Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] The blocking device according to a first aspect embodiment of the present invention will now be described with reference to the accompanying drawings. It should be noted that in practical applications of the blocking device, the first direction can be left-right, the second direction can be up-down, and the third direction can be front-back. The first, second, and third directions intersect each other.

[0036] This utility model embodiment provides a blocking device 10 for preventing a door from opening, see reference. Figures 1 to 4 As shown, the blocking device 10 includes a base 100, a movable member 200, and a supporting member 300. The base 100 includes a connected base 110 and a connecting portion 120. The base 110 supports the connecting portion 120 and other components of the blocking device 10. In use, the base 110 contacts the ground to generate friction, thus preventing the door from opening. The connecting portion 120 extends along a first direction and has multiple limiting blocks 121. These limiting blocks 121 are spaced apart along a second direction, with the spacing between each limiting block 121 being the same.

[0037] The movable member 200 is connected to the connecting portion 120. The movable member 200 includes an adjustment portion 210, which is disposed along a first direction on the side of the movable member 200 facing the connecting portion 120. At least a portion of the adjustment portion 210 is connected to one or more of a plurality of limiting blocks 121, thereby allowing the movable member 200 to move relative to the connecting portion 120 along a second direction via the adjustment portion 210.

[0038] The abutment member 300 is connected to the movable member 200. An abutment portion 310 is provided on the side of the abutment member 300 opposite to the movable member 200, and the abutment portion 310 is arranged along a first direction. The abutment portion 310 is used to abut against the bottom of the door body. Since the abutment member 300 is connected to the movable member 200, when the movable member 200 moves relative to the connecting portion 120 along a second direction via the adjusting portion 210, the abutment member 300, driven by the movable member 200, will also move along the second direction relative to the connecting portion 120, thereby realizing the raising and lowering of the abutment portion 310.

[0039] In one example, specifically, when the blocking device 10 is used to obstruct the door, the base 110 needs to contact the ground to generate friction. The abutment portion 310 is located at the bottom of the door, i.e., in the gap between the door and the ground. Then, by driving the movable member 200 to move, the movable member 200 moves relative to the connecting portion 120 in the second direction with the cooperation of the adjusting portion 210 and the limiting block 121, thereby driving the abutment portion 310 to rise and fall relative to the connecting portion 120, achieving contact between the abutment portion 310 and the bottom of the door, so that the blocking device 10 can be applied to doors with different gap heights from the ground. Since a force is generated between the abutment portion 310 and the door after they come into contact, the force between the abutment portion 310 and the door can be changed by adjusting the tightness of the abutment portion 310 against the door. If the force between the abutment part 310 and the door increases, the door will exert a downward force on the abutment part 310, which will be transmitted to the base 100 through the connecting part 120. Since the base 100 is in contact with the ground, this force will be applied to the ground, and the ground will react on the base 100, applying another force of equal magnitude but opposite direction. Therefore, by adjusting the abutment part 310, the force between the blocking device 10 and the door can be changed, thereby improving the blocking effect.

[0040] The blocking device 10 of this embodiment of the invention, through the engagement of the adjusting part 210 and the limiting block 121, allows the movable part 200 to drive the supporting part 300 to move in the second direction, thereby realizing the raising and lowering of the abutment part 310 and making the blocking device 10 adaptable to different door types. Furthermore, by raising the abutment part 310 to contact the door and the base 110 to contact the ground, the interaction force between the abutment part 310 and the door, and between the base 110 and the ground, can be controlled, thereby increasing the connection strength between the blocking device 10 and the door and the ground respectively, thus improving the blocking effect.

[0041] In some embodiments, see Figure 1 , Figure 3 and Figure 6As shown, the interior of the abutment 300 is a hollow structure, which defines a receiving cavity 320. The receiving cavity 320 has openings 321 on both sides (i.e., the upper and lower sides) of the abutment 300 along a second direction. A connecting portion 120 is disposed within the receiving cavity 320, and a portion of the connecting portion 120 extends out of the receiving cavity 320 through the openings 321. Specifically, the abutment 300 is fitted onto the outside of the connecting portion 120 through the receiving cavity 320 and the openings 321. When the abutment 300 is driven by the movable member 200, the abutment 300 moves relative to the connecting portion 120 along the second direction through the openings 321, preventing the connecting portion 120 from obstructing the abutment 300 during movement. Meanwhile, by assembling the connecting part 120 into the receiving cavity 320, the space required for assembling the base 100, the movable part 200 and the supporting part 300 can be reduced, thereby reducing the volume of the braking device 10 and facilitating the miniaturization of the braking device 10 for easy carrying.

[0042] Furthermore, in some embodiments, see [reference] Figures 1 to 6 As shown, the sidewall of the connecting portion 120 is recessed in the third direction to form a groove 122, and the inner wall of the abutment 300 is provided with a slider 330 in the third direction. Specifically, when the connecting portion 120 passes through the receiving cavity 320 inside the abutment 300, the slider 330 will be accommodated in the groove 122. When the abutment 300 is driven by the movable member 200 to move relative to the connecting portion 120 in the second direction, the slider 330 will also move along the path of the groove 122 in the second direction, thereby providing a guiding function for the lifting and lowering of the abutment portion 310.

[0043] Furthermore, through the cooperation of the slider 330 and the groove 122, the connecting part 120 can limit the abutment 300 in the first direction and the third direction. Specifically, one side of the groove 122 has an inlet and outlet along the third direction through the connecting part 120. The sidewalls at the inlet and outlet extend towards each other in the first direction, so that the width of the inlet and outlet in the first direction is less than the width of the slider 330 in the first direction, thereby allowing the slider 330 to enter and exit the groove 122 only through the vertical opening of the groove 122. When the slider 330 is accommodated in the groove 122, the inner wall of the groove 122 will hinder the slider 330 from moving in the left-right and front-back directions, preventing the slider 330 from disengaging from the groove 122 when the abutment 300 moves relative to the connecting part 120, thereby limiting the slider 330 and improving the connection strength between the abutment 300 and the connecting part 120.

[0044] In some embodiments, the movable member 200 is slidably connected to the connecting portion 120. The adjusting portion 210 can extend and retract relative to the movable member 200 along a first direction to achieve a detachable connection with the limiting block 121. When the connecting portion 120 and the movable member 200 are fixedly connected, the adjusting portion 210 is positioned between two adjacent limiting blocks 121 to keep the connecting portion 120 and the movable member 200 relatively stationary. When it is necessary to drive the movable member 200 to move relative to the connecting portion 120 along the first direction, the adjusting portion 210 retracts relative to the movable member 200 to separate from the limiting block 121, at which point the movable member 200 can slide relative to the connecting portion 120 along the first direction. After sliding to a designated position, the adjusting portion 210 extends relative to the movable member 200 to be fixed between two adjacent limiting blocks 121, thereby enabling the movable member 200 to move relative to the connecting portion 120 along a second direction to raise and lower the abutment portion 310.

[0045] In another embodiment, the movable member 200 is rotatably connected to the connecting portion 120. The movable member 200 has a central axis, and the adjusting portion 210 can rotate relative to the limiting block 121 about the central axis. During rotation, the adjusting portion 210 contacts different limiting blocks 121, thereby enabling the movable member 200 to move relative to the connecting portion 120 in a second direction to raise or lower the abutment portion 310. For example, the limiting block 121 and the adjusting portion 210 are gear-driven. Specifically, in one example, the limiting block 121 is a gear tooth, with the teeth spaced apart on the connecting portion 120. The adjusting portion 210 is a gear structure. The adjusting portion 210 is rotatably mounted on the movable member 200. The central axis of the movable member 200 is arranged in a third direction. The adjusting portion 210 can rotate relative to the connecting portion 120 about the central axis to engage with different limiting blocks 121, thereby enabling the movable member 200 to move relative to the connecting portion 120 in a second direction to raise or lower the abutment portion 310.

[0046] In another embodiment, the adjusting part 210 has a curved structure 220 that rotates around the same axis O, and the distances between each point on the curved structure 220 and the axis O are not equal. For example, the curved structure 220 is a cam structure. The central axis of the movable member 200 is set along a third direction and does not change with the rotation of the curved structure 220. The outer wall of the cam structure abuts against the limiting block 121. When the cam structure rotates relative to the adjusting part 210, the distance from the edge of the cam structure to the axis O is different, so the movable height of the movable member 200 will also change differently under the rotation of the cam structure, thereby causing the movable member 200 to move relative to the connecting part 120 in a second direction to raise and lower the abutting part 310.

[0047] In some embodiments, see Figure 4 and Figure 8As shown, the adjustment part 210 is arranged in a spiral shape. Specifically, as... Figure 8 As shown, Figure 8 The dot in the diagram represents the axis O. As the curved structure 220 rotates, the distance between each point and the axis O gradually increases, thus achieving the rotation of the curved structure 220. In other words, the curved structure 220 gradually expands around the axis, rotating in concentric circles. It should be noted that when the adjusting part 210 is helical, the angle of rotation of the helix needs to exceed 180 degrees, i.e.: [Example from another diagram] Figure 8 As shown, Figure 8 Points C1 and E are two points on a straight line passing through axis O. When the spiral rotates from point C1 to point E, the angle of rotation of the bending structure 220 is 180 degrees. Using points C1 and E as references, when the adjusting part 210 rotates relative to the connecting part 120, when point C1 contacts one of the limiting blocks 121, point E will also contact the other limiting block 121. However, as the adjusting part 210 rotates, points C1 and E will simultaneously separate from the limiting blocks 121. Therefore, the angle of rotation of the spiral needs to exceed 180 degrees to prevent both ends of the adjusting part 210 from simultaneously separating from the limiting blocks 121, thus avoiding the situation where the adjusting part 210 detaches from the limiting blocks 121.

[0048] Furthermore, in some embodiments, the curved structure 220 is an equidistant spiral structure, with each corresponding pair of positions of the curved structure 220 having the same spacing. That is, a ray extending from the axis O will intersect the curved structure 220 at points such as C1 and D1, and C2 and D2. Since points C1 and D1 can be the start and end points of a circle, or points C2 and D2 can also be the start and end points of a circle, points C1 and D1 are defined as corresponding points, and points C2 and D2 are defined as corresponding points. The distance between points C1 and D1 is defined as a first length L1, and the distance between points C2 and D2 is defined as a second length L2. The first length L1 is equal to the second length L2. By making the first length L1 equal to the second length L2, when the adjusting part 210 rotates relative to the connecting part 120, the movable part 200 will move the same distance along the first direction after the adjusting part 210 rotates by the same angle, thereby making the lifting and lowering of the abutment part 310 more uniform and facilitating the user to adjust the braking device 10.

[0049] In other embodiments, the curved structure 220 can also be an unequal-pitch helical structure. When the adjusting part 210 rotates twice, and the two rotation angles are the same, the movable member 200 will have different active heights along the first direction under the two rotations of the adjusting part 210. Using an unequal-pitch helical structure can also achieve the same effect of driving the movable member 200 to move along the first direction through the adjusting part 210, thereby driving the abutment part 310 to rise and fall.

[0050] In some embodiments, see Figure 3 , Figure 4 and Figure 7 As shown, the adjusting part 210 is inclined relative to the connecting part 120, that is, there is an angle between the plane where the adjusting part 210 is located and the plane where the connecting part 120 is located. Specifically, by the adjusting part 210 being inclined to the connecting part 120, a part (upper side) of the adjusting part 210 can be connected to the limiting block 121, and the other part (lower side) can be separated from the limiting block 121.

[0051] When the adjusting part 210 rotates relative to the connecting part 120 to allow the movable member 200 to move in the second direction, since the adjusting part 210 has a spiral structure, the limiting block 121 will contact the inner wall of the adjusting part 210 after contacting the adjusting part 210. Using the adjusting part 210 as a reference, the limiting block 121 will move along the inner wall of the adjusting part 210 as the adjusting part 210 rotates, thereby allowing the movable member 200 to move relative to the connecting part 120 in the second direction. By separating the lower part of the adjusting part 210 from the limiting block 121 and preventing contact with it, the limiting block 121 can move a certain distance along the inner wall of the adjusting part 210 before separating from the adjusting part 210. This prevents the limiting block 121 from moving along the inner wall of the adjusting part 210 and entering the center of the curved structure 220, which would cause interference between the limiting block 121 and the adjusting part 210 and affect the movement of the moving part 200.

[0052] In some embodiments, see Figure 6 As shown, the movable member 200 is rotatably connected to the connecting portion 120, and the interior of the supporting member 300 defines a receiving cavity 320. The receiving cavity 320 is connected to a mounting opening 322 formed on the side of the supporting member 300 facing the movable member 200. The mounting opening 322 is used to accommodate a portion of the movable member 200. A mounting portion 230 is formed extending along a first direction on the side of the movable member 200 facing the connecting portion 120. The mounting portion 230 is provided at the mounting opening 322 so that the supporting member 300 and the movable member 200 are connected and fixed.

[0053] Specifically, in this embodiment, the connecting portion 120 is disposed in the receiving cavity 320 of the supporting member 300. The mounting portion 230 and the adjusting portion 210 are both disposed along a first direction from the side of the movable member 200 facing the connecting portion 120. The mounting portion 230 surrounds the adjusting portion 210. When the mounting portion 230 is installed at the mounting opening 322 of the supporting member 300, the adjusting portion 210 also connects and cooperates with the limiting block 121 of the connecting portion 120, causing the movable member 200 to drive the supporting member 300 to move along a second direction via the adjusting portion 210. By positioning the mounting part 230 around the adjusting part 210, not only can the contact area between the movable part 200 and the supporting part 300 be increased to improve the connection strength between them, but the inner wall at the mounting opening 322 can also limit the mounting part 230, ensuring that the adjusting part 210 does not deviate from the preset path when it rotates relative to the connecting part 120, such as preventing eccentric rotation of the adjusting part 210 during rotation.

[0054] Furthermore, in some embodiments, see [reference] Figure 3 and Figure 5 As shown, a recessed groove 340 is formed in the inner wall of the abutment member 300. The groove 340 is disposed around the inner wall of the abutment member 300, such that the groove 340 is circumferentially disposed on the inner wall of the abutment member 300. A protrusion 231 is formed on the outer wall of the mounting portion 230 protruding towards the inner wall of the abutment member 300. In this embodiment, the protrusion 231 is disposed around the outer wall of the mounting portion 230, and the protrusion 231 is circumferentially disposed on the outer wall of the mounting portion 230. In other embodiments, the protrusion 231 can be formed by separate protrusions, and the number can be one, two, or more. Specifically, after the mounting portion 230 is disposed at the mounting opening 322 to connect and fix the abutment member 300 and the movable member 200, the outer wall of the mounting portion 230 will contact the inner wall of the receiving cavity 320 of the abutment member 300. At this time, by providing a groove 340 on the inner wall of the abutment 300 and a protrusion 231 on the outer wall of the mounting portion 230, and connecting the protrusion 231 to the groove 340, the connection stability between the mounting portion 230 and the abutment 300 can be enhanced, preventing the movable member 200 from separating from the abutment 300 in the receiving cavity 320. Furthermore, in this embodiment, there is a gap between the protrusion 231 and the inner wall of the abutment 300. Since the movable member 200 also rotates relative to the abutment 300 when it moves in the second direction, the protrusion 231 and the groove can also reduce the friction between the outer wall of the mounting portion 230 and the inner wall of the abutment 300, improving the rotation efficiency of the movable member 200, thereby enhancing the adjustment efficiency of the braking device 10.

[0055] In other embodiments, a recessed groove 340 may be formed on the outer wall of the mounting portion 230, so that the groove 340 is circumferentially disposed on the outer wall of the mounting portion 230. The interior of the abutment member 300 protrudes towards the outer wall of the mounting portion 230 to form a protrusion 231, so that the protrusion 231 of the abutment member 300 is installed in the groove 340 of the mounting portion 230, thereby enhancing the connection stability between the mounting portion 230 and the abutment member 300, improving the rotation efficiency of the movable member 200, and enhancing the adjustment efficiency of the braking device 10.

[0056] In some embodiments, see Figures 2 to 4 As shown, the abutment includes a blocking portion 350. The blocking portion 350 is disposed on the side of the abutment 300 opposite to the movable member 200. The abutment portion 310 is formed by extending the blocking portion 350 along a first direction. The abutment portion 310 is located below the blocking portion 350. The abutment device 10 also includes a buffer member 400 connected to the blocking portion 350. Specifically, when the abutment device 10 is used to prevent the door from opening, the abutment portion 310 is located below the door to abut against the door. One side of the blocking portion 350 faces the door, and the buffer member 400 is connected to the side of the blocking portion 350 facing the door. The buffer member 400 abuts against the surface of the door. When external personnel are unable to open the door and attempt to impact or shake it, the buffer 400 absorbs the vibration energy transmitted to the blocking device 10 upon impact, preventing the blocking device 10 from becoming loose during impact and thus improving its blocking effect. Furthermore, the abutment portion 310 has multiple protrusions on the side that abuts against the door, making the surface of the abutment portion 310 that contacts the bottom of the door rough. This increases the friction between the abutment portion 310 and the bottom of the door, further enhancing the blocking effect of the blocking device 10.

[0057] In some embodiments, see Figure 2 and Figure 3 As shown, the blocking device 10 also includes an anti-slip element 500, which is connected to the side of the base 110 opposite to the connecting portion 120 along the second direction, i.e., the anti-slip element 500 is connected to the side of the base 110 that is in contact with the ground. When the blocking device 10 is used to prevent the door from opening, the anti-slip element 500 contacts the ground to increase the friction between the base 110 and the ground, reducing the possibility of the blocking device 10 moving when the door is pushed. Furthermore, since the blocking device 10 applies a downward force to the ground during use, the anti-slip element 500 can reduce the damage of the base 110 to the ground, preventing the ground from being scratched.

[0058] In this embodiment, the anti-slip component 500 is made of rubber or silicone or other adhesive materials. In other embodiments, the anti-slip component 500 may also be made of plastic, glass, or other anti-slip materials such as ceramic particles.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
