Description

Technical Field

[0001] The utility model relates to the field of spirit levels, in particular to a spirit level for highway construction equipment. Background Technique

[0002] Highway construction is a complex project. In the early stage, planning and design, surveying and mapping need to be carried out, and materials and equipment need to be prepared. The construction process includes subgrade construction, such as site cleaning, filling and excavation, and construction of drainage facilities; pavement construction covers base course and surface course operations. For asphalt pavements, parameters such as asphalt temperature need to be controlled, and for cement concrete pavements, strength and expansion joints need to be ensured; at the same time, construction of auxiliary facilities is carried out, including traffic safety facilities, improvement of drainage and greening projects. During construction, the quality of materials and the construction process need to be strictly controlled, and the completion acceptance ensures that the highway meets the standards. Professionals in each link need to cooperate closely.

[0003] In highway construction, the spirit level of highway construction equipment plays a crucial role. Among them, an existing spirit level of highway construction equipment includes a device main body and a bubble spirit level. In the on-site rapid inspection link of highway construction, the spirit level of highway construction equipment plays a specific role. Construction workers can use it to judge whether the installation of the curb is roughly horizontal and whether the slope of the temporary drainage facilities is reasonable. The spirit level of this highway construction equipment has the remarkable advantages of being easy to carry and having a relatively low cost.

[0004] However, the construction environment where this spirit level of highway construction equipment is located is often relatively harsh, which makes the spirit level of highway construction equipment often face the situation of being damaged. Moreover, this spirit level of highway construction equipment is usually fixedly installed in the device main body and cannot be replaced. Once it is damaged, it will affect the normal use of the spirit level in the highway construction equipment, and the entire device main body needs to be replaced, thus increasing the construction cost. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a spirit level for highway construction equipment to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A spirit level for highway construction equipment, an installation seat is movably installed inside the device main body, and a fixed block, a bubble spirit level and a protective layer are fixedly installed on the inner wall of the installation seat. A slider is slidably installed at the end of the fixed block, and a convex block and a limiting block are fixedly installed on the outer wall of the slider. A plug pin is fixedly installed at the end of the slider. A sliding groove for the slider and the limiting block to slide is opened inside the fixed block. A telescopic rod fixedly connected with the fixed block is fixedly installed inside the slider, and a spring is sleeved on the outer wall of the telescopic rod. A plurality of groups of positioning holes corresponding to the plug pin are equally angled and opened inside the device main body.

[0007] By adopting the above technical solution, when the bubble level is damaged and needs to be replaced, it is only necessary to manually pinch two sets of protrusions to remove the restrictions of the entire mounting base and related components, and easily take them out for quick replacement without replacing a new device body, thereby greatly saving costs. At the same time, the set transparent protective layer can effectively protect the bubble level and significantly reduce its damage probability. Moreover, the transparent material will not affect the observation of the bubble level at all while playing a protective role. In addition, since multiple sets of positioning holes are arranged at equal angles, only one set of bubble levels needs to be installed on the device body to achieve measurement of horizontal planes at different angles, further reducing cost investment.

[0008] Furthermore, the cross-section of the mounting seat is designed to be circular, the thickness of the mounting seat is the same as the width of the device body, and the mounting seat is located at the center of the device body.

[0009] By adopting the above technical solution, the mounting seat can be rotated in the device body, thereby realizing multi-angle measurement.

[0010] Furthermore, the fixing block is designed to be semicircular corresponding to the mounting seat, and the thickness of the fixing block is smaller than the thickness of the mounting seat, and two groups of fixing blocks are symmetrically arranged in the mounting seat, and the bubble level is located between the two groups of fixing blocks.

[0011] By adopting the above technical solution, the fixing block can better cooperate with the mounting base, which not only ensures the stability of the structure but also does not affect the overall aesthetics. Placing the bubble level between the two sets of fixing blocks can effectively protect the bubble level and reduce interference and damage to it by external factors.

[0012] Furthermore, two groups of the protective layer are symmetrically arranged on both sides of the bubble level, and the outer wall of the protective layer and the outer wall of the fixed block are in the same horizontal plane, and the protective layer is made of transparent material.

[0013] By adopting the above technical solution, the protective layer will not hinder the sliding of the slider and can effectively prevent the bubble level from being hit or scratched by external forces, thereby reducing the probability of damage. While the protective layer of transparent material protects the bubble level, it will not affect the observation of the bubble level at all, ensuring that the user can clearly observe the bubble level and thus accurately perform measurements.

[0014] Furthermore, the cross-section of the slider is designed in a "匚" shape, and two groups of sliders are provided corresponding to the fixed blocks. The protrusions are located on the outer wall of the slider at one end close to the bubble level, and the outer wall of the protrusions is in the same horizontal plane as the outer wall of the device body.

[0015] By adopting the above technical solution, when replacing or adjusting the angle of the bubble level, it can be achieved by manually pinching the protrusion, which is simple and convenient to operate.

[0016] Further, the bolt is arranged on the outer wall of one end of the slider close to the mounting seat, and a through hole corresponding to the bolt is formed on the outer wall of the mounting seat.

[0017] By adopting the above technical solution, the convenience and reliability of the operation are ensured when the angle needs to be adjusted or the bubble level is replaced, and the stability of the device during use is also guaranteed.

[0018] Further, the sliding groove is correspondingly arranged with the slider and the limiting block, one end of the spring is attached to the inner wall of the slider, and the other end of the spring is attached to the outer wall of the sliding groove.

[0019] By adopting the above technical solution, it is ensured that the slider and the limiting block can slide smoothly in the sliding groove without jamming or deviation. The setting of the spring not only improves the convenience of the operation, but also increases the reliability and durability of the device.

[0020] In summary, the main beneficial effects of the present utility model are as follows:

[0021] By providing a mounting seat, a fixing block, a sliding groove, a bubble level, a slider, a convex block, a bolt, a limiting block, a telescopic rod, a spring and a positioning hole, when the bubble level is damaged and needs to be replaced, only by manually squeezing two groups of convex blocks, the entire mounting seat and related components can be released from the restriction, and can be easily taken out for quick replacement without replacing the new device body, which greatly saves the cost. By providing a transparent protective layer, the bubble level can be effectively protected, and the probability of damage to the bubble level is significantly reduced. Moreover, the transparent material does not affect the observation of the bubble level at all while achieving the protection. By arranging multiple groups of positioning holes at equal angles, the device body only needs to install one group of bubble levels to measure horizontal planes at different angles, further reducing the cost investment.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0031] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0032] A level for road construction equipment, as Figure 1 - Figure 7 shown, includes a device main body 1. An installation seat 2 is movably installed inside the device main body 1, and a fixing block 3, a bubble level 4, and a protective layer 5 are fixedly installed on the inner wall of the installation seat 2, which can effectively prevent the bubble level 4 from being impacted or scratched by external forces and reduce the probability of damage. Moreover, the protective layer 5 is made of a transparent material, which can protect the bubble level 4 while not affecting the observation of the bubble level 4 at all, ensuring that the user can clearly observe the bubble level 4 and thus accurately carry out the measurement work. A slider 6 is slidably installed at the end of the fixing block 3, and a convex block 61 and a limiting block 63 are fixedly installed on the outer wall of the slider 6. A plug pin 62 is fixedly installed at the end of the slider 6. A sliding groove 31 for the slider 6 and the limiting block 63 to slide is provided inside the fixing block 3. A telescopic rod 64 fixedly connected to the fixing block 3 is fixedly installed inside the slider 6, and a spring 65 is sleeved on the outer wall of the telescopic rod 64. When the bubble level 4 is damaged and needs to be replaced, only by manually squeezing the two groups of convex blocks 61, the entire installation seat 2 and related components can be released from the restriction, and can be easily taken out for quick replacement without replacing the new device main body 1, greatly saving costs. A plurality of groups of positioning holes 7 corresponding to the plug pin 62 are equiangularly provided inside the device main body 1, so that the device main body 1 only needs to install a group of bubble levels 4 to realize the measurement of horizontal planes at different angles, further reducing the cost investment.

[0033] Please refer to Figure 1 - Figure 7The cross section of the mounting seat 2 is designed to be circular, and the thickness of the mounting seat 2 is the same as the width of the device body 1. The mounting seat 2 is located at the center of the device body 1, so that the mounting seat 2 can rotate in the device body 1, thereby realizing multi-angle measurement.

[0034] See also Figure 1 - Figure 7 The fixing block 3 is designed to be semicircular corresponding to the mounting base 2, and the thickness of the fixing block 3 is less than the thickness of the mounting base 2, and there are two groups of fixing blocks 3 symmetrically arranged in the mounting base 2, and the bubble level 4 is located between the two groups of fixing blocks 3, so that the fixing block 3 can better cooperate with the mounting base 2, which not only ensures the stability of the structure but also does not affect the overall aesthetics. Placing the bubble level 4 between the two groups of fixing blocks 3 can effectively protect the bubble level 4 and reduce interference and damage to it by external factors.

[0035] See also Figure 3 - Figure 7 Two groups of protective layers 5 are symmetrically arranged on both sides of the bubble level 4, and the outer wall of the protective layer 5 is at the same horizontal plane as the outer wall of the fixed block 3, so that the protective layer 5 will not hinder the sliding of the slider 6, and can effectively prevent the bubble level 4 from being hit or scratched by external force, reducing the probability of damage, and the protective layer 5 is made of transparent material. While protecting the bubble level 4, it will not affect the observation of the bubble level 4 at all, ensuring that the user can clearly observe the bubble level 4, thereby accurately performing measurement work.

[0036] See also Figure 1 - Figure 7 The cross section of the slider 6 is designed in a "匚" shape, and two groups of sliders 6 are provided corresponding to the fixed block 3. The protrusion 61 is located on the outer wall of the slider 6 close to the bubble level 4, and the outer wall of the protrusion 61 is in the same horizontal plane as the outer wall of the device body 1, so that when replacing or adjusting the angle of the bubble level 4, it can be achieved by manually pinching the protrusion 61, which is simple and convenient to operate.

[0037] See also Figure 2 - Figure 7 The latch 62 is arranged on the outer wall of the slider 6 close to the mounting seat 2, and a through hole corresponding to the latch 62 is opened on the outer wall of the mounting seat 2, so that the latch 62 can accurately cooperate with the through hole on the mounting seat 2. When the slider 6 slides in the fixed block 3, the latch 62 can flexibly enter and exit the through hole on the outer wall of the mounting seat 2 as the slider 6 moves, thereby realizing the restriction and release of the angle of the mounting seat 2, ensuring the convenience and reliability of operation when the angle needs to be adjusted or the bubble level 4 needs to be replaced. At the same time, the precise correspondence between the latch 62 and the through hole also ensures the stability of the device during use.

[0038] See also Figure 5 - Figure 7, the sliding groove 31 is correspondingly arranged with the slider 6 and the limiting block 63, ensuring that the slider 6 and the limiting block 63 can slide smoothly in the sliding groove 31 without jamming or deviation, making the operation of adjusting the angle of the mounting seat 2 or replacing the bubble level 4 more smooth and stable. One end of the spring 65 is in contact with the inner wall of the slider 6, and the other end of the spring 65 is in contact with the outer wall of the sliding groove 31, enabling the spring 65 to fully exert its elastic function during operation. When manually pinching the convex block 61, the slider 6 slides in the fixed block 3. At this time, the spring 65 is compressed and stores energy. Once the convex block 61 is released, the spring 65 quickly releases energy and pushes the slider 6 to reset, and the bolt 62 is inserted into the positioning hole 7 again to fix the mounting seat 2, which not only improves the convenience of operation but also increases the reliability and durability of the device.

[0039] The working principle of the present utility model is as follows: When the device needs to be used, only place the device main body 1 on the surface of the object to be measured and observe whether the bubble level 4 is in a horizontal state. If an object at different angles needs to be measured, manually pinch the two groups of convex blocks 61 to cause the two groups of sliders 6 to slide in the fixed block 3. At this time, the telescopic rod 64 and the spring 65 are compressed, and the bolt 62 slides out of the positioning hole 7, thereby releasing the angle limitation of the mounting seat 2. Then rotate the mounting seat 2 to adjust the bubble level 4 to an appropriate angle, and release the two groups of convex blocks 61. Under the action of the spring 65, the slider 6 resets, and the bolt 62 enters the corresponding limiting block 63 to achieve angle adjustment;

[0040] When the bubble level 4 is damaged and needs to be replaced, also manually pinch the two groups of convex blocks 61 to drive the two groups of sliders 6 and the limiting blocks 63 to slide in the fixed block 3, so that the telescopic rod 64 and the spring 65 are compressed, and the bolt 62 slides out of the positioning hole 7. After releasing the limitation of the mounting seat 2, take out the entire mounting seat 2, and then install the new bubble level 4 and related components such as the mounting seat 2 into the device main body 1 to achieve rapid replacement.

[0041] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
