Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please see Figures 1 to 5 This utility model provides a protective sleeve for assembling items. The protective sleeve includes a base 1 and a cover 2. The base 1 has an assembly groove 10, and the cover 2 is placed in the assembly groove 10 with its outer periphery abutting against the assembly groove 10 to form a closed assembly space. This allows the cover 2 to be circumferentially and radially limited relative to the base 1, and restricts the cover 2 from moving axially toward the base 1. The base 1 is provided with a first positioning block 3 that can move laterally. When the first positioning block 3 is in a first position, a snap-fit ​​position is defined between the side of the first positioning block 3 away from the cover 2 and the base 1. The cover 2 is provided with a second positioning block 4 that at least partially overlaps with the axial projection surface of the first positioning block 3. The base 1 is also provided with a push block 5 and a reset member. The push block 5 is exposed externally and is used to control the first positioning block 3 to move away from the first position. The reset member is used to provide a reset force to move the first positioning block 3 toward the first position, so that the second positioning block 4 is positioned at or away from the snap-fit ​​position.

[0027] In this embodiment of the invention, the protective sleeve includes a base 1 and a cover 2. The cover 2 is placed in the mounting groove 10 of the base 1, and the outer periphery of the cover 2 abuts against the mounting groove 10. Thus, the cover 2 and the base 1 form an assembly space that can be used to assemble electronic devices such as cards or mobile phones. Simultaneously, the cover 2 cannot move relative to the base 1 in the circumferential and radial directions, and also cannot move relative to the base 1 along the axial direction on the side of the cover 2 facing the base 1. Furthermore, the second positioning block 4 can be engaged in a locking position, which is defined by the side of the first positioning block 3 opposite to the cover 2 and the base 1. This ensures that the cover 2 cannot move relative to the base 1 along the axial direction on the side of the cover 2 opposite to the base 1. Therefore, through the above structure, a relatively enclosed assembly space between the cover 2 and the base 1 can be achieved, with a stable connection. This eliminates the need for multiple sets of magnets, resulting in a simple structure, low cost, and light weight, thus improving portability. In addition, the first positioning block 3 can be moved laterally by the push block 5 and the reset component, so that the second positioning block 4 is positioned at or away from the snap-fit ​​position. Thus, during use, the entire cover 2 and the base 1 can be detachably connected by pushing the push block 5, which is simple to operate and improves the user experience.

[0028] Furthermore, in some embodiments, the reset member includes a spring arranged laterally, with one end of the spring abutting against the seat 1 and the other end abutting against the first positioning block 3.

[0029] Specifically, the reset component can be a spring. During disassembly, pushing the push block 5 moves the first positioning block 3 away from the first position. At this time, the spring is compressed, and the second positioning block 4 can separate from the snap-fit ​​position. Then, when the push block 5 is released, the reset component moves the first positioning block 3 closer to the first position, and the first positioning block 3 resets. During assembly, similarly, pushing the push block 5 moves the first positioning block 3 away from the first position, compressing the spring, and the second positioning block 4 can be positioned in the snap-fit ​​position. Releasing the push block 5 moves the reset component closer to the first position, and finally the first positioning block 3 moves to the first position, at which point the second positioning block 4 can snap into the snap-fit ​​position. The entire disassembly and assembly process is convenient and quick.

[0030] Furthermore, in some embodiments, the first positioning block 3 is provided with a spring mounting groove, which has a closed end and an open end arranged laterally opposite to each other, with one end of the spring abutting against the closed end and the other end abutting against the seat 1 through the open end.

[0031] Specifically, the free end of the spring abuts against the closed end of the spring mounting slot, and the fixed end of the spring abuts against the base 1. During operation, pushing the push block 5 will apply a force to the closed end of the spring, thereby compressing the spring. When the push block 5 is released, the spring will push the closed end to move under the action of the restoring force.

[0032] In other embodiments, the reset element can be a structural component with a reset function. Exemplarily, it can be other elastic elements, or a set of magnets with opposite magnetic properties. Furthermore, it is understood that when the reset element is a set of magnets with opposite magnetic properties, the weight is also lower than that of multiple sets of magnets in related technologies, since only short-range displacement control is needed.

[0033] Furthermore, in some embodiments, the first positioning block 3 has a first positioning part 31 protruding laterally, and the first positioning part 31 has a first abutting surface 311 that is axially opposed to the cover 2; the second positioning block 4 has a second positioning part 41 protruding laterally, and the second positioning part 41 has a second abutting surface 411 that is opposed to the seat 1, and the first abutting surface 311 abuts against the second abutting surface 411; and the first abutting surface 311 and the seat 1 form a locking position.

[0034] Specifically, the first positioning block 3 and the base 1 can be integrally formed or separately connected; while the second positioning block 4 and the cover 2 can be integrally formed or separately connected. Furthermore, a locking position can be defined between the first abutting surface 311 of the first positioning part 31 and the side of the base 1 facing the cover 2. Therefore, when the second positioning block 4 is in the locking position, and the second abutting surface 411 abuts against the first abutting surface 311, the first abutting surface 311 can restrict the cover 2 from moving away from the base 1; and since the cover 2 is placed on the base 1, there is relative circumferential and radial limitation between the cover 2 and the base 1, and the cover 2 cannot move axially towards the base 1, a stable connection between the cover 2 and the base 1 can be achieved.

[0035] Furthermore, in some embodiments, the assembly groove 10 has four groove walls 101, and the seat body 1 is also provided with a first limiting structure 102 protruding from the groove wall 101 and orthogonal to the groove wall 101, the first limiting structure 102 corresponding to the groove wall 101 one by one; the cover body 2 has a side wall 21 and a second limiting structure 22 orthogonal to the side wall 21, the second limiting structure 22 corresponding to the side wall 21 one by one; the side wall 21 abuts against the groove wall 101, and the side of the first limiting structure 102 facing the cover body 2 abuts against the second limiting structure 22.

[0036] Specifically, the base 1 has a square structure, and the mounting groove 10 has four groove walls 101, which are opposite each other in pairs. Correspondingly, the cover 2 has four side walls 21, so that axial and circumferential limiting can be achieved when the groove walls 101 and the side walls 21 abut. In addition, the base 1 is also provided with a first limiting structure 102 protruding from the groove walls 101 and orthogonal to the groove walls 101. Correspondingly, the cover 2 has a second limiting structure 22 orthogonal to the side walls 21. The side of the first limiting structure 102 facing the cover 2 abuts against the second limiting structure 22. In this way, the first limiting structure 102 can restrict the cover 2 from moving axially in the direction facing the cover 2. Since the first limiting structure 102 is orthogonal to the groove walls 101 and the second limiting structure 22 is orthogonal to the side walls 21, it is beneficial to place the cover 2 in the mounting groove 10 of the base 1.

[0037] In some specific embodiments, the first limiting structure 102 and the corresponding groove wall 101 can be L-shaped grooves, with the opening of the L-shaped groove facing the cover 2 and the assembly groove 10. The second limiting structure 22 and the corresponding side wall 21 can be square, thus allowing the square to be placed within the L-shaped groove. Since the base 1 has L-shaped grooves on all four sides and the cover 2 has square shapes on all four sides, axial and circumferential limiting can be achieved, as well as restricting the cover 2 from moving axially towards the mounting groove 10. Furthermore, since the opening of the L-shaped groove faces the cover 2 and the assembly groove 10, the ease of connection between the cover 2 and the base 1 is further improved.

[0038] In other embodiments, the first limiting structure 102 and the groove wall 101 may not be orthogonal. Correspondingly, the second limiting structure 22 and the side wall 21 may not be orthogonal. In the same way, axial and circumferential limiting can be achieved, as well as limiting the cover 2 to move axially toward the cover 2. This will not be elaborated here.

[0039] In other embodiments, the assembly groove 10 can also realize other structures arranged along the axial direction and along the radial direction. The corresponding cover 2 can be other structures, which can also realize axial and circumferential limiting, as well as restrict the cover 2 from moving along the axial direction toward the cover 2. These will not be elaborated here.

[0040] Furthermore, in some embodiments, the first positioning block 3 is disposed in one of the first limiting structures 102, and the second positioning block 4 protrudes axially from the second limiting structure 22; wherein, the second positioning block 4 includes a body and a second positioning part 41, the first limiting structure 102 is provided with a relief groove, the body is located in the relief groove, and the first abutting surface 311 abuts against the second abutting surface 411.

[0041] Specifically, one of the four first limiting structures 102 can be used to set the first positioning block 3, and correspondingly, one of the four second limiting structures 22 is used to set the second positioning block 4. The first limiting structure 102 with the first positioning block 3 has a clearance groove. When the push block 5 is pushed, causing the first positioning block 3 to move away from the first position, the second positioning part 41 of the second positioning block 4 is in the snap-fit ​​position, the first abutting surface 311 abuts against the second abutting surface 411, and the body is located in the clearance groove, so that the cover 2 and the seat 1 can naturally combine to form a closed assembly space.

[0042] Furthermore, in some embodiments, one of the groove walls 101 is also provided with a groove that connects to the clearance groove, and the side wall 21 has a protruding structure that matches the groove, and the protruding structure is placed in the groove.

[0043] Specifically, a groove is formed on the groove wall 101 corresponding to the first positioning block 3 and the clearance groove 102, thereby connecting the groove and the clearance groove. Correspondingly, a protruding structure protrudes from the side wall 21. Thus, the other side walls 21 of the cover 2 abut against the groove wall 101 of the assembly groove 10, while this side wall 21 of the cover 2 partially abuts against the groove wall 101, and the other part is provided with a protruding structure, which abuts against the groove. In this way, a part of the cover 2 can be exposed to the outside, which is beneficial for opening and assembling the cover 2.

[0044] In addition, the raised structure can be flush with the outermost sidewall 21 of the base, thus making the overall structure flat and increasing its aesthetic appeal.

[0045] Furthermore, in some embodiments, the first limiting structure 102 is also provided with a telescopic member 11 that can move along the axial direction. The telescopic member 11 and the first positioning block 3 are disposed on the same first limiting structure 102, and the second limiting structure 22 abuts against the telescopic member 11.

[0046] Specifically, a spring can be installed inside the telescopic component 11. When the cover 2 and the seat 1 are assembled and connected, the second limiting structure 22 can press the telescopic component 11, thereby compressing the spring and making it more tactile; when disassembling, the telescopic component 11 can provide a restoring force, so that the cover 2 can be better separated from the seat 1, thereby playing an auxiliary role in opening; thus, it is beneficial to open and assemble the cover 2.

[0047] Furthermore, in some embodiments, the base 1 is also provided with a first sliding groove that connects to the assembly groove 10 and extends laterally, and the first positioning block 3 is placed in the first sliding groove; the base 1 is also provided with a second sliding groove that connects the first sliding groove and the outside, and the push block 5 is connected to the first positioning block 3 and placed in the second sliding groove.

[0048] Specifically, the first positioning block 3 can move within the first sliding groove, which restricts its lateral movement. Additionally, the push block 5 is connected to the first positioning block 3, allowing it to move. Furthermore, the second sliding groove can be located on the groove wall 101 of the base 1 or on the axial bottom wall of the base 1. The push block 5 is connected to the first positioning block 3 and the outside via the second sliding groove, which restricts its direction of movement and facilitates user-assisted pushing.

[0049] Furthermore, in some embodiments, the cover 2 is a tempered glass film, the side of the base 1 opposite to the cover 2 is provided with a lens clearance hole, and the side wall 21 of the base 1 is provided with a volume clearance hole and an interface clearance hole.

[0050] Specifically, protective cases or covers are commonly used for portable devices such as mobile phones. Common mobile phone cases are typically open-type enclosures, exposing the screen. While some protective covers combine the casing and screen protector into one unit, these typically rely on magnetic attraction or a combination of magnetic attraction and snap-fit ​​for detachable connection. This also results in increased weight, making them less portable, and presents technical problems such as complex structure and high cost. In this embodiment, however, the protective cover can be used to mount mobile phones and other electronic devices. The cover 2 can function as a tempered glass screen protector, and a protective film can be applied to the tempered glass. Furthermore, the base 1 can be adapted to accommodate mobile phones and other devices by incorporating volume and interface clearance holes, thus serving as a protective cover for mobile phones and other electronic devices.

[0051] In some specific embodiments, the protective case serves as a protective case for electronic devices such as mobile phones. The first positioning block 3 can be located on the top of the base 1, so as not to affect functions such as volume and buttons. The second positioning block 4 and other structures are adapted accordingly. It can be understood that, without affecting functions such as volume and buttons, they can also be located on the bottom and sides of the base 1.

[0052] In other embodiments, the protective cover can be used to collect cards such as rating cards. The protective cover can be a transparent square, and protective films can be attached to the opposite sides of the cover 2 and the base 1.

[0053] It is understood that the protective sleeve of this utility model embodiment can also be used to assemble other items, which will not be described in detail here.

[0054] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0055] The above is a description of the technical solution provided by this utility model. For those skilled in the art, based on the idea of ​​the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
