[0029] As Figure 1 and Figure 2As shown, an embodiment of the utility model provides a foundation pit combined steel support device, including a main body 1, the inner wall of the main body 1 is tightly fitted with a support plate 2, the top of the support plate 2 is provided with a groove 3, the inner wall of the groove 3 is tightly fitted with a support bar 5, the outer wall of the support bar 5 is slidably connected with a shell 4, the inner wall of the shell 4 is fixedly equipped with a cross bar 17, the outer wall of the cross bar 17 is sleeved with a return spring 15, the support bar 5 is located at one end of the inner wall of the shell 4 and is fixedly equipped with a screw 16, the outer wall of the screw 16 is threadedly connected with a nut 13, the outer wall of the shell 4 is provided with a slide groove 8, the end of the support bar 5 away from the shell 4 is fixedly equipped with a positioning block 10, both sides of the positioning block 10 are provided with a clamping hole 11, the outer wall of the support plate 2 is respectively fixedly equipped with a supporting plate 9 and a connecting plate 12, the outer wall of the connecting plate 12 is abutted with a retaining spring 14, the outer wall of the connecting plate 12 is provided with a sleeve 7, and the middle part of the retaining spring 14 is sleeved with a clamping rod 6. By setting the structure of the main body 1, support plate 2, groove 3, shell 4, support bar 5, clamping rod 6, sleeve 7, support plate 9, positioning block 10 and clamping hole 11, when installing the support device, the user can directly align the support bar 5 with the groove 3, and then press the support bar 5 downward, so that the positioning block 10 displaces the clamping rod 6 and the sleeve 7, so that the position of the clamping hole 11 corresponds to the position of the clamping rod 6 and the sleeve 7 respectively, and the elasticity of the retaining spring 14 is utilized to make the clamping rod 6 and the sleeve 7 simultaneously plugged into a clamping hole 11, so as to achieve the effect of quickly assembling the support device, thereby improving the user's assembly efficiency of the support device.

[0030] like Figure 1 and Figure 2 As shown, the inner wall of the sleeve 7 is slidably connected to the outer wall of the clamping rod 6, the number of the clamping rods 6 and the sleeves 7 is several, and the several clamping rods 6 and the sleeves 7 are evenly distributed along the outer wall of the support plate 2. By setting up several clamping rods 6 and sleeve 7 structures, the support plate 2 and the support strips 5 are supported by several support strips 5 after installation, thereby ensuring the fit between the support plate 2 and the main body 1, thereby improving the stability of the support device after assembly and ensuring the supporting effect on the main body 1.

[0031] like Figure 1 and Figure 3As shown, a sliding hole is provided on the outer wall of the connecting plate 12, and the inner wall of the sliding hole is slidably connected to the outer wall of the clamping rod 6 and the sleeve 7 respectively. The outer walls of the clamping rod 6 and the sleeve 7 are fixedly sleeved with a limiting ring, and the diameter of the limiting ring is larger than the diameter of the sliding hole. Through the provided sliding hole and limiting ring structure, when the user presses the support bar 5 downward, the displacement force of the positioning block 10 on the clamping rod 6 and the sleeve 7 is used to make the limiting ring compress the retaining spring 14, so that the clamping rod 6 and the sleeve 7 move in the opposite direction, so that the support bar 5 can continue to descend until it contacts the bottom of the inner wall of the groove 3, so that the clamping rod 6 and the sleeve 7 are respectively plugged into a clamping hole 11, thereby realizing the effect of quickly fixing the support bar 5 and ensuring that the support plate 2 is tightly fitted with the inner wall of the main body 1, thereby improving the user's assembly efficiency of the support device.

[0032] like Figure 3 and Figure 5 As shown, the diameter of the card hole 11 is respectively matched with the diameter of the card rod 6 and the sleeve 7, and when the inner wall of the card hole 11 is plugged into the outer wall of the card rod 6 and the sleeve 7, the bottom of the positioning block 10 is tightly fitted with the top of the support plate 9, and the bottom of the inner wall of the groove 3 is tightly fitted with the outer wall of the support bar 5. Through the set card rod 6, sleeve 7 and card hole 11 structure, when the inner wall of the groove 3 is tightly fitted with the outer wall of the support bar 5, the card rod 6 and the sleeve 7 are respectively plugged into a card hole 11, so that when the support plate 2 is subjected to the pressure of the main body 1, the support bar 5 will be squeezed and move upward. At this time, the card rod 6 and the sleeve 7 will block the movement of the support bar 5, thereby ensuring the supporting effect of the support bar 5 on the support plate 2, thereby improving the stability of the support device.

[0033] like Figure 4 and Figure 5 As shown, the support bar 5 is located at one end of the inner wall of the shell 4 and is fixedly equipped with a limit plate, the outer wall of the limit plate is slidably connected to the inner wall of the shell 4, a circular hole is opened on the outer wall of the limit plate, and the inner wall of the circular hole is slidably connected to the outer wall of the cross bar 17. Through the set limit plate and circular hole structure, the user can adjust the length between the shell 4 and the support bar 5 by pulling the support bar 5 when assembling the support device, thereby facilitating the user to install the support device for the main body 1 of different sizes, thereby improving the use range of the support device.

[0034] like Figure 5As shown, there is a 1-cm gap between the outer wall of the screw 16 and the inner wall of the chute 8. When the outer wall of the nut 13 is in close contact with the outer wall of the housing 4, the support bar 5 is in a fixed connection state with the housing 4. Through the structure of the screw 16 and the chute 8 provided, by tightening and releasing the nut 13, it is convenient for the user to adjust and fix the support bar 5 respectively, so as to ensure that the distance between the housing 4 and the support bar 5 can be fixed after adjustment, and further ensure the support and limiting effects of the housing 4 and the support bar 5 on the support plate 2, further improving the stability of the support device.

[0035] For the technical solution provided by the present utility model, both support plates 2 are placed in the body 1, so that the outer wall of the support plate 2 is in close contact with the inner wall of the body 1. Then pick up a support bar 5, loosen the nut 13, and then pull the support bar 5 to adjust the length of the housing 4 and the support bar 5 until the two support bars 5 can be respectively aligned with a groove 3. Then tighten the nut 13 to fix the housing 4 and the support bar 5. Then press the support bar 5 so that the outer walls of the positioning blocks 10 are in close contact with the outer walls of the clamping rods 6 and the sleeves 7 respectively. Under the action of the pressure, the positioning blocks 10 push the clamping rods 6 and the sleeves 7 to move in opposite directions. When the positions of the clamping rods 6 and the sleeves 7 respectively correspond to the positions of a clamping hole 11, use the elasticity of the clamping spring 14 to send the clamping rods 6 and the sleeves 7 into the clamping hole 11 to achieve the effect of quickly fixing the support bar 5, improving the assembly efficiency of the support device by the user.
