Abstract
The utility model relates to a limiting device for a rotating body of an operating shadowless lamp. The limiting device comprises rolling bearings, rotating sleeves and a main shaft, wherein the upper end and the lower end of the main shaft are sleeved by the rolling bearings; a limiting ring is arranged on the main shaft between the rolling bearings at the upper end and the lower end in a sleeving manner; the rotating sleeves are arranged on the rolling bearings in a sleeving manner; the inner sides of the rotating sleeves are provided with first limiting screws; a first limiting stopper is arranged outside the main shaft; a limiting sleeve is arranged at the lower end of the first limiting stopper; a second limiting stopper is arranged at the lower end of the limiting sleeve; the first limiting screw extends to be just in contact with the second limiting stopper; and a second limiting screw is in threaded connection to the inner wall of the main shaft. The limiting device has the advantages of simple structure and practical functions, can rotate for an angle larger than 360 degrees, and cannot generate the wire winding phenomenon.
Description
Technical field:
The utility model designs a kind of operation shadowless lamp rotary body stopping means.
Background technology:
Operation shadowless lamp is applicable to the various operation illumination needs in medical institutions' operating room.Built-in camera carries out image transmitting and is used for remote network control and monitoring video and teaching usefulness.Built-in camera shadowless lamp rotary body partly need to be worn 8 lines, and traditional operation shadowless lamp rotary body transmits by the conducting block conductive ring, and can only transmit 3 lines, if wear 8 lines, just can only reduce the anglec of rotation, affects product function.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of anglec of rotation greatly, not damage wire, and flexibly operation shadowless lamp rotary body stopping means moves.
The purpose of this utility model is achieved through the following technical solutions: a kind of operation shadowless lamp rotary body stopping means, comprise rolling bearing, pivoted housing and main shaft, cover has rolling bearing at the up and down two ends of main shaft, main shaft cover limited location cover between the rolling bearing at two ends up and down, pivoted housing is enclosed within on the rolling bearing at two ends up and down, be provided with the first stop screw in the pivoted housing inboard, be provided with the first positive stop in the main shaft outside, lower end at described the first positive stop is provided with stop collar, be provided with the second positive stop in the stop collar lower end, the length that the first stop screw stretches out can just be run into the second positive stop, has been threaded connection the second stop screw at the inwall of main shaft.
The utility model compared with prior art has the following advantages:
By on shadowless lamp rotary main shaft and pivoted housing, increasing respectively stop screw, increase spacing collar on the main shaft and reach the spacing of the anglec of rotation, do not affect product function, realized that the anglec of rotation is greater than 360 ° effect.
Description of drawings:
Fig. 1 is device schematic diagram of the present utility model;
Fig. 2 is that A of the present utility model is to the device schematic diagram;
Number in the figure: 1-rolling bearing, 2-pivoted housing, 3-the first stop screw, 4-the first positive stop, 5-stop collar, 6-the second positive stop, 7-the second stop screw, 8-main shaft.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Show a kind of operation shadowless lamp rotary body of the utility model stopping means such as Fig. 1, comprise rolling bearing 1, pivoted housing 2 and main shaft 8, cover has rolling bearing 1 at the up and down two ends of main shaft 8, main shaft 8 cover limited locations covers 5 between the rolling bearing 1 at two ends up and down, pivoted housing is enclosed within on the rolling bearing at two ends up and down, be provided with the first stop screw 3 in the pivoted housing inboard, be provided with the first positive stop 4 in main shaft 8 outsides, be provided with stop collar 5 in the lower end of the first positive stop 4, be provided with the second positive stop 6 in stop collar 5 lower ends, the length that the first stop screw 3 stretches out can just be run into the first positive stop 4, has been threaded connection the second stop screw 7 at the inwall of main shaft 8.
When pivoted housing 2 rotates in the direction of arrows, when turning to certain angle, the first stop screw 3 is run into the first positive stop 4 first, drive stop collar 5 and rotate together, when turning an angle, the second positive stop 6 is run into the second stop screw 7 again, at this moment, pivoted housing 2 forwards maximum angle to, can't be rotated further, and the size of rotational angle can be regulated according to the second installation site of stop screw 7 on axle.
The utility model is that the lamp holder with built-in camera system also can rotational angle, and rotational angle is greater than 360 °, and can regulate, and does not decrease line.
