DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0048] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0049] The sealing structure provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0050] First, the following noun concepts are described:

[0051] Personal care equipment: refers to equipment that can use consumables or care products (such as skin care products, toothpaste, etc.) to provide care functions for users, which includes a body and a container; the body is the part of the equipment that is specifically used to use care products to achieve care functions. Corresponding to different types of personal care equipment, the body can include different functional devices. For example: when the personal care equipment is a massager that automatically applies care products, the body can include an electric massage head for applying care products. When the personal care equipment is an electric toothbrush that can automatically replenish toothpaste, the body can include an electric toothbrush for brushing teeth (which can include a toothbrush head, a control module that controls the operation of the toothbrush head, a drive module, etc.). The embodiments of the present application do not limit the specific structural design of the body and the specific device components included.

[0052] The container is a device part specifically used to store consumables or care products. Different care products can be stored in the container corresponding to different types of personal care devices. For example, when the personal care device is a massager that automatically applies care products, facial creams, lotions, etc. can be stored in the container. When the personal care device is an electric toothbrush that can automatically replenish toothpaste, toothpaste can be stored in the container. The embodiments of the present application do not limit the specific structural design of the container and the types of care products stored.

[0053] In the embodiment of the present application, the buckle structure is applied to the disassembly and installation between the body and the container in the personal care device. According to the actual situation, the personal care device can include any number of bodies and containers, such as one body with one container for storing care products, or one body with multiple containers for storing different types of care products, or one container with multiple bodies with different functions. It can be flexibly arranged according to specific application requirements. Accordingly, no matter which body and container are matched, the buckle structure provided in the embodiment of the present application can be set for the disassembly and installation between each set of bodies and containers. It can be understood that the embodiment of the present application does not limit the type of personal care equipment, the number of bodies and containers included, and the number of buckle structures used, and can be flexibly arranged according to actual needs.

[0054] See also Figure 1 and Figure 2 , the figure shows a personal protection device, including a body 01 and a container 02, and the body 01 and the container 02 are disassembled and assembled through a buckle structure 03. Specifically, the user can remove the container 02 from the body 01 (i.e., unlock it) by applying a force to the buckle structure 03, and when the force is removed, the container 02 can be assembled (i.e., locked) with the body 01.

[0055] See also Figures 2 to 10 An embodiment of the present application provides a buckle structure, including: two buckle parts 1, a pushing part 2 and an elastic part 3.

[0056] The design of two fasteners 1 can ensure that the two fasteners 1 are subjected to balanced forces during operation, thereby improving the working stability. It should be noted that the structures of the two fasteners 1 can be symmetrical or asymmetrical, which is not limited here.

[0057] like Figure 5 , Figure 6 , Figure 8 As shown, the buckle 1 includes: a body 10, and a first force-bearing portion 110 and a second force-bearing portion 120 connected to the body 10;

[0058] by Figure 5 As shown in the figure, for example, the main body 10 of the fastener 1 is bent into a C-shape, that is, the main body 10 is designed to be bent inward, and the corresponding two fasteners 1 can form an O-shaped clamping structure for providing assembly clamping force during the assembly process of the personal protection equipment.

[0059] It should be noted that Figure 5 The example in which the body 10 is bent into a C shape is shown. In actual application scenarios, the body 10 can also be designed to be non-bent, which can be determined according to the shape of the container mouth side locked by the specific snap structure. If the container mouth is square, the body 10 can also be designed to be a corresponding semi-open shape, and the corresponding two snap members 1 can form a mouth-shaped clamping structure. The embodiment of the present application does not specifically limit the shape of the body 10, and does not specifically limit the shape of the clamping structure composed of the two snap members 1.

[0060] The above-mentioned force-bearing part refers to the specific force-bearing part of the buckle 1 when the buckle structure 03 is working. It can be understood that since the first force-bearing part 110 and the second force-bearing part 120 are respectively provided, the clamping structure composed of the two buckles 1, the first force-bearing part 110 and the second force-bearing part 120, can ensure that the force of the clamping structure as a whole is symmetrical and uniform, which is conducive to improving working stability.

[0061] like Figure 7As shown, the pushing member 2 includes a first pushing portion 21 and a second pushing portion 22 , and the pushing portion refers to a portion on the pushing member 2 for applying a specific thrust.

[0062] The first pushing portion 21 and the second pushing portion 22 are used to respectively support the first force-bearing portion 110 and the second force-bearing portion 120 when a force is applied to the pushing member 2, so that the two buckling members 1 move away from each other;

[0063] The above-mentioned push part supports the force-bearing part specifically by applying a force to the push member 2, and the force acts on the push part, and the push part supports the force-bearing part, thereby pushing the two snap members 1 away from each other, so that the two snap members 1 are opened; it is understandable that the force can be directly applied to the push part by the user, such as the user pressing the push part by hand, or it can be applied to the push part by other equipment components, such as the user pressing the disassembly control button on the device, and a control instruction is generated accordingly, and the control instruction controls other components to press the push part. The embodiment of the present application does not limit the implementation method of applying the force to the push part.

[0064] The elastic member 3 is used to release the elastic force that causes the two buckle members 1 to move toward each other when the acting force disappears or is cancelled.

[0065] The elastic member 3 is used to provide a restoring force for the two buckles 1, so that when the push portion pushes the two buckles 1 apart, if the external force disappears, the two buckles 1 can be closed again by the elastic force of the elastic member 3. In other words, the two buckles 1 return to their initial positions when no force is applied by the elastic force generated by the elastic member 3.

[0066] In an optional embodiment, the elastic member 3 is disposed between two buckling members 1 ; and / or the elastic member 3 is disposed on the outer side of the body 10 .

[0067] In an optional embodiment, the elastic member 3 is disposed between the first ends 11 of the two snap members 1; and / or, the elastic member 3 is disposed between the second ends 12 of the two snap members 1; and / or, the elastic member 3 is disposed between the inner sides 104 of the main bodies 10 of the two snap members 1.

[0068] Figure 3 , Figure 4 and Fig.12 The elastic member 3 is arranged between two buckles 1. The elastic member 3 is arranged between the second ends 12 of the two buckles 1. In an optional embodiment, Fig.12 and 13As shown, when the elastic member 3 is arranged between the second ends 12 of the two snap members 1, the two first ends 11 are respectively provided with fixing members 30, and the two ends of the elastic member 3 are respectively connected to the two fixing members 30; when the elastic member 3 is arranged between the second ends 12 of the two snap members 1, the two second ends 12 are respectively provided with fixing members 30, and the two ends of the elastic member 3 are respectively connected to the two fixing members 30.

[0069] Fig.13 The fixing member 30 is shown as a hook disposed on the second end 12 of the buckle 1. Fig.12 As shown, the two ends of the elastic member 3 are hung on two hooks. It should be noted that the fixing member 30 may not be a hook, but may be other components capable of fixing the elastic member 3, which is not limited here. Optionally, the elastic member 3 may be a spring, or may be other components such as a spring sheet that can generate elastic force after a force is applied thereto.

[0070] Optionally, the number of the elastic members 3 can be one or more, that is, one or more elastic members 3 are arranged between two buckles 1 ; and / or one or more elastic members 3 are arranged on the outer side surface 103 of the buckle 1 .

[0071] When an elastic member 3 is provided, for example, an elastic member 3 is provided at the second ends 12 of the two buckle members 1, that is, Figure 3 , 4 In the scenario shown in the figure, an elastic member 3 is provided, and the two ends of the elastic member 3 are respectively fixed on the second ends 12 of the two clips 1, and the two clips 1 are reset by applying an inward pulling force to the two clips 1; or an elastic member 3 is provided at the first ends 11 of the two clips 1; or, an elastic member 3 is provided between the inner sides 104 of the two clips 1.

[0072] When multiple elastic members 3 are provided, multiple elastic members may be provided between two clips 1, including but not limited to: multiple elastic members 3 are provided at the first ends 11 of the two clips 1; multiple elastic members 3 are provided at the second ends 12 of the two clips; one or more elastic members 3 are provided at the first ends 11 of the two clips 1, and one or more elastic members are provided at the second ends 12 of the two clips 1; multiple elastic members 3 are provided on the inner side surfaces 104 of the two clips 1; one or more elastic members 3 are provided at the first ends 11 or the second ends 12 of the two clips 1, and one or more elastic members 3 are provided on the inner side surfaces 104 of the two clips 1. Of course, one or more elastic members 3 can also be provided on the outer side surface 103 of each buckle 1. When the elastic member 3 is provided on the outer side surface 103 of the buckle 1, one end of the elastic member 3 can be fixed on the outer side surface of the buckle 1, and / or the other end can be correspondingly fixed on the inner wall surface of the body of the personal protection device. By providing one or more elastic members 3 on the outer side surfaces 103 of the two buckles 1, when the user cancels the force applied to the buckles 1, the elastic member 3 generates 103 elastic force to reset the two buckles 1, that is, the elastic force that pushes the two buckles 1 to move closer to each other. The embodiment of the present application does not specifically limit the setting method and setting quantity of the elastic member 3. In the embodiment of the present application, the buckle structure 03 includes two buckles 1, a pushing member 2 and an elastic member 3. The two buckles 1 can provide a clamping function. Force-bearing parts are set at both ends of the buckle 1, and the pushing member includes two pushing parts accordingly. When a force is applied to the pushing member, the two force-bearing parts are respectively supported, so that the two buckles 1 move away from each other, and the two buckles are opened, so that the personal protection device can be unlocked. When the force disappears, the two buckles move toward each other under the elastic force of the elastic member 3, and the personal protection device is locked by the clamping function provided by the two buckles 1. The buckle structure provided in the embodiment of the present application simplifies the structural design. Through the linkage between the pushing member and the force-bearing part, the personal protection device can be unlocked and locked by simply applying a force to the pushing member or canceling the force, thereby simplifying the operation, improving the convenience of disassembly and assembly of the personal protection device, and being intelligent.

[0073] In an alternative embodiment, see Figure 8 , Figure 8 1 is a partially enlarged schematic diagram of the first end 11. The first end 11 is provided with a first force-bearing portion 110. The first force-bearing portion 110 includes a first inclined surface 112. That is, the first force-bearing portion 110 can be the first inclined surface 112. Fig. 9 , Fig. 9It is a partially enlarged schematic diagram of the first pushing portion 21, and the first pushing portion 21 includes a second inclined surface 211; the second inclined surface 211 is used to support the first inclined surface 112 when a force is applied to the pushing member 2, and the second inclined surface 211 and the first inclined surface 112 move relative to each other, that is, the first pushing portion 21 is used to support the first force-bearing portion 110 when a force is applied to the pushing member 2, so that the first force-bearing portion 110 (that is, the first inclined surface 112) and the second inclined surface 211 move relative to each other.

[0074] In the embodiment of the present application, the first inclined surface 112 and the second inclined surface 211 cooperate to decompose a vertical lateral force from the thrust. This lateral force is the thrust on the latch 1, which is used to push the latch 1 open. The inclined surface design is adopted to achieve a process in which the first pushing portion 21 pushes the first force-bearing portion 110. The first pushing portion 21 and the first force-bearing portion 110 are relatively displaced in opposite directions along the inclined surface, which is ultimately manifested as the latch 1 being pushed outward to open, that is, the two latches 1 move away from each other.

[0075] See also Fig.10 , Fig.10 is a partial enlarged schematic diagram of the second end 12, the second end 12 is provided with a second force-bearing portion 120, and the second force-bearing portion 120 includes a third inclined surface 121, that is, at this time, the second force-bearing portion 120 can be the third inclined surface 121; see Fig.11 , Fig.11 It is a partially enlarged schematic diagram of the second pushing portion 22, and the second pushing portion 22 includes a fourth inclined surface 221; the third inclined surface 121 is used to support the fourth inclined surface 221 when a force is applied to the pushing member 2, and the third inclined surface 121 and the fourth inclined surface 221 move relative to each other, that is, the second pushing portion 22 is used to support the second force-bearing portion 120 when a force is applied to the pushing member 2, so that the second force-bearing portion 120 (that is, the third inclined surface 121) and the fourth inclined surface 221 move relative to each other.

[0076] In the embodiment of the present application, the cooperation principle between the third inclined surface 121 and the fourth inclined surface 221 is the same as the cooperation principle between the second inclined surface 211 and the first inclined surface 112 mentioned above, which can be understood by reference and will not be repeated here.

[0077] In an alternative embodiment, see Figure 5 , Figure 8 and Fig.10 The buckle 1 further includes a first end 11 and a second end 12 , the body 10 is connected to the first end 11 and the second end 12 , the first end 11 is provided with a first force-bearing portion 110 , and the second end 12 is provided with a second force-bearing portion 120 .

[0078] The first end 11 is also provided with a stop surface 111 connected to the first inclined surface 112, and the first inclined surface 112 and the stop surface 111 have or form a first inclined angle, and the angle of the first inclined angle is 100°~165°; the second end 12 is also provided with an outer wall surface 122 connected to the third inclined surface 121, and the third inclined surface 121 and the outer wall surface 122 have or form a second inclined angle, and the angle of the second inclined angle is 15°~80°.

[0079] In the embodiment of the present application, the function of the stop surface 111 is to provide a travel limit for the distance that the latch 1 is pushed, that is, when the first pushing portion 21 continues to push into the interior of the latch 1 until the stop surface 111 and the first pushing portion 21 abut against each other, at this time, the advancement of the first pushing portion 21 is blocked by the stop surface 111, thereby achieving the maximum opening degree of the latch 1.

[0080] There is a first inclined angle (i.e. Figure 8 The angle A indicated in the figure is 100° to 165° (the angle range includes 100° and 165°). The third inclined surface 121 and the outer wall surface 122 have a second inclined angle (i.e. Fig.10 The angle B indicated in the figure is 15° to 80° (the angle range includes 15° and 80°). The inclination of the inclined surface in the force-bearing part is designed within the above angle range to provide a good matching effect between the pushing part and the force-bearing part.

[0081] It should be noted that the angle of the first inclination angle can also be 120°~150° (the angle range includes 120° and 150°), and the angle of the second inclination angle can also be 30°~60° (the angle range includes 30° and 60°). By adopting this further angle range, the coordination effect between the pushing part and the force-bearing part can be better.

[0082] In an alternative embodiment, see Figure 3 and Figure 7 The pushing member 2 also includes: a force-bearing member 23 and a connecting member 24; the force-bearing member 23 is fixedly connected to the first pushing portion 21; the connecting member 24 is respectively fixedly connected to the first pushing portion 21 and the second pushing portion 22; the force-bearing member 23 is used to link the first pushing portion 21 to support the first force-bearing portion 110 when subjected to a force, and to link the second pushing portion 22 to support the second force-bearing portion 120 through the connecting member until the force-bearing member 23 is against the stop surface 111.

[0083] In the embodiment of the present application, in addition to the pushing part, the pushing member 2 is also provided with a force-bearing member 23 and a connecting member 24. The force-bearing member 23 is used to bear external force and transmit the external force to the first pushing part 21, and the connecting member 24 is used to further transmit the external force to the second pushing part 22. In this way, when the force-bearing member 23 is acted upon by an external force, the force-bearing member 23, the first pushing part 21, the connecting member 24, and the second pushing part 22 move synchronously under the push of the external force. Optionally, the force-bearing member 23 can be a component such as a button or a key to which an external force / acting force is applied. In addition, the force-bearing member 23 can be set to be exposed to the fuselage, so that it can not only be seen by the user, but also can be better operated by the user (for example, pressed).

[0084] It should be noted that the embodiment of the present application does not limit the specific shape of the connecting member 24, as long as it can achieve the transmission of force from the first pushing portion 21 to the second pushing portion 22. Figure 7 In the scenario shown in the figure, the connecting member 24 adopts the same shape as the clamping structure composed of the two snap fasteners 1. This is because in the actual application scenario, the clamping structure composed of the two snap fasteners 1 is generally used to clamp the structural components on the device, and the pusher 2 needs to be used in conjunction with the snap fastener 1. Therefore, the distance between the pusher 2 and the clamped structural component may be very close. Therefore, the connecting member 24 can be adaptively designed to be the same shape as the clamping structure composed of the two snap fasteners 1, so that it can be simultaneously sleeved on the clamped structural component, while realizing the function of the snap fastener structure, saving the internal space of the device. Of course, the connecting member 24 can also be designed to be a different shape from the clamping structure composed of the two snap fasteners 1, which can be flexibly adjusted according to the actual application scenario requirements. In the embodiment of the present application, the two snap fasteners 1 are determined to be annular due to the formation of the bottle mouth of the container 02. The connecting member 24 can be set to annular along with the snap fastener 1, or it can not be set to annular.

[0085] In an alternative embodiment, see Figure 8 and Fig.10 The first end 11 is further provided with a first guide surface 113 , and the first guide surface 113 is connected to the first inclined surface 112 ; and / or, the second end 12 is further provided with a second guide surface 123 , and the second guide surface 123 is connected to the third inclined surface 121 .

[0086] In an embodiment of the present application, a guide surface is provided on the force-bearing portion, and the function of the guide surface is to provide a guide for the relative displacement between the pushing portion and the force-bearing portion when the buckle structure is working.

[0087] In an alternative embodiment, see Figure 8, the first end 11 is also provided with a transition surface 114; the first guide surface 113 is connected to the first inclined surface 112 through the transition surface 114; the first guide surface 113 and the transition surface 114 are perpendicular to each other. Optionally, the first guide surface 113 and the transition surface 114 may not be arranged to be perpendicular to each other. In the embodiment of the present application, considering that the first force-bearing portion 110 is the first position on the buckle 1 to contact and bear force with the pusher 2, a transition surface 114 perpendicular to the first guide surface 113 is added to allow the buckle 1 to bear force better and achieve a more stable force-bearing structure.

[0088] That is to say, the first end 11 includes a first inclined surface 112 (i.e., the first force-bearing portion 110 ), a stop surface 111 , a first guide surface 113 and a transition surface 114 , while the second end 12 includes a third inclined surface 121 (i.e., the second force-bearing portion 120 ), a second guide surface 123 , and an outer wall surface 122 .

[0089] It should be noted that the first end 11 may not be provided with a transition surface 114, but may be provided with a first guide surface 113, and the first guide surface 113 is directly connected to the first inclined surface 112; and the second end 12 may be provided with a transition surface between the third inclined surface 121 and the second guide surface 123, and the third inclined surface 121 is connected to the second guide surface 123 through the transition surface.

[0090] Of course, the first end 11 and the second end 12 may not be provided with guide surfaces, that is, the first end 11 is not provided with the first guide surface 113, and the second end 12 is not provided with the second guide surface 123, but only the first force-bearing portion 110 (that is, the first inclined surface 112) and the second force-bearing portion 120 (that is, the third inclined surface 121) are provided.

[0091] In an alternative embodiment, see Figure 5 and Fig.12 The body 10 includes a top surface 101 , a bottom surface 102 , an outer side surface 103 and an inner side surface 104 .

[0092] See also Figure 5 and Figure 6, the buckle 1 also includes a buckle part 100, which is arranged on the inner side surface, and the buckle part 100 is a protrusion or a groove. The buckle part 100 is a part of the buckle 1, which is arranged on the inner side surface 104 of the buckle 1, and fixes the device (such as a container) in the fuselage. The device can be provided with a corresponding groove or protrusion that cooperates with the buckle 1. Specifically, a protrusion or a groove is arranged on the inner side surface 104 of the buckle 1, and correspondingly, a groove or a protrusion is arranged at a corresponding position on the outer side surface of the bottle mouth of the container. When the two buckles 1 move toward each other, the protrusion or groove of each buckle 1 is adapted to connect with the corresponding groove or protrusion on the outer side surface of the bottle mouth of the container. It should be noted that the buckle parts 100 of the two buckles 1 can be protrusions or grooves at the same time; or one buckle 1 can be a protrusion and the other buckle 1 can be a groove, in which case the corresponding positions on the outer side surface of the bottle mouth of the container are one groove and one protrusion.

[0093] The present application embodiment also provides a personal protection device, including a body 01 and a container 02. For details, please refer to Figure 1 , Figure 2 The personal protection device also includes the snap-fit ​​structure as described above; the container 02 is detachably connected to the body 01 via the snap-fit ​​structure 03.

[0094] In an optional embodiment, an assembly end (specifically, a delivery port for delivering care products in the container) is provided on the container 02, and a connecting portion (such as a groove or a protrusion) can be provided on the outer surface of the assembly end for cooperating with the snap portion 100 on the snap member 1.

[0095] The above-mentioned grooves or protrusions are used to assist the buckle structure in clamping the assembly end, and can also assist the buckle structure in positioning, ensuring that the buckle structure can work in the correct position.

[0096] In an optional embodiment, the elastic member 3 in the buckle structure includes two elastic sub-members, one end of one of the elastic sub-members is fixed between the outer side surface of the body 10 of one of the buckles 1 and the inner wall surface of the fuselage 01, and one end of the other elastic sub-member is fixed between the outer side surface of the body 10 of the other buckle 1 and the inner wall surface of the fuselage 01. That is, by applying a thrust force to the two buckles 1 so as to push the two buckles 1 inward, the two buckles 1 are reset.

[0097] In an alternative embodiment, see Fig.14 The personal protection device also includes a support frame 4; the support frame 4 is used to fix the buckle structure in the fuselage 01.

[0098] In an optional embodiment, the support frame 4 includes a base 41 and a support member 42; the base 41 is used to support the buckle structure; the support member 42 is arranged on the base 41, and the support member 42 surrounds the buckle structure.

[0099] Optionally, after the body 01 and the container 02 are assembled together through the snap-fit ​​structure 03, the base 41 is sleeved on the assembly end of the container.

[0100] In the embodiment of the present application, the function of the support frame 4 is to support the buckle structure and assist the buckle structure in working. Specifically, the base 41 is used to support the buckle structure, and the support member 42 surrounds the buckle structure to protect the buckle structure. Furthermore, since the two buckle members 1 will move away from each other when the buckle structure is working, the support member 42 can play the role of providing a travel limit for the buckle 1.

[0101] See also Fig.15 , the figure shows a scene where the support frame 4 and the buckle structure are assembled together.

[0102] It should be noted that the embodiments of the present application do not limit the specific structure and quantity of the supporting members. Fig.14 and Fig.15 The figure shows a scenario where four strip-shaped support members 42 are provided. In some other application scenarios, it is also possible to consider providing an integral curved support member 42 to surround the buckle structure.

[0103] In an alternative embodiment, see Fig.14 A first assembly structure 421 is provided on the support member 42, and a second assembly structure (not shown in the figure) is provided on the fuselage; when the fuselage and the container are assembled, the first assembly structure 421 cooperates with the second assembly structure.

[0104] In the embodiment of the present application, the support frame 4 can further provide an assembly auxiliary function, specifically, through the first assembly structure 421 on the support member 42, so as to further improve the assembly reliability.

[0105] In an optional implementation, the first assembly structure 421 is a groove, and the second assembly structure is a protrusion; or, the first assembly structure 421 is a protrusion, and the second assembly structure is a groove.

[0106] like Fig.14 As shown, the first assembly structure 421 is a protrusion, and a protrusion is provided on each support member 42. It can be understood that the embodiment of the present application does not limit the number of first assembly structures 421, and multiple first assembly structures 421 can also be provided on each support member 42 according to actual needs. In the embodiment of the present application, the support frame 4 is provided with four support members 42, and each support member 42 is provided with a first assembly structure 421, that is, there are four first assembly structures; the four support frames can be symmetrically arranged or asymmetrically arranged; the number of support members 42 provided on the support frame 4 may not be four, as long as the support frame 4 can be fixedly connected to the fuselage 01, and the buckle structure 03 can be fixed in the fuselage 01.

[0107] The embodiment of the present application is provided with a buckle structure 03. When the user needs to unlock the container 02 of the personal protection device from the body 01 or wants to insert the container 02 into the body 01, the user can press the force-bearing member 23 (e.g., a button) of the pushing member 2 that is visible (i.e., exposed) on the outer surface of the body 01. At this time, the force-bearing member 23 is subjected to the force generated by pressing, and the first pushing part 21, the connecting member 24, and the second pushing part 22 are moved together. The second inclined surface 211 of the first pushing part 21 and the fourth inclined surface 221 of the second pushing part 22 respectively support the first force-bearing part 110 ( The first inclined surface 112) and the second force-bearing portion 120 (i.e., the third inclined surface 121) make the two buckles 1 move away from each other to release the container 02 fixed (i.e., clamped) by the two buckles 1; when the two buckles 1 move away from each other, the elastic member 3 generates elastic force, which can be generated by stretching or squeezing the elastic member 3; the two buckles 1 move toward each other through the elastic force generated by the elastic member 3, locking / fixing the container 02 inserted into the body 01 in the body 01. By using the buckle structure of the present application, the structure is simple, and it is convenient to unlock and lock the container (i.e., easy to disassemble and assemble), and it is intelligent.
