Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy metal stands, and more specifically, to an aluminum alloy metal stand which is easy to assemble and fold. Background Art

[0002] With the development of my country's economy and the improvement of people's living standards, stages are often built on important occasions. For example, stages are built for performances at weddings, school celebrations and concerts. When building a temporary stage, a stage frame is needed. The stage frame is the core tool used to support the stage.

[0003] Existing stage frames are usually assembled into a complete stage structure by splicing multiple frames, but the supporting legs in each frame cannot be hidden. When the frame is transported, the protruding supporting legs will increase the overall space occupancy rate, resulting in increased transportation costs. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an aluminum alloy metal stand that is easy to assemble and fold. The technical problem to be solved by the present invention is that the supporting legs in each stand cannot be hidden. When the stand is transported, the protruding supporting legs will increase the overall space occupancy rate, resulting in an increase in transportation costs.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An aluminum alloy metal platform that is easy to assemble and fold includes a platform, and a plurality of fixed rods are symmetrically installed on the bottom surface of the platform, and a rotating seat is fixedly installed on the bottom end of each fixed rod, and a support leg is rotatably connected in each rotating seat. The bottom surface of the platform is slidably connected to a stabilizing frame, and the stabilizing frame is slidably connected to each fixed rod. The platform drives the stabilizing frame to slide up and down through a driving mechanism, and a plurality of placement slots are provided on the bottom surface of the stabilizing frame, and a clamping sleeve is fixedly installed in each of the placement slots. A plurality of limit sleeves are fixedly installed on both sides of the bottom surface of the platform, and pins are elastically connected on the other two sides of the bottom surface of the platform.

[0007] like Figure 1-3 As shown, the specific implementation method is: by setting a fixed rod, a rotating seat, a support leg, and a stabilizing frame, the support leg can be rotated on the fixed rod, and the stability of the support leg can be enhanced by sliding the stabilizing frame in the position of the rotating seat. At the same time, through the placement groove and the clamping sleeve, the support leg can be rotated and hidden in the placement groove, and through the deformation of the arc clip on the clamping sleeve, the support leg is restricted in the placement groove, thereby realizing the folding of the support leg and reducing the space utilization rate of the device. At the same time, the pin can be quickly clamped in the limit sleeve of the outer device to realize the rapid splicing and assembly of multiple devices.

[0008] In a preferred embodiment, the driving mechanism includes an assembly seat, and the assembly seat is fixedly mounted on the bottom surface of the table, a double-headed screw is rotatably connected inside the assembly seat, two threaded sleeves are symmetrically threaded on the double-headed screw, the top surface of each threaded sleeve is rotatably connected to a connecting plate, and the other end of each connecting plate is rotatably connected to the outside of the stabilizing frame.

[0009] In a preferred embodiment, a plurality of fixed plates are fixedly installed on the bottom surface of the table, and each pin is slidably connected to the fixed plate at the corresponding position. A baffle is fixedly installed at one end of each pin, and a spring is commonly installed between each baffle and the outer side of the fixed plate at the corresponding position.

[0010] In a preferred embodiment, the stabilizing frame is in an I-shape, and each extending end of the stabilizing frame is provided with an annular sleeve, and each annular sleeve is sleeved on the outside of a corresponding fixing rod.

[0011] In a preferred embodiment, one end of the double-headed screw passes through the assembly seat and is installed with a knob. A T-shaped slot is provided in the assembly seat, and each threaded sleeve is slidably connected in the T-shaped slot.

[0012] In a preferred embodiment, the diameter length of each baffle is greater than the diameter length of the pin.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model realizes the rotation of the double-headed screw by arranging a fixing rod, a supporting leg, a stabilizing frame, a rotating seat, a placement groove, a clamping sleeve, a double-headed screw, a connecting rod and other devices, drives the two threaded sleeves to move away from each other, and under the action of the connecting rod, the stabilizing frame slides upward, thereby releasing the limit on the supporting leg. At this time, the supporting leg can be rotated and embedded in the placement groove through the clamping sleeve, thereby realizing the hidden folding of the supporting leg, thereby reducing the space utilization rate of the device and reducing the transportation cost.

[0015] 2. The utility model sets springs, pins, limit sleeves and other devices to achieve the goal of splicing multiple platform plates. The springs can be used to clamp the pins in the limit sleeves of the surrounding platform plates, thereby achieving a quick assembly connection between the two platform plates. At the same time, the action of the springs can prevent the vibration of the stage from affecting the position of the pins, thereby ensuring the stability of the platform plate connection.

[0016] To sum up, when in use, the utility model is easy to operate and can realize the hidden folding of the supporting legs in the table top, thereby reducing the space utilization rate of the device and reducing transportation costs. At the same time, it can realize the rapid splicing and assembly of multiple table tops and ensure the stability of the connection between the table tops. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-3 , an aluminum alloy metal stand that is easy to assemble and fold, includes a table plate 1, a plurality of fixed rods 2 are symmetrically installed on the bottom surface of the table plate 1, a rotating seat 13 is fixedly installed on the bottom end of each fixed rod 2, and a support leg 3 is rotatably connected in each rotating seat 13, the bottom surface of the table plate 1 is slidably connected to a stabilizing frame 4, and the stabilizing frame 4 is slidably connected to each fixed rod 2, and the table plate 1 drives the stabilizing frame 4 to slide up and down through a driving mechanism, and a plurality of placement slots 5 are opened on the bottom surface of the stabilizing frame 4, and a clamping sleeve 6 is fixedly installed in each placement slot 5, a plurality of limit sleeves 7 are fixedly installed on both sides of the bottom surface of the table plate 1, and the other two sides of the bottom surface of the table plate 1 are elastically connected with pins 10.

[0023] It is worth noting that all components in the device are made of aluminum alloy, which has a relatively low density, making the entire device light in weight. This can reduce transportation costs and labor intensity during transportation.

[0024] like Figure 1-3As shown, the specific implementation method is: by setting a fixed rod 2, a rotating seat 13, a supporting leg 3, and a stabilizing frame 4, the supporting leg 3 can be rotated on the fixed rod 2, and the stabilizing frame 4 can slide in the position of the rotating seat 13, so as to enhance the stability of the supporting leg 3. At the same time, through the placement groove 5 and the clamping sleeve 6, the supporting leg 3 can be rotated and hidden in the placement groove 5, and through the deformation of the arc clip on the clamping sleeve 6, the supporting leg 3 is restricted in the placement groove 5, thereby realizing the folding of the supporting leg 3 and reducing the space utilization rate of the device. At the same time, the pin 10 can be quickly clamped in the limiting sleeve 7 of the outer device to realize the rapid splicing and assembly of multiple devices.

[0025] The driving mechanism includes an assembly seat 14, and the assembly seat 14 is fixedly installed on the bottom surface of the table 1. A double-headed screw 16 is rotatably connected inside the assembly seat 14, and two threaded sleeves 17 are symmetrically threaded on the double-headed screw 16. The top surface of each threaded sleeve 17 is rotatably connected to a connecting plate 12, and the other end of each connecting plate 12 is rotatably connected to the outside of the stabilizing frame 4.

[0026] It is worth noting that the two sections of thread on the double-headed screw 16 are in opposite directions, and the connection point of the two sections of thread is located at the center of the double-headed screw 16, so that the two threaded sleeves 17 can slide towards each other, pushing the connecting plate 12 to rotate, thereby moving the stabilizing frame 4.

[0027] A plurality of fixed plates 8 are fixedly installed on the bottom surface of the table 1, and each pin 10 is slidably connected to the fixed plate 8 at the corresponding position. A baffle 11 is fixedly installed at one end of each pin 10, and a spring 9 is commonly installed between each baffle 11 and the outer side of the fixed plate 8 at the corresponding position.

[0028] Through the action of the spring 9, the pin 10 always extends outward, and then when multiple platform plates 1 are assembled to form a stage, the vibration on the stage will not cause the pin 10 to separate from the limiting sleeve 7, so that the stage is more stable.

[0029] The stabilizing frame 4 is in the shape of an I-beam, and each extending end of the stabilizing frame 4 is installed with an annular sleeve, and each annular sleeve is arranged on the outside of the fixed rod 2 at the corresponding position. The supporting leg 3 is limited by the annular sleeve so that it cannot rotate, thereby enhancing the stability of the device.

[0030] One end of the double-headed screw 16 passes through the assembly seat 14 and is installed with a knob 15. A T-shaped slot is provided in the assembly seat 14, and each threaded sleeve 17 is slidably connected in the T-shaped slot. The threaded sleeve 17 is limited by the T-shaped slot so that it cannot rotate and can only slide linearly.

[0031] The diameter length of each baffle 11 is greater than the diameter length of the pin 10 .

[0032] When the utility model is used, when it is necessary to assemble a stage, multiple platform boards 1 can be spliced ​​and assembled, and the bottom surface of the platform board 1 is elastically connected to the pin 10 and clamped in the limiting sleeve 7 of the surrounding platform boards 1, so as to achieve rapid splicing and assembly of two platform boards 1, and when the stage is spliced, under the action of the spring 9, the vibration on the stage will not cause the spring 9 to separate from the limiting sleeve 7, thereby enhancing the stability of the stage;

[0033] At the same time, when the stage is disassembled, the knob 15 is turned to drive the double-headed screw 16 to rotate, so that the two threaded sleeves 17 move away from each other, and drive the connecting plate 12 to rotate, so that the stabilizing frame 4 slides upward, and then the annular sleeve of the stabilizing frame 4 moves to the top of the rotating seat 13, releasing the limit on the supporting leg 3. At this time, the supporting leg 3 can be rotated and embedded in the placement groove 5 through the clamping sleeve 6, so that the supporting leg 3 can be hidden and folded, thereby reducing the space utilization rate of the device and reducing transportation costs.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
