Specifically, the number of the roller assemblies 200 is four, two of the roller assemblies 200 are disposed at one end of the base plate 110, and the other two roller assemblies 200 are disposed at the other end of the base plate 110. Accordingly, the base plate 110 is configured with four mounting holes 112, and the four mounting holes 112 are respectively installed for the mounting shafts 212 of the four roller assemblies 200.

The technical scheme of the utility model, through construct location portion 213 on the installation axle 212 at roller bracket 210, this location portion 213 is the non-circular setting to the bottom plate 110 lower surface on chassis 100 is constructed with the constant head tank 151 with location portion 213 adaptation, thereby after installation axle 212 is good with mounting hole 112, installs the epaxial location portion 213 of axle 212 and spacing in constant head tank 151. When the gyro wheel takes place to roll, wheel support 210 has the rotatory trend of relative mounting hole 112, but because wheel support 210's the epaxial location portion 213 of installation axle 212 is the non-circular setting, location portion 213 is injectd and is difficult for taking place rotary motion in constant head tank 151, thereby make wheel support 210's installation axle 212 be difficult to take place rotatoryly, avoid installation axle 212 to take place rotatoryly and skid relative mounting hole 112, effectively improve the stability that wheel support 210 and chassis 100 of rolling subassembly are connected, the condition that wheel support 210 takes place to skid has been reduced and has appeared, and then ensure that the gyro wheel passes through wheel support 210 and stably drives air conditioner moving as a whole.

Referring to fig. 5 to 7, in an embodiment, a supporting portion 214 is further formed at an end of the mounting shaft 212 close to the mounting seat 211, and a positioning portion 213 is formed on an upper side surface of the supporting portion 214 of the mounting shaft 212; the lower surface of the bottom plate 110 is convexly provided with a supporting boss 150 for the supporting portion 214 to abut against, and the central portion of the supporting boss 150 is concavely formed with a positioning groove 151 to correspond to the positioning portion 213.

As shown in fig. 7 and 8, the positioning portion 213 is located on the upper surface of the supporting portion 214, and after the mounting shaft 212 is assembled with the mounting hole 112, the upper surface of the supporting portion 214 abuts against the supporting boss 150 to strongly support the chassis 100; meanwhile, the positioning part 213 is just inserted into the position limiting groove at the center of the supporting boss 150. Since the support boss 150 is located at a position around the mounting hole 112, the support boss 150 can enhance the strength of the position around the mounting hole 112, and the periphery of the mounting hole 112 is not easily broken, so that the mounting shaft 212 is more firmly mounted in the mounting hole 112.

Further, in the radial direction of the mounting shaft 212, the maximum height of the positioning portion 213 protruding from the outer surface of the mounting shaft 212 is preferably larger than the height of the support portion 214 protruding from the outer surface of the mounting shaft 212, so that the support portion 214 has a supporting surface for supporting the chassis 100, and the support portion 214 has a large strength, and can stably support the chassis 100.

Referring to fig. 3 and 4, in an embodiment, the lower surface of the bottom plate 110 is configured with a first retaining ring 113 disposed annularly, and the first retaining ring 113 surrounds the circumference of the supporting boss 150. When the mounting shaft 212 of the roller bracket 210 is fixedly connected to the mounting hole 112, the first baffle ring 113 surrounds the support boss 150 and the lower end of the mounting shaft 212, and the first baffle ring 113 can block water around the mounting shaft 212, so as to prevent the water from flowing between the mounting shaft 212 and the mounting hole 112 and prevent the mounting shaft 212 from being rusted. Moreover, the first baffle ring 113 can also strengthen the strength of the periphery of the mounting hole 112, so that the periphery of the mounting hole 112 is not easy to break, the stability of connection between the mounting hole 112 and the mounting shaft 212 is improved, and the roller assembly 200 is ensured to be stably mounted.

Alternatively, a plurality of support ribs 152 may be formed on the circumferential portion of the support boss 150, the ends of the plurality of support ribs 152 are connected to the first baffle ring 113, and a groove 153 is formed between two adjacent support ribs 152. The plurality of support ribs 152 may not only increase the strength of the support boss 150, but also enhance the strength of the first baffle ring 113, so that the support boss and the first baffle ring 113 are not easily damaged.

Further, the lower surface of the bottom plate 110 is configured with a plurality of transverse ribs and longitudinal ribs arranged in a criss-cross manner; the outer peripheral surface of the first baffle ring 113 is configured with a fixing rib 117, one end of the fixing rib 117 is connected with the first baffle ring 113, and the other end of the fixing rib 117 is connected with the transverse rib or the longitudinal rib. That is, the outer circumferential surface of the first baffle ring 113 is connected to the transverse ribs or the longitudinal ribs of the base plate 110 via the plurality of fixing ribs 117, so that the strength and firmness of the first baffle ring 113 can be enhanced, and the first baffle ring is not easily broken by collision.

Referring to fig. 1 and 2, in an embodiment, the upper surface of the bottom plate 110 is further configured with a second retaining ring 114 disposed annularly, and the second retaining ring 114 surrounds the periphery of the upper periphery of the mounting hole 112. Specifically, when the mounting shaft 212 of the roller bracket 210 is fixedly coupled to the mounting hole 112, the second retaining ring 114 surrounds the upper end of the mounting shaft 212 and the nut 103 fitted around the upper end of the mounting shaft, and the second retaining ring 114 can block water around the mounting shaft 212 to prevent the water from flowing between the mounting shaft 212 and the mounting hole 112 to prevent the mounting shaft 212 from rusting. Moreover, the second retainer 114 can also reinforce the strength of the surrounding portion of the mounting hole 112, so that the surrounding portion of the mounting hole 112 is not easily broken, the stability of the connection between the mounting hole 112 and the mounting shaft 212 is improved, and the stable mounting of the roller assembly 200 is ensured. In addition, the first baffle ring 113 can also separate the mounting shaft 212 from other components on the upper surface of the chassis 100, so that other components on the chassis 100 are prevented from contacting and colliding with the mounting shaft 212 in the assembling process or the dropping experiment, and the occurrence of the situation that the mounting shaft 212 is broken by collision is reduced.

According to any of the above embodiments, the air conditioner further includes a housing mounted on the base pan 100; the side plate 120 of the chassis 100 is formed with a plurality of coupling holes 121, and the coupling holes 121 are adapted to allow coupling members to pass therethrough to be coupled to the housing. The attachment means may be a screw.
