Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but execution mode of the present utility model is not limited to this.
Embodiment 1:
As depicted in figs. 1 and 2, cable orifice protecting device comprises sleeve 1 and running-on 2, and sleeve 1 is hollow cylindrical, and running-on 2 is hollow taper tubular, and the internal diameter of the little head end of running-on 2 and external diameter are all identical with sleeve 1, and its little head end is connected to sleeve 1 left end.
Described sleeve 1 is formed by rectangular slab two side direction bent intermediate, and described running-on 2 is formed to bent intermediate by trapezoidal plate two waists; Described rectangular slab does not contact to the both sides of bent intermediate, in sleeve 1 side, form a gap, two waists of described trapezoidal plate do not contact yet, in running-on 2 sides, form a gap, sleeve 1 side is connected with the gap of running-on 2 sides, form one and from running-on 2 left ends, extend to the slit gap 5 of sleeve 1 right-hand member along sleeve 1 and running-on 2 axis directions, making the cross section of sleeve 1 and running-on 2 not closed is an annulus, and sleeve 1 and running-on 2 sidewalls are not closed.In the present embodiment, the internal diameter of sleeve 1 and running-on 2 is greater than cable internal diameter, it is mainly used in when cable pulls in aperture cable to protect, its using method is, one end that running-on 2 radiuses are less and sleeve 1 stretch in the hole that cable is about to penetrate or penetrated, the larger one end of running-on 2 radiuses is outside hole, and cable passes in sleeve 1 and running-on 2, and while pulling cable like this, sleeve 1 and running-on 2 just can effectively avoid cable to be damaged by aperture; Sleeve 2 and running-on 2 adopt non-closing structure, and it can adjust its external diameter to adapt to the size in aperture according to the size in aperture, and when larger in aperture, its external diameter can arrange greatlyr, now slit gap 5 wider width; Hour, its external diameter can arrange littlely in aperture, and slit gap 5 is narrower, and when aperture is very little, the outer wall of its slit gap both sides Shang Xia 5 also can be overlapping, and slit gap 5 is just blocked, so it can be suitable for the aperture of multiple different pore size, and versatility is good; The size of sleeve 1 and running-on 2 can be limited by aperture, also can limit by the position-limit mechanism on running-on 2.
In order to prevent slit gap 5, block cable, the upper semi-circle part of described sleeve 1 and running-on 2 offers the first arc-shaped slot 21 that cross section is semi-annular shape (being that its arc length equals the general of girth) diametrically, lower half circle partly offers the second arc-shaped slot 22, described the first arc-shaped slot 21 and the second arc-shaped slot 22 are all communicated with slit gap 5, and the arc length of arc 4 is greater than the arc length of slit gap 5 correspondences and the arc length sum of the second arc-shaped slot 22 and is less than the first arc-shaped slot 21 and the arc length summation of the second arc-shaped slot 22; Like this, arc 4 just can slide on the arc track of the first arc-shaped slot 21 and the second arc-shaped slot and slit gap formation, and when adjusting the internal diameter of sleeve 1 and running-on 2 according to aperture size, arc 4 does not affect this adjustment.When not using, arc 4 is arranged in the first arc-shaped slot 21, because the arc length of the first arc-shaped slot 21 is longer, therefore arc 4 can not glide voluntarily, while having adjusted the internal diameter of sleeve 1 and running-on 2 when coming into operation, will rotate arc 4, its lower end is slipped in the second arc-shaped slot 22, because the arc length of arc 4 is greater than the arc length of slit gap 5 correspondences and the arc length sum of the second arc-shaped slot 22, so it must shelter from slit gap 5, prevents that cable from snapping in slit gap 5.
Preferably; described the second arc-shaped slot 22 is less than half of arc length of the first arc-shaped slot 21; running-on 2 and sleeve 1 are not arrived bottom in the second arc-shaped slot 22 lower ends; its cross section does not also form one 1/4 circle, to guarantee that arc 4 can block the internal diameter adjustment that slit gap 5 does not affect again sleeve 1 and running-on 2 well.
Due in general use due to Action of Gravity Field, cable generally stretches in running-on 2 from the bottom up, so running-on 2 left end downsides are also provided with arc flange 6, arc flange 6 and running-on 2 left end smooth connections, the resistance bringing to cable to reduce running-on 2.
The above-mentioned trapezoidal plate that is used to form running-on 2 is rubber slab with the rectangular slab that is used to form sleeve 1, also can adopt the more soft material of other quality to make, such as but not limited to plastics in practical application.
Embodiment 2:
On the basis of embodiment 1, cable orifice protecting device in the present embodiment also comprises the position-limit mechanism 3 being arranged on running-on 2, described position-limit mechanism 3 comprises that the first limiting plate 31, the second limiting plate 32, the first gag lever post 33, the second gag lever post 34,35: the first limiting plates 31 of fixed head are arranged on slit gap 5 tops, are fixed on running-on 2 outer walls; Fixed head 35 and the second limiting plate 32 are arranged on slit gap 5 belows, and fixed head 35 is fixed on running-on 2 outer walls, and the second limiting plate 32 is hinged on fixed head 35; On the second limiting plate 32, offer the through hole passing for the first gag lever post 33, described the first gag lever post 33 head ends are fixed on the first limiting plate 31, end is connected with the second gag lever post 34 through the through hole on the second limiting plate 32, vertical the first gag lever post 33 of described the second gag lever post 34.When the size of running-on 2 adopts position-limit mechanism 3 restriction, through hole on its second limiting plate 32 is tapped through hole, the first gag lever post 33 is threaded in this through hole, thereby regulates the first gag lever post 33 to be located in the external diameter that the width adjustment running-on 2 of slit gap 5 just can be adjusted in position in this through hole.
Embodiment 3
On the basis of embodiment 1 or embodiment 2, in the present embodiment, the second gag lever post 34 is hinged on the first gag lever post 33 ends by bearing pin 331, particularly:
As shown in Figure 3, the first gag lever post 33 ends are provided with groove 332, bearing pin 331 two ends are fixed on groove 332 both sides, described the second gag lever post 34 is set on bearing pin 332, the second gag lever post 34 can be turned to like this to length direction and when identical, can in the through hole of the second limiting plate 32, take off the first gag lever post 33 and the second gag lever post 34 with the first gag lever post 33.
Embodiment 4:
On the basis of above-described embodiment, running-on 2 in the present embodiment is bent downwardly, after its bending, axis is camber line, the radian that axis is corresponding is 30 °, and due to Action of Gravity Field, in general use, cable stretches in running-on 2 from below, in the present embodiment, running-on 2 is bent downwardly, and makes cable from below, stretch into running-on 2 dilatory convenient laborsaving when interior.
Below be only preferred implementation of the present utility model, protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, the some improvements and modifications not departing under the utility model principle prerequisite, should be considered as protection range of the present utility model.
