[0002] At the present stage, high-end manufacturing is prevalent, and the requirements for the outer protection of intelligent manufacturing equipment have increased sharply. The outer protection of existing intelligent equipment is mostly a house made of non-standard sheet metal. Inside the house is a framework made of several square tubes of different lengths for support.

[0003] Existing protective sheet metal houses are basically spliced by cross connectors and steel pipes. Their convenient installation method and high-strength support strength. Due to the variety of cross connectors on the market, there are also different requirements for bolt fixation during the insertion process of steel pipes, and one end of the bolt cannot be effectively fixed externally after fixation. As a result, the bolt becomes loose after long-term use, thereby increasing the safety hazard of the house body.

[0004] Therefore, we designed a cross connector for assembling the main body framework of an outer protective sheet metal house. Content of the Utility Model

[0005] The purpose of the utility model is to propose a cross connector for assembling the main body framework of an outer protective sheet metal house to solve the problem of bolt loosening after long-term use in the prior art.

The horizontal bracket is fixedly connected to the vertical bracket by welding. A steel pipe for connecting the house body is arranged inside the horizontal bracket;

[0008] A first stopper for restricting the depth of the steel pipe is arranged inside the horizontal bracket. Auxiliary grooves for adding anti-slip objects are symmetrically opened inside the vertical bracket. Restricting clamping rods for reinforcing bolts are symmetrically arranged on the horizontal bracket.

[0009] Preferably, the first stopper is fixedly connected to the inner wall of the vertical bracket by a fastener. Second stoppers for restricting the steel pipe inside the vertical bracket are symmetrically arranged on the first stopper.

[0010] Preferably, a restricting groove for reducing the sinking of the second stopper is opened on the side wall of the vertical bracket.

[0011] Preferably, a first hole for fixing the steel pipe is opened in the auxiliary groove. Second holes for fixing the steel pipe are symmetrically opened on the horizontal bracket.

[0012] Preferably, the second abutting block is fixedly connected to the first abutting block through a compression spring.

[0013] Preferably, the transverse bracket is symmetrically provided with placement grooves, the placement grooves are provided with holes, and the holes communicate with the second holes. The placement grooves are provided with chutes for restricting the sliding of the clamping rods, and the inner walls of the placement grooves are provided with fixed clamping grooves for fixing the clamping rods.

[0014] The beneficial effects of the present utility model are as follows:

[0015] Through the arrangement of the clamping rod and the fixed clamping groove, after the steel pipe in the transverse bracket is fixed by bolts, it can avoid the loosening phenomenon at the bolt due to the influence of the human environment, and at the same time, the clamping rod can improve the fixing effect of the bolt after being fixed, further improving the support strength of the steel pipe in the transverse bracket.

[0016] Through the arrangement of the first abutting block and the second abutting block, after the steel pipe enters the transverse bracket and the vertical bracket, it can avoid the different distances caused by the excessive depth of the steel pipe, thereby reducing the fixing effect of the bolt on the steel pipe, further increasing the pressure burden during the support of the steel pipe, and instead increasing the overall safety hazard of the building body. Compared with the prior art, it can effectively improve the stability and convenience of the building body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Referring to Figures 1 - 4, A cross-connector for assembling the main frame of an outer protective sheet metal house, including a horizontal bracket 1 and a vertical bracket 2. The horizontal bracket 1 and the vertical bracket 2 are steel members made of aluminum alloy material in the prior art and are mainly used for the structural composition of the protective sheet metal house to improve the overall strength of the house body. The horizontal bracket 1 and the vertical bracket 2 are integrally connected by welding, which not only improves the connection strength between the two, but also facilitates the tightness during the splicing of the house body. The steel pipe 3 is a steel member used in the prior art, mainly to build the structure of the protective sheet metal house, which is convenient for later construction.

[0023] The horizontal bracket 1 is provided with a first abutting block 4 for restricting the depth of the steel pipe 3. The first abutting block 4 is integrally made of metal iron, and the surface of the metal iron is wrapped with a rubber cortex, which is used to improve the abutting effect of the steel pipe 3 while avoiding damage to the internal metal iron caused by long-term extrusion of the steel pipe 3. The first abutting block 4 is fixedly connected to the inner wall of the vertical bracket 2 through a fastener. The fastener is an auxiliary component used for connection in the prior art, which not only improves the connection strength between the two, but also facilitates the later disassembly and replacement of the two. Symmetrically arranged on the first abutting block 4 are second abutting blocks 6 for restricting the steel pipe 3 in the vertical bracket 2. The second abutting block 6 is Y-shaped, and its top is used to support the steel pipe 3 in the vertical bracket 2. At the same time, the second abutting block 6 is integrally made of metal iron, and its top is provided with an anti-slip rubber cortex, while a cavity for connecting the first abutting block 4 is opened at the bottom.

[0024] Symmetrically arranged in the vertical bracket 2 are auxiliary grooves 5 for increasing anti-slip objects. The auxiliary grooves 5 are mainly used to stably lift the steel pipe 3 in the vertical bracket 2. When there is an error in the size of the steel pipe 3 in the vertical bracket 2, other cushioning materials can be arranged in the auxiliary grooves 5, and then a hole is left. A limiting groove for reducing the sinking of the second abutting block 6 is opened on the side wall of the vertical bracket 2. The limiting groove is opened on the inner wall of the bottom of the vertical bracket 2 and is in a slope shape, and is mainly used to prevent the second abutting block 6 from shrinking downward due to long-term extrusion and having no supporting surface effect.

[0025] A first hole 7 for fixing the steel pipe 3 is opened in the auxiliary groove 5. The first hole 7 is used for fixing the steel pipe 3 in the vertical bracket 2. The steel pipe 3 is fixed by passing a bolt through the first hole 7. Symmetrically arranged on the horizontal bracket 1 are second holes 8 for fixing the steel pipe 3. The second holes 8 are bolt holes for fixing the steel pipe 3 on the horizontal bracket 1.

[0026] The second abutting block 6 is fixedly connected to the first abutting block 4 through a compression spring. The compression spring is a supporting component in the prior art, and the compression spring is fixed in the cavity of the second abutting block 6.

[0027] On the horizontal bracket 1, there are symmetrically arranged limiting clamping rods 11 for reinforcing bolts. The limiting clamping rods 11 are mainly used to fix the bolts on the second hole 8 to ensure the stability of the steel pipe 3. After the steel pipe 3 in the horizontal bracket 1 is fixed by the bolts, it can avoid the loosening phenomenon at the bolt due to the influence of the human environment. At the same time, after being fixed, the limiting clamping rods 11 can improve the fixing effect of the bolts and further improve the supporting strength of the steel pipe 3 in the horizontal bracket 1. On the horizontal bracket 1, there are symmetrically arranged placement grooves 9. The placement grooves 9 are ordinary grooves. There are holes on the placement grooves 9, and the holes are communicated with the second hole 8. There are sliding grooves 10 for the limiting clamping rods 11 to slide on the placement grooves 9. Buckles can be arranged in the sliding grooves 10 to fix the limiting clamping rods 11. The inner wall of the placement groove 9 is provided with a fixed clamping groove 12 for fixing the limiting clamping rods 11. The fixed clamping groove 12 is adapted to the front end of the limiting clamping rod 11, and then the front end of the limiting clamping rod 11 is wrapped inside.

[0028] The working principle of the present utility model is as follows:

[0029] First, the horizontal bracket 1 and the vertical bracket 2 are connected to each other by welding to form the basic structure of the main frame of the outer protective sheet metal house. Then, the steel pipe 3 is placed on the first abutting block 4 in the horizontal bracket 1, and the rubber skin layer on the first abutting block 4 is used to increase the abutting effect of the steel pipe 3 to avoid damage to the internal metal iron caused by long-term extrusion of the steel pipe 3.

[0030] Next, the second abutting block 6 is installed in the vertical bracket 2, and its top supports the steel pipe 3 in the vertical bracket 2. At the same time, it is fixedly connected to the first abutting block 4 through the cavity at the bottom. This can limit the depth of the steel pipe 3 in the vertical bracket 2. An auxiliary groove 5 is opened in the vertical bracket 2 to increase anti-slip objects and improve the stability of the steel pipe 3. When there is an error in the size of the steel pipe 3, other cushioning materials can be arranged in the auxiliary groove 5, leaving holes. A limiting groove is opened on the side wall of the vertical bracket 2, which is in a slope shape, to reduce the influence of the sinking of the second abutting block 6 and avoid the effect that the second abutting block 6 shrinks downward due to long-term extrusion without a supporting surface.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
