Abstract

The utility model relates to a machine parts technical field especially relates to a hookup screw rod. Including the short screw rod of screw head, a plurality of with be used for carrying out the coupling pin that is connected with screw head and short screw rod, the screw head tail end is equipped with the end pin hole, and short screw rod top is equipped with first pinhole, and coupling pin passes the end pin hole and screw head and weak point screw rod are connected to first pinhole. This hookup screw rod's simple structure, screw rod length can prolong wantonly to satisfy the actual need, avoided the narrow and small and appearance of the long bolt unserviceable problem that leads to in space.

Description

A kind of screw connection
Technical field
The utility model relates to component of machine technical field, particularly relates to a kind of screw connection.
Background technique
Bolt: mechanical parts, the cylindrical threaded fastening piece of adapted nut.By head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.
The frequency of utilization of bolt is very high, but under certain conditions, due to narrow space, can not hold sufficiently long bolt, therefore space and demand cause contradiction.
Summary of the invention
The purpose of this utility model is the awkward problem using existence in order to solve current bolt or screw rod when sky is narrow and small, provides a kind of screw connection.
In order to reach above-mentioned model utility object, the utility model by the following technical solutions:
A kind of screw connection, comprise screw head, several short screws and the attachment pegs for screw head and short screw being carried out being connected, screw head tail end is provided with pin hole, and short screw top is provided with a pin-and-hole, and screw head is connected with short screw with head pin-and-hole through pin hole by attachment pegs.
As preferably, described screw head tail end is provided with sunk key or embedded groove, and short screw is provided with the embedded groove or sunk key that match with it.
As preferably, the cross section of described sunk key or embedded groove is square.
As preferably, screw head tail end offers the working position of plane, and pin hole is located at this working position place, short screw top be provided with match with working position and be fitted in the laminating position that working position place forms with it complete screw rod, head pin-and-hole is located at laminating position place.
As preferably, described attachment pegs be positioned at inner pin hole or head pin-and-hole Spielpassung, attachment pegs be positioned at peripheral head pin-and-hole or pin hole interference fit.
As preferably, described screw head tail end offers some gaps and symmetrical working position; Short screw top hollow, and be provided with screw head tail end embed after and working position match and be fitted in laminating position working position being formed with it complete screw rod.
Compared with prior art, beneficial effect is the utility model: structure is simple, and spiro rod length can extend arbitrarily, thus meets actual demand, avoids narrow space and the appearance of the non-serviceable problem of long bolt that causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
In figure: 1 screw head, 2 short screws, 3 attachment pegs, 4 pin holes, 5 pin-and-holes, 6 sunk keys, 7 embedded grooves, 8 working positions, 9 laminating positions.
Embodiment
Below by specific embodiment, explanation is further described to the technical solution of the utility model.
Embodiment:
A kind of screw connection, as shown in Figure 1, comprise screw head 1, several short screws 2 and the attachment pegs 3 for screw head 1 and short screw 2 being carried out being connected, screw head 1 tail end is provided with pin hole 4, short screw 2 top is provided with a pin-and-hole 5, and screw head 1 is connected with short screw 2 with head pin-and-hole 5 through pin hole 4 by attachment pegs 3.
As depicted in figs. 1 and 2, described screw head 1 tail end is provided with sunk key 6 or embedded groove 7, and short screw 2 is provided with the embedded groove 7 or sunk key 6 that match with it, and the cross section of described sunk key 6 or embedded groove 7 is square, and sunk key 6 is cuboid shape.
As depicted in figs. 1 and 2, screw head 1 tail end offers the working position 8 of plane, pin hole 4 is located at this working position 8 place, short screw 2 top be provided with match with working position 8 and be fitted in the laminating position 9 that working position 8 place forms with it complete screw rod, head pin-and-hole 5 be located at laminating position 9 place.
Described attachment pegs 3 and the pin hole 4 or head pin-and-hole 5 Spielpassung that are positioned at inside, attachment pegs 3 and the head pin-and-hole 5 or pin hole 4 interference fit that are positioned at periphery.
Described screw head 1 tail end offers some gaps and symmetrical working position 8; Short screw 2 top hollow, and be provided with screw head 1 tail end embed after and working position 8 match and be fitted in the laminating position 9 working position 8 being formed with it complete screw rod.
