technical field

The invention relates to a fast-expandable foldable drum stand and a use method thereof, belonging to the technical field of hardware processing.

Background technique

With the improvement of people's living standards, there are more and more drum learners, and the demand for drum racks also increases. However, the drum racks in the market are all connected by rods. The assembly of drum racks requires Professionals are required to install it, and it is time-consuming and labor-intensive. Due to the large volume of the drum kit bracket, it is very inconvenient to transport when carrying out performances, and the on-site installation is time-consuming, which cannot meet the requirements of the stage for rapid installation and transfer of equipment, so it brings great inconvenience to the users of the drum kit . In addition, most of the existing drum racks are single drum racks, and it is impossible to provide a bracket suitable for multiple drums and realize the installation of multiple drums on the drum rack at the same time. The device has a complex structure and high cost, and is difficult to be widely popularized.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a fast-deployable foldable drum stand.

The present invention also provides a method for using the above-mentioned stent.

Technical scheme of the present invention is as follows:

A fast-deployable foldable drum stand, including a rod set, a connecting piece, and a support foot for the drum stand;

The connecting piece includes a rod connecting buckle and a folding structure; the rod connecting buckle includes two connecting blocks, a through hole is formed in the middle of the connecting block, the through hole matches the rod group, and a rotating shaft is arranged between the two connecting blocks. The two connecting blocks can rotate relative to each other according to the rotating shaft; the folding mechanism includes reinforcing rods, and connecting rods are hinged at both ends of the reinforcing rods;

The rod set includes at least two vertical rods and at least two horizontal rods, a horizontal rod is arranged between two adjacent vertical rods, and the horizontal rods are connected to the vertical rods through rod connection buckles; between two adjacent horizontal rods are connected by a folding structure;

The supporting feet of the drum stand include a tripod rod set and a quick-release connector, and the tripod rod set is connected to the vertical rod through the quick-release connector.

Preferably, the connecting member further includes a rod positioning member, the rod positioning member includes two hinged positioning rods, the positioning rods are respectively connected to the adjacent horizontal rods and vertical rods, and the deployment angle of the two positioning rods is at most 180°. When the bracket is unfolded from the folded state, along with the relative rotation of the cross bar and the vertical bar, the two positioning bars are unfolded from the folded state. When the cross bar and the vertical bar are at 90 degrees, the two positioning bars are fully expanded to 180°, the axis coincides as a whole to form a "one" shape, the cross bar and the vertical bar will not be able to rotate, and the bar positioning part has just played a positioning effect that makes the cross bar and the vertical bar expand to 90 degrees and then stop. It ensures the parallel relationship between the vertical bar and the vertical bar, the horizontal bar and the horizontal bar, and also ensures the vertical relationship between the vertical bar and the horizontal bar, and quickly completes the position determination between the bars of the bar group when the bracket is rapidly deployed. It greatly simplifies the complex positioning work between the rods of the rod group when unfolding, and ensures the position accuracy between the rods of the drum stand.

Preferably, adjacent ends of the two crossbars are hollow, and the outer diameter of the folded structure is smaller than the inner diameter of the hollow cavity of the crossbars. When the cross bar is unfolded horizontally, the folded structure between the cross bars is inserted into the hollow cavity of the cross bar, and the reinforcing bar is used to reinforce the horizontal connection of the cross bar.

Further preferably, an annular stopper is provided at the ports adjacent to one end of the two cross bars, and a connecting head is provided at one end of the connecting rod of the folding structure, the width of the connecting head is greater than the inner diameter of the ring stopper, and the outer diameter of the connecting rod is smaller than the ring stopper inner diameter. When the crossbar is unfolded horizontally, the folding structure retracts into the hollow cavity of the crossbar; when the crossbar is folded, the reinforcing rod is outside the crossbar, and due to the action of the ring stopper, the connecting head of the connecting rod remains in the hollow cavity of the crossbar. Keep the crossbar connected to the folded structure.

Further preferably, the linear distance between the ring stopper and the end face of the cross bar is 35mm.

Preferably, the connecting piece further includes a component connection buckle, the component connection buckle is provided on the horizontal bar or the vertical bar, and the component connection buckle is used for connecting the accessories and the bracket. Connect the other accessories of the drum kit except the drum stand to the drum stand.

The buckle of the component connection can be fully opened without inserting from one end of the tube, which makes the use very convenient and quick.

Preferably, the supporting feet of the drum stand further include fine-tuning knobs, and the fine-tuning knobs are arranged at the bottom of the tripod rod set. Due to the uneven ground, when the height of the three supporting points of the drum stand needs to be adjusted, it can be adjusted through the fine-tuning knob, which provides a strong guarantee for the overall stability of the drum stand.

Preferably, the tripod rod set includes three transverse support rods, and the three support rods are spaced 120° apart from each other. It ensures the overall stability of the drum rack bracket, and can also withstand relatively large forces, so as to meet the requirements for the installation and use of multiple drum racks and their equipment.

Preferably, the quick-release connector of the support foot of the drum stand includes a circular hoop, the inner diameter of which is matched with the diameter of the vertical bar, and one end of the circular hoop is provided with a fastening bolt, and the fastening bolt is connected with an opening and closing handle, and the opening and closing handle is provided with Eccentric structure. When the opening and closing handle is loosened, the hoop is loosened, and the vertical bar can be put in or taken out. After putting in the vertical bar, the opening and closing handle can be fastened, and the hoop is tightened by the eccentric structure, thereby fixing the vertical bar. The quick-release connector realizes the quick disassembly and assembly of the support feet of the drum stand, which greatly facilitates the installation of the support feet of the drum stand and improves the efficiency of drum stand assembly.

A method for using a quick-deployable foldable drum kit comprising the following steps:

When quickly unfolding in the folded state, it is first necessary to pull the two outermost vertical bars of the bar group, and with the assistance of the bar positioning parts, lift the horizontal bar so that the horizontal bar connected to the vertical bar is lifted horizontally, and the horizontal bar The angle between the rod and the vertical rod is 90°; secondly, through the folding structure between the horizontal rods, the connecting rods at both ends of the folding structure and the reinforcing rods are horizontal, and the folding structure is inserted into the cavity of the horizontal rod, and half of the folding members are in the opposite direction. The two adjacent crossbars play the role of fixed connection and support; then the vertical bar is connected to the tripod rod group through the quick-release connector of the drum stand support foot to complete the overall assembly of the bracket, and finally check the three-legged rod group. Whether the three fulcrums are on the ground at the same time, if some fulcrums are suspended in the air, the three fulcrums of the drum stand support feet are placed on the ground at the same time through the fine-tuning knob, thus ensuring the stability of the overall drum mechanism;
