Description

Novel bar planting pull-out test fixture

Technical Field

The utility model belongs to the technical field of drawing clamps, and particularly relates to a novel bar planting drawing test clamp.

Background

At present, when the tensile bearing capacity is pulled in the drawing antistatic load test, the sampling detection is usually carried out at different places, and the clamps with different model sizes are carried when the model sizes of detection targets are not clear, so that the carrying is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel bar planting drawing test fixture, which solves the problem that in the prior art, fixtures of different types and sizes need to be carried and are inconvenient to carry.

In order to achieve the purpose, the utility model provides the following technical scheme: including pressing from both sides the pipe, two shoulder holes have all been seted up to both ends inner wall about pressing from both sides the pipe, four equal threaded connection has the screw thread push rod, four in the shoulder hole the screw thread push rod top all is provided with the locking handle, the lower part inner wall both sides of shoulder hole are rotated and are connected with the dwang, two the bottom of dwang is rotated and is connected with splint, the up end both sides of splint all are provided with the spring, the inner wall both sides at the shoulder hole are connected respectively to the other end of spring, the up end at splint is supported to the bottom of screw thread push rod, be equipped with the arc wall on the splint, be provided with the slipmat on the inner wall of arc wall.

Preferably, a connecting ring is arranged on one side of the clamping pipe.

Preferably, the inner wall of the lower part of the stepped hole is provided with a sliding groove, a sliding block is arranged in the sliding groove, and the sliding block is arranged at one end of the rotating rod.

Compared with the prior art, the utility model has the beneficial effects that: when carrying out anchor clamps experiment, put into the double-layered pipe with the one end of reinforcing bar, rotate the screw thread internal rotation that locking handle drove the screw thread push rod and rotate downwards in the screw thread upper end of shoulder hole, make the lower extreme of screw thread push rod support the upper end of splint, screw thread push rod promotes splint when rotating downwards, make the slider slide in the spout, the spring stretches, and then realize that splint press from both sides tightly to the reinforcing bar, arc wall and slipmat prevent in the experiment reinforcing bar to break away from because of the anchor clamps atress is too big, connect the go-between after pressing from both sides tightly to test the appearance, it upwards rotates to rotate the screw thread push rod after the experiment is ended, make the screw thread push rod break away from splint, make the spring contract, the slider upwards slides in the slider and resets splint.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a cross-sectional view of FIG. 1;

fig. 3 is an enlarged schematic view of a portion a of fig. 2.

In the figure: 1. clamping the pipe; 2. a stepped hole; 3. a threaded push rod; 4. locking the handle; 5. rotating the rod; 6. A splint; 7. a spring; 8. an arc-shaped slot; 9. a non-slip mat; 10. a connecting ring; 11. a chute; 12. a slide block.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, 2 and 3, an embodiment of the utility model provides a pipe clamp comprising a pipe clamp 1, wherein two stepped holes 2 are respectively formed in the inner walls of the upper end and the lower end of the pipe clamp 1, inner threads are formed in the upper portions of the inner walls of the stepped holes 2, threaded push rods 3 are respectively connected to the four stepped holes 2 in a threaded manner, locking handles 4 are respectively welded to the top ends of the four threaded push rods 3, rotating rods 5 are rotatably connected to the left and right sides of the inner wall of the lower portion of the stepped holes 2, clamping plates 6 are rotatably connected to the bottom ends of the two rotating rods 5, springs 7 are respectively welded to the two sides of the upper end face of each clamping plate 6, the bottom ends of the threaded push rods 3 are abutted against the upper end face of each clamping plate 6, an arc-shaped groove 8 is formed in each clamping plate 6, anti-skid pads 9 are welded to the inner wall of each arc-shaped groove 8, a connecting ring 10 is welded to the right side of the pipe clamp, sliding grooves 11 are respectively formed in the left and right sides of the inner wall of the lower portion of each stepped hole 2, a slide block 12 is connected in the slide groove 11 in a sliding way, and the slide block 12 is welded at the right end of the rotating rod 5.

The working principle of the embodiment is as follows: when carrying out anchor clamps experiment, put into double-layered pipe 1 with the one end of reinforcing bar, it rotates downwards to rotate locking handle 4 and drive screw push rod 3 at the screw thread internal rotation of 2 upper ends of shoulder hole, the lower extreme that makes screw push rod 3 supports the upper end of splint 6, screw push rod 3 promotes splint 6 when rotating downwards, make slider 12 slide in spout 11, spring 7 stretches, and then realize splint 6 and press from both sides tightly the reinforcing bar, arc wall 8 and slipmat 9 prevent that the reinforcing bar breaks away from because of the anchor clamps atress is too big in the experiment, test the tight back of clamp is experimental with go-between 12 connection tester, it upwards rotates screw push rod 3 after the experiment finishes, make screw push rod 3 break away from splint 6, make spring 7 shrink, slider 12 upwards slides in slider 11 and resets splint 6.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
