[0001] This application relates to the field of pet cleaning technology, specifically to a foldable pet placement device. Background Technology

[0002] Pet grooming is a service that provides cleaning and care for companion animals. Its origins can be traced back to the mid-20th century, emerging with urbanization and the increasing role of pets in families. Modern services have evolved from basic bathing into a systematic process that includes fur cleaning, deworming, ear cleaning, nail trimming, and grooming, aiming to maintain the animal's health and meet the owner's aesthetic needs.

[0003] During the pet cleaning process at pet shops, pet cleaners often place the pets on a cleaning cart for cleaning, but after the cleaning is finished, the cleaning cart cannot be put away, resulting in wasted space. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a foldable pet placement device, which solves the technical problem in the prior art where, during the pet cleaning process at pet shops, pet cleaners often place their pets on a cleaning cart for cleaning, but after cleaning, the cleaning cart cannot be folded up, resulting in wasted space.

[0027] The two ends of the first limiting rod are respectively located adjacent to the two ends of the first support rod group, and are respectively detachably connected to the two ends of the first support rod group;

[0028] When the first limiting rod is assembled onto the first support rod group, the first limiting rod can prevent the first support rod and the second support rod from rotating towards each other, thereby preventing the pet placement device from changing from the unfolded state to the folded state.

[0029] In one possible embodiment, the pet placement device includes four first support rod assemblies and four base rods; the four base rods are distributed around the pet support portion;

[0030] Each of the four base rods is rotatably equipped with a second limiting rod; the ends of the second limiting rods on the four base rods are all connected to the central rotating seat, and form a third support rod group.

[0031] The central rotating seat is used to limit the rotation angle of the second limiting rod, so that the second limiting rod can rotate between the second rotation angle and the third rotation angle.

[0032] In one possible embodiment, the pet placement device includes at least one layer of third support rod assembly;

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

It should be understood that in the specification, claims, and accompanying drawings of the embodiments of this application, the terms "upper," "lower," "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] like Figures 1 to 7 As shown, this application provides a foldable pet placement device, which includes a plurality of first support rod groups 1 and a pet support part 2. The plurality of first support rod groups 1 can be used to support the pet placement device, and the user can place the pet in the pet support part 2.

[0050] In one possible embodiment, a plurality of first support rod assemblies 1 are used to support the pet support part 2, each first support rod assembly 1 including a first support rod 11, a second support rod 12, and a rotation locking assembly 13. When the pet placement device is in the unfolded state, the first support rod 11 and the second support rod 12 can be arranged laterally.

[0051] Optionally, the first support rod 11 and the second support rod 12 can be rotatably connected by a rotary locking assembly 13. The rotary locking assembly 13 can lock the angle between the first support rod 11 and the second support rod 12. When the pet placement device is in the unfolded state, the rotary locking assembly 13 locks the relative angle between the first support rod 11 and the second support rod 12.

[0052] Optionally, the pet placement device includes a folded state and an unfolded state. When the first support rod 11 and the second support rod 12 are locked at a first rotation angle by the rotation locking component 13, the pet placement device is in the unfolded state. At this time, the first support rod 11 and the second support rod 12 can be arranged horizontally, and the first support rod 11 can be coaxial with the second support rod 12. When the rotation locking component 13 releases the angle lock between the first support rod 11 and the second support rod 12, the pet placement device can switch between the unfolded state and the folded state, thereby enabling the pet placement device to be stored.

[0053] Among them, such as Figure 6 As shown, when the pet placement device is in the folded state, the first support rod 11 can rotate to overlap or nearly overlap with the second support rod 12. At this time, both the first support rod 11 and the second support rod 12 rotate from a horizontal (including nearly horizontal) setting to a vertical (including nearly vertical) setting. At this time, each first support rod group 1 also changes from an unfolded state to a folded state, so the first support rod group 1 can be stored, that is, the pet placement device can be stored.

[0054] Optionally, the pet support unit 2 may include a pet support groove 21 and / or a pet support plate 22. A plurality of first support rods 1 can be used to support the pet support groove 21 or the pet support plate 22. The pet support plate 22 may include a plurality of detachable folding panels, which can be folded and disassembled for storage. The pet support plate 22 may cover the pet support groove 21, and its ends may be detachably connected to the support rods within the pet placement device. The pet support groove 21 may also be detachably mounted on the support rods, and it too is a foldable structure.

[0055] Optionally, a brush part 23 can be provided on the pet support part 2. The brush part 23 can be provided on the pet support slot 21 or the pet support plate 22. The operator can use the brush part 23 to clean the pet's hair, thereby achieving the cleaning of the pet's hair.

[0056] In the embodiments of this application, during the use of the pet placement device, the rotation locking component 13 can release the angle lock between the first support rod 11 and the second support rod 12, allowing the pet placement device to switch between an unfolded state and a folded state. When a user needs to place a pet in the pet placement device, the rotation locking component 13 can lock the relative angle between the first support rod 11 and the second support rod 12 to a first rotation angle, thereby ensuring that the pet placement device remains stably in the unfolded state.

[0057] The user can manually press or push the rotation locking component 13 to separate the rotation locking component 13 from the first support rod 11 and the second support rod 12, thereby canceling the angle lock between the first support rod 11 and the second support rod 12.

[0058] In one possible embodiment, such as Figure 3 and Figure 4 As shown, the rotary locking assembly 13 includes a rotary locking base 131, a first guide 132 and a second guide 133. The first guide 132 and the second guide 133 are both disposed on the rotary locking base 131 and can be movably connected to the rotary locking base 131.

[0059] Optionally, the first guide member 132 may correspond to the first support rod 11. The first guide member 132 can contact or separate from the first support rod 11. When the first guide member 132 is connected to the first support rod 11, the first guide member 132 guides the installation of the first support rod 11, thereby locking the first support rod 11 to the first rotation angle.

[0060] Optionally, the second guide 133 can correspond to the second support rod 12. The second guide 133 can contact or separate from the second support rod 12. When the second guide 133 is connected to the second support rod 12, the second guide 133 guides the installation of the second support rod 12, thereby locking the second support rod 12 to the first rotation angle.

[0061] Therefore, when the first guide member 132 guides the installation of the first support rod 11 and the second guide member 133 guides the installation of the second support rod 12, both the first support rod 11 and the second support rod 12 are locked to the first rotation angle, thereby achieving angle locking between the first support rod 11 and the second support rod 12.

[0062] In one possible embodiment, the rotation locking assembly 13 further includes a third guide 134, which can be used to guide the installation of the first guide 132 and the second guide 133, thereby ensuring that the first guide 132 and the second guide 133 always maintain a specific installation angle on the third guide 134.

[0063] Optionally, the third guide member 134 may include a first guide groove 135 and a second guide groove 136. The first guide member 132 may be slidably disposed in the first guide groove 135, and the second guide member 133 may be slidably disposed in the second guide groove 136. The first guide groove 135 provides sliding support for the first guide member 132, and the second guide groove 136 provides sliding support for the second guide member 133.

[0064] Therefore, the first guide member 132 and the second guide member 133 can be slidably supported and guided by the third guide member 134, thereby limiting the first guide member 132 and the second guide member 133 to maintain a specific installation angle.

[0065] In one possible embodiment, the rotating locking base 131 is provided with a first limiting part 137 and a second limiting part 138. The first limiting part 137 and the second limiting part 138 are used to limit the positions of the first guide member 132 and the second guide member 133, thereby driving the first guide member 132 and the second guide member 133 to slide in the first guide groove 135 and the second guide groove 136.

[0066] Optionally, the first limiting part 137 includes a first limiting surface, and the first guide member 132 can be in contact with the first limiting surface. The second limiting part 138 includes a second limiting surface, and the second guide member 133 can be in contact with the second limiting surface. The first limiting surface and the second limiting surface are respectively used to push the first guide member 132 and the second guide member 133 to slide in the first guide groove 135 and the second guide groove 136.

[0067] Optionally, when the pet placement device changes from a folded state to an unfolded state, the first limiting surface pushes the first limiting part 137 and the second limiting surface pushes the second limiting part 138, the first guide 132 separates from the first support rod 11 and the second guide 133 separates from the second support rod 12, thereby canceling the angle locking between the first support rod 11 and the second support rod 12 by the rotation locking assembly 13.

[0068] Optionally, at the connection between the first guide member 132 and the first support rod 11, the shape of the first guide member 132 corresponds to that of the first support rod 11. The first guide member 132 can be sleeved outside the first support rod 11, or the first support rod 11 can be sleeved outside the first guide member 132. At the connection between the second guide member 133 and the second support rod 12, the shape of the second guide member 133 corresponds to that of the second support rod 12. The second guide member 133 can be sleeved outside the second support rod 12, or the second support rod 12 can be sleeved outside the second guide member 133.

[0069] In one possible embodiment, a first compression spring 139 is provided between the first guide member 132 and the bottom of the first guide groove 135. When the first guide member 132 is connected to the first support rod 11, the first compression spring 139 is used to push the first guide member 132 so that the first guide member 132 is stably connected to the first guide groove 135.

[0070] Similarly, a second compression spring 140 is provided between the bottom of the second guide member 133 and the second guide groove 136. When the first guide member 132 is connected to the first support rod 11, the first compression spring 139 is used to push the first guide member 132 so that the first guide member 132 is stably connected to the first guide groove 135.

[0071] In one possible embodiment, a guide hole 141 is provided in the rotary locking base 131, and a third guide member 134 is slidably disposed in the guide hole 141. The third guide member 134 can reciprocate within the guide hole 141 and can reciprocate vertically within the guide hole 141. A third compression spring 142 is provided between the third guide member 134 and the bottom of the groove of the guide hole 141, and the third compression spring 142 is used to support the third guide member 134.

[0072] Optionally, after the third guide 134 has finished sliding, the third compression spring 142 is used to push the third guide 134 to return the third guide 134 to its initial position. The initial position of the third guide 134 can be the highest position in which the third guide 134 slides within the guide hole 141.

[0073] In one possible embodiment, the pet placement device includes four first support rod groups 1, which are used to form a rectangular support rod group capable of supporting the pet support part 2.

[0074] Optionally, the first and last ends of the four first support rod groups 1 are sequentially aligned, and the interval angle between any two adjacent first support rod groups 1 can be 90°. In embodiments other than those shown in the example, the four first support rod groups 1 can be connected end to end.

[0075] In one possible embodiment, the pet placement device further includes a second support rod group 3 corresponding to a plurality of first support rod groups 1. The second support rod group 3 includes a third support rod 31 and a fourth support rod 32. Each second support rod group 3 may be disposed above or below the first support rod group 1.

[0076] Optionally, the third support rod 31 corresponds to the position of the first support rod 11, and the third support rod 31 can rotate synchronously with the first support rod 11; the fourth support rod 32 corresponds to the position of the second support rod 12, and the fourth support rod 32 can rotate synchronously with the second support rod 12. Both the third support rod 31 and the fourth support rod 32 can be rotatably connected to the rotation locking assembly 13.

[0077] Optionally, when the pet placement device is in the unfolded state, the third support rod 31 and the fourth support rod 32 are used to support the pet support part 2.

[0078] In one possible embodiment, the pet placement device further includes at least one limiting rod, with both ends of the limiting rod respectively disposed adjacent to both ends of the first support rod group 1, and the limiting rod can be detachably disposed on both ends of the first support rod group 1.

[0079] Optionally, the pet placement device includes four first support rod groups 1 and two limiting rods, and the limiting rods can be set on any two of the four first support rod groups 1.

[0080] Optionally, the pet placement device includes four first support rod groups 1 and four limiting rods, with one limiting rod on each first support rod group 1.

[0081] When the limiting rod is assembled onto the first support rod group 1, the limiting rod is used to limit the distance between the two ends of the first support rod 11 and the second support rod 12. The limiting rod can prevent the first support rod 11 and the second support rod 12 from rotating towards each other, thereby preventing the pet placement device from changing from the unfolded state to the folded state.

[0082] In one possible embodiment, such as Figures 5 to 7As shown, the pet placement device may include four first support rod groups 1 and four base rods 5. The four base rods 5 may be distributed around the pet support part 2, and each base rod 5 may be vertically installed at the connection point of every two adjacent first support rod groups 1.

[0083] Optionally, each base rod 5 can be a telescopic rod structure, and the bottom of each base rod 5 can be provided with a pulley structure. The pet placement device in this application can be a pet washing cart.

[0084] Optionally, each of the four base rods 5 is rotatably equipped with a second limiting rod 51. The first end of the second limiting rod 51 on each of the four base rods 5 is connected to the base rod 5, and the end of the second limiting rod 51 on each of the four base rods 5 is connected to the central rotating seat 52.

[0085] Optionally, the central rotating seat 52 is used to limit the rotation angle of the second limiting rod 51, so that the second limiting rod 51 can rotate between the second rotation angle and the third rotation angle. When each of the second limiting rods 51 rotates to the second rotation angle, the pet placement device is in the unfolded state; when each of the second limiting rods 51 rotates to the third rotation angle, the pet placement device is in the folded state. Thus, the four base rods 5 can be folded or unfolded.

[0086] Optionally, each base rod 5 is provided with two second limiting rods 51, one above the other. The second limiting rod 51 above each of the four base rods 5 and the central rotating seat 52 together form a third placement rod group. The second limiting rod 51 below each of the four base rods 5 and the central rotating seat 52 together form a third placement rod group. Each third placement rod group is used to place items.

[0087] Optionally, the central rotating seat 52 of the upper and lower third placement rod groups is connected by a transmission rope 53. When any one of the upper and lower third placement rod groups is folded, the other third placement rod group is also folded, thereby improving the folding efficiency and stability of the pet placement device.

[0088] In one possible embodiment, the pet placement device includes at least one layer of third support rods, each layer of third placement rods including four second limiting rods 51 and a central rotating seat 52.

[0089] Optionally, when the number of the third support rod groups is greater than or equal to two layers, the central rotating seat 52 of each layer of the third support rod group is connected by a transmission rope 53. A transmission rope 53 is sandwiched between every two adjacent third support rod groups. The transmission rope 53 can be a rigid rope or an elastic rope. The transmission rope 53 can be replaced with a transmission belt as needed. The transmission rope 53 is used to make at least one layer of the third support rod group move synchronously.

[0090] In one possible embodiment, such as Figure 1 and Figure 6 As shown, when the pet placement device is placed on the ground, the first support rod 11 and the second support rod 12 are located above the third support rod group. When the pet placement device transitions from the unfolded state to the folded state, the first support rod 11 and the second support rod 12 fold downwards, which can drive the rotating locking assembly 13 to move downwards. The second limiting rod 51 folds upwards, which can drive the central rotating seat 52 to move upwards. Furthermore, the first support rod 11, the second support rod 12, and the second limiting rod 51 together drive the central rotating seat 52 and the rotating locking assembly 13 to move towards each other, thereby achieving vertical storage between the first support rod 11 and the second support rod 12 and saving vertical space after the pet placement device is folded.
