Abstract
The utility model discloses a caster connected with a hollow vertical shaft. The caster comprises a caster body, a caster beam disc, a caster bracket, a caster tyre, the hollow vertical shaft and a transverse shaft, wherein the caster tyre is riveted on the caster bracket through the transverse shaft; and the hollow vertical shaft passes through the caster bracket and the caster bead disc sequentially and then is riveted on the caster body. According to the caster connected with the hollow vertical shaft, the hollow vertical shaft which is manufactured through punching forming of plates is provided, so the whole weight of the caster is reduced, the dimensional precision is high and the cut is regular. The caster connected with the hollow vertical shaft has a simple and compact structure, the caster body and the caster bracket are connected stably through the hollow vertical shaft, and the hollow vertical shaft can effectively reduce high temperature caused by rotation of the caster bracket, so that the service life of the caster is prolonged.
Description
Technical field
The utility model relates to the case and bag technical field, relates in particular to the castor that a kind of hollow vertical shaft connects.
Background technology
Vertical shaft is a vitals for support and connection case and bag body and bottom tire, and it is all larger that it is subjected to vertically to reach lateral stress when using.Therefore, for guaranteeing its structural strength, it is to adopt traditional Cold header to process with the filled circles wire material that existing castor connects with vertical shaft, and the vertical shaft that this processing technology is produced is solid shafting, and weight is heavier, and dimensional accuracy is not high, and tail cant is uneven.
The utility model content
For the weak point that exists in above-mentioned technology, the utility model provides a kind of lightweight, dimensional accuracy is high and otch is neat castor that hollow vertical shaft connects.
For achieving the above object, the castor that the utility model provides a kind of hollow vertical shaft to connect, comprise castor body, castor pearl dish, trundle bracket, castor tire, hollow vertical shaft and transverse axis, described castor tire is riveted on trundle bracket by transverse axis, and described hollow vertical shaft is riveted on the castor body after passing successively trundle bracket and castor pearl dish.
Wherein, described castor also comprises pad, and described hollow vertical shaft is riveted on pad after passing successively trundle bracket, castor pearl dish and castor body.
Wherein, the diameter of close castor body one end of described hollow vertical shaft is less than the diameter near trundle bracket one end.
The beneficial effects of the utility model are: compared with prior art, the castor that the hollow vertical shaft that the utility model provides connects by the hollow vertical shaft that utilizes the plate stamping moulding to make is set, has alleviated the overall weight of castor, and dimensional accuracy is high and otch is neat.Simultaneously, of the present utility model simple and compact for structure, firmly connect castor body and trundle bracket by a hollow vertical shaft, hollow vertical shaft can effectively reduce the high temperature that produces because of the trundle bracket rotation, thus the service life of improving castor.
Description of drawings
Fig. 1 is the cutaway view after the decomposition of the castor that connects of hollow vertical shaft of the present utility model;
Fig. 2 is the cutaway view after the assembling of the castor that connects of hollow vertical shaft of the present utility model.
The main element symbol description is as follows:
10, castor body 11, castor pearl dish
12, trundle bracket 13, castor tire
14, hollow vertical shaft 15, transverse axis
16, pad
The specific embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is done to describe further.
See also Fig. 1 and Fig. 2, the castor that the hollow vertical shaft that the utility model provides connects, comprise castor body 10, castor pearl dish 11, trundle bracket 12, castor tire 13, hollow vertical shaft 14 and transverse axis 15, castor tire 13 is riveted on trundle bracket 12 by transverse axis 15, and hollow vertical shaft 14 is riveted on castor body 10 after passing successively trundle bracket 12 and castor pearl dish 11.
Compared to the situation of prior art, the castor that the hollow vertical shaft that the utility model provides connects by the hollow vertical shaft that utilizes the plate stamping moulding to make is set, has alleviated the overall weight of castor, and dimensional accuracy is high and otch is neat.Simultaneously, of the present utility model simple and compact for structure, firmly connect castor body and trundle bracket by a hollow vertical shaft, hollow vertical shaft can effectively reduce the high temperature that produces because of the trundle bracket rotation, thus the service life of improving castor.
In the present embodiment, above-mentioned castor also comprises pad 16, and hollow vertical shaft 14 is riveted on pad 16 after passing successively trundle bracket 12, castor pearl dish 11 and castor body 10.Certainly; this case is not limited to a pad 16 only is set; cushion the joint face of hollow vertical shaft 14 and castor body 10; the joint face of the hollow vertical shaft 14 of another pad buffering and trundle bracket 12 also can be set; so long as utilize hollow vertical shaft firmly to connect castor body 10 and trundle bracket 12; reduce the weight of vertical shaft and can reduce the embodiment that rotates the high temperature that produces because of trundle bracket 12, all drop into the protection domain of this case.
In the present embodiment, the diameter of above-mentioned hollow vertical shaft 14 close castor body 10 1 ends is less than the diameter near trundle bracket 12 1 ends.Certainly; this case is not limited to up-small and down-big structure; also can be up big and down small structure; as long as utilize hollow vertical shaft firmly to connect castor body 10 and trundle bracket 12; reduce the weight of vertical shaft and can reduce the embodiment that rotates the high temperature that produces because of trundle bracket 12, all drop into the protection domain of this case.
Advantage of the present utility model is:
1. vertical shaft weight before improving: 15 grams, vertical shaft 5 grams after improving calculate light 40 grams of each case and bag with 4 castors of each case and bag.
2. this advances rear hollow vertical shaft and can utilize central through hole accurately to locate riveted joint, improves end product quality and product qualified rate.
3. hollow shaft can effectively reduce the high temperature that produces because of support rotation, thereby improves castor service life.
Above disclosed be only several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
