Description
Technical field
The utility model relates to a kind of clamping device, especially a kind of clamping device of PVC pipeline.
Background technology
Existing PVC pipeline clamping device is many, mostly just clamps the corresponding both sides of pipeline, causes discontinuity, due to PVC limited strength, so easily make pipeline deform; Some are also had to be the special fixtures arranged according to existing PVC pipeline shape or size correspondence, pervasive poor-performing.
Summary of the invention
The technical problems to be solved in the utility model is the problem that existing clamping device force is uneven, universality is poor.
In order to solve the problems of the technologies described above, PVC pipeline fixture of the present utility model, comprise the wheel flange of ring-type, be looped around wheel flange peripheral and be provided with the elastic shrinkage circle of closing in, the handle be fixedly connected with through elastic shrinkage circle and with wheel flange outer ring surface, four depression bars, shrink screw rod, the circumferentially equidistant of wheel flange is provided with the pilot hole that four are pointed to the center of circle, elastic shrinkage circle is provided with the shrinkage hole of bar shaped in the corresponding position of pilot hole, the closing in place both sides of elastic shrinkage circle are respectively equipped with left plate and right plate, left plate is provided with screwed hole, shrink screw rod to screw with the screwed hole on left plate through after right plate, one end of depression bar is provided with bayonet socket, the other end points to the center of circle through pilot hole, bayonet socket is embedded in shrinkage hole and also can slidably reciprocates along shrinkage hole.
Adopt four depression bars to exert a force to pipeline from four direction up and down, not only ensure that the stability that pipeline clamps, and under the same effect of elastic shrinkage circle, make the force size of four direction identical, ensure that uniform force; Adopt four depression bars to exert a force to pipeline from four direction up and down, the shape of pipeline can be considered, even if pipeline is square or triangle can clamp too; Adopting bayonet socket can realize shrinking screw rod bayonet socket and shrinkage hole relative sliding when shrinking with coordinating of shrinkage hole, preventing again depression bar from dropping in pilot hole.
As further improvement of the utility model scheme, the end face that depression bar points to one end, the center of circle is provided with antislip cog.Antislip cog is adopted can effectively to prevent from, in pipeline clamping process, pipe slides occurs.
As further restriction scheme of the present utility model, depression bar and pilot hole are matched in clearance.Depression bar is flexible in pilot hole to adopt matched in clearance to ensure, can prevent again depression bar from rocking in pilot hole, affect gripping performance.
The beneficial effects of the utility model are: (1) adopts four depression bars to exert a force from four direction up and down to pipeline, not only ensure that the stability that pipeline clamps, and under the same effect of elastic shrinkage circle, make the force size of four direction identical, ensure that uniform force; (2) adopt four depression bars to exert a force to pipeline from four direction up and down, the shape of pipeline can be considered, even if pipeline is square or triangle can clamp too; (3) adopting bayonet socket can realize shrinking screw rod bayonet socket and shrinkage hole relative sliding when shrinking with coordinating of shrinkage hole, preventing again depression bar from dropping in pilot hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model.
Detailed description of the invention
As illustrated in fig. 1 and 2, PVC pipeline fixture of the present utility model comprises: the wheel flange 1 of ring-type, be looped around wheel flange 1 peripheral and be provided with the elastic shrinkage circle 2 of closing in, the handle 3 be fixedly connected with through elastic shrinkage circle 2 and with wheel flange 1 outer ring surface, four depression bars 4, shrink screw rod 5, the pilot hole 6 that four are pointed to the center of circle is provided with the circumferentially equidistant of wheel flange 1, elastic shrinkage circle 2 is provided with the shrinkage hole 8 of bar shaped in the corresponding position of pilot hole 6, left plate 9 and right plate 10 is respectively equipped with in the closing in place both sides of elastic shrinkage circle 2, left plate 9 is provided with screwed hole, shrink screw rod 5 to screw through the screwed hole after right plate 10 and on left plate 9, bayonet socket 7 is provided with in one end of depression bar 4, the other end points to the center of circle through pilot hole 6, bayonet socket 7 is embedded in shrinkage hole 8 and also can slidably reciprocates along shrinkage hole 8, wherein, depression bar 4 and pilot hole 6 are matched in clearance.
As shown in Figure 1, in order to improve the gripping performance of fixture further, the end face pointing to one end, the center of circle at depression bar 4 is provided with antislip cog 11.
Fixture of the present utility model in use, first screw rod 5 is shunk according to the size adjustment of pipeline, fixture is enclosed within pipeline smoothly, then screw rod 5 is shunk in adjustment, elastic shrinkage circle 2 is made to impose onesize pressure to four depression bars 4, now four depression bars 4 just clamp from four direction up and down pipeline, then just associative operation can be carried out by handle 3 pairs of pipelines, after operation completes, contraction screw rod 5 is reversely rotated and unclamp, elastic shrinkage circle 2 is due to elasticity recovery original form, and four depression bars 4 are extracted out from pilot hole 6, again fixture is removed from pipeline.
