Abstract

The utility model relates to a pipe saddle which comprises an upper pipe saddle and a lower pipe saddle. Through holes are formed both in two sides of the upper pipe saddle and two sides of the lower pipe saddle. The upper pipe saddle and the lower pipe saddle are connected by the fact that nuts which are matched with the bolts are enabled to be screwed in the bolts which penetrate through the through holes. Annular protrusions which are used for preventing the bolts from rotating are arranged around the through holes of the lower pipe saddle. The section shape of a hollow area inside each annular protrusion is matched with the section shape of the head portion of each bolt, and the section of the head portion of each bolt is of a polygon shape. Due to the fact that the protrusions are arranged beside the through holes of the lower pipe saddle, after the bolts are inserted in the through holes of the lower pipe saddle, the head portions of the bolts are clamped inside the annular protrusions, the head portions of the bolts can not rotate, and so that the whole bolts are fixed not to move. Under such a condition, the nuts only need to be rotated, other tools such as wrenches do not need to fix the bolts, and the nuts can be screwed into the bolts. The pipe saddle is simple in structure and convenient to use.

Description

A kind of pipe saddle

Technical field

The utility model relates to fluid shunt conduit link technical field, relates in particular to a kind of pipe saddle device.

Background technique

Pipe saddle (claim again divide water a saddle) is for building the special part that arm, family pipe are installed in perforate on the PVC-U pipeline.Its essential structure is two semicircle pipe collars that can be fastened on the pipeline, arranges at top semicircle pipe collar variously to punch and be connected facility, can be at pipeline under the anhydrous or band water condition perforate pick out arm, family pipe.Be generally the serial special product of produce in factory, as the vertical water stop bolt of boring hole with water, rotary pipe saddle etc.Pipe knee roll of the prior art draw together housing (or claim valve body), on manage saddle and following pipe saddle etc., on to manage saddle all be to be connected by screw rod with following pipe saddle.The pipe saddle is installed in underground, because there is certain error in the water pipe external diameter in manufacture process, need stay certain clearance between the above pipe saddle of institute and the following pipe saddle, pipeline could be clamped by tightening with the screw rod nut engaged afterwards.Another is brought in and prevents that whole screw rod from following nut rotation and rotate often to need to use the spanner standing screw in the process of fastening nut, especially the hole under, when the less occasion of wall or space is carried out such installation, can bring operational inconvenience to the staff thus.

The model utility content

Technical problem to be solved in the utility model provides a kind of simple in structure, a kind of pipe saddle of being easy to fitting operation.

The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of pipe saddle, comprise pipe saddle and following pipe saddle, described both sides of going up pipe saddle and following pipe saddle are provided with through hole, described pipe saddle and the following pipe saddle gone up is connected by being screwed into the bolt that passes described through hole with the suitable nut of bolt, be provided for preventing the annular protrusion of bolt rotation around each through hole of described pipe saddle down, the sectional shape in the boring zone of described annular protrusion and described bolt head sectional shape are suitable, and described bolt head cross section is polygonal.Bolt is by head and screw rod (having an externally threaded cylindrical body) class fastening piece dimerous.

The beneficial effects of the utility model are: the nut rotation is being twisted in the process of bolt one end, if the other end of bolt, be the unfixed words of an end at bolt head place, bolt integral body is easy to follow nut and rotates together, so just makes nut be difficult on the bolt and advances along hand of spiral.Because the through hole next door of pipe saddle is provided with projection down, after the through hole of pipe saddle under the bolt reeve, bolt head is stuck in the annular protrusion the inside, bolt head can not be rotated, and then the bolt overall fixed is motionless, in this case, only need the rotation nut not need to use in addition other instrument such as spanner with bolt, just nut can be screwed into bolt, this apparatus structure is simple, and is easy to use.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, described bolt head cross section is Hexagon or square.

Further, the height of described projection is lower than the height of described bolt head.

Adopt the beneficial effect of above-mentioned further scheme to be, the height of projection is lower than the height of described bolt head, saves the material of making projection, reduces space hold.After the through hole of pipe saddle, bolt head had part to expose from the annular protrusion the inside under bolt inserted, and when needs are dismantled, conveniently bolt was taken out from the through hole the inside.。

Description of drawings

Fig. 1 is the structural representation of the utility model pipe saddle;

Fig. 2 is half part-structure schematic representation of pipe saddle under the utility model;

Fig. 3 is the plan view of Fig. 2.

In the accompanying drawing, the list of parts of each label representative is as follows:

1, following pipe saddle, 2, on manage saddle, 3, nut, 4, bolt, 5, bolt head, 6, projection.

Embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.

Fig. 1 is the structural representation of the utility model pipe saddle, as shown in Figure 1, a kind of pipe saddle, comprise pipe saddle 2 and following pipe saddle 1, described both sides of going up pipe saddle 2 and following pipe saddle 1 are provided with through hole, described pipe saddle 2 and the following pipe saddle 1 gone up is connected by being screwed into the bolt 4 that passes described through hole with the suitable nut 3 of bolt 4, and each through hole of described pipe saddle 1 down is provided for preventing the annular protrusion 6 of bolt rotation on every side.Sectional shape and described bolt head 5 sectional shapes in the boring zone of described annular protrusion 6 are suitable, and bolt head 5 can be put the inside, boring zone of annular protrusion 6 into.Described bolt head cross section is Hexagon, and the sectional shape in the boring zone of annular protrusion 6 also is Hexagon.The bolt head cross section can be other polygonal, for example quadrilateral or pentagon etc.

Fig. 2 is half part-structure schematic representation of pipe saddle under the utility model, and Fig. 3 is the plan view of Fig. 2.In conjunction with Fig. 2 and shown in Figure 3, hexagon bolt head 5 embeds annular protrusion 6 boring zones, and bolt head 5 can not left-right rotation because of stopping of projection 6.The height of described annular protrusion 6 is lower than the height of described bolt head, and after the through hole of pipe saddle, bolt head had part to expose from the annular protrusion the inside under bolt inserted, and when needs are dismantled, conveniently bolt was taken out from the through hole the inside.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
