[0002] Plumbing and electrical installation is a construction process in the early stage of decoration. During the plumbing and electrical construction process, because water pipes or electrical wires need to be buried in walls or the ground, it is necessary to cut grooves on the walls or the ground. Before cutting grooves, in order to ensure the accuracy of the groove positions, a marking device is usually used to mark the positions and styles of the grooves to be cut.

[0003] At present, the most commonly used marking device in the construction process is the line-laying ink fountain. However, there are still certain problems in the use of the existing line-laying ink fountain. For example, when the line-laying ink fountain is marking on the wall or the ground, the end of the ink line is not convenient to be fixed on the wall or the ground because the wall or the ground is relatively hard. In this way, one more person is required to pull the end of the ink line to complete the marking. In addition, the line-laying ink fountain needs to be manually rotated and retracted during the line-retracting process, which is cumbersome to use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: an auxiliary marking device for water and electricity installation, including a device body 1, a first movable cover 2 and a second movable cover 3 are installed above the device body 1, a handle 4 is fixed to the rear side of the device body 1, a rod sleeve 5 is fixed to the outside of the device body 1, an assembling rod 6 is connected to the rod sleeve 5, a connecting block 7 is installed at the front end of the assembling rod 6, a hook 8 is connected to the connecting block 7, and an ink line 9 is fixed to the hook 8.

[0021] Furthermore, the rod sleeve 5 is integrated with the device body 1, and a rubber pad 15 is provided inside the rod sleeve 5, and an assembling rod 6 is connected to the rubber pad 15. Through the rubber pad 15 inside the rod sleeve 5, the assembling rod 6 can be kept in a stable position during use. It should be noted here that the friction force between the assembling rod 6 and the rubber pad 15 in the rod sleeve 5 must always be greater than the pulling force of the ink line 9 on the connecting block 7 on the assembling rod 6, so that the position of the assembling rod 6 in the rod sleeve 5 will not be affected by the pulling force of the ink line 9. At the same time, the friction force between the assembling rod 6 and the rubber pad 15 can also be too large to ensure that the user can manually move the position of the assembling rod 6 inside the rod sleeve 5 more easily. The specific setting can be combined with the actual situation and is not described in detail here.

[0022] Furthermore, the assembly rod 6 is composed of a plurality of individuals, which are connected by threads, and each individual has an equal outer diameter, so that the assembly rod 6 can be disassembled and assembled, which is convenient for the storage of the marking device. Scale lines are provided on the assembly rod 6, so that the working length of the ink line 9 can be determined.

[0023] Two cavities are opened in the device body 1, corresponding to the bottom of the first movable cover 2 and the second movable cover 3 respectively. An ink-absorbing sponge 13 is arranged in the cavity below the first movable cover 2, and a winding shaft 12 is installed in the cavity below the second movable cover 3. An ink line 9 is wound around the winding shaft 12. The ink line 9 passes through the ink-absorbing sponge 13 in the cavity below the first movable cover 2 and is connected to an external hook 8.

[0024] Furthermore, the first movable cover 2 and the second movable cover 3 are embedded in the device body 1, and a magnet 14 is provided at the connection between the first movable cover 2 and the second movable cover 3 and the device body 1, which not only ensures the stability of the state of the first movable cover 2 and the second movable cover 3, but also facilitates the disassembly and assembly of the first movable cover 2 and the second movable cover 3, and facilitates the maintenance work inside the device body 1, thereby ensuring the normal use of the marking device.

[0025] Furthermore, the inner bottom surface of the cavity below the first movable cover 2 is set to be an arc shape, the lower side of the ink-absorbing sponge 13 is in contact with the inner bottom surface of the cavity, and the ink line 9 is located in the lower middle position of the cavity below the ink-absorbing sponge 13 and the first movable cover 2, which can ensure that the ink in the ink-absorbing sponge 13 is concentrated near the ink line 9, thereby ensuring the normal marking operation of the ink line 9.

[0026] The outer end of the winding shaft 12 is located in the spring box 10, and a clockwork spring 11 is installed in the spring box 10. The inner and outer ends of the clockwork spring 11 are respectively fixed on the winding shaft 12 and the spring box 10. When the ink line 9 is released, the clockwork spring 11 can apply a reverse torsional force to the winding shaft 12. In this way, when the ink line 9 is released, the ink line 9 can be automatically wound up by the clockwork spring 11, thereby improving the use efficiency of the line drawing device.

[0027] Furthermore, a detachable box cover is provided on the spring box 10 , and the box cover is threadedly connected to the spring box 10 , so as to facilitate the inspection and maintenance of the clockwork spring 11 inside the spring box 10 .

[0028] Furthermore, the assembly rod 6 is a hollow tube, and the device body 1 is made entirely of plastic, which effectively reduces the overall weight of the line drawing device and facilitates the handheld use of the line drawing device.

[0029] Specifically, when using the marking device, firstly, according to the requirements of the hydropower construction, the assembly rod 6 is assembled to a suitable length, and then the assembled assembly rod 6 is inserted into the rod sleeve 5, and the hook 8 at the front end of the ink line 9 is hung on the connecting block 7 at the front end of the assembly rod 6, so that the assembly rod 6 can control the ink line 9;

[0030] When drawing lines, the first movable cover 2 is opened to add the ink required for drawing lines to the ink-absorbing sponge 13, and then the first movable cover 2 is closed. Under the action of the magnet 14, the first movable cover 2 can be stably placed on the device body 1. The user holds the handle 4 and manually pushes the assembly rod 6 forward according to the required drawing length. The assembly rod 6 can move forward in the rod sleeve 5. As the assembly rod 6 is pushed forward, the front end of the assembly rod 6 is connected to the connecting block 7 and the hook 8, so that the ink line 9 can be pulled out of the device body 1.

[0031] When the ink line 9 is pulled out of the device body 1, the ink line 9 will be covered with ink through the ink-absorbing sponge 13. When the drawn ink line 9 reaches the required length, the user can stick the drawing device on the wall or the bottom surface, and pull the ink line 9 by hand to pop up a line on the wall or the bottom surface, thus completing the drawing work;

[0032] When drawing lines of different lengths, the length of the ink line 9 can be adjusted by moving the assembly rod 6. When the working length of the ink line 9 changes, the ink line 9 can be automatically reeled on the reel-up shaft 12 under the action of the spring 11 in the spring box 10, thereby ensuring the normal working state of the ink line 9. In addition, during the drawing process, the position of the assembly rod 6 can be adjusted because the rubber pad 15 is present in the rod sleeve 5. The rubber pad 15 can stabilize the position of the assembly rod 6. In this way, during the drawing process, it is not necessary to always control the assembly rod 6, thereby making the drawing process more convenient.

[0033] The above is the use process of the line drawing device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
