Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
A kind of fault detector, as shown in Figure 1, being slidably fitted with two along its width direction on bottom plate 11 including bottom plate 11
The opposite U-shaped frame 12 of a opening is fixedly installed with opposite clamping part by telescopic rod 3 on the opposite inner wall of two U-shaped framves 12
13, clamping part 13 is arranged along the length direction array of U-shaped frame 12, and spring 31, telescopic rod 3 and spring 31 are arranged with outside telescopic rod 3
One end is fixed on U-shaped frame 12, and the other end is fixed on clamping part 13, and when spring 31 is in normal condition, be open opposite two
The distance between a clamping part 13 is no more than the distance between two U-shaped openings of frame 12.According to the specification of electric wire tube body, make U-shaped
Frame 12 slides on bottom plate 11, adjusts the distance between two U-shaped framves 12, be adapted to it with the specification of cable, thus reduction at
This.Cable is located between two clamping parts 13, and spring 31 and telescopic rod 3 are compressed, but under the effect of the elastic force of spring 31 itself,
There are trend close to each other for two clamping parts 13, so that cable clamping be fixed.
As shown in Figure 1, offering dovetail groove 14 in the width direction on bottom plate 11, two U-shaped 12 low sides of frame are in dovetail shaped
(unmarked in figure), U-shaped frame 12 are respectively and fixedly installed in dovetail groove 14, are realized sliding of the U-shaped frame 12 on bottom plate 11, are avoided
U-shaped frame 12 is detached from bottom plate 11 in the vertical direction, guarantees the stability that U-shaped frame 12 slides.
As shown in Figure 1, after U-shaped 12 sandwiched cable of frame, dovetail groove 14 is blocked using snap-gauge 17, so that U-shaped frame 12 will not be from
It is slid in dovetail groove 14, blocks opening, U-shaped frame 12 is prevented to be detached from dovetail groove 14, improve safety in utilization；When unused, card
Plate 17 blocks dovetail groove 14, prevents U-shaped frame 12 from sliding out dovetail groove 14, improves practical function.
In order to realize clamping part stable holding cable, as shown in Fig. 2, 11 cental axial position of bottom plate setting rotation bolt 21, turns
The dynamic T-shaped structure of bolt 21, rotation 21 any two ends of bolt connect two U-shaped framves 12, by rotary motion bolt 21, rotate bolt 21 and pull two
U-shaped frame 12 is close to each other, then drives U-shaped 12 frame of frame close to each other, so that U-shaped frame 12 clamps cable；Meanwhile 11 center of bottom plate
Axle position is equipped with the fixing groove 16 of fixed rotation bolt 21, and after U-shaped 12 stable holding cable of frame, rotation bolt 21 is pressed down on to fixation
In slot 16, rotation bolt 21 be not subjected to displacement, so that fixed U-shaped 12 stable holding cable of frame.
As shown in Fig. 2, opposite clamping part 13 is in the opposite arcuate structure of being open, and if arc inner wall be equipped with dry elasticity
Protrusion 131, arcuate structure is capable of increasing the contact area between clamping part 13 and cable, and elastic bumps 131 are capable of increasing clamping
Frictional force between portion 13 and electric wire tube body improves clamping part 13 to the grip strength of cable, meanwhile, elastic bumps 131 can
Clamping part 13 is avoided to damage the outer wall of cable.
As shown in Fig. 2, cable is fastened between two clamping parts 13, spring 31 and telescopic rod 3 are compressed, but in spring
31 itself elastic force effect under, there are trend close to each other for two clamping parts 13, so that cable clamping be fixed.Wherein, U
Type frame 12 can protect cable, avoid it by the damage for the sharp portion slotted.The arcuate structure of clamping part 13 increases clamping part
Contact area between 13 and electric wire tube body, elastic bumps 131 can increase the frictional force between clamping part 13 and cable, improve folder
Portion 13 is held to the grip strength of cable, meanwhile, elastic bumps 131 can be avoided the outer wall that clamping part 13 damages electric wire tube body.
As shown in figure 3, rotation 21 low side of bolt is in square block, relatively fixed slot 16 is square slot, clamps cable in U-shaped frame 12
Afterwards, it rotates bolt 21 and fixing groove 16 buckles, so that U-shaped frame 12 is not sliding, meanwhile, there are protrusion 211 in any two sides of square block, convex
The setting of 211 elastic materials is played, relatively fixed 16 inner wall surrounding of slot uniform fluted 161, so that rotation bolt 21 is snapped into square groove
When 16, fixed effect is more preferably.
The course of work:
Before installation, according to the specification of cable, U-shaped frame 12 is slid onto the both ends of dovetail groove 14 so that two U-shaped framves 12 it
Between distance be greater than the cable size that need to clamp.
When installation, cable is fastened between two clamping parts 13, rotation rotation bolt 21 keeps U-shaped frame 12 close to each other, bullet
Spring 31 and telescopic rod 3 are compressed, under the elastic force effect of spring 31 itself, two clamping parts 13 there are trend close to each other,
It is fixed to stablize cable clamping.Wherein, U-shaped frame 12 can protect cable, it is avoided to be damaged.The arc of clamping part 13
Structure increases the contact area between clamping part 13 and cable, the friction that elastic bumps 131 can greatly between clamping part 13 and cable
Power improves clamping part 13 to the grip strength of cable, meanwhile, elastic bumps 131 can be avoided clamping part 13 and damage the outer of cable
Wall.After U-shaped frame 12 clamps cable, in pressing rotation bolt 21 to groove, realizes and stablizing for U-shaped frame 12 is fixed.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
