Abstract
The utility model discloses a from general purpose sleeve of taking seal ring location, the novel nipple rectifier comprises a cylindrical shel, the barrel spanner link and fastener link have, the fastener link is equipped with polygonal hole, its characterized in that is in the nozzle end in polygonal hole still be equipped with the seal ring locating hole, the aperture of seal ring locating hole and seal ring's external diameter looks adaptation, the degree of depth of seal ring locating hole slightly be less than seal ring's thickness. During the rotation of the sleeve, the sealing washer will not produce radial play, thus improving the reliability of the connection. Meanwhile, the depth of the positioning hole of the sealing washer is slightly smaller than the thickness of the sealing washer, so that the sleeve can be prevented from being scratched and abraded due to the contact with the surface of a product in the fastening process.
Description
Technical Field
The utility model belongs to the technical field of the spanner instrument and specifically relates to a general purpose sleeve from area seal ring location is related to a sleeve, specifically speaking.
Background
The connection of two workpieces by bolts or nuts is a common detachable connection mode in engineering. When connecting, usually need to add and establish the seal ring in order to strengthen the reliability and the leakproofness of fastening. The head of the bolt or nut is generally polygonal, such as a hexagonal head or a dodecagonal head, while the sealing washer is more circular. Taking the hexagon head bolt and the circular sealing washer as an example, when fastening, the hexagon head bolt and the circular sealing washer are assembled firstly, and then the hexagon head bolt is fastened by using a corresponding wrench tool. During this process, the sealing gasket can experience radial and axial play. Because the hexagon head bolt is pre-tightened, the axial movement is small and can not be considered; and radial play cannot be eliminated, and eccentricity can occur in the assembling and connecting process, so that the reliability is influenced.
Disclosure of Invention
The to-be-solved of the utility model is that the above-mentioned technical problem that prior art exists aims at providing one kind and can carry out the sleeve of accurate positioning to seal ring, prevents that seal ring from taking place off-centre when fastening the bolt, improves the assembly connection reliability.
In order to solve the above problem, the utility model adopts the following technical scheme: the universal sleeve with the sealing washer positioning function comprises a barrel body, wherein the barrel body is provided with a wrench connecting end and a fastener connecting end, the fastener connecting end is provided with a polygonal hole, and the universal sleeve is characterized in that a sealing washer positioning hole is further formed in the barrel opening end of the polygonal hole, the diameter of the sealing washer positioning hole is matched with the outer diameter of a sealing washer, and the depth of the sealing washer positioning hole is slightly smaller than the thickness of the sealing washer.
The utility model discloses a from general purpose sleeve of taking seal ring location assembles the subassembly with fastener and seal ring, and with telescopic fastener link cover on this subassembly again, the polygonal hole and the fastener of barrel form the cooperation, and the seal ring locating hole and the seal ring of barrel form the cooperation, and at the rotatory in-process of sleeve, seal ring can not produce radial drunkenness, therefore has improved the reliability of connecting. Meanwhile, the depth of the positioning hole of the sealing washer is slightly smaller than the thickness of the sealing washer, so that the sleeve can be prevented from being scratched and abraded due to the contact with the surface of a product in the fastening process.
The utility model discloses a from general purpose sleeve of taking seal ring location, simple structure, convenient operation. Aiming at the fastening of bolts and sealing gaskets with different specifications, only the corresponding specification of the sleeve needs to be replaced, and the working efficiency is greatly improved.
As the improvement of the utility model, the positioning hole of the sealing washer is a round hole.
As a further improvement of the utility model, the polygonal hole is a hexagonal hole or a dodecagonal hole.
As a further improvement of the present invention, the fastening member is a bolt or a nut.
As a still further improvement of the present invention, the wrench connecting end of the barrel is connected to a manual or electric fastening tool.
As a further improvement of the present invention, the wrench connecting end of the barrel is connected to a manual socket wrench, a motorized socket wrench or a wind gun.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the universal sleeve with a sealing gasket for positioning according to the present invention.
Fig. 2 is a top view of fig. 1.
In the figure, 1-a sealing ring positioning hole, 2-a polygonal hole, 3-a fastener connecting end, 4-a cylinder body and 5-a wrench connecting end.
Detailed Description
Referring to fig. 1 and 2, the utility model discloses a general purpose sleeve of area seal ring location certainly, includes barrel 4. In the present embodiment, the cylindrical body 4 has a cylindrical shape.
The barrel 4 has a wrench attachment end 5 and a fastener attachment end 3. The fastener connecting end 3 is provided with a polygonal hole 2 matched with the fastener, the opening end of the polygonal hole 2 is also provided with a sealing washer positioning hole 1, the aperture of the sealing washer positioning hole 1 is matched with the outer diameter of a sealing washer, and the depth of the sealing washer positioning hole 1 is slightly smaller than the thickness of the sealing washer.
The shape of the sealing washer positioning hole 1 is determined according to the shape of the sealing washer. In this embodiment, the positioning hole of the sealing gasket is a circular hole.
The shape of the polygonal hole 2 depends on the shape of the fastener, which is generally a hexagon or a dodecagon. In the present embodiment, the polygonal hole 2 is a hexagonal hole.
The fastener can be a bolt or a nut.
The wrench connecting end 5 of the barrel may be connected to any kind of manual or electric fastening tool, such as a manual socket wrench, a motorized socket wrench or a pneumatic gun.
The utility model discloses a from general purpose sleeve of taking seal ring location assembles the work piece according to following mode:
The fastener and sealing washer are assembled into an assembly with the wrench connecting end 5 of the socket connected to the wrench. Then the fastener connecting end 3 of the sleeve is sleeved on the fastener and sealing washer assembly, so that the polygonal hole 2 of the cylinder body is matched with the fastener, and the sealing washer positioning hole 1 of the cylinder body is matched with the sealing washer. The cylinder 4 is rotated, the polygonal hole 2 of the cylinder drives the fastener to rotate, and the two workpieces are assembled into a whole.
In the rotating process of the sleeve, the sealing washer is integrally limited in the sealing washer positioning hole 1, so that radial play cannot be generated, and the connection reliability is improved. Meanwhile, the depth of the positioning hole of the sealing washer is slightly smaller than the thickness of the sealing washer, so that the sleeve can be prevented from being scratched and abraded due to the contact with the surface of a product in the fastening process.
The utility model discloses a from general purpose sleeve of taking seal ring location, simple structure, convenient operation. Aiming at the fastening of bolts and sealing gaskets with different specifications, only the corresponding specification of the sleeve needs to be replaced, and the working efficiency is greatly improved.
It should be understood that: the above embodiments are merely illustrative, not restrictive, of the present invention, and any inventions not exceeding the spirit of the present invention are all within the scope of the present invention.
