Description

Multifunctional U-shaped bolt

Technical Field

The utility model belongs to the technical field of the bolt, concretely relates to multi-functional U type bolt.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

In chinese patent with publication number CN203926297U, a multifunctional U-shaped bolt is disclosed, comprising: the connecting screw rod is provided with a plurality of second threads, the connecting screw rod is screwed in the connecting hole of the U-shaped bolt, and a connecting ring is arranged on the central line of the U-shaped bolt.

However, the above technical solution has the following drawbacks: when fixing different spare parts, the interval between two bolt holes of seting up on the spare part is different for spare part is different at every turn and all needs the bolt of different models, makes the suitability of bolt not strong.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multi-functional U type bolt aims at solving the not strong problem of multi-functional U type bolt suitability among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a multi-functional U type bolt, includes the double-screw bolt that the symmetry set up, be provided with the screw thread on the double-screw bolt, the upper portion of double-screw bolt is provided with hollow sleeve, hollow sleeve's inside sliding connection has the carriage release lever, the expansion end and another double-screw bolt fixed connection of carriage release lever.

In order to make this multi-functional U type bolt have the effect of conveniently cleaing away the dust on spare part surface, as the utility model relates to an it is preferred, set up flutedly on the hollow sleeve.

Preferably, the groove is an arc-shaped groove.

In order to make this multi-functional U type bolt have the effect that prevents the hollow sleeve and damage, as the utility model relates to an it is preferred, the hollow sleeve outside is provided with the elastic component.

Preferably, the elastic member is a rubber pad.

In order to make this multi-functional U type bolt have the effect of fastening two spare parts, as the utility model relates to an it is preferred, threaded connection has the nut on the double-screw bolt.

In order to make this multi-functional U type bolt have the not hard up effect of nut, conduct the utility model relates to an it is preferred, be provided with the cover on the nut and establish the outside packing ring of double-screw bolt.

Preferably, the stud is made of iron.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this multi-functional U type bolt slides in hollow sleeve inside through the carriage release lever, drives two double-screw bolts and keeps away from or be close to each other to change the distance between two double-screw bolts, thereby make the bolt hole interval of seting up on two spare parts can all be fixed regardless of how big or small, make the adaptability of bolt stronger.

2. This multi-functional U type bolt through setting up the recess, when two spare parts of fastening, can hold the double-screw bolt earlier, strikes off the dust on the spare part with the border department of recess, and the dust of being scraped off does not get into recess department, clears away and finishes, strikes hollow sleeve with the hand for the dust of recess the inside falls into in the garbage bin.

2. This multi-functional U type bolt through setting up the rubber pad for avoid being knocked badly when knocking hollow sleeve.
