Description

Technical Field

[0001] The utility model particularly relates to a cat scratching post plug. Background Art

[0002] A cat scratching post (also known as a cat climbing post) is a pet product with a rope or cardboard wrapped around the inner surface. Cats can use the scratching post to sharpen their claws, climb and exercise, and satisfy their instinctive needs. In order to reduce costs and reduce weight, the inner cores of cat scratching posts currently mostly adopt hollow cylinders. For example, the China Patent Office authorized the disclosure of the announcement number CN220088270U on November 28, 2023, and the name is a utility model patent technology for a spliced ​​cat scratching post, which includes a base plate, an inner core assembly, an end cover and a cardboard. The inner core assembly is a hollow structure and is vertically installed on the upper part of the base plate. It includes an upper inner core section and a lower inner core section. The lower inner core section is fixedly connected to the base plate by a fixing member, and the end cover is fixedly connected to the top of the upper inner core section. Multiple groups of cardboards are sequentially sleeved on the outside of the inner core assembly in the vertical direction. The base plate, inner core assembly and end cover of the above-mentioned cat scratching post are reusable, and the cardboard for cat claws can be replaced, avoiding the problem that the currently used cat scratching posts are often an integrated design. When the cat claw post is damaged after long-term use and needs to be replaced, the entire product needs to be replaced, which increases the user's usage cost.

[0003] The end cap of the cat scratching post of the above technology is used as a plug to limit the cardboard. When a rope is wrapped around the cat scratching post, the end cap can also prevent the rope from falling off from the end. The end cap bottom plate of the cat scratching post of the above technology is installed with a threaded column, and the threaded column is threadedly connected to the threaded sleeve provided at the top of the upper section of the inner core. At present, in order to reduce costs, the inner core of the cat scratching post is mostly made of paper hollow cylinder. It is very difficult to process threads on the paper hollow cylinder. The end cap of the above structure cannot be applied to the paper hollow inner core. Utility Model Content

[0004] The purpose of the utility model is to provide a cat scratching post plug, which adopts an insert-type fixed structure, does not need to process threads on the inner core column, has a good sealing effect, is suitable for use with inner cores of various materials, and has a wide range of applications.

[0005] The present invention is realized by the following technical solutions:

[0006] That is, a cat scratching post plug, characterized in that it includes an insertion part and a sealing part, the insertion part includes a hollow cylindrical first shell with one end open, the outer diameter of the closed end of the first shell is larger than the outer diameter of the first shell, and a limiting hole is provided on the closed end of the first shell, the sealing part includes a hollow cylindrical second shell with one end open, a limiting plate corresponding to the position of the limiting hole is provided on the inner side of the closed end of the second shell, and a limiting block with a wedge-shaped cross-section protruding outward is provided on the front end side of the limiting plate, and the inner diameter of the second shell is equal to or larger than the outer diameter of the closed end of the first shell.

[0007] The outer diameter of the first shell of the utility model matches the inner diameter of the inner core of the cat scratching post to be inserted. In order to ensure that the insertion part is firmly connected after being inserted into the inner core and is not easy to fall off, the two are preferably interference fit.

[0008] The outer diameter of the closed end of the first shell of the utility model is equal to or greater than the outer diameter of the cat climbing post after the rope is wound.

[0009] The utility model is made of plastic as a whole. When inserted into the limiting hole, it can be slightly deformed so that the limiting block at the front end of the limiting plate passes through the limiting hole. When the limiting block passes through the limiting hole, the limiting plate returns to its original shape, and the wedge-shaped limiting block can effectively prevent the blocking part from separating from the insertion part.

[0010] Furthermore, a center column concentric with the first shell is provided at the inner center of the first shell of the present invention, and a reinforcing rib is provided between the center column and the first shell.

[0011] By adopting the above structure, the strength of the first shell can be ensured while reducing weight and cost.

[0012] Furthermore, the reinforcing ribs of the present invention are radially and equally distributed around the circumference.

[0013] Furthermore, the center column of the reinforced rib plate of the present invention is a hollow column.

[0014] The open end of the first shell of the reinforcing rib plate of the utility model is provided with a diameter-changing section, and the cross section of the diameter-changing section is in a frustum shape.

[0015] The front end of the first shell is a frustoconical diameter-reducing section with a gradually decreasing outer diameter, which is easier to insert into the middle hole of the inner core.

[0016] Furthermore, the outer side of the first shell of the present invention is provided with outer ribs which divide the circumference equally and are distributed along the axial direction of the first shell. The outer ribs are wedge-shaped and their thickness gradually increases from the front to the back.

[0017] The utility model provides external ribs on the outside of the first shell. When the first shell is inserted into the middle hole of the inner core, the external ribs gradually increase the extrusion and friction on the middle hole of the inner core as the insertion depth increases. When the first shell is fully inserted, the connection between the two is more secure.

[0018] The utility model has the advantages of reasonable structure, flexible and convenient use, and wide application range. The utility model has a good blocking effect on the end of the cat scratching post, does not require processing threads on the inner core, is suitable for inner cores of various materials, and has a wide application range.
