Specific embodiments

[0025] As Figures 1-5 shown, the present utility model provides an external frame protective frame connection structure, including a horizontal connecting sleeve 101 and a vertical connecting sleeve 102. The horizontal connecting sleeves 101 are welded on the four sides of the vertical connecting sleeve 102, and a connecting piece 200 is arranged on the outer side of the connection between the horizontal connecting sleeve 101 and the vertical connecting sleeve 102;

[0026] Embedded sleeves 103 are arranged near the outer ends of the horizontal connecting sleeve 101 and the vertical connecting sleeve 102. A fixing nut 104 is threadedly engaged with the upper end of the embedded sleeve 103. A connecting rod 106 is arranged inside the embedded sleeve 103. A fixing block 107 is fixedly installed at the upper end of the connecting rod 106. A pin shaft 109 horizontally penetrates through the fixing block 107, and a retaining rod 1010 vertically penetrates through one end of the pin shaft 109.

[0027] Further, in this embodiment, the connector 200 includes three connecting segments. Each connecting segment is formed by welding an L-shaped plate 202 and a connecting plate 201. The L-shaped plates 202 of each connecting segment are welded and fixed to each other. Based on the structure of the connector 200, the included angle formed inside adjacent connecting segments can be fitted to the outer sides of the horizontal connecting sleeve 101 and the vertical connecting sleeve 102.

[0028] In addition, two of the connecting segments are symmetrically arranged, and the other connecting segment is arranged at the bottom of the symmetric connecting segments. The connector 200 is bent and welded using bendable steel plates commonly used at the construction site, so that the connector 200 has a higher degree of fit with the horizontal connecting sleeve 101 and the vertical connecting sleeve 102.

[0029] In this embodiment, the connecting plate 201 is designed as a triangle. Connecting bolts 203 are provided between adjacent connectors 200. Due to the design of the connecting plate 201, it has a better supporting effect on the connecting columns of the horizontal connecting sleeve 101 and the vertical connecting sleeve 102. The adjacent connectors 200 are connected together by the connecting bolts 203 to achieve the stability of the connection between the horizontal connecting sleeve 101 and the vertical connecting sleeve 102.

[0030] In addition, considering the construction flexibility, four horizontal connecting sleeves 101 are not fixedly arranged on the outer side of the vertical connecting sleeve 102. The number of horizontal connecting sleeves 101 is selected according to the requirements of the connection node, and the number of connectors 200 is changed accordingly.

[0031] In this embodiment, the fixing nut 104 is welded on the surfaces of the horizontal connecting sleeve 101 and the vertical connecting sleeve 102, and mounting holes 1012 adapted to the embedded sleeve 103 are provided on the surfaces of the horizontal connecting sleeve 101 and the vertical connecting sleeve 102. The embedded sleeve 103 is in threaded cooperation with the fixing nut 104. After the embedded sleeve 103 is installed in the vertical rod 300 or the cross rod 400, the fixing nut 104 can be used to preliminarily fix the embedded sleeve 103. Through the mounting holes 1012, it is convenient to pass the embedded sleeve 103 through the mounting holes 1012 for embedding after the vertical rod 300 or the cross rod 400 is inserted.

[0032] In this embodiment, a connection hole 105 adapted to the connecting rod 106 is provided inside the embedded sleeve 103. The connecting rod 106 is in threaded fit with the connection hole 105. The fixing block 107 is designed in a convex shape. A clamping plate 108 adapted to the protruding part of the fixing block 107 is fixed at the upper end of the embedded sleeve 103. The protruding part is made of an elastic material. Through the connection hole 105, it is convenient for the connecting rod 106 to pass through the embedded sleeve 103 and be fixed by threads. Through the design of the fixing block 107, after the connecting rod 106 extends in, the protruding part will enter the clamping plate 108. After the fixed clamping plate 108 is placed with the elastic protruding part, the protruding part is extruded, and based on the elastic force, the protruding part is tightly attached to the inner side of the clamping plate 108 for clamping.

[0033] In this embodiment, the pin shaft 109 is slidably connected to the fixing block 107. A convex plate is fixed at the outer end of the pin shaft 109. A bent section 1011 is provided at the bottom of the retaining rod 1010. Through the convex plate, it is avoided that the pin shaft 109 completely passes through the fixing block 107. Through the design of the bent section 1011, the retaining rod 1010 is stuck at the other end of the pin shaft 109 to prevent the pin shaft 109 from falling off.

[0034] In this embodiment, the bottom end of the connecting rod 106 penetrates through the embedded sleeve 103, the horizontal connecting sleeve 101 and the vertical connecting sleeve 102. An extending section 1013 is provided at the bottom end of the connecting rod 106. A pin shaft 109 horizontally penetrates through the extending section 1013. By setting the pin shaft 109 and the retaining rod 1010 to cooperate in the extending section 1013, the connecting rod 106 is clamped, realizing the fixation of the connecting sleeve to the vertical rod 300 and the horizontal rod 400.

[0035] Specifically, when assembling the external frame protective rack, insert the vertical rod 300 into the vertical connecting sleeve 102, insert the horizontal rod 400 into the horizontal connecting sleeve 101, select the connection structure corresponding to the number of horizontal connecting sleeves according to the structural design, or directly weld the horizontal connecting sleeve to the outside of the vertical connecting sleeve when the number is insufficient. According to the shapes of the vertical connecting sleeve and the horizontal connecting sleeve, bend the connecting piece 200 accordingly to fit the connecting sleeve, and then connect the adjacent connecting sleeves with the connecting bolt 203 to reinforce the connection part of the connecting sleeve;

[0036] Then, the connection between the vertical rod 300 or the horizontal rod 400 and the connecting sleeve is strengthened. Taking the horizontal rod 400 as an example, after the horizontal rod 400 is inserted into the horizontal connecting sleeve, the inner end of the horizontal rod 400 abuts against the outside of the vertical fixing sleeve. According to the insertion position of the horizontal rod 400 in advance, embedded holes are pre-opened, and the embedded holes correspond to the installation holes 1012 on the horizontal connecting sleeve. Then, the embedded sleeve 103 is installed in the horizontal rod 400 by threads, and the embedded sleeve 103 is fixed by the fixing nut 104 on the horizontal connecting sleeve. Subsequently, the connecting rod 106 passes through the embedded sleeve 103, and the protruding part after the connecting rod 106 extends into the clamping plate 108 on the embedded sleeve 103. The fixed clamping plate 108 clamps the protruding part to improve the connection firmness between the connecting rod 106 and the embedded sleeve 103. Finally, pins 109 penetrate through the upper and lower ends of the connecting rod 106, the vertical rod 1010 penetrates vertically through the end of the pin 109, and the bottom end of the rod 1010 is bent. The upper end of the rod 1010 is in an arc shape with a diameter larger than the through hole, so that the rod 1010 is stuck on the other end of the pin 109, realizing that the rod 1010 clamps the pin 109, and the pin 109 clamps the connecting rod 106, making the connection between the horizontal rod 400 and the horizontal connecting sleeve more firm;

[0037] When disassembly is required, the rod 1010, the pin 109, and the connecting rod 106 are pulled out in sequence, and then the embedded sleeve 103 is screwed out to separate the vertical rod 300 or the horizontal rod 400 from the connecting sleeve, realizing rapid disassembly and assembly. Moreover, the materials of the connection structure are all steel materials easily obtained on the construction site, facilitating the adaptive adjustment of the connection structure according to the design of the vertical rod 300 and the horizontal rod 400.

[0038] The components such as the horizontal connecting sleeve 101, the vertical connecting sleeve 102, the embedded sleeve 103, the fixing nut 104, the connecting rod 106, the fixing block 107, the clamping plate 108, the pin 109, the rod 1010, the connecting piece 200, the connecting plate 201, the L-shaped plate 202, the connecting bolt 203, the vertical rod 300, and the horizontal rod 400 of the present utility model are all common standard parts or parts known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods.
