Description

Technical Field

[0001] The utility model relates to the technical field of counterweight bases, in particular to a gravity base. Background Art

[0002] Gravity bases are commonly used in products that require a counterweight base, such as tents, umbrellas, sheds and racks, to increase the weight of the product to improve the stability of the product when placed. Existing counterweight bases generally have a relatively fixed structural mass and cannot be easily adjusted for different counterweight requirements, and are not practical. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a gravity base, which solves the problem that the existing gravity base is not practical.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a gravity base, including a base body, the base body includes at least two bottom frames, the bottom frames are provided with an openable accommodating cavity to store counterweight blocks, and adjacent bottom frames are detachably connected by a connecting structure.

[0005] Furthermore, the connection structure includes a mounting edge arranged on the side of the bottom frame. When adjacent bottom frames are connected, the mounting edges on the adjacent bottom frames overlap and are penetrated by bolts to lock the two relative to each other.

[0006] By adopting the above technical solution and setting the installation edge, it is convenient to assemble the two floor frames by passing the bolts through the installation edge.

[0007] Furthermore, at least two accommodating cavities are provided on the bottom frame, and openings communicating with the accommodating cavities are provided on the bottom frame, and the openings are covered with a cover plate.

[0008] By adopting the above technical solution and setting a plurality of accommodating cavities, it is possible to add a counterweight block in the accommodating cavity according to different counterweight requirements, so as to change the weight of the entire bottom frame in a standard manner.

[0009] Furthermore, the bottom frame is provided with an assembly structure at the periphery of the opening, and the cover plate is provided with an avoidance gap for avoiding the assembly structure.

[0010] By adopting the above technical solution, the assembly structure facilitates the connection between the base body and external products such as tents or umbrella sheds, and avoids the influence of the gap on the connection and combination of the base body and the product.

[0011] Furthermore, the side of the bottom frame is provided with an extension piece, and when adjacent bottom frames are connected, adjacent extension pieces are arranged in a staggered manner.

[0012] By adopting the above technical solution, the staggered extension pieces can be used to offset each other in the horizontal direction when connecting two adjacent bottom frames, thereby improving the connection strength between the two. At the same time, the extension pieces extending out of the sides of the bottom frames also provide installation space for the assembly structure.

[0013] Furthermore, the assembly structure is also arranged on the extension piece.

[0014] By adopting the above technical solution, the assembly body is distributed on the extension part, so that multiple assembly structures can evenly distribute the base body. When the tent light product is connected to the base body through the assembly structure, the force exerted by the product on the base body can be evenly dispersed to the base body through the evenly distributed assembly structure, thereby improving the connection stability between the two.

[0015] Furthermore, an extension ring is provided at the bottom of the cover plate, and a clearance fit is formed between the outer wall openings of the extension ring.

[0016] By adopting the above technical solution, the clearance between the extension ring and the opening is matched, so that the sealing degree and stability of the connection between the cover plate and the opening can be improved.

[0017] Furthermore, the connection mechanism includes a buckle and a slot, and one of the adjacent bottom frames is provided with a buckle, and the other is provided with a slot that cooperates with the buckle.

[0018] By adopting the above technical solution, the buckle and the slot are connected to each other, which facilitates the convenient disassembly and assembly between adjacent bottom frames.

[0019] Furthermore, a ventilation hole is provided at the bottom of the bottom shell.

[0020] Furthermore, the base may be provided with removable rollers.

[0021] By adopting the above technical solution and setting the roller, it is convenient for the base body to be connected with the product, so that the entire product can be easily moved, and at the same time, the base body can also be easily moved through the roller.

[0022] Compared with the prior art, the advantages of the utility model are:

[0023] 1. In the utility model, an openable accommodating cavity is provided on the bottom frame, and a counterweight block is added to the accommodating cavity, so that the weight of the bottom frame can be changed. A plurality of bottom frames are detachably connected through a connecting structure, so that the overall weight of the base body can be conveniently changed to meet the counterweight requirements of different products.

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 and 2 The gravity base includes a base body, which includes at least two bottom frames 100. The bottom frames 100 are provided with an openable accommodating cavity 110 for storing counterweights 101. In this way, the weight of a single bottom frame 100 can be changed by increasing the number of counterweights 101 in the accommodating cavity 110. Adjacent bottom frames 100 are detachably connected via a connecting structure to conveniently change the overall weight of the base body to meet the counterweight requirements of different products.

[0034] In this embodiment, refer to Figure 2 The shape of the bottom frame 100 can be a ring or square structure. Taking the rectangular bottom frame 100 as an example, its square structure facilitates the splicing and combination between adjacent bottom frames 100.

[0035] In this embodiment, the connection structure includes a mounting edge 120 arranged on the side of the base frame 100, and a through hole is opened on the mounting edge 120. When adjacent base frames 100 are connected, the mounting edges 120 on the two base frames 100 overlap, and then the two are locked relative to each other after bolts penetrate the through holes, thereby realizing the connection and fixation between multiple base frames 100.

[0036] In the present embodiment, one accommodating cavity 110 can be formed on a single base frame 100, or multiple accommodating cavities 110 can be formed. When there are multiple accommodating cavities 110, the interior of the base frame 100 can be divided by a partition. An opening connected to the accommodating cavity 110 is formed at the upper end of the base frame 100 to facilitate adding a counterweight 101 into the accommodating cavity 110 through the opening. The opening is covered by a cover plate 200 to close the accommodating cavity 110.

[0037] In this embodiment, in order to facilitate the connection between the bottom frame 100 and the product, such as a tent or a shed, an assembly structure 140 is also provided on the bottom frame 100. The specific assembly structure 140 may be a common structure including screw holes, studs, etc. As long as it is convenient for connection with the product, the assembly structure may also be a connecting belt, and the gravity base may be bound to the product by using the connecting belt, which will not be elaborated here.

[0038] In this embodiment, in order to avoid affecting the connection between the bottom frame 100 and the product after the cover plate 200 and the bottom frame 100 are combined, an avoidance gap 210 is provided on the corresponding cover plate 200, and the assembly structure 140 is exposed by the avoidance gap 210 to facilitate connection with the product.

[0039] In this embodiment, the cross-section of the cover plate 200 can be larger than the size of the opening, and then the bottom of the cover plate 200 is set to an extension ring 220 that matches the clearance of the opening size, and the extension ring 220 is inserted into the opening to close the opening.

[0040] In this embodiment, refer to Figure 2 and 3 In order to facilitate the uniform distribution of the assembly structure 140 (hereinafter referred to as the screw hole) on the bottom frame 100, so as to evenly distribute the connection force points between the gravity base and the product to the entire gravity base, an extension piece 130 is provided on the side of the bottom frame 100, and the extension piece 130 protrudes from the side of the bottom frame 100. When the two bottom plates are connected, the two extension pieces 130 are staggered, and the screw holes can be provided on the extension edge and the periphery of the bottom frame 100. (Refer to Figure 3 ), four screw holes can be set in this way, two screw holes are set on the two extension pieces 130, and the other two screw holes are respectively set on the peripheries of the two bottom frames 100, so that the four screw holes form a diamond structure, and the corresponding avoidance gaps 210 of the cover plate 200 are also surrounded to form a diamond shape. Through the above arrangement, the connection force between the product and the gravity base can be effectively dispersed evenly on the entire gravity base. At the same time, since the extension pieces 130 are staggered, the two bottom frames 100 cannot move in the horizontal direction due to the restriction of the staggered extension pieces 130, and the connection strength between the two bottom frames 100 in this direction can also be improved.

[0041] In this embodiment, as another embodiment of the connection structure, the connection mechanism can also be a slot and buckle structure. By setting corresponding buckles and slots on the two bottom frames 100, quick combination and convenient separation between the two bottom frames 100 can be achieved. Of course, its connection structure can also be bolt fastening or other detachable connection methods, which will not be described in detail here.

[0042] Based on the above embodiments, the counterweight 101 may be gravel, sand or other materials with a certain weight.

[0043] In this embodiment, in order to facilitate the movement of the gravity base itself and the movement of the entire product after the gravity base is connected to the product, a roller 300 can be set at the bottom of the bottom frame 100 to facilitate the movement of the corresponding product and the gravity base itself.

[0044] Preferably, a vent is provided at the bottom of the bottom frame 100 to prevent rainwater from accumulating in the accommodating cavity 110 when water enters the accommodating cavity 110 .

[0045] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
