Connect sleeve

Technical field

The utility model relates to a kind of concrete component connection devices, and in particular to a kind of connection sleeve.

Background technique

Currently, prefabricated concrete pipe pile has been widely applied to building trade, generally needed using prefabricated concrete pipe pile More root canal piles are linked together, are in the prior art usually to be fixed with mechanical splice in concrete tubular pile end, machinery connects Head generally comprises plug, the connection structures such as sleeve and holding firmware.

Current connection sleeve is to process blind hole in sleeve body to form tube-in-tube structure closed at one end, in order to reduce The length of sleeve is connected, blind via bottom is generally machined to plane, therefore its processing technology is complicated, and processing cost is high.

Utility model content

The it is proposed of the utility model in view of the above problems, and a kind of connection sleeve of researching and designing comprising sleeve body and The structures such as tube end plate are covered, are machined with through-hole in sleeve body, can solve the complexity of the processing technology due to caused by processing blind hole The problem of.The technological means that the utility model uses is as follows:

A kind of connection sleeve, including sleeve body further include set tube end plate, are equipped with energy on the inside of one end of the sleeve body Set tube end plate is limited in the protrusion protruded to sleeve body centerline direction in sleeve, is set on the inside of the other end of the sleeve The chuck of oriented sleeve body centerline direction protrusion；

Further, the sleeve body is an integral structure with chuck；

Further, the chuck is the Snap ring structure being fixed on sleeve body inner wall；

Further, one end of the chuck towards set tube end plate is equipped with the card access surface of round tapered；

Further, the chuck is equipped with the guide surface of round tapered far from one end of set tube end plate；

Further, described to project through punching press and be made；

Further, the inner wall of the sleeve body is equipped with the limit that limitation set tube end plate is moved into sleeve body Portion, the limiting section carry out the bidirectionally limited of axial direction to set tube end plate with protrusion；

Further, the limiting section is step structure；

Further, circlip is equipped between the set tube end plate and protrusion or between set tube end plate and limiting section；

Further, one end of the sleeve body setting chuck is equipped with external screw thread.

Compared with the prior art, a kind of connection sleeve described in the utility model has the advantage that 1, connection sleeve packet Include sleeve body and set tube end plate, sleeve body and set tube end plate are separate structure, can to avoid due to direct processing blind hole and Bring processing technology is complicated；2, sleeve body and chuck are structure as a whole, and increase the intensity of sleeve；3, sleeve can use Tubing is processed, and is had and is saved raw material, and production cost is reduced.

In figure: 100, sleeve body, 101, set tube end plate, 102, protrusion, 103, chuck, 104, card access surface, 105, guiding Face, 106, limiting section, 107, circlip, 108, external screw thread.

Specific embodiment

As shown in Figures 1 to 4, connection sleeve disclosed by the utility model, including sleeve body 100 further include sleeve bottom Plate 101, be equipped on the inside of one end of the sleeve body 100 can by cover tube end plate 11 be limited in sleeve to sleeve body 100 The other end inside of the protrusion 102 of centerline direction protrusion, the sleeve is equipped with the card protruded to sleeve body centerline direction Platform 103.

As shown in Fig. 2, the sleeve body 100 is an integral structure with chuck 103, the chuck 103 is towards sleeve bottom One end of plate 101 is equipped with the card access surface 104 of round tapered, and the bus of card access surface and the angle of sleeve body center line be 30 °~ 80 °, preferably 40 °~50 °, the chuck 103 is equipped with the guide surface 105 of round tapered, guiding far from one end of set tube end plate 101 The bus in face and the angle of sleeve body center line are 30 °~60 °, preferably 45 °, and sleeve body is structure as a whole with chuck, can To enhance the intensity of connection sleeve, guide surface can be oriented to when carrying out and carrying out grafting with plug, fast and easy connection.

The inner wall of the sleeve body 100 is equipped with the limiting section that limitation set tube end plate 101 is moved into sleeve body 106, in the present embodiment, the limiting section is the step structure processed on sleeve body inner wall, the limiting section and protrusion The bidirectionally limited of axial direction is carried out to set tube end plate.Preferably, protrusion is by by being made the punching press of sleeve body end.It specifically adds Work process is as follows: first in the limiting section of sleeve body one end processing step structure, set tube end plate is placed at limiting section, it is then right The end of sleeve body carries out being stamped and formed out protrusion, so that set tube end plate is by bidirectionally limited between limiting section and protrusion.

Further, it is equipped between the set tube end plate 101 and protrusion 102 or between set tube end plate 101 and limiting section 106 Circlip 107, in the present embodiment, circlip 107 are set between set tube end plate 101 and protrusion 102, since protrusion is punching press At, therefore may have gap between limiting section, set tube end plate and protrusion, set tube end plate may alter in use It is dynamic, the service life for connecting sleeve is influenced, circlip is set, sleeve bottom plate and limiting section or protrusion can be made to be in close contact.

Further, one end that chuck 103 is arranged in the sleeve body 100 is equipped with external screw thread 108 in order to connect sleeve It is spirally connected with the end plate of concrete-pile.

Sleeve body and chuck, which can be an integral structure, is also possible to separate structure, as shown in figure 3, in the present embodiment In, the chuck 103 is the Snap ring structure being fixed on 101 inner wall of sleeve body, and chuck and sleeve body are threadably secured Connection.

Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
