Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

As shown in fig. 1-5, a scaffold with an adjustable base comprises a scaffold body, four connecting rods 1 are arranged at the bottom of the scaffold body in an array and in the vertical direction, supporting legs 2 are arranged at the bottom ends of the connecting rods 1, as shown in fig. 5, the supporting legs 2 are of a conventional structure and comprise an adjusting rod and a base, wherein the base is connected with the bottom of the adjusting rod, the base is in contact with the ground, the fitting degree of the ball pair can be increased, the vertical position of the base can be adjusted by rotating the adjusting rod, when a plurality of supporting rods 3 are vertically and rotatably arranged on the circular array at the outer periphery of the connecting rod 1, adjusting components 4 acting on the plurality of supporting rods 3 are arranged on the connecting rod 1, the free ends of the plurality of supporting rods 3 are formed to be close to or far away from each other through the adjusting components 4, so as to form a plurality of supporting rods 3 perpendicular to the connecting rod 1, supporting rods 5 are obliquely and slidably arranged on the supporting rods 3 along the length direction, the support rods 3 are provided with driving members 6 for adjusting the movement of the support columns 5, when the support columns 5 are vertical to the corresponding connecting rods 1, the support columns 5 are moved and contacted with the ground through the driving members 6, when the scaffold is used, the scaffold is placed at a proper position, the support legs 2 are positioned on the ground, if part of the support legs 2 are not contacted with the ground due to uneven ground, the adjusting rods of the support legs 2 can be rotated to make the bases of the support legs 2 contacted with the ground, if the ground is uneven, the support columns 3 can be separated from each other by adjusting the adjusting assemblies 4 until the support columns are vertical to the corresponding connecting rods 1, the support columns 5 are not contacted with the ground, then the support columns 5 are moved downwards in an inclined manner by adjusting the driving members 6, as shown in fig. 5, when the support columns 3 are vertical to the connecting rods 1, make support column 5 be vertical to slope downstream through driving piece 6, until the bottom and the ground contact of support column 5, thereby form and support, thereby can support supporting legs 2 with the ground part contact, thereby can prevent this scaffold from appearing rocking or the phenomenon of empting when using, it is to be explained, if the partial supporting legs 2 of scaffold bottom is good with the ground laminating degree, then need not support through support column 5, the device compares with current, thereby make support column 5 and ground support through adjusting part 4 and driving piece 6, thereby support area has been improved, thereby can make scaffold subaerial placing stability of hole or unevenness, be difficult to appear rocking and need not place the gasket bottom the supporting leg, consequently, the practicality is more.

As shown in fig. 2 and 5, in some embodiments, the adjusting assembly 4 includes a sliding sleeve 401 sleeved on the connecting rod 1, a hinge rod 402 is hinged on the support rod 3, a free end of the hinge rod 402 is hinged on the sliding sleeve 401, an adjusting member 7 for driving the sliding sleeve 401 to move is installed on the connecting rod 1, when it is required to rotate a plurality of support rods 3 on one connecting rod 1, the sliding sleeve 401 is moved by the adjusting member 7, so that the hinge rod 402 hinged to the sliding sleeve 401 is moved, because both ends of the hinge rod 402 are hinged, the sliding sleeve 401 is moved to pull the plurality of support rods 3 to rotate through the hinge rod 402, so that the plurality of support rods 3 rotate synchronously.

As shown in fig. 2 and 5, in some embodiments, the portion of the connecting rod 1 above the sliding sleeve 401 is threaded; adjusting part 7 includes that the screw thread section of thick bamboo 701 of threaded bush on connecting rod 1 is established, sliding sleeve 401 top is rotated and is installed and change cover 702 coaxial with connecting rod 1, the body of rod 703 has set firmly between changeing cover 702 and the screw thread section of thick bamboo 701, when rotating screw thread section of thick bamboo 701, screw thread section of thick bamboo 701 rotates and can drive body of rod 703 and rotate, body of rod 703 rotates and drives and change cover 702 and rotate, because it is normal to the removal with sliding sleeve 401 to change cover 702, can stimulate sliding sleeve 401 when the rotatory vertical removal of screw thread section of thick bamboo 701, thereby indirect a plurality of bracing pieces 3 of drive rotate, because screw-thread fit has auto-lock nature, so bracing piece 3 is difficult to lead to bracing piece 3 to rotate by oneself because of external influence after rotating certain angle.

As shown in fig. 2 and 5, in some embodiments, a through groove 601 is formed in the support rod 3 along the length direction thereof, and the support column 5 is obliquely and slidably disposed in the through groove 601; the driving part 6 internally comprises a threaded rod 602 which is rotatably installed in the through groove 601, the threaded rod 602 and the support column 5 are in the same inclination direction, one end of the threaded rod passes through the through groove 601 and is located outside, the support column 5 is in threaded sleeve connection with the threaded rod 602, when the moving position of the support column 5 needs to be adjusted, the threaded rod 602 is rotated, and the threaded rod 602 rotates to drive the support column 5 to move along the axis direction of the threaded rod 602, so that the purpose of moving the support column 5 is achieved.

As shown in fig. 2 and 5, in some embodiments, a limiting block 8 attached to the cross section of the through groove 601 is fixedly disposed at the top of the supporting column 5, the limiting block 8 is located inside the through groove 601 and is threadedly sleeved on the threaded rod 602, and since the limiting block 8 is matched with the cross section of the through groove 601, when the threaded rod 602 is rotated, the limiting block of the through groove 601 limits the rotation angle of the supporting column 5, so that the supporting column 5 moves.

As shown in fig. 1, fig. 2 and fig. 5, in some embodiments, a plurality of vertical placing grooves 9 are formed in a circular array on the outer periphery of the connecting rod 1, the supporting rod 3 is rotatably installed in the placing grooves 9 through a rotating shaft, it should be noted that the sliding sleeve 401 is slidably sleeved on the connecting rod 1, and the inner cross section of the sliding sleeve 401 is attached to the plurality of placing grooves 9, so that the sliding sleeve 401 is limited, the sliding sleeve 401 can only vertically move and cannot rotate around the axis of the connecting rod 1, and the supporting rod 3 is rotatably received in the corresponding placing groove 9 when the supporting rod 3 is not used due to the design of the placing grooves 9, so that the occupied space is reduced.

As shown in fig. 2 and 5, in some embodiments, the bottom of the supporting pole 5 is tapered and has a small end that contacts the ground, and the tapered design reduces the contact area with the ground, so that the supporting pole 3 can better contact the ground in some concave or uneven positions. The situation that the bottom part of the supporting rod 3 is suspended is not easy to occur.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
