Description

Technical Field

[0001] The utility model relates to the technical field of optical machinery, and particularly relates to a mirror bracket. Background Art

[0002] With the development of optoelectronic products, mirror mechanisms are widely used in military and civilian fields. When conducting optical convergence path experiment tests, it is often necessary to precisely adjust the angle of the mirror. The current common method for adjusting the mirror mechanism is to adjust the angle by adding adjustment shims, which cannot meet the requirement of precise angle adjustment. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a mirror bracket, which can achieve precise angle adjustment through the angle locking method and the micro deviation correction method of elastic pins.

[0004] To achieve the above purpose, the utility model provides a mirror bracket, which includes a fixed frame. A mirror base is rotatably installed on the fixed frame, and a mirror is fixedly installed on the mirror base. An angle adjustment mechanism is arranged between the fixed frame and the mirror base; the angle adjustment mechanism includes a turntable fixed at one end of the central axis of the mirror base. Positioning grooves are evenly arranged on the circumference of the turntable. An elastic pin is arranged on the fixed frame. The upper end of the elastic pin extends out of the fixed frame, and its bottom is inserted into any one of the positioning grooves; a scale disk is arranged on the fixed frame around the central axis, and a pointer is arranged on the central axis corresponding to the scale disk.

[0005] After adopting the above structure, by pulling out the elastic pin upwards, the bottom of the elastic pin is pulled out of the positioning groove, and then the turntable is rotated to realize the rotation of the mirror base. By reading the value of the scale disk, continuous and precise angle adjustment can be achieved. When the angle is adjusted, the elastic pin is released, and the bottom of the elastic pin is inserted back into the corresponding positioning groove, thereby realizing angle locking. Through this structure, continuous and precise adjustment of the mirror angle is achieved, and the angle adjustment is convenient and fast.

[0006] To facilitate the replacement of the mirror, the mirror is detachably installed on the mirror base.

[0007] To achieve the quick installation of the mirror and ensure firm and stable installation, a fixed seat is detachably installed on the mirror base. A groove is arranged on the fixed seat, and the mirror is snapped into the groove. A pressing plate is fixed on the groove, and the pressing plate clamps the mirror tightly.

[0008] To achieve micro angle correction, the positioning groove is a toothed groove.

[0009] To facilitate the rotation of the turntable, a knob is arranged at the central axis of the turntable.

[0010] To increase the friction of the knob and facilitate exerting force, hand patterns are arranged on the knob.

[0011] To protect the angle adjustment mechanism, a protective cover is provided outside the turntable and the elastic pin. The protective cover is fixed on the fixed frame, and the knob extends out of the protective cover.

[0012] To achieve heat dissipation, hollow holes for heat dissipation are provided on the mirror base corresponding to the back of the reflecting mirror.

[0013] To enable the optical path to pass through at a downward viewing angle, a through hole is provided at the bottom of the fixed frame.

[0014] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] A reflecting mirror bracket of the present utility model solves the technical problem that the reflecting mirror bracket in the prior art cannot meet the precise angle adjustment. By pulling out the elastic pin upward, the bottom of the elastic pin is pulled out of the positioning groove, and then the turntable is rotated to realize the rotation of the mirror base. By reading the value of the scale disk, the precise angle adjustment is realized. When the angle is adjusted, the elastic pin is loosened, and the bottom of the elastic pin is inserted back into the corresponding positioning groove, thereby realizing the angle locking. Through this structure, the precise adjustment of the angle of the reflecting mirror is realized, and the angle adjustment is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present utility model will be further described below with reference to the accompanying drawings.

[0021] All the orientations mentioned in this specification are based on the orientation of a reflecting mirror bracket of the present utility model during normal operation, without limiting its orientation during storage and transportation. It only represents the relative positional relationship and does not represent the absolute positional relationship.

[0022] As Figure 1 , Figure 2 and Figure 3 collectively shown, a mirror bracket includes a fixing bracket 1. An installation hole is provided at the bottom of the fixing bracket 1 for fixing to the reflection optical path. A mirror base 2 is rotatably installed on the fixing bracket 1, and a mirror 21 is fixedly installed on the mirror base 2. In order to facilitate the replacement of the mirror 21, the mirror 21 is detachably installed on the mirror base 2. The preferred installation method in this embodiment is that a fixing base 22 is detachably installed on the mirror base 2, and the fixing base 22 is detachably installed on the mirror base 2 through bolts.

[0023] A groove 221 is provided on the fixing base 22, and the mirror 21 is snapped into the groove 221. A pressing plate 222 is also provided in the groove 221. A threaded hole is provided on the fixing base 22, and a pressing bolt 223 is tightened in the threaded hole. The pressing plate 222 is pressed in the groove 221 through the pressing bolt 223, so as to clamp the pressing plate 222. By rotatably installing the mirror base 2 on the fixing bracket 1, the mirror base 2 can be directly replaced according to different mirrors 21, improving the application range of the device. By providing a groove 221 on the fixing base 22, the positioning of the mirror 21 is facilitated. By providing the pressing plate 222, the position of the mirror 21 is more stable.

[0024] An angle adjustment mechanism 3 is provided between the fixing bracket 1 and the mirror base 2; the angle adjustment mechanism 3 includes a turntable 31 fixed to one end of the central axis 20 of the mirror base 2. Positioning grooves 311 are evenly provided on the circumference of the turntable 31. In this embodiment, in order to achieve the correction of micro angles and prevent the subsequent elastic pin 32 from not being able to be snapped into the positioning groove 311, the positioning groove 311 is a toothed groove. In practical applications, a circular groove, a conical groove or a square groove can also be used. The bottom of the elastic pin 32 is provided with a toothed block that cooperates with the toothed groove. A slideway is provided on the fixing bracket 1, and the elastic pin 32 is slidably installed in the slideway. The elastic pin 32 is successively a limit head 321, an elastic body 322 and a positioning block 323 from top to bottom. The limit head 321 at the upper end of the elastic pin 32 extends out of the fixing bracket 1, so as to facilitate pulling by a person; the limit head 321 is stuck at the upper end of the slideway, so as to achieve the limiting effect. The elastic body 322 is slidably installed in the slideway, and the positioning block 323 is inserted into the positioning groove 311. A return spring 324 is clamped between the elastic body 322 and the fixing bracket 1. Under the action of the return spring 324, the positioning block 323 is inserted into the positioning groove 311.

[0025] When the angle of the mirror 21 needs to be adjusted, the elastic pin 32 is pulled upward by hand, and the positioning block 323 is pulled out of the positioning groove 311, so that the locking is released; when the angle is adjusted, the elastic pin 32 is released, and under the action of the return spring 324, the positioning block 323 is inserted into the positioning groove 311, so as to achieve locking.

[0026] To protect the internal structure, a protective cover 36 is provided outside the turntable 31 and the elastic pin 32, and the protective cover 36 is fixed on the fixing bracket 1. A knob 37 is fixed at the central axis 20 of the turntable 31, and the knob 37 extends out of the protective cover 36.

[0027] To achieve precise angle control, a scale disk 34 is provided outside the protective cover 36 around the central axis 20, and a pointer 35 corresponding to the scale disk 34 is provided on the knob 37.

[0028] To increase friction and facilitate exerting force on the knob 37, fingerprints are provided on the knob 37.

[0029] To dissipate heat from the mirror 21, hollow holes 201 for heat dissipation are provided on the mirror base 2 corresponding to the grooves 221.

[0030] To enable the light path to pass through under a top-down view, a through hole 11 is provided on the fixing bracket 1. When the light path irradiates from below, such as when the mirror 21 is refracted at a 45° angle, the through hole 11 avoids the obstruction of the fixing bracket 1.

[0031] Adjustment process of a mirror bracket of the present utility model:

[0032] Installation of the mirror:

[0033] Snap the mirror 21 into the groove 221, then snap the pressure plate into the groove 221, and screw the compression bolt 223 into the fixing seat 22 in sequence; then install the fixing seat 22 on the mirror base 2.

[0034] Angle adjustment of the mirror:

[0035] By pulling out the elastic pin 32 upward, the bottom of the elastic pin 32 is pulled out of the positioning groove, and then the turntable 31 is rotated to realize the rotation of the mirror base 2. By reading the value of the scale disk 34, continuous and precise angle adjustment is achieved; when the angle is adjusted, release the elastic pin 32, and the bottom of the elastic pin 32 is inserted back into the corresponding positioning groove, thereby realizing angle locking.
