Description

Technical Field

[0001] This utility model relates to the field of space expansion technology, and in particular to a building space expansion device. Background Technology

[0002] A building space expansion device is a device used to increase the space and function of a house. It refers to adding or removing certain elements on the original basis to expand or change the original space. It involves the transformation or expansion of existing physical or virtual space to meet people's needs for space and improve their quality of life. It mainly achieves more uses by expanding and transforming existing space.

[0003] Existing technologies, such as CN214728445U, describe a rear space expansion platform device for vehicles, relating to the field of folding devices. This device includes a fixed bracket and a movable folding expansion platform. The fixed bracket is fixed to the rear of a motorhome, and the movable folding expansion platform is mounted on the fixed bracket via a power mechanism. The movable folding bracket can move up and down and expand under the action of the power mechanism. This device can be folded and installed or embedded in the rear of any vehicle. In use, the support plate can be folded and expanded at multiple angles via a pull-wire retraction device, and the support plate can also be moved up and down via a hydraulic column. This increases usable space and solves the problem of difficulty in loading and unloading heavy objects from vehicles. Furthermore, because the device is connected to the rear of the vehicle, it possesses high strength, protecting the safety of the rear of the vehicle.

[0004] To address the issue of securing the expansion board in existing equipment, which is inconvenient because the current expansion board is placed close to the ground when rotated, and its angle cannot be adjusted, it is necessary to place a pad underneath the expansion board to adjust the angle. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where expansion panels are placed close to the ground and their angle cannot be adjusted when rotated. This invention provides a building space expansion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building space expansion device, comprising a fixed frame, an installation rod, a support rod, an adjusting rod, a rotating rod, an expansion plate, and a fixing device. The installation rod is disposed on the surface of the fixed frame, the support rod is disposed on the surface of the installation rod, the adjusting rod is sleeved and connected to the surface of the support rod, the rotating rod is disposed on the surface of the installation rod, the expansion plate is rotatably connected to the surface of the rotating rod, and the fixing device is disposed on the surface of the installation rod. The fixing device includes an installation block, which is fixedly connected to the surface of the installation rod. The surface of the installation block is provided with installation holes, and the inner wall of the installation holes is threaded with studs.

[0007] Furthermore, the number of support rods is two sets and they are arranged symmetrically. A rotating seat is fixedly connected to the surface of the mounting rod. The support rod is rotatably connected to the surface of the rotating seat. A positioning hole is opened on the surface of the support rod.

[0008] Furthermore, a pin is inserted and connected to the surface of the adjusting rod, and the pin is inserted and connected to the inner wall of the positioning hole.

[0009] Furthermore, a fixing block is fixedly connected to the surface of the adjusting rod, a fixing groove is formed on the surface of the fixing block, a stabilizing spring is fixedly connected to the inner wall of the fixing groove, and a pull block is fixedly connected to the end of the stabilizing spring away from the fixing groove.

[0010] Furthermore, a plug rod is fixedly connected to the surface of the pull block, and a slot is provided on the side of the expansion plate. There are two sets of slots arranged symmetrically, and the plug rod is inserted into the inner wall of the slot.

[0011] Furthermore, each of the mounting rods has a positioning groove on its surface, and a return spring is fixedly connected to the inner wall of the positioning groove.

[0012] Furthermore, a U-shaped rod is fixedly connected to the end of the return spring away from the positioning groove, and the U-shaped rod is disposed on the surface of the mounting rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a fixing device, the use of the support rod is more convenient when fixing and supporting the expansion plate. To do this, the mounting rod is attached to the fixing frame, and then the stud is rotated to fix the mounting rod to the surface of the fixing frame. The expansion plate is then rotated to place it horizontally. The U-shaped rod is then pulled, causing the return spring to stretch and extend. The support rod is then rotated, and the adjusting rod is adjusted to the appropriate position. The pin is then inserted into the inner wall of the positioning hole. The pull block is pulled, causing the stabilizing spring to stretch and expand, and the insertion rod follows. The insertion rod is then aligned with the slot. The pull block is released, causing the stabilizing spring to spring back and insert the insertion rod into the inner wall of the slot, thus stabilizing the expansion plate.

[0015] By setting up a fixing device, the expansion board can be easily fixed and supported, avoiding the inconvenience of placing the existing expansion board close to the ground when rotating it, which cannot be adjusted at the angle and requires padding under the expansion board to adjust the angle. This effectively improves the ease of use of the equipment. Attached Figure Description

[0024] Please see Figures 1-6 This utility model provides a technical solution: a building space expansion device, including a fixed frame 1, an installation rod 2, a support rod 3, an adjusting rod 4, a rotating rod 5, an expansion plate 6, and a fixing device 7. The installation rod 2 is disposed on the surface of the fixed frame 1, the support rod 3 is disposed on the surface of the installation rod 2, the adjusting rod 4 is sleeved and connected to the surface of the support rod 3, the rotating rod 5 is disposed on the surface of the installation rod 2, the expansion plate 6 is rotatably connected to the surface of the rotating rod 5, and the fixing device 7 is disposed on the surface of the installation rod 2.

[0025] The specific setup and function of the fixing device 7 will be explained in detail below.

[0026] In this embodiment: the fixing device 7 includes a mounting block 71, which is fixedly connected to the surface of the mounting rod 2. The surface of the mounting block 71 is provided with mounting holes 72, and the inner wall of the mounting hole 72 is threaded with a stud 73.

[0027] The effect achieved by the above components is that by setting the stud 73, it is easy to fix the mounting rod 2 to the surface of the fixed frame 1.

[0028] Specifically, there are two sets of support rods 3 arranged symmetrically. A rotating seat 74 is fixedly connected to the surface of the mounting rod 2. The support rod 3 is rotatably connected to the surface of the rotating seat 74. A positioning hole 75 is opened on the surface of the support rod 3.

[0029] The effect achieved by the above components is that by setting the positioning hole 75, the length of the support rod 3 can be easily adjusted, so that the placement angle of the extension plate 6 can be adjusted in various ways.

[0030] Specifically, a pin 76 is inserted and connected to the surface of the adjusting rod 4, and the pin 76 is inserted and connected to the inner wall of the positioning hole 75.

[0031] The effect achieved by the above components is that by setting the connection between the pin 76 and the positioning hole 75, it is easy to fix the support rod 3 and the adjusting rod 4 together, making it difficult to adjust.

[0032] Specifically, a fixing block 77 is fixedly connected to the surface of the adjusting rod 4, a fixing groove 78 is opened on the surface of the fixing block 77, a stabilizing spring 79 is fixedly connected to the inner wall of the fixing groove 78, and a pull block 710 is fixedly connected to the end of the stabilizing spring 79 away from the fixing groove 78.

[0033] The effect achieved by the above components is that, by setting a stabilizing spring 79, when the pull block 710 is released, the rebound force of the stabilizing spring 79 can drive the insertion rod 711 to move.

[0034] Specifically, the surface of the pull block 710 is fixedly connected with a plug rod 711, and the side of the expansion plate 6 is provided with a slot 712. There are two sets of slots 712 arranged symmetrically, and the plug rod 711 is inserted and connected to the inner wall of the slot 712.

[0035] The effect achieved by the above components is that by setting the connection between the plug rod 711 and the slot 712, it is easy to fix the angle of the expansion plate 6, so that the expansion plate 6 is supported stably.

[0036] Specifically, each of the mounting rods 2 has a positioning groove 713 on its surface, and a return spring 714 is fixedly connected to the inner wall of the positioning groove 713.

[0037] The effect achieved by the above components is that by setting a return spring 714, the U-shaped rod 715 can easily spring back to its original position after moving.

[0038] Specifically, a U-shaped rod 715 is fixedly connected to the end of the return spring 714 away from the positioning groove 713, and the U-shaped rod 715 is set on the surface of the mounting rod 2.

[0039] The effect achieved by the above components is as follows: by setting the U-shaped rod 715, it is easy to store the support rod 3. When the extension plate 6 is retracted, the support rod 3 is placed vertically and is prone to shaking. Placing the support rod 3 inside the U-shaped rod 715 prevents the support rod 3 from shaking.

[0040] Working principle: By setting the fixing device 7, the support rod 3 is more convenient to use when fixing and supporting the expansion plate 6. The mounting rod 2 is then attached to the fixing frame 1, and the stud 73 is rotated to fix the mounting rod 2 to the surface of the fixing frame 1. The expansion plate 6 is then rotated to place it horizontally. The U-shaped rod 715 is then pulled, causing the return spring 714 to stretch and extend. The support rod 3 is then rotated, and the adjusting rod 4 is adjusted to the appropriate position. The pin 76 is then inserted into the inner wall of the positioning hole 75, and the pull block 710 is pulled, stabilizing the spring 714. 9. When stretched and expanded by force, the insertion rod 711 moves accordingly, aligning the insertion rod 711 with the slot 712. The pull block 710 is released, and the stabilizing spring 79 loses its restraint and rebounds, causing the insertion rod 711 to be inserted into the inner wall of the slot 712. The expansion plate 6 is then stabilized. The fixing device 7 facilitates the fixing and support of the expansion plate 6, avoiding the inconvenience of placing the existing expansion plate 6 close to the ground when rotating and placing it, which cannot be adjusted at the angle and requires padding under the expansion plate 6 to adjust the angle. This effectively improves the ease of use of the equipment.
