[0031] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0032] Combination Figures 1 to 9 As shown, an embodiment of the present disclosure provides an air inlet assembly mounting structure for a crane, the crane comprising a shell 1, a fan cavity 2 is provided in the shell 1, a fan mounting member 3 is provided in the fan cavity 2, a fan assembly 4 is fixed in the fan cavity 2 via the fan mounting member 3, an air inlet is also provided on the shell 1, an air inlet assembly 5 is provided on the air inlet, and the air inlet assembly 5 is configured to be mountable on the fan mounting member 3 and / or the shell 1 by rotating a button 9.

[0033] The installation structure of the crane air inlet assembly of the present embodiment can realize that the air inlet assembly 5 can be fixed on the housing 1 or the fan mounting member 3 without using screws. When maintenance is required or the filter screen is tilted, it can be removed without using special tools. The air inlet assembly 5 is installed by rotating the button 9. It can be flexibly used on cranes with different housings, thereby improving the versatility of the air inlet assembly 5, saving the number of mold opening times, and reducing costs.

[0034] In some embodiments, the air inlet assembly 5 includes a first end 10 and a second end 11 that are arranged opposite to each other. The first end 10 cooperates with the housing 1 through a hook portion 12, and the second end 11 cooperates with the fan mounting member 3 through a rotating button 9.

[0035] In the floor-standing crane air conditioner product, due to the uniqueness of its internal structure, the two ends of the air inlet assembly 5 correspond to the positions of the housing 1 and the fan mounting member 3 respectively, and considering the angles of the floor-standing crane for sitting and hanging installation, the first end 10 is movably connected to the housing 1 by a hook portion 12, and the second end 11 is movably installed with the fan mounting member 3 by a rotating button 9. When installing the air inlet assembly 5, first use the hook portion 12 to connect the first end 10 to the housing 1, snap the air inlet assembly 5 on the air inlet, and then use the rotating button 9 to lock the second end 11 on the fan mounting member 3 to complete the assembly of the air inlet assembly 5. The air inlet assembly 5 no longer needs to be fixed with screws. When disassembling, just unscrew the rotating button 9 in the opposite direction to remove the air inlet assembly 5, which is convenient for operation, improves the efficiency of maintenance, cleaning or replacement of the air inlet assembly 5, and saves operating space.

[0036] In some embodiments, in order to achieve the characteristics of locking and fixing the air inlet assembly 5 to the fan mounting member 3 while having the characteristics of easy disassembly and installation, the fan mounting member 3 is provided with a first assembly groove 13, and the air inlet assembly 5 is provided with a second assembly groove 14. The positions of the first assembly groove 13 and the second assembly groove 14 correspond to each other, and the rotating button 9 passes through the second assembly groove 14 and the first assembly groove 13 in sequence to lock the air inlet assembly 5 to the fan mounting member 3. Therefore, the air inlet assembly installation structure of this embodiment is connected in the assembly grooves of the air inlet assembly 5 and the fan mounting member 3 by the rotating button 9, and the locking is completed by rotating the preset angle. When disassembling, it is only necessary to rotate the rotating button 9 in the opposite direction by the preset angle to pull it out and remove the air inlet assembly 5.

[0037] In some embodiments, in order to achieve locking by rotation, the rotating button 9 includes a knob body 15 and a first claw 16, wherein the first claw 16 is arranged on the knob body 15, and the first claw 16 is configured to be able to pass through the second assembly groove 14 and the first assembly groove 13 in sequence, and when the knob body 15 is rotated by a preset angle, the first claw 16 can be clamped on the fan mounting member 3, and at the same time, the knob body 15 can limit the external air inlet assembly 5, thereby locking the air inlet assembly 5 on the fan mounting member 3.

[0038] In some embodiments, the first claw 16 includes an eight-shaped structure extending radially outward from the knob body 15, the first assembly slot 13 includes a rectangular slot structure, and the first claw 16 is configured to be able to pass through the rectangular slot structure only at an initial angle. In this embodiment, when the rotating button 9 is at an initial angle, the opening angle of the first claw 16 is the same as the circumferential angle of the first assembly slot 13, and the first claw 16 can smoothly pass through the first assembly slot 13, but when the first claw 16 rotates by a preset angle with the rotating button 9, the end of the first claw 16 rotates out of the range of the first assembly slot 13, and the end of the first claw 16 is stuck by the fan mounting member 3 around the first assembly slot 13, and cannot be disengaged in the axial direction, thereby playing a tightening role.

[0039] In some embodiments, in order to limit the preset angle of rotation of the knob body 15 and to make the knob body 15 fit together with the air inlet assembly 5, the knob body 15 is also provided with a second claw 17, and the air inlet assembly 5 is provided with a bayonet 18. The second claw 17 is configured to be able to be circumferentially engaged with the bayonet 18 as the knob body 15 rotates. When the knob body 15 rotates to a preset angle, the second claw 17 engages with the bayonet 18 and limits the continued rotation of the knob body 15 in this direction, limiting the knob body 15 in a locked position. At the same time, through the cooperation of the second claw 17 and the bayonet 18, the cooperation between the rotating button 9 and the air inlet assembly 5 is achieved, the tightness of the cooperation between the rotating button 9 and the air inlet assembly 5 is increased, and the vibration of the air inlet assembly 5 is prevented.

[0040] In some embodiments, since the cooperation between the second claw 17 and the bayonet 18 is realized with the rotation of the rotating button 9, the second claw 17 includes an L-shaped structure arranged along the circumference of the knob body 15, the second claw 17 is arranged on the inner side surface of the knob body 15, the bayonet 18 includes a mouth-shaped structure arranged along the circumference of the knob body 15, the bayonet 18 is arranged on the inner side surface of the air inlet assembly 5, and the second claw 17 can be circumferentially engaged with the bayonet 18. In this embodiment, the inner side surface of the knob body 15 and the inner side surface of the air inlet assembly 5 are both sides facing the fan cavity of the crane, and are structural surfaces that cannot be directly observed from the outside.

[0041] In some embodiments, the knob body 15 is further provided with a raised hand-holding portion 19, so that the user can hold the rotating button 9 through the hand-holding portion 19 to rotate it; and / or, the knob body 15 is further provided with an indicator mark 20, and the indicator mark 20 includes but is not limited to a rotation direction symbol, an ON symbol, and an OFF symbol, so that the user can directly operate in the correct direction according to the prompt of the indicator mark 20, and determine that it has been rotated to the locking position based on the contact feedback of the second claw 17 and the bayonet 18.

[0042] In some embodiments, the second assembly groove 14 is a stepped hole, and the knob body 15 can be installed and limited in the second assembly groove 14. Therefore, the second assembly groove 14 provides axial limitation for the knob body 15 during assembly to prevent excessive insertion of the knob body 15. Preferably, the second assembly groove 14 includes a stepped surface 25, and the bayonet 18 is arranged on the inner side surface of the air inlet assembly 5 corresponding to the stepped surface 25. The stepped surface 25 is provided with a notch 26, and the function of the notch 26 is to facilitate the second claw 17 to pass through the second assembly groove 14 at an initial angle. As the rotating button 9 rotates, the second claw 17 can rotate from the notch 26 position to the back side of the stepped surface 25, and finally cooperate with the bayonet 18.

[0043] In some embodiments, the first assembly groove 13 is arranged on the boss 24, and the boss 24 is hollow inside to serve as a receiving space for the first claw 16. When the first claw 16 rotates, it is inside the boss 24 to avoid interference between other structures of the fan mounting component 3.

[0044] In some embodiments, in order to further prevent the rotating button 9 from falling off the crane, a first threaded structure 21 is provided on the inner wall of the second assembly groove 14, and a second threaded structure 22 is provided on the outer wall of the rotating button 9. When the rotating button 9 locks the air inlet assembly 5 on the fan mounting member 3, the first threaded structure 21 and the second threaded structure 22 are threadedly matched, and the rotating button 9 is fixed in the first assembly groove 13. The rotating button 9 can be removed only by rotating the rotating button 9 in the reverse direction.

[0045] In some embodiments, considering that the fan mounting member 3 in the related art is made of sheet metal material, which increases the difficulty of processing the first assembly groove 13, a connecting plate 23 is provided on the fan mounting member 3, and the connecting plate 23 is made of injection molding material. Preferably, the connecting plate 23 includes a main support plate, a fixing buckle, and a convex structure, and a rectangular first assembly groove 13 is provided on the convex structure. When in use, the connecting plate 23 is first installed on the fan mounting member 3 through a plurality of fixing buckles. To improve the fastening, a screw is fixed in the middle and then installed in the housing as the entire fan mounting component. The air inlet assembly 5 is movably installed on the connecting plate 23 by rotating the button 9. In other embodiments, the connecting plate 23 can also be assembled on the housing as a single part.

[0046] In some embodiments, the air intake assembly 5 includes a grille and / or a filter. When the air intake assembly 5 includes a grille and a filter, the filter is installed on the grille, and then the grille is movably installed on the crane as a whole to facilitate maintenance and cleaning of the filter.

[0047] When using the air inlet assembly installation structure of this embodiment, first align and snap the first assembly groove 13 of the air inlet assembly 5 and the second assembly groove 14 of the connecting plate 23, and insert the rotating button 9 into the two assembly grooves accordingly; according to the indication mark 20 of the rotating button 9, rotate 60° in the correct direction to make the first claw 16 and the second claw 17 staggered with the first assembly groove 13 and the notch 26 respectively; at the same time, the second thread structure 22 of the rotating button 9 is threadedly matched with the first thread structure 21 on the air inlet assembly 5 to complete the assembly of the air inlet assembly 5. When disassembling the air inlet assembly 5, rotate the rotating button 9 in the opposite direction until the first claw 16 and the second claw 17 are aligned with the first assembly groove 13 and the notch 26 respectively, and then it can be pulled out axially.

[0048] This embodiment also provides a crane that adopts the above-mentioned crane air inlet assembly installation structure.

[0049] In some embodiments, the seat hoist further includes
