Description

TECHNICAL FIELD

[0001] The utility model relates to pet appliance technical field, especially in a kind of pet feeder push rod anti-collision structure. BACKGROUND

[0002] The grain storehouse bottom of pet feeder is usually provided with a poking mechanism, and two poking rods are usually provided on the poking mechanism. When the poking mechanism is rotated by the motor, the two poking rods also rotate to stir the pet food at the bottom of the grain storehouse, ensuring that the pet food can fall down smoothly from the bottom of the grain storehouse. In the prior art (for example: the patent with the announcement number CN 219679472 U), some grain storehouses are provided with partitions to hold different pet foods in two compartments of the grain storehouse. Since the partitions are provided, the poking rods may interfere with the partitions during rotation. Even if the angle of the motor is set to be close to 180° during each forward rotation and reverse rotation, it is not guaranteed that the poking rods will not hit the partitions at the end of each rotation. Instead, the poking rods may hit the partitions, and the poking rods may break after a long time. To solve the above problems, the angle of the motor during each forward rotation or reverse rotation is set to be too small, which ensures that the poking rods will not hit the partitions. However, the coverage of the poking rods during rotation is small, and the pet food near the partitions cannot be stirred, causing the pet food to be retained. This affects the stirring effect and may even cause the sensor on the food to fail to detect the actual lack of food in the grain storehouse. In view of the above technical problems, the present application proposes a new technical solution that can ensure that the poking mechanism driven by the motor can cover a large range during rotation and can also have a certain buffering effect even if the poking rods collide with the partitions during rotation, to avoid damage to the poking rods after repeated collisions. SUMMARY

[0003] In view of the above shortcomings of the prior art, the purpose of the present utility model is to provide a pet feeder poking rod anti-collision structure to solve the technical problem of the poking mechanism of the pet feeder being easily damaged in the prior art.

[0004] To achieve the above purpose, the present utility model adopts the following technical solution:

[0005] A pet feeder poking rod anti-collision structure includes a rotating rod and a rotating rod cap. The rotating rod cap is provided with a poking rod. The bottom end of the rotating rod cap is provided with a circular insertion hole. The top end of the rotating rod is circular. The top end of the rotating rod is inserted into the insertion hole and is in interference fit. The side wall of the insertion hole is provided with at least one clamping block. The side wall of the rotating rod is provided with a clamping slot. The number of clamping slots is equal to the number of clamping blocks, and the positions of the clamping slots correspond to the positions of the clamping blocks. The width of the clamping block is less than the width of the corresponding clamping slot.

[0006] Further, in the pet feeder poking rod anti-collision structure, two clamping blocks are symmetrically arranged on the inner wall of the insertion hole. Two clamping slots are symmetrically arranged on the top end of the rotating rod.

[0023] The utility model provides a kind of pet feeder push rod anti-collision structure, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following is further detailed to the utility model of the utility model.It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0024] Please refer to Figures 1 to 5 The utility model provides a kind of pet feeder push rod anti-collision structure. The drawing is only used to explain the structure principle, and is not proportional to actual product. The drawing only draws the structure related to the invention point of the present application, and has not specifically drawn some conventional structures. Since prior art (for example: the patent with authorized announcement number CN 219679472 U) has disclosed the structure of entire pet feeder, the structure of entire pet feeder is not specifically drawn in the present application.

[0025] A kind of pet feeder push rod anti-collision structure, including rotating rod 1 and rotating rod cap 2, rotating rod cap is provided with push rod 3, the bottom end of rotating rod cap is provided with round insertion hole 20, the top end of rotating rod is circular, the top end of rotating rod is inserted into insertion hole and is in interference fit;The side wall of insertion hole is provided with at least one clamping block 22, the side wall of rotating rod is provided with clamping groove 102, the number of clamping groove and clamping block is equal and position corresponds;The width of clamping block 22 is less than the width of corresponding clamping groove 102. Since the invention point is in the connecting relationship of rotating rod and rotating rod cap, and the push rod itself is not the invention point of the present application, the number and shape of the push rod are not specifically limited in the present application.

[0026] The top end of the above insertion hole and rotating rod is in interference fit, therefore, when motor (not shown in the drawing) drives rotating rod to rotate, rotating rod drives rotating rod cap to rotate by friction force. When push rod collides with partition, the resistance of partition to rotating rod cap is greater than the friction force between rotating and rotating rod cap, so as to hinder rotating rod cap to continue to rotate;At the same time, since the width of clamping block is less than the width of corresponding clamping groove, rotating rod will continue to rotate a smaller angle (at this time, rotating rod cap does not rotate) until the side wall of clamping block and the side wall of clamping groove abut. That is, as long as motor rotates to the end point (i.e. stops rotating or changes direction) before or when the side wall of clamping block and the side wall of clamping groove abut, it will not cause strong impact on push rod, and at the same time, it can also ensure that push rod can contact with partition during each rotation, so as to ensure the effect of pushing, and avoid pet food near partition to be retained due to not being pushed.

[0027] Preferably, two clamping blocks are symmetrically arranged on the inner wall of insertion hole;The top end of rotating rod is symmetrically provided with two clamping grooves. The arrangement makes the stress condition between rotating rod and rotating rod cap more balanced.

[0028] Preferably, the two card blocks have the same size; the two card slots have the same size.

[0029] Preferably, each card block is made of silica gel, rubber or thermoplastic elastomer. This arrangement makes the card block have a certain elasticity, and during rotation, even if the side wall of the card block and the side wall of the card slot abut, the card block itself can still deform elastically to some extent, ensuring that the card block is not easily damaged.

[0030] As shown in Figure 3 Further, each card slot does not communicate with the end face of the top end of the rotating rod Figure 3 The visual angle only observes one card slot. Since the card block can elastically deform, even if the card slot does not communicate with the end face of the top end of the rotating rod, the rotating rod can be inserted into the insertion hole by external force during assembly (at this time, the card block is clamped into the card slot). Since the card slot does not communicate with the end face of the top end of the rotating rod, when the card block is clamped into the card slot, it also functions as a circumferential limit, and during normal operation (without axial force), the card block cannot be pulled out of the card slot in the axial direction, i.e., the rotating rod cap cannot be separated from the rotating rod in the axial direction.

[0031] Further, the inner wall of the insertion hole is provided with a foolproof block 21. A foolproof groove 101 is formed on the rotating rod, which communicates with the end face of the top end of the rotating rod. During assembly, the foolproof block is aligned with the foolproof groove, and the rotating rod can be inserted into the insertion hole by axial force, thereby facilitating the assembly of the rotating rod and the rotating rod cap.

[0032] Further, the foolproof groove 101 is an arc-shaped groove, and the side wall of the foolproof block is arc-shaped. This arrangement takes into account that the arrangement of the foolproof block and the foolproof groove should not affect the relative rotation between the rotating rod and the rotating rod cap.

[0033] In order to facilitate understanding, Figure 5 A schematic view of the pet feeder rod collision prevention structure and the grain bin 9 is shown. As can be observed in the figure, a partition plate 91 is arranged in the grain bin. When the rotating rod cap rotates, it drives the rod 3 to rotate, and each time it rotates forward or reverses, the rod 3 can move to abut the bottom end of the partition plate, thereby stirring the pet food on both sides of the bottom, avoiding the stagnation of the pet food.

[0034] It can be understood that for those skilled in the art, equivalent substitutions or changes can be made according to the technical scheme and the utility model concept of the present utility model, and all these changes or substitutions should belong to the protection scope of the present utility model.
