Abstract
An Inflating pin for a compressor comprises an elongated pin body (4) and is characterized in that a solid pin tip (1) is arranged at one end of the elongated pin body (4), and the other end of the elongated pin body (4) is connected with an air source connector (3). An air inlet hole (5) is arranged in the center of the elongated pin body (4), one end of the air inlet hole (5) is communicated with the air source connector (3), and at least one inflating hole (2) communicated with the air inlet hole (5) is arranged on the elongated pin body (4) at a position close to the solid pin tip (1). A ventilated opening portion is positioned on the lateral side of the pin, the diameter of the pin is gradually increased from the pin tip to the pin at the opening portion, transition is smooth, rubber scraps generated when rubber is pierced by the pin is prevented, and air can flow through the opening on the lateral side in the inflating process. The Inflating pin for the compressor is simple in structure, convenient in manufacturing and easy in insertion, rubber cannot be pierced off, and a pin hole cannot be blocked.
Description
Technical field
The utility model relates to a kind of compressor and makes instrument, especially a kind ofly charges into the Aerating needle of shielding gas, specifically a kind of compressor Aerating needle that can not stop up for compressor.
Background technique
At present; it is that compressor charges into shielding gas that compressor manufacturing enterprise generally adopts syringe needle; what the syringe needle of this entry needle partly adopted is the inclined hole structure; therefore in the time of the punctures caulking gum, be easy to result in blockage because of rubber enters in the injection orifice; and when gas injection pressure during greater than the rubber resistance of injection port; be easy to again scrap gum is brought in the compressor, cause medium pollution.This is not still had good Aerating needle at present can use for enterprise.
Summary of the invention
The purpose of this utility model is to adopt clinical syringe needles easily to result in blockage during at the inflation of existing compressor and the problem of medium pollution, design a kind of simple in structure, the compressor Aerating needle that can not stop up.
The technical solution of the utility model is:
A kind of compressor Aerating needle, comprise elongated needle body 4, it is characterized in that described elongated needle body 4 one ends are provided with solid needle point 1, the other end of elongated needle body 4 is connected with gas source connector 3, the center of described elongated needle body 4 is provided with an inlet hole 5, one end of inlet hole 5 is connected with gas source connector 3, is provided with an air-filled pore 2 that connects with inlet hole 5 at elongated needle body 4 at least near solid needle point 1 position.
The position of described air-filled pore 2 is positioned at inlet hole 5 near on the bottom of the solid needle heart 1.
The quantity of described air-filled pore 2 be one, two or more.
The shaft axis quadrature or the oblique of the shaft axis of described air-filled pore 2 and inlet hole 5.
Described practical needle point 1 tapered structure, and be connected smoothly with elongated needle body 4.
The beneficial effects of the utility model:
The utility model is by being put into the open part of ventilation the side of pin, and needle point becomes greatly gradually to the diameter of opening portion minute hand, seamlessly transits, and produces scrap gum when preventing needle-penetration rubber, and in gas replenishment process, gas flows out by the opening of side.It has simple in structure, and is easily manufactured, inserts easily, can not sting rubber, can not stop up pin hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of compressor Aerating needle, comprise elongated needle body 4, described elongated needle body 4 one ends are provided with solid needle point 1, practical needle point 1 is the sharp cone distal structure and is connected smoothly with an end of elongated needle body 4, the other end of elongated needle body 4 is connected with gas source connector 3, the center of described elongated needle body 4 is provided with an inlet hole 5, and an end of inlet hole 5 is connected with gas source connector 3, is provided with an air-filled pore 2 that connects with inlet hole 5 at elongated needle body 4 at least near solid needle point 1 position.The position of described air-filled pore 2 preferably is positioned at inlet hole 5 near on the bottom of the solid needle heart 1, the lower end of inlet hole 5 preferably can be deep into the part of solid needle point 1, but must guarantee the wall thickness of solid needle point 1 in case oppressed deformation fracture by rubber in the using process.During concrete enforcement, the quantity of air-filled pore 2 can be one, two or more.The shaft axis of the shaft axis of described air-filled pore 2 and inlet hole 5 can be a quadrature, also can be the oblique state.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
