Detailed Description
In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The invention is further elucidated with reference to the drawings and the embodiments.
In the description of the present application, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present application.
The application relates to a special screw wrench for fastening spread spectrum module waveguide connection, which comprises a torque support rod, a fixed handle and an inner hexagonal screw member; one end of the moment support rod is inserted into the fixed handle; the two ends of the inner hexagonal screw piece are in inner hexagonal shapes with different outer diameters; the inner hexagonal screw piece penetrates through the other end of the moment support rod, and the middle part of the inner hexagonal screw piece is fixed on the moment support rod; the inner hexagonal screw piece is integrally or detachably connected with the end part of the moment support rod; the inner hexagonal screw piece and the moment support rod form a T shape.
The hex socket screw member is ninety degrees from the torque support rod, just the ninety degree angle allows the wrench to extend into the limited space of the straight waveguide and product space.
The outer diameters of the two ends of the socket head cap screw are different, so that the socket head cap screw can be suitable for different screws commonly used in high-frequency straight waveguide connection.
In addition, considering that the position of a screw in the high-frequency straight waveguide connection is possibly deeper, the length of the current fixed handle and the moment supporting rod is not always suitable, so the structure of the fixed handle is improved, and the whole device has certain flexibility.
As a specific example, the end of the moment support bar is fixed in the third handle part; the outer side of the rear end of the first handle part is provided with threads protruding out of the side wall of the first handle part and used for being in threaded connection with the inner diameter of the second handle part; and the outer side of the rear end of the second handle part is provided with threads protruding out of the side wall of the second handle part and used for being in threaded connection with the inner diameter of the third handle part.
And the inner diameters of the second handle part and the third handle part are all fully distributed with threads a.
This corresponds to screwing three handle portions one after the other, with the thread distance between each other being used to adjust the length of the entire wrench. Moreover, the moving direction of the whole wrench is perpendicular to the advancing and retreating direction of the threads between the handle parts, so that the movable structure between the handle parts has no influence on the use of the wrench in the use process.
As another specific example, the outer diameter of the rear end of the moment support rod is provided with threads which are in threaded connection with a nut in the second handle part.
The first handle part and the second handle part and the third handle part are connected by adopting a sliding ring structure, so that the first handle part, the second handle part and the third handle part rotate on a radial surface, namely, the first handle part, the second handle part and the third handle part can rotate in sequence in a radial direction, but the axial direction does not generate displacement.
Specifically, the slip rings include a convex groove and a convex snap ring, and are present in pairs; the convex groove and the convex clamping ring are respectively positioned on one surface opposite to one group of adjacent handle parts;
the inner diameter of the second handle part is slightly smaller than the inner diameters of the first handle part and the third handle part. The second handle part is in threaded connection with the moment support rod.
When the screw is used, the hexagon socket screw piece is fixed on the screw, and then the length of the handle part is adjusted as required, and only the second handle part needs to be screwed.
The external diameter of hexagon socket screw spare is generally fixed, and the spanner of itself is with low costs moreover, can direct integration processing, but for convenient, also can adopt removable structure.
As a specific structure, the socket head cap screw member includes two socket head cap screws having different outer diameters; each inner hexagonal screw is a six-sided straight cylinder, and a concave shape is arranged in the center of one end of each inner hexagonal screw; the concave side wall is provided with a group of polygonal through holes and is provided with a penetration column; the ends of the two socket head cap screws with the concave shapes are opposite, and one socket head cap screw with the smaller outer diameter is placed in the socket head cap screw with the larger outer diameter; the penetrating and inserting column is matched with the polygonal through hole; the inserting column penetrates through the center of the end part of the free end of the torque supporting rod, penetrates through the through holes in the two hexagon socket head cap screws and is inserted into the torque supporting rod; the moment support rod is made of metal; the penetrating and inserting column is made of a strong magnet material.
When the inner hexagonal screw piece is selected, the inner hexagonal screw with the smaller outer diameter is positioned in the concave shape of the inner hexagonal screw with the larger outer diameter, and then the whole inner hexagonal screw piece is placed in the through hole at the end part of the torque support rod. The penetration column penetrates through the centers of the end parts of the free ends of the torque support rods in sequence, penetrates through the through holes in the two hexagon socket head cap screws, is inserted into the torque support rods, and is tightly attracted by virtue of the characteristic of strong magnets. At the moment, the free end of the inserting column is still positioned outside the free end of the torque supporting rod, so that the inner hexagonal screw piece can be pulled out and replaced conveniently. The scheme is only to aim at the complicated installation environment of the inner diameter of the screw, the types of the inner hexagonal inner diameter types required by general conditions are not many, the requirements of full types can be met by selecting a plurality of wrenches, and the replaceable scheme in the embodiment can also be adopted.
Although the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the details of the foregoing embodiments, and various equivalent changes (such as number, shape, position, etc.) may be made to the technical solution of the present invention within the technical spirit of the present invention, and the equivalents are protected by the present invention.
