Abstract

The utility model relates to a sleeve cylinder for preventing rocking characterized in that one end of the sleeve cylinder is arranged with a sleeve hole used for sheathing screwing elements. A plurality of pins are circularly arranged on the peripheral surface of the sleeve cylinder in proper intervals and the outer end of each pin is exposed from the peripheral surface of the sleeve cylinder. The utility model has the advantages of uneasy rock, convenient use and high working efficiency.

Description

The sleeve that Bi Mian Roll is moving

Technical field

The utility model relates to a kind of annex of hand tools, mainly refers to the sleeve that a kind of Bi Mian Roll is moving, and when this sleeve kept flat, it can't produce rolling.

Background technology

As everyone knows, sleeve is a kind of instrument that turns nut and bolt, and the specification difference of sleeve and nut and the bolt that turns vary in size.The profile of traditional sleeve barrel tool is cylindric.Fig. 1 is traditional sleeve stereogram, and Fig. 1 has shown that two kinds of sleeves 10,12, the first kind of sleeve have a bigger diameter end 14 and a miner diameter end 16; Second kind of sleeve then is single outside diameter.No matter any sleeve, its profile all are cylindric, therefore, when sleeve was lain against ground, sleeve rolled easily on the ground.And can roll because of ground inclination or operating personnel kick.It is quite far away that sleeve rolls and to roll often, is rolled to the below of concealing close corner or board often and is not easy to obtain, and especially in large-scale workplace, for example repaiies the Trucks field, sleeve usually roll especially See trace not, cause the inconvenience in the use.

Summary of the invention

The purpose of this utility model is to provide a kind of Bi Mian Roll moving sleeve, when this sleeve lies against ground, can't produce rolling.

The purpose of this utility model is achieved through the following technical solutions: a kind of sleeve of rolling avoided, and it is characterized in that: described sleeve is established a trepanning in an end, for the socket spiro connecting element; It is to be located on the The sleeve side face with the appropriate intervals ring that a plurality of pins are arranged; The outer end system of described pin exposes to described sleeve side face.

The utility model compared with the prior art have should not roll, the advantage of easy to use, high efficiency.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is traditional sleeve stereogram.

Fig. 2 is the exploded stereogram of one of the utility model embodiment.

Fig. 3 is the state diagram that the utility model is flat on ground.

Fig. 4 is two the stereogram of the utility model embodiment.

Fig. 5 is three the stereogram of the utility model embodiment.

Fig. 6 is four the exploded stereogram of the utility model embodiment.

The specific embodiment

At first see also Fig. 2, the sleeve 20 that the utility model embodiment is provided, present embodiment are the sleeve with a bigger diameter end 22 and a miner diameter end 24.

This sleeve is to establish hexagonal or interior bihexagonal trepanning 26 (referring to Fig. 3) in one in bigger diameter end; And miner diameter end Nei The establishes one and drives hole 28, interts for spanner.

The pin 30 of predetermined number can be three, four, five, the six roots of sensation or more quantity.These pin systems are inserted in respectively in the set multiple holes of sleeve side face 29 with an end, and expose to sleeve.Whether these pins are main is to be provided with along same circumference, only be with Round week arranging also inessential.Again, these pins can be uniformly-spaced and are provided with, but also unequal interval plugs.Focus on: the outer end line system of two adjacent pin exceeds the arc surface of sleeve.

During use, as shown in Figure 3, because the line of two adjacent pin system exceeds the side face of sleeve, therefore, when the Will sleeve lay against on the plane, two adjacent pin systems formed two standpoint, sleeve is stood in the plane, and the side face of sleeve can't be contacted with ground, so sleeve can not rolled.

Fig. 4 is another preferred embodiment of the present utility model, and the sleeve 40 of present embodiment is a single outside diameter, is inserted with most pins 45 in side face.

When this sleeve keeps flat, be, stand, it can not rolled by two adjacent pins as shown in the sleeve of Fig. 3.

Fig. 5 is another preferred embodiment of the present utility model, and wherein, this sleeve 50 1 ends system establishes a trepanning 52, and the other end then is the drive end 54 of a hexagon, for the spanner socket; Duo Number Pins 55 is located on this sleeve side face.

Fig. 6 is another preferred embodiment of the present utility model, and this sleeve 60 is to have the sleeve of large and small footpath end, only also to can be the sleeve of single outside diameter.

Most pins 65 are inserted in the hole 62 of sleeve side face, can be uniformly-spaced or unequal interval arrange.Respectively this to sell in present embodiment be L shaped, be plugged on the sleeve with short end, be exposed at outside the sleeve and long end is outer.Same, the line system of the outer ends of adjacent two pins is higher than the sleeve side face, therefore, when sleeve is kept flat, is to lean against on the ground and can not roll with two Ge pin.

On the plane that the utility model system is positioned to be put when sleeve is kept flat, have the advantage that to roll, therefore sleeve roller can not take place then the disappearance that is difficult to look for, be convenient to the user and take.

What must illustrate in addition is that technology characteristic of the present utility model lies in the pin that the sleeve side face is provided with proper number, forms anchor point by pin, gets final product to prevent the sleeve progressive rolling movement.

Claims

1, a kind of sleeve of rolling avoided, it is characterized in that: described sleeve is established a trepanning in an end, for the socket spiro connecting element; It is to be located on this sleeve side face with the appropriate intervals ring that a plurality of pins are arranged; The outer end system of described pin exposes to described sleeve side face.

2, sleeve according to claim 1 is characterized in that: the outer end line system of described two adjacent pin is higher than the side face of described sleeve.
