Abstract
The utility model discloses a kind of housing structure of hand brake valve, belong to technical field of automobile parts, it comprises upper shell and lower house, two drift angle places of upper shell offer two knock holees, these two knock holees distribute along the diagonal of upper shell, the top of lower house is convexly equipped with two abutment sleeves relative with above-mentioned position of positioning hole, and upper and lower casing is connected by two binding bolts, and each binding bolt penetrates knock hole and abutment sleeve successively.The utility model structure is simple, and easy to process, cost of manufacture is low, and intensity and the right alignment of upper and lower casing are high, extend the service life of hand brake valve.
Description
Technical field
The utility model relates to a kind of hand brake valve, particularly relates to a kind of casing mechanism of hand brake valve.
Background technology
Hand brake valve has the tractor truck of brake application by spring and the braking during standstill of trailer and emergency braking for handling, hand brake valve is divided into control handle and braking valve body two parts, the control handle of hand brake valve can automatically return to road location between road location and stop position, can locking when control handle is in stop position.Specifically, when road location, hand brake valve keeps the pressure to air chamber parking spring cavity by pressure gas, and parking spring is in confined state; When parking position, the pressurized air acting on air chamber parking spring cavity is discharged, and parking spring is in free elongation state, realizes braking during standstill.Existing hand brake valve is primarily of handle, upper cover, adapter plate, upper shell, lower house, exhaust nozzle, be arranged on the cam in protective cover, balance spring, first pull back spring, second pull back spring, dummy piston and piston valve composition, wherein the assembling mode of upper shell and lower house is: upper shell offers multiple knock hole and multiple upper bolt hole, lower house offers relative with upper bolt hole position with the knock hole of upper shell respectively and the positioning convex that quantity is equal and lower bolt hole, on, lower house passes through Bolt to position, but, the casting of too much knock hole and bolt hole not only increases difficulty of processing, and can to upper, the intensity of lower house has an impact, the direct service life affecting hand brake valve.
As can be seen here, prior art awaits further improving.
Utility model content
The utility model is the weak point avoiding above-mentioned prior art to exist, and provides a kind of housing structure of hand brake valve.
The technical scheme that the utility model adopts is:
A kind of housing structure of hand brake valve, comprise upper shell and lower house, two drift angle places of upper shell offer two knock holees, these two knock holees distribute along the diagonal of upper shell, the top of lower house is convexly equipped with two abutment sleeves relative with above-mentioned position of positioning hole, upper and lower casing is connected by two binding bolts, and each binding bolt penetrates knock hole and abutment sleeve successively.
The bottom of described upper shell offers circular groove, and the top of lower house is provided with the annular projection suitable with circular groove.
The external diameter of described abutment sleeve is less than the diameter of knock hole, and the height of abutment sleeve is greater than the height of annular projection.
Owing to have employed technique scheme, the beneficial effect acquired by the utility model is:
The utility model structure is simple, and easy to process, cost of manufacture is low, and the intensity of upper and lower casing is high, extends the service life of hand brake valve; In the utility model, upper and lower casing is except realizing location between the two by binding bolt, also adopt the locate mode that circular groove matches with annular projection, ensure that the right alignment of upper and lower casing, make the up-and-down movement of dummy piston in hand brake valve more flexibly freely, be conducive to the serviceability ensureing hand brake valve.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail, but the utility model is not limited to these embodiments.
As shown in Figures 1 to 4, a kind of housing structure of hand brake valve, comprise upper shell and lower house, two drift angle places of upper shell offer two knock holees, these two knock holees distribute along the diagonal of upper shell, the top of lower house is convexly equipped with two abutment sleeves relative with above-mentioned position of positioning hole, two abutment sleeves distribute along the diagonal on lower house top, on, lower house is connected by two binding bolts, each binding bolt penetrates knock hole and abutment sleeve successively, the bottom of upper shell offers circular groove, the top of lower house is provided with the annular projection suitable with circular groove, the external diameter of abutment sleeve is less than the diameter of knock hole, the height of abutment sleeve is greater than the height of annular projection, and on, between the two without clear gap after lower house assembling, avoid entering of dust.
The part do not addressed in the utility model adopts or uses for reference prior art and can realize.
Specific embodiment described herein is only to spiritual example explanation of the present utility model.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
