Abstract
A saucer type round tube connecting column bolt comprises a screw rod, a round tube, a screw cap, limit antiskiding teeth and a nut. The screw nut is in a disc shape and is connected with the screw rod as a whole, the even limit antiskiding teeth are arranged on the outer edge of the screw cap, the nut is an outer circular internal threaded nut, the limit antiskiding teeth are arranged on the outer edge of the nut, the round tube is connected between the screw cap and the nut, the inner wall of the round tube is fixedly connected with the limit antiskiding teeth of the screw cap and the limit antiskiding teeth of the nut through compression joint, and saucer type fins are symmetrically arranged on the round tube. According to the saucer type round tube connecting column bolt, a screw, a bolt and the nut are connected through the connecting mode of the compression joint, and compared with a traditional casting or milling structure, the saucer type round tube connecting column bolt has the advantages of being easy to machine, stable in quality and capable of saving cost. The limit antiskiding teeth are adopted to reinforce the connecting tightness of the compression joint position, the bolt, the screw and the bolt column round tube are made of different materials, the intensity of threads and the cost of the bolt are controlled well, and the bolt can be mounted without tools.
Description
Technical field
The utility model relates to a kind of bolt, is specially a kind of dish-like pipe attachment post bolt.
Background technique
Attachment post bolt is widely used between the circuit board of electrical equipment multilayer, is support, connection and the fixing bolt of circuit board.
Traditional attachment post bolt is a metal integral, by casting or milling, forms.Casting machine shaping difficulty, tissue looseness, coarse grains, the inner defects such as shrinkage cavity and porosity, pore that easily produce, therefore, the mechanical property of foundry goods, particularly toughness are very low, and quality is unstable especially; Milling processing waste is large, the cycle is long, and manufacturing efficiency is very low.
Model utility content
The purpose of this utility model is: provide a kind of convenient processing, cost-effective dish-like pipe attachment post bolt.
In order to achieve the above object, the technological scheme adopting is: a kind of pipe attachment post bolt, comprises screw rod; It also comprises pipe, screw cap, spacing slideproof tooth and nut; Described screw cap is in the form of annular discs, connects as one with screw rod, and the outward edge of screw cap is provided with uniform spacing slideproof tooth; Described nut is cylindrical internal threaded nut, and the outward edge of nut is provided with spacing slideproof tooth; Described pipe is connected between screw cap and nut, and the spacing slideproof tooth of the inwall of pipe and screw cap and nut is fixedly connected with after by crimping; Described pipe is provided with symmetrical dish fin.
Adopt the beneficial effect of above-mentioned technology technological scheme to be: the Placement by crimping couples together screw rod, double-screw bolt and nut, relatively traditional casting or milling structure have that processing is simple, steady quality, cost-effective advantage, adopt spacing slideproof tooth to strengthen the connection tightness at crimping position; Screw rod, screw and double-screw bolt pipe adopt different materials, make the intensity of screw thread and bolt cost all obtain fine control; Bolt can be in order to avoid instrument installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dish-like pipe attachment post of the utility model bolt.
Fig. 2 is the plan view of Fig. 1.
In figure: 1-pipe, 2-screw cap, the spacing slideproof tooth of 2.1-, 3-screw rod, 4-nut, 5-dish fin.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of dish-like pipe attachment post bolt, comprises screw rod 3; It also comprises pipe 1, screw cap 2, spacing slideproof tooth 2.1 and nut 4; Described screw cap 2 is in the form of annular discs, connects as one with screw rod 3, and the outward edge of screw cap 2 is provided with uniform spacing slideproof tooth 2.1; Described nut 4 is cylindrical internal threaded nut, and the outward edge of nut 4 is provided with spacing slideproof tooth 2.1; Described pipe 1 is connected between screw cap 2 and nut 4, the inwall of pipe 1 with the spacing slideproof tooth 2.1 of screw cap 2 and nut 4 by being fixedly connected with after crimping; Described pipe 1 is provided with symmetrical dish fin 5.
This bolt is comprised of pipe 1, screw and nut 4, the outer diameter of screw cap 2 and nut 4 is identical with the inner diameter of pipe 1, screw cap 2 and nut 4 use fixtures are fixed in the two ends of pipe 1, together with by press-connection machine, pipe 1, screw cap 2 being crimped on nut 4; Pipe 1 inwall can deformation occur in crimping process and spacing slideproof tooth 2.1 is combined closely, and makes pipe 1, screw and nut 4 be linked to be an entirety; Dish fin 5 can be in order to avoid instrument construction bolt.
