Description

Technical Field

[0001] The utility model relates to the field of ceiling fan accessories, in particular to a blade fork structure that can be quickly assembled and disassembled. Background Art

[0002] As a common ventilation and cooling device in homes and commercial places, the installation and maintenance process of ceiling fans involves a series of technical details, especially the connection and fixing methods between the motor, mounting plate and fan blades. In the early stage of ceiling fan installation, the first step is to firmly hang the mounting plate with integrated motor on the roof ceiling. This step ensures the solid foundation of the entire ceiling fan system. Subsequently, the installation of fan blades becomes a key link, which requires each fan blade to be precisely fixed on the blade fork with screws, and then the blade fork is aligned with the preset position on the mounting plate for assembly.

[0003] During this process, the installer needs to keep his head up for a long time, stretch his arms upward, and use tools such as screwdrivers to tighten the screws one by one to ensure a tight connection between the inner end of the Yaksha and the mounting plate. However, this operation method is not only laborious and cumbersome, but also poses a great challenge to the installer's physical strength and patience. In addition, due to the limited operating space and obstructed vision, the degree of screw tightening is prone to improper conditions, and over-tightening or over-loosening may affect the stability of the ceiling fan. After long-term use, the traditional screw fixing method also faces the problem of loosening. The centrifugal force generated by the high-speed rotation of the ceiling fan and the vibration of daily use will gradually cause the screws to loosen, which in turn causes the instability of the fan blades. This instability will not only increase the noise of the ceiling fan during operation, such as vibration or friction, and reduce the user's comfort, but may also cause more serious safety problems, such as the fan blades falling off during high-speed rotation, posing a threat to surrounding people or objects. In addition, the instability of the fan blades will also aggravate the wear of the internal structure of the ceiling fan, especially the motor, bearings and connection parts, shortening their service life and increasing maintenance costs.

[0004] In summary, the installation and maintenance process of ceiling fans, especially the fixing method between the blade fork and the mounting plate, is a critical and challenging link. It requires installers to have professional skills and patience, and also reveals the shortcomings of the existing fixing method in long-term use, including the cumbersome installation process, stability problems caused by the loosening of screws, and potential impact on the overall performance and life of the ceiling fan. Therefore, the existing blade fork disassembly and assembly structure of ceiling fans needs to be further optimized and improved. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: Figures 1 to 8 The blade fork structure shown in the figure can be quickly assembled and disassembled, including a mounting base 1 with a plurality of sockets 11 evenly spaced on the circumferential outer wall, each socket 11 is provided with a corresponding slot 12, and one side of the slot 12 is open, which is convenient for the insertion and fixation of the blade fork 2. A guide groove 13 is also provided on the top inner wall of the slot 12, and the guide groove 13 extends along the insertion direction of the blade fork 2, and the outer end penetrates to the socket 11, which is used to guide the accurate insertion of the blade fork 2. A card slot 21 is provided on the edge of one side of the blade fork 2 inserted into the slot 12, and the side with the card slot 21 can be exposed outside the opening of the slot 12 after being inserted into the slot 12. The card slot 21 adopts a concave "V"-shaped structure, and its internal angle is greater than 90 degrees. At the same time, a guide convex strip 22 protruding upward is also provided on the surface of the inner end of the blade fork 2, and the guide convex strip 22 can be accurately inserted into the guide groove 13 on the mounting base 1 to ensure the accurate installation of the blade fork 2. A limiting block 33 and a reversible latch 3 are provided on the mounting base 1 on one side of the opening of each slot 12, and a reset member 4, specifically a reset spring 43, is provided on the latch 3. When the latch 3 is unlocked, the reset spring 43 can push one side of the latch 3 to remain against the limiting block 33, and the end of the latch 3 away from the hinge is obliquely pointed to the slot 21, that is, when the inner end of the blade fork 2 is fully inserted into the slot 12, the state of the latch 3 is that one side is pressed by the limiting block 33, and the end is stuck in the slot 21, so as to achieve the locking of the blade fork 2. In this way, the pointing angle of the latch 3 in the locked state forms an acute angle with the insertion direction of the blade fork 2, which effectively prevents the blade fork 2 from being pulled out by centrifugal force.

[0034] Further, the locking member 3 is composed of a swing arm 30 and a pillar 32. One end of the swing arm 30 is rotatably hinged to the mounting base 1 through a swing shaft 31, and the other end is connected to the pillar 32. The swing arm 30 is designed to form an acute angle with the extension line of the insertion direction of the leaf fork 2, so that when the leaf fork 2 is inserted, the swing arm 30 can be automatically pushed to flip, and the circumferential outer wall of the pillar 32 is pressed into the card slot 21 to achieve locking. A spring groove 41 is provided on the swing arm 30. One end of the return spring 43 is inserted into the spring groove 41, and the other end abuts against the stopper 42 protruding from the mounting base 1. When the locking member 3 is unlocked, the return spring 43 can push the swing arm 30 to automatically return to the initial position.

[0035] Among them, in order to ensure that the locking member 3 will not be accidentally unlocked when locking the leaf fork 2, as Figures 2 to 8 shown. A locking member 5 is provided on the pillar 32. The locking member 5 includes a ball slot 51 provided in the pillar 32. One end of the ball slot 51 facing the surface of the mounting base 1 is open, and a ball 52 is movably provided inside. A pressing spring 53 is provided at the tail end of the ball 52 for keeping the hemispherical head end of the ball 52 protruding from the opening of the ball slot 51. A positioning hole 56 corresponding to the head end of the ball 52 is provided on the surface of the mounting base 1. When the locking member 3 is flipped and snapped into the card slot 21 to lock the leaf fork 2, the head end of the ball 52 is inserted into the positioning hole 56 to prevent the locking member 3 from flipping out of the card slot 21 again. To ensure that the ball 52 can move up and down stably in the ball slot 51, a contact boss 55 is further provided on the circumferential inner wall of the ball slot 51 near the opening position, and an annular boss 54 is provided on the circumferential outer wall of the ball 52. When the head end of the ball 52 protrudes from the opening of the ball slot 51, the contact boss 55 will abut against the annular boss 54 together. One end of the pressing spring 53 abuts against the annular boss 54 and the other end abuts against the tail end of the ball slot 51.

[0036] In addition, as Figures 1 to 8 shown, for the convenience of the user to operate the locking member 3, a handle 6 is provided at one end of the pillar 32 away from the surface of the mounting base 1. The handle 6 includes a convex column 60 extending from one end of the pillar 32 away from the surface of the mounting base 1. A bolt 61 is connected to the end of the convex column 60. A rotatable annular sleeve 62 is sleeved on the bolt 61. When the user needs to unlock the locking state of the leaf fork by the locking member 3, the user can flip the swing arm 30 by the handle 6 with one hand, so that the pillar 32 moves out of the card slot 21 along an arc path.

[0037] It should also be noted that, on the one hand, in this embodiment, in order to increase the contact area between the abutment pillar 32 and the card slot 21 and improve the locking stability, and on the other hand, in order to make it smoother when operating the swing arm 30 to turn over and let the abutment pillar 32 disengage from the card slot 21, without the outer wall of the abutment pillar 32 being stuck by the card slot 21 and preventing the abutment pillar 32 from moving out of the card slot 21 along an arc path, the inner included angle of the "V"-shaped structure of the card slot 21 is greater than 90 degrees.

[0038] Through the above embodiments, the rapid installation and disassembly of the blade fork are realized, the installation efficiency is significantly improved, and the installation difficulty is reduced. At the same time, the locking mechanism of the locking part and the card slot ensures the stability of the blade fork during the operation of the ceiling fan, reduces the risks of noise, vibration and blade detachment caused by screw loosening, provides a safer, more reliable and more convenient solution for the long-term use of the ceiling fan, and improves the user experience.
