Description

Technical Field

[0001] The utility model relates to the field of ceiling fans, in particular to a suspension mechanism for quick installation without a hanging ball.

Background Art

[0002] Ceiling fans are common electrical appliances. Ceiling fans are widely used in families and enterprises due to their advantages of large air volume, wide coverage, good air fluidity, high human comfort, no occupation of floor space, long service life, and energy saving.

[0003] At present, the existing ceiling fan suspension mechanisms on the market are installed by the cooperation among a suspension rod, a hanging ball, and a hanger. During installation, the hanger is first fixed to the ceiling, then the upper end of the suspension rod passes through the suspension rod connection part of the hanger, and then the hanging ball is cooperatively connected with the upper end of the suspension rod through a connecting pin, so as to realize the relatively fixed connection among the suspension rod, the hanging ball, and the hanger. In the process of realizing the cooperation connection between the hanging ball and the suspension rod, the installer needs to hold the suspension rod with one hand, and at the same time, hold the hanging ball with the other hand to cooperate with the upper end of the suspension rod. After cooperation, a pin still needs to be passed through the hanging ball and the suspension rod to make the hanger and the suspension rod relatively fixed.

[0004] Using the above suspension mechanism, the installation process requires the cooperation of both hands, which has the problems of complex and inconvenient installation, and high manufacturing cost due to many components.

The suspension rod and the hanger of the suspension mechanism can realize that the upper end of the suspension rod passes through from below the hanger to above the hanger and cooperates with the suspension rod installation part through one-handed operation, and then rotate the suspension rod so that the blocking mechanism prevents the suspension rod and the hanger from axially separating and relatively rotating, and can fix the hanger and the suspension rod. It has the characteristics of convenient, labor-saving, safe and reliable installation operation. In addition, the utility model reduces the hanging ball and pin parts, which saves production costs for ceiling fan manufacturers.

Detailed Embodiments

[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached Figure 1-6 , as follows:

[0028] As Figure 1-6 shown, a quick-installation hanging mechanism without a hanging ball of the utility model includes a hanging rod 1 and a hanging bracket 2. The hanging bracket 2 is relatively fixedly connected to the ceiling. A hanging rod installation part 20 for the hanging rod 1 to pass through and connect is provided on the hanging bracket 2. The upper end of the hanging rod 1 is passed from below the hanging bracket 2 to above the hanging bracket 2. A blocking mechanism 3 is provided between the hanging rod 1 and the hanging bracket 2. The blocking mechanism 3 is configured to: when the upper end of the hanging rod 1 passes through the hanging rod installation part 20 and extends and rotates a preset angle, the blocking mechanism 3 will prevent the hanging rod 1 and the hanging bracket 2 from separating axially, and limit the rotation of the hanging rod 1 relative to the hanging bracket 2. The hanging rod and the hanging bracket of the utility model are directly relatively fixed through the blocking mechanism, thus eliminating the need for a traditional hanging ball and a plug pin to install and fix between the hanging rod and the hanging bracket, saving parts and reducing the production cost; in addition, during the installation process of the utility model, only one hand operation is required to perform the fitting and fixing operation, which has the characteristics of convenient and reliable connection.

[0029] On this basis, the following embodiments 1 to 4 are provided for further description:

[0030] Example 1:

[0031] If Figure 3 As shown, the boom mounting portion 20 includes a through hole 21 that allows the upper end of the boom 1 to pass through and a support wall 22 that extends upward along the edge of the through hole 21. The edge of the through hole 21 is provided with a notch 211 for avoiding the upper end of the boom 1 to pass through. The blocking mechanism 3 includes a limiting protrusion 13 and a limiting bayonet 23 that are engaged with each other. The limiting protrusion 13 is provided on the boom 1, and the limiting bayonet 23 is correspondingly provided on the support wall 22. When the through hole 21 is provided on the upper end of the boom 1, the limiting protrusion 13 passes through the notch 211 accordingly, and the limiting bayonet 23 deviates from the notch 211 and is provided on the support wall 22. The limiting protrusion 13 and the limiting bayonet 23 are respectively two in number and are respectively on a diameter line.

[0032] The limiting protrusion 13 is arranged to protrude from the upper side of the suspension rod 1 and is integrally formed with the suspension rod 1 by stamping. The limiting protrusion 13 has a first side 131 and a second side 132 respectively used to abut against the two side surfaces of the limiting bayonet 23, and the first side 131 and the second side 132 are connected to form a V-shaped structure. The limiting protrusion 13 abuts against the limiting bayonet 23, and the two side surfaces of the limiting bayonet 23 abut against the first side 131 and the second side 132 of the limiting protrusion 13, thereby limiting the rotation of the suspension rod 1 and the hanger 2. Preferably, the utility model adopts the first embodiment with lower production cost.

[0033] Example 2:

[0034] If Figure 4 As shown, the difference from the first embodiment is that the limiting protrusion 13 is a pin connected transversely to the upper end of the suspension rod 1, and the pin can be inserted into the insertion hole of the suspension rod 1 before or after the suspension rod mounting portion 20 connected to the suspension rod 1 is inserted.

[0035] Example 3:

[0036] If Figure 5 As shown, the difference from the first embodiment is that the limiting protrusion 13 is an elastically retractable spring bean structure, and the spring bean structure includes a spring bean placed on the suspension rod 1 and a socket provided on the suspension rod 1 to allow the spring bean to retract and pass through.

[0037] Example 4: As Figure 6 ​As shown in the figure, a way is provided in which the positions where the limiting protrusion 13 and the limiting bayonet 23 are provided are different from those in the first to third embodiments. The hanger rod mounting portion 20 includes a through hole 21 allowing the upper end of the hanger rod 1 to pass through and a support wall 22 extending upward along the edge of the through hole 21. The blocking mechanism 3 includes a limiting protrusion 13 and a limiting bayonet 23 that are engaged with each other. The limiting protrusion 13 is elastically telescopic and provided on the support wall 22 and protrudes from the inner side surface of the support wall 22. Correspondingly, the limiting bayonet 23 is provided on the side surface of the upper end of the hanger rod 1.

[0038] As Figure 1-6 shown, further, on the basis of the above embodiment, the support wall 22 is formed by flanging when stamping the through hole 21 by a stamping process, which can reduce the production steps of the product and lower the production cost.

[0039] Furthermore, in order to further fix the hanger rod 1 after it is fitted with the hanger, a threaded connection hole 14 is provided at the upper end portion of the hanger rod 1. A positioning hole 24 corresponding to the threaded connection hole 14 is provided on the support wall 22. The hanger rod 1 and the hanger 2 are fixedly connected to each other relatively through a connecting member 4 between the threaded connection hole 14 and the positioning hole 24. The connecting member is a bolt.

[0040] The positioning hole 24 is offset relative to the limiting bayonet 23, and the positioning hole 24 and the limiting bayonet 23 are not on the same vertical line. Such a setting makes the structure simpler and the production and installation of the present utility model more convenient.
