Description

Jacket structure convenient for twisting double-end tooth bar

Technical Field

The utility model relates to a fastening connection technical field, more specifically relate to a jacket structure convenient to double-end tooth strip is twisted and is moved.

Background

The thread bar is also called a screw rod, is a rod body with threads distributed on the outer surface and is mainly used for connecting components. The double-head thread strip has threads at two ends and a polished rod structure in the middle as the name suggests.

Prior art, double-end dental stripe overall structure becomes cylindricly, and it is when assembling with other parts, can only clamp the middle body of rod position of dental stripe through the spanner and move the dental stripe in order to twist, however because the intermediate position of dental stripe still is polished rod formula structure for cylindricly simultaneously, leads to the spanner to skid easily, consequently not only wastes time and energy when screwing up double-end dental stripe, but also hardly screws up and targets in place. There is room for improvement in prior art double-ended dental strips.

SUMMERY OF THE UTILITY MODEL

The utility model provides a to prior art not enough, the utility model provides a jacket structure convenient to double-end rack is twisted and is moved through this jacket structure, can effectively screw up double-end rack, but also labour saving and time saving.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a jacket structure convenient to double-end tooth strip is twisted, characterized by: the clamping sleeve is formed by splicing a first half sleeve body and a second half sleeve body, the first half sleeve body is provided with an assembling groove, the second half sleeve body is provided with an assembling strip matched with the assembling groove, and the clamping sleeve is provided with a hexagonal edge for clamping a wrench.

Preferably, the present invention is further configured such that the hexagonal edges have a plurality of sections and extend the axial alignment of the jacket and the diameter between each section of the hexagonal edges is different.

Preferably, the present invention is further configured such that the hexagonal edge has three segments.

As preferred, the utility model discloses further set up to, the assembly groove is the cooperation of T shape structure with the assembly strip.

Preferably, the utility model discloses further set up as, have along pressing from both sides the spacing strip that cover axial extension and be used for circumference spacing on the inner wall that presss from both sides the cover.

Compared with the prior art, the utility model has the advantages that: when the double-end toothed bar wrench is used, the clamping sleeve is assembled on the polished rod section of the double-end toothed bar, and then the wrench is clamped on the hexagonal edge of the clamping sleeve, so that an operator can conveniently screw the double-end toothed bar; after the double-end dental strip is screwed up, the first half-sleeve body and the second half-sleeve body can be separated, and meanwhile, the first half-sleeve body and the second half-sleeve body can be detached from the double-end dental strip, so that the novel screw is convenient to use and can be stably screwed up.

fig. 2 is an axial view of the jacket provided in the present embodiment.

Detailed Description

The jacket structure for facilitating the screwing of the double-end rack of the present invention will be further described with reference to fig. 1 to 2.

The utility model provides a double-end dental strip convenient to installation, includes dental strip body 1, and the both ends of dental strip body 1 are screw thread section 11, and the position between two screw thread section 11 is polished rod section 12. The method is characterized in that: the double-end tooth bar further comprises a clamping sleeve 2, the clamping sleeve 2 is circumferentially limited and can be axially movably assembled on the polished rod section 12, the clamping sleeve 2 can be detached relative to the polished rod section 12, and a hexagonal edge 21 for clamping a wrench is arranged on the clamping sleeve 2.

Based on the structure, when the tooth bar connecting device is used and the tooth bar body needs to be assembled on the connecting component, the spanner is clamped on the hexagonal edge 21 of the jacket 2 to rotate the tooth bar, so that the tooth bar can be obviously and conveniently screwed on the connecting component; when the connecting part is assembled on the tooth bar, the wrench can be clamped on the tooth bar to position the tooth bar, so that the tooth bar is prevented from rotating along with the connecting part, and the tooth bar and the connecting part can be effectively screwed; the clamping sleeve 2 can axially move on the tooth bar body, so that when a wrench clamps the clamping sleeve 2, the position of the clamping sleeve 2 can be adjusted, and the wrench can be clamped on the clamping sleeve 2 at the optimal position; the jacket 2 can be removed from the dental strip before and after use, avoiding the jacket 2 from interfering with the normal use of the dental strip. In conclusion, the invention has the characteristics of convenient use, high flexibility and effective tightening of the dental strip body.

Specifically, the hexagonal edges 21 have a plurality of stages and are arranged along the axial direction of the jacket 2, and the diameters of the hexagonal edges 21 are different from one stage to another. With the structure, the jacket 2 can be clamped by wrenches with different sizes and models, so that the flexibility and the convenience of the use of the invention are obviously improved. In this embodiment, the hexagonal edge 21 has three segments, and in practical applications, the hexagonal edge 21 can be more than three segments according to practical requirements.

The jacket 2 is formed by splicing a first half jacket body 22 and a second half jacket body 23, the first half jacket body 22 is provided with an assembling groove 221, and the second half jacket body 23 is provided with an assembling strip 231 matched with the assembling groove 221. The mounting groove 221 and the mounting bar 231 are matched in a T-shaped structure. During assembly, the first half sleeve body 22 is attached to the polished rod segment 12, then the assembly strip 231 of the second half sleeve body 23 is butted with the assembly groove 221 of the first half sleeve body 22, and the assembly strip 231 is pushed from one end of the first half sleeve body 22 to the other end of the first half sleeve body 22, so that the assembly strip 231 can be loaded into the assembly groove 221, and meanwhile, the assembly of the first half sleeve body 22 and the second half sleeve body 23 on the dental strip body is completed; when the dental floss is disassembled, only the first half sleeve body 22 or the second half sleeve body 23 needs to move along the axial direction of the dental floss body alone, so that the assembling bar 231 slides out of the assembling groove 221, the structure is simple, the operation is convenient, and the assembling stability is high.

The polished rod section 12 is provided with a limiting groove 121 which moves along the axial direction of the dental floss body, and the inner walls of the jacket 2, namely the inner walls of the first half-sleeve body 22 and the second half-sleeve body 23, are provided with a limiting strip 24 which is matched with the limiting groove 121, so that the structure can limit the rotation of the jacket 2 on the dental floss.
