Abstract
Description
Technical Field
[0001] This utility model relates to the field of child safety protection products, and in particular to a child-proof door gap safety plug to prevent hand pinching. Background Technology
[0002] Accidental closure of doors and windows is a common cause of finger injuries in children at home. To prevent such accidents, parents usually use door safety plugs on the side of the door to ensure a safe gap between the door panel and the frame.
[0003] However, most existing door safety plugs are made of a single type of foam material. Due to their simple structural design, these single-material safety plugs have obvious drawbacks during use: First, their fixing method relies entirely on the elastic friction of the material itself. When the door surface is smooth or subjected to significant vibration, the safety plug is prone to slipping or shifting, leading to protection failure. Second, the structural strength of the single foam material is low, and it is prone to breakage or deformation under long-term repeated compression or the impact of slamming the door. In addition, existing safety plugs lack functional designs for complex home environments and cannot provide security features such as waterproofing, fireproofing, or nighttime warning.
[0004] Therefore, this utility model proposes a child-proof door gap safety plug to address the shortcomings of existing technologies. Utility Model Content
[0005] In view of the common problems of poor fixing stability, easy slippage, low structural strength and easy breakage, and low reliability due to lack of waterproof, fireproof and night warning functions in the existing door gap safety plug, this utility model aims to provide a child anti-pinch door gap safety plug with improved structure that can effectively solve the above problems.
[0006] This utility model provides a child-proof door gap safety plug, comprising: a C-shaped shell, and a magnet disposed on the shell;
[0007] The shell has an opening, and grooves are formed on both sides of the opening. The magnet is embedded in the groove and flush with the inner surface of the shell. The shell wall has a multi-layer composite structure, and the wall includes at least an elastic layer and an anti-slip layer from the outside to the inside. The elastic layer forms the main skeleton of the shell, and the anti-slip layer forms the contact surface on the inner side of the shell. The outer wall of the shell is provided with a number of protrusions, which are arranged at intervals along the outer surface of the shell.
[0008] Furthermore, the magnet and the shell are combined by embedding and adhesive, the elastic layer and the anti-slip layer are combined by lamination, and the protrusion and the elastic layer are connected by integral molding.
[0009] Preferably, the wall of the housing is further combined with a waterproof layer and a flame-retardant layer between the elastic layer and the anti-slip layer. The waterproof layer is attached to the inner side of the elastic layer to prevent water penetration, and the flame-retardant layer is located between the waterproof layer and the anti-slip layer to provide fire protection.
[0010] Preferably, the housing further includes a fluorescent strip disposed on the ridge of the outer wall of the housing to provide a location warning in dim lighting conditions.
[0011] Preferably, the fluorescent strip is located between adjacent protrusions, or the fluorescent strip covers the surface of the protrusions, and the outer wall of the housing is provided with a slot for accommodating the fluorescent strip, and the fluorescent strip is embedded in the slot.
[0012] Preferably, the elastic layer, the waterproof layer, the flame-retardant layer, and the anti-slip layer are laminated into an integral structure by hot pressing or bonding processes.
[0013] Preferably, the protrusion is made of the same material as the elastic layer, and the protrusion serves as a strip-shaped reinforcing rib, with its extension direction perpendicular to or at an inclined angle to the axial direction of the housing.
[0014] Preferably, the magnet is a powerful neodymium iron boron magnet, which is fixed in the groove with strong adhesive and the adsorption surface of the magnet is exposed.
[0015] Preferably, the surface of the anti-slip layer has a grid-like or strip-like anti-slip texture, and the elastic layer is made of EVA foam or silicone material.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model solves the problem that the existing door gap safety plug is easy to slip off and not firmly fixed because it relies on a single friction force for fixation. It achieves the technical effect of using magnetic adsorption and physical anti-slip for dual fixation, which significantly improves the adhesion stability of the device on the door.
[0018] 2. This utility model solves the problem of existing safety plugs having a single material and lacking protective capabilities in extreme environments such as humidity or fire by integrating a waterproof layer and a flame-retardant layer inside the shell wall and adopting a multi-layer composite structure design. It achieves the technical effect of improving the product's weather resistance, antibacterial and mildew prevention capabilities, and fire safety performance.
[0019] 3. This utility model solves the problems of insufficient structural strength and easy breakage of safety plugs and poor nighttime visibility, which pose a collision hazard in the prior art, by setting protrusions and embedded fluorescent strips on the outer wall of the shell. It achieves the technical effect of using protrusions to enhance the structure's impact resistance and buffering capacity, while using fluorescent strips to provide nighttime warning guidance, thus comprehensively protecting the safety of children and family members.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] Example:
[0027] Reference Figures 1 to 3 This utility model provides a child-proof door gap safety plug to prevent finger pinching, aiming to solve the problems of existing door gap safety plugs that are not securely fixed and easily slip off, have low structural strength and are easily broken, and lack fireproof, waterproof and nighttime warning functions.
[0028] like Figure 1 and Figure 2 As shown, the device includes a C-shaped housing 1 and a magnet 2 mounted on the housing 1. The housing 1 serves as the mounting base and core load-bearing component of the entire device, used to clamp onto the edge of a door panel to keep the door open and prevent accidental closure that could pinch a child's fingers. The magnet 2 provides auxiliary adsorption and fixation force when used on iron doors, or allows the device to be adsorbed onto a metal surface for easy storage when not in use, preventing loss.
[0029] Reference Figure 2 and Figure 3 The housing 1 has an opening for clamping the door panel. The two side walls of the opening are respectively provided with mounting grooves. The magnet 2 is embedded in the mounting groove and is fixed to the bottom of the mounting groove by strong adhesive, so that the outer surface of the magnet 2 is flush with the inner surface of the housing 1. This embedded design ensures that the magnet 2 will not protrude from the inner wall of the housing 1, avoiding scratching the surface of the door panel during use.
[0030] The shell 1 has an elastic layer 5, a waterproof layer 6, a flame-retardant layer 7 and an anti-slip layer 8 stacked and fixed from the outside to the inside. These four functional layers are combined into a whole structure by hot pressing or bonding. The elastic layer 5 forms the main skeleton of the shell 1. The elastic layer 5 is made of EVA foam or silicone material and is used to provide the main structural support and elastic recovery force to ensure that the shell 1 can generate sufficient clamping force after being stretched.
[0031] The waterproof layer 6 is coated or bonded to the inner wall of the elastic layer 5 to prevent moisture from penetrating into the interior of the elastic layer 5 and to prevent the material from becoming moldy or aging due to a humid environment. The flame retardant layer 7 is located between the waterproof layer 6 and the anti-slip layer 8. The two sides of the flame retardant layer 7 are bonded and fixed to the waterproof layer 6 and the anti-slip layer 8 respectively, and are used to slow down the burning rate and improve the safety of the product in extreme situations such as fire.
[0032] The anti-slip layer 8 forms the innermost contact surface of the shell 1 that comes into contact with the door. The surface of the anti-slip layer 8 is provided with grid-like protrusions or strip-like protrusions to increase the friction coefficient between the shell 1 and the door panel. Together with the clamping force generated by the elastic layer 5, it ensures that the shell 1 is firmly fixed to the door panel and does not slip off.
[0033] Meanwhile, the outer wall of the elastic layer 5 is integrally formed with several protrusions 3. The protrusions 3 are evenly spaced along the outer surface of the shell 1, and the extension direction of the protrusions 3 is perpendicular to the axial direction of the shell 1 or at an inclined angle. The protrusions 3 serve as strip-shaped reinforcing ribs to disperse external impact forces and work together with the elastic layer 5 to improve the overall fracture resistance and durability of the shell 1.
[0034] A fluorescent strip 4 is also fixedly connected to the outer wall of the housing 1. The fluorescent strip 4 is made of a light-emitting self-luminous material, such as strontium aluminate luminescent material. The fluorescent strip 4 extends longitudinally along the spine of the housing 1 and is located between adjacent protrusions 3, or the fluorescent strip 4 directly covers the surface of the protrusions 3, so that the fluorescent strip 4 can clearly mark the position of the safety plug in the dark environment and play a significant warning role.
[0035] The outer wall of the housing 1 has a slot for accommodating the fluorescent strip 4. The fluorescent strip 4 is embedded in the slot, and the outer surface of the fluorescent strip 4 is not lower than the outer wall surface of the housing 1. That is, the outer surface of the fluorescent strip 4 is flush with or slightly protruding from the outer wall of the housing 1, ensuring that the fluorescent strip 4 can fully receive external light sources for energy storage, while avoiding dust accumulation due to the concavity. The opening width of the housing 1 in its natural state is designed to be less than the thickness of a standard door panel. Utilizing the elastic deformation capability of the elastic layer 5, the housing 1 is stretched open when installed on the door panel, thereby generating a continuous inward clamping force. Combined with the friction of the anti-slip layer 8, it ensures that the device will not slip due to gravity or door vibration. The magnet 2 is preferably fixed to the bottom of the groove with industrial-grade strong adhesive, and the adsorption surface of the magnet 2 is completely exposed on the inner surface of the housing 1 and is not covered by other materials to ensure maximum magnetic conduction. When facing an iron door frame or door panel, the exposed magnet 2 can provide direct adsorption contact.
[0036] The implementation principle of this application embodiment is as follows: When it is necessary to use the child-proof door gap safety plug, the user needs to manually pull the opening of the housing 1 to both sides so that its width is greater than the thickness of the door panel, and then insert the housing 1 into the appropriate height position of the side edge of the door panel. It is generally recommended to install it in a high place that children cannot reach or above the side edge of the door panel.
[0037] When the user releases their hand, due to the excellent elastic recovery properties of the elastic layer 5, the housing 1 attempts to return to its natural, smaller opening width, thereby generating an inward clamping force. This causes the anti-slip layer 8 to adhere tightly to the door panel surface. The friction generated by the anti-slip texture on the surface of the anti-slip layer 8, combined with the clamping force of the elastic layer 5, firmly fixes the safety plug to the door panel. If the door panel is made of iron, the magnet 2 will generate additional magnetic attraction to assist in fixing, further preventing the device from slipping off.
[0038] When the door is blown by the wind or accidentally closed by human force, the housing 1 will contact the door frame before the door panel. Since the housing 1 has a certain thickness and elasticity, and the outer wall is provided with protrusions 3, the protrusions 3 and the elastic layer 5 undergo elastic deformation under force, absorb the impact energy and play a buffering role, preventing the door panel from closing completely, thereby forcibly maintaining a safety gap between the door panel and the door frame. The width of the safety gap is designed to be greater than the thickness of a child's finger, effectively preventing children's fingers from being pinched.
[0039] When the device is not in use, the user can remove it and use the magnets 2 embedded on both sides of the opening to attach the safety plug to the surface of a refrigerator, security door or other metal furniture for storage, which saves space and prevents loss. At night, the light emitted by the fluorescent strip 4 on the outer wall can serve as a good warning to prevent people from accidentally bumping into it.
