Description

Technical Field

[0001] The utility model relates to the technical field of level rods, in particular to an auxiliary lighting and supporting device for a level rod. Background Art

[0002] The level rod is a ruler used for leveling measurement. It is generally used as an indispensable measuring tool in the construction process of water conservancy and hydropower, municipal administration, water environment management, new energy, civil engineering, etc. It is used to transmit the height difference between two points.

[0003] At present, in field work, due to the influence of the gravity of the level ruler itself and the external wind force, the support personnel usually use two support rods to clamp on both sides of the level ruler, and refer to the circular level bubble on the level ruler to keep the level ruler vertical. However, due to external factors and geological reasons, the manual support ruler will cause the ruler surface to shake and tilt, resulting in reading errors. At the same time, in actual work, in order to advance the progress of work, the light is dim and the line of sight is poor when leveling is carried out at night or in corridors and tunnels. Generally, two level ruler lighting personnel are used to illuminate the two level rulers respectively, and this operation increases labor costs. The observer needs to communicate with the level ruler lighting personnel about the lighting position and light intensity of the level ruler, which affects the efficiency of the measurement work.

[0004] In order to improve the shortcomings of the current level ruler lighting and manual support, it is necessary to innovate and improve the existing technology. Therefore, we propose a level ruler auxiliary lighting and support device. Utility Model Content

[0005] The purpose of the utility model is to provide a level rod auxiliary lighting and supporting device to solve the problem mentioned in the above background technology that the existing level rod usually needs to be manually held when in use, and then due to factors such as the ground, it cannot be guaranteed that the level rod can be in an absolutely vertical state, which easily causes errors in the level rod readings, and then artificial auxiliary lighting of the level rod surface increases labor costs and affects the progress of the leveling work.

[0006] In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: a level ruler auxiliary lighting and support device, comprising a level ruler body, an auxiliary box and a positioning seat, the side outer wall of the level ruler body is installed with an auxiliary box, the positioning seat is located on the outside of the level ruler body, the interior of the auxiliary box is provided with a lighting position adjustment mechanism, the interior of the positioning seat is provided with a supporting positioning mechanism, and the outside of the positioning seat is provided with a stabilizing support mechanism.

[0007] Furthermore, the lighting position adjustment mechanism includes an auxiliary support bar, a limit block and a lighting lamp. The auxiliary support bar is connected between the inner walls on both sides of the auxiliary box. The side outer wall of the limit block is provided with a sliding block, and the sliding block is slidably connected to the side outer wall of the auxiliary support bar. The protruding end of the limit block is arranged on the outside of the auxiliary box, and the top outer wall of the limit block is snap-connected with the lighting lamp.

[0008] Furthermore, the side outer wall of the auxiliary support bar is penetrated with limiting threaded holes at equal intervals, the internal threads of the limiting threaded holes are connected to limiting bolts, and the limiting bolts are threadedly connected to the sliding block, and the side outer wall of the lighting lamp is provided with a power supply line.

[0009] Furthermore, the supporting positioning mechanism includes a limiting sleeve, a limiting piston rod and a resistance spring. The limiting sleeves are symmetrically and evenly installed on the inner walls of both sides of the positioning seat. The limiting piston rod is slidably installed inside the limiting sleeve. A resistance spring is connected between the limiting piston rod and the inner wall of the bottom end of the limiting sleeve.

[0010] Furthermore, the supporting and positioning mechanism also includes a positioning support bar and a resisting tooth pad; the protruding end of the limiting piston rod is arranged on the outside of the limiting sleeve, the protruding end of the limiting piston rod is connected to the outer wall of one side of the positioning support bar, and the outer wall of the other side of the positioning support bar is connected to the resisting tooth pad.

[0011] Furthermore, the stable support mechanism includes a positioning block, a limiting shaft, a limiting roller and a telescopic rod. The side outer wall of the positioning seat is symmetrically provided with positioning blocks, the limiting shaft is connected between the two positioning blocks, the limiting shaft is rotatably installed on the outside, and the bottom outer wall of the limiting roller is provided with a telescopic rod.

[0012] Furthermore, the outer wall of the telescopic rod at the bottom end is threadedly connected to a support rod, a rotating wheel is fixedly provided on the outer wall on one side of the support rod, a supporting base plate is fixedly provided on the outer wall on the other side of the support rod, spikes are evenly spaced on the top outer wall of the supporting base plate, a resistance pad is provided on the outer wall of the bottom end of the supporting base plate, and the resistance pad is arranged as an inclined structure.

[0013] A circular level bubble is arranged on the back of the level ruler body.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] 1. When the auxiliary lighting and supporting device of the level rod of the utility model is in use, since the existing level rod usually needs to be held manually when in use, and the ground and other factors cannot ensure that the level rod can be in an absolutely vertical state, it is easy to cause errors in the reading of the level rod. Therefore, the device is provided with a telescopic rod, a support rod, a rotating wheel, a supporting bottom plate, spikes and a contact pad. When the working ground is muddy, the spike end can be inserted into the mud. When the working ground is ordinary cement geology, the contact pad end can be downward. With this design, the device can adapt to different geological conditions and can achieve a good positioning and supporting effect for the level rod. Further, with the setting of the limit sleeve, the limit piston rod, the contact spring, the positioning support strip and the contact tooth pad, since the specifications and models of the level rod are different, the device can achieve a good clamping and positioning effect for level rods of different models and specifications through this design. The overall applicability is wide and the practical effect is good.

[0016] 2. When the auxiliary lighting and support device of the utility model is in use, since the visibility is poor at night, errors are likely to occur when reading the level rod. Therefore, the device has the effect of illuminating and assisting the reading of the level rod through the arrangement of auxiliary support bars, limit blocks, lighting lamps, limit threaded holes and limit bolts. Furthermore, the position of the level rod is adjustable, so that the lighting lamp can be moved to a designated position for lighting, thereby achieving the effect of reducing interference in reading and reducing the cost of manual auxiliary lighting.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Combination Figure 1 - Figure 7 The utility model provides a technical solution: a level ruler auxiliary lighting and support device, including a level ruler body 1, an auxiliary box 2 and a positioning seat 3, the side outer wall of the level ruler body 1 is installed with the auxiliary box 2, the positioning seat 3 is located on the outside of the level ruler body 1, the auxiliary box 2 is provided with a lighting position adjustment mechanism, the positioning seat 3 is provided with a support positioning mechanism, and the outside of the positioning seat 3 is provided with a stabilizing support mechanism.

[0027] The lighting position adjustment mechanism includes an auxiliary support bar 4, a limit block 5 and a lighting lamp 6. The auxiliary support bar 4 is connected between the inner walls on both sides of the auxiliary box 2. The side outer wall of the limit block 5 is provided with a sliding block, and the sliding block is slidably connected to the side outer wall of the auxiliary support bar 4. The protruding end of the limit block 5 is arranged outside the auxiliary box 2, and the top outer wall of the limit block 5 is snap-connected with the lighting lamp 6. The side outer wall of the auxiliary support bar 4 is evenly spaced to penetrate the limiting threaded holes 7. The internal threads of the limiting threaded holes 7 are connected to the limiting bolts 8, and the limiting bolts 8 are threadedly connected to the sliding blocks. The side outer wall of the lighting lamp 6 is provided with a power supply line 9. When the lighting needs to be adjusted for night observation When the lighting lamp 6 is in the position, it is first necessary to unscrew the limit bolt 8 from the inside of the limit threaded hole 7. At this time, the limit block 5 is changed from a locked state to a movable state. After moving the limit block 5 to a suitable position, the limit bolt 8 is screwed into the inside of the limit threaded hole 7 at the corresponding position. When the limit block 5 moves, it will automatically drive the lighting lamp 6 to move and thus complete the adjustment of the vertical position of the lighting lamp 6. When it is necessary to illuminate other positions of the level ruler, it is only necessary to take the lighting lamp 6 out of the inside of the limit block 5 to achieve all-round lighting. The setting of the power supply line 9 here is convenient for powering the lighting lamp 6. It is noted here that the power supply component is pre-arranged inside the auxiliary support bar 4.

[0028] The supporting positioning mechanism includes a limiting sleeve 10, a limiting piston rod 11 and a resistance spring 12. The limiting sleeves 10 are symmetrically and evenly embedded in the inner walls of both sides of the positioning seat 3. The limiting piston rod 11 is slidably installed inside the limiting sleeve 10, and a resistance spring 12 is connected between the limiting piston rod 11 and the inner wall of the bottom end of the limiting sleeve 10.

[0029] The supporting and positioning mechanism also includes a positioning support bar 13 and a resistance tooth pad 14; the protruding end of the limiting piston rod 11 is arranged on the outside of the limiting sleeve 10, and the protruding end of the limiting piston rod 11 is connected to the outer wall of one side of the positioning support bar 13, and the outer wall of the other side of the positioning support bar 13 is connected to the resistance tooth pad 14; when the level ruler needs to be positioned and clamped, the level ruler needs to be first engaged in the middle position of the two resistance tooth pads 14, and then the resistance tooth pad 14 is automatically driven by the resistance force to move the positioning support bar 13, and then the movement of the positioning support bar 13 will automatically drive the limiting piston rod 11 to slide inside the limiting sleeve 10. At this time, the resistance spring 12 is in a contracted state and synchronously generates a reaction force to push the limiting piston rod 11 to move, and then the movement of the limiting piston rod 11 will automatically push the positioning support bar 13 to move, so that the resistance tooth pad 14 is closely attached to the outer wall of the level ruler, thereby achieving the effect of limiting clamping.

[0030] The stable support mechanism includes a positioning block 15, a limiting shaft 16, a limiting roller 17 and a telescopic rod 18. The positioning blocks 15 are symmetrically arranged on the side outer wall of the positioning seat 3. The limiting shaft 16 is connected between the two positioning blocks 15. The limiting roller 17 is rotatably installed outside the limiting shaft 16. The telescopic rod 18 is arranged on the bottom outer wall of the limiting roller 17.

[0031] The outer wall of the telescopic rod 18 at the bottom end is threadedly connected to a support rod 19, a rotating wheel 20 is fixedly arranged on the outer wall of one side of the support rod 19, and a supporting bottom plate 21 is fixedly arranged on the outer wall of the other side of the support rod 19, and spikes 22 are evenly spaced on the top outer wall of the supporting bottom plate 21, and a contact pad 23 is arranged on the outer wall of the bottom end of the supporting bottom plate 21, and the contact pad 23 is arranged in an inclined structure; when it is necessary to support the device body, at this time, it is necessary to first select a suitable fixed end according to the ground conditions, when the ground is loose soil such as mud, When the ground is soft, it is necessary to adjust the spikes 22 to face downward. When the ground is a hard ground such as concrete, it is necessary to adjust the contact pad 23 to face downward. When adjusting, you only need to turn the rotating wheel 20. When the rotating wheel 20 rotates, it will automatically drive the support rod 19 to rotate and then drive the support base plate 21 to flip. Then, when the support base plate 21 flips, the direction of the spikes 22 and the contact pad 23 can be freely adjusted. After adjustment, you need to adjust the length of the telescopic rod 18 according to the length of the level ruler. After the length is adjusted, you can choose a suitable support angle.

[0032] A circular level bubble 24 (which may be the factory-provided circular level bubble 24) is installed on the level ruler body 1; when the positioning of the level ruler body 1 is offset, the verticality of the level ruler supported by the device can be determined by observing the position indicated by the circular level bubble 24.

[0033] The working principle of the utility model is as follows: when the position of the illuminating lamp 6 needs to be adjusted for night observation, at this time, it is first necessary to screw out the limiting bolt 8 from the inside of the limiting threaded hole 7. At this time, the limiting block 5 is changed from the locked state to the movable state. After the limiting block 5 is moved to the appropriate position, the limiting bolt 8 is screwed into the limiting threaded hole 7 at the corresponding position. When the limiting block 5 moves, it will automatically drive the illuminating lamp 6 to move and thus complete the adjustment of the vertical position of the illuminating lamp 6. When it is necessary to illuminate other positions of the level ruler, at this time, it is only necessary to pull the illuminating lamp 6 out of the limiting block 5. All-round lighting can be achieved by taking out the power supply line 9 here, and the arrangement of the power supply line 9 is convenient for powering the lighting lamp 6, wherein the power supply component is pre-arranged inside the auxiliary support bar 4; when the level ruler needs to be positioned and clamped, at this time, it is first necessary to clamp the level ruler to the middle position of the two interference tooth pads 14, and then the interference tooth pads 14 are automatically driven by the interference force to move the positioning support bar 13, and then the movement of the positioning support bar 13 will automatically drive the limiting piston rod 11 to slide inside the limiting sleeve 10, and at this time the interference spring 12 is in a contracted state and synchronously generates a reverse The force pushes the limit piston rod 11 to move, and the movement of the limit piston rod 11 will automatically push the positioning support bar 13 to move, so that the interference tooth pad 14 is closely fitted to the outer wall of the level ruler, so as to achieve the effect of limit clamping; when the device body needs to be supported, at this time, it is necessary to first select a suitable fixed end according to the ground conditions. When the ground is soft geology such as soil, it is necessary to adjust the spikes 22 to face downwards. When the ground is hard ground such as concrete, it is necessary to adjust the interference pad 23 to face downwards. When adjusting, you only need to turn the wheel 20. When the wheel is turned, After the disk 20 rotates, it will automatically drive the support rod 19 to rotate and then drive the support base plate 21 to flip over. Then, when the support base plate 21 flips over, the orientation of the spikes 22 and the contact pads 23 can be freely adjusted. After adjustment, the length of the telescopic rod 18 needs to be adjusted according to the length of the level ruler. After the length is adjusted, a suitable support angle can be selected; when the positioning of the device body is offset, the circular level bubble 24 of the level ruler body 1 will automatically shift to one side. At this time, the verticality of the device support can be judged by observing the position indicated by the circular level bubble 24.
