Abstract
The utility model discloses an air pressure meter and valve body connecting structure for a load switch. A clamping spring is arranged at the position of a connecting hole in the upper portion of a valve body. The clamping spring comprises a straight line portion and a camber line portion which are mutually connected. The straight line portion is inserted into the connecting hole. The end portion of the camber line portion of the clamping spring is provided with an upward bend. The end portion of the straight line portion is provided with a downward bend. Two grooves are formed in the upper portion of the valve body. The two bends are attached to the interiors of the two grooves respectively. A clamping groove is formed in an inserted connection part of the lower portion of an air pressure meter. The inserted connection part is inserted into the connecting hole. The straight line part of the clamping spring is clamped into the clamping groove. Connection between the air pressure meter and the valve body can be rapidly achieved, and rotation of the air pressure meter can be guaranteed.
Description
Technical field
The utility model relates to a kind of on-load switch parts, relates in particular to a kind of on-load switch barometer and joint structure connecting valve.
Background technique
On-load switch of the prior art (SMC1) barometer used and valve body Placement are unreliable, installation time is long, have the phenomenon such as assembled portion gas leakage.
As shown in Figure 1 and Figure 2, on barometer 3, be with a removable bolt 4, the barometer end had in the attachment hole 2 in the partial insertion valve body 6 of seal ring 5, then the internal thread of removable bolt 4 is screwed in the outside thread 1 of valve body 6, realize connecting.Complete after connection barometer as shown in Figure 3.
There is following shortcoming at least in above-mentioned prior art:
Screw thread on removable screw thread and valve body is fixed, and has so just caused barometer and valve body to be completely fixed, and barometer is non-rotatable, so after installation, can not guarantee that barometer is positive; And be threaded connection, be screwed in process at barometer, rubber ring is easy to wear, so that affect barometric sealability, cause gas leakage; And need certain hour being threaded into, reduced installation rate.
The model utility content
The purpose of this utility model is to provide that a kind of Placement is reliable, installation time is short, the on-load switch of good airproof performance is with barometer and joint structure connecting valve.
The purpose of this utility model is achieved through the following technical solutions:
On-load switch of the present utility model is with barometer and joint structure connecting valve, its preferably embodiment be:
Connection hole on valve body top is provided with jump ring, described jump ring comprises interconnective straight section and camber line part, described straight line position extend in described attachment hole, plugging position in the barometer bottom is provided with draw-in groove, described plugging position is inserted in described attachment hole, and the straight section of described jump ring snaps onto in described draw-in groove.
By the technological scheme that above-mentioned the utility model provides, can be found out, the on-load switch that the utility model embodiment provides barometer and joint structure connecting valve, because the connection hole on valve body top is provided with jump ring, jump ring comprises interconnective straight section and camber line part, the straight line position extend in described attachment hole, plugging position in the barometer bottom is provided with draw-in groove, plugging position is inserted in attachment hole, the straight section of jump ring snaps onto in draw-in groove, barometer and being connected of valve body are realized fast, Placement is reliable, installation time is short, good airproof performance, and can guarantee that barometer is rotatable.

Embodiment
Below will be described in further detail the utility model embodiment.
On-load switch of the present utility model is with barometer and joint structure connecting valve, its preferably embodiment be:
Connection hole on valve body top is provided with jump ring, described jump ring comprises interconnective straight section and camber line part, described straight line position extend in described attachment hole, plugging position in the barometer bottom is provided with draw-in groove, described plugging position is inserted in described attachment hole, and the straight section of described jump ring snaps onto in described draw-in groove.
The end of described jump ring camber line part is provided with bending upwards, the end of straight section is provided with downward bending, and the top of described valve body is provided with two grooves, and two bendings are pasted into respectively in two grooves.
Described draw-in groove is annular slot.
The plugging position of described barometer bottom is provided with seal ring.
By the utility model, barometer and being connected of valve body are realized fast, and can guarantee that barometer is rotatable.
Specific embodiment:
As shown in Fig. 4 a, Fig. 4 b, Fig. 5 a, Fig. 5 b, Fig. 6 a, Fig. 6 b, on valve body 6 tops, connect a jump ring 7, one end of jump ring 7 is that straight section, the other end are the camber line part, the end of jump ring 7 is provided with bending, the bending 8 of camber line part end makes progress, the bending 9 of straight section end is downward, jump ring 7 sticks into the top of valve body 6, by two bendings, fix, bending 8 upwards is pasted in the groove 10 of Self-sealing valve, downward bending 9 is pasted in the groove 11 that valve body lower portion divides, and jump ring 7 just links together with valve body 6 like this.Now the straight section of jump ring 7 enters in the attachment hole on valve body 6 tops.
As shown in Figure 7, Figure 8, the end of barometer 3 is provided with seal ring 5 and draw-in groove 12, when barometer and valve body assembling, only barometer 3 ends need be had in the attachment hole on partial insertion valve body 6 tops of seal ring, the downward bending 9 of jump ring 7, due to the effect meeting of pressure side shifting outward, snaps in barometric draw-in groove 12, now until jump ring 7 enters the straight section of Self-sealing valve the inside, barometer 3 is fixed by jump ring 7, and assembling completes.While unloading, the downward bending 9 of jump ring 7 toward the outside, break into two with one's hands straight section that jump ring 7 enters valve body 6 from the draw-in groove 12 of barometer 3 out, at this moment can pull up barometer 3.
Because this connects by jump ring, snap in and complete in barometric draw-in groove, thus barometer can be in groove random translation-angle, so just can guarantee that no matter what angle barometer valve and valve body are, can realize that the air pressure gauge outfit is positive by rotating barometer.
The Placement of barometer and valve body adopts structure of the present utility model, not only cost-saving, assembling applies greatly to be shortened, and compares more economical with former mounting type, and barometer can freely rotate in valve body, avoided the not positive situation of the barometer gauge outfit produced in original assembling.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
