[0002] When measuring on a construction site, it is necessary to use a surveying nail to mark a measurement point, and then insert the tip of the measuring ruler into the positioning hole on the nail cap and place it vertically for measurement.

[0003] Currently, the upper surface of the nail cap of the surveying nail is a convex circular curved surface, which is smooth. There is a positioning hole at the center of the circular curved surface. When the measuring ruler is inserted, the surface of the nail cap is slippery. Since the positioning hole is small, it is always difficult for the tip of the measuring ruler to quickly and accurately insert into the positioning hole. Before the surveying nail is driven into the ground, it needs to be held for a period of time, and the existing surveying nail is prone to loosen from the surveying nail device.

[0004] Therefore, a new type of surveying and mapping nail device is proposed to solve the above disadvantages. Content of the Utility Model

Specific embodiments

[0027] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0028] Please refer to Figures 1-4 As shown, in this embodiment, a new type of surveying and mapping measuring nail device is provided, including a fixed cylinder 1. The inside of the fixed cylinder 1 is elastically and slidably fitted with a guide rod 104. A sliding disc 107 is installed at the lower end of the guide rod 104, and the sliding disc 107 is slidably fitted inside the fixed cylinder 1;

[0029] A fixed sleeve 111 rotatably fitted at the upper end of the fixed cylinder 1, and the inner side wall of the fixed sleeve 111 is fitted with the upper end of the guide rod 104;

[0030] A measuring nail body 109 located inside the lower end of the fixed cylinder 1, and the upper end of the measuring nail body 109 is magnetically fitted with the lower end of the sliding disc 107.

[0031] Working principle:

[0032] First, the fixed sleeve 111 is removed from the upper end of the fixed cylinder 1. Then, the guide rod 104 is slid upward. The guide rod 104 drives the sliding disc 107 to slide upward. Then, the measuring nail body 109 is placed inside the lower end of the fixed cylinder 1. Then, the measuring nail body 109 is adsorbed by the sliding disc 107. Then, the fixed cylinder 1 is moved to the upper side of the positioning hole. Then, the guide rod 104 is released, and the guide rod 104 returns to its original position under the action of elasticity. The guide rod 104 drives the measuring nail body 109 through the sliding disc 107 to be positioned inside the positioning hole. Then, the fixed cylinder 1 can be removed.

[0033] The provided guide rod 104 enables the sliding disc 107 to drive the measuring nail body 109 to move under the action of the guide rod 104, and the measuring nail body 109 is moved inside the positioning hole through the sliding disc 107, reducing the problem of the measuring nail body 109 falling off during placement, making the process of placing the measuring nail body 109 more convenient, and improving the placement efficiency of the measuring nail body 109.

[0034] To make the sliding plate 105 of this embodiment slide more stably on one side of the fixed cylinder 1, the following structure is used for improvement, as Figures 1-4 As shown, a magnet 108 is installed at the lower end of the sliding disk 107 of this embodiment. The magnet 108 is located inside the fixed cylinder 1. The bottom of the magnet 108 is magnetically engaged with the upper end of the nail measuring body 109. A guiding hole 102 is opened at the upper end of the fixed cylinder 1. The upper end of the guiding rod 104 is slidably engaged inside the guiding hole 102. Two sliding plates 105 are installed on the outer side wall of the guiding rod 104. A spring 106 is installed between the sliding plate 105 and the side wall of the fixed cylinder 1. The spring 106 is sleeved on the periphery of the guiding rod 104. Two guiding grooves 103 are opened on the outer side wall of the fixed cylinder 1. The sliding plate 105 is slidably engaged inside the guiding groove 103.

[0035] When this embodiment is in use, first slide the sliding plate 105 upward. The sliding plate 105 slides inside the fixed cylinder 1 through the guiding groove 103. The sliding plate 105 drives the guiding rod 104 to slide inside the guiding hole 102 and compress the spring 106. One end of the guiding rod 104 drives the magnet 108 to move through the sliding disk 107. Then place the nail measuring body 109 inside the fixed cylinder 1 and adsorb the nail measuring body 109 through the magnet 108. Then drive the nail measuring body 109 to move through the fixed cylinder 1.

[0036] The provided guiding groove 103 is used to guide the sliding direction of the sliding plate 105 through the guiding groove 103, reducing the problem of the sliding plate 105 tilting during sliding and improving the stability of the sliding plate 105 during sliding. The provided guiding hole 102 enables one end of the guiding rod 104 to slide inside the fixed cylinder 1 through the guiding hole 102, improving the stability of the guiding rod 104 during sliding and making the sliding process of the guiding rod 104 more convenient.

[0037] To make the fixing of the fixing sleeve 111 of this embodiment on one side of the annular plate 110 more stable, the following structure is used for improvement, as Figures 1-4 As shown, an annular plate 110 is installed at the upper end of the fixed cylinder 1 of this embodiment. The annular plate 110 is sleeved on the periphery of the guiding rod 104. External threads are provided on the outer side wall of the annular plate 110. Internal threads are provided on the inner side wall of the fixing sleeve 111. The internal threads are in threaded engagement with the external threads. A rubber pad 101 is installed on the outer side wall of the fixed cylinder 1.

[0038] When this embodiment is in use, first rotate the fixing sleeve 111. The fixing sleeve 111 is rotated out from the outer side wall of the annular plate 110 through the internal threads and external threads, and then drive the guiding rod 104 to slide inside the fixed cylinder 1. The provided fixing sleeve 111 is used to position the guiding rod 104 inside the fixed cylinder 1 through the side wall of the fixing sleeve 111, reducing the problem of the guiding rod 104 sliding out of the fixed cylinder 1.
