Description

Technical Field

[0001] The invention relates to a combined ground pile, belonging to the technical field of outdoor equipment. Background Art

[0002] Tents are widely used in tourism, field training and various disaster relief occasions. When setting up tents for field activities, the edges of the tents need to be fixed to the ground through tent stakes. Tent stakes are accessories used to fix tents. They are 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 stakes are difficult to embed directly into the ground in complex frozen soil environments, and there is a problem that they cannot be used. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a combined ground pile which is drilled into the ground after being disassembled.

[0004] In order to achieve the above-mentioned purpose, the technical solution proposed in the present invention is: a combined ground pile, including an inner assembly and an outer cutting piece, the inner assembly includes a pile rod and a spiral blade arranged on the pile rod, the outer cutting piece is spiral-shaped, the outer cutting piece is sleeved on the pile rod and cooperates with the spiral blade thread.

[0005] A further design of the above technical solution is that the thread profiles of the spiral blades on the external cutting member and the internal assembly member are both rectangular.

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

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

[0008] One end of the outer cutting piece 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 cone tip.

[0010] Compared with the prior art, the present invention has the following advantages: The ground piles of the present invention can be used as conventional ground piles after being assembled; for complex frozen soil environments, the inner assembly parts and the outer cutting parts can be disassembled, and the outer cutting parts can be connected to drilling tools such as drilling rigs. Since the outer cutting parts adopt a spiral structure, they can be used in conjunction with drilling rigs to drill holes in the frozen ground, and then the inner assembly parts and the outer cutting parts can be combined and nailed into the drilled holes as ground piles.

[0011] The combined ground pile of the present invention does not need to carry additional drilling bits when carrying out field activities on frozen ground, is easy to use, has a simple structure, is easy to assemble, and can be applied to many relatively complex land conditions.

[0013] In the figure: 1-inner assembly part, 11-pile rod, 12-spiral blade, 13-pile head, 14-cone tip, 2-external cutting part, 21-protrusion. DETAILED DESCRIPTION

[0014] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0015] like Figure 1 As shown, a combined ground pile of this embodiment includes an inner assembly part 1 and an outer cutting part 2, combined with Figure 2 As shown, the inner assembly 1 includes a pile rod 11 and a spiral blade 12 disposed on the pile rod 11, and the spiral blade 12 has a rectangular thread profile.

[0016] Combination Figure 3 As shown, the outer cutting member 2 is spiral, and the thread profile of the outer cutting member 2 is also rectangular, and the thread structure of the outer cutting member 2 matches that of the spiral blade 12. Therefore, the outer cutting member 2 can be screwed into the inner assembly member 1, thereby matching with the thread of the spiral blade 12, and is sleeved on the pile rod 11 to be used as a conventional ground pile. When drilling is required, the inner assembly member 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 ground pile.

[0017] In this embodiment, the thread pitch of the external cutting member 2 is the same as that of the spiral blade 12, and the sum of the thread thickness of the external cutting member 2 and the spiral blade 12 matches the pitch, so after the combination, the pile body of the ground pile is cylindrical; in this embodiment, the thread thickness of the external cutting member 2 is 1.5-2.5 times the thread thickness of the spiral blade 12, so that the thread thickness of the external cutting member 2 is relatively large and has sufficient strength for drilling holes in frozen ground.

[0018] The inner assembly 1 of this embodiment can be used alone as a ground pile, and the effect is similar to that of the combined ground pile. Embodiment 2

[0019] The combined pile structure of this embodiment is basically the same as that of the first embodiment, except that Figure 4 and Figure 5 As shown, one end of the outer cutting member 2 of this embodiment is provided with three cross fixing protrusions 21 for connecting with a drilling machine, so as to facilitate connection with a drilling machine or other machine for drilling.

[0020] In this embodiment, a pile head 13 is provided at one end of the inner assembly 1 to facilitate driving the pile into the ground, and a cone tip 14 is provided at the other end to facilitate drilling into the ground to reduce resistance.

[0021] The technical solutions of the present invention are not limited to the above-mentioned embodiments, and any technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present invention.
