Abstract
Provided is a pressure-bearing performance detection clamp for U-PVC tubular products. The pressure-bearing performance detection clamp for the U-PVC tubular products is composed of a first pin, an upper shell body, a nut, a second pin, an eccentric wheel, a threaded rod and a lower shell body, wherein one side of the upper shell body and one side of the lower shell body are connected through the first pin, the other side of the upper shell body and the other side of the lower shell body are connected through the threaded rod and the nut, a hole is formed in the top end of the threaded rod, the threaded rod and the eccentric wheel are connected through the hole and the second pin, and reverse teeth are arranged on the inner side of the upper shell body and the inner side of the lower shell body. The pressure-bearing performance detection clamp for the U-PVC tubular products is simple in structure and convenient to operate. When the pressure-bearing performance detection clamp for the U-PVC tubular products is used, the separation distance between the two stainless steel shell bodies can be adjusted through the nut, airtightness of the whole pressure-bearing performance detection clamp can be maximum through the eccentric wheel, and wear caused by frequent disassembly and assembly of the pressure-bearing performance detection clamp to screws and a wrench is avoided.
Description
Technical field
The utility model relates to the anchor clamps that pvc pipe material load performance detects, and relates in particular to a kind of U-PVC load performance and detects anchor clamps.
Background technology
Along with the fast development of China's water-saving irrigation cause, driven increasing rapidly of water-saving irrigation product consumption.The water-saving irrigation product has been detected as the prerequisite that becomes Support Construction high-quality water-saving irrigation project for this reason.The U-PVC pipe fitting is being brought into play vital effect as indispensable one large class in the saving product of water in Construction of Modern Agriculture, its product quality enjoys the concern of enterprise and businessman.Load performance is the important indicator of weighing the pipe fitting quality as one of conventional detection project of U-PVC pipe fitting.Traditional detection method is with anchor clamps that tubing is sealed at both ends and at the inner dress of tubing water, is the inner punching press of tubing with hydraulic press snap joint, reaches after the nominal pressure and does pressurize processing in a hour.Thereby anchor clamps become daily tubing and detect one of requisite a kind of instrument, ensure that detection can finish smoothly as detecting PVC anchor clamps that the tubing load performance detects conventional brace, especially some pipe with small pipe diameters making two screws that mainly rely on when the tubing load performance detects on the anchor clamps.But frequent demolition, installation are very large to the wearing and tearing of screw and spanner, during demolition, installation since the cause of screw so that work becomes loaded down with trivial details, efficient is low.Therefore the improvement of conventional brace seemed particularly necessary.
The utility model content
In sum, technical problem to be solved in the utility model provides a kind of U-PVC load performance and detects anchor clamps.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of U-PVC tubing load performance detects anchor clamps, is comprised of upper the first pin, upper shell, nut, the second pin, eccentric wheel, screw rod and lower house, and upper shell is connected by the first pin with a side of lower house, and opposite side is connected with nut by screw rod; The top perforate of screw rod, and with the second pin screw rod is linked to each other by this hole with eccentric wheel.
Above-mentioned upper shell and above-mentioned lower house inboard have sets one's teeth on edge.
The utility model compared with prior art has the following advantages:
1, owing to using hidden discount with pin one end to be linked to each other two housings in the utility model, therefore can reduce the use of screw, reduce wearing and tearing.
2, the top of screw rod is provided with the hole in the utility model, and eccentric wheel is linked to each other with screw rod, and nut can be regulated the distance between upper and lower casing easily, and eccentric wheel makes the sealing of anchor clamps reach maximum; Eccentric use makes the anchor clamps demolition, installation simple to operation.
3, the utility model is simple in structure, easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is Fig. 1 upper shell schematic internal view.
Fig. 4 is Fig. 1 lower house schematic internal view.
Among the figure: the 1-the first pin 1 2-upper shell the 4-the second pin 3-nut 5-eccentric wheel 6-screw rod 7-8-lower house of setting one's teeth on edge
The specific embodiment
Below in conjunction with description of drawings the utility model is described further:
Shown in Fig. 1,2,3,4, a kind of U-PVC tubing load performance detects anchor clamps, by upper the first pin 1, upper shell 2, nut 3, the second pin 4, eccentric wheel 5, screw rod 6, set one's teeth on edge 7 and lower house 8 form, it is characterized in that: upper shell 2 is connected by the first pin (1) with a side of lower house 8, and opposite side is connected connection by screw rod 6 with nut; The top perforate of screw rod 6, and with the second pin 4 screw rod 6 is linked to each other by this hole with eccentric wheel 5; Upper shell 2 and lower house 8 inboards have sets one's teeth on edge 7.
Embodiment
Before the tubulature material, at first by nut 3 spacing between upper shell 2 and the lower house 8 is tuned up, the tubing of milled chamfering is packed into; Secondly adjusting nut 3 is pressed movable eccentric wheel 5 again so that the spacing between upper shell 2 and the lower house 8 is turned down, makes the sealing of tubing in anchor clamps reach best.
Wherein: upper shell 2 and above-mentioned lower house 8 inboards have sets one's teeth on edge 7, and effect is tubing to be fixed on prevent slippage when the pressure-bearing in the anchor clamps.
Claims (2)
1. a U-PVC tubing load performance detects anchor clamps, formed by upper the first pin (1), upper shell (2), nut (3), the second pin (4), eccentric wheel (5), screw rod (6) and lower house (8), it is characterized in that: upper shell (2) is connected by the first pin (1) with a side of lower house (8), and opposite side is connected 3 by screw rod (6) with nut) connect; The top perforate of screw rod (6), and with the second pin (4) screw rod (6) is linked to each other by this hole with eccentric wheel (5).
