DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the prior art, such as Figure 1 As shown, when the curing lamp is not in use, the handle 201 of the curing lamp is generally inserted into the placement slot of the dental chair 1. In this way, when other instruments are taken or the dental chair 1 is vibrated, the curing lamp is easily detached from the placement slot. In actual operation, although a protective cover is provided on the light guide rod 202, there is still a possibility that the light guide rod 202 and the light shielding sheet 203 are broken.

[0025] like Figure 2-Figure 5 As shown, the utility model provides a technical solution: a protective cover of a dental chair light curing lamp, comprising a first rubber protective cover 3 and a second rubber protective cover 4, the first rubber protective cover 3 and the second rubber protective cover 4 are integrally formed, the first rubber protective cover 3 and the second rubber protective cover 4 are sleeved on the rod body of the light guide rod 202, and are used to prevent dust and protect the light guide rod 202.

[0026] like Figure 3 and Figure 4 As shown, two annular grooves are provided in the middle of the second rubber protective sleeve 4, and a movable groove 501 is provided on the same side of the two annular grooves. A connecting rope 505 is provided on the side of the movable groove 501, and the two ends of the connecting rope 505 are respectively fixed on the side walls of the same side of the two annular grooves. A fastening rope 502 is respectively wound in the two annular grooves. It can be known that one end of the fastening rope 502 is located at one side of the end of the connecting rope 505 and is fixed to the side wall of the annular groove.

[0027] A ring 504 is fixed at the other end of the fastening rope 502. The ring 504 is sleeved on the rope body of the connecting rope 505. The ring 504 is made of a non-elastic material. The preferred material for making the ring 504 is plastic or metal.

[0028] A pull rope 507 made of nylon material is connected to the middle of the rope body of the connecting rope 505. After placing the curing lamp, the pull rope 507 is fixed to the dental chair 1. It should be noted that the length of the pull rope 507 is less than the height between the dental chair 1 and the ground. In this way, when the curing lamp falls, due to the small elasticity of the pull rope 507, the curing lamp will not contact the ground under the pulling of the pull rope 507.

[0029] Specifically, when in use, the first rubber protective cover 3 and the second rubber protective cover 4 are placed on the light guide rod 202, and then the pull rope 507 is fixed to the dental chair 1. When the curing light accidentally falls, the curing light moves downward under the action of gravity. When the curing light moves to the lowest position, Figure 3 and Figure 4As shown, at this time, the pull rope 507 pulls the connecting rope 505, thereby driving the connecting rope 505 to move counterclockwise. When the connecting rope 505 moves counterclockwise, it drives the fastening rope 502 to move counterclockwise through the ring 504. At this time, the fastening rope 502 on the outside of the annular groove squeezes the inner wall of the annular groove, thereby increasing the friction between the second rubber protective cover 4 and the light guide rod 202 (increasing the wrapping force of the second rubber protective cover 4 on the light guide rod 202), effectively preventing the curing lamp from detaching from the protective cover and colliding with the ground under the action of inertia, thereby protecting the light guide rod 202 and the light shielding sheet 203.

[0030] like Figure 4 As shown, in order to prevent the fastening rope 502 from being too loose in the annular groove, a plurality of fixing rings 509 are fixed on the inner wall of the annular groove, and the fixing rings 509 are sleeved on the rope body of the fastening rope 502. When the curing lamp falls, the rope body of the fastening rope 502 outside the annular groove squeezes the fixing rings 509, and the fixing rings 509 squeeze the inner wall of the annular groove, thereby increasing the wrapping force of the second rubber protective cover 4 on the light guide rod 202.

[0031] In order to facilitate the fixation of the pull rope 507 on the dental chair 1, a suction cup 508 is fixed to the other end of the pull rope 507. It should be noted that the set suction cup 508 is only a way to connect the pull rope 507 to the dental chair 1. It can be known that the suction cup 508 can also be replaced with a gasket and the connection between the pull rope 507 and the dental chair 1 can be achieved by bonding the gasket to the dental chair 1.

[0032] In another specific embodiment of the present solution, a movable sleeve 506 is movably connected to the rope body of the connecting rope 505 , and the pull rope 507 is fixed to one side of the movable sleeve 506 .

[0033] In a specific embodiment of this solution, Figure 5 As shown, the inner wall of the second rubber protective cover 4 is integrally formed with a plurality of convex rings 510. The provision of the convex rings 510 further increases the friction between the second rubber protective cover 4 and the light guide rod 202, and more effectively prevents the curing lamp from detaching from the protective cover due to inertia.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
