Description

Technical Field

[0001] This utility model relates to the field of leveling rod fixing technology, and in particular to a leveling rod fixing bracket. Background Technology

[0002] A leveling rod holder is a special tool used to support and fix a leveling rod during leveling. There are various types of leveling rod holders, with the leveling rod holder being one of the most common. It can ensure the stability and verticality of the leveling rod during leveling, thereby improving the accuracy and precision of the measurement.

[0003] Currently, existing leveling rod frames mainly consist of three sets of telescopic support legs and one set of spring clips. During use, workers use the spring clips to fix the leveling rod. However, since the spring clips are located at the top of the frame, the fixing point of the leveling rod is relatively high, and the center of gravity is also relatively high. When subjected to external forces such as wind or slight collisions, it is prone to swaying and tilting, which will affect the fixing effect and verticality of the leveling rod, and thus affect the measurement accuracy. Therefore, we propose a leveling rod fixing bracket to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a leveling rod fixing bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leveling rod fixing bracket includes a support base, with first telescopic rods hinged at equal intervals to the sides of the support base. A spring clip is connected to the top of the support base, and the leveling rod body is held inside the spring clip. A second telescopic rod is connected to the bottom of the support base, and a positioning block is provided at the bottom of the second telescopic rod. A slot is opened inside the positioning block, and a first threaded rod is connected inside the slot through a bearing. A threaded sleeve is fitted on the outside of the first threaded rod, and a clamping plate is connected to the side of the threaded sleeve.

[0007] Preferably, a second threaded rod is vertically connected to the upper side of the positioning block, and a threaded groove adapted to the second threaded rod is provided at the bottom end of the second telescopic rod.

[0008] Preferably, the positioning block has a groove on its front side, and the groove has a horizontal bubble inside.

[0009] Preferably, the horizontal bubble is symmetrically connected to the side with a mounting plate, and the interior of the mounting plate is connected to the inner wall of the groove by bolts.

[0010] Preferably, a rubber sheet is glued to the side of the clamps that are close to each other, and the outer surface of the rubber sheet is provided with anti-slip texture.

[0011] Preferably, the other end of the first threaded rod extends to the outside of the slot and is connected to a rotating disk, and anti-slip strips are evenly distributed on the outer side of the rotating disk.

[0012] Preferably, the bottom end of the positioning block is glued with a rubber pad, and the lower side of the rubber pad is uniformly provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is equipped with positioning blocks and clamps. During use, the positioning blocks and clamps work together to limit and fix the bottom of the leveling rod body, thereby effectively improving the fixation effect of the leveling rod body and preventing the leveling rod body from being easily tilted by external forces during measurement, thus effectively improving the measurement accuracy.

[0015] 2. This device is equipped with a bubble level and a mounting plate. During use, the bubble level allows operators to visually judge the level of the device and make timely adjustments, thereby improving the accuracy of the device during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A leveling rod fixing bracket includes a support base 1. A first telescopic rod 2 is equidistantly hinged to the side of the support base 1. The telescopic principle of the first telescopic rod 2 is existing technology and will not be described in detail here. The adjustable fixing angle of the device can be achieved through the telescopic first telescopic rod 2. A spring clip 3 is connected to the top of the support base 1, and the leveling rod body 4 is clamped inside the spring clip 3. The clamping principle of the spring clip 3 is also existing technology and will not be described in detail here. A second telescopic rod 5 is connected to the bottom of the support base 1, and a positioning block 6 is provided at the bottom of the second telescopic rod 5. The telescopic principle of rod 5 is the same as that of the first telescopic rod 2, which is a relatively mature existing technology. The positioning block 6 has a slot inside, and the first threaded rod 7 is connected to the inside of the slot through a bearing. The outer side of the first threaded rod 7 is fitted with a threaded sleeve 8, and the side of the threaded sleeve 8 is connected to a clamping plate 10. The outer surface of the first threaded rod 7 has two sets of external threads with opposite thread directions. Therefore, during the rotation of the first threaded rod 7, the two sets of first threaded rods 7 can drive the two sets of threaded sleeves 8 to move closer or further away from each other, so as to achieve clamping of the bottom of the leveling rod body 4.

[0023] Furthermore, refer to Figure 3 It can be seen that the upper side of the positioning block 6 is vertically connected to the second threaded rod 14, and the bottom end of the second telescopic rod 5 is provided with a threaded groove that matches the second threaded rod 14. The second telescopic rod 5 is composed of an insert rod and a sleeve rod, wherein the threaded groove is opened at the bottom of the insert rod. Through the cooperation between the second threaded rod 14 and the threaded groove, it is convenient for the staff to remove and replace the damaged positioning block 6 in a timely manner.

[0024] Furthermore, refer to Figure 3 It can be seen that the front of the positioning block 6 has a groove, and the inside of the groove has a level bubble 12. Through the level bubble 12 inside the positioning block 6, the staff can intuitively judge the horizontal state of the device and make timely adjustments.

[0025] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the horizontal bubble 12 is symmetrically connected to the side with mounting plates 13, and the interior of the mounting plates 13 is connected to the inner wall of the groove by bolts. Through the cooperation of the mounting plates 13 and bolts, it is convenient for the staff to disassemble and replace the broken horizontal bubble 12 in a timely manner.

[0026] Furthermore, refer to Figure 3 and Figure 4It can be seen that a rubber plate 11 is glued to the side of the clamping plates 10 that are close to each other, and the outer surface of the rubber plate 11 is provided with anti-slip texture. Through the cooperation of the rubber plate 11 and the anti-slip texture, the fixing effect of the leveling rod body 4 can be improved, and the outer wall of the leveling rod body 4 can be prevented from being crushed.

[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the other end of the first threaded rod 7 extends to the outside of the slot and is connected to a rotating disk 9. Anti-slip strips are evenly distributed on the outer side of the rotating disk 9. With the setting of the rotating disk 9 and multiple sets of anti-slip strips, it is convenient for the staff to quickly drive the first threaded rod 7 to rotate, thereby effectively improving the convenience of using the device.

[0028] Furthermore, refer to Figure 3 It can be seen that the bottom of the positioning block 6 is glued with a rubber pad, and the lower side of the rubber pad is evenly provided with anti-slip texture. The rubber pad at the bottom of the positioning block 6 can protect the bottom of the positioning block 6, effectively preventing its bottom from directly rubbing against the ground or foreign objects. With the anti-slip texture, the stability of the positioning block 6 when placed on the ground can be effectively guaranteed.

[0029] Working Principle: When using this utility model, the operator can first transfer the device to the measurement area, then adjust each set of first telescopic rods 2 to a suitable height, and rotate the first telescopic rods 2 to an inclined position, thereby supporting the support base 1 and the leveling rod body 4. At this time, the operator can judge the level of the device during placement by observing the state of the bubble level 12, and make timely adjustments. After adjustment, the operator can use the spring clip 3 to clamp the leveling rod body 4, and then adjust the second telescopic rod 5 to the desired height. Then, by rotating the rotating disk 9, the operator can drive the first threaded rod 7 to rotate continuously. At this time, the first threaded rod 7 can be threaded with the threaded sleeve 8, so that the two sets of threaded sleeves 8 drive the two sets of clamping plates 10 to move in opposite directions, thereby reinforcing and limiting the bottom of the leveling rod body 4. At this time, the operator can use the leveling measuring equipment to perform measurements. The above is the complete working principle of this utility model.
