooth sprocket is improved; the sprocket can provide a larger space to avoid interference with the guide scraper; the upper and lower tooth chain nests of the interval tooth sprocket and the upper surface of the lower tooth are subjected to local induction quenching treatment, and the movable lining plate is arranged on the upper surface of the lower tooth to enhance the wear resistance. The application also provides a horizontal rotary edge single chain scraper conveyor interval tooth wear-resistant sprocket.

The utility model relates to the technical field of dust falling equipment, and discloses an environment treatment atomization device which comprises a transverse pipe, a vertical pipe is fixedly installed in the middle of the transverse pipe, a spray head is fixedly installed at one end of the vertical pipe, an adjusting mechanism is arranged outside the transverse pipe, and an adjusting shaft moves outwards along a limiting pipe by controlling a pulling base. When the pulling seat is loosened, the limiting teeth can be embedded into the tooth ring under the action of the supporting spring, the fixing effect is achieved, the orientation of the spraying head can be conveniently adjusted through the device, and the later maintenance of the environment treatment atomization device is more convenient and faster; the fixing base is arranged outside the transverse pipe in a sleeving mode, the fastening bolt is adjusted to enable the supporting plate to fasten the transverse pipe, the device is easy to install and has a good fixing effect, and meanwhile a plurality of devices can be installed on a building or other objects at the same time.

The utility model relates to the technical field of nuts, and discloses a conical surface nut for an automobile, which comprises a nut body and a reinforcing threaded pipe fixedly mounted at the bottom of the nut body, a reinforcing block is fixedly sleeved above the outer side of the reinforcing threaded pipe, and the top of the reinforcing block is fixedly mounted at the bottom of the nut body. Through mutual cooperation of a protection plate, a positioning block, an inserting block and a T-shaped screw rod, a worker can clamp the nut conveniently through arrangement of the protection plate, so that the nut body is rotated, through arrangement of the T-shaped screw rod, the protection plate which is damaged after long-term use can be disassembled and replaced, damage to the nut body is avoided, and the use effect of the nut body is improved; through mutual cooperation of the moving plate, the threaded rod, the threaded sleeve, the worm gear, the worm and the rotary knob, the moving plate can be driven to move relatively, so that the limiting toothed rod moves relatively to be clamped with the screw rod, the anti-falling effect is improved when the nut is used, and the effect is better.

A closure for the lid of a travel mug has a first solid end and teeth with spacings therebetween at a second opposite end. The closure removably connects to the lid, with either the first end or the second end located near the periphery thereof. The closure slides radially relative to the lid. The lid has a peripheral opening for the passage therethrough of liquid from the mug when not obstructed. When the closure is connected to the lid and the second toothed end is aligned with the opening, liquid is able to flow through the opening and also through the spacings between the teeth. The teeth prevent passage of solid items. The closure is also movable relative to the lid to enable the user to completely block any flow through the opening, or to completely enable flow through the opening.

A mechanical lock nut retainment system enables accurate retention of a specified assembled position and torque of a lock nut. The system includes: a shaft having external threads on a threaded portion and external splines on a splined portion; a lock nut having internal threads that are threaded onto the threaded portion of the shaft, and the nut having spaced grooves extending around a circumference of the nut; and a lock washer having internal splines receivable on the splines of the splined portion of the shaft, and the washer having spaced teeth extending around a circumference of the washer. The spaced teeth of the washer are receivable in the spaced grooves of the nut.

A circular saw blade includes a circular plate-like body having a first side face, an opposite second side face, a periphery, and a central opening defining a center point, and rotatable in a cutting direction. A plurality of circumferentially-spaced teeth are separated by a plurality of gullets. The teeth include a plurality of first beveled teeth with a top face beveled radially inward in a first direction, a plurality of second beveled teeth with a top face beveled radially inward in an opposite second direction, and a plurality of unbeveled teeth. The first beveled teeth, second beveled teeth, and unbeveled teeth are arranged in an alternating top bevel+raker pattern. Each second beveled tooth is disposed radially inward toward the central opening from each first beveled tooth by a first drop distance.
