[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-5 The bracket structure shown includes a bed board 3 and a support leg 4. One side of the bed board 3 is rotatably mounted on the cat hole frame 1 via a connector 5. Specifically, the connector 5 is a conventional plug-in swivel. The connector 5 is fixed to the cat hole frame 1. The side of the bed board 3 is fixed with a collar that plugs into the connector 5 and can rotate vertically along the connector 5. The support leg 4 is vertically fixed to the upper end of the floor 2 and supports the bottom of the bed board 3 on the side away from the connector 5.

[0026] Because the bed board 3 is detachably connected to the cat-ear hole keel 1 by a plug-in method, it is convenient to quickly disassemble and assemble the bed board 3. The rotating connection design of the collar and the plug-in swivel allows the bed board 3 to be flipped up and down for easy and quick storage. When stored, it can free up more usable space and make the layout more convenient and flexible. The bed board 3, together with the support legs 4, can provide a lateral pull on the cat-ear hole keel 1, making the cat-ear hole keel 1 more stable.

[0027] Among them, a positioning sleeve 6 is fixed at the bottom of the side of the bed board 3 away from the connector 5. The positioning sleeve 6 is sleeved on the top of the support leg 4 to enhance the relative fixation between the bed board 3 and the support leg 4.

[0028] Considering that the bed board 3 is too wide to be easily flipped and stored, the bed board 3 includes a first telescopic part 31 and a second telescopic part 32. The first telescopic part 31 and the second telescopic part 32 are located on the same plane and are horizontally slidably connected. Specifically, the second telescopic part 32 is provided with a limit slider 33 horizontally integrated along its telescopic direction. The first telescopic part 31 is provided with a limit groove 3101 that is adapted to slide with the limit slider 33 along its telescopic direction. The first telescopic part 31 is connected to the connector 5, and the second telescopic part 32 is connected to the positioning sleeve 6. The side end of the second telescopic part 32 away from the first telescopic part 31 is provided with a pull groove 3201.

[0029] In use, the second telescopic part 32 can be manually pulled outward through the hand pull groove 3201 to unfold the bed board 3 to the desired position. Figure 2 As shown, the unfolded bed board 3 is wider, allowing people to lie down safely. The unfolded bed board 3 is also hollow, providing better ventilation. When not in use, the second telescopic part 32 can be pushed towards the first telescopic part 31, and the bed board 3 can be flipped down for storage.

[0030] The support leg 4 includes a support sleeve 41, a support rod 42, and a fixing pin 43. The support sleeve 41 is vertically fixed to the upper end of the floor 2. The support rod 42 is vertically slidably sleeved on the inner side of the support sleeve 41, and the top end of the support rod 42 is inserted into the positioning sleeve 6. The fixing pin 43 passes through the top side end of the support sleeve 41, and the bottom side end of the support rod 42 is provided with a slot that is inserted into the fixing pin 43.

[0031] The retractable support leg 4 is designed to be easy to shorten and store when not in use. On the other hand, it can slide the support rod 42 upward and engage with the positioning sleeve 6 after the bed board 3 is flipped to a horizontal position, making the engagement of the two more stable.

[0032] The working principle of this utility model is as follows: In use, the second telescopic part 32 can be manually pulled outward through the hand pull groove 3201, so that the bed board 3 unfolds to the desired position. Figure 2 As shown, after the bed board 3 is flipped to a horizontal position, the upper sliding support rod 42 and the positioning sleeve 6 are engaged. The unfolded bed board 3 is wider, allowing people to lie down safely. The unfolded bed board 3 is also hollow, which improves air permeability. When not in use, the second telescopic part 32 is pushed toward the first telescopic part 31 and the bed board 3 is flipped downwards for storage.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
