Description

Technical Field

[0001] This utility model relates to a cat litter scoop, and more particularly to an adjustable-spacing cat litter scoop. Background Technology

[0002] Litter scoops are commonly used to clean up litter. Traditional scoops have relatively fixed mesh openings, making them suitable for litter with a specific granule size. If you switch to a different brand of litter, it may not work well, as the granule size and mesh size may not match. Some existing products feature a mix of coarse and fine mesh openings, with the front and back sections having different mesh sizes. However, these are not always very convenient to use, and a truly user-friendly product is lacking. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable spacing cat litter scoop.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable-spacing cat litter shovel, comprising a slidably assembled bucket and a filter frame. The bucket has a perforated filter screen portion on its bottom surface. The filter screen portion includes several spaced-apart upper rods, the intervals between which form filter holes. The filter frame is composed of several lower rods. The bucket has a hollow chamber and an interlocking assembly placed within the hollow chamber. The interlocking assembly includes a transverse member, a longitudinal member, an elastic member, and a locking member. The transverse member is fixedly assembled with the filter frame, and there is a gap between the transverse member and the longitudinal member. The device has a sliding inclined surface in contact with the transverse component, which is limited and assembled in the cavity. The longitudinal component and the transverse component are in abutting and linkage engagement, and both of them move reciprocally along a path perpendicular to each other. The elastic component and the transverse component are linked and have an elastic reset tendency. The locking component is fixedly assembled in the cavity. The longitudinal component is elastically engaged and fixed with the locking component through movement. The longitudinal component partially extends out of the bucket to form a button part. The filter frame slides and locks relative to the filter screen part. The lower rod is located below the filter hole on the sliding path of the filter frame and divides the filter hole into several filter units.

[0005] The bottom surface of the bucket is provided with a waist hole that connects to the cavity chamber, and the filter frame and the transverse component are fixed together by a connector passing through the waist hole.

[0006] The elastic element is a spring, the transverse element is provided with an L-shaped left positioning piece, the cavity is provided with a right positioning piece, and the two ends of the elastic element elastically abut against the left positioning piece and the right positioning piece, respectively.

[0007] The cavity is provided with an installation groove, and the installation groove has an open slot on one side wall. The locking element is located in the installation groove.

[0008] The longitudinal member has a protruding locking part and an abutting part, the locking part and the locking member are elastically fastened together, and the sliding inclined surface is provided on the abutting part.

[0009] The locking component has a slot for the locking part to enter, and the slot wall has a locking groove, and the locking part is elastically engaged with the locking groove.

[0010] The lock groove is also provided with a guide plate, which is inclinedly arranged in the lock groove, and the lower end of the guide plate is connected to the opening of the lock groove.

[0011] The end side of the latch is provided with a protruding locking block, and the locking block is rounded at the corner of the top surface.

[0012] The bucket also has a handle, and the handle is provided with a cover, which covers the cavity.

[0013] The cover is provided with several positioning holes, and the handle is provided with a positioning block that fits into the positioning holes.

[0014] The locking mechanism includes a lock seat, a spring, and a clamping block. The lock seat has a slot, and the clamping block has a pair of clamping bars. The clamping block is inserted into the lock seat and moves linearly back and forth by the spring. The clamping bars have locking hooks corresponding to the lock blocks, and the clamping bars perform opposing clamping actions by moving the clamping block.

[0015] The locking hook is located at least at the end of the clamping bar.

[0016] The beneficial effects of this utility model are as follows: The adjustable spacing cat litter shovel provided by this utility model is simple to operate, practical and reliable. It reduces the filter screen pores by pressing to drive the filter frame to move horizontally. The design is also ingenious, converting longitudinal movement into lateral movement.

[0025] Example 1: As Figures 1-7 As shown, an adjustable-spacing cat litter scoop includes a slidably assembled bucket 1 and a filter frame 2. The bucket 1 has a perforated filter screen 3 on its bottom surface. The filter screen 3 includes several spaced-apart upper rods 4, with the intervals between the upper rods 4 forming filter holes 5. In this embodiment, the filter screen 3 is integrally connected to the bucket 1, achieving filtration through a mesh-like layout. It should be noted that this is also equivalent to the upper rods 4 forming an edge. In actual production, the filter holes 5 will be set to the largest possible size to facilitate subsequent adjustment of the hole spacing using the lower rod 6, widening the gap before and after adjustment and ensuring a wider application range.

[0026] The filter frame 2 is composed of several lower rods 6. The bucket 1 has a hollow chamber 7 and an interlocking assembly placed within the hollow chamber 7. The interlocking assembly includes a transverse member 8, a longitudinal member 9, an elastic member 10, and a locking member 11. The transverse member 8 is fixedly assembled with the filter frame 2, and the transverse member 8 and the longitudinal member 9 have a sliding inclined surface 12 in contact. The interlocking assembly drives the filter frame 2 to translate, while simultaneously moving the lower rods 6 and dividing the filter holes 5. The transverse member 8 is directly connected to the filter frame 2. The longitudinal member 9 is used to press and drive the transverse member 8 to move. The elastic member 10 causes the transverse member 8 to reset, and the locking member 11 maintains the filter frame 2 in its working state. In summary, pressing down on the longitudinal member 9 drives the transverse member 8 to translate, and the filter frame 2 and the lower rods 6 move to divide the filter holes 5. The longitudinal member 9 is simultaneously engaged and fixed with the locking member 11, and resets under external force and the drive of the elastic member 10. It should be noted that in this embodiment, the longitudinal member 9 is further pressed into the locking member 11 to reset using a greater compressive elastic restoring force.

[0027] The transverse member 8 is limited and assembled in the cavity 7. The longitudinal member 9 and the transverse member 8 are in abutting linkage cooperation, and both of them move back and forth perpendicular to each other. The elastic member 10 is linked with the transverse member 8 and has an elastic reset tendency. The locking member 11 is fixedly assembled in the cavity 7. The longitudinal member 9 is elastically locked with the locking member 11 by movement. The longitudinal member 9 extends out of the bucket 1 to form a button part 13. The filter frame 2 slides and locks relative to the filter screen part 3. The lower rod 6 is located below the filter hole 5 on the sliding path of the filter frame 2 and divides the filter hole 5 into several filter units.

[0028] The bottom surface of the bucket 1 has a waist-shaped hole connecting to the hollow chamber 7. The filter frame 2 and the transverse member 8 are fixed together by a connector passing through the waist-shaped hole. The waist-shaped hole allows for a small travel distance for screws or bolts. The elastic member 10 is a spring. The transverse member 8 has an L-shaped left positioning piece 15, and the hollow chamber 7 has a right positioning piece 16. The two ends of the elastic member 10 elastically abut against the left positioning piece 15 and the right positioning piece 16, respectively. The left positioning piece 15 and the right positioning piece 16, combined with the structure of the transverse member 8 itself, can meet the positioning and installation requirements, making the structure simple and reliable.

[0029] The cavity 7 is provided with a mounting groove 17, which has an open slot on one side wall. The locking member 11 is disposed in the mounting groove 17. This provides space for the installation of the longitudinal member 9 and the locking member 11, and also facilitates fixing and positioning. The longitudinal member 9 has a protruding locking part 18 and an abutment part 19. The locking part 18 and the locking member 11 are elastically engaged, and the sliding inclined surface 12 is disposed on the abutment part 19. In this embodiment, the sliding inclined surface 12 mainly utilizes the inclined surface of a triangle to convert the longitudinal force into a lateral force. Similarly, when the lateral member 8 is driven by the elastic member 10 and elastically resets, it converts the lateral force back into a longitudinal force.

[0030] The locking element 11 has a slot 20 for the locking part 18 to enter. The slot 20 has a locking groove 21 on its wall, and the locking part 18 elastically engages with the locking groove 21. An injection-molded material with good elastic recovery force can be used to achieve this elastic engagement. Alternatively, an outer silicone or plastic material can be used to enhance the elasticity. Not limited to these methods, the locking part 18 enters the slot 20 and elastically engages with the locking groove 21. A guide plate 22 is also provided within the locking groove 21, inclined within it, with its lower end connected to the opening of the locking groove 21. When resetting is required, continued external force is applied, causing the locking part 18 to penetrate deeper into the slot 20 and disengage from the locking groove 21 via the guide plate 22. Once the elastic recovery force accumulates to a certain level, the locking part 18 is released instantaneously, causing it to quickly disengage from the slot 20. A protruding locking block 23 is provided on the end side of the locking part 18, and the locking block 23 has a rounded corner 24 on its top surface. The rounded design of 24 reduces the obstruction of the lock slot 21 when the lock block 23 leaves the slot 20.

[0031] The bucket 1 also has a handle portion 25, and a cover 26 is provided on the handle portion 25, which covers the cavity chamber 7. The cover 26 is provided with a plurality of positioning holes 27, and the handle portion 25 is provided with positioning blocks 28 that fit into the positioning holes 27. The cover 26 is designed for covering, and the cover 26 is connected by a threaded connection. In this embodiment, multiple positioning holes 27 and positioning blocks 28 are also designed to assist in positioning and fixing.

[0032] Example 2: Different from Example 1, such as Figure 8 As shown, the locking element 11 includes a lock seat 29, a spring, and a clamping block 30. The lock seat 29 has a slot, and the clamping block 30 has paired clamping strips 31. The clamping block 30 is inserted into the lock seat 29 and moves linearly back and forth via the spring. The clamping strips 31 have locking hooks 32 corresponding to the locking blocks, and the clamping strips 31 perform opposing clamping actions as the clamping block 30 moves. The locking hooks 32 are located at least at the ends of the clamping strips 31. This structure has practical advantages, as the added spring increases the elastic restoring impact force, and the locking hooks 32 hook the locking block, allowing for synchronous switching between clamping and releasing depending on the locking or unlocking state. It should be noted that when the clamping block 30 is subjected to force and sinks, it causes the clamping strips 31 to move downwards, and vice versa. This will not be elaborated or limited further here.
