[0018] 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.

[0019] Please see Figure 1-2 This application proposes a construction marker according to the embodiment of the present invention, including a marker cylinder 1 and a base 2. A sliding rod 3 is vertically provided inside the marker cylinder 1. The bottom of the sliding rod 3 slides through the marker cylinder 1 and the base 2 and extends to the lower side of the base 2. A marker sponge 4 is provided at the end. A storage groove 5 is provided at the bottom of the base 2 corresponding to the marker sponge 4 for storing the marker sponge 4 when not in use. A square pressure rod 6 is provided horizontally inside the marker cylinder 1 corresponding to the top of the sliding rod 3. The two ends of the square pressure rod 6 extend to both ends and pass through the marker cylinder 1 to their outer sides. A limiting groove 7 is provided longitudinally in the marker cylinder 1 corresponding to the square pressure rod 6 to limit the movement direction of the square pressure rod 6 and ensure its smooth sliding.

[0020] Furthermore, the sliding rod 3 is fitted with a guide sleeve 8 inside the marking cylinder 1. The guide sleeve 8 has a fixing rod 9 fixed inside the marking cylinder 1 on both the left and right sides. This design can ensure that the sliding rod 3 remains stable during the up and down movement and avoids deviation.

[0021] To achieve the automatic rebound function, the square pressure rod 6 is positioned opposite the fixed rod 9, and a first spring 10 is vertically arranged between them. A guide rod 11 is longitudinally arranged on the lower side of the square pressure rod 6 corresponding to the first spring 10. The guide rod 11 passes downward through the fixed rod 9 and is slidably connected to it. The first spring 10 is sleeved on the guide rod 11. When the square pressure rod 6 is pressed down, the first spring 10 is compressed and stores elastic potential energy. When released, the first spring 10 releases energy, pushing the square pressure rod 6 upward, so that the marking sponge 4 returns to the storage slot 5.

[0022] Furthermore, a buffer structure 12 is provided at the top of the marking cylinder 1 corresponding to the square pressure rod 6. The buffer structure 12 includes a damper 13 arranged longitudinally at the top of the marking cylinder 1. A contact plate 14 is provided horizontally at one end of the damper 13 corresponding to the square pressure rod 6. A buffer plate 15 is provided laterally on the upper side of the contact plate 14. A second spring 16 is fixed vertically on the lower side of the buffer plate 15. A clearance hole 17 is provided on the contact plate 14 corresponding to the second spring 16. The bottom of the second spring 16 extends downward from the clearance hole 17. When the square pressure rod 6 moves upward, it first contacts the second spring 16, and the second spring 16 is compressed, which plays a preliminary buffering role. Then the square pressure rod 6 continues to move upward and contacts the contact plate 14. At this time, the damper 13 starts to work, further reducing the impact and preventing the marking sponge 4 from rebounding quickly and causing the marking liquid to splash.

[0023] For ease of operation, the two ends of the square pressure bar 6 located outside the marking cylinder 1 form handles 18, and each handle 18 is fitted with an anti-slip rubber sleeve 19. The anti-slip rubber sleeve 19 can increase the friction between the operator's hand and the handle 18, prevent slippage during operation, and improve the stability and comfort of operation.

[0024] Furthermore, the top of the marking sponge 4 is provided with a mounting plate 20, and the bottom of the sliding rod 3 is provided with a mounting seat 21 corresponding to the mounting plate 20. The mounting plate 20 can be installed on the mounting seat 21 by bolts. This design facilitates the replacement of the marking sponge 4. When the marking sponge 4 is worn or the marking liquid is used up, a new marking sponge 4 can be easily removed and replaced, extending the service life of the marker.

[0025] In addition, a handle 22 is fixedly provided on the top of the marking cylinder 1. The design of the handle 22 makes it easier for operators to carry and move the marker, making it more convenient to use in the construction site.

[0026] When using this construction marking device, the operator holds the handle 18 with both hands and presses down on the square pressure bar 6, causing the marking sponge 4 to extend from the storage slot 5 and contact the surface to be marked, completing the marking action. After releasing the handle 18, the first spring 10 pushes the square pressure bar 6 upward, and the marking sponge 4 returns to the storage slot 5. During the upward movement of the square pressure bar 6, the second spring 16 and the damper 13 act as a buffer to prevent the marking sponge 4 from rebounding too quickly and causing the marking liquid to splash.

[0027] In summary, this construction marking device effectively avoids splashing and waste of marking liquid while ensuring the integrity of the marking. Its rational structural design enables convenient and quick operation, improving the efficiency and quality of construction marking.
