Abstract
The utility model provides a stay tube clamp which pertains to the mechanical technique field, especially relates to a stay tube device used for connecting plastic tubes. The utility model solves the problems of complex structure and trouble operation of the existing stay tube. The stay tube clamp includes a hand grip one and a hand grip two, the hand grip one and the hand grip two are articulated with each other at their ends. The stay tube clamp is characterized in that a spring is provided between the hand grip one and the hand grip two, a stay tube plug one and a stay tube plug two with a semi-cylindrical shape are separately provided along the hand grip one and the hand grip two at the ends of the hand grip one and the hand grip two, the stay tube plug one and the stay tube plug two have same size and corresponding position, and form an integrated cylinder when joined with each other. The utility model has very simple structure, plastic tubes with different size can be expanded by the same stay tube clamp, and the operation is very convenient.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of stay tube device that is used for the plastic tube connection.
Background technology
At present, in the oil of tap water pipe line or industrial use, air pipe, plastic tube is widely used.When plastic tube was connected with pipe joint or valve, a kind of comparatively ideal connected mode was that the plastic tube tight fit is socketed in the adapter that is connected, and connected end with collar or cutting ferrule then and waled.Under normal conditions,, need to support greatly, it is put smoothly with the link of a machine tool with plastic tube because the internal diameter of plastic tube is slightly less than the external diameter of the adapter that is connected.
Though it is big to adopt the instrument of common nipper plier and so on the mouth of pipe of plastic tube can be supportted, troublesome poeration, and can not make mouth of pipe support big equably, even can damage the mouth of pipe.For this reason, Chinese patent 97224266X provides a kind of " Pipe expanding tongs ", and it comprises mutually hinged pincers handle I and pincers handle II, and pincers handle II is provided with the cone seat that is fixed with one, head is that cone shape cone is hinged on the pincers handle I, and 4-10 the pawl of locating with spring coil is enclosed in outside the cone.This Pipe expanding tongs is the cone reach that utilizes pincers pommel portion, pawl is opened and the mouth of pipe is dilated.Though use this Pipe expanding tongs can make the mouth of pipe expansion of plastic tube, its complex structure, particularly when the internal diameter varies of plastic tube, pawl of its pincers pommel portion needs to change, and operation very bothers.
Summary of the invention
The purpose of this utility model is in order to address the above problem, a kind of Pipe expanding clamp of new structure to be provided, making it have characteristics such as simple in structure, easy to operate, that expander is even.
The purpose of this utility model can realize by following technical proposal: this Pipe expanding clamp comprises handle one and handle two, handle one is hinged in their end with handle two, it is characterized in that being provided with between handle one and the handle two spring, end at handle one and handle two is respectively equipped with stay tube plug one and the stay tube plug two that is the semicylinder shape along the direction perpendicular to handle one and handle two, and stay tube plug one and stay tube plug are two measure-alike, the position is corresponding, and lumping together becomes a complete cylinder.
In this Pipe expanding clamp, be not subjected to external force to do the time spent, handle one and handle two can be in open configuration under the effect of spring.At this moment, stay tube plug one is closed together with stay tube plug two.
This Pipe expanding clamp at first inserts stay tube plug one and stay tube plug two end that needs the plastic tube that be connected in use, and the external diameter when stay tube plug one and stay tube plug two are in closure generally speaking can just insert it slightly less than the internal diameter of plastic tube; Firmly make handle one and handle two closures then, stay tube plug one that lump together this moment and stay tube plug two open under the effect of handle one and handle two, have also just supportted the internal diameter of plastic tube end big; At last, release handle one and handle two, they reset under the effect of spring, and stay tube plug one lumps together again with stay tube plug two, can take out from the end of plastic tube.
Because the plastic behavior of plastic tube after its end is strutted, can't be restored at once.At this moment, the end of plastic tube can be inserted in the adapter of the pipe joint that will connect or valve, and put that collar is fastening to link together them.
Same Pipe expanding clamp is used for the plastic tube of different inner diameters in order to make, in above-mentioned Pipe expanding clamp, its stay tube plug one and stay tube plug two are step-like, and both diminish by the formed cylindrical external diameter in closed back from the inside to the outside successively.During use, just can plastic tube be inserted on the step surface of the stay tube plug that is complementary with it according to the different inner diameters of plastic tube.
Obviously, structure of the present utility model is very simple.Because the stay tube plug adopts step-like structure, can use and same Pipe expanding clamp be expanded the plastic tube of different size, and need not change the stay tube plug, so easy to operate.In this Pipe expanding clamp, because the end of stay tube plug is cylindric, the opened part that makes plastic tube is vertically or laterally all evenly to obtain expansion, will help improving the fastness and the sealing of plastic tube junction.

Fig. 1 is the profile schematic diagram of the Pipe expanding clamp that provides of the utility model.
Fig. 2 is the side view of the Pipe expanding clamp that provides of the utility model.
Fig. 3 is the rearview of the Pipe expanding clamp that provides of the utility model.
Among the figure, 11, handle one; 12, handle two; 21, the stay tube plug one; 22, the stay tube plug two; 23, step; 3, spring; 4, bearing pin.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, handle 1 and handle 2 12 in its end by bearing pin 4 and hinged.In the present embodiment, near bearing pin 4 places spring 3 is set at handle 1 and handle 2 12.By spring 3, make handle 1 and handle 2 12 be in open configuration on the one hand; On the other hand, make stay tube plug 1 and stay tube plug 2 22 closures become a complete cylinder.
Stay tube plug 1 and stay tube plug 2 22 are semi-cylindrical, and it is measure-alike and the position is corresponding.In the present embodiment, the both sides of handle 1 and handle 2 12 are equipped with stay tube plug 1 and stay tube plug 2 22.Obviously, the size difference of both sides stay tube plug is applicable on the plastic tube of more specifications this Pipe expanding clamp.In the present embodiment, a side stay pipe plug has two steps 23, and the plastic tube expansion that can be suitable for three kind of different inner diameters is used; Opposite side stay tube plug does not have step 23, and the plastic tube expansion that is suitable for a kind of internal diameter is used.
Usually, this Pipe expanding clamp employing metal is that material is made.This Pipe expanding clamp can be widely used on various types of plastic tubes or the multiple tube.
