Description
Technical field
The utility model belongs to round nut assembly field, relates in particular to a kind of round nut spanner.
Background technique
Ordinary circumstance, round nut can be assembled and disassembled very easily using hook-headed wrench.But in vehicle bridge, round nut installation position
It is more special to set, and can't completely be exposed to outside, and is mounted in some inside parts, in this case, round nut
Peripheral space is limited, and hook-headed wrench is not just available, so need to make special spanner, to solve round nut in this case
Assembly and disassembly problem.
Utility model content
For various deficiencies of the prior art, it is proposed that it is a kind of can in a limited space in dismounting round nut spanner.
To achieve the above object, the utility model provides the following technical solutions:
A kind of round nut spanner, is used cooperatively with round nut, and multiple grooves are arranged in the outer rim of the round nut, described
Round nut spanner includes sleeve and connector and handle in integral structure, and the sleeve is in hollow cylindrical shape, horizontal
Section is rounded, and multiple protrusions to fasten with the groove, one end of the connector and handle is arranged in the sleeve lining
It is connected, the other end and the sleeve are connected.
Further, the quantity of the protrusion is less equal than the quantity of groove.
Further, the protrusion is distributed in the inner surface of the sleeve.
Further, the cross section of the protrusion is in rectangle.
Further, the U-shaped profile of the connector.
Further, notch of the upper end setting of the sleeve to observe protrusion.
Further, the longitudinal section of the handle is rounded, and annular knurl is arranged to increase friction in surface.
The beneficial effects of the utility model are:
1, the diameter of sleeve can be arranged according to the diameter of round nut to be assembled and disassembled, and the diameter and length of handle also can be according to need
It designs, plasticity is strong；
2, manual operations is only needed, and easy to operate, quick, the limitation used without equipment.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of embodiment of the utility model；
Fig. 2 is the overall structure diagram of the utility model another embodiment；
Fig. 3 is the overall structure diagram of the utility model another embodiment；
In attached drawing: 1- sleeve, 2- connector, 3- handle, 4- protrusion, 5- notch.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
Logical technical staff other similar embodiments obtained without making creative work, all should belong to the application
The range of protection.In addition, the direction word mentioned in following embodiment, such as "upper" "lower" " left side " " right side " etc. are only with reference to attached drawing
Direction, therefore, the direction word used is for illustrative and not limiting the invention.
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
A kind of round nut spanner, is used cooperatively with round nut, and multiple grooves are arranged in the outer rim of the round nut, described
Round nut spanner includes sleeve 1 and connector 2 and handle 3 in integral structure, and the sleeve 1 is in hollow cylindrical shape,
The multiple protrusions 4 to fasten with the groove of the inner wall even distribution of the sleeve 1, raised 4 quantity is less equal than described
The quantity of groove.Raised 4 cross section is in rectangle；The U-shaped profile of the connector 2, one end and the handle 3
It is fixedly connected, the other end is fixedly connected with the sleeve 1, and U is arranged on the barrel of the side of the sleeve 1 far from connector 2
V notch v 5, to observe engaging situation of the protrusion 4 with groove；The longitudinal section of the handle 3 is rounded, the surface of the handle 3
Annular knurl is set, to increase the friction on its surface.The diameter of the sleeve 1 can be set according to the diameter of the round nut of required disassembly
Meter, the diameter and length of handle 3 can design as required, and adaptable, it is suitable for hand assembleds, efficiently solve use
Pneumatic impact spanner bring is inconvenient.
Embodiment one:
As shown in Figure 1, raised 4 setting 2, and 2 protrusions 4 are located at the both ends of the same diameter of the sleeve 1, are pacifying
When dress or disassembly round nut, by 2 protrusions 4 along the groove, slowly sleeve 1 is extended between round nut and surrounding components
Gap bottom, protrusion 4 and the engaging situation of the groove from notch 5, and guarantee protrusion 4 and after groove fastens, hold
Handle 3, rotates clockwise or counterclockwise handle, until tightening or unscrewing round nut.
As shown in Fig. 2, raised 4 setting 3, when installing or removing round nut, by 3 protrusions 4 along described recessed
Sleeve 1 is slowly extended to the gap bottom of round nut and surrounding components by slot, protrusion 4 and the groove from notch 5
Engage situation, and after guaranteeing that protrusion 4 fastens with groove, holds handle 3, rotate clockwise or counterclockwise handle 3, until will justify
Nut is tightened or is unscrewed.
Embodiment three:
As shown in figure 3, raised 4 setting 4, when installing or removing round nut, by 4 protrusions 4 along described recessed
Sleeve 1 is slowly extended to the gap bottom of round nut and surrounding components by slot, protrusion 4 and the groove from notch 5
Engage situation, and after guaranteeing that protrusion 4 fastens with groove, holds handle 3, rotate clockwise or counterclockwise handle, until will justify
Nut is tightened or is unscrewed.
The utility model is described in detail above, it is described above, only the preferred embodiment of the utility model and
, when the utility model practical range cannot be limited, i.e., all according to the made equivalent changes and modifications of the application range, it should still belong to this
In utility model covering scope.
