Description

Technical Field

[0001] The present invention relates to the field of safety protection technology, and in particular to a door stopper. Background Art

[0002] In daily life, doors may be blown shut by the wind or opened or closed by children or pets playing in or out, which may cause accidents such as pinching or injuring children's hands when the door is closed.

[0003] Existing child safety doorstops come in various styles, including clamping, hooking, and wedge-shaped. However, none of these are fixed and lack an on / off function. Users must manually remove these doorstops each time they close the door, making them inconvenient. Furthermore, these non-fixed doorstops are prone to being misplaced and lost. For example, a doorstop disclosed in Chinese Patent CN201120159595.7 and a door stopper disclosed in Chinese Patent CN201921571844.6 both suffer from these issues. Summary of the Invention

[0013] When the slide moves to the first working position, the through slot is misaligned with the limiting protrusion, and the side wall of the slide abuts against the limiting protrusion, thereby limiting the movement of the door stop body between the first position and the second position;

[0014] When the slide moves to the second working position, the through slot and the limiting protrusion are not misaligned, and the slide slides on the limiting protrusion to achieve movement of the door stop body between the first position and the second position;

[0015] When the door stop body is in the first position, the door stop body is not on the movement track of the door closing; when the door stop body is in the second position, the door stop body is on the movement track of the door closing.

[0016] Preferably, the door stop body is provided with a second locking device, and the second locking device comprises:

[0017] A locking piece is slidably arranged in the door stop body, and the locking piece has a push button and a locking protrusion. The push button extends out of the door stop body through the second opening of the door stop body, and the locking protrusion is movably inserted into the through groove to limit the movement of the slide from the first working position to the second working position.

[0018] Preferably, the first locking device further comprises:

[0019] The second elastic member has two ends respectively abutting against the sliding seat and the door stop body, so as to make the sliding seat have a tendency to move to the first working position.

[0020] Preferably, the rear end side wall of the through slot has a guide surface;

[0021] When the door stop body moves from the second position to the first position, the guide surface is used to guide the sliding seat to slide on the limiting protrusion.

[0022] Preferably, the sliding seat has an abutment portion, the abutment portion is located at the edge of the slot, and the abutment portion movably abuts against the limiting protrusion.

[0023] Preferably, the limiting protrusion has a connecting column and a protrusion, the connecting column is slidably placed in the through hole, and the upper end of the connecting column is movably connected to the elastic member 1, the protrusion is located at the side end of the connecting column, and the protrusion movably abuts the side wall of the sliding seat.

[0031] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0032] 1. The door stop body designed in this technical solution can slide on the mounting base. After the door is opened, the door stop body moves to the closing track of the door and the door frame, so that a gap is maintained between the door and the door frame to prevent fingers from being pinched, thereby avoiding safety issues such as children's fingers being pinched or being locked in the room. Moreover, there is no need to remove the door stop when closing the door. It only needs to be moved to the first position, which is convenient to use.

[0033] 2. This technical solution designs the through groove of the slide to be misaligned with the limiting protrusion, so that the limiting protrusion abuts the slide to limit the movement of the door stop body on the mounting seat. The door stop body can be moved between the first position and the second position by pressing the slide, which is simple to operate and easy to use.

[0034] 3. This technical solution designs a second locking device to limit the movement of the slide, so that the slide remains in the first working position. When the door stop body is in the second position, even if a child presses the slide while playing, the slide will not move, ensuring that the side wall of the slide abuts against the limiting protrusion, preventing the door stop body from moving to the first position, ensuring the safety of the door stop body when in use, and preventing the door stop body from leaving the closing trajectory of the door when children play.

[0050] The specific implementation of this technical solution is further described in detail below with reference to the accompanying drawings. Figures 1-8 .

[0051] A door stopper, comprising: a mounting base 1, a door stopper body 2, an elastic member 3, a first locking device 6, and a second locking device 7;

[0052] The mounting base 1 is used to be installed on a door or door frame. The bottom of the mounting base 1 is installed on the edge of the door or door frame by gluing, sucking cups, or embedding blocks and grooves. A limiting protrusion 11 is provided on the mounting base 1.

[0053] The door stop body 2 is slidably connected to the mounting base 1 and can move between a first position and a second position. When the door stop body 2 is in the first position, the front end of the door stop body 2 retracts to the edge of the door or door frame, so that the door stop body 2 is not located on the movement trajectory of the door closing, and the door can be closed or opened normally. When the door stop body 2 is in the second position, the front end of the door stop body 2 extends out of the edge of the door or door frame, so that the door stop body 2 is located on the movement trajectory of the door closing, thereby preventing the door from closing accidentally and pinching children's hands, thereby improving safety.

[0054] A through hole 41 is formed at the lower end of the door stop body 2 . The through hole 41 is a strip-shaped hole. The limiting protrusion 11 is placed in the door stop body 2 through the through hole 41 , and the limiting protrusion 11 can move in the through hole 41 .

[0055] The elastic member 1 3 is a tension spring, a rubber band or a rubber ring, and its two ends are movably connected to the mounting base 1 and the door stop body 2, respectively, so as to make the door stop body 2 have a tendency to move toward the second position. The elastic member 1 3 enables the door stop body 2 to move forward on the mounting base 1, so that the front end of the door stop body 2 can be placed on the closing trajectory of the door.

[0056] The first locking device 6 is installed in the door stop body 2 and is used to limit the movement of the door stop body 2 on the mounting base 1;

[0057] The first locking device 6 comprises: a sliding seat 61 and a second elastic member 62;

[0058] The slide 61 is slidably disposed in the door stop body 2 and is provided with a through slot 63. The slide 61 can move between a first working position and a second working position. The slide 61 has a pressing portion 64. The pressing portion 64 extends out of the door stop body 2 through the opening 21 of the door stop body 2.

[0059] The second elastic member 62 is a spring or a disc spring, with its two ends respectively contacting the slide 61 and the door stop body 2, and is used to make the slide 61 tend to move to the first working position. When an external force presses the slide 61 to the second working position, the slide 61 is released and the slide 61 is able to return to the first working position under the action of the second elastic member 62.

[0060] A first fixing groove is provided on the side end of the slide seat 61 , a second fixing groove is provided on the inner side wall of the door stop body 2 , and both ends of the second elastic member 62 are respectively placed in the first fixing groove or the second fixing groove.

[0061] When the slide 61 moves to the first working position, the through slot 63 is misaligned with the limiting protrusion 11, and the side wall of the slide 61 (i.e., the notch edge of the through slot 63) abuts against the limiting protrusion 11, so that the slide 61 is blocked by the limiting protrusion 11, thereby limiting the movement of the door stop body 2 between the first position and the second position; both the left and right side walls of the slide 61 can abut against the limiting protrusion 11, thereby limiting the movement of the slide 61 on the limiting protrusion 11; when the left side wall of the slide 61 abuts against the limiting protrusion 11, the door stop body 2 is limited to move from the first position to the second position; when the right side wall of the slide 61 abuts against the limiting protrusion 11, the door stop body 2 is limited to move from the second position to the first position;

[0062] When the slide 61 moves to the second working position, the through groove 63 and the limiting protrusion 11 are not misaligned, and the slide 61 slides on the limiting protrusion 11 (that is, the limiting protrusion 11 can slide in the through groove 63, so that the slide 61 can be located on the left or right side of the limiting protrusion 11), realizing the movement of the door stop body 2 between the first position and the second position, thereby realizing the switching of the door stop body 2 to the extended or retracted state.

[0063] The second locking device 7 is arranged in the door stop body 2, and the second locking device 7 includes:

[0064] When the lock body 7 is unlocked, the latch 72 is in the unlock state, and the latch 7 is in the unlock state, so that the lock body 7 can be unlocked, and the latch 7 is in the unlock state.

[0065] Combine Figure 2 、 Figure 4 and Figure 7 The present technical solution is to use the left side wall of the slide 61 to abut against the limiting protrusion 11, thereby limiting the movement of the door stop body 2 from the first position to the second position, and preventing the door stop body 2 from being in the second position under the action of the elastic member 1 3;

[0066] The rear end side wall of the through slot 63 has a guide surface 631, that is, the notch of the through slot 63 located on the right side of the slide 61, and the upper side wall of the notch is inclined toward the notch to form the guide surface 631, so that the rear half of the through slot 63 (i.e. Figure 7 and Figure 8 The diameter of the right half of the middle through slot 63 gradually increases from left to right. At this time, when the door stop body 2 moves to the second position, the limiting protrusion 11 of the present design solution can not slide out of the notch in the rear half of the through slot 63. The side end of the limiting protrusion 11 movably abuts against the guide surface 631, so that the limiting protrusion 11 does not affect the forward movement of the locking member 71 (of course, in practice, the limiting protrusion 11 can also slide out of the notch in the rear half of the through slot 63 and then slide into the through slot 63 through the guide surface 631);

[0067] When the door stop body 2 moves from the second position to the first position, the guide surface 631 is used to guide the slide 61 to slide on the limiting protrusion 11, that is, the limiting protrusion 11 slides on the guide surface 631 to the front half of the through groove 63 and slides out of the front end of the through groove 63 (in actual use, the limiting protrusion 11 is fixed on the door and is stationary, and it is the slide 61 with the through groove 63 that slides on the limiting protrusion 11).

[0068] The slide 61 has an abutment portion 65, which is located at the edge of the slot 63. The abutment portion 65 movably abuts the limiting protrusion 11. The abutment portion 65 reduces the wear of the slot edge of the slot 63 while ensuring the abutment area with the limiting protrusion 11 to limit the movement of the limiting protrusion 11.

[0069] The limiting protrusion 11 has a connecting column 12 and a protrusion 13. The connecting column 12 and the protrusion 13 are integrally formed on the mounting base 1. The lower end of the connecting column 12 can also be glued or threaded to the upper end of the mounting base 1. The connecting column 12 is slidably placed in the through hole 41, and the upper end of the connecting column 12 is movably connected to the elastic member 3. The protrusion 13 is located at the side end of the connecting column 12, and the protrusion 13 movably abuts the side wall of the slide 61.

[0070] An insertion hole 411 is provided at the rear end of the through hole 41. When the connecting column 12 and the protrusion 13 are integrally formed on the mounting base 1, the upper end of the connecting column 12 and the protrusion 13 are inserted into the door stop body 2 through the insertion hole 411, and the lower end of the connecting column 12 is slidably placed in the through hole 41.

[0071] A mounting groove 42 is provided at the lower end of the door stop body 2, and a through hole 41 is opened at the bottom of the mounting groove 42. The mounting seat 1 is slidably placed in the mounting groove 42. The surrounding side walls of the mounting groove 42 limit the sliding range of the mounting seat 1. The inner wall of the groove of the mounting groove 42 is provided with an anti-slip portion 43. The upper parts of both sides of the mounting seat 1 have sliders 14, and the anti-slip portion 43 movably abuts the lower end of the slider 14.

[0072] The door stop body 2 has a shell 1 4 and a shell 2 5. The shell 1 4 is provided with a slide groove 2 44 and a slide groove 3 45. The slide seat 61 is slidably placed in the slide groove 2 44, and the locking member 71 is slidably placed in the slide groove 3 45. Figure 5 The second slide groove 44 is vertically arranged to enable the slide 61 to slide up and down, and the third slide groove 45 is horizontally arranged to enable the locking member 71 to slide left and right.

[0073] A fixing post 46 is provided at the upper end of the shell 1 4 , and the fixing post 46 is located behind the insertion hole 411 . The fixing post 46 is connected to the rear end of the elastic member 1 3 . A fixing post 2 is provided on the shell 2 5 , and the interior of the fixing post 2 is hollow. When the shell 1 4 is installed on the shell 2 5 , the fixing post 46 is engaged with the fixing post 2.

[0074] The lower end of the shell 1 4 has a front side and left and right sides of the installation groove 42, and the left and right sides have anti-slip parts 43. The lower end of the shell 2 5 has a rear side and part of the left and right sides of the installation groove 42.

[0075] The door stop body 2 is provided with an anti-collision device 8, which includes:

[0076] A connecting member 81 having a card interface 82 formed thereon;

[0077] The anti-collision member 83 is a rubber or silicone member, which is sleeved on the connecting member 81. The anti-collision member 83 wraps the upper end and the peripheral side of the connecting member 81, and the edge of the anti-collision member 83 is located between the lower end of the edge of the connecting member 81 and the upper end of the door stop body 2;

[0078] When the connecting member 81 is installed on the door stop body 2, the lower edge of the connecting member 81 presses the edge of the anti-collision member 83 against the upper end of the door stop body 2;

[0079] A connecting shaft 51 is provided on the door stop body 2, and a clamping block 52 is provided on the outer side of the connecting shaft 51. An opening three 53 is opened on the connecting shaft 51, and the opening three 53 passes through the upper end of the connecting shaft 51.
