Description
Technical field
The utility model relates to a kind of wire clamp, the wire clamp used in the tension test of particularly a kind of aerial condutor or ground wire.
Background technology
Aerial condutor, before networking hanging wire, or after the use several years, according to relevant requirement, need carry out wire intensity and wire and to hold with a firm grip the testing experiment of force value.In process of the test, wire generally adopts hook-hang type to fix, and is generally the two ends crimping and tension-resisting clip at test lead, so that the hook of wire and fixedly carry out tension test.And strain clamp belongs to single use accessory, can not reuse, increase experimentation cost; In addition, the crimping of strain clamp easily causes wire that the phenomenon of position fracture occurs when tension test to crimp, and brings uncertain factor to test findings.
Summary of the invention
The utility model provides a kind of wire pull test clip, solves the technical matters that in wire pull test, strain clamp easily ruptures.
The utility model solves above technical matters by the following technical programs:
A kind of wire pull test clip, comprise cylindrical sleeve, central axis along cylindrical sleeve is provided with shaped central hole, central axis along cylindrical sleeve on the madial wall in the shaped central hole of cylindrical sleeve is provided with wedge shape strip hole at equal intervals radian, in wedge shape strip hole, activity is plugged with wedge shape fixture block, the square section of wedge shape fixture block is I-shaped, wedge shape fixture block is plugged in wedge shape strip hole by its wedge shape connection-peg activity, the clipper joint of wedge shape fixture block is arranged in shaped central hole, wire is provided with in shaped central hole, clipper joint and the wire clamp of three wedge shape fixture blocks are connected together.
The lateral wall of cylindrical sleeve is provided with and draws ear.
The utility model overcomes strain clamp and easily causes wire that the defect of position fracture occurs when tension test to crimp, and ensure that the reliable and stable, cost-saving of test figure and test findings, execute-in-place is simple and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of wedge shape fixture block 4 of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of wire pull test clip, comprise cylindrical sleeve 1, central axis along cylindrical sleeve 1 is provided with shaped central hole 2, central axis along cylindrical sleeve on the madial wall in the shaped central hole of cylindrical sleeve is provided with wedge shape strip hole 7 at equal intervals radian, in wedge shape strip hole 7, activity is plugged with wedge shape fixture block 4, the square section of wedge shape fixture block 4 is I-shaped, wedge shape fixture block 4 is plugged in wedge shape strip hole 7 by its wedge shape connection-peg 6 activity, the clipper joint 5 of wedge shape fixture block 4 is arranged in shaped central hole 2, wire 8 is provided with in shaped central hole 2, the clipper joint of three wedge shape fixture blocks is together with wire 8 clamping connection.
The lateral wall of cylindrical sleeve 1 is provided with and draws ear 3.
Described cylindrical sleeve 1 endoporus is round taper hole, longitudinally wedge shape strip hole 7 is had along round taper hole inwall, the wedge shape connection-peg 6 of grafting in wedge shape strip hole 7, when wire 8 draws god along shaped central hole 2 to small end, wedge shape fixture block 4 can move to little stomidium direction, and wire 8 presss from both sides tighter and tighter by the clipper joint of three wedge shape fixture blocks.After finishing test, negative drawing wire 8, wedge shape fixture block 4 can move to large stomidium direction, and wire 8 loosens by the clipper joint of three wedge shape fixture blocks.
Claims (2)
1. a wire pull test clip, comprise cylindrical sleeve (1), central axis along cylindrical sleeve (1) is provided with shaped central hole (2), it is characterized in that, the madial wall in the shaped central hole of cylindrical sleeve is provided with wedge shape strip hole (7) at equal intervals along the central axis of cylindrical sleeve radian, in wedge shape strip hole (7), activity is plugged with wedge shape fixture block (4), the square section of wedge shape fixture block (4) is I-shaped, wedge shape fixture block (4) is plugged in wedge shape strip hole (7) by its wedge shape connection-peg (6) activity, the clipper joint (5) of wedge shape fixture block (4) is arranged in shaped central hole (2), wire (8) is provided with in shaped central hole (2), the clipper joint of three wedge shape fixture blocks is together with wire (8) clamping connection.
