Abstract
The utility model discloses an adjusting and fixing structure of a zooming lamp. The lamp comprises a lamp holder, a power source device, a tube body, a light-emitting component, a shell and a lens, wherein the lamp holder is connected with the rear end of the tube body; the power source device is arranged in the tube body; the light-emitting component is fixed at the front end of the tube body; the shell is movably sleeved outside the tube body and the light-emitting component; the lens is fixed at the front end of the shell; at least one hard split ring is arranged between the tube body or the light-emitting component and the shell; and normally, the external diameter of the hard split ring is larger than the internal diameter of the shell. As the elastic action of the hard split ring applies a certain damping function to the shell, stepless adjustment of the distance between the shell and the tube body is realized, and the requirement on zooming illumination to the lamp is achieved; a user can flexibly adjust light beam of the lamp according to the actual situation, so that the diversity of the lamp illumination can be improved. The hard split ring has the characteristic of high temperature resistance, thus the influence to the service life of the lamp adjusting function due to the aging problem is avoided.

The specific embodiment
In order further to explain the technical scheme of the utility model, combine accompanying drawing to come the utility model is set forth in detail through specific embodiment below.
See also Fig. 1 to shown in Figure 4, the varifocal light fixture of the utility model comprises: lamp holder 1, supply unit 2, pipe shaft 3, luminescence component 4, shell 5 and lens 6.
The front end of said lamp holder 1 is provided with the connecting portion that cooperates with pipe shaft 3, is buckle 11 here, also can be screw thread, and also is provided with the boss 12 of a spacing shell 5 in the front portion of this lamp holder 1.
Said pipe shaft 3 is a cylindrical shell, and its rear end is provided with the Access Division (not shown) that cooperates with the buckle 11 of lamp holder 1, and front end is provided with the auxiliary section that cooperates with luminescence component 4, is screw thread 31 here, also can adopt the structure of buckle.
Said luminescence component 4 is to comprise a body 41 and be fixed on the illuminator 42 on the body 41, and the rear portion of this body 41 forms necking down and front end through screw thread 411 or Access Division and pipe shaft 3 links together, and other is electrically connected with supply unit 2 by illuminator 42; Body 41 anterior convex edges 412 are the front ends that are against pipe shaft 3, on these convex edge 412 sidewalls, are provided with ring groove 413.Said shell 5 is a cover seat; Its front end fixed lens 6; The rear portion is the outside that is placed on pipe shaft 3 and luminescence component 4; On the inwall at shell 5 rear portions, form the limited step 51 of internal diameter less than convex edge 412 external diameters of luminescence component 4, the internal diameter of limited step 51 front portions and convex edge 412 external diameters of luminescence component 4 are matched in clearance.
The key of the utility model is: between luminescence component 4 convex edges 412 and shell 5, be provided with at least one hard split ring 7; This hard split ring 7 just is equipped in the ring groove 413 of luminescence component 4 convex edges 412; External diameter when visiting hard split ring 7 normalities is the internal diameter greater than shell 5; Hold effect thereby shell 5 is had an elasticity, realize the adjusting location of shell 5 and luminescence component 4.
This hard split ring 7 is to adopt resistant to elevated temperatures material to process, like metal, nylon or glass fibre or the like.
In addition, also be combined with an anti-scald circle 8 at the outer rim place of shell 5 front ends and regulate light fixture so that the user contacts the application of force.
When the light fixture to the utility model carries out focus adjustment; When pulling shell 5 relative pipe shafts 3 outwards move to the greatest limit place, see shown in Figure 2ly, the entire length of light fixture is the longest at this moment; Illuminator 42 is maximum with the focal length of lens 6; Then the light beam that sends of light fixture is an optically focused, has the strong characteristics of remote focusing brightness, is applicable to the remote object of irradiation.
When promoting shell 5 relative pipe shafts 3 and moving inwardly into least limit, see shown in Figure 3ly, the entire length of light fixture is the shortest at this moment; Illuminator 42 is minimum with the focal length of lens 6; Its light beam that sends has the closely big characteristics of emissive surface for astigmatism, is applicable to the irradiation closer object.
Application of force shell 5 again, regulate shell 5 relative pipe shafts 3 and are in the two apart between greatest limit and the least limit time, see shown in Figure 4ly, and then the beam effect of light fixture is between above-mentioned two kinds of limiting conditions.
In a word, the user can select the light beam state of this light fixture according to the actual conditions of self.
Focusing on of the utility model: utilize the elastic reaction of hard split ring 7 that shell 5 is had certain damping action; Realize that the no section of distance is regulated between shell 5 and the pipe shaft 3; Reach the demand of light fixture zoom illumination; Make things convenient for the user according to the actual conditions needs, flexible light fixture light beam, the diversity of raising lamp lighting; And this hard split ring 7 has resistant to elevated temperatures characteristics, avoids problem of aging occurring and influences the service life that the light fixture regulatory work has.
