Description

Multifunctional sleeve for narrow space
Technical Field
The utility model relates to a multifunctional sleeve for narrow and small space belongs to mechanical wrench technical field.
Background
When the bolt and the nut in the counter bore or the groove are disassembled and assembled, only the ratchet wheel sleeve can be used, and when the ratchet wheel and the sleeve are combined for use, certain requirements are met on the use space of the bolt or the nut in the axial direction. When the bolts and nuts in the counter bores or the grooves on the machine parts are disassembled, sometimes the ratchet sleeve can not be used due to limited space, and at the moment, the bolts and the nuts on the parts can be disassembled only after the parts are disassembled from the machine, which wastes time and labor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome among the prior art when bolt, the nut in counter bore or the recess on dismouting machine part, can be because the space is limited sometimes and can't use the telescopic not enough of ratchet, provide a multi-functional sleeve that is used for narrow and small space.
A multi-function sleeve for small spaces, comprising:
the sleeve comprises a sleeve head, a sleeve body and a sleeve body, wherein one end of the sleeve head is provided with a groove, and the other end of the sleeve head is provided with a quincunx inner hole;
the side part of one end of the connecting rod is provided with a pin shaft hole;
the connecting rod is movably connected with the groove through a pin shaft.
Furthermore, the end part of the other end of the connecting rod is provided with a square inner hole used for being matched with the ratchet wheel.
Further, the sleeve head is in the shape of a regular hexagon.
Further, the angle between adjacent patterns of the quincunx inner hole is 30 degrees.
Further, the thickness of the connecting rod is the same as the depth of the groove.
Furthermore, the end part of the connecting rod, which is provided with the pin shaft hole, is in a circular arc shape.
Compared with the prior art, the utility model discloses the beneficial effect who reaches: the utility model discloses the whole height dimension of this sleeve reduces, and is less to bolt, the ascending usage space requirement of nut axial direction, can satisfy bolt, the nut at narrow and small space dismouting counter bore or inslot, both can use with the open-end wrench cooperation, also can insert the member in the connecting rod hole and carry out the dismouting.
Drawings
Fig. 1 is an exploded view of the sleeve structure of the present invention;
FIG. 2 is a schematic view of the shape of the sleeve head of the present invention;
fig. 3 is a top view of the sleeve head of the present invention;
FIG. 4 shows the sleeve head of the present invention in a state of being engaged with the ratchet;

In the figure: 1. a pin shaft; 2. a sleeve head; 3. a connecting rod; 4. a square inner hole; 5. a pin shaft hole; 6. a pin shaft hole; 7. a quincunx inner hole; 8. and (4) a groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Fig. 1-5 show a multifunctional sleeve for narrow space, which is composed of a pin shaft 1, a sleeve head 2 and a connecting rod 3;
one end of the sleeve head 2 is provided with a groove 8, and the other end is provided with a quincunx inner hole 7; the angle between adjacent patterns of the quincunx inner hole 7 is 30 degrees, the minimum rotation angle is 30 degrees when the nut or the bolt is clamped, and the use is more convenient. A pin shaft hole 5 is formed in the side part of one end of the connecting rod 3; the groove 8 is provided with a fixing hole 6 matched with the pin shaft hole 5, and the connecting rod 3 is movably connected with the groove 8 through a pin shaft 1; the connecting rod 3 can rotate around the pin 1 relative to the sleeve head 2.
In the embodiment, the end of the other end of the connecting rod 3 is provided with a square inner hole 4 used for matching with a ratchet wheel; as shown in FIG. 4, the sleeve is matched with the ratchet wheel to complete the assembly and disassembly of the bolt and the nut.
As shown in fig. 2, the sleeve head 2 is regular hexagon, and can be used with an open-end wrench, so that the universality of the sleeve head 2 is improved, and the application range is enlarged.
As shown in fig. 5, the thickness of the connecting rod 3 is the same as the depth of the groove 8, and when the connecting rod 3 is used in a narrow environment, the height is limited to avoid a lateral state.
As shown in fig. 1, the end of the connecting rod 3, which is provided with the pin shaft hole 5, is arc-shaped; the arc shape is convenient for the connecting rod 3 to rotate and rub the bottom of the groove 8.
The utility model discloses the whole height dimension of this sleeve reduces, and is less to bolt, the ascending usage space requirement of nut axial direction, can satisfy bolt, the nut at narrow and small space dismouting counter bore or inslot, both can use with the open-end wrench cooperation, also can insert the member in the connecting rod hole and carry out the dismouting.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
