[0064] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0065] Embodiment 1

[0066] This embodiment relates to a pipeline joint structure, including a connector 2 inserted at the end of a pipeline 1. Among them, a clamping part and a limiting part are provided on the pipeline 1, and a clamping fitting part, a limiting fitting part and an ejection guiding part are provided on the connector 2.

[0067] Among them, when the connector 2 is inserted onto the pipeline 1, the clamping part and the clamping fitting part are clamped together along the insertion direction of the connector 2, and the limiting part and the limiting fitting part form a limiting fit to limit the relative rotation between the connector 2 and the pipeline 1.

[0068] In addition, when the limiting fit between the limiting portion and the limiting fitting portion is broken, the connector 2 can rotate relative to the pipeline 1 and release the engagement between the snap-fit portion and the snap-fitting portion, and the connector 2 after the snap-fit is released can be detached from the pipeline 1 under the guidance of the disengagement guide portion.

[0069] The pipe joint structure of this embodiment can clamp the connecting member 2 and the pipe 1 together by arranging a clamping portion and a limiting portion on the pipe 1, and arranging a clamping fitting portion, a limiting fitting portion and a disengagement guide portion on the connecting member 2. At the same time, the relative rotation between the connecting member 2 and the pipe 1 can also be limited, thereby improving the connection reliability between the two.

[0070] At the same time, when the limiting fit between the limiting portion and the limiting fit portion is broken, the connector 2 can rotate relative to the pipeline 1, and the escape guide portion can guide the connector 2 to facilitate the connector 2 to be separated from the pipeline 1. Therefore, the pipeline joint structure provides a new type of joint structure, and can ensure the connection reliability between the connector 2 and the pipeline 1.

[0071] Based on the above design concept, an exemplary structure of the pipe joint structure of this embodiment is referred to as Figure 1 and Figure 2 As shown in FIG. 1 , the pipeline 1 and the connector 2 are plug-connected along the axial direction of the connecting end of the pipeline 1. Figure 3 and Figure 4 As shown in the figure, as a specific embodiment, the end of the pipe 1 in this embodiment connected to the connector 2 is in an "L" shape to reduce the space occupied by the pipe 1 in the height direction, which is convenient for its arrangement in the component. Of course, when the pipe 1 is used to connect with other parts, its specific shape is not limited to Figure 4 As shown in FIG. 1 , for example, the pipeline 1 may be linear as a whole.

[0072] In addition, combined Figure 3 and Figure 4 As shown in , the clamping part of this embodiment includes a clamping joint 101 provided at the end of the pipeline 1, and the clamping joints 101 are arranged in a plurality of intervals along the circumference of the pipeline 1. Figures 3 to 6 As shown in the figure, the clamping joint 101 protrudes from the inside of the pipeline 1, and the end thereof connected to the pipeline 1 is configured as a plane, and abuts against the clamping boss 2011 described below through the plane. This design can improve the clamping firmness between the pipeline 1 and the connector 2. At this time, in order to facilitate the clamping connection between the connector 2 and the pipeline 1, still refer to Figure 3 and Figure 4 As shown in FIG, the side of the clamping joint 101 facing the inside of the pipeline 1 is arranged as an inclined surface, and because a plurality of clamping joints 101 are arranged at intervals along the circumference of the pipeline 1, each clamping joint 101 is arranged on the pipeline 1 in a cantilever shape.

[0073] Thus, when the connecting member 2 is inserted into the interior of the pipeline 1, the inclined surface on the clamping joint 101 can guide the connecting member 2 into the interior of the pipeline 1 and radially push the clamping joint 101 outwards along the pipeline 1. When the connecting member 2 is inserted in place, the clamping joint 101 can contract radially along the pipeline 1 and be clamped onto the corresponding clamping boss 2011 described below.

[0074] The structure of the connecting member 2 in this embodiment is referred to Figures 7 to 11 as shown in. Correspondingly, the connecting member 2 is integrally cylindrical, and it has a communication channel communicating with the interior of the pipeline 1. The pipeline 1 communicates with the connection port of the workpiece through this communication channel. Moreover, the above-mentioned clamping and mating portion includes clamping bosses 2011 provided on the outer peripheral wall of the connecting member 2. There are multiple clamping bosses 2011 provided in one-to-one correspondence with each clamping joint 101. When the connecting member 2 is inserted onto the pipeline 1, each clamping joint 101 is clamped onto the corresponding clamping boss 2011. Among them, for the convenience of arranging the clamping boss 2011, as Figure 7 shown in, at one end of the connecting member 2 connected to the pipeline 1, there is a convex ring 201 protruding radially outwards from itself. The clamping boss 2011 is provided at one end of the convex ring 201 away from the pipeline 1, and the clamping boss 2011 protrudes towards the end away from the pipeline 1.

[0075] In addition, it should be noted that the number of the clamping joints 101 and the clamping bosses 2011 is not specifically limited in this embodiment and can be adjusted accordingly according to the design requirements. In addition, in addition to arranging the clamping joints 101 on the pipeline 1 and arranging the clamping bosses 2011 on the connecting member 2 to achieve the clamping between the pipeline 1 and the connecting member 2. During specific implementation, according to the design requirements, the clamping joints 101 can also be arranged on the connecting member 2 and the clamping bosses 2011 can be arranged on the pipeline 1. This structure can also achieve the clamping between the pipeline 1 and the connecting member 2.

[0076] As a preferred implementation manner, in combination with Figure 1 、 Figure 3 and Figure 7 shown in, the limiting portion of this embodiment includes a limiting groove K provided at the end of the pipeline 1. The limiting groove K is formed between the limiting block 102 at the end of the pipeline 1 and one of the clamping joints 101. The limiting and mating portion includes a limiting and mating block 2012 provided on the outer peripheral wall of the connecting member 2. And when the connecting member 2 is inserted onto the pipeline 1, the limiting and mating block 2012 is inserted into the limiting groove K to form the limiting and mating between the limiting portion and the limiting and mating portion. And when the limiting and mating block 2012 falls off from the connecting member 2, the limiting and mating between the limiting portion and the limiting and mating portion is destroyed.

[0077] Among them, as Figure 4As shown, the limiting block 102 of this embodiment is arranged adjacent to one of its clamping joints 101, and the limiting groove K is formed between the limiting block 102 and the adjacent other clamping joint 101. And, as a preferred embodiment, for the convenience of processing and manufacturing, the length of the limiting block 102 in the axial direction of the pipeline 1 is the same as the length of the clamping joint 101. In this embodiment, the limiting part includes the limiting groove K provided at the end of the pipeline 1, and the limiting groove K is formed between the limiting block 102 at the end of the pipeline 1 and one of its clamping joints 101, which is convenient for arranging the limiting groove K. The limiting and matching part includes the limiting and matching block 2012 provided on the outer peripheral wall of the connecting piece 2, and the structure is conventional, which is convenient for design and implementation.

[0078] And in combination Figure 7 with Figure 9 as shown, for the convenience of arranging the limiting and matching block 2012, a convex block is provided on the convex ring 201 of the connecting piece 2, and the convex block protrudes axially from the convex ring 201 towards the end away from the pipeline 1. The limiting and matching block 2012 of this embodiment is arranged on the convex block and protrudes radially outwards along the convex ring 201. Designed in this way, when the connecting piece 2 is inserted into the pipeline 1 along the insertion direction, the clamping joint 101 can be clamped on the clamping boss 2011. At the same time, the limiting and matching block 2012 can also be snapped into the limiting groove K, so as to form a limiting and matching between the connecting piece 2 and the pipeline 1, which can limit the rotation of the connecting piece 2 relative to the pipeline 1, and thus improve the connection reliability between the pipeline 1 and the connecting piece 2.

[0079] It can be understood that the number of the limiting grooves K and the limiting and matching blocks 2012 is not limited to the group shown in the figure. To further improve the limiting effect, the limiting grooves K and the limiting and matching blocks 2012 can also be set as multiple groups in one-to-one correspondence. However, at this time, when disassembling the pipeline 1, multiple limiting and matching blocks 2012 need to be damaged, which will obviously reduce the disassembly efficiency of the pipeline 1, and at the same time, there will be more requirements for the processing accuracy and processing cost.

[0080] In addition, in order to improve the connection efficiency between the pipeline 1 and the connecting piece 2, as a further implementation manner, a guiding part is provided between the limiting groove K and the limiting and matching block 2012, and the guiding part is used to guide the limiting and matching block 2012 to be snapped into the limiting groove K. Among them, in combination Figure 4 with Figure 7 as shown, the guiding part of this embodiment includes a guiding inclined surface 1021 provided on one side of the limiting groove K, and a matching inclined surface 20121 provided on one side of the limiting block 102 and adapted to the guiding inclined surface 1021.

[0081] The setting of the guiding slope 1021 makes the width of the limit groove K gradually increase in the direction away from the pipeline 1, so as to facilitate the fast insertion of the limit matching block 2012 into the limit groove K. In addition, the matching slope 20121 is adapted to the guiding slope 1021, which means that the inclination angles between the two are the same, and they can abut against each other during the plugging process of the connector 2 and the pipeline 1. In this embodiment, as a preferred embodiment, Figure 4 As shown in , the guide slope 1021 is provided on the limit block 102. Of course, in addition to providing the guide slope 1021 on the limit block 102, it is also feasible to provide the guide slope 1021 on the clamping boss 2011 opposite to the limit block 102, but in this case, the clamping effect between the clamping boss 2011 and the clamping joint 101 may be reduced.

[0082] In this embodiment, by providing a guide portion between the limit groove K and the limit matching block 2012, it is convenient to guide the limit matching block 2012 to snap into the limit groove K, which is conducive to realizing a quick connection between the connector 2 and the pipeline 1, and can improve the connection efficiency. The guide portion adopts the form of a guide slope 1021 and a matching slope 20121 adapted thereto, which has a simple structure and is easy to manufacture.

[0083] In addition, as a preferred embodiment, Figure 7 As shown in , the disengagement guide portion of this embodiment includes a disengagement slope 2013 provided on the connector 2, and a disengagement slope 2013 is provided on the same side of each clamping boss 2011. The disengagement slope 2013 is provided at one end of the convex ring 201 away from the pipeline 1, and extends between two adjacent clamping bosses 2011 along the circumferential direction of the convex ring 201. Therefore, when the limiting matching block 2012 is damaged and falls off from the connector 2, the connector 2 can be easily disengaged from the pipeline 1 through the guidance of the disengagement slope 2013.

[0084] Here, it should be noted that, since the limiting structure can limit the rotation of the pipeline 1 relative to the connector 2, in the natural state, the clamping joint 101 and the escape slope 2013 are staggered, which can effectively prevent the pipeline 1 from detaching from the connector 2.

[0085] In addition, as a further embodiment, a sealing structure is provided between the pipeline 1 and the connector 2, and when the connector 2 is plugged into the pipeline 1, the sealing structure forms a seal between the pipeline 1 and the connector 2. Among them, as a preferred embodiment, Figure 2 and Figure 10 As shown in the figure, the sealing structure of this embodiment includes a first sealing groove 2014 provided at one end of the connecting member 2, a first sealing ring 5 provided in the first sealing groove 2014, and a sealing rib 104 provided on the inner wall of the pipeline 1, and the sealing rib 104 is annular, and when the connecting member 2 is inserted into the pipeline 1, the sealing rib 104 abuts against the first sealing ring 5.

[0086] Specifically, combined with Figure 7 , Figure 9 and Figure 10 As shown, and based on Figure 10 As shown below, the first sealing groove 2014 is provided at the top of the convex ring 201 and is annularly arranged along the circumference of the convex ring 201. In addition, in order to further improve the sealing effect, as shown in FIG. Figure 10 As shown, the cross section of the first sealing groove 2014 is in an inverted "T" shape, and includes a groove body, and a mounting groove arranged at the bottom of the groove body, and the width of the mounting groove is greater than the width of the groove body.

[0087] Correspondingly, the structure of the first sealing ring 5 of this embodiment is as follows: Figure 11 As shown in the figure, it is arranged in the shape of the first sealing groove 2014, and includes a sealing ring body, and a bottom part 501 arranged at the bottom of the sealing ring body, and the bottom part 501 is arranged to protrude outward along the width direction of the sealing ring body. Moreover, in the assembled state, the bottom part 501 of the first sealing ring 5 is arranged in the installation groove, and the sealing ring body is located in the groove body. Therefore, the bottom part 501 can prevent the first sealing ring 5 from slipping out of the first sealing groove 2014, and the sealing ring body is used to abut against the sealing rib 104 to achieve sealing between the pipeline 1 and the connecting piece 2.

[0088] In addition, in this embodiment, in order to improve the sealing effect between the pipeline 1 and the connector 2, at least two sealing protrusions 502 are arranged at intervals along the width direction of the sealing ring body. In addition, each sealing protrusion 502 is used to abut against the sealing rib 104 to form a multi-pass seal, and a deformation space for the sealing ring body to deform is formed between two adjacent sealing protrusions 502. Among them, as a specific embodiment, Figure 11 As shown in FIG. 1 , the sealing protrusions 502 of this embodiment are two spaced apart along the width direction of the sealing ring body. Figure 11 The two interval settings can also be designed to have other numbers of interval settings according to design requirements.

[0089] In order to facilitate the setting of the sealing rib 104, Figure 6 As shown, a sealing plate 103 protrudes radially inwardly of the pipeline 1 on the inner wall of the pipeline 1, and a sealing rib 104 is specifically provided on the sealing plate 103 and protrudes toward one end close to the pipe opening. Moreover, the sealing rib 104 is annular and is provided in accordance with the first sealing ring 5.

[0090] Here, it should be noted that, in addition to providing the first sealing groove 2014 and the first sealing ring 5 on the connector 2, the sealing rib 104 is also provided on the pipeline 1. The sealing rib 104 can also be provided on the connector 2, and the first sealing groove 2014 and the first sealing ring 5 are provided on the pipeline 1. This structure can also achieve sealing between the pipeline 1 and the connector 2. Figure 11 The structure shown can also use a commonly used sealing ring with a circular cross section. However, in this case, the first sealing ring 5 needs to be fixed to the connector 2 by bonding or other means to prevent the first sealing ring 5 from detaching from the connector 2, thereby causing the sealing between the pipeline 1 and the connector 2 to fail.

[0091] The pipe joint structure of this embodiment, by adopting the above structure, can clamp the pipe 1 and the connector 2 together, and at the same time, can limit the relative rotation between the connector 2 and the pipe 1, which can improve the connection reliability between the two. In addition, when the limiting fit between the limiting portion and the limiting fit portion is broken, the connector 2 can rotate relative to the pipe 1, and the escape guide portion can guide the connector 2, so that the connector 2 can be separated from the pipe 1. Therefore, this pipe joint structure provides a new type of joint structure, and can ensure the connection reliability between the connector 2 and the pipe 1.

[0092] Embodiment 2

[0093] This embodiment relates to a pipeline connection structure for connecting a pipeline 1 to a connection port on a workpiece. The pipeline connection structure includes a pipeline joint structure as described in Embodiment 1 connected to the pipeline 1, and one end of a connector 2 is connected to the connection port on the workpiece.

[0094] In order to facilitate understanding of this embodiment, Figures 12 to 14 As shown in , this embodiment is specifically described by taking the liquid cooling plate 4 of the battery pack as an example, and because the size of the liquid cooling plate 4 is generally large, in order to clearly illustrate the improvement points of this embodiment, Figure 12 Only the partial structure of the liquid cooling plate 4 is shown. It can be understood that the parts are Figure 12 The liquid cooling plate 4 shown in the figure can of course also be other components according to design requirements. That is to say, the pipeline 1 plug-in structure of this embodiment can be used not only between the liquid cooling plate 4 and the pipeline 1, but also between other components and the pipeline 1 to achieve connection between them.

[0095] In a specific implementation, the connector 2 can be connected to the connection port on the workpiece by, for example, screw connection or clamping. And, as a preferred embodiment, taking one end of the connector 2 being clamped to the connection port as an example, in order to facilitate the clamping of the connector 2 to the connection port, Figure 15 and Figure 16As shown in the figure, in this embodiment, a base 3 communicating with the inside thereof may be provided on the liquid cooling plate 4, the connection port is provided on the base 3, and the connecting member 2 is specifically clamped on the base 3.

[0096] Moreover, as a preferred embodiment, in combination with Figures 17 to 19 As shown in the figure, the base 3 of this embodiment includes an annular base body 301 and a mounting plate 302 protruding radially outward along the base body 301. And, the inner diameter of the base body 301 is adapted to the connecting member 2, the mounting plate 302 is an annular shape surrounding the base body 301, and is composed of Figure 16 As shown in the figure, one end of the base body 301 of this embodiment is inserted into the liquid cooling plate 4, and the mounting plate 302 abuts against the liquid cooling plate 4. At this time, to improve the sealing effect between the base 3 and the liquid cooling plate 4, in specific implementation, the base 3 and the housing of the liquid cooling plate 4 can be made of a metal material such as aluminum alloy, and preferably the mounting plate 302 is welded to the liquid cooling plate 4.

[0097] Here, it should be noted that in addition to welding the mounting plate 302 to the liquid cooling plate 4, a groove surrounding the connection port can also be provided on the liquid cooling plate 4, and a plurality of studs are arranged at intervals around the groove. At this time, correspondingly, a plurality of mounting holes corresponding to the studs can be provided on the mounting plate 302, and a sealing gasket abutting against the mounting plate 302 can be provided in the groove, and then it is also feasible to install the mounting plate 302 on the liquid cooling plate 4 through bolts.

[0098] As a preferred implementation manner, one end of the connecting member 2 is provided with clamping teeth 202, and the clamping teeth 202 are a plurality of circumferentially spaced arrangements along the connecting member 2, and when the connecting member 2 is inserted into the base 3, each clamping tooth 202 is clamped on the base 3. Among them, the clamping teeth 202 can specifically be 2 - 8 circumferentially spaced along the connecting member 2. In combination with Figure 7 and Figure 14 As shown in the figure, relative to the end connected to the pipeline 1 by insertion, the clamping teeth 202 of this embodiment are provided at the other end of the connecting member 2. And, as a specific embodiment, as Figure 7 As shown in the figure, each clamping tooth 202 is an arc-shaped circumferentially arranged along the connecting member 2, and the inner side surface of the clamping tooth 202 is flush with the inner wall of the connecting member 2, while the outer side of the clamping tooth 202 protrudes relative to the connecting member 2 to be able to be clamped on the base 3.

[0099] In addition, to improve the clamping firmness, based on Figure 10 the state shown in the figure, the side of the clamping tooth 202 in contact with the base 3 is a plane. And because the outer side of the clamping tooth 202 protrudes relative to the connecting member 2, at this time, to facilitate the clamping tooth 202 to pass through the base body 301 to be clamped and connected to the base body 301, as Figure 7 and Figure 10As shown in the figure, a guiding surface is provided on the outer side of the engaging teeth 202, and specifically, the guiding surface is a smoothly transitioning arc surface. Thus, when the connecting member 2 is engaged with the base 3, under the guidance of the guiding surface, each engaging tooth 202 can be driven to contract radially inward along the base body 301, facilitating the engagement of each engaging tooth with one end of the base body 301 after passing through the base body 301.

[0100] It should be noted that in addition to engaging the connecting member 2 with the base 3, screwing the two together is also feasible. Additionally, in addition to being set as the Figure 7 arc surface shown in the figure, the guiding surface can also be set as an inclined surface that forms an angle with the axial direction of the connecting member 2, as long as it can guide the engaging teeth 202 to engage with the base 3.

[0101] Furthermore, as a further implementation manner, a sealing portion is provided between the connecting member 2 and the connection port to ensure the sealing effect between the connecting member 2 and the component. As a preferred implementation manner, the sealing portion of this embodiment includes a second sealing groove 2015 provided on the connecting member 2 and a second sealing ring 6 provided in the second sealing groove 2015. When the connecting member 2 is inserted into the base 3, one end of the base 3 abuts against the second sealing ring 6. Among them, as Figure 12 and Figure 16 shown in the figure, based on the above structures of the connecting member 2 and the base 3, the second sealing groove 2015 of this embodiment is specifically provided on the convex ring 201 of the connecting member 2 and is located at the other end of the convex ring 201 relative to the above-mentioned first sealing ring 5.

[0102] Moreover, in order to improve the sealing effect, the second sealing groove 2015 of this embodiment is in a "T" shape, and its structure is the same as that of the above-mentioned first sealing groove 2014. Thus, the structures of the first sealing ring 5 and the second sealing ring 6 are the same, which can reduce the development and manufacturing costs. Therefore, the structure of the second sealing ring 6 will not be elaborated here. Also, the second sealing ring 6 adopting the same structure as the above-mentioned first sealing ring 5 can not only prevent the second sealing ring 6 from coming out of the second sealing groove 2015 but also improve the sealing effect between the connecting member 2 and the base 3. Additionally, to facilitate the insertion of the base body 301 into the second sealing groove 2015, as Figure 17 and Figure 19 shown in the figure, one end of the base body 301 is provided with a chamfer.

[0103] It should be noted here that in addition to adopting the same structure as the first sealing ring 5, the second sealing ring 6 can also adopt a commonly used existing sealing ring with a circular cross-section. However, in this case, methods such as bonding are required to fix the second sealing ring 6 on the connecting member 2 to prevent the second sealing ring 6 from detaching from the connecting member 2, resulting in sealing failure between the base 3 and the connecting member 2.

[0104] In addition, the provision of the engaging teeth 202 on the connecting member 2, and the provision of the second sealing groove 2015 and the second sealing ring 6 on the connecting member 2 is only a preferred embodiment. In specific implementation, it is also feasible to provide threads on the connecting member 2 instead of providing the engaging teeth 202, so as to screw the connecting member 2 to the base 3. Alternatively, the second sealing groove 2015 and the second sealing ring 6 are provided on the base 3 instead of providing the connecting member 2, and the connecting member 2 is inserted into the second sealing groove 2015 on the base 3, so as to achieve sealing between the connecting member 2 and the base 3.

[0105] In this embodiment, when connecting the connecting member 2 to the base 3, first, Figure 16 The connector 2 is moved downward from top to bottom, and then, under the action of the guiding surfaces of the engaging teeth 202, the engaging teeth 202 are driven to deform radially inwardly along the base 3. When the connector 2 reaches the assembly position, the upper end of the engaging teeth 202 cooperates with the lower end of the base body 301, and the upper end of the base body 301 abuts against the second sealing ring 6, thereby limiting the connector 2 in the up and down and left and right directions. At this time, the second sealing ring 6 is compressed by the upper end of the base body 301, so that a stable sealing form is formed between the connector 2 and the base 3. At the same time, because the base body 301 is welded to the liquid cooling plate 4, the sealing performance between the two can also be met.

[0106] When connecting the pipe 1 to the connector 2, first, Figure 2 The pipeline 1 is moved from top to bottom in the middle, and then, under the guidance of the inner inclined surface of each clamping joint 101, the clamping joint 101 is driven to expand radially outwardly along the pipeline 1 to plug the pipeline 1 into the connector 2. Then, when the pipeline 1 reaches the assembly position, the upper end of the clamping joint 101 is clamped on the corresponding clamping boss 2011, and the sealing rib 104 abuts on the first sealing ring 5 to achieve axial limitation of the pipeline 1. At the same time, the limiting matching block 2012 on the connector 2 is inserted into the limiting groove K under the guidance of the matching inclined surface 20121, thereby limiting the rotation of the pipeline 1. At the same time, the sealing rib 104 presses the first sealing ring 5 to form a seal between the pipeline 1 and the connector 2.

[0107] When the pipeline 1 needs to be disassembled or replaced, the limiting matching block 2012 on the connector 2 needs to be destroyed with a tool so that the pipeline 1 loses its rotation limit. Figure 1 When the clamping joint 101 is disengaged from the clamping boss 2011 and corresponds to the disengagement slope 2013, the clamping joint 101 is rotated in the direction shown in FIG. Figure 1 Just unplug the pipe 1 from the connector 2 from bottom to top.

[0108] When it is necessary to connect to the pipeline 1 again, the engaging teeth 202 on the connector 2 can be pushed inwards with a tool so that each engaging tooth 202 is disengaged from the engaging connection with the base 3, and the connector 2 can be removed from the base 3. After the connector 2 is replaced, it can be plugged and connected to the pipeline 1. In addition, in order to facilitate the preparation and use of the connector 2, the connector 2 can generally be made of thermoplastic composite materials, such as PP (Polypropylene), PA6 (Polyamide 6, nylon-6), PA66 (Polyamide 66, nylon-66), PPO (Polyphenylene Oxide, polyphenylene ether) or ABS (AcrylonitrileButadieneSyrene, acrylonitrile-styrene-butadiene copolymer).

[0109] The pipeline connection structure of this embodiment adopts the above structure, which has a simple structure and is easy to prepare and use. At the same time, it also helps to reduce the occupied space, is easy to arrange, and is easy to assemble and disassemble, and has good practicality.
