Abstract
A sleeve used for the fast installation of a double end stud comprises a sleeve body and a propping ball. A square mortise is formed at one end of the sleeve body; a screwed hole which corresponds to the double end stud is formed at the other end of the sleeve body; the square mortise and the screwed hole have the same axis as the sleeve body; the propping ball is embedded in the bottom center of the screwed hole of the sleeve body; and the embedding depth is larger than the radius of the propping ball and is smaller than the diameter of the propping ball. The sleeve can be matched with an impact wrench, a ratchet wrench, or a torque spanner. When the sleeve is in use, a square tenon of the wrench is inserted in the square mortise of the sleeve body, the screwed hole formed at the other end of the sleeve body is in connection with threads on the non-placing side of the double end stud, the propping ball embedded in the bottom center of the screw thread of the sleeve body contacts with the top end of the non-placing side of the double end stud, the rotation of the wrench is utilized to enable the double end stud to rotate, and finally . the installation of the double end stud is finished. The installation speed is fast, the efficiency is high, and the damage to the threads of non-placing side of the double end stud is not caused.
Description
Technical field
The utility model relates to a kind of mechanical links erecting tools, particularly a kind of studs Fast Installation sleeve.
Background technology
Studs connects and to be applicable to the occasion that can not adopt Bolt Connection on the structure, and one of for example coupled too thick should not make through hole.At present, mainly be studs to be installed with hand-operated tools, earlier, use the spanner nutting then with two nuts and tightly on studs, studs one end is entered in coupled that should not make through hole.The shortcoming of its existence is: the install operation process complexity, and speed is slow, and efficient is low, easily causes the non-damage of inserting the side screw thread of studs.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming that existing hand-operated tools is installed studs, and a kind of studs Fast Installation sleeve that can be used with impact wrench is provided.
The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of studs Fast Installation sleeve, it is characterized in that forming and comprise the sleeve body and the decorative pearl on top of an official cap, the described sleeve body one end side of having mortise, the other end has the screwed hole corresponding with studs, side's mortise and screwed hole are all coaxial with sleeve body, the described decorative pearl on top of an official cap embeds sleeve body screwed hole bottom centre, and insert depth is greater than the radius of the decorative pearl on top of an official cap and less than the diameter of the decorative pearl on top of an official cap.
The beneficial effects of the utility model are as follows: this sleeve is suitable for cooperating impact wrench, ratchet spanner or torque spanner to use, square tenon with spanner during use is inserted in the square mortise of sleeve body one end, the screwed hole of the sleeve body other end is threaded with the non-side of inserting of studs, the decorative pearl on top of an official cap that embeds sleeve body screwed hole bottom centre touches the non-top of inserting side of studs, utilize the rotation of spanner to drive the studs rotation, and then finish the installation of studs, installation rate is fast, the efficient height can not cause the non-damage of inserting the side screw thread of studs.The effect of the decorative pearl on top of an official cap has two, one, solves the not enough problem of sleeve body screwed hole bottom hardness (it is big that the hardness of the decorative pearl on top of an official cap is easy to the hardness that is processed into than sleeve body screwed hole bottom), and the screwed hole bottom is taken out of studs is bonding when avoiding sleeve body to withdraw from; The 2nd, can judge at the non-impression of inserting the side top of studs whether studs is in place by the decorative pearl on top of an official cap.
Description of drawings
Fig. 1 is the utility model studs Fast Installation sleeve overall structure vertical profile schematic diagram.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.But the utility model is not limited to given example.
As shown in Figure 1, the composition of the utility model studs Fast Installation sleeve comprises the sleeve body 1 and the decorative pearl on top of an official cap 2, the described sleeve body one end side of having mortise 11, the other end has the screwed hole corresponding with studs 12, side's mortise 11 and screwed hole 12 are all coaxial with sleeve body 1, the described decorative pearl on top of an official cap 2 embeds the bottom centre of sleeve body screwed holes 12, and insert depth is greater than the radius of the decorative pearl on top of an official cap and less than the diameter of the decorative pearl on top of an official cap.Among the embodiment, sleeve body and studs all adopt the manufacturing of No. 45 ordinary steel materials, and the decorative pearl on top of an official cap is a plain ball, and decorative pearl on top of an official cap diameter is about 3/4ths of screwed hole diameter.The telescopiny of the decorative pearl on top of an official cap is as follows: in bottom centre's boring of screwed hole 12, the diameter in this hole is slightly less than the diameter of the decorative pearl on top of an official cap and the radius that the degree of depth is slightly larger than the decorative pearl on top of an official cap, and the decorative pearl on top of an official cap is pressed into this hole, makes the two interference fit.
In embodiment as shown in Figure 1, in order to save material and to make sleeve body specious, further feature is: an end of sleeve body 1 corresponding screwed hole 12 is conical.
Claims (2)
1, studs Fast Installation sleeve, it is characterized in that forming and comprise the sleeve body and the decorative pearl on top of an official cap, the described sleeve body one end side of having mortise, the other end has the screwed hole corresponding with studs, side's mortise and screwed hole are all coaxial with sleeve body, the described decorative pearl on top of an official cap embeds sleeve body screwed hole bottom centre, and insert depth is greater than the radius of the decorative pearl on top of an official cap and less than the diameter of the decorative pearl on top of an official cap.
2, studs Fast Installation sleeve according to claim 1 is characterized in that an end of the corresponding screwed hole of sleeve body is conical.
