Description
Technical field
The utility model belongs to the scope of installing shadowless lamp structural behaviour, relates to a dog screw and anti-collision ring, particularly a kind of shadowless lamp lamp holder rotating shaft stopping means in the installation of shadowless lamp lamp holder.
Background technology
Shadowless lamp is a kind of Medical Devices of operative site of throwing light on that are used for, for observing the object in operation.Due in operation, the head of doctor, hand, apparatus may cause shade to operative site, and can eliminate shade with shadowless lamp, ensure doctor can know the organ seen in operation, tissue etc., so shadowless lamp be hospital operating room must Medical Devices.Installing in the lamp holder process of shadowless lamp at present, lamp holder all needs spacing in rotary course, and conventional spacing is all carry out screw or alignment pin is spacing to carry out, but there will be stressed excessive time, the problems such as stop screw fracture.
Utility model content
The purpose of this utility model is to provide a kind of shadowless lamp lamp holder rotating shaft stopping means solving damage parts problem in the use procedure of shadowless lamp lamp holder.
For solving the problems of the technologies described above, the utility model shadowless lamp lamp holder rotating shaft stopping means, comprising: lamp holder rotating shaft, described lamp holder rotating shaft is the cylindrical of hollow, and the sidewall of described lamp holder rotating shaft is provided with the first locating hole run through and the second locating hole; Union elbow, described union elbow is set in described lamp holder rotating shaft, is provided with stopper slot in the outside of described union elbow; Anti-collision sleeve, described anti-collision sleeve is circular arc, and described anti-collision sleeve is arranged on and is formed in cavity between the inwall of described lamp holder rotating shaft and the outer wall of described union elbow; First spacing hole and the second spacing hole, described first spacing hole and described second spacing hole run through and are arranged on described anti-collision sleeve, described first spacing hole and described second spacing hole corresponding with described first locating hole and described second locating hole; Hold-down screw, described hold-down screw is arranged in described first locating hole and described first spacing hole; Stop screw, described stop screw is arranged in described second locating hole and described second spacing hole, and the end of described stop screw stretches in described stopper slot.
In described second locating hole and described second spacing hole, be provided with internal thread, be provided with external screw thread in the outside of described stop screw, described stop screw and described second locating hole and described second spacing hole are spirally connected.
The utility model shadowless lamp lamp holder rotating shaft stopping means, when mounting limit screw or pin, needs increase anti-collision sleeve, avoids the danger that stop screw damages.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model shadowless lamp lamp holder rotating shaft stopping means is described in further detail.
Lamp holder and the fixation of lamp holder support frame, the union elbow of elbow sections is inserted in lamp holder rotating shaft, and then be screwed connection with lamp holder support frame, union elbow and elbow sections motionless, lamp holder becomes to be integrated with lamp holder rotating shaft and rotates simultaneously, and now stop screw moves in the interior groove of union elbow, turn clockwise lamp holder to maximum position time, stop screw end because lamp holder has certain quality, inertia can be produced, so can be impacted; When being rotated counterclockwise lamp holder to maximum position, stop screw end is subject to reverse impact, so repeatedly moves, and stop screw can produce repeated stock, adds the impact that screwing unsettled extension length is long, easily produces fatigue fracture.If stop screw external diameter specification increased, the restriction of installing space and structure can be subject to, so the outside dimension of stop screw can not be increased.
As shown in Figure 1 and Figure 2, the utility model shadowless lamp lamp holder rotating shaft stopping means is that territory increases an anti-collision sleeve 6 between the inwall and the outer wall of union elbow 4 of lamp holder rotating shaft 1, just can prevent the fracture of stop screw 10.Anti-collision sleeve 6 need be arranged on the neutral area in the middle of lamp holder rotating shaft 1 and union elbow 4, the first locating hole 2 is inserted and the first spacing hole 7 is fixed firmly with hold-down screw 9, the position that stop screw 10 is tightened remains unchanged, insert from the second locating hole 3 and the second spacing hole 8, and extend in the stopper slot 5 outside union elbow 4, the screw thread that stop screw 10 is fixing simultaneously lengthens, namely the thread tightened of stop screw 10 is more, when lamp holder turns to end positions, after stop screw 10 is impacted, because stretching out limit part only in the stopper slot 5 of union elbow 4, outside all to be done corresponding fixing, thus effectively protect stop screw 10 because of positive and negative flexural fatigue be repeatedly destroyed.The regular length increasing stop screw 10 reduces jib-length, when solution stop screw 10 head is subject to impacting, and the problem of fatigue fracture, thus protect stop screw 10.Ensure that the reliability that shadowless lamp lamp holder rotates.
The utility model shadowless lamp lamp holder rotating shaft stopping means, when mounting limit screw or pin, needs increase anti-collision sleeve, avoids the danger that stop screw damages.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
