Abstract

The utility model discloses a rotatable valve structure which comprises a fixed frame, a valve and a pressure plate, wherein a ratchet wheel is arranged on the tail end of the valve, a pawl is arranged on one surface of the pressure plate, the side wall of the valve and two sides of the pressure plate are all hinged with the fixed frame, the ratchet wheel at the tail end of the valve and the pawl of the pressure plate are relatively arranged, an elastic sheet is also fixedly arranged on the fixed frame, and the elastic sheet bounces up and down the other surface of the pressure plate so that the pawl and the ratchet wheel are meshed. By adopting the valve with the ratchet wheel structure, so that the angle of the installed valve can be adjusted, in practical use, the valve can be applicable to hubs of various models, and compared with existing valve structure, the rotatable valve structure has the advantages of being strong in applicability, beneficial to production and manufacturing, and convenient to operate and use.

Description

Rotatable inflating valve structure

Technical field

The utility model relates to wheel hub tire tube valve accessory technical field, is specifically related to a kind of rotatable inflating valve structure.

Background technology

Existing wheel hub especially automotive hub because hub type is different, also there is corresponding difference in the design angle of tire tube valve, therefore, in manufacturing process, when needs are changed a kind of wheel hub type, the angle of tire tube valve also will be changed thereupon, and the design cost and the processing charges that bring thus also increase.And in actual use, because tire tube valve angle is fixed, tend to bring operational inconvenience.

Utility model content

The utility model provides a kind of rotatable inflating valve structure, can address the above problem.

A kind of rotatable inflating valve structure that the utility model embodiment provides, comprise: fixed mount, tail end are provided with the tire tube valve of ratchet and the pressing plate that one side is provided with ratchet, tire tube valve sidewall and pressing plate dual-side are all hinged on fixed mount, and the ratchet of tire tube valve tail end and the ratchet of pressing plate are oppositely arranged, fixed mount is fixed a shell fragment on also, and the another side that shell fragment suppresses pressing plate makes ratchet and ratchet engagement.

Preferably, also comprise a sensor for detection of tire pressure, described fixed mount is fixed on sensor.

Preferably, described pressing plate is the arc mating with tire tube valve tail end, and arc intrados is provided with ratchet.

Preferably, described shell fragment is embedded on fixed mount, and the one side that shell fragment contacts with pressing plate is cambered surface.

Technique scheme can be found out, because the utility model embodiment adopts the tire tube valve with ratchet structure, make tire tube valve still can adjust angle after installing, therefore, in actual practicality, can be applicable to the wheel hub of various models, with respect to existing inflating valve structure have applicability strong, be conducive to manufacture the advantage that convenient operation is used.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the decomposition texture schematic diagram of the utility model embodiment inflating valve structure;

Fig. 2 is the package assembly schematic diagram of the utility model embodiment inflating valve structure.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

The utility model embodiment provides a kind of rotatable inflating valve structure, shown in Fig. 1 and Fig. 2, comprise: fixed mount 1, tail end are provided with the tire tube valve 2 of ratchet and the pressing plate 3 that one side is provided with ratchet, tire tube valve 2 sidewalls and pressing plate 3 dual-sides are all hinged on fixed mount 1, and the ratchet of tire tube valve 4 tail ends and the ratchet of pressing plate 3 are oppositely arranged, fixed mount 1 is fixed a shell fragment 4 on also, and the another side (with the one side of ratchet) that shell fragment 4 suppresses pressing plate 3 makes ratchet and ratchet engagement.

In the present embodiment, inflating valve structure, also with sensor, also comprises a sensor for detection of tire pressure, and described fixed mount 1 is fixed on sensor.As can be seen here, the shell of this sensor can be held concurrently and be used as fixed mount, to save consumptive material, reduces space hold.Certainly, at other, do not have under the situation of sensor, set separately fixed mount or serve as fixed mount with other fixed sturctures in wheel hub and also can.

For the ease of the restriction to tire tube valve rotational angle, control, described pressing plate 3 is the arc mating with tire tube valve 2 tail ends, and arc intrados is provided with ratchet.Be appreciated that because tire tube valve tail end adopts ratchet structure, certainly exist arc surface, so the present embodiment is also designed to arc by pressing plate, can guarantee that ratchet and ratchet have more area of engagement, increase the stability of adjusting control.

For the ease of operation shell fragment, shell fragment described in the present embodiment 4 is embedded on fixed mount 1, and the one side that shell fragment 4 contacts with pressing plate 3 is cambered surface.Be that the extrados of shell fragment is relative with the extrados of pressing plate, form the structure of " dos-à-dos ", reduced the area of contact of shell fragment and pressing plate, in the swing process of pressing plate, further reduced friction drag, and can form larger space at shell fragment and pressing plate two ends, convenient operation person pulls shell fragment with hand.

Under normal circumstances, due to the elastic force effect of shell fragment, pressing plate is suppressed the tail end at tire tube valve, make ratchet and ratchet engagement, the direction that now operator can only comply with ratchet is pulled tire tube valve, thereby adjusts angle, if will adjust in the opposite direction tire tube valve angle, operator need to pull open shell fragment, make shell fragment no longer to pressing plate, apply elastic force, and the disengaging of the ratchet on crush board ratchet, now, operator can pull tire tube valve in the opposite direction, thereby adjusts the angle of tire tube valve.

For inner structure and the principle of work of tire tube valve, those skilled in the art can be known by prior art, repeat no more herein.

A kind of rotatable inflating valve structure above the utility model embodiment being provided is described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand core concept of the present utility model; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
