Abstract
A kind of outer connecting plate of pipe protection cap for the protection of petroleum casing pipe and all kinds of pipe ends, makes it be avoided damage in handling, transportational process.Including columnar cap body, it turns up to form crown in the cap body top sides edge, the cap body bottom is equipped with the back cover being inwardly indented, above-described cap body includes the cap body epimere, cap body stage casing and the cap body hypomere that are gradually retracted, the cap body stage casing and cap body hypomere outer wall are equipped with the shrapnel of longitudinal direction, it there are four the shrapnel is set, is placed equidistant with along cap body stage casing and cap body hypomere outer wall, the angle between shrapnel and outer wall tangent line is 20 40 °.Advantageous effect is, after shrapnel, protective cap is tightly combined with steel pipe, will not fall off in transportational process is loaded and unloaded and damaged and convenient for disassembly and assembly, and securely and reliably, using effect is preferable.
Description
Technical field
The utility model is mainly used for the protection of petroleum casing pipe and all kinds of pipe ends, makes it in handling, transportational process
It avoids damage to.
Background technology
Steel pipe easily damages pipe end in transportational process, in order to be protected to tube head, generally in pipe end
Protective cap is set with, past protection cap structure is too simple, with reference to closely, use does not come off easily in the process, and protecting effect is not
It is preferable.
Invention content
The utility model provides a kind of outer fastening of pipe protection cap precisely in order to solve deficiency of the prior art
Piece makes protective cap be tightly combined with steel pipe, convenient for disassembly and assembly.
In order to achieve the above object, the technical scheme adopted by the utility model is that：
A kind of outer connecting plate of pipe protection cap, it is characterized in that：Including columnar cap body, the cap body top sides are outside
It turns over to form crown, the cap body bottom is equipped with the back cover being inwardly indented, and above-described cap body includes the cap body being gradually retracted
Epimere, cap body stage casing and cap body hypomere, the cap body stage casing and cap body hypomere outer wall are equipped with the shrapnel of longitudinal direction, the bullet
There are four piece is set, it is placed equidistant with along cap body stage casing and cap body hypomere outer wall, the angle between shrapnel and outer wall tangent line is 20-40 °.
The telescopic chute protruded to bottom is formed between the back cover and cap body bottom, in the central part of the back cover
Position is equipped with dismounting hole.
The beneficial effects of the utility model are, after shrapnel, protective cap is tightly combined with steel pipe, in handling transportational process
In will not fall off and damaged and convenient for disassembly and assembly, securely and reliably, using effect is preferable.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the schematic top plan view of the utility model cross section.
In figure：1. cap body；2. crown；3. shrapnel；4. telescopic chute；5. back cover；6. dismount hole；7. cap body epimere；8. cap body
Stage casing；9. cap body hypomere.
Specific embodiment
By attached Fig. 1 and 2 it is found that the utility model includes columnar cap body 1,1 top sides of the cap body edge turns up to be formed
Crown 2,1 bottom of cap body are equipped with the back cover 5 being inwardly indented, and above-described cap body 1 is included in the cap body being gradually retracted
Section 7, cap body stage casing 8 and cap body hypomere 9, form the telescopic chute protruded to bottom between 1 bottom of the back cover 5 and cap body
4, dismounting hole 6 is equipped in the centre of the back cover 5.The cap body stage casing 8 and 9 outer wall of cap body hypomere are equipped with vertical
To shrapnel 3, the shrapnel 3 is made of elastic material, set altogether there are four, it is equidistant along cap body stage casing 8 and 9 outer wall of cap body hypomere
Setting, the angle between shrapnel 3 and outer wall tangent line is 20-40 °.After shrapnel 3, in use, only need to be along 3 tangent line of shrapnel
Direction rotates protective cap, you can is socketed in steel pipe light end, and because the elastic reaction of shrapnel 3 will not fall off.During dismounting, only
It needs still to rotate protective cap along 3 tangential direction of shrapnel, you can it is unloaded, it is convenient and strength-saving.
