Description

Technical field

[0001] The present invention relates to the technical field of ceiling fan installation, and in particular to a novel ceiling fan suspension mechanism and a ceiling fan. [Background Technology]

[0002] The existing ceiling fan suspension mechanism on the market is installed by cooperating between a hanging rod, a hanging ball and a hanger. During installation, the hanger is first fixed to the ceiling, and then the upper end of the hanging rod is passed through the hanger connecting part of the hanger, and then the hanging ball is matched with the upper end of the hanging rod through a connecting pin to achieve a relatively fixed connection between the hanging rod, the hanging ball and the hanger. In the process of achieving the connection between the hanging ball and the hanging rod, the installer needs to hold the hanging rod with one hand and hold the hanging ball with the other hand to match it with the upper end of the hanging rod. After matching, it is also necessary to take the pin through the hanging ball and the hanging rod to make the hangers relatively fixed to the hanger.

[0003] The above-mentioned suspension mechanism requires both hands to operate and cooperate during the installation process, which results in a complex and inconvenient installation. It is also very inconvenient when the user needs to disassemble and clean it later.

[0004] In view of the above technical problems, the present invention is proposed in this study. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is to provide a new type of ceiling fan suspension mechanism and ceiling fan, by arranging a left connecting arm and a right connecting arm whose tops are hinged to each other at the bottom of the mounting seat, and arranging a left clamping arm and a right clamping arm that are hinged to each other and hinged to the corresponding left connecting arm and right connecting arm, and also arranging an elastic reset member to provide pulling force to form an open clamping space at the lower ends of the left clamping arm and the right clamping arm, and arranging a hanging ear on the suspension rod, which can be hung on the left clamping arm and the right clamping arm during installation, and drive the lower ends of the left clamping arm and the right clamping arm to clamp the middle and upper part of the suspension rod, thereby solving the problem of inconvenience in installation and disassembly of existing ceiling fans.

[0006] In order to solve the above technical problems, the present invention proposes a novel ceiling fan suspension mechanism, comprising:

[0007] A mounting base, fixedly connected to the ceiling;

[0008] A symmetrically arranged left connecting arm and a right connecting arm, the tops of which are hinged to each other via a first horizontal hinge axis and are pivotally connected to the bottom of the mounting base;

[0009] A symmetrically arranged left and right clamping arms, wherein the top end of the left clamping arm is hinged to the lower end of the right connecting arm via a second horizontal hinge axis, the top end of the right clamping arm is hinged to the lower end of the left connecting arm via a third horizontal hinge axis, and the middle portions of the left and right clamping arms are hinged to each other via a fourth horizontal hinge axis;

[0010] a suspension rod, the lower end of which is connected to the fan body;

[0011] A pair of rigid hanging ears are symmetrically arranged at the upper end of the boom and can be adjusted to the desired position along the length of the boom;

[0012] an elastic reset member, the upper end of which is connected to the bottom of the mounting seat, and the lower end of which is connected to the fourth horizontal hinge axis;

[0013] in:

[0014] In the initial state, the elastic reset member provides a pulling force to rotate the left clamping arm and the right clamping arm upward around the fourth horizontal hinge axis, and the lower ends of the two clamping arms form an open clamping space;

[0015] In the working state, the hanging ears are hung on the upper parts of the left clamping arm and the right clamping arm, and the gravity of the boom drives the lower ends of the two to close and clamp the boom.

[0016] In the novel ceiling fan suspension mechanism as described above, the lower ends of the left clamping arm and the right clamping arm are both provided with clamping blocks, and the inner sides of the clamping blocks are provided with semicircular clamping grooves.

[0017] In the novel ceiling fan suspension mechanism as described above, a silicone pad is provided in the clamping groove.

[0018] In the novel ceiling fan suspension mechanism as described above, a plurality of protrusions are provided in the clamping groove, and a clamping hole for the protrusions to be embedded is formed on the suspension rod.

[0019] In the novel ceiling fan suspension mechanism as described above, the elastic reset member is a tension spring, one end of the tension spring is connected to the mounting seat, and the other end of the tension spring is connected to the fourth horizontal hinge shaft.

[0020] The novel ceiling fan suspension mechanism as described above has a hanging ear in a "J" shape.

[0021] In the novel ceiling fan suspension mechanism as described above, the surfaces of the left clamping arm and the right clamping arm that contact the hanging ears are arranged in the form of arc surfaces.

[0022] As described above, a new type of ceiling fan suspension mechanism, the left clamp arm and the right clamp arm are both composed of a straight portion and an arc portion, the lower end of the straight portion is connected to the arc portion, the upper end of the straight portion is hinged to the corresponding left connecting arm or right connecting arm, and the left clamp arm and the right clamp arm are hinged at the straight portion.

[0023] As described above, a new type of ceiling fan suspension mechanism is provided with an adjustment ring that can be slidably connected on the suspension rod, the hanging ear is fixedly connected to the adjustment ring, a plurality of connecting holes are provided on the adjustment ring, and a plurality of adjusting holes that match the connecting holes are provided along the length direction of the suspension rod. The adjusting ring is locked with the corresponding adjusting hole after passing the bolt through the connecting hole, thereby fixing the adjusting ring.

[0024] The present invention also provides a ceiling fan, comprising a ceiling fan body and the above-mentioned novel ceiling fan suspension mechanism, wherein the ceiling fan body is connected to the bottom of the suspension rod.

[0025] Compared with the prior art, the novel ceiling fan suspension mechanism and ceiling fan of the present invention have the following advantages:

[0026] 1. When installing, you only need to lift the fan and then slowly release it; when disassembling, lift it up, then separate the hanging ear from the left clamp arm and the right clamp arm, and then you can remove the hanging rod and the ceiling fan body. The whole process does not require tools for auxiliary disassembly and assembly, which is convenient and quick.

[0027] 2. When the present application is in use, part of the force exerted on the boom will act on the left clamping arm and the right clamping arm through the hanging ears, and another part will clamp the boom through the clamping parts of the left clamping arm and the right clamping arm. Under the action of gravity, the left clamping arm and the right clamping arm will continue to clamp the boom, which can prevent the boom from loosening and falling off, thereby making the fan run more stably.

[0028] 3. The position of the hanging ears of the present application can also be adjusted on the suspension rod, thereby adjusting the height of the ceiling fan body.

[Specific implementation method]

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] like Figure 1-6 As shown, the present invention includes a novel ceiling fan suspension mechanism, including a mounting base 1, a left connecting arm 2 and a right connecting arm 20, a left clamping arm 3 and a right clamping arm 4, a suspension rod 5, a pair of rigid hanging ears 6 and an elastic reset member 7, wherein:

[0039] The mounting base 1 is fixedly connected to the ceiling. The left connecting arm 2 and the right connecting arm 20 are symmetrically arranged. The tops of the left and right connecting arms 20 are hinged to each other via a first horizontal hinge axis 10 and are pivotally connected to the bottom of the mounting base 1. The left clamping arm 3 and the right clamping arm 4 are symmetrically arranged. The top of the left clamping arm 3 is hinged to the lower end of the right connecting arm 20 via a second horizontal hinge axis 11, and the top of the right clamping arm 4 is hinged to the lower end of the left connecting arm 2 via a third horizontal hinge axis 12. The middle parts of the left and right clamping arms 3 and 4 are hinged to each other via a fourth horizontal hinge axis 13. The lower end of the suspension rod 5 is connected to the ceiling fan body 8. The hanging ears 6 are symmetrically arranged at the upper end of the suspension rod 5 and can be adjusted to a desired position along the length of the suspension rod 5. The upper end of the elastic return member 7 is connected to the bottom of the mounting base 1, and the lower end is connected to the fourth horizontal hinge axis 13. The elastic return member 7 is a tension spring, one end of which is connected to the mounting base 1 and the other end is connected to the fourth horizontal hinge axis 13.

[0040] In the initial state, the elastic reset member 7 provides a pulling force to rotate the left clamping arm 3 and the right clamping arm 4 upward around the fourth horizontal hinge axis 13, and the lower ends of the two arms form an open clamping space 9;

[0041] In the working state, the hanging ears 6 are hung on the upper parts of the left clamping arm 3 and the right clamping arm 4, and the gravity of the suspension rod 5 drives the lower ends of the two to close and clamp the suspension rod 5.

[0042] In the present application, when installing the ceiling fan, the staff will lift the fan, align the hanging ear 6 with the upper part of the left clamp arm 3 and the right clamp arm 4, overlap them and slowly release them. The hanging ear 6 will act on the left clamp arm 3 and the right clamp arm 4 at the same time, and the lower ends of the left clamp arm 3 and the right clamp arm 4 will slowly close until they are tightly holding the hanging rod 5. After holding the hanging rod 5, the hanging ear 6 will stop sliding on the left clamp arm 3 and the right clamp arm 4, thereby fixing the entire ceiling fan body 8.

[0043] During disassembly, by slowly lifting the ceiling fan body 8, under the action of the elastic reset member 7, the elastic reset member 7 provides a pulling force to rotate the left clamping arm 3 and the right clamping arm 4 around the fourth horizontal hinge axis 13, and the lower ends of the two are slowly separated to form an open clamping space 9. Continue to lift up, and the hanging ear 6 will be separated from the upper part of the left clamping arm 3 and the right clamping arm 4. Then, the hanging ear 6 is moved away from the left clamping arm 3 and the right clamping arm 4, and the entire ceiling fan body 8 and the suspension rod 5 can be disassembled.

[0044] When installing the present application, it is only necessary to lift the fan and then slowly release it; when disassembling, it is lifted up, and then the hanging ear 6 is separated from the left clamping arm 3 and the right clamping arm 4, and then the suspension rod 5 and the ceiling fan body 8 can be removed. The whole process does not require tools for auxiliary disassembly and assembly, which is convenient and fast. It is particularly suitable for situations where the ceiling fan needs to be tested inside the factory and needs to be frequently disassembled and replaced. At the same time, it is also convenient for users to disassemble and assemble it later for cleaning and maintenance. In addition, when the present application is in use, part of the force applied to the suspension rod 5 will act on the left clamping arm 3 and the right clamping arm 4 through the hanging ear 6, and another part will clamp the suspension rod 5 through the clamping part of the left clamping arm 3 and the right clamping arm 4. Under the action of gravity, the left clamping arm 3 and the right clamping arm 4 will continue to hold the suspension rod 5, which can prevent the suspension rod 5 from loosening and falling off, thereby making the fan run more stably. In addition, the hanging ear 6 of the present application can also be adjusted on the suspension rod 5, thereby adjusting the height of the ceiling fan body 8.

[0045] like Figure 1 and Figure 2 As shown, as a further solution of this embodiment, a clamping block 30 is provided at the lower end of each of the left and right clamping arms 3 and 4, and a semicircular clamping groove 31 is provided on the inner side of the clamping block 30. In this embodiment, by providing the clamping blocks 30 on both the left and right clamping arms 3 and 4, and providing the semicircular clamping groove 31 on the inner side of the clamping blocks 30, the boom 5 can be clamped during operation, which can be more stable. At the same time, a silicone pad 32 is provided in the clamping groove 31 to further prevent loosening, provide a more stable clamping, and prevent abnormal noise during use.

[0046] like Figure 1 and Figure 4 As shown, further, a plurality of protrusions 310 are provided in the clamping groove 31, and a locking hole 311 is formed on the suspension rod 5 for the protrusions 310 to be inserted into. By providing the protrusions 310 and the locking holes 311 to cooperate with each other, after the clamping block 30 is tightly clamped to the suspension rod 5, the protrusions 310 can be inserted into the locking holes 311, thereby preventing the suspension rod 5 from rotating in the clamping block 30.

[0047] like Figure 1 and Figure 2 As shown, as a further solution of this embodiment, the hanging ear 6 is in a "J" shape, and the surfaces of the left clamping arm 3 and the right clamping arm 4 that contact the hanging ear 6 are arranged in an arc surface. The hanging ear 6 is arranged in a "J" shape and can be hung on the left clamping arm 3 and the right clamping arm 4 to prevent it from falling off. At the same time, the left clamping arm 3 and the right clamping arm 4 are arranged to have an arc surface corresponding to the inner side of the hanging ear 6. In this way, when installing, the hanging ear 6 can slide down on the left clamping arm 3 and the right clamping arm 4 more smoothly, which is convenient for installation.

[0048] like Figure 2As shown, as a further solution of this embodiment, the left clamp arm 3 and the right clamp arm 4 are both composed of a straight portion 33 and a curved portion 34. The lower end of the straight portion 33 is connected to the curved portion 34, and the upper end of the straight portion 33 is hinged to the corresponding left connecting arm 2 or right connecting arm 20. The left clamp arm 3 and the right clamp arm 4 are hinged at the straight portion 33. The straight portion 33 and the curved portion 34 are integrally formed. The hanging ears 6 are then hung on the straight portions 33 of the left clamp arm 3 and the right clamp arm 4, and the curved portion forms a clamping space 9 for accommodating the boom 5. Under the action of the hanging ears 6, the boom 5 is clamped. The integral molding of the straight portion 33 and the curved portion 34 can make its supporting strength greater.

[0049] like Figure 5 、 Figure 6 As a further embodiment of this embodiment, the suspension rod 5 is provided with an adjustment ring 50 that can be slidably connected thereto. The hanging ear 6 is fixedly connected to the adjustment ring 50. The adjustment ring 50 is provided with a plurality of connection holes 51. The suspension rod 5 is provided with a plurality of adjustment holes 52 along its length that match the connection holes 51. The adjustment ring 50 is fixed by bolts passing through the connection holes 51 and then locked with the corresponding adjustment holes 52, thereby fixing the adjustment ring 50. By setting the adjustment ring 50 in different positions, the height of the hanging ear 6 can be adjusted, and thus the height of the ceiling fan body 8 can be adjusted to suit different scenarios.

[0050] like Figure 3 As shown, the present application also provides a ceiling fan, including a ceiling fan body 8, and also including a ceiling fan suspension mechanism using the present application, wherein the ceiling fan body 8 is connected to the bottom of the suspension rod 5. By using the ceiling fan suspension mechanism of the present application, it can be easily installed and disassembled, which is convenient for users to install.
