Abstract
The utility model discloses a kind of gas spring with low pressure needle structure, including valve component, the valve component includes valve body, needle, spacer and button, the spacer is installed in the cavity of valve body, the needle is also cross valve body and spacer, the needle includes sealing catch and straight rod type needle body, described straight rod type needle body one end is fixedly connected with sealing catch, the other end is provided with external screw thread, the button is flat metal member, one side surface is smooth, opposite side has blind hole, the blind hole has the internal thread being adapted with straight rod type needle body, the needle is threadedly coupled with button.The gas spring, its assembling process has remained in that the mounting means of traditional straight rod type needle body, last again need to only be connected through a screw thread button and valve needle terminal end fastens, you can effectively increase the contact area of valve needle terminal end, the pressure for the part that reduction needle is adapted to periphery.
Description
Technical field
The utility model is related to gas spring technology field, particularly a kind of gas spring with low pressure needle structure.
Background technology
The lower end of traditional gas spring can match somebody with somebody the startup bar assembly for being ready for use on jack-up needle, and valve body and startup bar assembly one
Rise and be wrapped in standpipe so that user can only manipulate valve element by started by press bar assembly.Because some are new, small-sized
The gas spring of change needs to reduce spring volume as far as possible in the case where keeping equal elastic force, therefore startup bar assembly will be small by this
Type gas spring system is excluded, i.e., valve body can be arranged on the end in the small-sized gas spring after improving.No matter traditional structure or
Novel structure, its needle uses the structure of identical single-side sealing baffle structure straight rod type needle body, because straight rod type pin
Body can be easily also cross the spacer in valve body and valve body.But, due to straight rod type needle body distal end faces area compared with
It is small, very big pressure can be produced to matching part in use, easily workpiece is damaged, product failure.
Utility model content
The utility model provides a kind of gas spring with low pressure needle structure, and its valve needle terminal end has larger contact
Area, produced pressure when can effectively reduce it with other feature contacts.
Gas spring with low pressure needle structure, including valve component, the valve component include valve body, needle, every
Set and button, the spacer are installed in the cavity of valve body, and the needle is also cross valve body and spacer, and the needle includes close
Block piece and straight rod type needle body, described straight rod type needle body one end are fixedly connected with sealing catch, and the other end is provided with external screw thread, described
Button is flat metal member, and a side surface is smooth, and opposite side has blind hole, and the blind hole has to be adapted with straight rod type needle body
Internal thread, the needle is threadedly coupled with button.
Further, the valve body surface has at least one air drain being radially arranged, the air drain close to the side of button
The edge of valve body is extended to by the through hole of needle through valve body.
The disclosed gas spring with low pressure needle structure of the utility model, its assembling process has remained in that traditional
The mounting means of straight rod type needle body, last again need to only be connected through a screw thread button and valve needle terminal end fastens, you can effectively increase
The contact area of big valve needle terminal end, the pressure for the part that reduction needle is adapted to periphery.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings

Fig. 1 is the view in full section of valve component described in the utility model.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to constitute more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
As shown in figure 1, the gas spring with low pressure needle structure, including valve component, the valve component includes valve
Body 1, needle 2, spacer 3 and button 4, the spacer 3 are installed in the cavity of valve body 1, and the needle 2 is also cross the He of valve body 1
Spacer 3, the needle 2 includes sealing catch 21 and straight rod type needle body 22, described one end of straight rod type needle body 22 and sealing catch 21
It is fixedly connected, the other end is provided with external screw thread, and the button 4 is flat metal member, and a side surface is smooth, and opposite side has blind
Hole, the blind hole has the internal thread being adapted with straight rod type needle body 22, and the needle 2 is threadedly coupled with button 4.
As further preferred embodiment, the surface of valve body 1 has at least one radially close to the side of button 4
The air drain 11 of setting, the air drain 11 is extended to the edge of valve body 1 by the through hole of needle 2 through valve body 1.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
