Abstract
The utility model discloses a brightness-adjustable telescopic pointer. The pointer comprises a telescopic pipe body and a casing; a battery chamber for mounting a battery is arranged at the lower part of the casing; a heat dissipation base plate is fixed to the middle part of the casing; a laser lamp is mounted on the heat dissipation base plate; a pair of corresponding chutes are formed in the inner wall of the casing; an adjustable lens frame is mounted on the chutes; a convex lens is mounted in the adjustable lens frame; a sliding block is arranged at one end of the adjustable lens frame, and an adjustable push handle penetrating through one chute is arranged at the other end of the adjustable lens frame; a concave lens is fixedly mounted at the end opening of the top end of the casing. The brightness-adjustable telescopic pointer, disclosed by the utility model, solves the problem that the traditional laser lamp is overly low in brightness so as not to well point teaching contents, a teacher can voluntarily adjust the degree of the brightness and clearly points the teaching contents, as a result, students' attention can be easily attracted, the practicability is high, and the brightness-adjustable telescopic pointer is worthy of popularization.
Description
Technical field
The utility model relates to a kind of teacher's pointer, relates in particular to a kind of flexible teacher's pointer of adjustable light size.
Background technology
At present, teacher often needs to use electronic teacher pointer in teaching now, electronic teacher pointer can help teacher in classroom, to use laser lamp to give directions the content of courses at a distance, and the bright bright spot of the ejaculation of existing laser lamp is very little, student is once not noting being not easy to find this bright spot, and serve as a teacher while needing the content of indication a lot, such sparklet can not meet actual needs completely, caused the problem that can not well indicate the content of courses, to teacher, bring a lot of troubles like this, also caused a lot of puzzlements to student.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of flexible teacher's pointer of adjustable light size.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of flexible teacher's pointer of adjustable light size, comprise telescopic body and be located at the housing of the column type of body bottom, the bottom of described housing is for installing the battery compartment of battery, the middle part of this housing is fixed wtih heat-radiating substrate, on described heat-radiating substrate, laser lamp is installed, described laser lamp is electrically connected to described battery, and the switch of battery is located at the outside of described battery compartment; On the inwall of described housing, a pair of corresponding chute, is provided with adjusting picture frame on described chute, in described adjusting picture frame, convex lens is installed, and one end of described adjusting picture frame is provided with slide block, and the other end is provided with the adjusting passing from chute and pushes away handle; The port, top of described housing is fixedly mounting concavees lens.
Compared with prior art, when the utility model is used, not only can use telescopic tube directly to indicate the content of courses, and can use adjusting to push away the size that handle regulates the light bright spot of laser lamp ejaculation, indicate accurately the content of courses of the required indication of teacher, improve teacher's efficiency of teaching, solve the light size that traditional laser lamp sends too small, can not well indicate the problem of the content of courses, and practical, easy to carry, be worthy to be popularized.

Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1,2 and 3, the flexible teacher's pointer of the adjustable light size the utility model proposes, comprise that telescopic body 1 is located at the housing 2 of the column type of body 1 bottom, the bottom of housing is for installing the battery compartment 21 of battery, the middle part of this housing is fixed wtih heat-radiating substrate 22, laser lamp 3 is installed on heat-radiating substrate 22, and laser lamp 3 is electrically connected to battery, and the switch 6 of battery is located at the outside of described battery compartment 21; A pair of corresponding chute 23 on the inwall of housing, wherein the chute on one side is U-shaped groove structure, and the chute of another side runs through whole housing, on chute 23, be provided with and regulate picture frame 4, regulate in picture frame convex lens 41 are installed, regulate one end of picture frame to be provided with slide block 42, slide block 42 correspondences are arranged in the chute of U-shaped groove structure, the other end is provided with from running through the adjusting that the chute 23 of housing passes and pushes away handle 43, adjusting pushes away handle 43 and is L-type, promotion adjusting pushes away 43 of handles and can drive convex lens 41 to move forward and backward, thus light regulating focal length; The port, top of housing is fixedly mounting concavees lens 5.
In the utility model, housing 2, battery compartment 21, heat-radiating substrate 22 is all column type, during concrete use, flexible body 1 can directly help teacher to indicate the content of courses, and open laser lamp 3, light is penetrated on convex lens, convex lens are concentrated light, on directive concavees lens, concavees lens scattered beam, bright bright spot is beaten on blackboard, now ejection forward or backward regulates and pushes away handle 43, before while pushing away the bright spot of light become large, the content of indication is more, during pusher, the bright spot of light diminishes, the content of courses of indication still less, teacher can regulate according to the actual needs, convenience very.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
