Description

TECHNICAL FIELD

[0001] The present application relates to a combined ground pile, belonging to the technical field of outdoor equipment. BACKGROUND

[0002] Tents are widely used in tourism, field training and various disaster relief situations. When a tent needs to be set up for field activities, the edges of the tent need to be fixed to the ground through tent ground piles. Tent ground piles are accessories used to fix tents, usually made of metal, plastic or wood. Their main function is to firmly fix the tent to the ground to prevent the tent from being blown away or moved by the wind. However, the existing ordinary tent ground piles have difficulty in directly embedding into the ground in complex permafrost environments, resulting in the problem of being unable to use. SUMMARY

[0003] In order to solve the problems in the prior art, the present application provides a combined ground pile which can drill holes in the ground after being disassembled.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the present application is as follows: a combined ground pile, comprising an inner assembly and an outer cutting member. The inner assembly comprises a pile shaft and a spiral blade arranged on the pile shaft. The outer cutting member is in a spiral shape, and is sleeved on the pile shaft and threadedly matched with the spiral blade.

[0005] Further design of the above-mentioned technical solution is as follows: the thread form of the outer cutting member and the spiral blade on the inner assembly is rectangular.

[0006] The thread pitch of the outer cutting member and the spiral blade is the same, and the sum of the thread thickness of the outer cutting member and the spiral blade matches the thread pitch.

[0007] The thread thickness of the outer cutting member is 1.5-2.5 times the thread thickness of the spiral blade.

[0008] One end of the outer cutting member is provided with a protrusion for connecting with a drilling machine.

[0009] One end of the inner assembly is provided with a pile head, and the other end is provided with a tapered tip.

[0010] Compared with the prior art, the present application has the following advantages:

[0011] The ground pile of the present application can be used as a conventional ground pile after being combined. For complex permafrost environments, the inner assembly and the outer cutting member can be disassembled, and the outer cutting member is connected with a drilling tool such as a drilling machine. Since the outer cutting member adopts a spiral structure, it can be matched with the drilling machine to drill holes in the permafrost ground. Then the inner assembly and the outer cutting member are combined to be driven into the drilled hole as a ground pile.

[0012] The combined pile of the present application is convenient to use and simple in structure, and can be assembled conveniently and is applicable to many more complex land conditions without carrying additional drilling bits when field activities are carried out on frozen ground.

[0019] The present application will be described in detail below in combination with the drawings and specific embodiments. Embodiment one

[0020] As shown in the figure, the combined pile of the present application includes an inner assembly 1 and an outer cutting member 2. Figure 1 As shown in the figure, the inner assembly 1 includes a pile rod 11 and a spiral blade 12 arranged on the pile rod 11, and the thread type of the spiral blade 12 is rectangular. Figure 2 As shown in the figure, the outer cutting member 2 is spiral-shaped, and the thread type of the outer cutting member 2 is also rectangular, and the thread structure of the outer cutting member 2 and the spiral blade 12 is matched with each other, thus the outer cutting member 2 can be screwed into the inner assembly 1, thereby being threadedly matched with the spiral blade 12 and being sleeved on the pile rod 11 to be used as a conventional pile, and when drilling is needed, the inner assembly 1 and the outer cutting member 2 are disassembled, and the outer cutting member 2 can be used as a drilling tool, thereby enhancing the applicability of the combined pile.

[0021] Figure 3

[0022] ​​​​​In the embodiment, the outer cutting piece 2 has the same thread pitch as the helical blade 12, and the sum of the thread thicknesses of the outer cutting piece 2 and the helical blade 12 matches the thread pitch, so that after combination, the pile body of the pile is in a cylindrical shape; in the embodiment, the thread thickness of the outer cutting piece 2 is 1.5-2.5 times the thread thickness of the helical blade 12, so that the thread thickness of the outer cutting piece 2 is relatively large and has sufficient strength to drill into the frozen ground.

[0023] The inner assembly 1 of the embodiment can be used as a pile alone, and has similar effects to the combined pile. Embodiment Two

[0024] The combined pile structure of the embodiment is basically the same as that of Embodiment One, and the difference is that, as shown in Figs. Figure 4 and As shown in Figs. Figure 5 The outer cutting piece 2 of the embodiment is provided with three cross-shaped fixing protrusions 21 at one end for connecting with a drilling machine, so as to facilitate connection with machines such as drilling machines to drill.

[0025] In the embodiment, the inner assembly 1 is provided with a pile head 13 at one end, so as to facilitate driving the pile into the ground, and is provided with a tapered tip 14 at the other end, so as to facilitate drilling into the ground to reduce resistance.

[0026] The technical solutions of the present application are not limited to the above embodiments, and any technical solution obtained by equivalent replacement falls within the scope of the present application.
