Abstract
The utility model discloses a novel wheel set structure of a trundle of a PC/ABS hard shell suitcase. The novel wheel set structure comprises a bracket, an annular gasket, balls, a wheel leg, a rolling wheel and a screw, wherein a first annular groove is formed in one side of the bottom surface of the bracket, a second annular groove is formed in the bottom surface of the first annular groove, the first annular groove and the second annular groove are arranged in a concentric mode, a third annular groove is formed in the end face of the wheel leg, a second through hole is formed in the center of the circle of the third annular groove, the end face of the wheel leg is sleeved with the first annular groove in a rotary mode, the annular gasket is movably embedded into the first annular groove, a plurality of ball installing holes are formed in the annular gasket in the circumferential direction, the screw penetrates through the second through hole, a center hole of the annular gasket and a first through hole in sequence, the root portion of the screw is tightly locked through a nut. According to the novel wheel set structure of the trundle of the PC/ABS hard shell suitcase, due to the facts that the annular gasket and the balls are arranged, and the annular gasket and the balls are fixed together through the screw, installation is easy and convenient; due to the fact that the bracket and the annular gasket are formed by plastic, when the universal wheel, namely the trundle, is used, and makes contact with water, the bracket and the annular gasket cannot rust, and the trundle is durable; due to the fact that the plastic is light in weight, a user can feel light when using the trundle.
Description
Technical field
The utility model relates to Castor for trunk or bag field, particularly a kind of wheel group structure of novel PC/ABS hard shell trunk castor.
Background technology
Case and bag are necessary articles of whilst on tour, current luggage mostly is slidably case and bag of rod-pulling type, more laborsaving, case and bag realization is mainly slidably to realize by the castor of case and bag bottom, castor is so-called cardan wheel, and its structure allows 360 ° of rotations of level, and the ubiquitous problem of castor is with after a period of time at present, show rolling dumb, and easily come off.Inflexible major cause of rolling be the wheels of castor the inside by metal forming, not only get rusty easily and heavy, cost is also higher; Castor holds caducous reason, and castor is fixed on inclusion and fixes by bracket, and miscellaneous part is connected with caster, between caster and bracket, be bolted together by double layer of metal pad and one deck pourable resin chock, because there are three layers of pad inside, casing used after the long period, careless slightly, can cause pad to come off, in addition, the caster of case and bag is many by metal forming at present, in the time of the portable case and bag of needs, heavier, and metal material gets rusty easily, and affects the service life of case and bag.
Summary of the invention
The purpose of this utility model is to provide a kind of novel simple in structure, difficult drop-off, be difficult for getting rusty and the wheel group structure of durable PC/ABS hard shell trunk castor.
For achieving the above object, the utility model is by the following technical solutions:
A kind of wheel group structure of novel PC/ABS hard shell trunk castor, it comprises bracket, annular gasket, ball, caster, roller and screw, described roller is rotatably connected on the bottom of caster; Bottom surface one side of described bracket is provided with first ring connected in star, and the bottom surface of first ring connected in star is provided with the second concentric annular groove, and first ring connected in star circle centre position is provided with the first through hole; The second annular groove on the corresponding bracket of end face of described caster is provided with the 3rd annular groove, described the 3rd annular groove circle centre position is provided with second through hole corresponding with the first through hole, outside the end face of described caster, turning set is located on the first ring connected in star of bottom surface one side of bracket, described annular gasket activity is embedded in described first ring connected in star, on annular gasket, edge is circumferentially with multiple ball mounting holes, described ball activity is embedded in described ball mounting hole, and the outer wall of ball is resisted against the diapire of the second annular groove and the 3rd annular groove; Described screw sequentially passes centre hole and first through hole of the second through hole, annular gasket, and by the root locking of nut and screw, bracket, annular gasket, caster is linked into an integrated entity.
Described annular gasket is by plastic shaping, and the annular gasket of plastic shaping not only quality is light, and withstanding corrosion, is difficult for getting rusty causing cardan wheel to come off or dumb.
Described bracket is by plastic shaping, and quality is light and be difficult for getting rusty, and in the time that needs are being carried case and bag, can not bring too many extra weight.
Two surfaces up and down of described annular gasket and be equipped with hemispheric projection between every adjacent two ball mounting holes, hemispheric projection, its effect is the same with ball, can help to realize the rotation of caster.
Described projection and ball mounting hole are distributed in same circumferential line.
PC/ABS refers to polycarbonate and acrylonitrile-butadiene-styrene copolymer and compound.
The wheel group structure of a kind of novel PC/ABS hard shell trunk of the utility model castor, by the setting of annular gasket and ball, be screwed together again, install simple and conveniently, and bracket and circular gasket are all by plastic shaping, in the time that cardan wheel uses, encounter after water, also can not get rusty, durable in use, and plastics light weight, uses lighter and handier.
