Description

Technical Field

[0001] The present application relates to the technical field of clothing treatment, and more particularly, to a vibration damping component and a clothing treatment device. Background Art

[0002] Common clothing treatment devices at present, such as a pulsator washing machine, generally include a box body and a drum assembly disposed in the box body. The drum assembly includes an outer drum and an inner drum rotatably disposed in the outer drum. During washing and dehydration, the inner drum rotates relative to the outer drum, causing the clothing and the washing water to act on each other to achieve the purpose of washing or dehydrating the clothing. However, due to the unevenness of the load, the drum assembly will swing significantly under the action of the eccentric force. Especially in the low-speed dehydration stage, the displacement of the drum assembly is the largest, and it is easy to hit the box body.

[0003] For this reason, generally, several vibration damping components are suspended between the outer drum and the box body. A connecting rod is provided on the outer drum or the box body, and the connecting rod is connected to the box body or the drum body through a fixing member. During actual assembly, it is necessary to first pass the connecting rod through the through hole of the vibration damping component, then connect the fixing member to the end of the connecting rod, and then connect the fixing member to the box body or the drum body. That is to say, the vibration damping component must be manufactured together with the connecting rod. When handling, detecting on the production line or when the user uses it at home, if a certain component of the vibration damping component is damaged, the entire vibration damping component has to be scrapped together, and it is necessary to disassemble and assemble the entire drum assembly for replacement, which is time-consuming and laborious, and the maintenance cost is high.

[0035] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0036] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and therefore specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0037] Although the terms second, first, first, etc. may be used in the text to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another region, layer, or section. Unless the context clearly indicates otherwise, terms such as "second", "first", and other numerical terms do not imply an order or sequence when used in the text. Thus, the second element, component, region, layer, or section discussed below may be referred to as the first element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0038] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure is flipped, an element described as "below" or "beneath" another element or feature will then be oriented as "above" or "over" the other element or feature. Thus, the exemplary term "below" can include both the upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are accordingly interpreted.

[0039] Figure 1 Schematic perspective view of the three-dimensional structure of a vibration damping assembly according to an embodiment of the present application.

[0040] Refer to Figure 1 , an embodiment of the present application provides a vibration damping assembly 100, which is applied to a laundry treatment device. The laundry treatment device includes a cabinet, a connecting rod 400, and a drum assembly disposed in the cabinet. At least a part of the connecting rod 400 is disposed on the cabinet and / or the drum assembly. The vibration damping assembly 100 is connected between the cabinet and the drum assembly. Among them, the vibration damping assembly 100 is formed with a through hole 110, and the connecting rod 400 is adapted to pass through the through hole 110 to connect the vibration damping assembly 100 to the cabinet 200 and / or the drum assembly 300. At least one opening 111 is formed on the circumferential edge of the through hole 110. The vibration damping assembly 100 includes a locking member 13, and at least a part of the locking member 13 is disposed outside the opening 111. In the first state, at least a part of the locking member 13 closes the opening 111; in the second state, the locking member 13 opens the opening 111.

[0041] The drum assembly of a laundry treatment device generally includes an outer drum and an inner drum rotatably disposed within the outer drum. The inner drum is hollow to form a washing chamber. Water outlet holes are provided on the peripheral wall of the inner drum, and the inner drum can discharge washing water to the outer drum through the water outlet holes. A waste water discharge port is provided at the bottom of the outer drum, and the washing water is discharged out of the machine body through a drainage assembly connected to the waste water discharge port. During the cleaning and dehydration processes of the laundry treatment device, the rotational speed of the inner drum gradually increases, and the eccentric load caused by unbalanced laundry gradually increases with the increase in rotational speed. The outer drum will inevitably vibrate. Especially in the start-up stage of dehydration, when the excitation force fundamental frequency corresponding to the rotational speed of the laundry treatment device is close to the natural frequency of the whole machine, the outer drum resonates, and the amplitude significantly increases, that is, the lateral vibration displacement of the outer drum is the largest, and it is easy to hit the cabinet. Therefore, a vibration damping assembly 100 is required to provide a damping force in the horizontal direction or an approximately horizontal direction, reduce the lateral vibration displacement of the drum assembly in the start-up stage of dehydration, and reduce the possibility of the drum assembly hitting the cabinet.

[0042] In the related art, a connecting rod 400 is provided on the cabinet or the outer drum, and the connecting rod 400 is connected to the vibration damping assembly 100. During the actual assembly process, it is necessary to first pass the connecting rod 400 through the through hole of the vibration damping assembly 100 and then connect the connecting rod 400 to the cabinet or the outer drum. That is to say, the vibration damping assembly 100 must be manufactured together with the connecting rod 400. When handling, detecting on the production line, or when the user uses it at home, if a certain component of the vibration damping assembly 100 is damaged, the entire vibration damping assembly 100 has to be scrapped, and it is time-consuming and laborious to disassemble and assemble the entire drum assembly for replacement, and the maintenance cost is high.

[0043] Therefore, in this embodiment, a through hole 110 is formed in the vibration damping assembly 100, and at least one opening 111 is formed on the circumferential edge of the through hole 110. The number of openings 111 can be one, or two or more. The opening 111 can increase the elastic deformation amount of the through hole 110 and prevent the connecting rod 400 from being stuck by the through hole 110 during vibration. The connecting rod 400 can be first assembled with the cabinet or the drum assembly, and then the connecting rod 400 is installed into the through hole 110 through the opening 111 to connect the vibration damping assembly 100 to the cabinet or the drum assembly. In this way, the vibration damping assembly 100 can be separately manufactured from the connecting rod 400, and the assembly method is more flexible, convenient, and fast. Even if a certain component of the vibration damping assembly 100 is damaged, only the connecting rod 400 needs to be taken out of the through hole 110 along the opening 111, and then the damaged component is replaced, without disassembling and assembling the entire drum assembly for replacement, which saves time and effort and reduces the maintenance cost.

[0044] It should be noted that when only one through hole 110 is provided on the damping assembly 100, one damping assembly 100 can be matched with one connecting rod 400. In one example, one end of the connecting rod 400 is connected to the box body, the other end of the connecting rod 400 is connected to the cylinder assembly, and the connecting rod 400 is installed into the through hole 110 through the opening 111 of the damping assembly 100; in this embodiment, one end of the connecting rod 400 is connected to the box body, the other end is connected to the cylinder assembly, one end of the damping assembly 100 is connected to the connecting rod 400, and the other end is fixed to the box body or the cylinder assembly, which can not only realize the stable connection of the damping assembly 100, but also play the damping effect. In another example, one end of the connecting rod 400 is connected to one of the box body and the cylinder assembly, the other end of the connecting rod 400 is a free end, the outer diameter of the free end is greater than the inner diameter of the through hole 110, the connecting rod 400 is installed into the through hole 110 through the opening 111 of the damping assembly 100, and the other of the box body and the cylinder assembly is connected to the damping assembly 100 through a fastener to connect the damping assembly 100 between the box body and the cylinder assembly. In this embodiment, the other end of the connecting rod 400 can be connected to the same box body or one of the cylinder assemblies as one end of the connecting rod 400. At this time, both ends of the connecting rod 400 are connected to the box body or the cylinder assembly, and the middle part of the connecting rod 400 passes through the through hole 110 of the damping assembly 100 to realize the installation. In another example, two through holes 110 can also be provided on the damping assembly 100. Correspondingly, one damping assembly 100 can be matched with two connecting rods 400. For example, one end of one connecting rod 400 is connected to the top of the box body, one end of the other connecting rod 400 is connected to the top of the cylinder assembly, the other ends of the two connecting rods 400 are both free ends, and the two connecting rods 400 are respectively installed into the corresponding through holes 110 through their respective openings 111 to connect the damping assembly 100 between the box body and the cylinder assembly. In this embodiment, it can also be that both ends of one connecting rod 400 are connected to one of the box body or the cylinder assembly, and both ends of the other connecting rod 400 are connected to the other of the box body or the cylinder assembly, and the middle parts of the two connecting rods 400 respectively pass through the two through holes 110 of the damping assembly 100.

[0045] In addition, in order to reduce the possibility that the damping assembly 100 disengages from the through hole 110 along the opening 111 during the vibration of the cylinder assembly, the damping assembly 100 further includes a locking member 13. The locking member 13 is disposed outside the opening 111, and the locking member 13 is used to open or close the opening 111. In the first state, the locking member 13 opens the opening 111, and the connecting rod 400 is installed into the through hole 110 through the opening 111 to complete the assembly of the damping assembly 100 and the connecting rod 400, or the connecting rod 400 is taken out of the through hole 110 along the opening 111 to disassemble the connecting rod 400 and the damping assembly 100; in the second state, the locking member 13 closes the opening 111 to reduce the possibility that the connecting rod 400 disengages from the through hole 110 along the opening 111 during use.

[0046] The vibration damping assembly 100 according to an embodiment of the present application can be cooperated with the connecting rod 400 and connected between the cabinet and the drum assembly of the laundry treatment device, and at least a part of the connecting rod 400 is arranged on the cabinet and / or the drum assembly. By forming a through hole 110 on the vibration damping assembly 100 and forming at least one opening 111 on the circumferential edge of the through hole 110, after the connecting rod 400 is assembled with the cabinet and / or the drum assembly, the connecting rod 400 can be installed into the through hole 110 through the opening 111, so that the vibration damping assembly 100 and the connecting rod 400 can be separately manufactured and the assembly is convenient and fast, and the maintenance cost is low. In addition, the vibration damping assembly 100 further includes a locking member 13 arranged outside the opening 111. When the locking member 13 opens the opening 111, the connecting rod 400 can be assembled into the through hole 110 through the opening 111, or the connecting rod 400 can be taken out of the through hole 110 through the opening 111; when the locking member 13 closes the opening 111, the possibility of the connecting rod 400 coming out of the through hole 110 during use can be reduced, and the reliability of the vibration damping assembly 100 can be improved.

[0047] Figure 2 For Figure 1 the structural schematic diagram of the vibration damping assembly shown in another perspective.

[0048] In some embodiments, the vibration damping assembly 100 includes a first connecting portion 11, and the through hole 110 and the locking member 13 are arranged on the first connecting portion 11. Refer to Figure 2 , the connecting rod 400 of the embodiment of the present application is installed into the through hole 110 through the opening 111, so that the connecting rod 400 is connected to the first connecting portion 11, and then the first connecting portion 11 is connected to any one of the cabinet and the drum assembly. And the other one of the cabinet and the drum assembly is connected to the vibration damping assembly 100 through a fastener.

[0049] In some embodiments, the vibration damping assembly 100 further includes a first moving member 1 and a second moving member 2. The first moving member 1 and the second moving member 2 can relatively rotate within a preset angle to generate a damping force, and the first connecting portion 11 is arranged on the first moving member 1 and / or the second moving member 2.

[0050] Specifically, in one example, the first moving member 1 further includes a first main body portion 12 connected to the first connecting portion 11, and the second moving member 2 further includes a second connecting portion 21 and a second main body portion 22 connected to the second connecting portion 21. The first connecting portion 11 is used to connect to either the box body or the cylinder assembly, and the second connecting portion 21 is used to connect to the other of the box body and the cylinder assembly. The first main body portion 12 is pivotally connected to the second main body portion 22 so that the first moving member 1 and the second moving member 2 can relatively rotate within a preset angle to generate a damping force, reduce the lateral vibration displacement of the cylinder assembly during the dehydration start-up stage, and reduce the possibility of the cylinder assembly hitting the box body.

[0051] In another example, the first connecting portion 11 and the second connecting portion 21 have the same structure, that is, the first connecting portion 11 is provided on the first moving member 1 and the second moving member 2. At this time, a vibration damping assembly 100 has two through holes 110 and is equipped with two connecting rods 400. The middle portions of the two connecting rods 400 respectively pass through the two through holes 110. In another example, the first connecting portion 11 is provided on the second moving member 2, and its structure is similar to that of the first connecting portion 11 provided on the first moving member 1, so it will not be elaborated here.

[0052] Optionally, at least one of the first moving member 1 and the second moving member 2 can be a plastic part, and the material can be acrylonitrile-butadiene-styrene copolymer (Acrylonitrile Butadiene Styrene, abbreviated as ABS), polyoxymethylene (Polyoxymethylene, abbreviated as POM), etc., which are light in weight and convenient for mass production.

[0053] Figure 3 For Figure 2 the structural schematic diagram of the first connecting portion in the shown vibration damping assembly.

[0054] In some embodiments, the first connecting portion 11 is further provided with a guiding port 112, and the guiding port 112 extends from the opening 111 in a direction away from the through hole 110. At least a part of the locking member 13 is disposed outside the guiding port 112.

[0055] Refer to Figure 3 , the guiding port 112 of the first connecting portion 11 extends from the opening 111 in a direction away from the through hole 110. The guiding port 112 can increase the path of the connecting rod 400 vibrating back and forth in the through hole 110 of the first connecting portion 11, buffer the impact force received by the connecting rod 400 during vibration, prevent the periphery of the through hole 110 from being damaged due to stress concentration when the impact force is too large, and at the same time be used to guide the connecting rod 400 to be installed into the through hole 110 through the opening 111. At least a part of the locking member 13 is disposed outside the guiding port 112 to close the guiding port 112 and reduce the possibility of the connecting rod 400 disengaging from the guiding port 112.

[0056] In some embodiments, the guiding opening 112 includes a straight section 112a and an open section 112b. The straight section 112a is disposed between the opening 111 and the open section 112b. The first connecting portion 11 includes a first rib 1121 and a second rib 1122 that form the guiding opening 112. The straight sections 112a of the first rib 1121 and the second rib 1122 are arranged in parallel, and the open sections 112b of the first rib 1121 and the second rib 1122 are arranged to gradually expand in a direction away from the straight section 112a.

[0057] As Figure 3 shown, the straight sections 112a of the first rib 1121 and the second rib 1122 are arranged in parallel, which is mainly used to buffer the impact force received by the connecting rod 400 during vibration and prevent the periphery of the through hole 110 from being damaged due to stress concentration when the impact force is too large. The open sections 112b of the first rib 1121 and the second rib 1122 are arranged to gradually expand in a direction away from the straight section 112a, which is used to guide the connecting rod 400 to be installed into the through hole 110 through the opening 111, thereby improving the assembly efficiency of the connecting rod 400 and the vibration damping assembly 100.

[0058] In some embodiments, the locking member 13 includes a first locking portion 131 and a second locking portion 132. The first locking portion 131 is disposed at the open section 112b of the first rib 1121. The first locking portion 131 and the second locking portion 132 are located on both sides of the opening 111 along the extending direction of the guiding opening 112, and the first locking portion 131 is connected to the second locking portion 132 to at least partially close the opening 111.

[0059] Optionally, the locking member 13 is a plastic part, and its material can be ABS or POM. Optionally, the locking member 13 and the first connecting portion 11 are an integral structural part, and the two are formed by an injection molding process to improve the connection strength between the locking member 13 and the first connecting portion 11. Optionally, the locking member 13 and the first connecting portion 11 are separately provided, and the two are connected into one body by means of bonding, threaded connection, etc. Optionally, the first locking portion 131 and the second locking portion 132 of the locking member 13 are detachably connected, which can realize multiple assembly and disassembly, saving time and effort and further reducing the maintenance cost.

[0060] In some embodiments, the first connecting portion 11 includes an inner peripheral structure and an outer peripheral structure. The inner peripheral structure forms the through hole 110. The outer peripheral structure is spaced apart from the outer peripheral side of the inner peripheral structure, and a through groove 116 is formed between the inner peripheral structure and the outer peripheral structure. A reinforcing rib 115 is connected between the inner peripheral structure and the outer peripheral structure, and the first rib 1121 is connected to the end of the outer peripheral structure.

[0061] As Figure 3As shown, when the wall thickness of the through hole 110 is too thick, it is not easy to undergo elastic deformation, and the connecting rod 400 is likely to get stuck when moving within the through hole 110. Therefore, a through groove 116 is further formed between the inner peripheral structure and the outer peripheral structure, increasing the deformable amount on the circumferential side of the through hole 110, preventing the connecting rod 400 from getting stuck when moving within the through hole 110, and also facilitating the installation of the connecting rod 400 into the through hole 110 along the deformed guiding opening 112. Additionally, when the wall thickness of the through hole 110 is too thin, the strength is insufficient, and the connecting rod 400 is likely to break the through hole 110 when moving within the through hole 110. Therefore, a reinforcing rib 115 is connected between the inner peripheral structure and the outer peripheral structure of the first connecting portion 11. The reinforcing rib 115 can increase the structural strength on the circumferential side of the through hole 110, preventing the through hole 110 from being broken by the connecting rod 400.

[0062] Further, the first rib 1121 of the guiding opening 112 is connected to the end of the outer peripheral structure. Herein, the "end of the outer peripheral structure" means that the outer peripheral structure of the first connecting portion 11 is disconnected by the guiding opening 112 into a non-closed structure, such that the first rib 1121 forming the guiding opening 112 is connected to the end of the outer peripheral structure, while the second rib 1122 is disconnected from the end of the outer peripheral structure. The first rib 1121 can increase the structural strength on the circumferential side of the through hole 110, preventing the through hole 110 from being broken by the connecting rod 400.

[0063] In some embodiments, the outer peripheral structure includes recesses 113 and protrusions 114 arranged alternately in the circumferential direction, and the reinforcing rib 115 is connected between the inner peripheral structure and the protrusion 114.

[0064] As Figure 3 shown, the outer peripheral surface of the first connecting portion 11 includes recesses 113 and protrusions 114 arranged alternately in the circumferential direction. A plurality of reinforcing ribs 115 are provided between the circumferential side of the through hole 110 and the protrusion 114. The open section 112b of the first rib 1121 is connected to the protrusion 114, and the open section 112b of the second rib 1122 is disconnected from the protrusion 114. Through grooves 116 are respectively formed between the first rib 1121 and the reinforcing rib 115 and between two adjacent reinforcing ribs 115. A blind groove is formed between the second rib 1122 and the reinforcing rib 115. The blind groove can improve the connection strength between the first connecting portion 11 and the first main body portion 12. The through groove 116 can reduce the wall thickness of the through hole 110, increase the deformable amount on the circumferential side of the through hole 110, prevent the connecting rod 400 from getting stuck when moving within the through hole 110, and also facilitate the installation of the connecting rod 400 into the through hole 110 along the deformed guiding opening 112. Additionally, the alternately arranged recesses 113 and protrusions 114 on the outer peripheral surface of the first connecting portion 11 have a compact structure, which can enhance the fatigue resistance of the long-term deformation of the through hole 110 and extend the service life of the vibration damping assembly 100.

[0065] In some embodiments, the first locking portion 131 includes a strip 1311 disposed on one side of the guide opening 112 and a head 1312 connected to the strip 1311 , and the second locking portion 132 is connected to the head 1312 .

[0066] like Figure 2 and Figure 3 As shown, when the locking member 13 closes the opening 111, one end of the strip 1311 is connected to the open section 112b of the first rib 1121, and the other end of the strip 1311 is detachably connected to the second locking portion 132 on the outer side of the open section 112b of the second rib 1122 through the head 1312. Optionally, the head 1312 is a pin, and the second locking portion 132 includes a mounting hole and a guide groove connected to the mounting hole and gradually expanded, the mounting hole is adaptively connected to the pin, and the guide groove is used to guide the pin to be installed into the mounting hole, thereby improving the assembly efficiency of the locking member 13. Optionally, the central axis of the mounting hole is substantially parallel to the central axis of the through hole 110, and the mounting hole is adaptively connected to the pin, and the opening 111 can be closed by the friction between the two. In the absence of external force, the pin is difficult to disengage from the mounting hole, thereby improving the reliability of the locking member 13.

[0067] In some embodiments, a limiting platform 117 is provided on the outer peripheral side of the first connecting portion 11, and the limiting platform 117 is located on the outer side of the second rib 1122, the second locking portion 132 is provided on the limiting platform 117, and the second locking portion 132 is a groove and / or a blind hole that cooperates with the head 1312.

[0068] like Figure 3 As shown, the first rib 1121 of the guide opening 112 is connected to the protrusion 114, the second rib 1122 is disconnected from the protrusion 114, the side of the second rib 1122 facing the guide opening 112 is the inner side, and the side away from the guide opening 112 is the outer side. The limiting platform 117 is located on the outer side of the second rib 1122, and the strip 1311 is connected between the first rib 1121 and the limiting platform 117 in an arc shape, which can improve the structural strength of the first connecting part 11. At the same time, the second locking part 132 is arranged on the limiting platform 117. The second locking part 132 includes a mounting hole and a guide groove connected to the mounting hole and gradually expanded, which can prevent the locking member 13 from breaking the second rib 1122 and improve the connection strength of the locking member 13.

[0069] In some embodiments, an oil storage tank is provided on the wall of the through hole 110. The oil storage tank can be filled with lubricating oil or grease, which can reduce the friction of the connecting rod 400 during the swinging process, reduce the wear of the through hole 110, and further extend the service life of the vibration reduction assembly 100.

[0070] Figure 4 is a schematic diagram of the three-dimensional structure of a vibration reduction assembly according to another embodiment of the present application. Figure 5 forFigure 4 Schematic structural diagram of the first connecting portion in the damping assembly shown

[0071] Refer to Figure 4 and Figure 5 , the damping assembly 100 of another embodiment of the present application is similar in structure to the damping assembly 100 shown Figures 1 to 3 , except that the structure of the locking member 13 is different

[0072] Specifically, the first locking portion 131 includes a strip 1311 disposed on one side of the first guiding opening 112 and a head 1312 connected to the strip 1311, and the second locking portion 132 is connected to the head 1312

[0073] The first locking portion 131 further includes wing portions 1313 and / or elastic portions 1314 connected to the rear end of the head 1312 and connected to the head 1312. The cross-sectional area of the rear end of the head 1312 is larger than the cross-sectional area of the front end of the head 1312. The wing portions 1313 adjust the outer diameter of the head 1312 through the elastic portions 1314, and the second locking portion 132 is a blind hole adapted to the head 1312

[0074] As Figure 5 shown, in one example, the head 1312 is arranged in an arrow-like structure, the wing portions 1313 are arranged in an arc-shaped thin-wall structure, and the cross-sectional area of the rear end of the head 1312 is larger than the cross-sectional area of the front end of the head 1312. Herein, the "front end" refers to the end of the head 1312 away from the wing portions 1313, the "rear end" is arranged opposite to the "front end", and the "cross-section" refers to the plane obtained by intercepting the front end or the rear end of the head 1312 by a plane perpendicular to the axis of the head 1312. Two symmetrically arranged elastic portions 1314 are provided between the rear end of the head 1312 and the wing portions 1313. The elastic portions 1314 are of thin-wall structure. An operator can manually or use a tool to clamp the two ends of the wing portions 1313 to shorten the distance between the two elastic portions 1314, thereby reducing the outer diameter of the head 1312, so as to facilitate inserting the head 1312 into the blind hole of the second locking portion 132. By releasing the two ends of the wing portions 1313, the head 1312 can be clamped in the blind hole to enable the locking member 13 to achieve the effect of closing the opening 111. When it is necessary to open the opening 111, the operator can manually or use a tool to clamp the two ends of the wing portions 1313 again to reduce the outer diameter of the head 1312, and the head 1312 can be taken out from the blind hole

[0075] In another example, the first locking portion 131 includes a head 1312 and wing portions 1313 located at the rear end of the head 1312. The number of the wing portions 1313 can be two. The two wing portions 1313 are symmetrically and spaced apart. An operator manually or with a tool presses the first locking portion 131 towards the second locking portion 132. As the head 1312 gradually enters the blind hole of the second locking portion 132, the outer diameter of the head 1312 gradually decreases, facilitating the insertion of the head 1312 into the blind hole of the second locking portion 132, so that the locking member 13 achieves the effect of closing the opening 111. The two ends of the wing portions 1313 partially shield the blind hole. The wing portions 1313 can also be connected to the rear end of the head 1312, and the two ends of the wing portions 1313 can be clamped to assist the head 1312 in entering the blind hole.

[0076] In another embodiment, the first locking portion 131 includes a head 1312 and an elastic portion 1314 connected to the rear end of the head 1312. An operator can clamp and squeeze the elastic portion 1314, thereby driving the outer diameter of the head 1312 to gradually decrease, facilitating the insertion of the head 1312 into the blind hole of the second locking portion 132 and achieving the effect of the locking member 13 closing the opening 111.

[0077] Optionally, the blind hole of the second locking portion 132 is provided in the limiting platform 117, and the central axis of the blind hole is perpendicular to the central axis of the through hole 110. In this way, a part of the head 1312 of the first locking portion 131 is inserted into the blind hole, making the structure of the locking member 13 compact and reducing the occupied space.
