Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a waterproof and dustproof protective cover for a field surveying instrument. Background Technology

[0002] Field surveying instruments are used for field surveying operations, with Global Navigation Satellite Systems (GNSS), remote sensing, and Geographic Information Systems (GIS) as their core technologies. They are indispensable in geological exploration, topographic surveying, and preliminary surveying for engineering construction. With technological advancements, they have evolved from traditional, simple tools to high-precision, intelligent, and portable instruments, capable of adapting to complex field environments and facilitating the efficient and accurate acquisition of geospatial data.

[0003] Utility model patent application number CN202122598126.1 discloses a drop-proof high-precision RTK measuring instrument. This instrument includes an RTK measuring body and a measuring rod. The measuring rod includes a main rod and a movable rod, with an automatic lifting assembly on the main rod. The RTK measuring body includes a housing, a cover, a power supply, an RTK motherboard, a control panel, and a free-fall sensor. The housing has multiple elongated slots, each equipped with a pop-out protective device. This utility model, by incorporating the automatic lifting assembly, can quickly configure the RTK measuring instrument to different heights according to measurement needs, allowing it to reach the optimal signal receiving position. The free-fall sensor detects whether the RTK measuring instrument has fallen. Upon a fall, the protective device automatically pops out, protecting the RTK measuring instrument and preventing damage from accidental drops. Furthermore, the spring protection device is reusable, saving costs.

[0004] Although this drop-proof high-precision RTK surveying instrument has drop protection, the following problems still exist in practical use: The device lacks a protective structure for the instrument. During field surveying operations, when users travel from one survey point to an adjacent point, the distance is usually short, and the instrument is typically carried handheld without being stored away. However, the field environment is complex and varied, with numerous obstacles such as branches and bushes, making the instrument highly susceptible to collisions during transport. Furthermore, water stains, dust, and other pollutants easily adhere to the instrument, affecting its normal operation and potentially causing damage, thus impacting the continuity and accuracy of surveying work. Therefore, we propose a waterproof and dustproof protective cover for the field surveying instrument. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0038] This embodiment provides a technical solution:

[0039] Please see Figures 1-5As shown, a waterproof and dustproof protective cover for a field surveying instrument includes a surveying instrument 1 and a handheld rod 2 fixed to the bottom of the surveying instrument 1. It also includes a fixing component 3, detachably mounted on the top of the outer wall of the handheld rod 2; two symmetrical mounting plates 30, with the handheld rod 2 passing through the connection center of the two mounting plates 30; each mounting plate 30 has a through mounting groove 301 on its top, and a through fixing groove 300 on one side of each mounting groove 301; a guide rod 34 is fixed to one side wall of each mounting groove 301, and a spring 35 is sleeved on the outside of the guide rod 34; a slider 31 is also slidably mounted inside the mounting groove 301, and a sliding hole 310 is opened on one side wall of the slider 31 to slidably connect with the guide rod 34; a limiting rod 33 is fixed to the side wall of the slider 31 away from the guide rod 34, and the limiting rod 33 passes into the fixing groove 300.

[0040] Through the above-mentioned setup, the mounting plate 30, guide rod 34, spring 35, slider 31 and limit rod 33 in the fixing component 3 interact with the fixing block 40 at the bottom of the protective cover 4, realizing the rapid installation and removal of the protective cover, effectively resisting the damage of the field environment to the surveying instrument, and ensuring the safety of the instrument.

[0041] In this embodiment, the mounting plate 30 has a semi-circular cross-sectional shape and is made of stainless steel. The semi-circular stainless steel material of the mounting plate 30 facilitates the installation of the cylindrical protective cover 4, providing all-round protection when the handheld surveying instrument is moved; the stainless steel material has good wear resistance and corrosion resistance, and can be used for a long time in harsh environments, ensuring the structural strength and stability of the fixing component 3, thereby ensuring the reliability of the installation of the protective cover 4.

[0042] In this embodiment, a semi-tube 36 is fixed to the bottom of each mounting plate 30. The semi-tube 36 is clamped to the outer wall of the handheld rod 2. Two symmetrical connecting plates 37 are fixed to the outer wall of the semi-tube 36. Two connecting bolts 39 are inserted between adjacent connecting plates 37 on the two semi-tubes 36, and nuts 390 are threaded to the ends of the connecting bolts 39. The semi-tube 36 is clamped to the handheld rod 2, and the fixing component 3 is tightly connected to the handheld rod 2 by the fastening of the connecting plates 37, connecting bolts 39, and nuts 390, preventing loosening during use and ensuring that the protective cover 4 can continuously and stably perform its protective function. At the same time, this design makes it easy to assemble and disassemble the fixing component 3.

[0043] In this embodiment, the mounting plate 30, the half-tube 36, and the connecting plate 37 are integrally formed, and the cross-sectional shape of the half-tube 36 is arc-shaped. This integrally formed structure increases the reliability of the connection between the mounting plate 30, the half-tube 36, and the connecting plate 37, thereby enhancing the overall structural strength and rigidity. The arc-shaped half-tube 36 better conforms to the handgrip 2, reducing stress concentration and effectively preventing component detachment or damage during complex field operations, thus improving the durability and reliability of the protective cover system.

[0044] In this embodiment, a hook 38 is tightly welded to the arc-shaped outer wall of one of the semi-tube bodies 36, and the overall shape of the hook 38 is J-shaped. The J-shaped hook 38 provides an additional way to carry the surveying instrument. When the field workers' hands are busy, they can hang the surveying tools on the hook 38 to free their hands; at the same time, the hook 38 also facilitates the hanging of the rope 43 to place the protective cover 4 during surveying.

[0045] In this embodiment, the spring 35 is in an extended state, with both ends of the spring 35 abutting against the inner wall of the mounting groove 301 and the slider 31, respectively. The extended spring 35 abutting against the inner wall of the mounting groove 301 and the slider 31 provides a continuous pushing force to the limiting rod 33. When installing the protective cover 4, the elastic force of the spring 35 allows the limiting rod 33 to be stably inserted into the limiting hole 400 of the fixing block 40, achieving stable locking; during disassembly, only the spring force needs to be overcome to move the slider 31, making the operation simple.

[0046] Please see Figure 2 As shown, the protective cover 4 has an open bottom and is installed on the outside of the surveying instrument 1 to protect the surveying instrument 1; two symmetrical fixing blocks 40 are fixed at the bottom of the protective cover 4 and the fixing blocks 40 are inserted into the fixing groove 300; the outer wall of the fixing block 40 is provided with a limiting hole 400, and the limiting rod 33 is inserted into the limiting hole 400 to restrict the fixing block 40 within the fixing groove 300.

[0047] With the above settings, the protective cover 4 is reliably and securely installed on the outside of the surveying instrument 1, which can effectively protect the surveying instrument 1.

[0048] In this embodiment, two positioning slots 302 are formed on the top of each mounting plate 30; two positioning blocks 41 are fixed to the bottom of the protective cover 4, and the positioning blocks 41 are inserted into the corresponding positioning slots 302. When installing the protective cover 4, this design can guide the fixing blocks 40 to be inserted into the fixing slots 300, avoid misalignment, and improve installation efficiency; at the same time, it enhances the stability of the protective cover 4 after installation, prevents it from shifting during use, and ensures the protective effect.

[0049] In this embodiment, a protrusion 42 is tightly bonded to the center of the top of the protective cover 4, and a hanging rope 43 is attached to the protrusion 42. The hanging rope 43 can be hung on the waist of the operator or on the hook 38 for easy carrying when moving in the field; the firm connection between the protrusion 42 and the hanging rope 43 ensures that the surveying instrument will not fall off accidentally during carrying.

[0050] In this embodiment, the protective cover 4, the fixing block 40 and the positioning block 41 are integrally formed, and the protective cover 4 is transparent; the integrally formed structure improves the overall strength of the protective cover 4 and reduces the risk of parts falling off; the transparent design allows operators to clearly observe the status of the surveying instrument without disassembling the protective cover 4.

[0051] In this embodiment, each slider 31 has a lever 32 fixed to its bottom, and the lever 32 is fixedly connected to the bottom of the slider 31 by bolts. The lever 32 at the bottom of the slider 31, fixedly connected to the slider 31 by bolts, provides a point of leverage for operating the slider 31. When installing and removing the protective cover 4, the operator can easily move the slider 31 by moving the lever 32, which is more labor-saving and convenient than directly operating the slider 31, thus improving the user's operating experience.

[0052] In practical use, firstly, the user clamps the two half-tubes 36 of the fixing component 3 onto the outer wall of the handheld rod 2, and tightens them with the connecting bolts 39 and nuts 390 on the connecting plate 37, so that the fixing component 3 is securely installed at the top of the handheld rod 2; then, the user moves the lever 32 at the bottom of the slider 31, so that the slider 31 slides along the guide rod 34 in the mounting groove 301, driving the limiting rod 33 to disengage from the fixing groove 300, while the slider 31 compresses the spring 35; then, the user aligns the fixing block 40 at the bottom of the protective cover 4 with the fixing groove 300 on the mounting plate 30 and inserts it; next, the user releases the lever 32, and under the action of the spring 35's extension force, the slider 31 returns to its original position, the limiting rod 33 inserts into the limiting hole 400 of the fixing block 40, and restricts the fixing block 40 within the fixing groove 300, thus completing the installation of the protective cover 4.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
