Description

Technical Field

[0001] This utility model relates to the field of building partition devices, and more particularly to a sliding and expandable barrier for adjustable installation between two relatively fixed positions (such as walls, columns, and door frames) to achieve spatial separation and fixation. Background Technology

[0002] In existing technologies, barrier devices used to separate two relative positions often suffer from problems such as inconvenient adjustment and insufficient stability. Traditional barrier structures are mostly fixed in size or only have simple sliding functions, making it difficult to flexibly expand and precisely fix them according to the spatial dimensions of the actual use scenario. For example, when barriers need to be installed in passages or spaces of different widths, traditional devices often require complex installation steps or additional auxiliary components, resulting in low efficiency. In addition, the locking and pressurizing structures of existing barriers are usually relatively simple, making them prone to loosening during use, affecting the stability and safety of the barrier. Therefore, there is an urgent need for a barrier device that can flexibly slide and expand in the length direction and achieve stable fixation through reliable locking and pressurizing components.

[0003] Furthermore, various barrier devices currently available on the market all employ four-point support, requiring users to find four support points between two relative positions to secure the barrier device. The slidable extendable barrier of this invention only requires three support points between two relative positions to be fixed in place.

[0004] Therefore, this invention provides a slidable and expandable barrier that can effectively solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a sliding and expandable barrier with a simple structure. It can slide and expand flexibly in the length direction and achieve a stable fixation through reliable locking and pressurizing components. At the same time, it only needs to find three support points between two relative positions to fix it in the required position, further improving the user experience.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A slidable, expandable barrier for placement between two opposing positions, comprising:

[0008] A first sliding partition includes a first frame, the first sliding partition extending along the length and height directions;

[0009] The second sliding partition includes a second frame, the second sliding partition extends along the length and height directions, and the first sliding partition and the second sliding partition are capable of sliding relative to each other in the length direction;

[0010] A locking component for optionally locking the first sliding partition and the second sliding partition in the length direction;

[0011] When the locking component locks the first sliding partition and the second sliding partition in the length direction, the adjusting pressure component applies pressure to the first sliding partition and the second sliding partition, thereby gradually applying pressure to the two relative positions, so that the slidable expandable barrier is fixed between the two relative positions.

[0012] As an improvement to this utility model, it also includes a fixed pressure end member. The first frame includes a first outer end member and a first inner end member, and the second frame includes a second outer end member and a second inner end member. The adjusting pressure assembly includes a mounting base and a slidable pressure end member. The mounting base is fixedly connected to the first outer end member, and the fixed pressure end member is fixedly connected to the second outer end member. When the locking assembly locks the first sliding partition and the second sliding partition at a suitable position in the length direction, the adjusting pressure assembly applies pressure to the first sliding partition and the second sliding partition, thereby gradually causing the slidable pressure end member and the fixed pressure end member to apply pressure to the two relative positions, so that the slidably expandable barrier is fixed between the two relative positions. The fixed pressure end member includes a mounting surface and an abutting surface. The mounting surface contacts the surface of the second outer end member, and the abutting surface abuts against one of the two relative positions.

[0013] As an improvement of this utility model, the adjusting pressure assembly further includes an adjusting handle, and the mounting base further includes an adjusting screw. The adjusting handle has a first internal thread, and the adjusting screw has a first external thread that matches the first internal thread. The adjusting handle and the adjusting screw are connected by threads. The adjusting screw includes an adjusting through hole, and the slidable pressure end piece includes a screw portion and an abutting end. The screw portion has a second external thread, and the maximum outer diameter of the screw portion is smaller than the inner diameter of the adjusting through hole, so that the screw portion can slide in the adjusting through hole. The adjusting pressure assembly further includes a limiting nut. The maximum outer diameter of the limiting nut is larger than the inner diameter of the adjusting through hole, and the limiting nut has a second internal thread that matches the second external thread. After the screw portion of the slidable pressure end piece passes through the adjusting through hole, it is threadedly connected to the limiting nut, so that when the slidable pressure end piece slides in the adjusting through hole, the screw portion is always partially located in the adjusting through hole.

[0014] As an improvement of this utility model, the adjusting pressure assembly further includes an auxiliary adjusting nut, which has a third internal thread that matches the second external thread. The screw portion of the slidable pressure end member first passes through the auxiliary adjusting nut, then through the adjusting through hole, and finally is threadedly connected to the limiting nut. The first outer end member has a receiving through hole, the position of which matches the position of the adjusting through hole, and the inner diameter of the receiving through hole is larger than the maximum outer diameter of the limiting nut, so that the end of the screw portion connected to the limiting nut can slide in the receiving through hole.

[0015] As an improvement to this utility model, it also includes an elongated member, which is fixedly connected to the first frame or the second frame, and the elongated member has a plurality of spaced-apart preset positions. The locking component can selectively lock the first sliding partition and the second sliding partition at each of the preset positions. The locking component includes a locking rod, which includes a locking end and a control end. The preset position is provided with a locking hole. When the locking end and the locking hole are aligned, the control end is pressed to lock the first sliding partition and the second sliding partition, so that the first sliding partition and the second sliding partition cannot slide relative to each other in the length direction. The locking component also includes a control button, which is used to release the locking state of the first sliding partition and the second sliding partition, so that the first sliding partition and the second sliding partition can slide relative to each other in the length direction.

[0016] As an improvement of this utility model, the direction between the first frame and the second frame is the width direction, the first frame and the second frame mesh with each other and maintain a gap in the width direction, and the first frame and the second frame are parallel to each other and slide parallel to each other along the length direction.

[0017] As an improvement to this utility model, a sliding guide assembly is also included. The sliding guide assembly is fixedly installed on the first frame and the second frame to keep the first frame and the second frame stable during sliding. The sliding guide assembly includes multiple guide elements, each guide element including a fixed mounting part and a sliding mounting part. The first frame includes a first upper component and a first lower component, and the second frame includes a second upper component and a second lower component. The multiple fixed mounting parts corresponding to the multiple guide elements are respectively fixedly connected to the first upper component, the first lower component, the second upper component, and the second lower component. The multiple sliding mounting parts corresponding to the multiple guide elements are respectively slidably connected to the first upper component, the first lower component, the second upper component, and the second lower component. The first upper component, the first lower component, the second upper component, and the second lower component are at least simultaneously fixedly connected to at least one of the fixed mounting parts and slidably connected to at least one of the sliding mounting parts.

[0018] As an improvement of this utility model, the contact surface is provided with an anti-slip structure; the fixed pressure end member includes a first pressure end member and a second pressure end member, and the first pressure end member and the second pressure end member are distributed along the height direction of the second outer end member.

[0019] As an improvement to this utility model, a soft rubber partition is provided on the abutting end.

[0020] As an improvement of this utility model, the first sliding partition further includes a first isolation member, which is fixedly connected to the inside of the first frame. The second sliding partition further includes a second isolation member, which is fixedly connected to the inside of the second frame. The first isolation member is used to reduce the obstruction gap in the first sliding partition, and the second isolation member is used to reduce the obstruction gap in the second sliding partition. The first isolation member is a rod-shaped element or a mesh element uniformly arranged in the first frame, and the second isolation member is a rod-shaped element or a mesh element uniformly arranged in the second frame.

[0021] The beneficial effects of this utility model are: through the above-mentioned structure, when in use, the logic of "sliding adjustment - locking positioning - pressurizing fixation" is used to achieve the core advantages of "flexible adaptation, quick installation, and stable reliability". It is especially suitable for application scenarios with high requirements for installation convenience, environmental friendliness (no damage) and scene adaptability, and has both functionality and practicality.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] Reference Figures 1 to 10 A slidable, expandable barrier for placement between two opposing positions, comprising:

[0043] The first sliding partition 100 includes a first frame 110, and the first sliding partition 100 extends along the length and height directions;

[0044] The second sliding partition 200 includes a second frame 210. The second sliding partition 200 extends along the length and height directions, and the first sliding partition 100 and the second sliding partition 200 are capable of sliding relative to each other in the length direction.

[0045] Locking component 300, the locking component 300 being used to selectively lock the first sliding partition 100 and the second sliding partition 200 in the length direction;

[0046] When the locking component 300 locks the first sliding partition 100 and the second sliding partition 200 in the length direction, the adjusting pressure component 400 applies pressure to the first sliding partition 100 and the second sliding partition 200, thereby gradually applying pressure to the two relative positions, so that the slidable expandable barrier is fixed between the two relative positions.

[0047] With the above-described structure, in use, the first sliding partition 100 serves as the basic structural unit of the barrier, extending along its length and height to form the main frame of the barrier, providing physical support and initial blocking function. The second sliding partition 200 cooperates with the first sliding partition 100, changing the total length of the barrier through relative sliding to cover spatial gaps of different widths, thus improving the barrier's applicability. The locking component 300 fixes the relative positions of the first sliding partition 100 and the second sliding partition 200 after they have slid to the target length, preventing the partitions from sliding due to external forces (such as collisions, wind pressure, etc.) during use, ensuring the barrier's stability. The locking component 300 acts as a key switching component between "sliding adjustment" and "fixed pressure bearing." Only in the locked state can the adjusting pressure component 400 effectively apply pressure to the barrier, achieving the fixation of the barrier between the two relative positions. Through the synergistic effect of each structure, this slidable extendable barrier achieves a complete functional chain of "flexible adjustment—reliable locking—stable fixation," enhancing the user experience. The length direction described in this application is the direction indicated by axis a, the width direction is the direction indicated by axis b, and the height direction is the direction indicated by axis h.

[0048] In this embodiment, a fixed pressure-applying end member 500 is also included. The first frame 110 includes a first outer end member 111 and a first inner end member 112. The second frame 210 includes a second outer end member 211 and a second inner end member 212. The adjusting pressure-applying assembly 400 includes a mounting base 410 and a slidable pressure-applying end member 420. The mounting base 410 is fixedly connected to the first outer end member 111, and the fixed pressure-applying end member 500 is fixedly connected to the second outer end member 211. When the locking assembly 300 locks the first sliding partition 100 and the second sliding partition 200 at a suitable position in the length direction, the adjusting pressure-applying assembly 400 applies pressure to the first sliding partition 100 and the second sliding partition 200, thereby gradually causing the slidable pressure-applying end member 420 and the fixed pressure-applying end member 500 to apply pressure to the two relative positions, so that the slidably expandable barrier is fixed between the two relative positions. With the above-described structure, during use, the first sliding partition 100 and the second sliding partition 200 adjust the barrier length by sliding relative to each other to adapt to different spacing requirements; the first frame 110 and the second frame 210 provide support and stability. The locking component 300 fixes the partition position to ensure that it does not slide during use. The adjusting pressure component 400 includes the mounting base 410 and the slidable pressure end piece 420. The former is fixed to the first outer end member 111 to transmit power, and the latter dynamically outputs pressure; the fixed pressure end piece 500 is connected to the second outer end member 211 to transmit pressure on the fixed side. The components work together to achieve "sliding adjustment - locking and shaping - double-end pressure fixing", which has advantages such as flexibility, stability and convenience, and is suitable for scenarios such as home protection.

[0049] In this embodiment, the fixed pressure end member 500 includes a mounting surface 510 and an abutment surface 520. The mounting surface 510 is in surface contact with the second outer end member 211, and the abutment surface 520 abuts against one of the two relative positions. With this structural arrangement, during use, the surface contact between the mounting surface 510 and the second outer end member 211 allows for more uniform transmission of structural force, avoiding stress concentration, ensuring installation positioning accuracy and structural compatibility, and enhancing connection strength. The abutment surface 520 abutting against one of the two relative positions allows for more uniform pressure distribution and increased contact area to improve friction.

[0050] In this embodiment, the adjusting pressurization component 400 further includes an adjusting handle 430, and the mounting base 410 further includes an adjusting screw 411. The adjusting handle 430 has a first internal thread 431, and the adjusting screw 411 has a first external thread 4111 that matches the first internal thread 431. The adjusting handle 430 and the adjusting screw 411 are connected by threads. With the above structure, in use, the first internal thread 431 in the adjusting handle 430 is threadedly connected to the first external thread 4111 in the adjusting screw 411, forming a helical transmission mechanism. The adjusting handle 430 serves as a manual drive interface, converting manual power into the axial movement of the screw through rotation. Its threaded self-locking characteristic prevents loosening after pressurization, and the pitch design controls the adjustment accuracy. Threaded connections offer advantages such as strong self-locking, stepless adjustment, and convenient maintenance, making them suitable for home and industrial applications. Compared to hydraulic and spring-based adjustment methods, they achieve a balance between ease of operation and reliability.

[0051] In this embodiment, the adjusting screw 411 includes an adjusting through hole 4112, and the slidable pressure-applying end piece 420 includes a screw portion 421 and an abutment end 422. The screw portion 421 is provided with a second external thread 4211, and the maximum outer diameter of the screw portion 421 is smaller than the inner diameter of the adjusting through hole 4112, so that the screw portion 421 can slide in the adjusting through hole 4112. With the above structure, in use, the adjusting through hole 4112 provides axial sliding space for the screw portion 421. The inner diameter of the adjusting through hole 4112 is larger than the maximum outer diameter of the screw portion 421. The constraint of the hole wall of the adjusting through hole 4112 ensures that the screw portion 421 moves smoothly along the axis, accurately transmitting thrust. The adjusting through hole 4112 limits and prevents the screw portion 421 from deviating, achieving efficient and stable pressure transmission with a simple structure.

[0052] In this embodiment, the adjusting pressure assembly 400 further includes a limiting nut 440. The maximum outer diameter of the limiting nut 440 is greater than the inner diameter of the adjusting through hole 4112, and the limiting nut 440 is provided with a second internal thread 441. The second internal thread 441 matches the second external thread 4211. After the screw portion 421 of the slidable pressure end member 420 passes through the adjusting through hole 4112, it is threadedly connected to the limiting nut 440, so that when the slidable pressure end member 420 slides in the adjusting through hole 4112, the screw portion 421 is always partially located in the adjusting through hole 4112. With the above-described structure, in use, the outer diameter of the limiting nut 440 is larger than the inner diameter of the adjusting through hole 4112, which can prevent the slidable pressure end piece 420 from completely dislodging from the adjusting through hole 4112, ensuring structural safety; the second internal thread 441 matches the second external thread 4211 of the screw part 421, and after connection, a stable constraint is formed, so that the screw part 421 always maintains a partially inserted state when sliding in the adjusting through hole 4112, avoiding the situation of dislodging from the adjusting through hole 4112.

[0053] In this embodiment, the adjusting pressure assembly 400 further includes an auxiliary adjusting nut 450. The auxiliary adjusting nut 450 has a third internal thread 451, which matches the second external thread 4211. The screw portion 421 of the slidable pressure end piece 420 first passes through the auxiliary adjusting nut 450, then through the adjusting through hole 4112, and finally is threadedly connected to the limiting nut 440. With the above structure, in use, the third internal thread 451 of the auxiliary adjusting nut 450 cooperates with the second external thread 4211 to form an additional guide fulcrum, which, together with the adjusting through hole 4112, restricts the radial displacement of the screw portion 421, reducing wobbling during sliding and improving the straightness of the pressure trajectory. The outer diameter of the limiting nut 440 is larger than the inner diameter of the adjusting through hole 4112, directly physically preventing the screw portion 421 from completely disengaging. The auxiliary adjusting nut 450 further restricts the maximum displacement of the screw portion 421 through a threaded connection.

[0054] In this embodiment, the first outer end member 111 is provided with a receiving through hole 1111. The position of the receiving through hole 1111 matches the position of the adjusting through hole 4112, and the inner diameter of the receiving through hole 1111 is larger than the maximum outer diameter of the limiting nut 440, so that the end of the screw part 421 connected to the limiting nut 440 can slide in the receiving through hole 1111. With the above structure, in use, the receiving through hole 1111 and the adjusting through hole 4112 cooperate to form a double guiding and limiting structure for the slidable pressure end member 420. The inner diameter of the receiving through hole 1111 is larger than the outer diameter of the limiting nut 440, allowing the end of the screw part 421 connected to the limiting nut 440 to slide freely in the hole, ensuring that the slidable pressure end member 420 moves smoothly in a straight line during pressurization, avoiding jamming or stress concentration caused by radial offset. Meanwhile, the receiving through hole 1111 provides movement space for the limiting nut 440, preventing the limiting nut 440 from interfering with the first outer end component 111, ensuring the efficient operation of the entire pressurization system, and enhancing the reliability and stability of the barrier fixation.

[0055] In this embodiment, an elongated member 600 is also included. The elongated member 600 is fixedly connected to the first frame 110 or the second frame 210, and has multiple spaced-apart preset positions 610. The locking component 300 can selectively lock the first sliding partition 100 and the second sliding partition 200 at each preset position 610. With this structure, in use, the preset positions 610 on the elongated member 600, which is fixed to the first frame 110 or the second frame 210, form discrete adjustment nodes, clearly indicating the lockable length value of the barrier. The user can quickly locate the desired position according to the actual spacing. The elongated member 600 is made of a high-strength material (such as steel), and after being rigidly connected to the frame, it can enhance the overall rigidity of the barrier and reduce deformation during sliding.

[0056] In this embodiment, the locking assembly 300 includes a locking rod 310, which includes a locking end 311 and a control end 312. A locking hole 611 is provided at the preset position 610. When the locking end 311 and the locking hole 611 are aligned and overlapped, pressing the control end 312 locks the first sliding partition 100 and the second sliding partition 200, preventing them from sliding relative to each other in the length direction. With this structure, in use, the locking rod 310 cooperates with the locking hole 611 to lock the first sliding partition 100 and the second sliding partition 200. The locking rod 310 is divided into the locking end 311 and the control end 312. The locking end 311 is shaped to match the locking hole 611, and the control end 312 is easy to press. When the first sliding partition 100 and the second sliding partition 200 slide to the target position, the locking end 311 coincides with the locking hole 611. Pressing the control end 312 allows the locking end 311 to be inserted into the locking hole 611 to lock the first sliding partition 100 and the second sliding partition 200. The locking rod 310 automatically rebounds via an elastic element.

[0057] In this embodiment, the locking component 300 further includes a control button 320, which is used to release the locking state of the first sliding partition 100 and the second sliding partition 200, allowing the first sliding partition 100 and the second sliding partition 200 to slide relative to each other in the length direction. Through the above structural design, the addition of the control button 320 further optimizes the operation flow and user experience of the locking component 300 during use. The control button 320 can drive the locking rod 310 to move with a simple press, causing the locking end 311 to disengage from the locking hole 611, quickly releasing the locking state of the first sliding partition 100 and the second sliding partition 200, realizing free sliding adjustment of the partitions, and greatly improving operational convenience. The control button 320 achieves automatic rebound through an elastic element.

[0058] In this embodiment, the direction between the first frame 110 and the second frame 210 is the width direction. The first frame 110 and the second frame 210 mesh with each other and maintain a gap in the width direction, and the first frame 110 and the second frame 210 are parallel to each other and slide parallel to each other in the length direction. With the above structure, in use, the design of the first frame 110 and the second frame 210 meshing with each other and maintaining a gap in the width direction and sliding parallel to each other in the length direction gives the slidable and expandable barrier stable adjustment and precise guidance capabilities.

[0059] In this embodiment, a sliding guide assembly 700 is also included. The sliding guide assembly 700 is fixedly installed on the first frame 110 and the second frame 210 to keep the first frame 110 and the second frame 210 stable during sliding. The sliding guide assembly 700 includes a plurality of guide elements 710, each guide element 710 including a fixed mounting portion 711 and a sliding mounting portion 712. The first frame 110 includes a first upper member 113 and a first lower member 114, and the second frame 210 includes a second upper member 213 and a second lower member 214. The plurality of fixed mounting portions 711 corresponding to the plurality of guide elements 710 are fixedly connected to the first upper member 113, the first lower member 114, the second upper member 213, and the second lower member 214, respectively. The plurality of sliding mounting portions 712 corresponding to the plurality of guide elements 710 are slidably connected to the first upper member 113, the first lower member 114, the second upper member 213, and the second lower member 214, respectively. With the above-described structure, during use, the sliding guide assembly 700, through the arrangement of multiple guide elements 710, provides stable support for the sliding of the first frame 110 and the second frame 210. The fixed mounting portion 711 of the guide element 710 is rigidly connected to each component of the frame, serving as a mechanical anchor point; the sliding mounting portion 712 slides in contact with each component of the frame, providing stable adjustment and precise guidance capabilities for the slidable and expandable barrier, preventing displacement. The distributed installation of multiple components can distribute the load and reduce wear, and its structural design also supports modular assembly and disassembly.

[0060] In this embodiment, the first upper component 113, the first lower component 114, the second upper component 213, and the second lower component 214 are at least simultaneously fixedly connected to at least one of the fixed mounting portions 711 and slidably connected to at least one of the sliding mounting portions 712. With this structural configuration, in use, the first upper component 113, the first lower component 114, the second upper component 213, and the second lower component 214 form a "fixed + sliding" composite connection mode with the multiple guide elements 710 of the sliding guide assembly 700, significantly improving the stability and structural strength of the barrier sliding. The fixed mounting portions 711 form a rigid connection with each component, ensuring that the guide elements 710 do not undergo overall displacement when the frame slides, providing a stable guiding reference. The sliding mounting portions 712 form a movable connection with each component, allowing the frame to slide relative to each other along its length, while constraining radial (width and height) degrees of freedom through the contact interface. Each of the first upper component 113, the first lower component 114, the second upper component 213, and the second lower component 214 is connected to at least one fixed mounting part 711 (positioning anchor point) and one sliding mounting part 712 (movement fulcrum), forming a "two-point-one-line" guiding constraint to prevent the frame from twisting or shifting during sliding.

[0061] In this embodiment, the contact surface 520 is provided with an anti-slip structure. By providing this structure, the contact surface 520 is equipped with an anti-slip structure during use. The purpose of this structure is to enhance the frictional characteristics of the contact interface, thereby improving the reliability of the barrier installation and preventing functional failure due to slippage.

[0062] In this embodiment, the fixed pressure end member 500 includes a first pressure end member 530 and a second pressure end member 540, which are distributed along the height direction of the second outer end member 211. With this structure, in use, the fixed pressure end member 500 employs a design where the first pressure end member 530 and the second pressure end member 540 are distributed along the height direction of the second outer end member 211. The purpose is to improve the uniformity of contact and the reliability of fixation between the barrier and the target interface through multi-point pressure in the vertical direction. In this embodiment, the first pressure end member 530 and the second pressure end member 540 are distributed on the upper and lower sides of the slidable pressure end member 420 in the height direction.

[0063] In this embodiment, the abutting end 422 is fitted with a soft rubber partition 423. With the above structure, the soft rubber partition 423 on the abutting end 422 during use aims to improve the reliability of the barrier installation and prevent functional failure due to slippage by using a soft rubber partition 423 with a higher coefficient of friction.

[0064] In this embodiment, the first sliding partition 100 further includes a first isolation member 120, which is fixedly connected to the interior of the first frame 110. The second sliding partition 200 further includes a second isolation member 220, which is fixedly connected to the interior of the second frame 210. The first isolation member 120 is used to reduce the barrier gap in the first sliding partition 100, and the second isolation member 220 is used to reduce the barrier gap in the second sliding partition 200. With the above structural configuration, the required barrier gap varies depending on the purpose of the barrier. We can set the first isolation member 120 and the second isolation member 220 with different gaps in the first frame 110 and the second frame 210 according to different needs to meet diverse user requirements. For example, if the barrier is used to prevent small pets from running around, the first isolation member 120 and the second isolation member 220 can be smaller than the size of the small pet.

[0065] In this embodiment, the first isolation member 120 is a rod-shaped element or a mesh element uniformly arranged within the first frame 110, and the second isolation member 220 is a rod-shaped element or a mesh element uniformly arranged within the second frame 210. The uniformly arranged rod-shaped elements refer to those arranged parallel or intersecting along the length or height of the first frame 110 and the second frame 210, forming a linear barrier, as shown in the accompanying drawings of this embodiment. The mesh element refers to a continuous plane composed of interwoven wires (such as metal wires or fiber filaments) that tightly adhere to the inner wall of the frame, such as wire mesh or plastic mesh.
