[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings.
[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0036] Please refer to Figures 1 to 5 The embodiment of the utility model provides a connecting rod structure of a timpani, wherein the timpani 1 comprises a drum body 11, a drum ring 14 is sleeved on the top of the drum body 11, the drum body 11 has a first axis, the extension direction of the first axis is a first direction, a plurality of support frames 13 uniformly distributed along the circumferential direction are arranged on the outer surface of the drum body 11, the cross section of the support frame 13 is U-shaped, and the opening direction faces the first axis side, wherein the first direction is Figure 1In the vertical direction, each support frame 13 is provided with a base 12 at the bottom end, and is placed on the ground through the base 12 to ensure the stability of each support frame 13 and the drum body 11. The connecting rod structure includes:
[0037] A drum skin pull plate 15 is coaxially arranged below the drum body 11, and a plurality of second connecting rods 5 are evenly distributed along the circumferential direction on the edge of the drum skin pull plate 15;
[0038] A plurality of second connection mechanisms 4, including a connection plate 41 disposed at the end of the corresponding second connection rod 5 away from the drum skin pull plate 15, the end of the connection plate 41 away from the drum skin pull plate 15 is provided with a connection cylinder 42, a fourth shaft 45 is penetrated through the middle of the connection cylinder 42, the connection cylinder 42 and the fourth shaft 45 are both located inside the support frame 13, and the two ends of the fourth shaft 45 are respectively rotatably connected to the side walls of the support frame 13;
[0039] A plurality of pull rods 2 are arranged inside each of the support frames 13, the bottom end of each of the pull rods 2 is rotatably connected to the middle of the corresponding connecting plate 41, and the top end of each of the pull rods 2 is connected to the drum ring 14;
[0040] like Figure 1 and Figure 2 As shown, the diameter of the drum skin pull plate 15 is smaller than the diameter of the drum body 11, and the pull rod 2 is placed inside the support frame 13, so it needs to be connected and transmitted through the second connecting rod 5. In the second connecting mechanism 4, the fulcrum of the connecting plate 41 is arranged away from the end of the drum skin pull plate 15, that is, the fourth shaft 45, and the connection with the pull rod 2 is located in the middle of the connecting plate 41, and the connection with the second connecting rod 5 is arranged close to the end of the drum skin pull plate 15. Therefore, when the second connecting rod 5 applies a pulling force, it has a longer lever arm. According to the principle that the longer the torque, the less effort is required, compared with the vertical downward pull in the prior art, the performer in the utility model will save more effort when driving the drum skin pull plate 15 to move downward.
[0041] In some embodiments, one end of the second connecting rod 5 is rotatably connected to the drum skin pull plate 15, and the other end is rotatably connected to the connecting plate 41, and a plane formed by the rotation of the second connecting rod 5 is perpendicular to the axis of the fourth rotating shaft 45;
[0042] like Figure 2 As shown, if welding or bolts are used as connection methods, the second connecting rod 5 will get stuck. However, the rotational connection at both ends of the second connecting rod 5 allows the second connecting rod 5 to rotate around the fourth rotating shaft 45 when the drum skin pulling plate 15 moves downward, thereby ensuring the purpose of stably pulling the pull rod 2.
[0043] In some embodiments, both ends of the second connecting rod 5 are equipped with connecting hooks 51, the edge of the drum skin pull plate 15 is provided with a plurality of connecting holes evenly distributed along the circumferential direction, and the two sides of the connecting plate 41 away from the connecting cylinder 42 are respectively provided with second clamping plates 43, and a third rotating shaft 44 is penetrated between the two second clamping plates 43;
[0044] The connecting hook 51 at one end of the second connecting rod 5 is hooked and connected with the corresponding connecting hole, and the connecting hook 51 at the other end is hooked and connected with the third rotating shaft 44;
[0045] like Figure 2 and Figure 3 As shown, the rotation connection between the two ends of the second connecting rod 5 is achieved by hooking the connecting hook 51, and it is more convenient to install and disassemble using the connecting hook 51, so that the user can quickly install and disassemble the second connecting rod 5.
[0046] In some embodiments, the connecting plate 41 is in the shape of a し-shaped, the third rotating shaft 44 is disposed at the top of the し-shaped, the fourth rotating shaft 45 is located at the bottom of the し-shaped, away from the drum skin pull plate 15, and the connection between the pull rod 2 and the connecting plate 41 is located at the し-shaped bend;
[0047] like Figure 2 and Figure 3 As shown, in order to ensure better pulling of the connecting plate 41 to rotate around the fourth rotating shaft 45, from the force model, the connecting plate 41 should be a vertical long strip, so that the end of the connecting plate 41 away from the fourth rotating shaft 45 can be more easily pulled by the second connecting rod 5, thereby saving effort. However, considering that the second connecting rod 5 may interfere with the pull rod 2 in actual conditions, the connecting plate 41 is set to be a し-shaped one on the basis of the above, which not only ensures the purpose of saving effort, but also does not cause interference between the second connecting rod 5 and the pull rod 2. Moreover, the し-shaped connecting plate 41 has higher strength than the long strip and is not prone to breakage or damage.
[0048] In some embodiments, a first connecting mechanism 3 is provided at the top of the pull rod 2, and the first connecting mechanism 3 includes a connecting seat 31 provided on the side surface of the drum hoop 14, a first connecting rod 32 is penetrated in the connecting seat 31, and a triangular plate 35 is rotatably connected to the bottom end of the first connecting rod 32, and the bottom end of the triangular plate 35 is rotatably connected to the top of the pull rod 2;
[0049] like Figure 2 and Figure 5As shown, the bottom end of the pull rod 2 is driven to rotate by the connecting plate 41, so that the pull rod 2 moves downward, but this downward movement is not vertically downward, and the connection seat 31 is connected to the drum ring 14 and will not rotate. Therefore, the first connecting rod 32 and the triangular plate 35 are set. The first connecting rod 32 is fixedly connected to the connecting seat 31 and always maintains a vertical state. The triangular plate 35 is then used to buffer the deflection of the pull rod 2 in other directions, reduce the deflection of the first connecting rod 32 in other directions, and make the first connecting rod 32 move vertically downward, thereby completing the purpose of adjusting the drum ring 14. In addition, the top of the support frame 13 is provided with a first connecting rod 3 2 runs through the avoidance channel to prevent the support frame 13 from interfering with the first connecting rod 32. The first connecting rod 32 is provided with two first clamping plates 33 at the end away from the connecting seat 31. The two first clamping plates 33 are respectively located on both sides of the triangular plate 35. The first rotating shaft 34 is then provided to pass through the two first clamping plates 33 and the triangular plate 35 to achieve rotational connection. Optionally, the first connecting rod 32 includes a long bolt and an internally threaded sleeve threadedly connected to the long bolt. The connecting seat 31 is penetrated by a countersunk hole. The long bolt passes through the countersunk hole and is inserted into the internally threaded sleeve. The two first clamping plates 33 are arranged at the end of the internally threaded sleeve away from the long bolt.
[0050] In some embodiments, a second rotating shaft 36 is provided through the triangular plate 35 away from the first axis end, and both ends of the second rotating shaft 36 are rotatably connected to the side walls of the support frame 13 respectively;
[0051] like Figure 1 , Figure 2 and Figure 5 As shown, since the triangular plate 35 is always in a suspended state, it is easy to shake. After the drum hoop 14 is adjusted, the swing of the triangular plate 35 may cause the position of the drum hoop 14 to shift. Therefore, the triangular plate 35 is fixed by the support frame 13 to ensure the stability of the triangular plate 35 and the first connecting rod 32, thereby reducing the position shift of the drum hoop 14 after adjustment.
[0052] In some embodiments, both ends of the pull rod 2 are provided with quick-install components 6, and the quick-install components 6 are used for quick installation of the top end of the pull rod 2 and the triangular plate 35 and the bottom end of the pull rod 2 and the connecting plate 41;
[0053] like Figure 2 and Figure 4 As shown, the quick installation of the two ends of the pull rod 2 is achieved through the quick assembly assembly 6, making the assembly more convenient and quick, reducing the assembly time and improving the assembly efficiency.
[0054] In some embodiments, the quick-release assembly 6 includes a connecting block 61 connected to the pull rod 2, the connecting block 61 is provided with a slot 62 at the end away from the pull rod 2, the connecting plate 41 or the triangular plate 35 is inserted into the slot 62, the connecting block 61 is provided with a compensation block 63 near the end of the pull rod 2, the compensation block 63 is covered with an open collar 67, the open end of the open collar 67 is provided with a warping edge 610 extending outward, the open collar 67 is provided with an elastic plate 68 at the end away from the pull rod 2, the elastic plate 68 is provided with a fixed shaft 69 at the end away from the open collar 67, the fixed shaft 69 passes through the slot 62, and passes through the connecting plate 41 or the triangular plate 35;
[0055] like Figure 4 As shown, the connecting block 61 is located away from the end of the compensation block 63, the connecting plate 41 is located close to the end of the pull rod 2, and the triangular plate 35 is located close to the end of the pull rod 2. Through holes for the fixed shaft 69 to pass through are formed. By bending the elastic plate 68, the fixed shaft 69 can be pulled out from the corresponding through hole, so that the connecting block 61 can be quickly taken out. In addition, the opening of the open ring 67 can be enlarged by pulling the warped edge 610, so that the open ring 67 can be taken out from the compensation block 63, and the open ring 67 can also be quickly replaced, so that when the fixed shaft 69 or the elastic plate 68 is damaged, they can be quickly replaced.
[0056] In some embodiments, a screw hole 64 is formed through the middle of the compensation block 63 and the connecting block 61, and external threads 65 are provided at the top and bottom of the pull rod 2. The pull rod 2 and the compensation block 63 are connected by the external threads 65 and the screw hole 64. The compensation block 63 is provided with a locking nut 66 that is connected with the external threads 65 on the side away from the connecting block 61.
[0057] like Figure 2 and Figure 4 As shown, by rotating the pull rod 2, the pull rod 2 is extended or retracted along the screw hole 64 through the action of the thread, which is convenient for compensating and adjusting according to the actual length of the support frame 13 to avoid the situation where it is too short or too long and inconvenient to install. In addition, since other components are connected by rotating the fixed shaft 69, the pull rod 2 can also be adjusted after installation, which is convenient for the performer to better control. Finally, when locking is required, the locking nut 66 is rotated to make the locking nut 66 abut against the compensation block 63, and the static friction of the thread is increased by the axial pressure of the thread, thereby playing a tightening role.
