As depicted in figs. 1 and 2, cable locking device comprises body 3, upper clamp 1 and lower clamp 2.Upper clamp 1 is used for engaging with body 3.Lower clamp 2 is positioned on the body 3, can with body 3 integrally formed or independent formation.Upper clamp 1 cooperatively interacts with lower clamp 2, is used for locking together cable 4 (referring to Fig. 5, Fig. 6 and Fig. 7).

Particularly, as shown in Figure 1, on two madial walls of upper clamp 1, be respectively arranged with a grab 101 (grab 101 on the madial wall only is shown among the figure).On two lateral walls of body 3, be respectively arranged with four draw-in grooves 301,302,303,304.This four draw-in grooves 301,302,303,304 are spaced along short transverse, thereby make each draw-in groove 301,302,303,304 be in the different height position.When upper clamp 1 moved down, grab 101 can be respectively engages with the draw-in groove 301,302,303,304 of differing heights position, so that the cable 4a of locking different size, 4b, 4c (referring to Fig. 5, Fig. 6 and Fig. 7).

Need to prove that although in illustrated example, be provided with four draw-in grooves 301,302,303,304, the quantity of draw-in groove can also be two, three, five or more a plurality of.

Fig. 3 is the partial enlarged drawing of the cable locking device of Fig. 2, shows the concrete structure of a grab and a draw-in groove.

Particularly, as shown in Figure 3, grab 101 comprises horizontal sides 101a, inclined lead limit 101c and is connected horizontal sides 101a and the vertical edge (101b) of inclined lead limit 101c.

Accordingly, each draw-in groove 301,302,303,304 comprises horizontal sides 301a, inclined lead limit 301c and vertical edge 301b.

Under grab and state that draw-in groove engages, the horizontal sides 101a of grab 101, inclined lead limit 101c and vertical edge (101b) are fastened togather with horizontal sides 301a, inclined lead limit 301c and the vertical edge 301b of draw-in groove respectively.

Need to prove that the structure of grab and draw-in groove is not limited to illustrated example, also should comprise being applicable to any grab of the present invention and draw-in groove in the prior art.For example, the horizontal sides of grab is designed to a little towards tilting, and the horizontal sides of draw-in groove is designed to a little towards having a down dip, like this, the self-locking effect is better.

Preferably, as shown in Figure 1, on two sidewalls of upper clamp 1, offer the guiding groove 102 of vertical extension respectively.Simultaneously, on two sidewalls of body 3, be respectively arranged with the guiding rib 305 of vertical extension.The guiding rib 305 of upper clamp 1 is inserted in the guiding groove 102 of body 3, is used to guide upper clamp 1 to move vertically with respect to body 3.

Preferably, as shown in figures 1 and 3, the top of the sidewall of body 3 is provided with transition leading edge 306, and this transition leading edge 306 cooperates with the inclined lead limit 101c of grab 101, is used to guide upper clamp 1 to carry out the transition to body 3 smoothly.

Preferably, as shown in Figure 1, for the arc-shaped outer surface with cable 4 closely cooperates, upper clamp 1 has arc inner peripheral surface 103, and lower clamp 2 also has arc inner peripheral surface 201.

More preferably, the arc inner peripheral surface 201 of the arc inner peripheral surface 103 of upper clamp 1 and lower clamp 2 has identical radius of curvature.

More preferably, the arc inner peripheral surface 201 of lower clamp 2 is provided with many axially extended elongated channels 202, is used to increase coefficient of friction, thereby increases the confining force of locking cable 4.Need to prove; Arc inner peripheral surface 103 that also can upper clamp 1 is provided with many axially extended elongated channels, perhaps also can on the arc inner peripheral surface 201 of the arc inner peripheral surface 103 of upper clamp 1 and lower clamp 2, be provided with many axially extended elongated channels simultaneously.Certainly, the instance that increases coefficient of friction is not limited to elongated channels, can also on the arc inner peripheral surface of upper clamp 1 and/or lower clamp 2, be respectively arranged with a plurality of tiny convexities, increases coefficient of friction.

Preferably, as shown in Figure 1, under the situation that intensity allows, grab 101 is arranged near the lower edge of madial wall of upper clamp 1 as far as possible, can obtain preferable and bigger elastic deformation force like this.

Fig. 4, Fig. 5, Fig. 6 and Fig. 7 show the operation principle of cable locking device of the present invention.

Fig. 4 shows the preparatory installment state of locking cable; When the grab 101 of upper clamp 1 engages with first draw-in groove 301 of lower clamp 2; Upper clamp 1 is not locked cable 4 with lower clamp 2, but ready for next step locking operation, this moment, first draw-in groove 301 was configured to install in advance draw-in groove.Need to prove, also preparatory installation draw-in groove can be set, that is, when the grab 101 of upper clamp 1 engages with first draw-in groove 301 of lower clamp 2, upper clamp 1 and lower clamp 2 locking cables 4.

Fig. 5 shows that locking has the cable of first diameter, and when the grab 101 of upper clamp 1 engaged with second draw-in groove 302 of lower clamp 2, upper clamp 1 and lower clamp 2 were locked the cable 4a of first diameter together.

Fig. 6 shows that locking has the cable of second diameter, and when the grab 101 of upper clamp 1 engaged with the 3rd draw-in groove 303 of lower clamp 2, upper clamp 1 and lower clamp 2 were locked the cable 4b of second diameter together.

Fig. 7 shows that locking has the cable of the 3rd diameter, and when the grab 101 of upper clamp 1 engaged with the 4th draw-in groove 304 of lower clamp 2, upper clamp 1 and lower clamp 2 were locked the cable 4c of the 3rd diameter together.
