Description

The mute castor of climbing stairs

Technical field

The utility model is related to luggage technical field more particularly to the mute castors of climbing stairs.

Background technology

Luggage case is also known as suitcase, trolley case, is entrained to place the chest of article when going out, it is its of luggage In a type, usual luggage case be for placing required clothing, personal-care supplies and souvenir on journey, early stage Luggage case is made of with timber or other heavy materials, and with popularizing for air travel, the material of luggage case tends to more light Hard plastic or cloth, most model can facilitate pulling, while castor is also luggage case also with built-in steamboat with pull rod One of important component.

However the castor of existing luggage case is in use there is some shortcomings, in castor speeling stairway The phenomenon that easily skidding, while castor moving process can generate larger noise, affect the overall utility of luggage case.

Utility model content

The purpose of this utility model is to solve shortcoming in the prior art, and the climbing stairs proposed is mute Castor.

To achieve these goals, the utility model employs following technical solution：The mute castor of climbing stairs, including Castor is provided with second bearing at the castor centre of surface, and second bearing passes through clip-connecting rod and is rotatablely connected with support plate, institute It states support plate upper surface and is provided with clutch shaft bearing, and clutch shaft bearing inner rotation is connected with positioning column, the positioning outer surface of column Corner is provided with seal closure, oil filler point is offered inside the seal closure, and oil filler point inner surface wall both sides are provided with counterflow-preventing Plate, the castor is socketed with mute ring, bayonet slot ring and dirt-proof boot successively from inside to outside, and card slot ring surface offers card slot, institute It states castor both sides appearance wall and is provided with anti-dropping gasket.

As further describing for above-mentioned technical proposal：

The cross section of the seal closure is arc smooth structure.

As further describing for above-mentioned technical proposal：

The clutch shaft bearing and the internal-and external diameter of second bearing are equal in magnitude.

As further describing for above-mentioned technical proposal：

The card slot is equipped with multiple altogether, and spacing is equal in magnitude between any two for multiple card slots, the cross section of the card slot For trapezium structure, outside diameter is more than inside diameter 5mm.

As further describing for above-mentioned technical proposal：

The outside diameter of the oil filler point is more than inside diameter 6mm.

As further describing for above-mentioned technical proposal：

There are two the anti-dropping gasket is installed altogether, and two anti-dropping gaskets are symmetrical about the vertical center line of castor.

It, can be in castor speeling stairway first by the card slot of setting in the utility model so that card slot is embedded in upper strata At the edge-corner of ladder, so as to increase the relative friction forces of castor and ladder, prevent castor from occurring to beat in speeling stairway The phenomenon that sliding, the stability in use of castor is enhanced, it, can be right in castor speeling stairway secondly by the mute ring of setting The vibrating noise that castor and step lands generate plays effective buffering effect, maximumlly reduces castor in speeling stairway When the noise effect that generates, finally by the oil filler point of setting, can regularly be noted to the junction of clutch shaft bearing and positioning column Enter lubricating oil, so as to play the effect of lubrication to positioning column and clutch shaft bearing, while the structure of anti-reverse flowing plate also avoids lubricating Fry dried food ingredients gives birth to the phenomenon that counterflow leak, improves the safety and stability of castor operation.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.

With reference to Fig. 1-4, including castor 6, second bearing is provided at 6 centre of surface of castor for the mute castor of climbing stairs 10, and second bearing 10 is rotatablely connected by clip-connecting rod 5 and support plate 2,2 upper surface of support plate is provided with clutch shaft bearing 4, and One bearing, 4 inner rotation is connected with positioning column 3, and 3 outer surface corner of positioning column is provided with seal closure 1, is opened up inside seal closure 1 There is oil filler point 13, and 13 inner surface wall both sides of oil filler point are provided with anti-reverse flowing plate 12, castor 6 is socketed with mute ring successively from inside to outside 9th, bayonet slot ring 8 and dirt-proof boot 7, and 8 surface of bayonet slot ring offers card slot 11,6 both sides appearance wall of castor is provided with anti-dropping gasket 14.

The cross section of seal closure 1 is arc smooth structure, and the internal-and external diameter of clutch shaft bearing 4 and second bearing 10 is equal in magnitude, Card slot 11 is equipped with multiple altogether, and spacing is equal in magnitude between any two for multiple card slots 11, and the cross section of card slot 11 is trapezium structure, Its outside diameter is more than inside diameter 5mm, and the outside diameter of oil filler point 13 is more than inside diameter 6mm, and anti-dropping gasket 14 is installed altogether There are two, and two anti-dropping gaskets 14 are symmetrical about the vertical center line of castor 6.

Mute 9 inside of ring is made of rubber material, on the one hand can play the role of bumper and absorbing shock to castor 6, another Aspect also plays assimilation effect to vibrating noise, and the moving process of castor 6 is avoided to send out larger noise.

Operation principle：In use, support plate 2 is embedded into the installation site of luggage bottom by positioning column 3, by anticreep pad 14 sets of piece is connected to progress anticreep on clip-connecting rod 5 and fixes, when 6 speeling stairway of castor, castor 6 and the edge first with upper strata ladder Place's contact, dirt-proof boot 7 is extruded in embedded card slot 11 at this time, so as to which the edge of upper strata ladder is pressed into card slot 11, to foot Wheel 6 is fixed, and user of service pulls luggage later, so that the function of the realization speeling stairway of castor 6, and 9 energy of mute ring Enough reducing the vibrating noise that 6 moving process of castor generates influences so that 6 entire run of castor.

The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
