[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] like Figures 1 to 8 As shown, this embodiment discloses a motor housing, including a housing body 1. A lifting ring 2 and a mounting groove 3 are provided on the upper side wall of the housing body 1. A connecting rod 4 extends downward from the lower end of the lifting ring 2. The lower end of the connecting rod 4 is pivotally connected to the bottom of the mounting groove 3, and its rotation plane is perpendicular to the bottom of the mounting groove 3. In this embodiment, when the connecting rod 4 rotates to a state perpendicular to the bottom of the mounting groove 3, the lifting ring 2 extends above the mounting groove 3 to enter the usage state. Conversely, when the connecting rod 4 rotates to a state parallel to the bottom of the mounting groove 3, the lifting ring 2 is retracted into the mounting groove 3 to reduce space occupation, making the outer packaging of the motor housing more compact, thereby improving environmental performance. To make the unfolded and retracted states of the lifting ring 2 more stable, the bottom of the mounting groove 3 is provided with a first locking mechanism for maintaining the connecting rod 4 perpendicular to the bottom of the mounting groove 3 and a second locking mechanism acting on the lifting ring 2 to maintain the connecting rod 4 parallel to the bottom of the mounting groove 3.

[0038] In this embodiment, the first locking mechanism comprises a first locking hole 5 penetrating the connecting rod 4 along the length direction of the connecting rod 4 and communicating with the central hole 22 of the hanging ring 2, a locking pin 6 slidingly penetrating the first locking hole 5, and a second locking hole 7 provided on the bottom of the mounting groove 3. When the connecting rod 4 is rotated to a position perpendicular to the bottom of the mounting groove 3, the first locking hole 5 is coaxially arranged with the second locking hole 7, and the locking pin 6 can be slidingly inserted into the second locking hole 7 in response to an external trigger to restrict the circumferential rotation of the connecting rod 4, thereby ensuring the stability of the hanging ring 2 when it is unfolded.

[0039] In order to prevent the locking pin 6 from being separated from the first locking hole 5 and facilitate the operation of the locking pin 6 by the staff, an anti-separation piece 8 is arranged at the end of the locking pin 6 close to the hanging ring 2 to prevent the locking pin 6 from being separated from the first locking hole 5. The anti-separation piece 8 is disc-shaped, and the end surface thereof is vertically arranged on the end of the locking pin 6. The width of the anti-separation piece 8 is greater than the thickness of the hanging ring 2, thereby facilitating the staff to insert and pull out the locking pin 6.

[0040] In order to facilitate the locking pin 6 to enter and exit the second locking hole 7, a hemispherical head 9 is arranged at the end of the locking pin 6 away from the hanging ring 2.

[0041] In order to realize the locking function of the second locking mechanism, the second locking mechanism comprises a locking buckle 10 arranged in the mounting groove 3. When the hanging ring 2 is rotated with the connecting rod 4 to a position parallel to the bottom of the mounting groove 3, the locking buckle 10 can be buckled on the upper surface of the hanging ring 2 to restrict the rotation of the hanging ring 2 and the connecting rod 4. An elastic piece 11 is arranged between the locking buckle 10 and the bottom of the mounting groove 3 to maintain the state that the locking buckle 10 is buckled on the hanging ring 2. The elastic piece 11 is preferably a stainless steel spring integrally arranged between the locking buckle 10 and the bottom of the mounting groove 3, and the stainless steel spring is vertically fixed to the bottom of the mounting groove 3.

[0042] In order to facilitate the locking buckle 10 to be driven away from the hanging ring 2 in the horizontal state, a driving piece 12 is arranged on the locking buckle 10 to drive the locking buckle 10 to be driven away from the hanging ring 2 in response to an external trigger to overcome the elastic force of the elastic piece 11. The driving piece 12 is in the form of a lever, and is integrally arranged on the top of the locking buckle 10, thereby facilitating the staff to apply force with the hand.

[0043] In order to improve the storage efficiency and convenience of the hanging ring 2, a guide slope 13 is provided on the upper surface of the locking buckle 10 to drive the locking buckle 10 to retreat in response to the longitudinal extrusion of the hanging ring 2.

[0044] In order to improve the stability and smoothness of the connecting rod 4 when it is turned over, a pivot shaft 14 is arranged on each side of the connecting rod 4 close to the bottom of the mounting groove 3, and the bottom of the mounting groove 3 is provided with a pivot seat 15 for the rotation of the two pivot shafts 14.

[0045] In order to improve the efficiency and convenience when the lifting ring 2 is unfolded, the bottom of the installation groove 3 is provided with a jack spring assembly 16 for jacking up the lifting ring 2, which can drive the lifting ring 2 to be upturned above the second locking mechanism when the second locking mechanism is disengaged from the lifting ring 2. Specifically, the jack spring assembly 16 includes a sliding hole 17 vertically provided at the bottom of the installation groove 3, a jacking rod 18 longitudinally slidingly provided in the sliding hole 17, a first locking ring 19 annularly provided on the outer circumferential surface of the jacking rod 18 and located at the lower end of the jacking rod 18, a second locking ring 20 annularly provided on the inner circumferential surface of the sliding hole 17 and located at the upper end of the sliding hole 17 to prevent the first locking ring 19 from disengaging from the sliding hole 17, and a compression spring 21 provided between the jacking rod 18 and the bottom of the sliding hole 17 to keep the jacking rod 18 in a jacking state.

[0046] Specific use process is as follows:

[0047] When the lifting ring 2 is used, the locking buckle 10 is first bent backward by means of the driving member 12 to overcome the elastic force of the elastic member 11 and drive the locking buckle 10 to disengage from the lifting ring 2 in the horizontal storage state, so that the compression spring 21 can jack up the lifting ring 2 through the jacking rod 18, so that the lifting ring 2 is popped up above the locking buckle 10. At this time, the driving member 12 is loosened to reset the elastic member 11 and the locking buckle 10, and then the lifting ring 2 is lifted together with the connecting rod 4 to a state perpendicular to the bottom of the installation groove 3, so that the first locking hole 5 on the connecting rod 4 is coaxially and directly opposite to the second locking hole 7 at the bottom of the installation groove 3. In this state, the locking pin 6 in the first locking hole 5 is inserted into the second locking hole 7 through the anti-disengagement member 8 to limit the circumferential rotation of the connecting rod 4 and the lifting ring 2. At this time, the lifting ring 2 together with the shell body 1 can be lifted by a lifting device. Since the hook (not shown) of the lifting device is inserted into the center hole 22 of the lifting ring 2, it can resist the anti-disengagement member 8 to prevent the locking pin 6 from moving upward, thereby avoiding the locking pin 6 from disengaging from the second locking hole 7 during use of the lifting ring 2, and further ensuring the stability of the motor shell during lifting.

[0048] When the lifting ring 2 needs to be stored, the lifting hook (not shown) of the lifting tool is first removed from the center hole 22 of the lifting ring 2, and then the locking pin 6 is lifted upward by the anti-dropping member 8 to make the locking pin 6 disengage from the second locking hole 7, thereby releasing the circumferential locking of the connecting rod 4 and the lifting ring 2. Since the length of the locking pin 6 is greater than the hole diameter of the center hole 22 of the lifting ring 2, the locking pin 6 cannot be disengaged upward from the first locking hole 5. In this state, the lifting ring 2 is pressed downward toward the direction close to the second locking mechanism, so that the lifting ring 2 is stored in the mounting groove 3. During the storage process, the lifting ring 2 touches the guide slope 13 on the locking buckle 10 and continues to be pressed downward, so that the locking buckle 10 can retreat against the elastic force of the elastic member 11, and the lifting ring 2 smoothly enters below the locking buckle 10. When the lifting ring 2 and the connecting rod 4 are turned to a state parallel to the bottom of the mounting groove 3, the locking buckle 10 can be automatically reset under the elastic force to clamp the lifting ring 2, thereby completing the storage and locking of the lifting ring 2. In this process, the lower end surface of the lifting ring 2 can push the top rod 18 into the sliding hole 17 against the elastic force of the compression spring 21, so as to store the energy of the jack spring assembly 16.
