[0034] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] The following describes the specific implementation of the present utility model in detail with specific embodiments:

[0036] As Figures 1-5 shown, a distance measurement and marking device at the top of a building mainly includes a tee pipe 1, a support rod 2, a cross bar 3, and a vertical rod 4. The lower part of the tee pipe 1 is installed on the support rod 2, and the cross bars 3 are respectively installed on the left and right. The vertical rod 4 is sleeved on the cross bar 3;

[0037] The paintbrush 5 and the cone pen 6 are respectively installed on the vertical rod 4;

[0038] As Figures 4-5 shown, the support rod 2 is installed on the telescopic cylinder 8, and the telescopic cylinder 8 is installed on the chassis 7.

[0039] The top of the support rod 2 has external threads, and the bottom has internal threads. The threads are matched, and multiple support rods 2 can be connected in series end to end by threads to increase the length and meet various height requirements, so that the paintbrush 5 basically touches the top of the building;

[0040] The side of the support rod 2 has a groove for fixing a wrench, so as to tighten the thread and prevent rotation.

[0041] As Figure 2 shown, the chassis 7 is triangular as a whole, and there are universal wheels 71 at the bottom, which can be pushed in any direction or rotated in place;

[0042] The center of the chassis 7 has external threads, and the external threads are matched with the internal threads of the support rod 2;

[0043] The center of the chassis 7 has an external thread and is also fixed with the telescopic cylinder 8. The telescopic cylinder 8 is composed of three parts: an inner core 81, an outer shell 82, and a pressure rod 83.

[0044] There is also a vertical block 72 on the chassis 7 for fixing the pressure rod 83. The pressure rod 83 is fixed on the vertical block and can swing up and down.

[0045] As Figures 2-3 shown, the top of the inner core 81 has a thread and the side has a protrusion. The center of the outer shell has a groove. The protrusion and the groove cooperate, enabling the inner core 81 to move up and down relative to the outer shell 82 and preventing rotation.

[0046] As Figure 3 shown, the side of the outer shell 82 has a through rectangular long hole for placing the pressure rod 83. The pressure rod 83 is tangent to the bottom of the inner core 81. Pressing the pressure rod 83 up and down by hand or foot drives the inner core 81 to move up and down, thereby enabling fine adjustment of the height of the paintbrush 5.

[0047] As Figures 4-5 shown, the bottom pipe of the T-shaped pipe 1 has an internal thread. The internal thread cooperates with the external thread of the support rod 2 and is tightened on the support rod 2. It is installed on the chassis 7 through the telescopic cylinder 8.

[0048] The side pipe of the T-shaped pipe 1 also has an internal thread. The cross bar 3 has scales on it and internal and external threads at both ends respectively. Moreover, the internal thread on the side of the T-shaped pipe 1 matches the external thread of the cross bar 3, and the external thread of the cross bar 3 also matches the internal thread of the cross bar 3. Multiple cross bars can be used in extension to meet different spacings.

[0049] The vertical rod 4 is sleeved on the cross bar 3 and is tightened by a quick-release nut to prevent rotation or shaking.

[0050] There is also a pen slot on the vertical rod 4. The pen slot has a compression spring 92, and the bottom of the compression spring 92 is fixed by a pin to prevent it from falling off.

[0051] The pen slot on the vertical rod 4 can place the paintbrush 5 and the taper pen 6, and a pre-tightening force can be formed through the compression spring 92 to better mark the spacing.

[0052] The vertical rod 4 can cooperate with the scales on the cross bar 3 to adjust the spacing between the paintbrush 5 and the taper pen 6 left and right, thereby meeting the requirements of different spacings.

[0053] When making the spacing measurement marks, the taper pen 6 is placed at the starting point, the spacing is adjusted, and the rotary chassis 7 is pushed so that the paintbrush 5 reaches the appropriate position. At this time, it does not fully contact the top. Press the pressure rod 83 with the hand or foot to extend the telescopic cylinder 8, thereby driving the paintbrush 5 to contact the top. A slight shake can complete the marking. Continuing in this way can achieve the spacing measurement and marking of the building top.

[0054] The above describes the preferred embodiments of this patent in detail. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent. Any modifications, equivalent replacements, improvements, deletions, straight-to-curved changes, etc. made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
