Description

TECHNICAL FIELD

[0001] The utility model belongs to the precise machinery technical field, concretely relates to a high precision monocular observation mirror and tactical helmet connector which reliably connects monocular observation mirror and tactical helmet and can accurately align the eyepiece of observation mirror and pupil of human eye. BACKGROUND

[0002] Tactical helmet is the basic component of modern individual combat system, and its quick release bayonet can install observation, communication, information collection and other technical equipment, so as to effectively liberate hands and improve individual combat capability. Monocular low-light observation mirror is the common configuration of modern tactical helmet, which is connected with the quick release bayonet of tactical helmet through a special connector. Combat personnel can fold up or lay flat the observation mirror through simple operation of the connector, so as to realize quick switching of naked-eye observation and optical observation. The connector has certain angle and position adjustment function, so as to keep appropriate distance between the observation mirror and eyes when the observation mirror is laid flat, and to align the eyepiece of observation mirror and pupil of eyes as much as possible.

[0003] At present, there are many types of tactical helmet connector products, and the structures and functions are basically similar. Although they can meet the basic requirements of installing observation mirror on tactical helmet, they also have problems such as low adjustment precision and poor positioning and directional stability. The position adjustment of common connector is usually realized by rack and pinion locking mechanism, which is locked by fixed rack and movable rack, and the position is adjusted by disengaging the movable rack and then engaging it again after translation by several tooth pitches. The minimum adjustable distance is one tooth pitch. Due to the limitations of processing and assembly technology, the tooth pitch cannot be too small, and the total position adjustment precision is in millimeter level due to the operation error caused by manual control. Because the size of pupil of human eye is also in millimeter level, it is obviously impossible to achieve accurate alignment of the eyepiece of observation mirror and pupil of human eye with the position adjustment precision in millimeter level. Generally, the rack locking device only realizes effective limiting in two directions (such as left and right and front and back), and the upper and lower limiting is realized by friction, so when the load is heavy or the motion inertia is large, the connecting mechanism will have certain shaking, and the shaking amount is related to the gap of parts. The wear caused by long-time shaking will increase the gap, which will eventually reduce the technical performance and service life of the whole mechanism. SUMMARY

[0004] The main purpose of the utility model is to provide a high precision monocular observation mirror and tactical helmet connector which is compact in structure, good in stability and convenient to operate, and can realize quick installation and disassembly of observation mirror, quick folding and laying down of observation mirror, and accurate alignment of the eyepiece of observation mirror and pupil of human eye.

[0005] The utility model discloses a through following technical measures realizes: including helmet bayonet connection mechanism 1, up and down adjusting mechanism 2, turnover mechanism 3, front and back adjusting mechanism 4, left and right adjusting mechanism 5, observation mirror connecting mechanism 6. Figure 1 For the overall effect of connecting tactical helmet and observation mirror.

[0006] Helmet bayonet connection mechanism 1 is multilayer micro-motion mechanism. The bottom layer is the connecting interface of helmet quick-release bayonet, and single-handed simple operation can realize the installation in the helmet quick-release bayonet, automatic locking, and firm cooperation. The top layer of helmet bayonet connection mechanism mainly connects and supports up and down adjusting mechanism and turnover mechanism.

[0007] Up and down adjusting mechanism 2 mainly includes worm 7, worm hand wheel 8, worm wheel 9, screw rod 10, fixed block 11 and sliding block 12, worm hand wheel 8 is installed on worm 7, and worm wheel 9 is coaxial with screw rod 10. Rotating worm hand wheel 8, worm 7 drives worm wheel 9 and screw rod 10 to rotate. The screw thread of screw rod 10 is matched with the screw thread of fixed block 11, and screw rod 10 rotates to generate axial movement and drive sliding block 12 to move up and down. Worm and worm wheel have the characteristics of large transmission ratio, high carrying capacity, stable transmission, self-locking and the like, so that the up and down position adjusting precision of bearing mechanism sliding block 12 is high, stability is good, and the downward sliding caused by load gravity can be effectively inhibited.

[0008] Turnover mechanism 3 shares component sliding block 12 with up and down adjusting mechanism 2, can drive subsequent mechanism to rotate synchronously, can be automatically locked at two limit positions, and can be slightly adjusted in angle after being locked.

[0009] The main functional components of front and back adjusting mechanism 4 are fixed rack 13 and positioning sliding block 14. Fixed rack 13 is approximately rectangular frame structure, and one end is fixedly installed on up and down turnover mechanism 3. Straight teeth are processed on the inner side of two long edges of fixed rack, and the tooth surface and the inner side form a certain inclination, forming an inclined tooth surface. Two positioning sliding blocks 14 have inclined tooth surfaces matched with fixed rack 13, and the positioning sliding block 14 is tightly attached to the tooth surface of fixed rack 13 under the action of spring thrust. The pressure decomposition of the inclined surface makes the front and back, left and right and up and down stability of movable cover plate 15 and other front and back moving components be obtained. The positioning sliding block 14 can be unlocked by being compressed inward, the movable cover plate 15 and other front and back moving components can move forward and backward after being unlocked, and the positioning sliding block 14 is immediately restored to be locked. Front and back adjusting mechanism mainly controls the longitudinal distance between observation mirror and human eye, and the slight change of longitudinal distance has little influence on observation effect, so the longitudinal distance precision requirement is far lower than the horizontal distance precision requirement, and therefore the straight rack scheme with lower precision can be adopted to realize.

[0010] The left-right adjusting mechanism 5 comprises a fixed block 16, a left-right sliding block 17, a screw rod 18 and the like. The fixed block 16 is fixedly connected with the upper cover 15 of the front-rear adjusting mechanism 4. The left-right sliding block 17 is installed in a sliding groove of the fixed block 16. The screw rod 18 is installed in the fixed block 16 and passes through a threaded hole of the left-right sliding block 17. By rotating a screw rod hand wheel 19, the sliding block 17 can be pushed to move leftward or rightward through the threaded cooperation.

[0011] The main body of the observation mirror connecting mechanism 6 is the left-right sliding block 17 of the left-right adjusting mechanism 5, and the function of the left-right adjusting mechanism 5 is to ensure that the monocular observation mirror is accurately positioned, firmly and stably installed and quickly and conveniently disassembled and assembled.

[0012] The application effect of the present application can be known according to the above description. The monocular observation mirror and the tactical helmet connector have a compact overall structure, are light in weight, convenient to operate and stable and reliable in positioning. The front-rear, up-down and left-right position adjustments are respectively implemented by different schemes, and the front-rear adjustment is fast and the up-down and left-right adjustments are high in precision.

After moving a certain distance, the positioning sliders 14 are released, and the front-back position adjusting is realized.
