[0019] The following further describes the specific embodiments of the present application in detail. It should be understood that the description of the present application herein is not intended to limit the scope of protection of the present application.

[0020] As shown in Figures 1 to 5 Fig. 1, which is a structural schematic view of the novel spring pre-pressing ratchet 360-degree adjustable hook provided by the present application. The novel spring pre-pressing ratchet 360-degree adjustable hook is installed on a mounting rod 10, and comprises a hook assembly 20 fixedly connected to the mounting rod 10, and an audio housing 30 fixedly connected to the hook assembly 20. It is conceivable that the novel spring pre-pressing ratchet 360-degree adjustable hook should also comprise some other functional components, such as fastening components, mounting components, etc., which are all prior art known to those skilled in the art and will not be described herein.

[0021] The mounting rod 10 is used to install the novel spring pre-pressing ratchet 360-degree adjustable hook at a place where audio is needed to be set, which can be a handrail of a yacht or other rod-like structure that can be used to install the novel spring pre-pressing ratchet 360-degree adjustable hook. Preferably, the cross section of the mounting rod 10 can be circular or other shapes, so that the mounting rod 10 and the hook assembly 20 are more closely contacted. The mounting rod 10 itself should be a prior art, which will not be described herein.

[0022] As shown in Figure 3 Fig. 2, the hook assembly 20 comprises a hook 21 sleeved on the mounting rod 10, a hook seat 22 fixedly connected to the hook 21, a rotating seat 23 elastically connected to the hook seat 22, and an elastic connecting assembly 24 used to connect the hook seat 22 and the rotating seat 23.

[0023] The hook 21 comprises a sleeving portion 211 having a radial opening, and two connecting portions 212 respectively arranged on the radial opening of the sleeving portion 211.

[0024] The size and shape of the sleeving portion 211 can be matched with the mounting rod 10, so as to sleeve the hook 21 on the mounting rod 10.

[0025] The two connecting portions 212 are respectively arranged at both ends of the opening of the sleeving portion 211, and are inclinedly arranged in the shape of an "8". Two connecting holes are formed on each of the connecting portions 212. During installation, the connecting portions 212 can be fixedly connected to the hook seat 22 by screws or other fasteners, so that the hook 21 and the hook seat 22 form a closed ring, and the novel spring pre-pressing ratchet 360-degree adjustable hook is hung on the mounting rod 10.

[0026] The hook base 22 comprises a hook base body 221, a connecting shaft 222 arranged on the hook base body 221 and away from the hook 21, and a first ratchet ring 223 arranged on the hook base body 221 and away from the hook 21.

[0027] The hook base body 221 is used for locking and fixing the hook 21, and the side thereof facing the hook 21 is in the shape of an "M". The two sides of the "M" shape of the hook base body 221 are arranged in the form of inclined surfaces adapted to the connecting portion 212. Meanwhile, threaded holes are also arranged on the hook base body 221 to facilitate the connection of the hook 21 and the hook base 22. Preferably, the two inclined surfaces of the hook base body 221 connecting with the connecting portion 212 are in the form of an arc structure. The radius of the arc structure is consistent with the radius of the hook 21. Therefore, when the hook 21 and the hook base body 221 are connected together, the arc structure and the sleeving portion 211 of the hook 21 can form a complete circle, so that the hook assembly 20 can be fitted on the mounting rod 10.

[0028] The connecting shaft 222 can be centrally arranged on the side of the hook base body 221 facing the rotating base 23, and comprises a connecting shaft body 2221, two annular grooves 2222 arranged on the side of the connecting shaft body 2221 facing the hook base body 221, a connecting thread 2223 arranged on the side of the annular groove 2222, and a limiting edge 2224 arranged on the side of the connecting thread 2223. The connecting shaft 222 is used for arranging the elastic connecting assembly 24, which will be described in detail below in connection with the elastic connecting assembly 24.

[0029] The first ratchet ring 223 is located at the end of the hook base body 221 facing the rotating base 23 and is arranged around the outside of the connecting shaft 222. The first ratchet ring 223 is formed by a plurality of teeth arranged in the circumferential direction of the hook base body 221. The teeth can be in the form of a triangular prism structure. The two sides of the triangular prism structure have inclined surfaces, thereby forming a guide when the teeth are staggered, facilitating rotation. The first ratchet ring 223 cooperates with the second ratchet ring 232 of the rotating base 23, thereby realizing the 360-degree rotational connection between the hook base 22 and the rotating base 23, which will be described in further detail below in connection with the rotating base 23.

[0030] The rotating seat 23 comprises a rotating seat body 231, a second ratchet ring 232 arranged on the side of the rotating seat body 231 facing the hook seat 22, an elastic element mounting hole 233 located in the middle of the rotating seat body 231, a plurality of fixing columns 234 located on the side of the rotating seat body 231 facing the sound casing 30, a lock pressing block 235 fixedly connected with the fixing columns 234, and a spring accommodating groove 236 arranged in the rotating seat body 231.

[0031] The end of the rotating seat body 231 facing the hook seat 22 is adapted to the hook seat body 221, so as to facilitate the connection of the hook seat body 221. The end of the rotating seat body 231 facing the sound casing 30 is adapted to the shape of the sound casing 30, so that the rotating seat body 231 can be attached to the surface of the sound casing 30, and the connection between the sound casing 30 and the rotating seat 23 is more stable.

[0032] The second ratchet ring 232 is arranged in matching with the first ratchet ring 223. The second ratchet ring 232 is also formed by a plurality of teeth arranged in the circumferential direction. When the rotating seat 23 and the hook seat 22 are connected together, the second ratchet ring 232 and the first ratchet ring 223 are engaged together. When the rotating seat 23 is rotated, the second ratchet ring 232 and the first ratchet ring 223 can be relatively rotated, so that the position relationship between the rotating seat 23 and the hook seat 22 can be adjusted, and the angle of the sound casing 30 fixedly connected to the rotating seat 23 can be adjusted by 360 degrees.

[0033] The elastic element mounting hole 233 is centrally arranged on the rotating seat body 231 and penetrates the rotating seat body 231 in the axial direction of the rotating seat body 231. The elastic element mounting hole 233 is used for penetrating the connecting shaft 222. The connecting shaft 222 penetrates the elastic element mounting hole 233 and is connected with the elastic connection assembly 24, so the size of the elastic element mounting hole 233 should be adapted to the size of the connecting shaft 222.

[0034] A plurality of the fixing columns 234 are symmetrically arranged on the side of the rotating seat body 231 facing the sound casing 30 and penetrate the sound casing 30 and the lock pressing block 235 in sequence. The fixing columns 234 are provided with axial threaded holes, so that fasteners such as connecting bolts can be connected thereto to connect and fix the lock pressing block 235 and the sound casing 30.

[0035] The lock block 235 is provided with a plurality of mounting holes corresponding to the fixing columns 234, so as to be connected to the rotating seat body 231 by fasteners. When the sound casing 30 is connected and fixed, the lock block 235 is located inside the sound casing 30, and the rotating seat body 231 is located outside the sound casing 30. It is conceived that the sound casing 30 should also be provided with corresponding mounting holes. The fixing columns 234 pass through the mounting holes of the sound casing 30 and the lock block 235, and then a fastener such as a screw is used to fix one side of the free end of the fixing column 234, so as to fix the sound casing 30 between the lock block 235 and the rotating seat body 231. Preferably, a gasket such as a spring gasket can also be arranged between the sound casing 30 and the rotating seat body 231, so as to avoid loosening between the rotating seat 231 and the sound casing 30.

[0036] The spring accommodating groove 236 is an annular groove arranged on the rotating seat body 231, which is used to accommodate and limit the spring 243 of the elastic connecting member 24. Details will be further described below in combination with the spring 243.

[0037] The elastic connecting assembly 24 comprises a spring base 241 screwed on the connecting shaft 222, a limiting snap spring 242 located at one end of the spring base 241, and a spring 243 sleeved on the connecting shaft 222.

[0038] The spring base 241 is used to support the spring 243. The cross section of the spring base 241 is in T-shaped structure. The spring base 241 is connected to the connecting shaft 222 by the connecting thread 2223.

[0039] The snap spring 242 is located on the side opposite to the hook 21 of the spring base 241. One side of the snap spring 242 abuts against the spring base 241, and the other side abuts against the limiting flange 2224, so as to limit the axial displacement of the spring base 241, so as to avoid loosening between the spring base 241 and the connecting shaft 222 when the sound casing 30 vibrates during use, and further avoid the spring base 241 from falling off from the connecting shaft 222.

[0040] The spring 243 is sleeved on the connecting shaft body 2221, one end of the spring 243 abuts against the other side of the spring base 241, the other end of the spring 243 abuts against the spring accommodating groove 236 and abuts against the rotating seat body 231, so that the elastic connection is formed between the hook seat 22 and the rotating seat 23. Further, a spring washer, such as a wave-shaped elastic washer, can be arranged on the side where the spring 243 abuts against the spring base 241. The arrangement of the spring washer can improve the stability of the spring 243, reduce the impact and vibration received by the spring 243 during the working process, and improve the service life of the spring 243.

[0041] The hook 21 and the hook seat 22 of the new spring pre-pressing ratchet 360-degree adjustable hook are fixedly connected together. The connecting shaft 222 of the hook seat 22 is fixedly connected with the spring base 241 through the elastic element mounting hole 233 of the rotating seat 23. Preferably, at least one sealing ring 244, which can be an O-shaped sealing ring, is arranged between the connecting shaft 222 and the inner side wall of the elastic element mounting hole 233 and is accommodated in the annular groove 2222. The sealing ring 244 can fill the gap between the connecting shaft 222 and the inner side wall of the elastic element mounting hole 233 to avoid the left and right shaking of the connecting shaft 222 in the elastic element mounting hole 233, thereby causing the rotating seat 23 to tilt, resulting in a gap between the second ratchet ring 232 and the first ratchet ring 223, which is not conducive to rotation or causes difficulty in rotation. One end of the spring 243 is sleeved outside the spring base 241 and abuts against one side of the spring base 241. The other side of the spring 243 is inserted into the spring accommodating groove 236 of the rotating seat 23, so that the hook seat 22 and the rotating seat 23 are elastically connected. When the angle of the new spring pre-pressing ratchet 360-degree adjustable hook does not need to be adjusted, the hook seat 22 and the rotating seat 23 abut against each other under the elastic force of the spring, and the second ratchet ring 232 and the first ratchet ring 223 are in meshing state. When the angle needs to be adjusted, only the rotating seat 23 needs to be rotated, so that the second ratchet ring 232 and the first ratchet ring 223 are relatively rotated. And because of the existence of the spring 243, when the teeth of the second ratchet ring 232 and the first ratchet ring 223 abut against each other, the connecting shaft 222 is pulled up, thereby compressing the spring 243 to provide a rotating space for the second ratchet ring 232 and the first ratchet ring 223, so that the rotating seat 23 can be adjusted by 360 degrees. When the angle adjustment is completed and the hand is released, the spring 243 loses the pulling force and returns to its original state, and under the action of the opening force, the connecting shaft 222 is pulled down, so that the second ratchet ring 232 and the first ratchet ring 223 are meshed together, thereby forming an angle fixation.

[0042] The sound shell 30 is used to accommodate the sound, so that the sound is hung in the place where the sound is needed to be set through the hook assembly 20. The structure and size of the sound shell 30 can be matched and selected according to the set sound. The sound shell 30 itself should be a prior art, which will not be described here.

[0043] Compared with the prior art, the novel spring pre-pressing ratchet 360-degree adjustable hook has the hook assembly 20 which comprises a hook 21 sleeved on the mounting rod 10, a hook seat 22 fixedly connected with the hook 21, a rotating seat 23 rotatably arranged on the hook seat 22, and an elastic connecting assembly 24 arranged in the rotating seat 23. The hook seat 22 and the rotating seat 23 are rotatably connected through the first ratchet ring 223 and the second ratchet ring 232. Meanwhile, the arrangement of the elastic connecting assembly 24 not only provides a rotating space between the first ratchet ring 223 and the second ratchet ring 232, but also realizes automatic resetting after rotation, so that the first ratchet ring 223 and the second ratchet ring 232 return to the meshing state, and the angle is fixed. Therefore, the novel spring pre-pressing ratchet 360-degree adjustable hook can be adjusted at any angle of 360 degrees, the adjustment operation is simple, and automatic positioning can be realized after the adjustment is completed.

[0044] The above is only a preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement within the utility model spirit is covered in the utility model claim scope.
