TECHNICAL FIELD
[0001] The utility model relates to stage car safety protection technical field, especially a stage car aluminum alloy fence. BACKGROUND
[0002] As a flexible and variable performance and activity site, stage car is widely used in various commercial performances, artistic activities and propaganda display scenes. As a key facility to protect the safety of performers and audience, the firmness of its installation and the rationality and convenience of its connecting structure are crucial.
[0003] According to the search, the Chinese patent with publication number CN215055987U discloses a fence device including a plurality of columns and a plurality of fence assemblies. Each fence assembly includes an outer frame and a plurality of fence pipes vertically and parallelly distributed at a preset interval within the outer frame. Between two adjacent columns, there is one fence assembly. One of the fence assemblies is selected as a fence door, one side of the fence door is connected to the first column via a shaft, and the other side of the fence door is connected to the second column via a connecting assembly that can close the fence door. The other fence assemblies are fixed fence assemblies, which are fixedly connected to the columns. The surfaces formed by the plurality of fence pipes and the outer frame form a partition surface to partition the required partition area. After the fence assemblies are disassembled, they are more convenient for producers and users to store and transport. In addition, one of the fence assemblies is selected as a fence door, and the fence door is rotated to open or partition the area, so that the layout area can be flexibly changed.
[0004] However, based on the comprehensive study of the prior art, it is found that most of the current stage car aluminum alloy fences have deficiencies in installation firmness. The connection method used by some fences is relatively complex. Although complex connecting pieces are designed to try to enhance stability, the actual effect is not good. These complex connecting pieces are composed of multiple fine parts, which need to be accurately aligned during installation, and the assembly steps between the parts are complicated. Not only does it require installation personnel to have certain professional skills, but also it needs to use various special tools, which greatly increases the installation difficulty and time cost. Moreover, during actual use, due to the large number of parts, parts are easily lost or damaged. Once a part is damaged, the stability of the entire connecting structure will be affected, causing the fence to easily shake or even unable to be used normally. In addition, this complex connecting piece has poor adaptability when facing stage cars of different shapes and layouts, and it is difficult to flexibly adjust the angle and connection method between the fences, limiting the flexibility and convenience of the stage car aluminum alloy fence in actual application, and failing to meet the needs of diversified activity scenes.

[0030] The utility model improves a stage car aluminum alloy fence, and the technical scheme of the utility model is:
[0031] As shown in Figure 1 - Figure 6 A stage car aluminum alloy fence, comprising a stage car body 1 and a carriage floor 101 on the stage car body 1, a plurality of fence frames 2 are arranged on the inner bottom surface of the carriage floor 101. Four groups of fence feet are arranged on the bottom of the fence frame 2 on both sides; the positioning groove 102 is opened on the inner bottom surface of the carriage floor 101. And the positioning groove 102 corresponds to the fence foot above and below; the fence foot adopts a split structure, each group of fence feet comprises a support foot 201 fixed at the bottom of the fence frame 2 and a fixed sleeve 3 arranged at the edge of the carriage floor 101, the bottom of the support foot 201 is inserted into the mounting groove 301 opened at the top of the corresponding fixed sleeve 3, for temporarily fixing the fence frame 2 at the edge of the carriage floor 101, at this time the top of the fixed sleeve 3 is flush with the bottom surface of the carriage floor 101; further comprising an aluminum alloy connecting piece detachably arranged between the vertical rods of two adjacent fence frames 2.
[0032] As Figure 1 and Figure 2 shown, in an embodiment, the bottom of the fixing sleeve 3 is provided with a welding block 302, which is fixed in the corresponding positioning groove 102 on the carriage floor 101. The cross section of the mounting groove 301 is a tapered groove, the supporting leg 201 is made of elastic rubber material, and the supporting leg 201 has a tapered structure that is matched with the size of the inside of the mounting groove 301. By inserting the tapered supporting leg 201 with elasticity into the corresponding tapered mounting groove 301, the multiple stage car bodies 1 can be quickly connected and installed at the top edge of the carriage floor 101. When the elastic supporting leg 201 is pressed into the inside of the corresponding mounting groove 301, it is fixed on the fixing sleeve 3 through its own elastic pressure, which strengthens the fixing effect of the multiple fence frames 2 on the carriage floor 101, making the fence frame 2 more stable and less likely to loosen, and improving the safety of the stage car aluminum fence in use.
[0033] As Figure 3 and Figure 4 shown, in an embodiment, the aluminum alloy connecting piece includes a limiting baffle 4 arranged in parallel on both sides of the vertical rod of the adjacent fence frame 2. Threaded holes 401 are symmetrically provided at both ends of the two limiting baffles 4, and fixed bolts 402 are screwed into the corresponding two threaded holes 401 on the outside of the two limiting baffles 4. By providing such an aluminum alloy connecting piece, the adjacent two fence frames 2 can be temporarily fixed, and the aluminum alloy connecting piece can be used to screw the adjacent two fence frames 2 at any height position on the vertical rod of the fence frame 2. The connection method is detachable, the connection method is free, the structure is simple, the operation is convenient, and the fence frame 2 can be installed and disassembled according to the actual use demand, improving the flexibility of use.
[0034] In an embodiment, the fixing sleeve 3 is arranged in groups of four at equal intervals at the top edge of the carriage floor 101. By arranging the fixing sleeve 3 in groups of four at equal intervals, the installation of the fence frame 2 on the carriage floor 101 is more uniform and stable, ensuring the balance of the fence frame 2 when it is fixed on the carriage floor 101, and further improving the stability and safety of the stage car aluminum fence as a whole.
[0035] As Figure 1 and Figure 3As shown, in an embodiment, the fence frame 2 is welded by combining aluminum alloy pipes and rectangular pipes, and the upper corners of the fence frame 2 are processed by arc bending. By combining aluminum alloy pipes and rectangular pipes, the fence frame 2 has the characteristics of light weight and corrosion resistance of aluminum alloy material, and the strength and stability of the structure are enhanced by the rectangular pipes. At the same time, the upper corners of the fence frame 2 are processed by arc bending, avoiding sharp corners and reducing the risk of injury to personnel during use, improving the safety and comfort of use.
[0036] The working principle and use process of the utility model are as follows: when installing the aluminum alloy fence of the stage vehicle, the supporting leg 201 at the bottom of the fence frame 2 is aligned with the mounting groove 301 at the top of the fixing sleeve 3 at the edge of the vehicle compartment bottom plate 101. Since the supporting leg 201 has a tapered structure with elasticity, it can be inserted into the mounting groove 301 to temporarily fix the fence frame 2 on the vehicle compartment bottom plate 101. When two adjacent fence frames 2 need to be connected, the limiting baffle 4 of the aluminum alloy connecting piece is placed parallel on both sides of the vertical rod of the adjacent fence frame 2, and the two limiting baffles 4 are fixed by the fixing bolt 402 passing through the threaded hole 401, so that the two adjacent fence frames 2 are temporarily fixed together. When disassembling, only the fixing bolt 402 needs to be unscrewed, the aluminum alloy connecting piece is removed, and then the supporting leg 201 at the bottom of the fence frame 2 is pulled out of the mounting groove 301 of the fixing sleeve 3.
