Description

Technical Field

[0001] This utility model relates to the field of engineering surveying, and in particular to a leveling point marker shell with impact resistance. Background Technology

[0002] Benchmarks, also known as level points or elevation control points, are standard markers used in surveying and engineering to indicate the elevation of a specific location. These markers are usually permanently placed on the ground or buildings to facilitate work such as elevation measurement and topographic map production.

[0003] The existing leveling point markers are made of metal and serve three purposes: first, to provide a warning; second, to facilitate locating the leveling point during work; and third, to be marked with a code. Leveling point markers are usually fixed directly to the concrete ground using positioning nails.

[0004] However, existing settlement observation points often use metal gaskets or metal covers as the components for marking and receiving leveling rods. These are expensive, heavy, and prone to corrosion when exposed for a long time. They are also susceptible to plastic deformation under construction compaction or mechanical impact, affecting the stability of the leveling rod's contact surface and the benchmark position. Some solutions use simple plastic covers or protective sleeves, but these are mostly thin-shell covers with insufficient impact resistance, anti-disassembly, and anti-loss capabilities. They also have poor visibility at night and in low-light conditions, which is not conducive to rapid positioning and operation and maintenance management. Therefore, a leveling point marker shell with impact resistance is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a leveling point marker housing with impact resistance, aiming to solve the problem of poor impact resistance in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leveling point marker housing with impact resistance, comprising a leveling point marker body, wherein the top of the leveling point marker body is fixedly connected to the housing, and a support component is provided between the leveling point marker body and the housing;

[0007] The support assembly includes a base plate and a support block. The bottom wall of the support block is fixedly connected to the top of the base plate, and the top of the support block is fixedly connected to the inner top wall of the housing. The bottom of the base plate abuts against the upper surface of the leveling point marker body.

[0008] As a further description of the above technical solution: the support block is a honeycomb block, and an elastic support strip is fixedly connected to the upper surface of the base plate.

[0009] As a further description of the above technical solution: the top of the elastic support bar abuts against the inner top wall of the outer shell, and the elastic support bar is wavy.

[0010] As a further description of the above technical solution: a positioning pin is provided in the middle of the leveling point marker body, a positioning hole is opened in the middle of the upper surface of the leveling point marker body, a bushing is fixedly connected to the inner wall of the positioning hole, and the outer wall of the positioning pin is inserted into the inner wall of the bushing.

[0011] As a further description of the above technical solution: a pressure cap is fixedly connected to the upper end of the positioning pin, a cross groove is opened on the upper surface of the pressure cap, and an annular elastic buffer layer is provided between the pressure cap and the bushing.

[0012] As a further description of the above technical solution: the bottom of the leveling point marker body is fixedly connected with radial reinforcing ribs, and the bottom of the leveling point marker body is fixedly connected with an annular reinforcing ring.

[0013] As a further description of the above technical solution: a drainage and sand guiding groove is provided at the bottom of the leveling point marker body.

[0014] As a further description of the above technical solution: the upper surface of the outer shell is provided with an marking groove, and a reflector is fixedly connected to the inner wall of the marking groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the leveling point is subjected to mechanical impact or crushing from the top, the top of the outer shell will be concave downward to press against the support block and the elastic support strip. The two absorb the impact energy through elastic deformation, and the outer shell returns to its original position after the external force is removed, thus avoiding plastic deformation.

[0017] 2. In this utility model, the leveling point marker body is made of plastic, which has the advantages of low cost, light weight and the ability to use different colors to distinguish functions compared with traditional metal materials.

[0018] 3. In this utility model, a multi-level energy dissipation channel is formed by an annular reinforcing ring, radial ribs, and an elastic buffer layer, which significantly reduces the transmission of external force peaks, protects the reference point from failure, and improves the impact resistance of the sign. The rigid bushing ensures the stability of the hole position and the concentricity of repeated clamping, reducing the deviation of the measuring ruler contact surface. The high visibility color and reflective layer enable long-distance rapid positioning, reducing the time spent finding the point and the probability of accidental stepping. The recessed marking area supports laser engraving / QR code, which facilitates digital ledger and life cycle management.

[0019] 4. In this utility model, the injection-molded plastic parts are lightweight, have low finished product cost, are corrosion-resistant and weather-resistant, and can be adapted to common positioning nails using 8 / 10 / 12mm three-type bushings, which facilitates the modification and new installation of existing points and improves the versatility of the signs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3This utility model provides an embodiment of a leveling point marker housing with impact resistance, comprising a leveling point marker body 1, a housing 2 fixedly connected to the top of the leveling point marker body 1, and a support component 3 provided between the leveling point marker body 1 and the housing 2. The support component 3 can push the body to return to its initial shape after the external force is removed, avoiding irreversible plastic deformation. The outer diameter of the leveling point marker body 1 is preferably 50-90mm, and the material is weather-resistant engineering plastic (such as PA6 / PA66+GF, PC / ABS or PP modified), containing anti-ultraviolet and anti-aging additives. Compared with traditional metal materials, it has the advantages of low cost, light weight and the ability to use different colors to distinguish functions.

[0029] Reference Figures 3-4 The support component 3 includes a base plate 301 and a support block 302. The bottom wall of the support block 302 is fixedly connected to the top of the base plate 301, and the top of the support block 302 is fixedly connected to the inner top wall of the outer shell 2. The support block 302 can support the top of the outer shell 2, making it easier for the outer shell 2 to return to its original position after being impacted by external forces. The bottom of the base plate 301 abuts against the upper surface of the leveling point marker body 1. The support block 302 is a honeycomb block, and its honeycomb holes can improve the recovery ability of the support block 302 and the buffering effect after being subjected to force. An elastic support strip 303 is fixedly connected to the upper surface of the base plate 301. The top of the elastic support strip 303 abuts against the inner top wall of the outer shell 2. The elastic support strip 303 is wavy. The support block 302 and the elastic support strip 303 are made of rubber, which is used to help the outer shell 2 return to its original position after the external force is removed, and to avoid plastic deformation.

[0030] Reference Figures 1-2 The leveling point marker body 1 has a positioning pin 5 in the middle. The positioning pin 5 has a diameter of 8 mm, 10 mm and 12 mm. The upper surface of the leveling point marker body 1 has a positioning hole 4 in the middle. The inner wall of the positioning hole 4 is fixedly connected to a bushing 8. The bushing 8 is made of metal or high hardness engineering plastic. The outer wall of the positioning pin 5 is inserted into the inner wall of the bushing 8 to make interference or clearance fit with the shank of the positioning pin 5 / bolt, reduce hole wear and ensure coaxiality. The bushing 8 is replaceable and provides three specifications of 8 mm, 10 mm and 12 mm to adapt to positioning pins 5 of different diameters.

[0031] Reference Figures 1-2 , Figure 5A pressure cap 14 is fixedly connected to the upper end of the positioning pin 5. A cross groove 15 is formed on the upper surface of the pressure cap 14, which can be replaced by a dot groove. An annular elastic buffer layer 9 is provided between the pressure cap 14 and the bushing 8. The annular elastic buffer layer 9 can be TPU / TPE / polyurethane or rubber O-rings. It abuts against the pressure cap 14 on the head of the positioning pin 5, using elastic deformation to absorb impact energy and suppress the direct transmission of stress to the reference point. Radial reinforcing ribs 11 are fixedly connected to the bottom of the leveling point marker body 1. It has an annular reinforcing ring 12 and preferably 6-10 radial reinforcing ribs 11. The rib thickness gradually changes from the center to the outside, so that it can generate controllable elastic deformation to dissipate energy when subjected to force. The bottom of the leveling point marker body 1 is provided with a water drainage and sand guiding groove 13. The water drainage and sand guiding groove 13 can prevent water / mud and sand from accumulating and affecting the fit. The upper surface of the outer shell 2 is provided with a marking groove 6. The marking groove 6 is used for printing / laser coding of text, numbers, QR codes or icons. The inner wall of the marking groove 6 is fixedly connected with a reflector 7. The setting of the reflector 7 can improve low light visibility.

[0032] The main body provides a variety of highly visible colors (such as yellow, orange, red, blue, green, white, purple, etc.) to distinguish different projects, stages or monitoring categories. The color-purpose correspondence can be agreed upon in the instruction manual or operation and maintenance manual.

[0033] Working principle: When the leveling point marker is subjected to mechanical impact or rolling from above, the top of the outer shell 2 will indent downwards to press against the support block 302 and the elastic support strip 303. The two absorb the impact energy through elastic deformation. After the external force is removed, the outer shell 2 returns to its original position to avoid plastic deformation. When the outer shell 2 is subjected to external impact, it absorbs the impact energy through elastic deformation, reducing the stress directly transmitted to the marker body. This design significantly improves the impact resistance and durability of the marker device in harsh environments such as construction rolling and external mechanical impact, while ensuring the accuracy of leveling point measurement, and reduces the risk of measurement benchmark failure caused by external force damage.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
