Description

Technical Field

[0001] This utility model relates to the field of loader display instruments, and in particular to a waterproof cover for a loader electronic scale instrument. Background Technology

[0002] A loader is a type of earthmoving machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is mainly used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil.

[0003] Existing instrument protective covers typically connect to the loader scale via a pivot, allowing the cover to be flipped and improving usability. However, due to the nature of the pivot, the side of the cover furthest from the pivot cannot be tightly fitted to the loader scale, resulting in poor protection. Furthermore, most existing protective covers are assembled using bolts and two separate housings. During installation, since the scale is installed on one side of the loader cab, the space between the scale instrument and the cab is limited, requiring the scale instrument to be disassembled before installation, making the process particularly inconvenient. Utility Model Content

[0004] One objective of this utility model is to provide a waterproof cover for a loader electronic scale instrument that at least solves any of the above-mentioned technical problems.

[0005] A further objective of this invention is to avoid the inconvenience of installing waterproof covers.

[0006] Another further objective of this invention is to improve the ease of installation of the protective cover, allowing for direct installation.

[0007] In particular, this utility model provides a waterproof cover for a loader electronic scale instrument, including a housing, the housing having a cavity with a downward opening, and slots and latches respectively provided on both sides of the housing, the slots and latches being arranged opposite to each other, and the lower part of the latches communicating with the opening;

[0008] A slot, wherein the slot is disposed at the lower part of the slot and the slot is inclined;

[0009] A insert plate, which is disposed within the slot, is used to close the downward-facing opening.

[0010] Furthermore, the upper part of the insert plate is provided with an overflow groove, one end of which passes through the slot opening.

[0011] Furthermore, the cross-sectional shape of the bayonet gradually increases from the center towards the cavity.

[0012] Furthermore, a symmetrical retaining ring is provided in the middle of the bayonet, and a spring is provided inside the retaining ring.

[0013] Furthermore, a hinged cover is provided in the slot, and the upper end of the hinged cover is hinged to the slot.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model is designed as a single unit, with the lower opening of the housing fitting over the electronic scale instrument, thus protecting the part facing the user. A buckle is located at the rear of the housing, accommodating the connection between the instrument and the vehicle body during insertion, preventing interference with the instrument's movement. An inclined insert plate with an overflow groove is located at the bottom of the housing, preventing water residue from accumulating inside the cover and thus avoiding moisture corrosion of the instrument's outer shell. In use, first remove the bottom insert plate, align the lower opening of the housing with the upper part of the instrument, and slide it over from top to bottom. After sliding, insert the insert plate to complete the process. It is convenient, quick, and easy to disassemble. Attached Figure Description

[0023] 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.

[0025] This embodiment provides a waterproof cover for a loader electronic scale instrument, including a housing 1, a slot 4, and a plate 5. The housing 1 has a downward-opening cavity. Slots 3 and bayonets 8 are respectively provided on both sides of the housing 1. The slots 3 and bayonets 8 are arranged opposite to each other, and the cross-sectional shape of the bayonets 8 gradually increases from the center towards the cavity. Figure 2 As shown in the diagram, the lower part of the bayonet 8 is connected to the opening. A symmetrical retaining ring 9 is provided in the middle of the bayonet 8. A spring 10 is provided inside the retaining ring 9. When the housing 1 is inserted from top to bottom, the retaining ring 9 is compressed by force, and the fixed connection part of the electronic scale instrument enters the buckle through the retaining ring 9 for fixation. After passing through, the retaining ring 9 is reset by the influence of the spring 10, thereby restricting the movement of the fixed connection. It should be noted that the retaining ring 9 is made of soft plastic or rubber with good toughness. The slot 4 is located in the lower part of the slot 3, and The slot 4 is inclined and passes through the housing 1; the insert plate 5 is disposed in the slot 4 and is used to close the downward-facing opening. An overflow groove 6 is provided on the upper part of the insert plate 5. One end of the overflow groove 6 passes through the opening of the slot 4. The overflow groove 6 prevents water stains or water droplets generated inside the housing 1 from remaining inside the housing 1 and drains the water inside the housing 1 through the overflow port; at the same time, a cover plate 7 is also provided on the upper part of the bayonet 8 to prevent water from entering directly from the bayonet 8.

[0026] It should be further explained that a hinged cover 2 is provided in the slot 3, and the upper end of the hinged cover 2 is hinged to the slot 3. The hinged cover 2 is easy to open and operate the covered instrument.

[0027] Working principle of this utility model:

[0028] In use, the housing 1 is fitted over the electronic scale instrument through the opening at the bottom, thus protecting the part facing the user. A buckle is located at the rear of the housing 1, which accommodates the connection between the instrument and the vehicle body during insertion, preventing interference with the instrument's movement. An inclined insert plate 5 with an overflow groove 6 is located at the bottom of the housing 1. The inclined insert plate 5 prevents water residue from accumulating inside the protective cover, thus preventing moisture from corroding the instrument's outer casing. To use, first remove the bottom insert plate 5, align the lower opening of the housing 1 with the upper part of the instrument, and slide it over from top to bottom. After sliding, insert the insert plate 5 to complete the process. It is convenient, quick, and easy to disassemble.

[0029] 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.
