[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] A swimming pool vacuum cleaner is a device used to vacuum and clean the bottom and walls of a swimming pool. Its wheels are directly set on the bottom shell through fasteners such as screws, and there is no movement between the wheels and the bottom shell. As a result, when the swimming pool vacuum cleaner passes through an uneven road surface or encounters obstacles, it has poor shock absorption and poor stability, and its obstacle-crossing ability is also poor.

[0041] In view of this, the utility model provides a wheel mechanism, which includes a bottom shell 100 and a rolling assembly 200, wherein the rolling assembly 200 includes a wheel 210 and a bracket 220; wherein the wheel 210 and the bracket 220 are rotatably matched; the bracket 220 is slidably connected to the bottom shell 100, and the sliding path is along the radial direction of the wheel 210 and perpendicular to the travel direction of the wheel 210; a limiting structure is provided between the bracket 220 and the bottom shell 100, and the limiting structure is configured to limit the bracket 220 from detaching from the bottom shell 100 under sliding conditions.

[0042] In the wheel mechanism, the wheel 210 and the bracket 220 are rotationally matched, the bracket 220 is slidably connected to the bottom shell 100, and the sliding path is along the radial direction of the wheel 210 and perpendicular to the travel direction of the wheel 210. In this way, when the wheel 210 moves, the bracket 220 can slide up or down, thereby driving the wheel 210 to move up and down, so that there is a movable amount between the wheel 210 and the bottom shell 100; the limiting structure is arranged between the bracket 220 and the bottom shell 100, preventing the bracket 220 from being separated from the bottom shell 100, that is, ensuring the stability of the connection between the wheel 210 and the bottom shell 100. In application, when the swimming pool suction machine passes through an uneven road surface or encounters an obstacle, the wheel 210 can slide downward or upward through the bracket 220 to pass through a concave road surface or a convex road surface.

[0043] It can be seen that compared with the prior art, the wheel mechanism enables the wheel 210 to move up and down through the bracket 220, even if there is mobility between the wheel 210 and the bottom shell 100, thereby improving the obstacle crossing ability, while also improving the shock absorption, ensuring the stability of the swimming pool vacuum cleaner during operation.

[0044] The following combination Figures 1 to 5 The structure and shape of the wheel mechanism provided in this embodiment are described in detail:

[0045] For further reference, Figures 1 to 5 The bottom shell 100 is provided with a mounting hole; the bracket 220 includes a sliding section 221, which passes through the mounting hole and can slide along the axial direction of the mounting hole.

[0046] Continue to refer Figures 1 to 5 The bracket 220 also includes a fixing seat 223; one end of the sliding section 221 is fixedly connected to the top surface of the fixing seat 223, and the other end extends upward; the wheel 210 is rotatably connected to the fixing seat 223 via a rotating shaft. When passing through an uneven road surface, the wheel 210 moves downward or upward, and drives the sliding section 221 to slide downward or upward along the mounting hole through the fixing seat 223. Such a design ensures that there is an upward and downward movement between the wheel 210 and the bottom shell 100, while ensuring the stability of the wheel 210 when moving.

[0047] Regarding the limiting structure, specifically:

[0048] refer to Figure 2 and Figure 3 The limiting structure includes a limiting groove 222 and a limiting member, which is plugged into the limiting groove 222 and can slide a preset distance along the axial direction of the mounting hole under the plug-in condition; one of the limiting groove 222 and the limiting member is set on the sliding section 221, and the other is set on the bottom shell 100.

[0049] Continue to refer Figure 2 and Figure 3 In one embodiment of the present application, the limiting groove 222 is provided on the sliding section 221, and the limiting member is provided on the bottom shell 100. Specifically, the sliding section 221 is columnar, the limiting groove 222 is provided on the side of the sliding section 221, the limiting member is inserted into the limiting groove 222, and can move up and down relative to the sliding section 221.

[0050] When the wheel 210 moves downward, the sliding section 221 slides downward synchronously, and the position-limiting member moves upward relative to the sliding section 221; when the wheel 210 moves upward, the sliding section 221 slides upward synchronously, and the position-limiting member moves downward relative to the sliding section 221. Figure 3As shown, the length of the limiting groove 222 in the up and down direction determines the movable distance of the limiting member, that is, determines the amount of movement between the wheel 210 and the bottom shell 100 .

[0051] In other embodiments, the limiting groove 222 may be disposed on the bottom shell 100 , and correspondingly, the limiting member may be disposed on the sliding section 221 , which may also achieve the above-mentioned effect, which will not be elaborated herein.

[0052] Regarding the limiter, specifically:

[0053] In one embodiment of the present application, reference Figures 2 to 4 The limiting member includes an elastic hook 110 , and the elastic hook 110 has a tendency to move in a direction perpendicular to the axial direction of the sliding section 221 and toward the sliding section 221 .

[0054] Specific, combined Figure 2 As shown, the upper end of the elastic hook 110 has a tendency to move leftward. When the sliding section 221 slides to the limiting groove 222 and is opposite to the upper end, the upper end will be automatically inserted into the limiting groove 222, thereby realizing the connection between the bracket 220 and the bottom shell 100.

[0055] In other embodiments, the limiting member includes a screw, which is threadedly connected to the bottom shell 100. The screw can be screwed into or out of the limiting groove 222 by rotating it, thereby facilitating the installation of the bracket 220. As mentioned above, when the screw is inserted into the limiting groove 222, it can also slide between the top wall and the bottom wall of the limiting groove 222 relative to the sliding section 221.

[0056] For further reference, Figures 2 to 4 , the end of the sliding section 221 away from the wheel 210 is chamfered; the elastic hook 110 includes an elastic connecting section 111, the elastic connecting section 111 is spaced apart from the mounting hole, and a protrusion 112 is formed on the side protruding near the mounting hole; the protrusion 112 is used to be plugged into and matched with the limiting groove 222, and its bottom surface is an inclined surface 1121, and the inclined surface 1121 is inclined from the elastic connecting section 111 to the side of the protrusion 112 away from the elastic connecting section 111 in a direction away from the wheel 210.

[0057] Specifically, Figure 2 For example, during assembly, the sliding section 221 is inserted into the mounting hole from bottom to top. When the sliding section 221 slides to its upper end and contacts the inclined surface 1121, the protrusion 112 moves to the right and drives the elastic connecting section 111 to bend, so that the sliding section 221 can continue to slide upward. When it slides to the limit groove 222 and the protrusion 112 is opposite, under the action of the restoring force of the elastic connecting section 111, the protrusion 112 moves to the left and is inserted into the limit groove 222. At this point, the installation of the bracket 220 is completed.

[0058] refer to Figures 1 to 5The wheel mechanism provided by the embodiment of the utility model includes a bottom shell 100 and a rolling assembly 200, and the rolling assembly 200 includes a wheel 210 and a bracket 220; wherein the bracket 220 includes a fixed seat 223 and a sliding section 221 vertically connected to the top surface of the fixed seat 223, the fixed seat 223 and the wheel 210 are rotatably matched, the sliding section 221 is penetrated through the mounting hole on the bottom shell 100, and a limiting groove 222 is provided on the side of the sliding section 221, and an elastic hook 110 is provided on the bottom shell 100; the elastic hook 110 includes an elastic connecting section 111, the elastic connecting section 111 is spaced apart from the mounting hole, and a protruding portion 112 is formed on the side thereof close to the mounting hole, the protruding portion 112 is plugged into the limiting groove 222, and its bottom surface is an inclined surface 1121, and the inclined surface 1121 is inclined from the elastic connecting section 111 to the side of the protruding portion 112 away from the elastic connecting section 111 in a direction away from the wheel 210.

[0059] In the wheel mechanism, the wheel 210 is slidably connected to the bottom shell 100 through the bracket 220, and can move upward or downward, so that there is a movable amount between the bottom shell 100, thereby improving the obstacle-crossing ability and shock absorption of the swimming pool sewage vacuum machine, and also ensuring the stability of the swimming pool sewage vacuum machine during operation; a limiting groove 222 is provided on the sliding section 221, and an elastic hook 110 is provided on the bottom shell 100. Through the cooperation of the elastic hook 110 and the limiting groove 222, the bracket 220 can slide up and down while realizing the connection with the bottom shell 100. At the same time, this design also facilitates the installation of the bracket 220.

[0060] The present embodiment further provides a swimming pool vacuum cleaner, including a wheel mechanism. Therefore, the technical advantages and effects achieved by the swimming pool vacuum cleaner also include the technical advantages and effects achieved by the above-mentioned wheel mechanism, which will not be repeated here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
