Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The first embodiment is as follows:

the embodiment of the application discloses be applicable to the flexible department of main part and prevent subsiding the telescopic joint. Referring to fig. 1, the telescopic joint includes two wire casings 1 and a connecting pipe 2 used for connecting two wire casings 1 and having deformability, and a cable can penetrate through the connecting pipe 2 from one wire casing 1 to another wire casing 1. The connection pipe 2 includes pipe bodies 21 at both ends of the connection pipe 2 and a bellows tube 22 connected between the two pipe bodies 21. The cross sections of the pipe body 21 and the wire casing 1 are rectangular, the wire casing 1 can be inserted into the pipe body 21, and the outer wall of the wire casing 1 can abut against the inner wall of the pipe body 21. Organ pipe 22 and body 21 integrated into one piece, and organ pipe 22 has the fold, because subside inequality when the movement joint department that connecting pipe 2 placed, lead to the movement joint both sides height different, organ pipe 22 part can take place deformation thereupon to make the laminating of wire casing 1 homoenergetic at connecting pipe both ends place in subaerial and can not take place unsettledly, make wire casing 1 difficult emergence damage.

Referring to fig. 2, be provided with a plurality of first bolts 4 along body 21 outer wall on the body 21, correspond set up threaded hole on the body 21, set up the thread groove on the wire casing 1 corresponds, first bolt 4 can wear to establish body 21 and threaded connection on the thread groove of wire casing 1, fixes 2 both ends of connecting pipe respectively with two wire casings 1 mutually.

Referring to fig. 1 and 2, the connection parts of the connection pipe 2 and the two wire slots 1 are provided with waterproof mechanisms 3, each waterproof mechanism 3 is an elastic telescopic sleeve 31, and the telescopic sleeves 31 can be tightened on the connection parts of the wire slots 1 and the connection pipe 2, so that in rainy days, external water flow is difficult to flow into the wire slots 1 along the connection gaps between the wire slots 1 and the connection pipe 2. Accomodate before the use on the outer wall of connecting pipe 2, when wire casing 1 is connected in connecting pipe 2, the flexible cover 31 of pulling for the one end of flexible cover 31 cup joints and tightens up on the outer wall of wire casing 1, and the other end cup joints and tightens up on the outer wall of body 21. The elastic sleeve can be an elastic rubber sleeve, and can also be a heat-shrinkable sleeve and the like.

The implementation principle of the telescopic joint is suitable for preventing the main body from sinking at the telescopic position is as follows: connecting pipes 2 are used at some deformation joints to connect wire grooves 1 at two ends of the deformation joints together, only two wire grooves 1 are needed to be respectively inserted into two ends of the connecting pipe 2, thread grooves on the wire grooves 1 are aligned with thread holes on the connecting pipe 2, a first screw-in bolt 4 is screwed in, and then telescopic sleeves 31 at two ends of the connecting pipe 2 are pulled to cover the outer wall of the wire groove 1 to complete installation.

The second embodiment:

referring to fig. 3 and 4, the second embodiment is different from the first embodiment in that the waterproof mechanism 3 is different. Waterproof mechanism 3 includes first intubate 32 and the second intubate 33 of fixed connection on the 2 outer walls of connecting pipe on the outer wall of fixed connection on wire casing 1 outer wall, and outside wire casing 1 was located through integrated into one piece cover to first intubate 32 to have the opening towards 2 directions of connecting pipe, outside body 21 was located through integrated into one piece cover to second intubate 33, and has the opening towards 1 directions of wire casing, forms cavity 7 between second intubate 33 inner wall and the 2 outer walls of connecting pipe. When the trunking 1 is inserted into the connection pipe 2, the outer wall of the connection pipe 2 abuts against the inner wall of the first insertion pipe 32, the first insertion pipe 32 is inserted into the cavity 7, and the outer wall of the first insertion pipe 32 abuts against the inner wall of the second insertion pipe 33, so that external water flow is difficult to enter the trunking 1.

Referring to fig. 4 and 5, in order to improve the tightness between the first insertion tube 32 and the inner wall of the cavity 7, an insertion plate 331 is fixedly connected to the inner bottom wall of the cavity 7 in the circumferential direction, an end of the insertion plate 331 facing the first insertion tube 32 is in a tip structure, an end of the first insertion tube 32 facing the cavity 7 is provided with a bayonet 321 into which the insertion plate 331 is inserted, and when the first insertion tube 32 is inserted into the cavity 7, the insertion plate 331 can be inserted into the bayonet 321. And the inner diameter of the bayonet 321 is smaller than the thickness of the insertion plate 331, when the insertion plate 331 is inserted into the bayonet 321, the inner wall of the bayonet 321 is extruded and deformed, and can further abut against the inner wall of the cavity 7. The outer wall of the inserting plate 331 is wrapped with a water stop film 5 to enhance the waterproof effect, and the water stop film 5 is a sealing strip.

Referring to fig. 4 and 5, a plurality of first bolts 4 are connected to the second insertion tube 33 along the outer wall of the second insertion tube 33 in a threaded manner, threaded holes are correspondingly formed in the second insertion tube 33, threaded grooves are correspondingly formed in the first insertion tube 32, and the second bolts 6 can be threaded through the second insertion tube 33 and are in threaded connection with the threaded grooves of the first insertion tube 32, so that the first insertion tube 32 and the second insertion tube 33 are fixed together. A gasket is arranged between the first bolt 4 and the outer wall of the second insertion tube 33, so that the abutting effect of the second bolt 4 is improved.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
