Description

Technical Field

[0001] This utility model relates to the field of musical instrument auxiliary equipment technology, and in particular to a drum frame structure. Background Technology

[0002] As a supporting structure for drum instruments, the drum stand is mainly used to house components such as the drum plate and sound source to meet the needs of performance. The ease of storage and stability of the drum stand are key concerns in existing drum stand structures. CN219180186U discloses a drum stand structure for a smart electronic drum, including a horizontal drum stand tube, a floor tube, a folding and rotating shaft, and connector tubes. The horizontal drum stand tube is a hollow circular tube, consisting of four tubes: three straight tubes and one curved tube, with one straight tube having no connection at one end. There are two folding and rotating shafts; one shaft connects to the curved tube at the top and to the straight tube at the bottom, while the other shaft connects to the straight tube at the top. The system includes two bend-type connectors, one of which connects to a straight pipe at the middle and lower parts. The other connector has a sealing plug at the top. Four hollow, round, straight drum frame tubes are used for grounding. Two of these tubes connect to their respective folding and rotating shafts at the top, while the remaining two connect to their corresponding connectors. External devices are connected via adapters on the connectors. All cables are routed within the channel formed by the drum frame's horizontal tubes, the folding and rotating shafts, and the connectors. Branch cables exit through pre-drilled holes on the folding and rotating shafts.

[0003] In existing technologies, the stability of the part of the drum frame that contacts the ground for support is insufficient, and there is a possibility of tipping over during use. Currently, suction cups are installed at the bottom of the drum frame to improve the stability of the drum frame installation through the adsorption of the suction cups; however, the suction force of the suction cups makes it inconvenient to disassemble the drum frame. Therefore, a drum frame structure with high stability and easy installation and disassembly is needed. Utility Model Content

[0004] This invention provides a drum frame structure that is highly stable and easy to install and disassemble, in order to solve the problem of inconvenient installation and disassembly of existing drum frames.

[0005] In view of this, the present invention aims to provide a drum frame structure, in which the drum frame structure includes a horizontal mounting tube and a vertical support tube disposed at the bottom of the horizontal mounting tube, and a support member is provided at the bottom of the vertical support tube;

[0006] The support includes a support base, a suction cup located at the bottom of the support base, and a telescopic venting component and a locking component located inside the support base; the top of the support base is for the bottom of the vertical support tube to be inserted, and the bottom of the vertical support tube is provided with a first return spring; the two ends of the telescopic venting component are connected to the vertical support tube and the suction cup.

[0007] The telescopic exhaust device is configured with three workstations based on the distance between the vertical support tube and the suction cup;

[0008] At the first working position, the suction cup is connected to the outside world through the telescopic exhaust component;

[0009] At the second work station, the suction cup cuts off the connection with the outside world through the telescopic exhaust component and generates an adsorption force, while the locking component locks the vertical support tube.

[0010] At the third station, the locking device is unlocked from the vertical support tube.

[0011] Furthermore, a first air hole is provided on the side of the support base.

[0012] Furthermore, the telescopic exhaust component includes a fixed rod, a movable sleeve, and a toggle post arranged sequentially from bottom to top; the fixed rod is fixed to the inner bottom of the support base, and an airflow channel running vertically through the fixed rod is provided inside the fixed rod, the airflow channel being connected to the suction cup;

[0013] The top of the movable sleeve is connected to the actuating post, and the bottom of the movable sleeve has a slot. A second return spring is provided in the slot. The top of the fixing rod is inserted into the slot and connected to the second return spring. A second air hole communicating with the slot is provided on the side of the movable sleeve. In the first working position, the suction cup, airflow channel, slot and second air hole are connected in sequence. In the second working position, the fixing rod closes the second air hole.

[0014] Furthermore, the locking component includes a fixed hook plate, a movable hook plate, and a torsion spring; the fixed hook plate is fixed to the bottom of the vertical support tube, the middle part of the movable hook plate is rotatably mounted inside the support seat through a bearing, the torsion spring abuts against one end of the movable hook plate, and the torsion spring can drive the movable hook plate to move closer to the fixed hook plate.

[0015] The drum frame structure disclosed in this utility model uses suction cups to adsorb and support the drum frame. While ensuring the stability of the support, by setting up telescopic exhaust components, support seats and locking components, the suction cup can be adsorbed by simply controlling the downward pressure of the vertical support tube. This ensures stable installation and fixation while conveniently controlling the installation and disassembly of the drum frame.

[0029] In the existing technology, the stability of the part of the drum frame that contacts the ground for support is insufficient, and there is a possibility of tipping over during use. Currently, a suction cup 320 is installed at the bottom of the drum frame to improve the stability of the drum frame installation through the adsorption of the suction cup 320; however, the suction force of the suction cup 320 makes it inconvenient to disassemble the drum frame. Therefore, a drum frame structure with high stability and easy installation and disassembly is needed.

[0030] This utility model provides a drum frame structure, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the drum frame structure includes a horizontal mounting tube 100 and a vertical support tube 200. The vertical support tube 200 is installed at the bottom of the horizontal mounting tube 100 for support. There are three horizontal mounting tubes 100 and four vertical support tubes 200. All the tubes are detachably connected together by connectors, which facilitates the disassembly and installation of the drum frame and facilitates transportation after disassembly. Support members 300 are provided at the bottom of each of the four vertical support tubes 200.

[0031] To achieve stable support and convenient installation and disassembly, such as Figure 4As shown, the support component 300 is configured as a support base 310, a suction cup 320, a telescopic exhaust component 330, and a locking component 340. The suction cup 320 is located at the bottom of the support base 310, which can adsorb and fix each support base 310 to the ground. The telescopic exhaust component 330 and the locking component 340 are both located inside the support base 310. The telescopic exhaust component 330 connects the vertical support tube 200 and the support base 310 and allows them to move relative to each other. The locking component 340 is used to restrict relative movement between the vertical support tube 200 and the support base 310 when locked, that is, locking during installation can ensure the stability of the drum frame installation. The top of the support base 310 is for the bottom of the vertical support tube 200 to be inserted for connection. A first return spring 350 is provided at the bottom of the support tube 200. The first return spring 350 connects the vertical support tube 200 and the support base 310. The first return spring 350 can drive the vertical support tube 200 to return to its original position when it moves downward. The bottom of the telescopic exhaust component 330 can communicate with the suction cup 320. The telescopic exhaust component 330 is set with three working positions according to the distance between the vertical support tube 200 and the suction cup 320. That is, the extension and retraction of the telescopic exhaust component 330 is determined by the distance between the vertical support tube 200 and the suction cup 320, that is, the height of the vertical support tube 200 is divided into three working positions, which are briefly referred to as the first working position, the second working position and the third working position in this embodiment, as follows:

[0032] At the first work station, this state is usually used for handling before installation. The suction cup 320 first connects to the inside of the support base 310 through the telescopic exhaust component 330, thereby connecting to the outside. At this time, the suction cup 320 is connected to the outside atmosphere and the suction cup 320 has no suction force.

[0033] In the second work station, this state is the post-installation usage state. At least part of the gas in the suction cup 320 is discharged, and the connection between the suction cup 320 and the outside world is cut off by the telescopic exhaust component 330, so that the suction cup 320 generates suction force, improving the stability during drum frame installation; and in this state, the locking component 340 locks the vertical support tube 200, restricting the movement of the vertical support tube 200 during use, so that the suction cup 320 always maintains suction force;

[0034] In the third station, it is usually used for disassembly after the drum frame has been used. The locking device 340 is unlocked to lock the vertical support tube 200, which drives the vertical support tube 200 to reset upward, so that the suction cup 320 is connected to the atmosphere and loses its suction force, making it easy to disassemble the support base 310.

[0035] In order to enable the interior of the support base 310 to communicate with the outside, a first vent 360 is provided on the side of the support base 310 to allow gas inside the support base 310 to be discharged and outside gas to enter the interior.

[0036] Regarding the telescopic exhaust component 330, such as Figure 5 and Figure 6 As shown, the telescopic exhaust component 330 is configured as a fixed rod 331, a movable sleeve 332, and a detonating post 333. The fixed rod 331, movable sleeve 332, and detonating post 333 are arranged sequentially from bottom to top. The fixed rod 331 is vertically fixed to the inner bottom of the support base 310, and an airflow channel 334 is formed inside the fixed rod 331. The airflow channel 334 is vertically arranged and extends vertically through the fixed rod 331. The bottom end of the airflow channel 334 communicates with the suction cup 320, and the top end of the airflow channel 334 communicates with the interior of the movable sleeve 332. The movable sleeve 332 is located at the top of the fixed rod 331, and the detonating post 333 is fixed at the top of the movable sleeve 332. The diameter of the detonating post 333 is larger than the diameter of the movable sleeve 332, and the diameter of the movable sleeve 332 is larger than the diameter of the fixed rod 331. The bottom of the movable sleeve 332 has a slot 335, and a second return spring 337 is installed in the slot 335. The top of the fixing rod 331 is inserted into the slot 335. One end of the second return spring 337 is connected to the fixing rod 331. The second return spring 337 is used to drive the movable sleeve 332 to move upward and reset. The side of the movable sleeve 332 has a second air hole 336 that communicates with the slot 335. The second air hole 336 allows the suction cup 320 to communicate with the interior of the support base 310. In the first working position, the suction cup 320, the airflow channel 334, the slot 335 and the second air hole 336 are connected in sequence, so that the suction cup 320 communicates with the outside. In the second working position, the fixing rod 331 closes the second air hole 336, so that the suction cup 320 maintains negative pressure for adsorption.

[0037] Regarding the locking component 340, it is configured as a fixed hook plate 341, a movable hook plate 342, and a torsion spring 343. The fixed hook plate 341 is installed at the bottom of the vertical support tube 200 by screws, and the fixed hook plate 341 is located inside the support base 310. The middle part of the movable hook plate 342 is rotatably installed inside the support base 310 via a bearing, so that the movable hook plate 342 can rotate within the support base 310. When the movable hook plate 342 rotates to engage with the fixed hook plate 341, the movable hook plate 342 and the fixed hook plate 341 engage. The fixed hook plate 341 is locked in place, thereby restricting the movement of the vertical support tube 200; the torsion spring 343 abuts against one end of the movable hook plate 342, and the torsion spring 343 can drive the movable hook plate 342 to move closer to the fixed hook plate 341, that is, the torsion spring 343 can drive the movable hook plate 342 to tend to cooperate and lock with the fixed hook plate 341; and when the actuating column 333 moves downward, it can actuate the movable hook plate 342 to rotate, so that the movable hook plate 342 separates from the fixed hook plate 341, and the restriction on the vertical support tube 200 is released.

[0038] The working principle of this utility model is as follows: When the drum frame needs to be installed, the horizontal mounting tube 100 is connected to the vertical support tube 200. Then, the vertical support tube 200 is placed vertically on the ground. Gently press the vertical support tube 200 downwards, causing it to move downwards from the first position to the second position, i.e., from... Figure 5 Switch to Figure 6 State; At this time, the fixed hook plate 341 moves downward a certain distance along with the vertical support tube 200, so that the fixed hook plate 341 and the movable hook plate 342 cooperate to fasten and restrict the movement of the vertical support tube 200, and also keep the second air hole 336 closed. At the same time as the vertical support tube 200 moves downward, the actuating column 333 and the movable sleeve 332 move downward together, pressing the gas in the suction cup 320 and the airflow channel 334 to be discharged from the second air hole 336 or the side of the suction cup 320. When the vertical support tube 200 is stopped and pressed down, under the action of the first return spring 350 and the second return spring 337, the vertical support tube 200 will be driven to return to the upper position a small distance. The movable sleeve 332 will also return to the upper position a small distance at the same time. At this time, a negative pressure will be formed in the airflow channel 334. Combined with the negative pressure formed by the suction cup 320 itself being squeezed, the support seat 310 will be adsorbed and fixed on the ground.

[0039] When disassembly is required, press the vertical support tube 200 downwards to cause the actuating column 333 to move the movable hook plate 342, separating the movable hook plate 342 from the fixed hook plate 341. Then, quickly pull the vertical support tube 200 upwards to separate the support base 310 from the ground. Specifically, the separation of the movable hook plate 342 from the fixed hook plate 341 no longer restricts the upward movement of the vertical support plate, and when pressed downwards, the movable sleeve 332 moves downwards simultaneously, allowing the airflow channel 334 and the suction... The internal space of the air chamber formed by the disc 320 and the slot 335 is reduced, and the negative pressure inside will almost disappear. The suction cup 320 no longer has suction force. When the vertical support tube 200 is pulled upward, the support base 310 can be lifted together. Even if the support base 310 is not separated at that time, when the vertical support tube 200 moves upward, the fixing rod 331 no longer closes the second air hole 336. The airflow channel 334 and the suction cup 320 will be connected to the outside, thereby allowing the support base 310 to quickly separate from the ground.

[0040] With the above technical solution, the suction cup 320 can be adsorbed simply by controlling the downward pressure of the vertical support tube 200, making it easy to control the installation and disassembly of the drum frame.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
