Abstract
The utility model discloses an improved structure of a socket wrench adapter rod, and aims to provide a socket wrench adapter rod which is flexible and convenient to use and combine and can effectively reduce the types and specifications of matched components of a socket wrench. The connecting device comprises a cylindrical rod body for connecting a male adapter and a female adapter, wherein the male adapter (5) is a square tenon, and the maximum diameter of the square tenon is smaller than or equal to the diameter of the rod body (4); the female adapter (2) is composed of a square tenon hole (3) matched with the square tenon and a cylindrical counter bore (1) which is positioned above the square tenon hole, communicated with the square tenon hole and matched with the diameter of the rod body (4), and a through hole (9) penetrates through the outer surface of the female adapter (2) corresponding to the counter bore (1). The socket wrench adapter rod is simple in structure and convenient to manufacture, store and manage, and is an improved structure of the socket wrench adapter rod.
Description
Technical Field
The utility model relates to an improved structure matched with a socket wrench, in particular to an improved structure of a socket wrench adapter rod, belonging to hardware tools.
Background
Socket spanner has hexagonal hole or dodecagonal hole, the other end has many specifications sleeve head of square tenon hole by one end, through square tenon and the adapter of this sleeve head looks adaptation, many keysets, the L type handle of different length, with the complete sets that multiple supporting subassemblies such as the straight-bar handle of adapter looks adaptation constitute. The defects of complex matching accessories, troublesome production, manufacture, combination and storage management and the like mainly exist; improvements are needed.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide an improved structure of a socket wrench adapter rod, which is flexible and convenient to use and combine and can effectively reduce the types and specifications of matched components of a socket wrench.
In order to achieve the purpose, the utility model adopts the following technical scheme: the square tenon type connecting device comprises a cylindrical rod body for connecting a male adapter and a female adapter, wherein the male adapter is a square tenon, and the maximum diameter of the square tenon is smaller than or equal to the diameter of the rod body; the female adapter is composed of a square tenon hole matched with the square tenon and a cylindrical counter bore which is positioned above the square tenon hole, communicated with the square tenon hole and matched with the diameter of the rod body, and a through hole is formed in the outer surface of the female adapter corresponding to the counter bore.
The switching male joint is provided with a spring contact ball, and the hole walls on four sides of the square mortise are provided with positioning holes matched with the first spring contact ball.
The rod body is provided with a second spring collision bead.
Compared with the prior art, the improved technical scheme is adopted on the basis of the traditional adapter rod, so that the utility model has the following advantages:
1) the cylindrical counter bore is added above the square tenon hole, and when a plurality of adapter rods are connected and combined to form combined rod pieces with different lengths, the rigidity of the combined rod pieces can be enhanced, so that the adapter rods with different lengths can be completely replaced by a plurality of adapter rods with the same length, and the combined rod piece is convenient to process, manufacture and store and manage;
2) the plurality of adapter rods can be connected and combined as required to form straight rods with different lengths, so that a handle of the straight rod can be omitted, and the function of a stress application rod can be achieved, so that the function of matched accessories is reduced;
3) the through hole is added on the adapter rod, and the straight rod handle can be directly utilized to screw the adapter rod, so that matched components such as a square tenon adapter and an L-shaped handle can be completely eliminated.
In conclusion, the socket wrench has the advantages of simple structure, flexible and convenient use and combination, and can effectively reduce the number of the types and specifications of the matched components of the socket wrench.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a left side view of FIG. 1;
FIG. 3 is a cross-sectional view A-A of FIG. 1;
FIG. 4 is a schematic diagram of a structure in which a plurality of the present invention are used in combination.
In the figure: counter bore 1, switching female joint 2, square tenon hole 3, the body of rod 4, switching male joint 5, first spring touch pearl 6, second spring touch pearl 7, locating hole 8, through-hole 9.
Detailed Description
The utility model is further described with reference to the following figures and specific examples.
As shown in FIGS. 1 to 3: the lower end of the cylindrical rod body 4 is provided with an adapter male joint 5 which is connected with the cylindrical rod body into a whole, and the upper end of the cylindrical rod body 4 is provided with an adapter female joint 2 which is connected with the cylindrical rod body into a whole. The adapter male joint 5 is a square tenon, and the maximum diameter of the square tenon is smaller than or equal to the diameter of the rod body 4; the adapting female joint 2 consists of a square tenon hole 3 matched with the square tenon head and a cylindrical counter bore 1 which is positioned above the square tenon hole, communicated with the square tenon hole and matched with the diameter of the rod body 4. And a through hole 9 is formed on the outer surface of the adapter female head 2 corresponding to the position of the counter bore 1.
In order to prevent the adapter male head 5 from sliding out of the square tenon hole 3, a spring collision bead 6 is arranged on one surface of the adapter male head 5; correspondingly, positioning holes 8 matched with the first spring contact balls 6 are formed in the wall of each of the four sides of the square tenon hole 3.
In order to avoid the force application rod formed by combining a plurality of switching rods from sliding out of the through hole 9, a second spring collision bead 7 is arranged on each rod body 4.
As shown in fig. 4: when the sleeve head is used, the adapter male head 5 of one adapter rod is directly inserted into a square mortise of the sleeve head (not shown in the figure), and the stress application rod (which is formed by combining two adapter rods in the embodiment and is a two-dot chain line part in fig. 4) is inserted into the through hole 9 of the adapter rod (a solid line part in fig. 4) connected with the sleeve head, so that the sleeve head can be screwed.
