Detailed Description

Example 1:

referring to fig. 1-9, a detachable, stably connected five-pointed star foot comprises a main body 1 and five legs 2 distributed on the main body 1 in a circumferential array.

The five-star foot has five support legs 2 as the name implies, and in the embodiment, as shown in fig. 1, one support leg 2 is connected with a main body 1 in a splicing manner; as shown in fig. 2, three support legs 2 are connected with the main body 1 in a splicing manner; as shown in fig. 3, the five support legs 2 are connected to the main body 1 in a splicing manner, and it should be noted here that, as shown in fig. 1, the remaining four support legs 2 and the main body 1 are all integrally formed, and similarly, the remaining four support legs 2 and the main body 1 in fig. 2 are also integrally formed. Since the connection structure between each leg 2 and the main body 1 is the same, the description will not be repeated in this embodiment, and only the connection structure between one of the legs 2 and the main body 1 will be described in this embodiment.

The specific structure is that the support leg 2 is provided with a first bulge 21, two third bulges 22 and a second cavity 23.

The first protrusion 21 extends toward one side of the main body 1 and is located above the leg 2 perpendicular to the horizontal plane. A first fixing groove 211 is formed on a side surface of the first protrusion 21 facing the main body 1, and a second fixing groove 212 is formed on a side surface of the first protrusion 21 facing the ground, that is, a second fixing groove 212 is formed on a bottom surface of the first protrusion 21, so that the first fixing groove 211 and the second fixing groove 212 are vertically connected.

Here, the first fixing groove 211 and the second fixing groove 212 are specifically matched with the metal dome 3 to realize a fixing effect, and the specific structure is that the fixing portion 31 and the elastic portion 32 are arranged on the metal dome 3, the fixing portion 31 is connected with the elastic portion 32, and an angle formed by the connection of the fixing portion 31 and the elastic portion 32 is an obtuse angle, the fixing portion 31 is embedded into the first fixing groove 211, and then the fixing effect of the fixing portion 31 and the first fixing groove 211 is realized through the fastener 4, the fastener 4 is preferably set by an automatic screw, and when the firmness of fixation between the fixing portion and the first fixing groove is ensured, the convenience in fastening is also ensured. Elastic component 32 then is located the below of second fixed slot 212, elastic component 32 is for surpassing the bottom surface of first arch 21, namely make second fixed slot 212 be located elastic component 32's movement track, when first arch 21 stretches into to first cavity in, deformation takes place for elastic component 32 atress, because the effect that blocks of second fixed slot 212, guarantee elastic component 32's life, when elastic component 32 stretches into to first through-hole, elastic component 32 resumes deformation, and offsets with the inner wall of first cavity 12, thereby realize the fixed effect of overhead kick. In this embodiment, the metal dome 3 is preferably made of iron.

The number of the third protrusions 22 is two, two third protrusions 22 are respectively disposed on two sides of the first protrusion 21, and here, it should be noted that the third protrusions 22 also extend toward one side of the main body 1, but the length of the extension is less than that of the first protrusion 21, and the third protrusions 22 do not extend to the second fixing groove 212. The length of the third protrusion 22 in this embodiment can be selected according to actual requirements. Further, the third protrusion 22 is provided with a transverse convex sharp corner, and the specific structure of the third protrusion 22 is that the third protrusion 22 includes a first inclined surface 221 and a second inclined surface 222, the first inclined surface 221 and the second inclined surface 222 form a sharp corner, and the sharp corner is provided, and the third protrusion 22 is mainly matched with the fixing cavity 13 on the main body 1, so that the torsion fracture during the impact test is improved, and the torsion resistance of the product is ensured to be far beyond the industry standard.

The second chamber 23 is located below the supporting leg 2, and is arranged away from the main body 1 relative to the first protrusion 21, a second through hole 231 communicated with the bottom surface is arranged in the second chamber 23, the second through hole 231 is vertically downward and penetrates through the whole second chamber 23, namely the second through hole 231 is communicated with the outside.

Be equipped with second arch 11, first cavity 12 and fixed chamber 13 on the main part 1, here first cavity 12 is used for cooperating with first arch 21, and second arch 11 is used for cooperating with second cavity 23, and fixed chamber 13 is used for cooperating with third arch 22, so here fixed chamber 13's quantity is two, and two fixed chamber 13 divide and establish on the both sides of first cavity 12, and first cavity 12 equals with fixed chamber 13 towards the length of stabilizer blade 2. A first through hole 121 communicated with the bottom surface is arranged in the first chamber 12, the first through hole 121 is vertically arranged downwards and penetrates through the whole first chamber 12, namely, the first through hole 121 is communicated with the outside. The fixing cavity 13 is matched with the third bulge 22, and the inside of the fixing cavity 13 is also provided with a bevel.

The second protrusion 11 is arranged close to the foot 2, i.e. the length of the second protrusion 11 from the foot 2 is smaller than the length of the first cavity 12 from the foot 2. The second protrusion 11 is provided with a plastic elastic sheet 111 and a hollow portion 112, the plastic elastic sheet 111 is located on the bottom surface of the second protrusion 11, and a portion of the plastic elastic sheet extends out of the bottom surface and is elastically connected with the bottom surface, and the hollow portion 112 is located on a movement track of the plastic elastic sheet 111. It should be noted that, except for the hollow-out portion 112 where the plastic elastic sheet 111 is located, the other positions of the second protrusion 11 are all solid. Further, the second protrusion 11 is further provided with a first guide surface 113, and the second protrusion 11 is more conveniently matched with the first cavity 12 through the arrangement of the first guide surface 113. Still be equipped with on the top of second arch 11 and step down groove 114, step down the groove and be located the movement track of elastic component 32, through the setting of groove 114 of stepping down for stabilizer blade 2 is more convenient at the dismouting in-process with main part 1, and the preferred scheme of this department is that the groove 114 part of stepping down stretches into to first cavity 12, but step down groove 114 and first through-hole 121 are for cutting off the setting, are equipped with the ladder poor promptly between the two, thereby improve the back-off fastening effect of elastic component 32. In addition, the plastic elastic sheet 111 is integrally formed with the main body 1. The integrated into one piece design for holistic processing is more convenient.
