Description

Technical Field

[0001] The invention relates to the technical field of electronic level lighting, in particular to an electronic level lighting device used in a cave. Background Art

[0002] The stripe code of the level ruler is used for electronic scanning during observation with the electronic level. During observation, after automatic focusing and automatic leveling, the light image information received by the telescope is converted into a film image signal and transmitted to the information processor for correlation processing with the original source information of the stripe code of the level ruler in the machine, so that the reading at the horizontal line of sight on the level ruler is obtained. However, when this instrument is used in a tunnel or in dark conditions, the telescope often cannot receive light image information due to light reasons, resulting in measurement failure. Therefore, when the electronic level is used at night or in corridors, caverns and other environments with weak or even no light, two additional assistants are required. The two are responsible for the erection of the level ruler and lighting respectively. The centering of the level bubble on the back of the level ruler also requires lighting assistance, which not only increases the labor cost, but also the electronic level is sensitive to the light intensity of the bar code ruler. Therefore, the person responsible for lighting is required to have certain work experience and to accurately grasp the angle and position of the light, otherwise it will increase the reading time and difficulty of the electronic level and significantly reduce the measurement efficiency.

[0003] In response to the above problems, the existing improvement technology adopts the method of directly adding light strips and batteries to the level ruler, but this undoubtedly increases the weight of the level ruler, and the light strip will also occupy the touchable area of ​​the level ruler, which is not conducive to the person holding the ruler. Secondly, for first-class measurement or measurement routes with small vertical displacement, it is not necessary for the entire ruler to light up, which can easily cause a waste of resources. In addition, some improvement technologies will use the method of reinstalling and configuring the lighting device to illuminate the level ruler, but the installation, disassembly and adjustment process are very cumbersome, the stability needs to be further improved, and the overall convenience of use is low.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] See also Figure 1 and Figure 2, an electronic level instrument lighting device for caverns, including a stable connection mechanism 1, the stable connection mechanism 1 includes a box seat 102 for elastically slidingly setting a card 101, for the convenience of subsequent understanding, it is proposed to divide the card 101 into a card 1 1011 and a card 2 1012, the card 1 1011 and the card 2 1012 are both centrally symmetrically arranged, and the symmetrical card 1 1011 and the symmetrical card 2 1012 are perpendicularly distributed to each other, and a reinforcement locking assembly 103 is arranged between the symmetrical card 1 1011 and the symmetrical card 2 1012, and the reinforcement locking assembly 103 includes a connecting gear 113 and The locking rod 123 meshed with the connecting gear 113 is slidably connected to the box seat 102 and a locking member 133 is threadedly connected to the locking rod 123. The locking member 133 is located outside the box seat 102. The connecting gear 113 is respectively meshed and connected between the corresponding symmetrical clamping member 1011 and the symmetrical clamping member 2 1012. The symmetrical clamping member 2 1012 is provided with an adjustable locking mechanism 2. The adjustable locking mechanism 2 includes a connecting frame 201 and a connecting seat 204 for connecting the connecting frame 201 with the clamping member 2 1012. The end of the connecting frame 201 away from the connecting seat 204 is used for The mounting end for installing the lighting source is an existing clamping head, and the other end is a connecting end of an annular structure. The connecting end is rotatably connected to the connecting seat 204. The connecting seat 204 is provided with an inner support reinforcement component 202 and a side pressure reinforcement component 203. The inner support reinforcement component 202 is located in the connecting end. During the assembly process, it is only necessary to install the lighting source on the mounting end of the connecting frame 201 and put the present invention on the top of the level ruler, and then lock it to quickly and firmly connect the level ruler and the device together, and then rotate the connecting frame 201 to adjust the angle of the lighting source so that the lighting source on the rear side is aligned with the level bubble on the level ruler. Then, the side pressure reinforcement component 203 fixes the position of the lighting source by limiting and fixing the connecting frame 201, and during the process of limiting and fixing the side pressure reinforcement component 203, the inner support reinforcement component 202 is simultaneously driven to limit and fix the connecting frame 201, which effectively improves the firmness of the position of the lighting source, and the entire fixing process can be completed quickly. The adjustment and fixing process of the front lighting source is the same as above, and during the disassembly process, you only need to release the lock to quickly complete the disassembly. Rapid assembly and disassembly can effectively improve the measurement efficiency, and the stable connection state can effectively improve the accuracy and quality of the measurement work.

[0023] See also Figure 1-Figure 3 During the sleeve connection process, the clamp 1 1011 and the clamp 2 1012 respectively clamp and limit the level ruler from the front, back, left, and right directions. At this time, the level ruler and the device are in a preliminary connection state, such as Figure 2As shown, the symmetrical clamp 1 1011 limits and clamps the level rod from the left and right sides, and the symmetrical clamp 2 1012 limits and clamps the level rod from the front and back sides, and under the restriction of the connecting gear 113, the symmetrical clamp 1 1011 and the symmetrical clamp 2 1012 always maintain a state of synchronous reverse sliding. Therefore, in the initial connection state, the clamp 1 1011 and the clamp 2 1012 are both in a centered position state based on the level rod. On the one hand, it is beneficial to improve the stability of the connection state. On the other hand, the symmetrical clamp 2 1012 is in a precisely centered position state based on the level rod to provide a lighting source. It provides a precise position reference, because the positions of the level bubble and the scales on the level rod relative to the level rod are fixed, so during the rapid assembly of the present invention and the level rod, the lighting source will be automatically limited with the level rod as a reference. After limiting, it is only necessary to rotate the connecting frame 201 up and down to adjust the angle of the lighting source to align with the level bubble or the scales on the level rod, quickly meeting the measurement needs and further effectively improving the measurement efficiency. After completing the angle adjustment, the side pressure reinforcement assembly 203 and the internal support reinforcement assembly 202 quickly lock the connecting frame 201, so that the lighting source can be firmly in the current lighting position.

[0024] See also Figure 3 and Figure 4 The side pressure reinforcement assembly 203 includes a side pressure plate 213 and a center locking column 223 threadedly connected to the side pressure plate 213. The center locking column 223 is rotatably connected to the connecting seat 204. The side pressure plate 213 is slidably connected to the connecting seat 204 along the axial direction of the center locking column 223. The inner support reinforcement assembly 202 includes an inner support seat 222 slidably provided with a plurality of inner support members 212. The inner support members 212 slide along the radial limit of the annular structure end of the connecting frame 201. A control ring 242 with an inclined limit surface 232 is slidably provided on the inner support seat 222. The control ring 242 is fixedly connected to the side pressure plate 213 and the control ring 242 slides along the axial direction of the annular structure end of the connecting frame 201. Figure 4As shown, the connecting frame 201 and the connecting seat 204 are frictionally connected. When the connecting frame 201 adjusts the lighting source to a suitable angle, it stops rotating, and then the central locking column 223 is rotated to make the side pressure plate 213 slide toward the connecting frame 201 and press it to limit the position. At the same time, as the side pressure plate 213 moves, the control ring 242 moves accordingly. During the movement, the inner support member 212 is supported and limited from the inside to the outside of the annular structure end of the connecting frame 201 through the inclined limiting surface 232. The side pressure plate 213 and the central locking column 223 are threadedly connected, which can immediately The pressure plate 213 is locked in the current position, so that the lighting source can be locked in the current position quickly and stably, which is beneficial to further improve the efficiency of the measurement work and the stability of the measurement process. Among them, the inner support member 212 is a limit block with a rubber layer on the end, and the inclined limit surface 232 includes an inclined area and a horizontal area. During the movement of the control ring 242, the inclined area first contacts with the inner support member 212 and controls the sliding of the inner support member 212. Then, the horizontal area contacts with the inner support member 212 to stably keep the inner support member 212 in the current limit state, thereby further improving the stability of the limit fixation.

The frame-type limit block 333 is a frame-shaped structure and the limit surface is inclined. The frame-type limit block 333 is fixedly connected to the first connecting member 301. When the limit frame 313 is pulled down and the frame-type limit block 333 is limited, the first connecting member 301 and the second connecting member 302 are both in the tension limit. The locking state of the position, at this time, the two are in a relatively fixed connection state with the bracket 4, and with the cooperation of the limit frame 313 and the frame limit block 333, the first connecting member 301 is quickly limited and tensioned from five directions of front, back, left, right and upper side at the same time, so that the first connecting member 301 and the mounting seat 5 are in a relatively fixed state, and the corresponding box seat 102 and the bracket 4 are in a relatively fixed state, which is convenient for the level ruler to be quickly and firmly connected with the box seat 102, and the relatively fixed state is conducive to improving the accuracy of the initial position of the level ruler. When the level ruler and the box seat 102 are firmly connected together and the angle of the illumination source is adjusted and the measurement is carried out, the limit frame 313 is pulled up to separate the limit frame 313 from the frame limit block 333. At this time, the level ruler can flexibly adjust the measurement state during the measurement process, and the illumination source and the level ruler are always in a stable position state during the adjustment process, which not only improves the measurement accuracy and flexibility, but also improves the measurement process. , It is conducive to quickly completing the measurement work.

At this time, the limit frame 313 is stably in the current state, and the limit frame 313 can be stably and smoothly controlled to move up and down and locked, thereby improving the stability of its position state.
