Abstract

The utility model provides an outer locking connection type structure of a spoke of a wheel rim, which enables a type not to be affected after the spoke and the wheel rim are fixedly connected. The peripheral surface of the wheel rim is mainly kept smooth, both sides of the wheel rim are outwards extended with two flanges respectively, and the flanges are fixedly connected with the end sides of the spoke after supported by a plurality of locking and connecting posts. So long as the locking and connecting posts are fixedly connected with the end sides of the spoke, the smooth wheel rim can be separated from the spoke fully after the smooth wheel rim is inlaid with the tyre. The utility model can avoid the abrasion caused by the contact of the spoke and the tyre. Besides, when the spoke is disassembled and replaced, the assembly and the disassembly of the type are not needed, so the utility model can be suitable for high-speed tyres better and can improve the convenience and practicality of use greatly.

Description

Wheel rim spoke external lock eliminant structure

The utility model relates to a kind of wheel rim spoke external lock eliminant structure, is meant that especially a kind of wheel rim spoke external lock eliminant that does not influence tire after making spoke and wheel rim fixed constructs.

Bicycle is the lightest at present, low consumption volume, the vehicle that meet the environmental protection demand again, therefore, with bicycle as the vehicle of riding instead of walk or replacing midway, even in order to leisure, body-building, widely people accept, and the customer is in the requirement of using, except the structural safety of strengthening vehicle body, traveling comfort and ease of use when driving are also more and more paid attention to.

As shown in Figure 1, with existing the affixed of wheel is example, it is mainly 3 of the colored hub 2 of wheel shaft 1 and wheel rims, connected to count spoke 4, inside and outside tire 501,502 for tire 5 is embedded in wheel rim 3 peripheries, and this wheel rim 3 is provided with number perforation 301 at the corresponding spoke of side face 4 places, is worn to periphery by wheel rim 3 inner faces for spoke 4 distolateral screw threads 401, is screwed togather fixing with a nut 6; Though above-mentioned structure can reach the purpose of affixed spoke 4 and wheel rim 3, when its actual use, still exists following defective to need to be resolved hurrily:

That is, because spoke 4 and wheel rim 3 when affixed, must be provided with perforation 301 earlier at wheel rim 3 side faces, could supply spoke 4 to pass, be spirally connected, reach the purpose of fixed spoke 4 with nut 6 and spoke 4, be positioned at nut 6 under the situation of 501 in wheel rim 3 side faces and tire 5 inner tubes of a tyre, this spoke 4 also must unload tire 5 earlier if will change the outfit, and just can appear nut 6, therefore, in quite inconvenience of fit on, and have a strong impact on the comfort feature in when assembling, and do not meet user demand.

The purpose of this utility model then is the problem that exists at above-mentioned prior art, provide a kind of can make smooth wheel rim and tire chimeric after, the wheel rim spoke external lock eliminant that does not contact with spoke is fully constructed.

The purpose of this utility model can reach by following measure:

A kind of wheel rim spoke external lock eliminant structure mainly is between the colored hub and wheel rim of wheel shaft, is connected to count spoke, is embedded in the wheel rim periphery for tire; It is characterized in that: this wheel rim makes side face keep smooth, and its both sides have extended a flange respectively outwardly, and is after the bearing of number interlocking post, distolateral affixed with spoke.

So, need only utilize interlocking post and spoke distolateral affixed, can make smooth wheel rim and tire chimeric after, do not contact fully with spoke; The utility model can avoid spoke to contact abrasion with tire, and also need not load and unload tire when changeing spoke, more can be suitable for performance tires, and can significantly promote comfort feature and practicality in the use.

The utlity model has following advantage:

One, owing to the flange 24 bearing interlocking posts 25 of wheel rim 20 of the present utility model by both sides, make interlocking post 25 and bar spoke 30 reach affixed purpose, thereby all can be smooth shape at the inside and outside side face 22,23 of wheel rim 20, under the situation that the spoke 30 and the inner tube of a tyre 41 of tire 40 are isolated fully, no matter tire 40 is in the process of advancing, how to compress, bounce, can not have abrasion of contacting or impaired situation to produce, so as to service life that promotes tire 40 and the practicality of using with spoke 30.

Two moreover, this spoke 30 directly is locked in the interlocking post 25, and interlocking post 25 is emerging in flange 24 end faces of wheel rim 20 both sides, therefore, when changing the outfit, directly pine oil nut 253 gets final product, and need not unload tire 40, the utility model is quite easy at fit on, and can significantly promote the comfort feature when assembling, to meet user demand.

Three, the inside and outside side face 22,23 at wheel rim 20 is smooth shape, can not have under the situation in any hole and slit, and this wheel rim 20 also can directly be suitable for general performance tires 50, and the setting of the inner tube of a tyre must not be arranged, and makes the utility model more extensive on applicability.

Below in conjunction with accompanying drawing the utility model is further described:

Shown in Fig. 3,4,5, the utility model mainly is 20 of the colored hub 11 of wheel shaft 10 and wheel rims, is connected to count spoke 30, is embedded in the caulking groove 21 of wheel rim 20 peripheries for the inside and outside tire 41,42 of tire 40; Wherein, members such as this wheel shaft 10, wheel rim 20 and spoke 30 are existing, so no longer its detailed construction and action are described at this, below are illustrated at feature of the present utility model:

This wheel rim 20 as shown in Figure 6, make inside and outside side face 22,23 all keep smooth, extended a flange 24 respectively outwardly in both sides, make flange 24 be provided with a perforation 241 respectively at corresponding spoke 30 distolateral thread segment 31 places, supply 25 bearings of number interlocking post at flange 24 end faces, and this interlocking post 25 vertically is provided with a perforation 251, connects perforation 251 places at end face and is provided with a groove 252, and is ccontaining for a nut 253.

The utility model assembled condition is shown in Fig. 4,6, spoke 30 1 ends need only be passed in regular turn flange 24 perforation 241 of wheel rim 20 both sides, thread segment 31 is set in the perforation 251 of interlocking post 25, at last, screw togather locking with nut 253 and thread segment 31 again, make spoke 30 and wheel rim 20 finish affixed in regular turn.

Under wheel rim 20 inside and outside side faces 22,23 all keep smooth situation, after making the caulking groove 21 of tire 40 and wheel rim 20 chimeric, its inner tube of a tyre 41 does not have any contacting with spoke 30 fully, and can be because of compression, the spring of tire 40, the situation that the contact abrasion inner tube of a tyre 41 is arranged is so as to service life that promotes tire 40 and the practicality of using.

In addition, as shown in Figure 7, because the inside and outside side face 22,23 of this wheel rim 20 is smooth shape, any hole and slit can be do not had, therefore, also general performance tires 50 can be directly be suitable for, and the setting of the inner tube of a tyre must not be arranged, can be directly chimeric by wheel rim 20 and performance tires 50, reach the air tight effect, make the utility model more extensive on applicability.
