Description

Technical Field

[0001] This utility model relates to the field of household products technology, and in particular to a door that prevents hands from being pinched. Background Technology

[0002] Doors are common household items. The door body is connected to the door frame by hinges, and the gap between the side wall of the door body and the inner wall of the door frame is small.

[0003] When a door is closed, a person's hand may occasionally get caught between the door and the door frame. This risk is especially high for families with children, and a child's hand getting caught can easily lead to serious consequences. Therefore, there is a need in the market for a door that prevents hand pinching to improve the safety of door use. Summary of the Invention

[0004] The purpose of this invention is to provide a door that prevents children's hands from getting pinched.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A door designed to prevent hand pinching includes a door body with a flexible hand guard attached to it. The door body also has mounting grooves on both sides, and a flexible hand guard is attached to each of the mounting grooves on both sides. The flexible hand guard is made of a flexible and elastic material such as rubber.

[0007] Furthermore, the door body is connected to a positioning hinge, which includes a short hinge plate and a long hinge plate. The short hinge plate and the long hinge plate are rotatably connected. The short hinge plate is used to connect to the door frame, and the end of the long hinge plate away from the short hinge plate is connected to the door body. The middle part of the long hinge plate is used to cover the flexible handguard on the adjacent side to protect the flexible handguard.

[0008] Furthermore, the flexible hand guard body has a positioning strip on its side wall and a positioning groove on the inner wall of the mounting groove. The positioning strip and the positioning groove have a curved cross-section and are compatible with each other. The maximum inner diameter of the positioning groove is greater than the opening width of the positioning groove. The positioning strip is inserted into the positioning groove to achieve the positioning and installation of the flexible hand guard body in the mounting groove.

[0009] Furthermore, a protective layer is connected to the positioning groove and the installation groove. The protective layer is attached to and fixedly connected to the inner wall of the positioning groove and the installation groove. The protective layer can be connected by adhesive or screws. The protective layer is a plastic metal sheet. The interior of the door is mostly made of wood. After the groove is cut, the wood material on the inner wall of the groove is directly exposed to the air and is easily damaged by moisture. The protective layer protects the wood material on the inner wall of the groove.

[0010] Furthermore, the lower ends of the mounting groove and positioning groove extend through to the lower wall of the door. During installation, the flexible handguard is inserted directly into the mounting groove from the lower end of the door upwards, while the positioning strip is inserted into the positioning groove. This avoids the positioning strip being directly squeezed into the positioning groove from the opening of the positioning groove, thus reducing damage to the positioning strip.

[0011] Furthermore, the protective layer sidewall is provided with limiting protrusions, and the flexible handguard body sidewall is provided with limiting grooves. The limiting protrusions are embedded in the limiting grooves. After the flexible handguard body is inserted into the mounting groove, the limiting protrusions are embedded in the limiting grooves, providing support and friction in the length direction of the door body, thereby improving the installation stability of the flexible handguard body.

[0012] Furthermore, a transition layer connects the positioning strip and the flexible handguard body. A transition groove is provided at the groove opening of the door body near the positioning groove. The transition groove communicates with the positioning groove, and the protective layer is also connected to the inner wall of the transition groove. Since the side wall of the positioning strip is arc-shaped, if it is directly connected to the side wall of the flexible handguard body, the included angle between them is small, making it easy to tear under the action of lateral force. The setting of the transition layer reduces the included angle when the positioning strip is connected, reducing the possibility of the positioning strip being torn under the action of lateral force.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When a child's hand is trapped between the door and the door frame, the flexible hand guard replaces the edge of the door. When the child's hand is trapped, the flexible hand guard deforms elastically, preventing excessive pressure on the hand and thus improving the safety of the door during use.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.

[0020] See Figure 1-2 The present invention provides a technical solution for an anti-pinch door, comprising a door body 1 and a door frame 5. The door body 1 is rotatably connected to the door frame 5. The door body 1 has mounting grooves 11 on both sides along its own length direction. The inner wall of the mounting groove 11 has a positioning groove 12 along its own length direction. The door body 1 has a transition groove 13 near the groove opening of the positioning groove 12. A flexible hand guard 2 is connected in the mounting groove 11. The flexible hand guard 2 is made of a flexible and elastic material such as rubber. A positioning strip 21 is fixedly provided on the side wall of the flexible hand guard 2. A transition layer 22 is connected between the positioning strip 21 and the flexible hand guard 2. The transition layer 22, the positioning strip 21 and the flexible hand guard 2 are integrally formed. The width of the transition layer 22 is 3-5 mm. In this embodiment, it is set to 4 mm.

[0021] Preferably, the lower ends of the mounting groove 11, positioning groove 12 and transition groove 13 are all extended to the lower end wall of the door body 1. The same protective layer 3 is connected in the mounting groove 11, positioning groove 12 and transition groove 13. The protective layer 3 is a metal sheet with a certain plasticity. The protective layer 3 is connected in the mounting groove 11, positioning groove 12 and transition groove 13 by adhesive.

[0022] Preferably, the cross-sections of the positioning strip 21 and the positioning groove 12 are both of the shape of an arc and are compatible with each other. The shape of an arc refers to an arc with an arc greater than a semicircle. The maximum inner diameter of the positioning groove 12 is greater than the opening width of the positioning groove 12, so that the positioning strip 21 can be stuck in the positioning groove 12 in the horizontal direction to achieve the positioning of the flexible hand guard 2.

[0023] Preferably, the protective layer 3 has integrally formed limiting protrusions 31 on its sidewall, and the flexible hand guard 2 has a limiting groove 23 on its sidewall, with the limiting protrusions 31 embedded in the limiting groove 23.

[0024] Before installing the door body 1 to the door frame 5, the flexible handguard 2 is moved and inserted into the installation groove 11. Simultaneously, the positioning strip 21 is inserted into the positioning groove 12, and the transition layer 22 is inserted into the transition groove 13. As the flexible handguard 2 moves, the limiting protrusion 31 presses against it. After the flexible handguard 2 is in place, the limiting protrusion 31 is embedded in the limiting groove 23, providing support and friction along the length of the flexible handguard 2, thus completing the installation of the flexible handguard 2. When a child's hand is trapped between the door body 1 and the door frame 5, the flexible handguard 2 replaces the edge of the door body 1. When a child's hand is trapped, the flexible handguard 2 undergoes elastic deformation, preventing excessive pressure on the hand and thus improving the safety of the door body 1 during use.

[0025] A positioning hinge 4 is connected to the door body 1. The positioning hinge 4 includes a short hinge plate 41 and a long hinge plate 42. The short hinge plate 41 and the long hinge plate 42 are rotatably connected. The short hinge plate 41 is fixedly connected to the door frame 5 by screws. The end of the long hinge plate 42 away from the short hinge plate 41 is fixedly connected to the door body 1. The middle part of the long hinge plate 42 is used to cover the flexible handrail body 2 on the adjacent side.
