Description

Technical Field

[0001] This utility model relates to the field of single-sided portable drum technology, and in particular to a single-sided portable drum hook. Background Technology

[0002] A single-sided portable drum is a small, portable percussion instrument that typically consists of a drum body and a drumhead. The drum body is a ring-shaped structure that is easy to hold, while the drumhead has lugs on the edge to help securely mount the drumhead to one side of the drum body, ensuring stable use.

[0003] In the existing technology, during the installation and use of a single-sided portable drum, the conventional installation method requires pre-drilling mounting holes on the drum body to ensure the stability of the drumhead installation. The installation and fixation are then carried out using bolts and fasteners. This not only takes up a lot of space and affects the portability of the single-sided drum, but also the drilling connection will affect the subsequent drum sound of the single-sided drum. In addition, it is inconvenient to disassemble and replace the drumhead when it is damaged in the future. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of conventional installation methods in the prior art, which require pre-drilling mounting holes on the drum body and using bolts and fasteners for installation and fixation in order to ensure the stability of the drumhead installation. This not only takes up a lot of space and affects the portability of the single-sided drum, but also the drilling connection will affect the subsequent drum sound of the single-sided drum. At the same time, it is inconvenient to disassemble and replace the drumhead when it is damaged and needs to be replaced. The proposed single-sided portable drum hook is to solve these problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-sided portable drum hook includes a hook body with a through hole inside. An internally threaded tube is inserted into the inner wall of the hook body at the through hole. The top inner wall of the internally threaded tube has a first chamfer. The bottom inner wall of the hook body at the through hole has an opening. A retaining ring is fixedly connected to the wall of the internally threaded tube. The retaining ring has a second chamfer at several corners. The inner wall of the opening matches the retaining ring. The retaining ring is clamped onto the inner wall of the hook body at the opening. A connecting screw is threaded onto the inner wall of the internally threaded tube.

[0007] Preferably, a rubber washer is inserted into the inner wall of the bottom end of the hook body at the opening, and the inner wall of the rubber washer is pressed against the wall of the internally threaded tube.

[0008] Preferably, the top end of the connecting screw extends above the internally threaded tube and is fixedly connected to a knob.

[0009] Preferably, the hook body has a slot on the left inner wall, and the hook body has a rounded corner on the inner wall of the slot.

[0010] Preferably, a wear-resistant pad is fixedly connected to the inner wall of the hook body located in the slot.

[0011] Preferably, the hook body has multiple anti-slip protrusions on the inner wall of the slot, and the upper surface of the multiple anti-slip protrusions is set as an arc surface.

[0012] Compared with the prior art, this utility model provides a single-sided portable drum hook, which has the following features:

[0013] Beneficial effects:

[0014] 1. This single-sided portable drum hook is designed to secure the hook body to the side of the drum body away from the drum surface by locking the hook body into a slot. The connecting screw passes through the drum lug at the edge of the drum surface, and the knob is pressed onto the drum lug. Rotating the knob extends the thread of the connecting screw into the interior of the internal threaded tube. By adjusting the length of the connecting screw inside the internal threaded tube, a tight connection can be made, allowing the hook body and the drum surface to be pressed firmly onto both sides of the drum body, ensuring stable installation of the drum surface.

[0015] 2. This single-sided portable drum hook has a second chamfer at the corner of the retaining ring, which can be clamped onto the inner wall of the opening, improving the stability of the internal thread tube inside the hook body and preventing the internal thread tube from rotating with the connecting screw.

[0016] 3. This single-sided portable drum hook uses rubber washers to reduce wear on the hook body at the bottom of the through hole, wear-resistant pads to reduce wear on the inner wall of the slot and the drum body, and anti-slip ridges to improve the stability of the hook body after the sleeve is tightened and prevent slippage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A single-sided portable drum hook includes a hook body 1. The hook body 1 has a through hole inside. An internally threaded tube 2 is inserted into the inner wall of the hook body 1 in the through hole. The top inner wall of the internally threaded tube 2 has a first chamfer. The bottom inner wall of the hook body 1 in the through hole has an opening. A retaining ring 3 is fixedly connected to the tube wall of the internally threaded tube 2. The retaining ring 3 has a second chamfer at several corners. The inner wall of the opening matches the retaining ring 3. The retaining ring 3 is clamped in the inner wall of the hook body 1 in the opening. A connecting screw 5 is threadedly connected to the inner wall of the internally threaded tube 2. A slot is opened on the left inner wall of the hook body 1. The inner wall of the hook body 1 in the slot has a rounded corner. The top wall of the connecting screw 5 extends to the top of the internally threaded tube 2 and is fixedly connected to a knob 6.

[0023] In use, the hook body 1 is secured to the side of the drum body away from the drum surface by locking the slot. Then, the connecting screw 5 is inserted through the drum lug at the edge of the drum surface, and the knob 6 is pressed onto the drum lug. This allows the drum lug and the drum surface to be pressed tightly onto the mounting surface of the drum body. Rotating the knob 6 extends the thread of the connecting screw 5 into the interior of the internal thread tube 2. By adjusting the length of the connecting screw 5 inside the internal thread tube 2, a tight connection can be made, allowing the hook body 1 and the drum surface to be pressed tightly onto both sides of the drum body, ensuring stable installation of the drum surface. Subsequently, reversing the knob 6 moves the connecting screw 5 out to the outside of the internal thread tube 2, facilitating the removal and disassembly of the drum surface. The non-drilling connection method reduces the impact on the drum body and facilitates the removal and replacement of the drum surface.

[0024] Meanwhile, the corners of the retaining ring 3 are provided with second chamfers that can be clamped onto the inner wall of the opening, improving the stability of the internal thread tube 2 inside the hook body 1 and preventing the internal thread tube 2 from rotating with the connecting screw 5.

[0025] To improve the stability of the hook body 1 after the sleeve is tightened and prevent slippage, such as Figure 1-3 As shown, a rubber washer 4 is inserted into the inner wall of the bottom end of the hook body 1 at the opening. The inner wall of the rubber washer 4 is pressed against the wall of the internally threaded tube 2. A wear-resistant pad 7 is fixedly connected to the inner wall of the hook body 1 at the slot opening. Multiple anti-slip ridges 8 are provided on the inner wall of the hook body 1 at the slot opening. The upper surface of the multiple anti-slip ridges 8 is set as an arc surface.

[0026] The rubber washer 4 can reduce the wear of the hook body 1 at the bottom of the through hole, the wear-resistant pad 7 can reduce the wear of the hook body 1 on the inner wall of the slot and the drum, and the anti-slip convex strip 8 can improve the stability of the hook body 1 after the sleeve is tightened and prevent slippage.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
