Description
Technical field
This utility model relates to a kind of wire clamp, and it relates to a kind of wedge strain resistance cable clamp in particular.
Background technology
At present, in prior art, Authorization Notice No. is that the Chinese patent document of CN203039317U discloses a kind of wedge strain resistance cable clamp, the link plate being connected including the housing being provided with wedge cavities and the left clamping plate being arranged in described wedge cavities and right clamping plate with described housing；Described left clamping plate and right clamping plate insert from the front end of described wedge cavities, are provided with the breach arranged in the same direction with it on the top of described wedge cavities；Described left clamping plate and right clamping plate side close to each other are equipped with clamp groove, and two described clamp groove combinations constitute the clamp hole clamping external cable；This wedge strain resistance cable clamp is additionally provided with and makes left clamping plate and the right clamping plate under external force can the linkage structure of the most into/out described wedge cavities；Described linkage structure includes the draw-in groove being arranged on left clamping plate/right clamping plate top middle portion and is arranged on right clamping plate/left clamping plate top middle portion and can snap in the clamp of described draw-in groove；The top front of described left clamping plate and right clamping plate forms the boss raised up.
Above-mentioned wedge strain resistance cable clamp of the prior art, left clamping plate and right clamping plate are when pulling out wedge cavities, owing to left clamping plate increase with right clamping plate spacing, and left clamping plate and right clamping plate are all without its fixed structure, left clamping plate can independently disassemble with right clamping plate in wedge cavities, this the most directly affects is owing to left clamping plate and right clamping plate are the equal of individual components, uses and causes the loss of parts because easily neglecting in transportation, and impact is normal to be used.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of structural integrity high, does not easily cause the wedge strain resistance cable clamp that parts are lost.
For achieving the above object, this utility model provides following technical scheme: a kind of wedge strain resistance cable clamp, including being provided with the housing of wedge cavities, the pull bar being connected with housing and the left clamping plate being arranged in wedge cavities and right clamping plate, the side that described left clamping plate are relative with right clamping plate forms clamp groove；Described housing is positioned at the open top both sides of wedge cavities and is provided with draw runner, left clamping plate are provided with slide block with the end face of right clamping plate and are slidably connected to the draw runner of respective side, and described housing is positioned at the end that inserts of wedge cavities and is provided with the limited block conflicted with slide block formation when left clamping plate and right clamping plate are completely pulled out wedge cavities.
Effect of the present utility model is, wedge strain resistance cable clamp relative to prior art, this utility model arranges the structure of draw runner in the open top both sides of wedge cavities, the slide block making left clamping plate and right clamping plate is all slidably connected to the draw runner of respective side, by this slide construction, left clamping plate are restricted with the motion track of right clamping plate, move only along draw runner；Additionally the end that inserts in wedge cavities arranges the structure of limited block, is used for preventing left clamping plate and right clamping plate to be completely pulled out wedge cavities.Therefore so that left clamping plate and right clamping plate cannot be extracted out from direction of insertion, also cannot be close thus extract wedge cavities out to centre, and make mutual spacing increase just be enough to be used in wearing clamp cable by left clamping plate and right clamping plate part are extracted out wedge cavities.By using technique scheme so that all parts connects into an entirety mutually, prevent from causing parts to lose, to avoid unnecessary trouble in use, transportation.
This utility model is further arranged to: described slide block is provided with clip slot and is held on draw runner composition slide construction, described limited block is positioned at the side inserting end in draw runner opposite wedge chamber, described limited block be provided with for slide block unidirectional by thus the oblique surface that is connected with draw runner.
By using technique scheme, limited block arranges the structure of oblique surface, when installing left clamping plate and right clamping plate, it is easier to so that slide block passes through limited block, owing to slide block is only capable of unidirectional passing through limited block, just form mutual conflict structure at slide block with limited block by limited block rear slider, play the effect preventing left clamping plate and right clamping plate to be completely pulled out of wedge cavities.
This utility model is further arranged to: the front end of described slide block is provided with the inclined-plane coordinated when by limited block with oblique surface.
By using technique scheme, the inclined-plane coordinated with oblique surface it is provided with in installation process in the front end of slide block, it is easier to so that slide block passes through limited block, make to install more convenient laborsaving, simultaneously because slide block is to be conflicted with limited block by rear end, the position-limiting action of limited block is not impacted by the inclined-plane being arranged at front end.
This utility model is further arranged to: described left clamping plate are equipped with some location-plates with the bottom surface of right clamping plate position, and the location-plate of left clamping plate and right clamping plate is crisscross arranged；And described left clamping plate and right clamping plate are when being drawn out at utmost, the location-plate of left clamping plate and right clamping plate is provided with the coincidence part that the centrage with left clamping plate and right clamping plate overlaps all the time.
