Description

Technical Field

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a fixing device for mounting a hollow cup motor. The fixing device for mounting a hollow cup motor includes a housing 1, a clamping component 2, and a reinforcing component 3. The clamping component 2 enables quick assembly and disassembly, and the reinforcing component 3 can tighten and fix the clamping component 2, thereby improving stability.

[0030] Specifically, the clamping component 2 is installed at the bottom of the housing 1. The bottom of the housing 1 has a groove 11. A first toothed plate 21 and a second toothed plate 23 are slidably connected in the groove 11. A first gear 22 is rotatably connected in the groove 11. The first gear 22 meshes with the first toothed plate 21 and the second toothed plate 23 respectively. By opening a groove 11 inside the outer casing 1, the first toothed plate 21, the first gear 22 and the second toothed plate 23 can be installed. By pressing, the first toothed plate 21 drives the first gear 22 to rotate, which in turn drives the second toothed plate 23 to move, thereby driving the clamping block 25 to clamp and fix it.

[0031] Specifically, the reinforcing component 3 is installed on one side of the clamping component 2, including a limiting shell 36 fixed to one side of the outer shell 1. A rotating rod 32 is rotatably connected to the upper end of the limiting shell 36, and a bearing 34 is fixedly connected to the lower end of the rotating rod 32. The lower end of the rotating rod 32 is fixed to the inner ring of the bearing 34, and an inclined block 35 is fixedly connected to the outer ring of the bearing 34. The inclined block 35 slides inside the limiting shell 36.

[0032] By setting a limiting shell 36 on one side of the outer shell 1, the rotating rod 32 is limited when it rotates inside the limiting shell 36. When the rotating rod 32 drives the inclined block 35 inside the limiting shell 36 to move down, it guides the inclined block 35 to prevent it from tilting. The inclined block 35 squeezes the clamping block 29. The clamping block 29 is under force, and the square spring 28 makes the clamping block 25 below the second toothed plate 23 clamp more firmly. The limiting shell 36 limits the clamping block 29 to prevent the clamping block 29 from tilting and becoming unable to bear force.

[0033] Example 2 Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the outer casing 1 has a first limiting groove 12 and a second limiting groove 13 inside.

[0035] By sliding the first limiting block 21-1 and the second limiting block 23-1 within the first limiting groove 12 and the second limiting groove 13, the first limiting block 21-1 and the second limiting block 23-1 are limited and guided, preventing the first toothed plate 21 and the second toothed plate 23 from detaching from the outer shell 1.

[0036] A pressing plate 27 is fixedly connected to one end of the first toothed plate 21.

[0037] By pressing the pressing plate 27, pressing it can drive the first toothed plate 21 to mesh with the first gear 22.

[0038] The first toothed plate 21 has a first limiting block 21-1 fixedly connected to both sides, and the first limiting block 21-1 slides in the first limiting groove 12.

[0039] By setting the first limiting block 21-1 and pressing the pressing plate 27, the first limiting block 21-1 slides in the first limiting groove 12, thereby limiting and guiding the first toothed plate 21 to prevent it from detaching from the outer shell 1.

[0040] The second toothed plate 23 is fixedly connected to the two sides of the second limiting block 23-1, and the second limiting block 23-1 slides in the second limiting groove 13.

[0041] By setting the second limiting block 23-1, when the first gear 22 meshes with the second tooth plate 23, the second limiting block 23-1 slides in the second limiting groove 13, thereby limiting and guiding the second tooth plate 23 to prevent it from detaching from the outer shell 1.

[0042] The bottom of the second toothed plate 23 is fixedly connected to a connecting block 24 and slides on the surface of the outer shell 1. The bottom of the connecting block 24 is fixedly connected to a clamping block 25, and a rubber pad 26 is fixedly connected to one side of the clamping block 25.

[0043] By setting the rubber pad 26, the friction is increased when the second toothed plate 23 drives the clamping block 25 to clamp the object, making the clamping more secure and preventing slippage.

[0044] A square spring 28 is fixedly connected to one side of the second toothed plate 23, and a clamping block 29 is fixedly connected to one end of the square spring 28. The clamping block 29 is slidably connected inside the limiting shell 36.

[0045] By setting a square spring 28, when the inclined block 35 moves down, it squeezes the clamping block 29, and the square spring 28 is compressed, which increases the force on the second toothed plate 23 at the other end, making the clamping block 25 clamp more tightly, and playing a role in resetting and strengthening.

[0046] An arc-shaped plate 31 is fitted on the surface of the outer shell 1. A sliding groove 31-2 is provided inside the arc-shaped plate 31. A third limiting block 32-1 is slidably connected inside the sliding groove 31-2.

[0047] By opening the sliding groove 31-2, the arc plate 31 is rotated to make the third limiting block 32-1 slide in the sliding groove 31-2, thereby limiting the third limiting block 32-1 so that it will not disengage when rotating and can rotate and move.

[0048] An arc-shaped toothed plate 31-1 is fixedly connected to the bottom of the arc-shaped plate 31, and a second gear 32-2 is fixedly connected to the bottom of the third limiting block 32-1. The second gear 32-2 is fixedly connected to the upper end of the rotating rod 32, and the second gear 32-2 meshes with the arc-shaped toothed plate 31-1.

[0049] By setting the arc-shaped toothed plate 31-1, when the arc-shaped plate 31 is rotated, the arc-shaped toothed plate 31-1 meshes with the second gear 32-2, causing the rotating rod 32 to rotate and move.

[0050] The rotating rod 32 has a thread 32-3 fixedly connected to its surface, and a limit plate 33 is fixedly connected to the lower end of the rotating rod 32.

[0051] The thread 32-3 allows the rotating rod 32 to move when it rotates, serving as a guide. The limiting shell 36 has a threaded hole that mates with the thread 32-3.

[0052] In use, pressing the pressing plate 27 moves the first toothed plate 21, which in turn drives the first gear 22 to rotate, causing the second toothed plate 23 to move. The second toothed plate 23 then moves the clamping block 25, while the other end compresses the square spring 28.

[0053] After the hollow cup motor is placed in the desired position, the pressing plate 27 is released. The square spring 28 drives the second toothed plate 23 to reset. The second toothed plate 23 drives the first gear 22 to rotate, causing the first toothed plate 21 to move and the pressing plate 27 to reset. By rotating the arc plate 31, the arc toothed plate 31-1 rotates, driving the second gear 32-2 to rotate, which in turn drives the rotating rod 32 to rotate. The third limiting block 32-1 rotates and moves within the sliding groove 31-2. The rotating rod 32 rotates downward through the engagement of the thread 32-3 and the threaded hole, causing the inclined block 35 to press against the clamping block 29. The square spring 28 is compressed, reinforcing the second toothed plate 23 at the other end, making the clamping block 25 clamp the object more tightly and firmly.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
