Put the gradient in described horizontal socket and vertical socket junction internal and the bottom of two horizontal sockets between.
And, the top of described screw rod is extended on the upper end of described nut, and the bottom of described screw rod is in the type of falling t shape,
It is arranged between horizontal socket and the gradient inner surface of vertical socket junction.
And, the inner side of described clamping anchor ear is all fixed with described expansion link outer end.
Advantage of the present utility model and having the beneficial effect that
1st, innovative point of the present utility model is the cooperation shifting in vertical socket for the lead-screw using screw rod and nut
Dynamic, drive plastic shrapnel to deform upon, apply pressure to spring, so that inner sleeve socket is ejected from horizontal socket, by expansion link band
Dynamic clamp jaw, adjusts the length of screw rod behind the two ends of clamp jaw connection cable again, so that screw rod is screwed out from vertical socket, spring
All recovering deformation with elastoplast, thus driving in the horizontal socket of inner sleeve socket retraction, and then completing the peace of two ends crosslinked cable
Dress, designs ingenious, compact, saves the space of building of dust-proof shed, save space, cost-effective, easy to use, economic ring
Protect.
2nd, joint, according to the principle of frame for movement and the actual connection procedure of crosslinked cable, is cleverly designed by this utility model
Become the type of falling t structure, be in addition all set with clamping anchor ear in the outside of clamp jaw, by clamping the sealing cooperation of anchor ear and clamp jaw
Realize the dust reduction capability of cable connector, need not artificially clear up, good airproof performance, easy to use, good dustproof effect.
3rd, in this utility model, horizontal socket is provided with the gradient with the junction of vertical socket, and the bottom of screw rod is in t
Type shape, is fittingly disposed between horizontal socket and the gradient inner surface of vertical socket junction, increases screwing when screw rod declines
Pressure to plastic shrapnel, and gradient be arranged on plastic shrapnel recover elastic deformation when there is certain recovery space so that
Mechanical force has certain space buffer, device will not be caused to damage, improve service efficiency.
4th, this utility model structure is simple, it is ingenious reasonable to design, and cleverly utilizes plastics bullet by the setting of screw flight
The pressure of piece and spring completes the joint installation of cable with recovering elastic force produced by elastic deformation, makes the installation of crosslinked cable fast
Fast, convenient and efficient.Solve need in prior art build dust-proof shed and arrangement plastic seal cloth waste time and energy and cost relatively
Height causes the problem of the wasting of resources it is ensured that the safety of voltage levels cable construction environment is it is adaptable to widely popularize application.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the use state figure of Fig. 1.
Specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, no
It is determinate it is impossible to protection domain of the present utility model is limited with this.
As shown in figure 1, a kind of crosslinked cable erection joint with dust reduction capability, including the type of falling t erection joint body, spiral shell
Bar 1, inner sleeve socket 6, expansion link 7, clamp jaw 8 and clamping anchor ear 9.The described type of falling t erection joint body is cavity structure, by
One vertical socket 3 and two horizontal sockets 10 form, and two described horizontal socket specular are arranged on described vertical tube
The lower end of cylinder, is provided with the gradient in described horizontal socket with the junction of vertical socket.
