It should be noted that the following are only some specific implementation modes of the concept of the present utility model, which are only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and each specific feature does not of course and directly limit the scope of implementation of the present utility model. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model should be regarded as being within the scope of protection required by the present utility model.

[0049] Embodiment 1:

[0050] As Figures 1-8As shown in the figure, the utility model discloses a door gap anti-pinch device, which is used to be installed on one side of the door leaf 91 close to the hinge 94, and includes:

[0051] The mounting seat 1, the rear bottom surface of the mounting seat 1 is fixed on the surface of the door leaf 91 by means of pasting, screws, etc.;

[0052] The protection seat 2, the protection seat 2 is movably arranged on the mounting seat 1, and one end of the protection seat 2 is convexly provided with an anti-pinch head 3. The anti-pinch head 3 is used to be placed in the door gap 92 to limit the complete closing of the door gap 92, so as to prevent the fingers or objects from being pinched in the door gap 92 when closing the door or prevent the door from closing;

[0053] The flipping member 4, the flipping member 4 is pivotally connected to the mounting seat 1 around the axis L1, and the protection seat 2 is pivotally connected to the flipping member 4 around the axis L2; the axis L1 and the axis L2 are not coplanar.

[0054] Among them, the door gap anti-pinch device has Figure 6 the working state shown in the figure and Figure 8 the open state shown in the figure. In the working state, at least part of the anti-pinch head 3 is in the door gap 92, and at this time, the length direction of the protection seat 2 is horizontally oriented. When opening from the working state, the protection seat 2 rotates around the axis L2, and the flipping member 4 rotates around the axis L1, so that the protection seat 2 is changed to the open state. In the open state, the length direction of the protection seat 2 is downward, so as to be in a hanging state.

[0055] Therefore, 1. When the door leaf 91 is opened to generate a door gap 92, and the anti-pinch head 3 is driven to move so that the anti-pinch head 3 is placed in the door gap 92. Thus, when the door leaf 91 suddenly closes and the door gap 92 is closing, the anti-pinch head 3 fills the door gap 92, so that the two surfaces of the door gap 92 cannot be completely attached to make the door gap 92 completely closed, so as to protect the fingers and objects extending into the door gap 92. 2. When the opened door leaf 91 needs to be closed, the anti-pinch head 3 is taken out of the door gap 92 to release the filling of the door gap 92. Thus, the two surfaces of the door gap 92 approach and attach to each other during the closing process to achieve the complete closing of the door gap 92. 3. The protection seat 2 and the flipping member 4 flip around the axis L1 to make the anti-pinch head 3 exit the door gap 92, and the flipping member 4 and the mounting seat 1 flip around the axis L2 to make the protection seat 2 rotate to the vertical position. Under the action of gravity, the protection seat 2 stably hangs to ensure the stability of the state of the protection seat 2, and prevent the protection seat 2 from deflecting and approaching the door gap 92 to affect the opening and closing of the door. 4. The anti-pinch head 3 only needs to fill the door gap 92 to make the door gap 92 unable to be completely closed, so there is no need to completely cover the door gap 92, making the overall volume of the anti-pinch device smaller, thus having lower cost, being convenient for installation, and being stable.

[0056] Preferably, the anti-pinch head 3 is made of a soft rubber material so that the anti-pinch head 3 deforms when pinched. Therefore, during the rapid closing process of the door gap 92, the door frame 93 impacts on the anti-pinch head 3 to convert the impact energy into the deformation potential energy of the anti-pinch head 3, thereby playing a buffering role and protecting the anti-pinch head 3.

[0057] Among them, the rotation angle of the flipping member 4 around the axis L1 is 90° - 360°, and the rotation angle of the protective seat 2 around the axis L2 is 180° - 360°. In this embodiment, both are 360°.

[0058] There are two ways from the working state to the open state, which are respectively:

[0059] The first one, when opening from the Figure 6 shown working state, the protective seat 2 rotates 180° to the right around the axis L2 to the Figure 7 shown state, then the flipping member 4 rotates 90° upward around the axis L1, and then the protective seat 2 rotates downward around the axis L2 so that the anti-pinch head 3 flips and abuts against the door leaf 91 to the Figure 8 shown state.

[0060] The second one, when opening from the working state, the protective seat 2 rotates 180° to the right around the axis L2, and then the flipping member 4 rotates 90° downward around the axis L1, so that the protective seat 2 is vertically attached to the door leaf 91 after flipping.

[0061] Among them, the first way can make the outer surface of the protective seat 2 face outward in both the working state and the open state by flipping the protective seat 2 downward, making the appearance more concise and beautiful. The second one has the advantage of lower center of gravity and greater stability.

[0062] Specifically, the axis L1 is perpendicular to the surface of the door leaf 91, and the axis L2 is perpendicular to the axis L1.

[0063] Preferably, the axis L1 and the axis L2 in this embodiment are eccentrically arranged; and the flipping member 4 is fitted to one end of the protective seat 2; and as Figure 7 shown, the protective seat 2 flips relative to the flipping member 4 so that the anti-pinch head 3 and the axis L2 are on the same side of the axis L1 to form an unfolded state; in addition, as Figure 6 、 Figure 8 shown, the protective seat 2 flips relative to the flipping member 4 so that the anti-pinch head 3 and the axis L2 are on both sides of the axis L1, and the mounting seat 1 is covered by the protective seat 2 to form a covered state.

[0064] Therefore, Figure 6 is the state where the anti-pinch head 3 is placed in the door gap 92, Figure 8 is the hanging state where the anti-pinch head 3 does not need to prevent pinching of the door gap 92. Both are long-term holding states, and Figure 7 is Figure 6 andFigure 8 The temporary state in Figure 7 is such that the mounting base 1 is exposed only in the temporary state, while for the state maintained for a long time Figure 6 , Figure 8 both cover the mounting base 1 with the protective seat 2, making the appearance more concise and beautiful.

[0065] In addition, a locking mechanism 21 is slidably arranged on the protective seat 2. The locking mechanism 21 has a first locking member 211, and a corresponding second locking member 111 is arranged on the mounting base 1. The first locking member 211 is engaged with the second locking member 111 to lock the protective seat 2 and the flipping member 4. In other embodiments, the first locking member 211 and the second locking member 111 can also lock the three components of the mounting base 1, the flipping member 4, and the protective seat 2. Therefore, the relative rotation of the protective seat 2 and the flipping member 4 is limited by the locking mechanism 21, so that in Figure 6 the state shown, the locking mechanism 21 locks the protective seat 2 and the flipping member 4, and the anti-pinch head 3 is stably placed in the door gap 92 for protection, preventing the anti-pinch head 3 from getting out of the door gap 92 and causing the risk of pinching hands during the closing process of the door leaf 91.

[0066] Specifically, the second locking member 111 adopts an annular lock cavity, and the first locking member 211 adopts a lock tongue, so that the lock tongue slides with the locking mechanism 21 and inserts into the lock cavity for cooperative locking, and the lock tongue slides out of the lock cavity with the locking mechanism 21 for unlocking.

[0067] In other embodiments, the second locking member is arranged on the flipping member 4.

[0068] In other embodiments, the locking mechanism 21 adopts a rotating or pressing method to cooperate and separate the first locking member 211 and the second locking member 111.

[0069] Among them, a rotating member 42 is integrally formed on one side of the flipping member 4 and is in the shape of a round rod. Correspondingly, an installation cavity 41 is provided on the protective seat 2. The number of installation cavities 41 is two, and they are respectively located at the two ends of the length of the rotating member 42. The installation cavity 41 includes an insertion cavity 411 and a rotating cavity 412. The insertion cavity 411 and the rotating cavity 412 communicate with each other and have different extending directions to form an L shape. An assembly and disassembly opening 413 is provided at one end of the insertion cavity 411 facing away from the rotating cavity 412. The two ends of the rotating member 42 enter the insertion cavity 411 through the assembly and disassembly opening 413 and then enter the rotating cavity 412 through the insertion cavity 411. In addition, a rear cover plate 23 is provided at the rear side of the protective seat 2. A blocking portion 231 is provided on the rear cover plate 23. The rear cover plate 23 is placed in front of the protective seat 2, and the blocking portion 231 enters the insertion cavity 411. Then, the rear cover plate 23 and the protective seat 2 are detachably connected by means of bolts, buckles, etc. At this time, the blocking portion 231 blocks the intersection of the insertion cavity 411 and the rotating cavity 412 to prevent the rotating member 42 from coming out of the rotating cavity 412, ensuring the stability of the installation of the rotating member 42.

[0070] Among them, the front side of the mounting seat 1 has a cylindrical convex portion. Correspondingly, a cylindrical convex portion is provided on the rear side of the flipping member 4. The cylindrical convex portion of the flipping member 4 is inserted into the cylindrical convex portion of the mounting seat 1 to achieve rotational fit. In addition, bolts, clamping, etc. are used to ensure the stable fit of the two.

[0071] Preferably, in this embodiment, the protective seat 2 includes a rigid body 24 and a soft colloid 25. The anti-pinch head 3 includes a rigid portion 32 located on one side of the rigid body 24 and in an L shape with the rigid body 24, and a soft rubber portion 33 located on one side of the soft colloid 25 and in an L shape with the soft colloid 25. The soft colloid 25 is coated on the rigid body 24 so that the soft rubber portion 33 is coated on the rigid portion 32.

[0072] Therefore, the overall structure is made more stable by the rigid characteristics of the rigid body 24, and the connection strength between the soft rubber portion 33 and the rigid portion 32 is improved by coating the soft colloid 25 on the rigid body 24.

[0073] Among them, the rigid body 24 can be formed by plastic injection molding, and the soft colloid 25 can be formed by injection molding with silicone rubber, etc.

[0074] Among them, the rigid portion 32 is provided with a contact plane 31 for contacting one surface of the door gap 92, and the soft rubber portion 33 is used to receive the impact of the other surface of the door gap 92 during the closing process of the door gap 92.

[0075] Therefore, 1. The abutting plane 31 not only better transmits the impact force to the door leaf 91 when the anti-pinch head 3 is impacted, reducing the force on the mounting base 1 and preventing the mounting base 1 and the door leaf 91 from being separated due to the impact, but also positions the mounting base 1 during installation by first abutting the abutting plane 31 against the door leaf 91 at the door gap 92, and then installing it after determining the position of the mounting base 1, making the installation more convenient. 2. The door gap 92 directly impacts on the soft rubber part 33 made of soft rubber material to prevent hard collision from damaging the anti-pinch head 3.

[0076] Preferably, the hard part 32 is provided with a first plastic-coated surface 321, and a plurality of strip-shaped plastic-coated grooves 322 are arranged on the first plastic-coated surface 321. The soft rubber part 33 is provided with a second plastic-coated surface 331 that is plastic-coated on the first plastic-coated surface 321, and a first plastic-coated rib 332 that fills the plastic-coated grooves 322 is arranged on the second plastic-coated surface 331. Thus, the connection strength of the plastic coating between the hard part 32 and the soft rubber part 33 is improved through the cooperation of the first plastic-coated rib 332 and the plastic-coated grooves 322 on the first plastic-coated surface 321 and the second plastic-coated surface 331.

[0077] Preferably, the hard part 32 is provided with a plastic-coated hole 323 extending along the length direction of the plastic-coated groove 322, and the soft rubber part 33 is provided with a second plastic-coated rib 333 that fills the plastic-coated hole 323, so as to further improve the connection strength of the plastic coating between the hard part 32 and the soft rubber part 33 through the cooperation of the plastic-coated hole 323 and the second plastic-coated rib 333.

[0078] Preferably, a deformation cavity 34 is arranged on the soft rubber part 33 in this embodiment, so that the deformation cavity 34 provides a deformation space when the soft rubber part 33 is deformed by impact, further improving the impact resistance of the anti-pinch head 3.

[0079] Embodiment 2:

[0080] As Figures 9-14 shown, the present utility model discloses a door gap anti-pinch device for being installed on one side of the door leaf 91 close to the hinge 94, including:

[0081] A mounting base 1, which is fixed on the surface of the door leaf 91 by means of pasting, screws, etc.;

[0082] A protective seat 2, which is movably arranged on the mounting base 1. An anti-pinch head 3 protrudes from the protective seat 2, and the anti-pinch head 3 is used to be placed in the door gap 92 to limit the complete closing of the door gap 92, so as to prevent the door gap 92 from pinching hands when closing the door or prevent the door from closing.

[0083] Specifically, the protective seat 2 includes a first seat body 201, a second seat body 202 and a third seat body 203. The first seat body 201 is pivotally connected to the mounting seat 1 around the axis L1, and the axis L1 is perpendicular to the surface of the door leaf 91. The anti-pinch head 3 is connected to or integrally formed with the third seat body 203. The second seat body 202 is made of a soft material, and the soft material can be made of soft rubber or other materials.

[0084] Among them, the door gap anti-pinch device has Figure 13 the working state shown in Figure 14 and the open state shown in. In the working state, at least part of the anti-pinch head 3 is located in the door gap 92, and at this time, the length direction of the protective seat 2 is horizontally oriented. When opening from the working state, the protective seat 2 rotates around the axis L1 so that the protective seat 2 is changed to the open state. During the process, the second seat body 202 is bent and deformed, and the anti-pinch head abuts against the surface of the door leaf 91. In the open state, the length direction of the protective seat 2 is arranged downward to be in a hanging state.

[0085] Therefore, 1. When a door gap 92 is generated after the door leaf 91 is opened, and the anti-pinch head 3 is driven to move so that the anti-pinch head 3 is placed in the door gap 92, when the door leaf 91 suddenly closes and the door gap 92 is closed, the anti-pinch head 3 fills the door gap 92 so that the two surfaces of the door gap 92 cannot be completely attached to make the door gap 92 completely closed, so as to protect the fingers and objects extending into the door gap 92. 2. When the opened door leaf 91 needs to be closed, the anti-pinch head 3 is taken out of the door gap 92 to relieve the filling of the door gap 92, so that the two surfaces of the door gap 92 approach and fit each other during the closing process to achieve the complete closing of the door gap 92. 3. The second seat body 202 itself is made of a soft material, so that the anti-pinch head 3 can be taken out of the door gap 92 by pulling the anti-pinch head 3 outward. Correspondingly, the second seat body 202 is deformed, and then the third seat body 203 is driven to rotate relative to the mounting seat 1 so that the protective seat 2 is turned downward to the vertical position. Under the action of gravity, the protective seat 2 is stably suspended to ensure the stability of the state of the protective seat 2 and prevent the protective seat 2 from deflecting and approaching the door gap 92 to affect the opening and closing of the door. At this time, the second seat body 202 makes the anti-pinch head 3 abut against the surface of the door leaf 91 through elastic reset, further improving the stability of the protective seat 2 in the open state. 4. The anti-pinch head 3 only needs to fill the door gap 92 to make the door gap 92 unable to be completely closed, so there is no need to completely cover the door gap 92, making the overall volume of the anti-pinch device smaller, thus having lower cost, being convenient for installation, and being stable.

[0086] Preferably, the anti-pinch head 3 is made of a soft rubber material so that the anti-pinch head 3 deforms when being pinched. Therefore, during the rapid closing process of the door gap 92, the door frame 93 impacts on the anti-pinch head 3 to convert the impact energy into the deformation potential energy of the anti-pinch head 3, thus playing a buffering role and protecting the anti-pinch head 3.

[0087] Specifically, the mounting base 1 includes a base 13 and a fastening cover 14. The rear side of the base 13 is circular and fixed to the surface of the door leaf 91 by means of glue or the like. An installation post 132 is integrally formed on the front side of the circular sheet of the base 13. Correspondingly, the first seat body 201 is provided with a rotation through hole 2011, so that the first seat body 201 is rotationally mounted on the base 13 through the cooperation of the installation post 132 and the rotation through hole 2011. In addition, the fastening cover 14 and the base 13 are respectively located on the front and rear sides of the first seat body 201 to clamp and limit the first seat body 201. In addition, an assembly part 141 is integrally formed on the rear side of the fastening cover 14, and the assembly part 141 is in threaded cooperation with the installation post 132 to fixedly install the base 13 and the fastening cover 14.

[0088] In addition, on the front side of the circular sheet of the base 13 in this embodiment, 4 installation protrusions 131 are circumferentially arranged around the installation post 132. 4 installation grooves 271 are provided on the rear side of the first seat body 201. The installation protrusions 131 and the installation grooves 271 are clamped to limit the relative rotation of the protective seat 2 and the mounting base 1, thereby further ensuring Figure 13 the stability of the anti-pinch head 3 shown in the door gap 92 and Figure 14 the stability of the protective seat 2 shown in the hanging state.

[0089] Preferably, both the protective seat 2 and the anti-pinch head 3 in this embodiment are made of soft rubber materials such as silica gel, and the protective seat 2 and the anti-pinch head 3 are integrally formed. This makes the number of parts less and the overall structure more concise.

[0090] Among them, the anti-pinch head 3 is provided with an abutting plane 31 for abutting against the side surface of the door leaf 91.

[0091] Therefore, not only does the abutting plane 31 better transfer the impact force to the door leaf 91 when the anti-pinch head 3 is impacted, reducing the force on the mounting base 1 and preventing the mounting base 1 and the door leaf 91 from being separated by the impact, but also during installation, the position is first located by the abutting of the abutting plane 31 and the door leaf 91 at the door gap 92, and then the mounting base 1 is installed after determining its position, making the installation more convenient.

[0092] Preferably, a deformation cavity 34 is provided on the anti-pinch head 3 in this embodiment, so that the deformation cavity 34 provides a deformation space when the soft rubber part 33 is deformed by impact, further improving the anti-impact ability of the anti-pinch head 3.
