Abstract

The utility model relates to an aerating device specifically is an automobile tire aerifys pole. Including the circle tubular rod body, the screw is made along outer circumference to circle tubular rod body one end, and hook -like structure is made to the other end, and the body of rod endocyst of hook -like structure free end contains valve inside top, rubber circle, and the rubber circle connects the valve inside top through its central borehole jack and impresses in the body of rod of hook -like structure free end, leave at valve inside top middle part has the air channel. Because the screw is processed into along outer circumference to body of rod one end, hook -like structure is made to the other end to hook -like physical end stretches into that the rim is downthehole to be entangled that the valve inside is inflated the tire and do not take place to interfere with the rim, at body of rod one end processing screw thread to realize with ordinary pump articulate, could realize inflating to the tire, so the hook -like formula automobile tire aerifys pole of this kind have not only solved the foreign steamer problem of inflating behind the automobile well, but and also the vehicle -mounted carry, very conveniently oversimplify with implementing.

Description

A kind of automobile tyre inflation bar

Technical field

The utility model is related to a kind of aerating device, specially a kind of automobile tyre inflation bar.

Background technology

Most of commercial back wheels of vehicle is twin tyre, and rear foreign steamer valve cock cannot be inflated because being blocked by wheel rim, it has to Wheel rim is drawn on trailing wheel using valve cock lengthened hose to be inflated, as shown in Figure 1 so that wheel amount of unbalance increases, can Decline by property；And when being inflated using valve cock on rear foreign steamer 11, also need additionally to increase other devices, for example, increase pipe Valve cock installs lengthened hose 33 additional on folder 22, valve cock lengthened hose 33, fixed support 44, therefore the rear wheel rim of foreign steamer 11, also not It is convenient, and aerating device also seems relative complex.

The content of the invention

The purpose of this utility model is：For the problem that above-mentioned prior art is present, a kind of automobile tyre inflation is proposed Bar, the utility model can enable the inflation lengthened hose of rear tire cancel, and easily rear foreign steamer cover tire is filled Gas and reduce wheel unbalancing value.

In order to reach object above, a kind of automobile tyre inflation bar of the present utility model, including the circular tube shaped body of rod, its feature It is：Screw thread is made in described circular tube shaped body of rod one end along excircle, and the other end makes hook formation, the bar of hook formation free end In vivo comprising valve inside top, rubber ring, rubber ring connects valve inside and comes directly towards and be pressed into hook formation freedom by its center borehole jack In the body of rod at end；Valve inside top middle part is provided with air channel.

Further, the hook formation angle of bend scope is 20 ° -24 °.

Further, hook formation free end external diameter of rod body is φ 10.6mm, and its internal diameter is φ 7.8mm.

Further, a diameter of 4-5mm scopes of inner circle that the hook formation bend is constituted, its bend is laterally Extend a length of 28-35mm scopes.

Further, screw thread is 8V1 type GB9765-1997 screw threads on the circular tube shaped body of rod, and its reach is 9- 10mm scopes.

Further, the circular tube shaped body of rod adopts copper material.

The beneficial effects of the utility model：Because screw thread, other end system are processed in circular tube shaped body of rod one end along excircle Into hook formation, valve inside is entangled in wheel rim hole tire is inflated and does not occur with wheel rim dry so that hook-shaped termination is stretched into Relate to；After circular tube shaped body of rod one end processes screw thread, to realize being connected with common inflation pump joint, you can to tyre inflating, because This this hook formation formula automobile tyre inflation bar not only solves well foreign steamer after automobile and is inflated problem, and also may be used Onboard, very convenient and enforcement simplification.

Specific embodiment

Embodiment one

A kind of automobile tyre inflation bar of the utility model, its structure as shown in Figure 2-5, including the circular tube shaped body of rod 1, circular tube shaped Screw thread is made in the one end of the body of rod 1 along excircle, and the other end makes hook formation, and gas is included in the body of rod of hook formation free end 111 Door core top 2, rubber ring 3, rubber ring 3 connects valve inside top 2 and is pressed into hook formation free end 111 by its center borehole jack In the body of rod；The middle part of valve inside top 2 is provided with air channel 4.Specifically：Valve inside top 2 after the embedded center hole of rubber ring 3 simultaneously It is pressed in the body of rod of hook formation free end 111, as shown in Figure 2,3 with rubber ring 3；In addition above-mentioned rubber ring 3 is used to fit Valve mouthpiece, to realize end face seal when inflating, the middle part of valve inside top 2 is provided with air channel 4, as shown in Figure 4；When backing down wheel Allow compressed air to enter tire by valve inside top 2 and valve inside while tyre valve core, realize the inflation to tire.

In the utility model implementation process：Hook formation angle of bend scope is 20 ° -24 °, in the present embodiment, hook Shape structural bending angle adopts 22 °, and preferably with copper material, hook formation free end external diameter of rod body is φ to the circular tube shaped body of rod 1 10.6mm, closely to insert valve inside top 2 in the body of rod of hook formation free end, on valve inside top 2 rubber ring 3 is installed additional, Body of rod internal diameter in hook formation free end is φ 7.8mm, a diameter of 4-5mm scopes of inner circle that hook formation bend 112 is constituted, Its bend 112 extends laterally a length of 28-35mm scopes；In the present embodiment, what the bend 112 of hook formation was constituted is interior Circular diameter also optional 4mm, bend 112 extends laterally a length of 33mm；In addition, screw thread is 8V1 types on the circular tube shaped body of rod 1 GB9765-1997 screw threads, its reach is 9-10mm scopes, to connect source of the gas, realizes connecting with common inflation pump joint Connect.

When needing to be inflated to rear tire, the external screw thread of automobile tyre inflation bar one end is screwed in inflation pump joint On screw thread, then dust cap on tire is backed out, automobile inflating bar hook formation is stretched into into wheel rim hole, its head is inserted in into valve Mouth, you can automobile tire is inflated, whole implementation state, as shown in Figure 5, it is clear that the automobile tyre inflation bar and reality Apply all very simple, without the need for configuring, installing additional support or pipe clamp.

Compare in prior art Fig. 1, not only need to use valve cock lengthened hose 33, it is solid without installing additional on wheel rim Fixed rack 44, pipe clamp 22；If onboard automobile tyre inflation bar, therefore, the utility model automobile tyre inflation bar is very square Convenient to operate.

The utility model when making, not only process is simple, cost of manufacture is also very low, therefore is worthy of promotion and application.

In addition to the implementation, the utility model can also have other embodiment.All employing equivalents or equivalent change The technical scheme to be formed is changed, the protection domain of the utility model requirement is all fallen within.
