Description

Adjustable U-bolt

Technical field

The utility model relates to technical field of fastening, especially a kind of adjustable U-bolt.

Background technique

Fastener is to be fastenedly connected with and apply extremely wide a kind of machine components, extensive using industry, including energy Source, electronics, electric appliance, machinery, chemical industry, metallurgy, mold, hydraulic etc. industry, various machinery, equipment, vehicle, ship, railway, Above bridge, building, structure, tool, instrument, chemical industry, instrument and articles etc., it can be seen that miscellaneous fastener, is Most widely used mechanical basic part, its feature are that description is various, and performance purposes is different, and standardization, seriation, Unitized degree is also high.Wherein, U-bolt, that is, U-bolts, criteria of right and wrong part, shape are U-shaped so also referred to as U-shaped spiral shell Bolt, both ends have screw thread that can be mainly used for the leaf spring of fixed tube such as water pipe or tablet such as automobile in conjunction with nut.

Existing U-bolt is generally made of the nut of the U-shaped part of TBE (threaded both ends) and end, and structure is fixed, and U-shaped part cannot It is adjusted according to practical fastening demand, applicability is poor, is badly in need of a kind of U-bolt for being able to carry out tightness specifications adjustment, example Such as Publication No. CN203756698U, the day for announcing is on August 6th, 2014, applies for the special of entitled " adjustable U-bolt " Benefit, which is divided into left half bolt and right half bolt for U-shaped part, and is fastened and adjusted by adjusting bolt, thus suitable Different fastening requirements are answered, but the U-bolt of the structure is only capable of being adjusted lateral tightness specifications, longitudinal U-shaped part length Or it is fixed, it can not solve the problems, such as poor for applicability, and lack matched support device on the connecting bottom board of bottom, it is to be tightened There are gaps between round tube and bottom plate, will affect fastening effect to a certain extent.

Utility model content

In order to overcome the shortcomings of that existing U-bolt regulation performance is poor, the utility model provides one kind and U-shaped spiral shell is adjusted Bolt is solved the problems, such as by adjusting the Split type bolt with adjustable connection by metal.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of adjustable U-bolt, including end Threaded section of U-shaped part, the nut being set on thread segment and connect both ends thread segment connecting bottom board, U-shaped part by left plate, Right side plate and the eccentric circular ring on top are constituted, and eccentric circular ring adjusts band by the metal at its both ends and connects with left plate and right side plate activity It connects, band is adjusted by metal, the tightness specifications of U-shaped part are adjusted.

Further, including metal adjusts band one end and is weldingly fixed on eccentric circular ring end, the other end be plugged in left plate and In the regulating tank opened up in right side plate, the telescopic adjustment in regulating tank.

Further, the location hole for plugging clamping screw is offered including regulating tank side.

Further, band is adjusted as the stainless steel band of uniformly distributed limit hole including metal.

Further, the triangle cushion block for being used to support object to be tightened is provided with including connecting bottom board both ends.

Further, the medial surface of U-shaped part is symmetricly set on including connecting bottom board both ends triangle cushion block.

The utility model has the beneficial effects that realizing U-bolt by the Split type U-shaped part for adjusting band connection by metal It is adjustable, to adapt to the object to be tightened of different size, improve applicability；The side plate and eccentric circular ring adjusted by positioning bolt into Row is locked, convenient and efficient；The triangle cushion block at connecting bottom board both ends is conducive to be supported cylindrical type object to be tightened, avoids pine It is dynamic, improve fastening effect.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the main view of the utility model；

Fig. 2 is the left view of the utility model.

1.U type part in figure, 11. left plates, 12. right side plates, 13. eccentric circular rings, 2. nuts, 3. connecting bottom boards, 4. metal tune Save band, 5. regulating tanks, 6. clamping screws, 7. limit holes, 8. triangle cushion blocks.

Specific embodiment

If Fig. 1 is the structural schematic diagram of the utility model, a kind of adjustable U-bolt is U-shaped including threaded section of end Part 1, the nut 2 being set on thread segment and the connecting bottom board 3 for connecting both ends thread segment, U-shaped part 1 is by left plate 11, right side plate 12 and the eccentric circular ring 13 on top constitute, eccentric circular ring 13 adjusts band 4 and left plate 11 by the metal at its both ends and right side plate 12 is living Dynamic connection, 5 side of regulating tank offer the location hole for plugging clamping screw 6, and 3 both ends of connecting bottom board, which are provided with, to be used to support The triangle cushion block 8 of object to be tightened, the triangle cushion block 8 at 3 both ends of connecting bottom board are symmetricly set on the medial surface of U-shaped part 1.In use, U-shaped part 1 is adjusted by way of stretching metal and adjusting band 4 according to the specification of object to be tightened, it is arc that metal, which adjusts band 4, Shape, one end are welded and fixed with eccentric circular ring 13, and the other end is plugged in regulating tank 5, if metal adjusts the pull-out of band 4, tightness specifications Become larger, if metal adjusts the retraction of band 4, tightness specifications become smaller, and are carried out after adjusting by the clamping screw 6 of 5 side of regulating tank Limit is fixed, and the triangle cushion block 8 at 3 both ends of connecting bottom board can be supported round tube to be tightened, avoid round tube and connecting bottom board 3 it Between gap cause round tube to loosen.

As shown in Fig. 2, metal, which adjusts 4 one end of band, is weldingly fixed on 13 end of eccentric circular ring, the other end is plugged in left plate 11 With in the regulating tank 5 that opens up in right side plate 12, metal adjusts the stainless steel band that band 4 be uniformly limit hole 7.It unclamps on regulating tank 5 Clamping screw 6, driven by way of stretching eccentric circular ring 13 metal adjust band 4, complete the adjustment of U-shaped 1 tightness specifications of part.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait Effect, but all will fall within the protection scope of the utility model.
