Description

Fixing buckle

Technical Field

The utility model relates to a pneumatic control field especially relates to a fixed knot of connecting between pilot valve and the coil of miniature solenoid valve with use compressed air to transmit motion and power as working medium.

Background

With the introduction of modern mechanized production, the pneumatic solenoid valve is an electromechanical integrated product widely applied to the control field, and can be generally formed by assembling a main valve body, a coil and a pilot valve; the structure of the like product in the prior art has the following problems:

1. hooks at two ends of the fixing buckle are planar, no guide structure is arranged in the groove corresponding to the coil when the fixing buckle is clamped into the guide valve seat, the assembly is difficult, and the shearing type damage condition of the plastic part product is caused;

2. the fixing buckle is a metal piece, but the thickness of the material is thin and is only 0.2MM, and hooks at two ends of the structure are rigid.

Thus, the retaining clip of the prior art pilot valve also has a place to lift.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fixed knot, fixed knot is effectual connects pilot valve and coil to solve prior art's technical problem.

In order to achieve the above object, the utility model provides a fixed knot for fixed pilot valve and coil in the miniature solenoid valve, the pilot valve includes a disk seat, disk seat and coil with fixed knot lock is connected, fixed knot is a lamellar body, fixed both ends of detaining exceed 90 degrees formation lock spaces to middle crooked, fixed both ends face of detaining is the arcwall face.

According to the fixing buckle of the preferred embodiment of the present invention, a valve seat notch is formed in a position of the valve seat corresponding to a bending end of the fixing buckle, the valve seat notch includes a valve seat protrusion, and the shape of the valve seat protrusion matches with the bending shape of the bending end of the fixing buckle; the coil is provided with a coil notch at the other bent end position corresponding to the fixing buckle, the coil notch comprises a coil convex block, the shape of the coil convex block is matched with the bent shape of the bent end of the fixing buckle, and the valve seat convex block and the coil convex block are spliced to form the shape of the buckling space of the fixing buckle.

Compared with the prior art, the utility model has the advantages of it is following:

1. when the fixing buckle is clamped into the pilot valve and the coil, the two ends of the fixing buckle are guided, the assembly operability is good, the two surfaces of the fixing buckle can not be separated, and the shearing type damage condition of a plastic part product caused by assembly is reduced;

2. under the condition that the material and the material thickness are not changed, the tensile property and the rigidity of the part are enhanced, and the product is more stable and reliable.

Of course, implementing any particular embodiment of the present disclosure does not necessarily have all of the above technical advantages at the same time.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, in the present application, a schematic diagram of a fixing buckle is shown, where the fixing buckle 10 is used to fix a pilot valve and a coil in a micro electromagnetic valve, the electromagnetic valve includes a valve body (not shown), the pilot valve and the coil 30, the pilot valve includes a valve seat 20, the valve seat 20 and the coil 30 are fastened and connected by the fixing buckle 10, as shown in fig. 1, the fixing buckle 10 is a one-piece body, two ends of the fixing buckle 10 bend towards the middle by more than 90 degrees to form a buckling space 11, and the buckling space 11 is an area formed between two end surfaces 12 and a middle surface; referring to fig. 3 and 4, as shown in the figure, the two end surfaces 12 of the fixing buckle 10 are arc-shaped surfaces, and when the corresponding member is inserted into the fastening space 11, the arc-shaped surfaces form guide surfaces, so that an inserted member can smoothly slide into the fastening space 11 without generating a shearing-type damage condition; in addition, the arc-shaped surface forms stronger clamping force, and better clamping degree can be generated in the interference fit process.

Referring to fig. 5, a valve seat notch 21 is formed in a position of the valve seat 20 corresponding to a curved end of the fixing buckle 10, the valve seat notch 21 includes a valve seat protrusion 22, the shape of the valve seat protrusion 22 matches the curved shape of the curved end of the fixing buckle 10, and a surface of the valve seat 20 at a middle surface of the fixing buckle 10 in the drawing is downward and is lower than other portions of the same surface, so that the fixing buckle 10 does not protrude out of the surface of the valve seat 20 after entering, and the fixing buckle 10 is protected; the coil 30 is provided with a coil notch 31 corresponding to the other bending end of the fixing buckle 10, the coil notch 31 includes a coil bump 32, the shape of the coil bump 32 matches the bending shape of the bending end of the fixing buckle 10, and the surface of the coil 30 at the middle surface of the fixing buckle 10 in the drawing is downward and lower than other parts of the same surface, so that the fixing buckle 10 does not protrude out of the surface of the coil 30 after entering, and the fixing buckle 10 is protected.

As shown in fig. 5, the valve seat protrusion 22 and the coil protrusion 32 are combined to form the shape of the fastening space 11 of the fixing buckle 10, and when the fixing buckle 10 is assembled, the valve seat protrusion 22 and the coil protrusion 32 are combined, and the combination is an interference fit, so that the valve seat 20 and the coil 30 can be tightly fixed together.

In fig. 5, the length from the valve seat protrusion 22 to the connecting surface is different from the length from the coil protrusion 32 to the connecting surface, and the length of one side of the valve seat protrusion 22 is greater than the length of one side of the coil protrusion 32 in this embodiment, but it cannot be used to limit this application, and the length of the same length or the length of one side of the coil protrusion 32 is greater than the length of one side of the valve seat protrusion 22, so long as the connection can be secured, this application should be within the protection scope of this application.

The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
