Description
Technical Field
The utility model belongs to the technical field of optical instrument, concretely relates to coupling device of optical rod.
Background
The optical rods are the most commonly used instruments in optical scientific research and experiments, at present, the end surfaces of the optical rods are generally provided with threaded holes, and the optical rods are connected with each other by matching the threaded holes on the end surfaces with external studs. The connection mode is simplest and most common, and the used external stud generally has two modes, one mode is a fixed thread type, the other mode is a large thread type at one end, and the other mode is a small thread type at the other end, because the two ends of the optical rod are threaded holes with different types. The type of threaded hole on the end face of the connection between two optical rods determines that a corresponding stud must be used, for example, if the connection between two optical rods is made, a second stud must be used if the type of threaded hole is different. In an optical experiment, if a plurality of optical rods are simultaneously connected into one optical rod, sometimes two kinds of studs are required to be simultaneously arranged, if only one kind of studs is arranged, sometimes the connection cannot be completed, sometimes a proper stud cannot be found in half a day, and in some cases, the efficiency of the optical experiment is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome current optical rod coupling device's shortcoming, provide a coupling device of optical rod reasonable in design, simple structure, work efficiency are high.
The technical scheme for solving the technical problems is as follows: the one end of swivel nut can be dismantled and be connected with first screw rod, the other end can be dismantled and be connected with the second screw rod, and the structure of first screw rod is greater than other end diameter for one end diameter, and the biggest external diameter of first screw rod is less than the external diameter of swivel nut, all processes threadedly on the lateral wall of first screw rod and the swivel nut lateral wall, and the second screw rod is the same with first screw rod structure.
As a preferred technical scheme, the thread insert structure is formed by sequentially processing a first through hole a, a second through hole b, a third through hole c, a fourth through hole d and a fifth through hole e which are communicated with each other along a central line from one end face to the other end, wherein the first through hole a is equal to the fifth through hole e, the second through hole b is equal to the fourth through hole d, threads are processed on the inner wall of the first through hole a, the diameter of the first through hole a is larger than that of the third through hole c, the diameter of the third through hole c is larger than that of the second through hole b, threads are processed on the inner wall of the second through hole b, the outer diameter of the large end of the first screw is matched with that of the first through hole a, and the outer diameter of the small end of the first screw is matched with that of.
As a preferable technical scheme, the length of the large end of the first screw is equal to that of the first through hole a, and the sum of the length of the small end of the second screw and the length of the small end of the first screw is less than or equal to that of the third through hole c of the threaded sleeve.
The utility model discloses a one end of swivel nut can be dismantled and be connected with first screw rod, the other end can be dismantled and be connected with the second screw rod, can realize two hookups that have the optical rod of same specification screw or different specification screws, has easy operation, practicality strong, improves work efficiency's advantage.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, but the present invention is not limited to the following embodiments.
In fig. 1, a coupling device of an optical rod of the present embodiment is formed by connecting a first screw 1, a threaded sleeve 2, and a second screw 3.
A first through hole a, a second through hole b, a third through hole c, a fourth through hole d and a fifth through hole e which are communicated with each other are sequentially processed from one end surface to the other end of the screw sleeve 2 along a central line, the first through hole a is equal to the fifth through hole e, the second through hole b is equal to the fourth through hole d, threads are processed on the inner walls of the first through hole a and the second through hole b, the diameter of the first through hole a is larger than that of the third through hole c, the diameter of the third through hole c is larger than that of the second through hole b, one end of the screw sleeve 2 is in threaded connection with a first screw rod 1, the outer diameter of one end of the first screw rod 1 is larger than that of the other end, a linear groove is processed on the end surface of the large end, the outer diameter of the large end of the first screw rod 1 is matched with the first through hole a, the outer diameter of the small end is matched with the second through hole b, the length of the large end of the first screw rod 1 is equal to that, the structure of the second screw rod 3 is the same as that of the first screw rod 1, the outer diameter of the large end of the second screw rod 3 is matched with the fifth through hole e, the outer diameter of the small end of the second screw rod 3 is matched with the fourth through hole d, and the sum of the length of the small end of the first screw rod 1 and the length of the small end of the second screw rod 3 is equal to the length of the third through hole c of the screw sleeve 2.
When the two optical rods need to be connected, when the specifications of threaded holes on the end surfaces of the two optical rods are matched with the external threads of the threaded sleeve 2, the first screw 1 and the second screw 3 are screwed into the threaded sleeve 2, and the two optical rods are connected through the threaded sleeve 2; when the screw hole specification of an optical rod terminal surface and the external screw thread phase-match of swivel nut 2, the screw hole specification of another optical rod terminal surface and the external screw thread of first screw rod 1 or 3 main aspects of second screw rod match, then an optical rod links to each other with swivel nut 2, and another optical rod links to each other with first screw rod 1 or second screw rod 3, consequently the utility model discloses can realize two hookups of optical rod that have same specification screw or different specification screws, have easy operation, the practicality is strong, improve work efficiency's advantage.
