[0035] Through the inclined surface design on the inner side of the clamping block 801, the automatic feeding device body 7 can prevent the inclined surface of the clamping block 801 from being squeezed when it is on the inner side of the other end of the sliding mechanism 6, thereby driving the two clamping blocks 801 to move in opposite directions, thereby causing the linkage plate 804 to pull the movable block 803 to move to one side as a whole, and compress the power spring 805. Then, when the elastic force of the power spring 805 is released, the movable block 803 can be pushed to reset the clamping blocks 801 toward each other through the linkage plate 804.

[0036] like Figure 2 As shown, a flip window 3 located outside the pull-out dog house 4 is hinged on the outer side of the pull-out frame 2 .

[0037] The above solution is adopted: by providing the flip window 3 , since the flip window 3 is hinged to the outside of the drawer frame 2 , it can be flipped open smoothly, so that the drawer dog house 4 can be pulled out from the inner wall of the drawer frame 2 .

[0038] like Figures 2 to 4 and Fig. 9 As shown, the sliding mechanism 6 includes a rotating gear rod 601, a driven gear 602, a driving threaded rod 603 and a moving frame 604;

The driving threaded rod 603 is movably sleeved in the middle of the fixed slide rail frame 5. The driven gear 602 is fixedly sleeved on one end surface of the driving threaded rod 603, and the surface of the driven gear 602 is meshed with the inner end surface of the rotating gear rod 601. The movable frame 604 is movably installed on the inner side of the fixed slide rail frame 5, and one end is threadedly sleeved on the surface of the driving threaded rod 603.

[0040] The above scheme is adopted: by providing a rotating gear rod 601, when the operator rotates the rotating gear rod 601, the teeth on the inner end surface of the rotating gear rod 601 can drive the teeth on the surface of the driven gear 602 to drive the driven gear 602 and the driving threaded rod 603 to rotate as a whole, so as to drive the moving frame 604 to move as a whole.

[0041] like Figures 2 to 4 As shown, the inner side of the movable frame 604 is movably connected to the surface of the automatic feeding device body 7 , and the size of the inner side of the movable frame 604 is adapted to the lateral size of the automatic feeding device body 7 .

[0042] The above scheme is adopted: by providing the automatic feeding device body 7, the operator can install the automatic feeding device body 7 on the inner side of the movable frame 604 through the clamping assembly 8, and then the automatic feeding device body 7 is moved as a whole by the movable frame 604, and is smoothly placed on the inner side of the pull-out kennel 4, avoiding being placed at the door of the pull-out kennel 4, which is inconvenient to place the dog. At the same time, it is convenient to place it on the inner side of the pull-out kennel 4 through movement.

[0043] like Figure 7 As shown, a T-shaped plate 9 is fixedly installed on the top of the limiting shaft 802, and a slope block 10 is arranged on the inner side of the fixed slide rail frame 5. The T-shaped plate 9 and the slope block 10 are in the same horizontal plane, and the slope at one end of the T-shaped plate 9 is adapted to the slope inside the slope block 10.

[0044] The above scheme is adopted: by providing the inclined surface block 10, when the movable frame 604 is moved as a whole to the door position of the drawer kennel 4, the inclined surface at one end of the T-shaped plate 9 can be squeezed by the inner inclined surface of the inclined surface block 10, so that the T-shaped plate 9 and the movable block 803 move to the other side as a whole, so that the linkage plate 804 drives the two clamping blocks 801 to move back to back to release the clamping and fixing effect of the automatic feeding device body 7, so that the automatic feeding device body 7 can be taken down and the food inside can be replenished.

[0045] like Figure 8As shown, the other end of the fixed slide rail frame 5 is provided with a fixing assembly 11 located on the other side of the moving frame 604 and above the clamping block 801, and the fixing assembly 11 includes a gas cylinder 1101, a first pneumatic piston rod 1102, a pneumatic groove 1103, a second pneumatic piston rod 1104, a venting groove 1105 and a fixing block 1106;

[0046] The air cylinder 1101 is fixedly installed inside the other end of the fixed slide rail frame 5 and is located on one side of the T-shaped plate 9. The first pneumatic piston rod 1102 is movably installed inside the air cylinder 1101. The pneumatic groove 1103 is opened inside the other end of the fixed slide rail frame 5 and is located on the outside of the air cylinder 1101. The second pneumatic piston rod 1104 is movably installed in the inner cavity of the pneumatic groove 1103. The pneumatic groove 1103 is connected with the air cylinder 1101 through the ventilation groove 1105. The fixed block 1106 is fixedly installed on the outside of the second pneumatic piston rod 1104.

[0047] The above scheme is adopted: by providing a first pneumatic piston rod 1102, when the mobile frame 604 moves as a whole toward the other end of the fixed slide rail frame 5, the other end of the mobile frame 604 will push the first pneumatic piston rod 1102 to retract into the inner cavity of the gas cylinder 1101, so that the inner cavity on one side of the gas cylinder 1101 is pushed through the ventilation groove 1105 into the pneumatic groove 1103, and the gas in the inner cavity of the gas cylinder 1101 will be stretched, and then when the mobile frame 604 releases the support for the first pneumatic piston rod 1102, the gas on the other side of the inner cavity of the gas cylinder 1101 will be restored, thereby driving the first pneumatic piston rod 1102 to reset and extend.

[0048] like Figure 8 As shown, the protruding portion of the outer side of the fixed block 1106 is matched with the inner groove on the other side of the movable frame 604.

[0049] The above scheme is adopted: by providing a fixed block 1106, when the gas in the inner cavity on one side of the gas cylinder 1101 enters the inner cavity of the pneumatic groove 1103 through the ventilation groove 1105, the air pressure will increase and smoothly push the two second pneumatic piston rods 1104 and the fixed block 1106 to move in opposite directions until the protruding part on the outside of the fixed block 1106 is stuck in the inner groove on the other side of the movable frame 604 to clamp and fix the entire movable frame 604.

[0050] like Figure 8 As shown, the inner wall of the other end of the fixed slide rail frame 5 is provided with a fastening assembly 12 located on one side of the fixing assembly 11, and the fastening assembly 12 includes a triangular block 1201, a fastening frame 1202 and a connecting shaft 1203;

[0051] The triangular block 1201 is fixedly installed on one end of the fixed clamping block 1106 , the fastening frame 1202 is movably installed inside the fixed slide rail frame 5 and is located at one side of the bottom of the triangular block 1201 , and the connecting shaft 1203 is fixedly installed inside the fastening frame 1202 , and the top end extends to the inner wall of the triangular block 1201 .

[0052] By adopting the above solution, the connecting shaft 1203 is provided. When the triangular block 1201 as a whole moves toward or away from each other, the connecting shaft 1203 is squeezed and driven to slide on the inner wall, so that the triangular block 1201 as a whole is driven to move.

[0053] like Figure 3 and Figure 8 As shown, an unlocking push frame 13 is fixedly mounted on one end of the connecting shaft 1203 , and the top end of the unlocking push frame 13 passes through the fixed slide rail frame 5 and extends to one side of the rotating gear rod 601 .

[0054] The above solution is adopted: by providing an unlocking push frame 13, when the operator needs to release the fastening component 12 to release the blocking reinforcement of the T-shaped plate 9, and the fixing component 11 fixes the movable frame 604, at this time, the unlocking push frame 13 can be pushed to drive the fastening frame 1202 as a whole backward, and the T-shaped plate 9 and the movable frame 604 can be smoothly released.

[0055] like Figure 1 As shown, a dog cabin also includes a dog cabin body 1, and a drawer frame 2 is fixedly connected to the outer side of the inner cavity of the dog cabin body 1.

[0056] The working principle and use process of the present invention:

[0057] First, when the operator needs to place the entire automatic feeding device body 7 inside the drawer kennel 4, he can first manually rotate the rotating gear rod 601 to drive the driven gear 602 and the driving threaded rod 603 to rotate the movable frame 604 to one side, and then place the entire automatic feeding device body 7 horizontally on the inner side of the movable frame 604. At this time, the surface of the automatic feeding device body 7 will squeeze and push the inclined surface of the clamping block 801, thereby driving the two clamping blocks 801 to move away from each other until the inner end of the clamping block 801 is directly opposite to the groove on the surface of the automatic feeding device body 7, thereby releasing the elastic force of the power spring 805 to push the movable block 803 to move back as a whole, so that the linkage plate 804 deflects and pulls the two clamping blocks 801 to move toward each other, so that the inner end of the clamping block 801 is stuck in the groove on the surface of the automatic feeding device body 7, and the automatic feeding device body 7 is fixed on the inner side of the movable frame 604.

[0058] Then, the operator can rotate the rotating gear rod 601 to drive the driven gear 602 and the driving threaded rod 603 to drive the movable frame 604 and the automatic feeding device body 7 to move toward the other end as a whole, until the other side of the movable frame 604 fits into the inner side of the other end of the fixed slide rail frame 5. At this time, the first pneumatic piston rod 1102 will be pushed to retract into the inner cavity of the gas cylinder 1101, so as to push the gas at one end of the inner cavity of the gas cylinder 1101 into the inner cavity of the pneumatic groove 1103 through the ventilation groove 1105, and then the two second pneumatic piston rods 1104 can be pushed to drive the two fixed blocks 1106 to move in opposite directions. Finally, the protruding part of the outer end of one side of the fixed block 1106 can be stuck in the inner groove on the other side of the movable frame 604, so that the movable frame 604 can be fixed as a whole.

[0059] When the two fixed blocks 1106 move away from each other, the two triangular blocks 1201 will be driven to move away from each other synchronously, so as to squeeze the connecting shaft 1203 to slide on the inner wall of the triangular block 1201, thereby squeezing and driving the fastening frame 1202 to move closer to the fixed block 1106 as a whole, and finally one end of the fastening frame 1202 is inserted into the movable frame 604, so that one side of the T-shaped plate 9 is supported and fixed, thereby reinforcing the T-shaped plate 9, that is, reinforcing the clamping assembly 8 as a whole.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
