Abstract

The utility model relates to a combined sleeve barrel, which is an accessory of a standard hexagonal sleeve barrel for disassembling and assembling nuts and screw bolts. The utility model is characterized in that a plurality of hexagonal sleeves are arranged in a hexagonal cavity of a basic body of the hexagonal sleeve barrel, wherein the hexagonal sleeves are sheathed successively; the sizes of cavities of the hexagonal sleeves are suitable to the sizes of head parts of the standard nuts (screw bolts), and can be selected as required at the time of use. Because only based on one basic hexagonal sleeve barrel, the space occupation can be reduced, the packaging materials can be saved, the weight of a tool box can be reduced and the cost can be reduced.

Description

A kind of modular sleeve

Affiliated technical field

The utility model relates to a kind of modular sleeve, it is the annex that is used for the standard hex sleeve that dismounting nut, bolt use, be characterized in: a Hexagonal jacket element body, in its hexagonal vestibule, also have several hexagonal covers, several hexagonal covers are to be nested successively, the vestibule size of hexagonal cover is fit to the head dimensions of standard nut (bolt), in use, can select for use as required, owing to only based on basic Hexagonal jacket of use, thereby reduced the space of taking up an area of, saved packaging material, reduce the weight in tool box, reduced cost.

Background technology

Hexagonal jacket is used for dismounting nut (bolt) and uses very general, when the nut that needs dismounting (bolt) specification more, or the nut (bolt) that needs dismounting is when having multiple occasion, standby sleeve is just a lot, sometimes complete sleeve comes to this in the tool box that we see, sleeve is many, and the volume of packing box increases, weight increases, and the cost of product also increases.

The purpose of utility model

The utility model adopts a kind of modular sleeve, and this modular sleeve characteristics are: structure is extremely simple, is fit to produce in large quantity, and low cost of manufacture can be saved packaging material, reduces the weight in tool box, reduces cost, and uses also very convenient.

Technical scheme

The technical scheme that its technical problem that solves the utility model adopts is: by a Hexagonal jacket, several hexagonal covers, it is characterized in that: several hexagonal covers are to be nested successively, 2/3 place of the seamed edge of the two adjacent surfaces handing-over of hexagonal cover is an open slot, trench bottom is a bottom land hole, its effect is to avoid the hexagonal cover tightly to block nut (bolt) and be convenient to taking-up, has a pull hook hole at least on the side of hexagonal cover, its effect is to be convenient to the hexagonal cover is taken out from Hexagonal jacket, and the material of hexagonal cover is after heat treatment to have elasticity, and the alloy steel material that certain degree of hardness is arranged.

Beneficial effect

Owing to, thereby reduced the space of taking up an area of only based on basic Hexagonal jacket of use, saved packaging material, reduced the weight in tool box, reduced cost.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is a Hexagonal jacket element body three-dimensional view,

Fig. 2 is tenon position, a Hexagonal jacket element body side three-dimensional view,

Fig. 3 is a hexagonal cylindrical shell three-dimensional view,

Fig. 2 is Hexagonal jacket and the hexagonal cylindrical shell combination schematic diagram that is nested successively.

Among Fig. 1,1. Hexagonal jacket,

Among Fig. 3,2. hexagonal is overlapped 3. bottom land holes, 4. open slot, 5. pull hook hole.

The utility model is to implement like this:

A kind of modular sleeve, be by a Hexagonal jacket (1), several hexagonal covers (2) are formed, it is characterized in that: several hexagonal covers (2) are to be nested successively, 2/3 place of the seamed edge of the two adjacent surfaces handing-over of hexagonal cover (2) is an open slot (4), trench bottom is a bottom land hole (3), its effect is to avoid hexagonal cover (2) tightly to block nut (bolt) and be convenient to take out, has a pull hook hole (5) on the face of hexagonal cover (2) at least, its effect is to be convenient to hexagonal cover (2) is taken out from Hexagonal jacket (1), and the material of hexagonal cover (2) is after heat treatment to have elasticity, and the alloy steel material that certain degree of hardness is arranged.

Claims

1. a modular sleeve is by a Hexagonal jacket (1), and several hexagonal covers (2) are formed, and it is characterized in that: several hexagonal covers (2) are to be nested successively.

2. a kind of modular sleeve according to claim 1 is characterized in that: 2/3 place of the seamed edge of the two adjacent surfaces handing-over of hexagonal cover (2) is an open slot (4), and trench bottom is a bottom land hole (3).
