Description

Valve inside convenient for replacing spring

Technical Field

The utility model relates to a valve inside technical field especially relates to a structural design is exquisite, be convenient for change the valve inside of spring.

Background

The valve core is installed in the main body of the valve, and the valve core is used as a one-way valve for preventing the air leakage of the inner tube, checking and adjusting the air pressure. The valve core is designed and manufactured according to the ministry-issued standard (HG 5-28-64) in a unified way, and has two types of long valve cores and short valve cores, wherein the short valve core belongs to an inner spring type, the long valve core belongs to an outer spring type, and the structure and the function of the long valve core are basically the same as those of the short valve core. The long valve inside is used in truck and industrial and mining truck, and the short valve inside may be used in other vehicles, including truck, tractor, motorcycle and trailer, as well as other vehicles.

The two ends of the core spring of the existing valve core are fixed at the two ends of the core body, so that the replacement is inconvenient, and the service life of the core spring limits the service life of the whole valve core, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a valve inside convenient to change spring, it has unique structural design, makes things convenient for the installation and the change of core spring, does not influence the normal size and the installation use of valve inside, has prolonged the life of valve inside.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

the utility model provides a valve inside convenient to change spring, includes core bar, core spring, connecting rod and bracket, its characterized in that: the core and the connecting rod are hollow cylinders with inlets and outlets at two ends respectively, the core rod penetrates through the core, the top of the bracket is provided with an inlet, the bottom end of the bracket is provided with an opening and is used for being installed on the inflating valve, the bottom end of the core rod is connected with the top end of the connecting rod in a threaded manner, the bottom end of the connecting rod is installed in the bracket, the top end diameter of the connecting rod is not larger than the diameter of the core, the bottom end diameter of the connecting rod is larger than the diameter of the core, a transition section is arranged between the top end and the bottom end of the connecting rod.

Preferably, the diameter of the transition section decreases from the top end to the bottom end.

Preferably, the core print is provided with a concave-convex part, and the spring rings at two ends of the core spring are fixed in the concave-convex part.

Due to the adoption of the technical scheme, the utility model discloses following technological effect has: the utility model discloses a set up the connecting rod between core bar and bracket, make things convenient for the installation and the change of core spring, do not influence the normal installation and the use of valve inside, and the dismouting that also can not the spring influences the gas tightness of core bar and bracket connection department, has prolonged the life of valve inside.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The valve core convenient for replacing the spring as shown in fig. 1 comprises a core rod 1, a core body 2, a core spring 3, a connecting rod 4 and a bracket 5, wherein the core body 2 and the connecting rod 4 are hollow cylinders with inlets and outlets at two ends respectively, the core rod 1 penetrates through the core body 2, the top end of the bracket 5 is provided with an inlet, a bottom opening and is used for being installed on a valve nozzle, the bottom end of the core rod 1 is in threaded connection with the top end of the connecting rod 4, the bottom end of the connecting rod 4 is installed in the bracket 5, the top end diameter of the connecting rod 4 is not larger than that of the core rod 1, the bottom end diameter is larger than that of the core body 2, a transition section 41 is arranged between the top end and the bottom end, and the bottom end outer side wall of the core.

When the core spring needs to be replaced, as the top end of the connecting rod is in threaded connection with the bottom end of the core rod, the top end of the connecting rod is only required to be separated from the bottom end of the core rod, and the core spring is reconnected after a new core spring is replaced, so that the operation is convenient. Because the bottom of connecting rod is connected with the bracket all the time, the bracket is used for being connected with the inflating valve, consequently the difficult gas tightness that destroys valve inside and inflating valve.

In this embodiment, the diameter of the transition section 41 decreases from the top end to the bottom end.

Specifically, concave-convex parts can be arranged on the core seat 6, and spring rings at two ends of the core spring 3 are fixed in the concave-convex parts, so that the core spring 3 is fixed, and the disassembly and the assembly are convenient.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
