[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-5As shown, the utility model is a ceiling fan hanger assembly with switchable usage states, the hanger assembly can be switched between a storage use state and a hanging use state, including a hanger body 1, the lower end of the hanger body 1 is connected to a hanging seat 2 which can rotate relative to the hanger body 1, a hanging locking structure 3 for locking the two with each other when the hanger assembly is in the hanging use state is provided between the hanging seat 2 and the hanger body 1, the hanging locking structure 3 includes a hanging locking portion 31 provided on the hanging seat 2 and a hanging locking piece 32 which is slidably provided on the hanger body 1 and is used to lock with the hanging locking portion 31 when the hanger assembly is in the hanging use state, a safety locking structure 4 for locking the hanging locking piece 32 relative to the hanger body 1 is provided between the hanging locking piece 32 and the hanger body 1. When the utility model needs to be hoisted for use, the staff operates the hoisting seat to rotate relative to the boom body to the hoisting use state, and then operates the hoisting locking piece to slide accordingly relative to the boom body and lock with the hoisting locking part, thereby locking the hoisting seat relative to the boom body, and then operates the safety locking structure to lock the hoisting locking piece relative to the boom body, so that the boom assembly can be locked in the hoisting use state, which has the characteristics of stable and reliable structure and convenient switching; when it needs to be stored for use, the unlocking action of the safety locking structure is operated to release the locking state of the hoisting locking piece relative to the boom body, and then the boom body is operated to flip and fold relative to the hoisting seat, which has the characteristics of convenient operation. In addition, the overall structure of the folded boom assembly is compact and the overall volume is minimized, which is convenient for storage, transportation and handling.

[0029] In other embodiments, the hoisting locking structure 3 includes a hoisting locking portion 31 provided on the boom body 1 and a hoisting locking member 32 slidably provided on the hoisting seat 2 and used to lock with the hoisting locking portion 31 when the boom assembly is in a hoisting use state, and a safety locking structure 4 is provided between the hoisting locking member 32 and the hoisting seat 2 for locking the hoisting locking member 32 relative to the boom body 1.

[0030] like Figure 1-5As shown, the boom body 1 is hollow and has an opening at the lower end, and the hoisting locking piece 32 is slidably placed inside the boom body 1; when the boom assembly is in a hoisting state, the lower end of the hoisting locking piece 32 abuts against the upper surface of the hoisting seat 2 to prevent the boom body 1 from rotating relative to the hoisting seat 2, and the hoisting locking portion 31 is formed by the upper surface of the hoisting seat 2. The utility model facilitates the smooth sliding of the hoisting locking piece to one side of the hoisting locking portion and locks with the hoisting locking portion through the outer wall of the hoisting locking piece and the inner guide of the boom body, avoiding the occurrence of misalignment and offset between the hoisting locking piece and the hoisting locking portion to affect the locking effect, thereby ensuring the reliability of the locking; in addition, the hoisting locking piece is slidably placed inside the boom body, which can make the overall appearance structure of the boom assembly more concise and neat, and can also play a certain protective role on the hoisting locking piece, prolong its service life, and reduce the cost of maintenance and replacement.

[0031] In order to facilitate locking, a reset elastic member, such as a spring, is provided between the hoisting lock member 32 and the boom body 1, which is used to press the hoisting lock member 32 to elastically reset relative to the boom body, but is not shown in the figure. When the boom body 1 is operated to rotate relative to the hanging seat 2 and switched to the hoisting use state, the reset elastic member presses the hoisting lock member 32 to slide downward relative to the boom body 1, so that the hoisting lock member 32 abuts against the upper surface of the hanging seat 2 to lock the boom body 1 and the hanging seat 2 to each other. In the case where a reset elastic member is not provided, when the boom body 1 is operated to rotate relative to the hanging seat 2 and switched to the hoisting use state, the hoisting lock member 32 may slide downward relative to the boom body 1 due to its own gravity and other factors until it abuts against the upper surface of the hanging seat 2.

[0032] Furthermore, the safety locking structure 4 is configured to lock the lifting locking member 32 relative to the lifting rod body 1 when the lifting locking member 32 is in abutment with the lifting locking portion 31. Figure 2 , 3 The safety locking structure 4 is configured to lock the lifting locking member 32 relative to the lifting rod body 1 when the lifting locking member 32 is separated and unlocked from the lifting locking portion 31, as shown in FIG. Figure 1 , 5 shown.

[0033] like Figure 1-5As shown, the safety locking structure 4 includes safety connection holes 41 which are arranged on the side wall of the boom body 1 and the side wall of the hanging locking member 32 and are aligned and connected with each other. A safety connection member 42 is inserted between the boom body 1 and the hanging locking member 32 to lock the hanging locking member 32 relative to the boom body 1. When the hanging locking member 32 is abutted against the hanging locking portion 31, the safety connection hole 41 above the hanging locking member 32 is aligned and connected with the safety connection hole 41 of the boom body 1. At this time, the safety connection member 42 can be inserted into the two safety connection holes 41 at the same time, as shown in FIG. Figure 2 , 3 When the lifting locking piece 32 is separated from the lifting locking portion 31 and unlocked, the safety connection hole 41 below the lifting locking piece 32 is aligned and connected with the safety connection hole 41 of the lifting rod body 1. At this time, the safety connection piece 42 can be inserted into the two safety connection holes 41 at the same time. Figure 1 , 5 For reliable connection, the safety connector 42 can be a connecting screw or a connecting screw or a connecting pin.

[0034] In order to provide another embodiment of the safety locking structure, the safety locking structure 4 includes a safety connection hole 41 arranged on the side wall of the boom body 1 or the lifting locking member 32 and a safety locking spring that can be elastically arranged on the lifting locking member 32 or the boom body 1 and can be inserted into the safety connection hole 41.

[0035] A guide structure is provided between the outer wall of the hoisting locking member 32 and the inner wall of the boom body 1, and the guide structure includes a guide slot provided on the outer wall of the hoisting locking member 32 or the inner wall of the boom body 1 and a guide protrusion provided on the inner wall of the boom body 1 or the outer wall of the hoisting locking member 32 and cooperating with the guide slot, which is not shown in the figure. In this embodiment, the guide slot is configured to extend in the length direction of the boom body 1 or the hoisting locking member 32, and the guide protrusion cooperates with the guide slot to guide the hoisting locking member 32, and at the same time, it can prevent the hoisting locking member 32 from rotating relative to the boom body, ensuring that the safety connection holes 41 of the boom body 1 and the hoisting locking member 32 are on the same vertical plane for easy alignment and connection.

[0036] The lifting locking structure 3 is also configured to lock the boom body 1 and the lifting seat 2 with each other when the boom assembly is in storage and use state, which can avoid the boom body and the lifting seat from rotating relative to each other during storage and other processes, causing collision and wear between the two, and facilitates transportation and storage.

[0037] like Figure 1-5As shown, in order to make the connection more stable and reliable, the hanging seat 2 includes a seat body 21, and two hanging ears 22 are symmetrically arranged on the upper surface of the seat body 21. A receiving space for inserting the lower end of the boom body 1 is formed on the upper surface of the seat body 21 and between the two hanging ears 22; each of the hanging ears 22 and the corresponding side walls of the boom body 1 are provided with connecting through holes 23 that are aligned and connected to each other, and a connecting screw 24 is passed through the connecting through holes 23 of the hanging ears 22 and the boom body 1. Among them, the hanging seat and the boom body have been connected and assembled in the factory. When installing on site, it is only necessary to operate the boom body to rotate relative to the hanging seat to the hanging state (or operate the hanging seat to rotate relative to the boom body to the hanging state), which shortens the on-site construction period and improves the on-site construction and installation efficiency.

[0038] In some embodiments, the lifting seat 2 is made of a hard material, such as iron, stainless steel, etc. The lifting ears 22 and the seat body 21 are connected by welding to form an integral structure. In order to improve the structural strength, the lifting ears 22 and the seat body 21 are vertically connected, such as Figure 1-5 In addition, the lifting ear 22 and the seat body 21 are manufactured separately, which can reduce the complexity of the mold structure and reduce the difficulty of mold opening.

[0039] like Figure 4 , 5 As shown, the connecting screw 24 is provided with a silicone sleeve 25 for contacting the inner wall of the connecting through hole 23 of the boom body 1, which can increase the damping force / friction force between the boom body and the connecting screw, and ensure the stable rotation between the boom body and the hanging seat.

[0040] like Figure 4 , 5 As shown, the corresponding part of the lifting locking piece 32 is provided with an avoidance notch 321 for avoiding the connecting screw 24, which can prevent the lifting locking piece 32 from interfering with the connecting screw 24 and affecting the locking cooperation between the lifting locking piece 32 and the lifting locking portion 31.

[0041] like Figure 3-5 As shown, in order to reduce the overall weight and lower the manufacturing cost, the lifting locking member 32 is hollow.
