Screen connecting structure

Abstract

The utility model discloses a screen connecting structure, and belongs to the technical field of screens. In order to solve the problem that in the prior art, a screen clamps hands, an elastic connecting plate is in linkage with a sleeve type cylinder transmission structure, and a self-adaptive buffering mechanism is constructed at a screen connecting joint. And when the connecting part is clamped by external force, the elastic connecting plate automatically deforms to absorb impact energy, so that the clamping risk and part damage are effectively eliminated. The magnetic attraction locking assemblies are matched with the notches through the movable hinges, the linear stability of the screen in the unfolded state is ensured, and meanwhile single-hand rapid folding operation is achieved. The full-covering design of the cover plate on the inserting gap thoroughly avoids the hidden danger of hand clamping, and the symmetrically distributed sleeve assemblies enable buffering force to be transmitted evenly and reliably. On the premise that the basic function of the screen is maintained, the safety protection performance and the use reliability are remarkably improved through the overall structure.

Description

Technical Field

[0001] This utility model belongs to the field of screen technology, specifically relating to a screen connection structure. Background Technology

[0002] Current screen connection structures generally employ a rigid locking design, preventing buffering displacement between adjacent screens. When a screen traps a person (especially a child's finger) or a foreign object during opening and closing, the rigid connection directly transmits the impact force to the frame, easily causing pinching injuries and structural deformation. While existing technologies attempt to add protective layers, they fail to fundamentally solve the problem of insufficient flexibility at the connection points, still posing serious safety hazards under sudden external forces. Therefore, there is an urgent need for a screen connection structure that can actively absorb impact energy and provide a flexible buffering mechanism.

[0003] This utility model attempts to solve or at least alleviate problems such as fingers being pinched by screens by providing a screen connection structure. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a screen connection structure with the advantage of preventing pinching injuries.

[0005] To achieve the above objectives, this utility model provides a screen connection structure, including a side screen, a central screen, first insertion frames symmetrically arranged on both sides of the central screen, a first plug-in inserted into the first insertion frame, a first column connected to the end of the first plug-in, a second insertion frame arranged on the side screen, a second plug-in inserted into the second insertion frame, a second column connected to the end of the second plug-in, a first sleeve sleeved on the outside of the first column, a second sleeve sleeved on the outside of the second column, and an elastic connecting plate connecting the second sleeve and the first sleeve.

[0006] As a further improvement of this utility model, it also includes a cover plate, which is detachably covered at the connection between the second plug-in frame and the second plug-in, or at the connection between the first plug-in frame and the first sleeve.

[0007] As a further improvement of this utility model, the side of the side screen is provided with a magnetic buckle, the magnetic buckle includes a fixed plate fixed to the side wall of the second insertion frame, a movable plate connected to the fixed plate by a hinge, and a slot provided on the side of the movable plate; a magnetic sheet that magnetically engages with the slot is fixed on the side of the first insertion frame.

[0008] As a further improvement of this utility model, the magnetic sheet can be adsorbed into the slot to keep the unfolded screen in a straight line.

[0009] As a further improvement of this utility model, the bottom of both the side screen and the central screen is provided with multiple threaded holes, and universal wheels can be detachably installed in the threaded holes.

[0010] As a further improvement of this utility model, the elastic connecting plate is an arc-shaped spring sheet, whose elastic deformation provides a buffer space when the side screen and the middle screen rotate relative to each other.

[0011] As a further improvement of this utility model, the second sleeve and the first sleeve are symmetrically arranged with the elastic connecting plate as the axis.

[0012] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0013] This invention innovatively couples a sleeve-type column structure with an elastic connecting plate, constructing an adaptive deformation mechanism at the screen connection node. When the connection is subjected to a sudden clamping force, this mechanism actively absorbs the impact energy through elastic deformation, significantly reducing the risk of pinching injury and component breakage, fundamentally overcoming the violent transmission defects of traditional rigid connections. The magnetic locking component adopts a design of movable hinges and slots, achieving multi-point adsorption and fixation in the unfolded state of the screen, ensuring absolute stability of the linear arrangement; while in the folding operation, only a single-handed pressing action is needed to quickly release the magnetic constraint, significantly improving ease of use. The detachable universal wheel module achieves high compatibility through standardized threaded interfaces, adapting to smooth movement on hard surfaces and maintaining steering flexibility in complex scenarios such as carpeting. The cover plate's full coverage design of the interlocking gaps completely eliminates the risk of dust accumulation, and its modular disassembly and assembly characteristics simultaneously simplify the maintenance process. The symmetrically distributed sleeve components make the transmission of buffer force more balanced, avoiding unilateral overload deformation and significantly extending the structural life. While maintaining the basic functions of the screen, the overall solution achieves breakthrough improvements in safety, adaptability, and durability through the synergistic effect of multi-level protection mechanisms, making it particularly suitable for high-sensitivity application scenarios such as children's activity areas and exhibition partitions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0026] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0027] This utility model provides a screen connection structure, including a side screen 1, a central screen 2, first insertion frames 3 symmetrically arranged on both sides of the central screen 2, a first plug-in 4 inserted into the first insertion frame 3, a first column 6 connected to the end of the first plug-in 4, a second insertion frame 15 disposed on the side screen 1, a second plug-in 16 inserted into the second insertion frame 15, a second column 5 connected to the end of the second plug-in 16, a first sleeve 8 sleeved on the outside of the first column 6, a second sleeve 7 sleeved on the outside of the second column 5, and an elastic connecting plate 9 connecting the second sleeve 7 and the first sleeve 8. The elastic connecting plate 9 and the non-rigid connections between the components provide sufficient flexibility at the screen connection point, enabling cushioning when objects are caught.

[0028] As a preferred embodiment of this utility model, it further includes a cover plate 10, which is detachably positioned to cover the connection between the second plug-in frame 15 and the second plug-in 16, or to cover the connection between the first plug-in frame 3 and the first sleeve 8. The cover plate prevents dust from falling in.

[0029] In a preferred embodiment of this invention, the side panel 1 is provided with a magnetic snap fastener 11. The magnetic snap fastener 11 includes a fixed plate 111 fixed to the side wall of the second insertion frame 15, a movable plate 112 connected to the fixed plate 111 via a hinge 113, and a slot 114 provided on the side of the movable plate 112. A magnetic sheet 12 is fixedly provided on the side of the first insertion frame 3, which magnetically engages with the slot 114. The magnetic attraction ensures that the panel remains stable after it is unfolded.

[0030] In a preferred embodiment of this invention, the magnetic sheet 12 can be adsorbed into the slot 114 to keep the unfolded screen in a straight line. Upon adsorption, the connection is more stable due to the combined effects of magnetic force and the slot structure.

[0031] In a preferred embodiment of this utility model, both the side screen 1 and the central screen 2 are provided with multiple threaded holes 13 at their bottoms, and universal wheels 14 can be detachably installed in the threaded holes 13. The universal wheels ensure that the screens can be moved freely.

[0032] In a preferred embodiment of this invention, the elastic connecting plate 9 is an arc-shaped spring sheet, whose elastic deformation provides a buffer space when the side screen 1 and the central screen 2 rotate relative to each other. The spring sheet has sufficient elasticity, resulting in a better anti-pinch effect.

[0033] In a preferred embodiment of this invention, the second sleeve 7 and the first sleeve 8 are symmetrically arranged with the elastic connecting plate 9 as the axis. This symmetrical arrangement makes the structure of this invention more rational and easier to fold.

[0034] Working principle:

[0035] A second insertion frame 15 is provided on the edge of the side screen 1, and a second plug-in 16 is inserted into the second insertion frame 15. The end of the second plug-in 16 is connected to the second column 5, and a second sleeve 7 is fitted on the outside of the second column 5. First insertion frames 3 are symmetrically arranged on both sides of the middle screen 2. First plug-in 4 is inserted into the first insertion frame 3, and the end of the first plug-in 4 is connected to the first column 6. A first sleeve 8 is fitted on the outside of the first column 6. The second sleeve 7 and the first sleeve 8 are connected by an elastic connecting plate 9 to form a flexible transmission node. When the screen is unfolded, the magnetic sheet 12 on the side of the first insertion frame 3 is embedded in the slot 114 of the movable plate 112 of the magnetic buckle 11, and the screen is kept in a straight state by magnetic attraction. When folded, the movable plate 112 is pressed down to release the magnetic attraction constraint, and the side screen 1 and the middle screen 2 rotate relative to each other. The elastic connecting plate 9 produces an arc deformation to provide a buffer space. If a foreign object is caught, the deformation of the elastic connecting plate 9 absorbs the impact force to avoid hard squeezing. The cover plate 10 covers the connection gap between the second plug-in frame 15 and the second plug-in 16 or the first plug-in frame 3 and the first sleeve 8 to prevent fingers from being pinched and dust from entering. The threaded hole 13 at the bottom of the screen can be used to install casters 14. The symmetrically distributed second sleeve 7 and first sleeve 8 ensure balanced transmission of cushioning force during movement.

[0036] In summary, this utility model innovatively constructs an adaptive deformation mechanism at the screen connection node by coupling a sleeve-type column structure with an elastic connecting plate. When the connection is subjected to a sudden clamping force, this mechanism actively absorbs the impact energy through elastic deformation, significantly reducing the risk of pinching injury and the probability of component breakage, fundamentally overcoming the violent transmission defects of traditional rigid connections. The magnetic locking component adopts a design that combines a movable hinge with a slot, achieving multi-point adsorption and fixation when the screen is unfolded, ensuring the absolute stability of the linear arrangement; while during folding operations, only a single-handed pressing action is needed to quickly release the magnetic constraint, significantly improving ease of use. The detachable universal wheel module achieves high compatibility through a standardized threaded interface, adapting to smooth movement on hard surfaces and maintaining steering flexibility in complex scenarios such as carpeting. The cover plate's full coverage design of the interlocking gaps completely eliminates the risk of dust accumulation, and its modular disassembly and assembly characteristics simultaneously simplify the maintenance process. The symmetrically distributed sleeve components make the transmission of buffer force more balanced, avoiding unilateral overload deformation and significantly extending the structural life. While maintaining the basic functions of the screen, the overall solution achieves breakthrough improvements in safety, adaptability, and durability through the synergistic effect of multi-level protection mechanisms, making it particularly suitable for high-sensitivity application scenarios such as children's activity areas and exhibition partitions.
