Description

Technical Field

[0001] The utility model relates to the technical field of tablet computer accessories, in particular to a tablet computer protective case that can be folded into a bracket. Background Art

[0002] A tablet computer, also called a portable computer, is a small and portable personal computer with a touch screen as the basic input device. It has a touch screen (also known as digitizer technology) that allows users to operate with a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, on-screen soft keyboard, voice recognition, or a real keyboard (if equipped with the model).

[0003] A tablet computer protective case is an accessory used to protect a tablet computer. When the tablet computer accidentally falls or is collided, it provides a certain buffer and protection, reduces damage to the device, and prevents the shell of the tablet computer from being scratched or worn. Common materials for the protective case include silicone, plastic, leather, cloth, etc. With the development of technology, existing tablet computer protective cases can be folded into brackets to conveniently support the tablet computer at an appropriate angle for viewing or operation in different scenarios.

[0004] In daily work, it is found that although existing tablet computer protective cases can be folded into brackets, when folding and supporting, they are easily affected by vibration, resulting in unstable phenomena such as changes in the bracket angle. As a result, users need to frequently adjust the angle, causing wear on the folding part of the protective case, affecting the service life and experience, and further leading to the problem of poor stability when using existing tablet computer protective cases that can be folded into brackets. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantage of poor stability in use in the prior art, and to propose a tablet computer protective case that can be folded into a bracket.

[0006] To achieve the above object, the utility model adopts the following technical solution: A tablet computer protective case that can be folded into a bracket, including a protective case body and a stabilizing device. A folding cover plate is arranged on the surface of the protective case body. The stabilizing device is arranged on the surface of the protective case body. The stabilizing device includes limiting blocks. The number of the limiting blocks is two. The two limiting blocks are fixedly connected to one side surface of the protective case body. Two hollow sleeves are fixedly connected to the surface of the folding cover plate. An insertion block is slidably connected to the inner wall of the hollow sleeve. A plurality of groups of insertion slots are formed on the surface of the limiting block. The insertion block is inserted into the inner wall of the insertion slot. A positioning member is slidably connected to the inner wall of the insertion block. A plurality of groups of limiting holes are formed on the surface of the limiting block. The limiting holes are communicated with the inner wall of the insertion slot. The positioning member is inserted into the inner wall of the limiting hole. An adjusting rod is slidably connected to the inner walls of the two insertion blocks. The adjusting rod is fixedly connected to the surfaces of the two positioning members. Through the above components, when the folding cover plate is folded, the protective case body can lean on the folding cover plate to form a bracket. Subsequently, the insertion block is driven by the adjusting rod to be inserted into the insertion slot on the surface of the limiting block, and then the positioning member is driven by the adjusting rod to be inserted into the limiting hole, completing the angle positioning, reducing the problem that the angle changes due to folding during use, and thus the problem of frequent adjustment affecting the use.

[0007] Preferably, the positioning member includes a sliding block. The sliding block is slidably connected to the inner wall of the insertion block. A positioning column is fixedly connected to one side surface of the sliding block. The positioning column is inserted into the inner wall of the limiting hole on the surface of the limiting block. Through the above components, when the positioning member moves, the sliding block and the positioning column can be driven to move by the adjusting rod. The positioning column can be inserted into the limiting hole to complete the limiting.

[0008] Preferably, a spring is fixedly connected to one side of the sliding block corresponding to the inner wall of the insertion block. The spring is sleeved on the adjusting rod. Through the above components, the spring can apply pressure to the sliding block and the positioning column, enabling the positioning column to be stably inserted into the limiting hole on the surface of the limiting block, improving the stability.

[0009] Preferably, a push plate is fixedly connected to one end of the adjusting rod. Through the above components, the push plate can drive the adjusting rod and the positioning member to move, improving the ease of use.

[0010] Preferably, a supporting device is arranged on the surface of the folding cover plate. The supporting device includes concave blocks. The number of the concave blocks is two. The two concave blocks are fixedly connected to the folding cover plate. A rotating shaft is rotatably connected to the inner wall of the concave block. A threaded sleeve is fixedly connected to the surface of the rotating shaft. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. A supporting pad is fixedly connected to one end of the threaded rod. Through the above components, when the folding cover plate is folded and supported, the threaded sleeve and the threaded rod can be rotated. The threaded rod is rotated in the threaded sleeve, and the threaded rod drives the supporting pad to press on the folding cover plate, which can play a supporting role.

[0011] Preferably, the size of the support pad is larger than the size of the inner wall of the concave block. With the above components, when the threaded rod drives the support pad to rotate and reset, the large-diameter support pad can be inserted into the inner wall of the small-sized concave block, thereby improving the stability effect after reset.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, by providing a stabilizing device, the stability effect of the folded tablet computer protective case can be improved, and it can be fixed at a specific angle, reducing the wear of the folding structure of the protective case caused by frequent angle adjustment after the angle changes, extending the service life of the protective case, and ensuring that the tablet computer will not affect the viewing or operation experience due to accidental angle changes during use.

A positioning member 37 is slidably connected to the inner wall of the insertion block 36. A plurality of groups of limit holes 33 are provided on the surface of the limit block 31. The limit holes 33 are communicated with the inner wall of the insertion slot 32. The positioning member 37 is inserted into the inner wall of the limit hole 33. A connecting rod 34 is slidably connected to the inner walls of the two insertion blocks 36. The connecting rod 34 is fixedly connected to the surfaces of the two positioning members 37.

[0025] In this implementation: When the folding cover plate 2 is folded, the protective case body 1 can lean on the folding cover plate 2 to form a bracket. Subsequently, the connecting rod 34 drives the insertion block 36 to be inserted into the insertion slot 32 on the surface of the limit block 31, and then the connecting rod 34 drives the positioning member 37 to be inserted into the limit hole 33 to complete the angle positioning, reducing the problem that the angle changes due to folding during use, thus requiring frequent adjustment and affecting the use.

[0026] Specifically, the positioning member 37 includes a slider 371. The slider 371 is slidably connected to the inner wall of the insertion block 36. A positioning column 372 is fixedly connected to one side surface of the slider 371. The positioning column 372 is inserted into the inner wall of the limit hole 33 on the surface of the limit block 31.

[0027] In this implementation: When the positioning member 37 moves, the connecting rod 34 can drive the slider 371 and the positioning column 372 to move, and the positioning column 372 can be inserted into the limit hole 33 to complete the limiting.

[0028] Specifically, a spring 39 is fixedly connected to the side of the slider 371 corresponding to the inner wall of the insertion block 36. The spring 39 is sleeved on the connecting rod 34. The spring 39 can apply pressure to the slider 371 and the positioning column 372, enabling the positioning column 372 to be stably inserted into the limit hole 33 on the surface of the limit block 31, improving the stability.

[0029] Specifically, one end of the connecting rod 34 is fixedly connected to a push plate 38. The push plate 38 can drive the connecting rod 34 and the positioning member 37 to move, improving the usability.

[0030] Specifically, a support device 4 is provided on the surface of the folding cover plate 2. The support device 4 includes concave blocks 41. The number of the concave blocks 41 is two.

A support pad 45 is fixedly connected to one end of the threaded rod 44.

[0031] In this embodiment: When the folding cover plate 2 is folded and supported, the threaded sleeve 43 and the threaded rod 44 can be rotated. By rotating the threaded rod 44 in the threaded sleeve 43, the threaded rod 44 drives the support pad 45 to press on the folding cover plate 2, which can play a supporting role.

[0032] Specifically, the size of the support pad 45 is larger than the size of the inner wall of the concave block 41.

[0033] In this embodiment: When the threaded rod 44 drives the support pad 45 to rotate and reset, the large-diameter support pad 45 can be inserted into the inner wall of the small-sized concave block 41, thereby improving the stability effect after reset.

[0034] Working principle: When in use, push the push plate 38 and the connecting rod 34. The connecting rod 34 drives the two sliders 371 and the positioning column 372. The spring 39 is stressed. Then rotate the folding cover plate 2 and fold the folding cover plate 2. After folding, lean the protective sleeve body 1 against the folding cover plate 2. Then drive the connecting rod 34 and the insertion block 36 to move through the push plate 38, so that the insertion block 36 is inserted into the slot 32 on the surface of the limiting block 31. Then release the push plate 38. The spring 39 releases its elastic force and drives the sliders 371 and the positioning column 372 to reset, so that the positioning column 372 is inserted into the limiting hole 33 on the surface of the limiting block 31, and the support angle can be fixed to improve the stability effect. At the same time, during the support process, the rotating shaft 42 and the threaded sleeve 43 can be rotated in the concave block 41.
