The utility model provides a pair of shadowless lamp balance arm connection structure, simple structure, two kinds of effects of a screw have not only solved the not enough cost of also having practiced thrift simultaneously of design before, have brought very big facility for installation and later stage debugging.
Description
Technical Field
The utility model relates to the field of medical equipment, in particular to shadowless lamp balance arm connection structure.
Background
The connecting part of a T-shaped shaft 2 and an upper pipe of an existing shadowless lamp balance arm is shown in figure 1, in the structure, the upper pipe 1 is fixed and fixed with a shadowless lamp rotating arm, a lining ring 7, a connecting bush 3 and a limiting screw are installed on the T-shaped shaft 2, a damping screw 5 is installed on the connecting bush 3, the connecting bush 3 rotates around the T-shaped shaft 2, the tightness of rotation of the connecting bush 3 and the T-shaped shaft 2 can be adjusted by adjusting the damping screw 5, and the upper pipe 1 is sleeved on the connecting bush 3 and fixed through four half countersunk head screws during installation. The number of the half countersunk head screws is large during the installation of the structure, the screw holes are inconvenient, the damping screws 5 can not be adjusted after the upper pipe is fixed by the half countersunk head screws 8, and the damping screws 5 can be adjusted only by detaching the upper pipe by detaching the half countersunk head screws after the damping screws are needed to be adjusted after a period of use.
SUMMERY OF THE UTILITY MODEL
Not enough to the above among the prior art, the utility model provides a shadowless lamp balance arm connection structure, its simple structure, convenient operation detects the accuracy, convenient popularization.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a shadowless lamp balance arm connection structure, includes top tube, T type axle and connecting bush, connecting bush cup joints epaxially at T type, the top tube cup joints in connecting bush's the outside, be equipped with the connecting piece on the outer wall of top tube and be connected with connecting bush, be equipped with damping screw and the inconsistent setting of T type axle in relative screw thread through-hole and the screw thread through-hole on top tube and the connecting bush, T type axle stretches into the upper pipe end and the outside is equipped with the locating part.
As an improvement, the damping screws are arranged in an annular array.
As an improvement, the connecting piece is a countersunk head thread piece, and the number of the connecting pieces is two oppositely arranged.
The utility model has the advantages that:
the utility model discloses can adjust the damping screw after the structural mounting and realize the rotatory elasticity of T type axle, and the damping screw of old structure can 'T adjust after the installation, can' T confirm the elasticity of damping screw again before the installation. Simple structure after the improvement originally through four half countersunk head screw fixation, now only need two hexagon socket head cap fastening screw, unable regulation after original damping screw installation, not only can adjust but also it plays a fixed action for top tube and connecting bushing after current installation, has accomplished two kinds of effects of a screw, has not only solved not enough of previous design and has also practiced thrift the cost simultaneously, has brought very big facility for installation and later stage debugging.

1-upper tube, 2-T type axle, 3-connecting bush, 4-connecting piece, 5-damping screw, 6-position limiting piece, 7-lining ring, 8-half countersunk head screw.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.
As shown in fig. 1-2, a shadowless lamp balance arm connection structure, includes top tube 1, T type axle 2 and connecting bush 3, connecting bush 3 cup joints on T type axle 2, top tube 1 cup joints in the outside of connecting bush 3, be equipped with connecting piece 4 on the outer wall of top tube 1 and be connected with connecting bush 3, be equipped with relative screw through-hole and the screw through-hole on top tube 1 and the connecting bush 3 and be equipped with damping screw 5 and the inconsistent setting of T type axle 2, T type axle 2 stretches into top tube 1 end and the outside and is equipped with locating part 6.
The damping screws 5 are arranged in an annular array.
The connecting pieces 4 are countersunk head thread pieces and are two oppositely arranged.
In the use process of the device, the T-shaped shaft 2 is provided with the connecting bushing 3 and a limiting screw, and the limiting part 6 (screw) is used for preventing the connecting bushing 3 from falling off from the T-shaped shaft 2 when the T-shaped shaft 2 rotates, so that the limiting effect is achieved. When the upper pipe 1 is installed, two hexagon socket head cap screws are installed, and then the damping screws 5 are installed, so that the tightness of the T-shaped shaft 2 in rotation can be realized by adjusting the damping screws 5 after the structure is installed, the damping screws 5 of the old structure cannot be adjusted after the structure is installed, and the tightness of the damping screws 5 cannot be determined before the installation. Simple structure after the improvement originally through four half countersunk head screw fixings, now only need two connecting pieces 4 (hexagon socket head cap fastening screw), unable regulation after original damping screw 5 installation, not only can adjust but also it plays a fixed action for top tube 1 and connecting bush 3 after current installation, has accomplished two kinds of effects of a screw, has not only solved not enough of previous design and has also practiced thrift the cost simultaneously, has brought very big facility for installation and later stage debugging.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
