Description

Technical Field

[0001] This utility model belongs to the field of marking device technology, specifically relating to a back cover type marking device. Background Technology

[0002] During use, existing line marking devices often experience issues such as the line getting too loose, causing knots, pressure, or breakage due to wear. In such cases, it is necessary to remove the lower cover to clean the line on the reel or replace the line. However, disassembling the existing line marking device is quite troublesome, requiring the removal of all the screws on the lower cover before replacement. Therefore, a line marking device structure that allows for convenient and quick line replacement is needed. Summary of the Invention

[0003] Purpose of the utility model: To solve the problem that the disassembly of the outer shell of the existing marking device is relatively troublesome, this utility model proposes a back cover type marking device.

[0004] Technical solution: A back-cover type marking tool, comprising a hollow marking tool body, a wire spool disposed inside the marking tool body, a powder filling cover assembly disposed at the front end of the marking tool body, and a back cover; the hollow marking tool body is composed of an upper cover assembly and a lower cover, the upper cover assembly including a mechanism for driving the wire spool to rotate; the lower cover has a hollow area in the middle, and the back cover covers the hollow area.

[0005] Furthermore, the size of the hollowed-out area is consistent with the size of the coil.

[0006] Furthermore, the spool includes a shaft that drives the spool to rotate, the upper end of which is connected to the upper cover assembly, and the lower end of which contacts the back cover.

[0007] Furthermore, it also includes a sealing ring, which is disposed on the outer edge of the back cover.

[0008] Beneficial effects: Compared with the prior art, the marking device proposed in this utility model has a split back cover design in the middle of the lower cover. If the line gets stuck, knotted or worn during use, the line can be quickly and conveniently sorted and replaced. Moreover, without affecting the overall strength, this design also makes the marking device lighter. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

[0015] In the description of this utility model, it should be understood that the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0016] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] In this utility model, "up," "down," "left," and "right" are descriptions of specific orientations in actual use based on the accompanying drawings.

[0018] like Figures 1 to 5As shown, this embodiment proposes a back-cover type marking tool, which mainly includes: an upper cover assembly 1, a wire reel 2, a powder filling cover assembly 3, a lower cover 4, a sealing ring 5, and a back cover 6. The upper cover assembly 1 and the lower cover 4 constitute the main body of the marking tool. Inside the main body of the marking tool, there is a cavity for placing the wire reel 2. The upper cover assembly 1 is provided with a component for driving the wire reel 2 to rotate. The powder filling cover assembly 3 is located at the front end of the marking tool body. The wire on the wire reel 2 passes through the powder filling cover assembly 3 and extends out of the marking tool. The lower cover 4 designed in this embodiment has a hollow area. The size of the hollow area matches the size of the wire reel 2. The purpose is to use the hollow area to quickly and conveniently organize and replace the wire on the wire reel 2. The sealing ring 5 is set along the hollow area. The back cover 6 is fixed to the lower cover 4 by a fixing screw 7. At this time, the sealing ring 5 makes the connection between the back cover 6 and the lower cover 4 sealed. Furthermore, an assembly adapted to the shaft of the spool 2 is provided on the inner surface of the back cover 6, allowing the spool 2 to rotate smoothly within the entire body of the scribing device.

[0019] The marking device proposed in this embodiment features a split back cover 6 added to the middle of the lower cover 4. If the wire gets stuck, knotted, or worn during use, the wire can be quickly and easily sorted and replaced. Moreover, this design makes the marking device lighter without affecting the overall strength.

[0020] When the marking device is used for the first time or when the internal powder level is insufficient and needs to be added, rotate the powder adding cap 90°, the latch will disengage from the marking device housing, and the entire side door mechanism will rotate outward to open.
