When testing or repairing BDU, the upper cover and the lower shell are usually disassembled and separated. However, at present, the disassembly of the upper cover and the lower shell mostly damages the connection between the two, causing the upper cover to be scrapped and unable to be used again, which greatly increases the cost of repair and testing.

[0003] Therefore, there is an urgent need to provide a detachable shell to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable shell to optimize the shell structure to a certain extent and solve the problem that when the upper cover and the lower cover of the BDU are disassembled, the connection needs to be damaged, resulting in the structure being unable to be reused.

[0005] The utility model provides a detachable shell, including an upper cover, a bottom shell and a positioning assembly; the upper cover is formed with a bearing groove and a slot, the slot is connected with the bearing groove, and the positioning assembly is arranged in the bearing groove; the positioning assembly is formed with a pushing portion with one end protruding from the side wall of the upper cover, and pushing the pushing portion can drive the positioning assembly to move from a first position to a second position in the bearing groove, and a first matching portion is formed on the bottom shell at a position corresponding to the slot, the first matching portion can be inserted into the bearing groove through the slot, and when the positioning assembly is in the first position, the first matching portion is connected to the positioning assembly, and when the positioning assembly is in the second position, the first matching portion is separated from the positioning assembly.

[0006] Wherein, the positioning assembly includes a positioning component, and the positioning component includes a main body and a second matching portion; the main body is formed with a snap-fit ​​groove, and the second matching portion is formed in the snap-fit ​​groove; the pushing portion is formed on the outer wall surface of the main body, and the snap-fit ​​groove corresponds to the slot, so that the first matching portion can be inserted into the snap-fit ​​groove and match with the second matching portion.

[0007] Specifically, the first matching portion is a clamping groove, the second matching portion is a clamping protrusion, and the clamping groove is clamped with the clamping protrusion.

[0008] Further, the first matching portion includes a protruding section, and the locking groove is formed on the protruding section.

[0009] Furthermore, the positioning assembly also includes an elastic member, which is arranged in the bearing groove, and one end of the elastic member abuts against the inner wall of the bearing groove, and the other end abuts against a side wall of the positioning member away from the pushing portion.

[0010] In actual application, a first inclined surface is formed at one end of the raised section away from the bottom shell, and a second inclined surface is formed at the second matching portion. The first inclined surface abuts against the second inclined surface so that the positioning assembly can move from the first position to the second position and compress the elastic member.

[0011] Among them, the detachable shell provided by the utility model also includes a baffle, an opening is formed on one side of the supporting groove, the positioning component enters the supporting groove through the opening, the baffle is blocked at the opening, and a through hole is formed on the baffle corresponding to the position of the pushing part, one end of the pushing part passes through the through hole and protrudes from the side of the baffle away from the upper cover.

[0012] Specifically, the baffle is connected to the upper cover by thermal melting.

[0013] Furthermore, there are multiple positioning components, the bearing grooves are arranged in a one-to-one correspondence with the positioning components, and the bearing grooves are distributed circumferentially along the edge of the upper cover toward the bottom shell, and the first matching parts are arranged in a one-to-one correspondence with the positioning components.

[0014] Furthermore, the displacement distance of the positioning assembly from the first position to the second position is the same as the dimension of the pushing portion protruding from the side wall of the upper cover.

[0015] Compared with the prior art, the detachable housing provided by the utility model has the following advantages:

[0016] The detachable shell provided by the utility model comprises an upper cover, a bottom shell and a positioning assembly; the upper cover is formed with a bearing groove and a slot, the slot is connected with the bearing groove, and the positioning assembly is arranged in the bearing groove; the positioning assembly is formed with a pushing portion with one end protruding from the side wall of the upper cover, and the pushing portion can drive the positioning assembly to move from a first position to a second position in the bearing groove, and a first matching portion is formed at a position corresponding to the slot on the bottom shell, the first matching portion can be inserted into the bearing groove through the slot, and when the positioning assembly is located at the first position, the first matching portion is connected to the positioning assembly, and when the positioning assembly is located at the second position, the first matching portion is separated from the positioning assembly.

[0017] From this analysis, it can be seen that the bearing groove formed in the upper cover can provide installation space for the positioning assembly, and through the further formed slot connected to the bearing groove, and the first matching part formed at the position of the bottom shell corresponding to the slot, the bottom shell can be inserted into the bearing groove through the slot through the first matching part and connected to the positioning assembly, thereby realizing the connection between the top cover and the bottom shell.

[0018] Since the positioning assembly in the present application is formed with a pushing portion protruding from the side wall of the upper cover, and the positioning assembly can reciprocate between the first position and the second position in the bearing groove through the pushing portion, when it is necessary to realize the connection between the first matching portion and the positioning assembly, the positioning assembly is first moved to the second position, and then the first matching portion is inserted into the bearing cavity through the slot. Finally, the positioning assembly is moved to the first position through the pushing portion to realize the connection between the first matching portion and the positioning assembly.

[0019] Correspondingly, when the upper cover and the bottom shell need to be separated, the positioning assembly is moved to the second position by the pushing portion, and the first matching portion is pulled out, thereby achieving separation between the upper cover and the bottom shell.

[0020] It can be understood that since the first mating part and the positioning assembly in the present application can be connected or separated, a detachable connection between the upper cover and the bottom shell can be achieved, thereby solving the problem that when the BDU upper cover and lower cover are disassembled, the connection needs to be damaged, resulting in the structure being unusable.

[0036] like Figure 1-Figure 4 As shown, the utility model provides a detachable shell, including an upper cover 1, a bottom shell 2 and a positioning assembly; the upper cover 1 is formed with a bearing groove 102 and a slot 101, the slot 101 is connected with the bearing groove 102, and the positioning assembly is arranged in the bearing groove 102; the positioning assembly is formed with a pushing portion 303 with one end protruding from the side wall of the upper cover 1, and the pushing portion 303 can drive the positioning assembly to move from a first position to a second position in the bearing groove 102, and a first matching portion is formed at a position corresponding to the slot 101 on the bottom shell 2, the first matching portion can be inserted into the bearing groove 102 by the slot 101, and when the positioning assembly is in the first position, the first matching portion is connected to the positioning assembly, and when the positioning assembly is in the second position, the first matching portion is separated from the positioning assembly.

[0037] Compared with the prior art, the detachable housing provided by the utility model has the following advantages:

[0038] The detachable shell provided by the utility model can provide an installation space for the positioning component through the bearing groove 102 formed in the upper cover 1, and through the further formed slot 101 connected to the bearing groove 102, and the first matching part formed at the position of the bottom shell 2 corresponding to the slot 101, so that the bottom shell 2 can be inserted into the bearing groove 102 from the slot 101 through the first matching part and connected to the positioning component, thereby realizing the connection between the top cover 1.

[0039] Since the positioning assembly in the present application is formed with a pushing portion 303 protruding from the side wall of the upper cover 1, and the pushing portion 303 can enable the positioning assembly to reciprocate between the first position and the second position in the bearing groove 102, when it is necessary to connect the first matching portion with the positioning assembly, the positioning assembly is first moved to the second position, and then the first matching portion is inserted into the bearing cavity from the slot 101. Finally, the positioning assembly is moved to the first position through the pushing portion 303 to achieve the connection between the first matching portion and the positioning assembly.

[0040] Correspondingly, when the upper cover 1 and the bottom shell 2 need to be separated, the positioning assembly is moved to the second position by the pushing portion 303 and the first matching portion is pulled out, thereby achieving separation between the upper cover 1 and the bottom shell 2 .

[0041] It can be understood that since the first mating part and the positioning assembly in the present application can be connected or separated, a detachable connection between the upper cover 1 and the bottom shell 2 can be achieved, thereby solving the problem that when the BDU upper cover 1 and the lower cover are disassembled, the connection needs to be damaged, resulting in the structure being unusable.

[0042] It should be noted that the volume of the positioning assembly in the present application is smaller than the volume of the bearing slot 102, so that the positioning assembly can move in the bearing slot 102. The positioning assembly in the present application can use a magnet, and accordingly, the first matching part is a ferromagnetic part or a magnet. When the first matching part is inserted into the bearing slot 102, the magnet of the positioning assembly is moved closer to the first matching part through the pushing part 303, so that the adsorption connection between the positioning assembly and the first matching part can be achieved, and the connection between the upper cover 1 and the bottom shell 2 is completed. When disassembling, the upper cover 1 and the bottom shell 2 can be disassembled by only pulling the pushing part 303 to separate the positioning assembly from the first matching part.

[0043] The positioning component in the present application can also be in the form of a plug-in column. Accordingly, a socket is formed on the first matching part. When the first matching part is inserted into the bearing groove 102, the positioning component is moved by the pushing part 303 so that the plug-in column of the positioning component is inserted into the socket, thereby realizing the connection between the upper cover 1 and the bottom shell 2.

[0044] Alternatively, if Figure 1 Combination Figure 2 and Figure 4 As shown, the positioning assembly in the present application includes a positioning member 3, and the positioning member 3 includes a main body and a second matching portion 302; the main body is formed with a snap-fit ​​groove 301, and the second matching portion 302 is formed in the snap-fit ​​groove 301; the pushing portion 303 is formed on the outer wall surface of the main body, and the snap-fit ​​groove 301 corresponds to the slot 101, so that the first matching portion can be inserted into the snap-fit ​​groove 301 and match with the second matching portion 302.

[0045] By forming the snap-fit ​​groove 301, it can be ensured that after the first matching part is inserted into the slot 101, it can enter the snap-fit ​​groove 301 and match with the second matching part 302, thereby playing a guiding and positioning role, and the main body can provide sufficient space for the formation of the pushing part 303, thereby ensuring the strength of the overall structure to a certain extent.

[0046] Preferably, if Figure 1 Combination Figure 2 and Figure 4 As shown, the first matching portion in the present application is a card slot 202, and the second matching portion 302 is a card-engaging protrusion, and the card slot 202 is card-engaged with the card-engaging protrusion.

[0047] When the first matching portion is the card slot 202 and the second matching portion 302 is the card-engaging protrusion, the pushing portion 303 is pulled until it cannot be moved. At this time, the positioning component, that is, the main body is located in the above-mentioned first position, and the second matching portion 302 is in a card-engaged state with the first matching portion. By pushing the pushing portion 303 until it cannot be moved, the positioning component, that is, the main body is located in the above-mentioned second position, and the second matching portion 302 is in a separated state with the first matching portion, so as to realize the disassembly between the upper cover 1 and the bottom shell 2.

[0048] Alternatively, if Figure 1 As shown, the first matching portion in the present application includes a protruding section 201 , and a latching groove 202 is formed on the protruding section 201 .

[0049] Since the first matching portion needs to pass through the slot 101 and enter the bearing slot 102 to achieve engagement with the second matching portion 302 , the slot 202 is formed on the raised section 201 , thereby enabling smooth engagement between the slot 202 and the above-mentioned engaging protrusion.

[0050] Alternatively, if Figure 2 Combination Figure 4 As shown, the positioning assembly in the present application also includes an elastic member 4, which is disposed in the bearing groove 102, and one end of the elastic member 4 abuts against the inner wall of the bearing groove 102, and the other end abuts against a side wall of the positioning member 3 away from the pushing portion 303.

[0051] The elastic member 4 in the present application adopts a spring, so that the elastic member 4 can replace the above-mentioned pulling and pushing part 303 to make the main body reach the first position, and the elastic member 4 can keep the main body in the first position at all times.

[0052] When the first matching portion is inserted into the clamping groove 301 of the main body, the end of the protruding section 201 can abut against the second matching portion 302 and push the second matching portion 302 to drive the entire main body to move from the first position to the second position. As the first matching portion continues to move downward, the clamping groove 202 also moves downward, and the elastic member 4 is also continuously compressed. When the clamping groove 202 moves into place, the second matching portion 302 no longer obtains thrust, so that the elastic member 4 can rebound to drive the main body to move from the second position to the first position, thereby achieving the action of the second matching portion 302 being clamped into the clamping groove 202, and achieving a stable connection between the upper cover 1 and the bottom shell 2.

[0053] When the upper cover 1 and the bottom shell 2 need to be disassembled, the pushing portion 303 is pushed to move the main body from the first position to the second position until the second matching portion 302 is separated from the first matching portion, thereby achieving the disassembly between the upper cover 1 and the bottom shell 2. When the disassembly is completed, the pushing portion 303 is released, and the elastic member 4 can automatically push the main body from the second position to the first position.

[0054] It should be noted here that the use of a spring as the elastic member 4 in the present application is only one of the preferred implementations. A columnar or spherical structure formed of an elastic material, such as silicone or rubber, may also be used, which can also achieve the function of automatically moving the main body from the second position to the first position.

[0055] In practical application, such as Figure 2 Combination Figure 4 As shown, the end of the raised section 201 in the present application away from the bottom shell 2 is formed with a first inclined surface, and the second matching portion 302 is formed with a second inclined surface 3021, and the first inclined surface abuts against the second inclined surface 3021 so that the positioning assembly can move from the first position to the second position and compress the elastic member 4.

[0056] The first inclined surface and the second inclined surface 3021 can play a guiding role, so that the downward movement of the first matching portion can smoothly and stably push the second matching portion 302 to move, so as to realize the function of the overall structure.

[0057] Alternatively, if Figure 1 Combination Figure 4As shown, the detachable shell provided by the utility model also includes a baffle 5, an opening 1021 is formed on one side of the bearing groove 102, the positioning component enters the bearing groove 102 through the opening 1021, the baffle 5 is blocked at the opening 1021, and a through hole 501 is formed on the baffle 5 at a position corresponding to the pushing part 303, one end of the pushing part 303 passes through the through hole 501 and protrudes from the side of the baffle 5 away from the upper cover 1.

[0058] By forming the opening 1021 on one side of the bearing groove 102, the positioning assembly can enter the bearing groove 102 through the opening 1021 during the installation phase. The present application sets a baffle 5, and the baffle 5 in the present application can be connected to the upper cover 1 by welding, bonding or hot-melt connection, thereby achieving the purpose of sealing the opening 1021 opened at the position of the upper cover 1 corresponding to the bearing groove 102.

[0059] During the actual assembly, the positioning assembly is first installed into the bearing groove 102, and then the baffle 5 is installed accordingly, so that the push portion 303 passes through the through hole 501 formed on the baffle 5, so as to achieve the overall positioning of the positioning assembly. Finally, the baffle 5 is connected to the upper cover 1 by hot melting to complete the assembly of the upper cover 1. After the assembly is completed, the connection and separation between the upper cover 1 and the bottom shell 2 can be achieved by connecting and separating the first matching portion and the positioning assembly.

[0060] Alternatively, if Figure 1 Combination Figure 3 As shown, the number of positioning components in the present application is multiple, the bearing grooves 102 are arranged one-to-one with the positioning components, and the bearing grooves 102 are distributed circumferentially along the edge of the upper cover 1 toward the bottom shell 2, and the first matching parts are arranged one-to-one with the positioning components.

[0061] It can be understood that since the positioning component in the present application needs to be transferred from the first position to the second position in the supporting groove 102 through the pushing portion 303, the displacement distance of the positioning component from the first position to the second position is the same as the size of the side wall of the pushing portion 303 protruding from the upper cover 1. On the one hand, it can realize the movement of the positioning component, and on the other hand, it can also make the moving distance of the positioning component more precise, avoiding the problem of excessive compression of the elastic member 4 causing damage due to excessive pushing.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
