Detailed Implementation

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0025] Please see Figure 1-7 The present invention provides a clamping and fixing assembly, including a clamping device 1. The clamping device 1 includes an upper clamping part 10 and a lower clamping part 11 disposed at the bottom end of the upper clamping part 10. A gap for clamping is formed between the upper clamping part 10 and the lower clamping part 11. The top end of the lower clamping part 11 is recessed with a receiving groove 12. The heightening block 2 is disposed in the receiving groove 12, and its top is flush with the top of the lower clamping part 11. The top of the heightening block 2 is recessed downward and has a pressing groove 20, and the bottom of the pressing groove 20 is spirally raised upward. The rotating device 3 is rotatably disposed on the top surface of the heightening block 2, and its bottom end is provided with a first protrusion 30 that fits against the bottom of the extrusion groove 20.

[0026] In the above structure, the user inserts the edge of the object to be clamped, such as a table or chair, into the gap of the clamping device. The upper clamping part of the clamping device presses against the top surface of the object under gravity. The user rotates the rotating device, causing the first protrusion at its bottom to rotate as well. The bottom of the first protrusion is in contact with the bottom surface of the extrusion groove. As the rotating device rotates, it moves upward synchronously along the spirally raised bottom surface of the extrusion groove, and the rotating device rises accordingly until the top of the rotating device presses against the bottom surface of the object being clamped. The friction between the contact surface of the first protrusion and the extrusion groove locks the rotating device, thus enabling the clamping device to achieve a clamping effect. The overall clamping and fixing assembly replaces the screw-operated clamping by rotating and lifting, reducing the number of parts required for manufacturing the product and thus reducing costs.

[0027] Specifically, the upper clamping part 10 has a recessed guide groove 100 on one side, and the lower clamping part 11 has a protruding guide block 110 that cooperates with the guide groove 100. The cooperation between the guide block and the guide groove can fix the upper and lower clamping parts and facilitate the user's assembly of the upper and lower clamping parts.

[0028] Specifically, the upper clamping part 10 is provided with a fixing part 101 at its top end. The fixing part is used to insert components such as earphone stems and placement plates, so as to place items such as earphones and mobile phones.

[0029] Specifically, one side of the rotating device 3 extends outward to form a pusher 31, which allows the user to apply force more effectively to rotate the rotating device.

[0030] Specifically, a second protrusion 120 is provided at the center of the receiving groove 12, and a stop hole 121 is provided in the second protrusion 120. The stop hole 121 is a rounded rectangle. A stop protrusion 21 is provided at the center of the bottom end of the heightening block 2, which is used to cooperate with the stop hole 121. The stop protrusion 21 is a rounded rectangle. The cooperation between the stop hole and the stop protrusion of the rounded rectangle can fix the heightening block and prevent the heightening block from rotating.

[0031] Specifically, the second protrusion 120 has a first protrusion 122 and a second protrusion 123 distributed on both sides. The stop protrusion 21 has a third protrusion 210 that cooperates with the first protrusion 122 and a fourth protrusion 211 that cooperates with the second protrusion 123 at both ends. The first and third protrusions are staggered, and the second and fourth protrusions are staggered. When the clamping area is too narrow, the gap between the upper clamping part and the lower clamping part is too large. The lifting block is placed in the opposite direction so that the first protrusion abuts against the fourth protrusion and the second protrusion abuts against the third protrusion. Thus, the top surface of the lifting block is higher than the surface of the lower clamping part, reducing the gap. This allows the clamping and fixing assembly to be applicable to more clamping areas.

[0032] Specifically, a limiting hole 212 is provided at the center of the stop protrusion 21, and a limiting protrusion 32 is provided at the bottom of the rotating device 3 to cooperate with the limiting hole 212. The cooperation between the limiting hole and the limiting protrusion can ensure that the position of the rotating device does not shift during the rotation process.

[0033] Specifically, silicone is provided on the bottom surface of the extrusion groove 20 and the first protrusion 30. The silicone can increase the friction between the first protrusion and the extrusion groove, and at the same time effectively prevent the first protrusion and the extrusion groove from directly contacting each other and thus wearing each other.

[0034] Specifically, there are two first protrusions 30 evenly distributed along the circumferential direction at the bottom of the rotating device 3, and the bottom of the first protrusion 30 spirals downward, while the bottom of the extrusion groove 20 spirals upward corresponding to the first protrusion 30. The bottom of the first protrusion spirals downward and is symmetrically distributed, and the bottom surface of the extrusion groove that cooperates with it also symmetrically rises upward to cooperate with the first protrusion, so that the visual effect is not abrupt and the overall aesthetics are enhanced. At the same time, the symmetrical design makes the overall force uniform and the structure stable.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
