Description

Technical Field

[0001] The present application belongs to the technical field of door accessory components, and specifically relates to a door stopper. Background Art

[0002] A door stopper is a device used to limit the rotation angle of a door panel. Most existing door stoppers prevent the door panel from continuing to rotate by inserting into the gap between the door panel and the ground and getting stuck in the gap. When the user does not need to stop the door, the door stopper needs to be removed, and the door stopper needs to be replaced the next time it is used. This makes it inconvenient to use, and it is difficult to keep the placement of the door stopper consistent each time, making it difficult to ensure the consistency of the limiting angle of the door panel on each time. As a result, it may be impossible to limit the rotation angle of the door panel to an angle less than the normally open angle, which can easily lead to the door panel being unable to close automatically, and it is difficult to meet the requirements for the high opening and closing angles of the door panels in unmanned shops.

[0003] Therefore, the existing door stopper is inconvenient to use and may have the defect of being unable to limit the rotation angle of the door panel to an angle smaller than the normally open angle. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a door stopper that can solve the problem that the door stopper in the related art is inconvenient to use and may not be able to limit the rotation angle of the door panel to an angle less than the normally open angle.

[0005] The embodiment of the present application provides a door stopper, comprising:

[0006] A base, used for connection with a basic mounting surface;

[0007] A rotating member is rotatably connected to the base, and the rotating member can rotate between a first position and a second position. When the rotating member is in the first position, the rotating member can contact the door panel so that the maximum opening angle of the door panel is less than the normally open angle of the door panel. When the rotating member is in the second position, the rotating member is away from the door panel so that the maximum opening angle of the door panel is greater than or equal to the normally open angle.

[0008] In an embodiment of the present application, the base is connected to the base mounting surface, so that the door stopper can be installed on the base mounting surface, and when it is necessary to limit the opening angle of the door panel, the rotating member can be rotated to a first position, at which time the rotating member can contact the door panel and make the maximum opening angle of the door panel less than the normally open angle of the door panel, thereby allowing the door panel to automatically rebound to a closed state; when it is not necessary to limit the opening angle of the door panel, the rotating member can be rotated to a second position, at which time the rotating member is away from the door panel, so that the maximum opening angle of the door panel can be greater than or equal to the normally open angle, thereby allowing the door panel to be locked at the normally open angle, keeping the door in a normally open state. This arrangement does not require the door stopper to be disassembled when it is not necessary to limit the door panel, making it easy to use. Moreover, when the rotating member is in the first position, the rotating member limits the door panel at the same angle each time, thereby limiting the rotation angle of the door panel to an angle less than the normally open angle, thereby ensuring that the door panel can automatically rebound to a closed state each time it is opened, thereby meeting the requirements for the opening and closing angles of the door panels in unmanned shops.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] The door stopper provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] refer to Figures 1-11 The present invention provides a door stopper, which may include a base 100 and a rotating member 200. The base 100 may be connected to a base mounting surface, which may be a ground surface or a wall. The rotating member 200 may be rotatably connected to the base 100 and may rotate between a first position and a second position.

[0031] When the rotating member 200 is in the first position, the rotating member 200 can contact the door panel 500, so that the maximum opening angle of the door panel 500 is smaller than the normally open angle of the door panel 500. In this way, due to the restriction of the rotating member 200, the door panel 500 cannot be opened to the normally open angle, and the door panel 500 can automatically rebound to the closed state each time it is opened.

[0032] When the rotating member 200 is in the second position, the rotating member 200 is away from the door panel 500, so that the maximum opening angle of the door panel 500 is greater than or equal to the normally open angle. Thus, since the rotating member 200 is away from the door panel 500, it no longer restricts the door panel 500, allowing the door panel 500 to open to the normally open angle. Furthermore, the door panel 500 can be locked at the normally open angle and will not automatically rebound to the closed position.

[0033] It should be noted that the normally open angle of the door panel 500 may be the angle at which the door panel 500 is opened when in the normally open position. Here, the normally open angle of the door panel 500 may be 90°. The door panel 500 may be automatically closed by a floor spring or a door closer. Specifically, when the opening angle of the door panel 500 is greater than or equal to 90°, the door panel 500 is automatically locked at 90° and does not rebound to close. When the opening angle of the door panel 500 is less than 90°, the door panel 500 automatically rebounds to the closed position.

[0034] In this way, the door stopper can be installed on the base mounting surface by connecting the base 100 to the base mounting surface, and when it is necessary to limit the opening angle of the door panel 500, the rotating part 200 can be rotated to the first position. At this time, the rotating part 200 can contact the door panel 500, and make the maximum opening angle of the door panel 500 less than the normally open angle of the door panel 500, so that the door panel 500 can automatically rebound to the closed state; when there is no need to limit the opening angle of the door panel 500, the rotating part 200 can be rotated to the second position. At this time, the rotating part 200 is away from the door panel 500, so that the maximum opening angle of the door panel 500 can be greater than or equal to the normally open angle, so that the door panel 500 can be locked at the normally open angle, so that the door is in a normally open state. With this arrangement, when there is no need to limit the door panel 500, there is no need to disassemble the door stopper, which is easy to use. Moreover, when the rotating member 200 is in the first position, the rotating member 200 limits the door panel 500 at the same angle each time, so as to limit the rotation angle of the door panel 500 to an angle smaller than the normally open angle, thereby ensuring that the door panel 500 can automatically rebound to the closed state each time it is opened, thereby meeting the scenario where the opening and closing angles of the door panel 500 in unmanned shops are required to be higher.

[0035] In an optional embodiment, the rotating member 200 can be rotatably connected to the base 100 via a rotating shaft 300. Specifically, the base 100 can be provided with a first mounting hole 121, and the rotating member 200 can be provided with a second mounting hole 211. The first mounting hole 121 and the second mounting hole 211 are arranged opposite each other. The rotating shaft 300 can pass through the first mounting hole 121 and the second mounting hole 211, and the rotating shaft 300 can respectively have a clearance fit with the first mounting hole 121 and the second mounting hole 211. In order to prevent the rotating shaft 300 from falling out of the first mounting hole 121 and the second mounting hole 211, anti-slip portions 310 can be provided at both ends of the rotating shaft 300, and the diameters of the two anti-slip portions 310 are both larger than the apertures of the first mounting hole 121 and the second mounting hole 211. Optionally, gaskets can be provided between the two anti-slip parts 310 and the base 100 and the rotating part 200. In this way, pressure concentration between the anti-slip parts 310 and the base 100 and between the anti-slip parts 310 and the rotating part 200 can be avoided to protect the base 100 and the rotating part 200 from being worn by the anti-slip parts 310.

[0036] In an optional embodiment of the present application, a first locking hole 140 and a second locking hole 150 may be provided on the base 100 , and a third locking hole 230 may be provided on the rotating member 200 .

[0037] When the rotating member 200 is located at the first position, the third locking hole 230 may be opposite to the first locking hole 140 , and the third locking hole 230 and the first locking hole 140 may be connected by a fixing member to lock the rotating member 200 at the first position.

[0038] When the rotating member 200 is located at the second position, the third locking hole 230 may be opposite to the second locking hole 150 , and the third locking hole 230 and the second locking hole 150 may be connected by a fixing member to lock the rotating member 200 at the second position.

[0039] This arrangement can not only lock the rotating member 200 at a desired position, but also prevent others from rotating the rotating member 200.

[0040] In other embodiments, the first locking hole 140 and the second locking hole 150 may not be provided on the base 100, and the third locking hole 230 may not be provided on the rotating member 200. Specifically, the rotating member 200 and the base 100 can be relatively fixed through a damping member so that the rotating member 200 is locked in the desired position.

[0041] In an optional embodiment, the fixing member may be a lock 400. When the rotating member 200 is in the first position, the locking beam 410 of the lock 400 may pass through the third locking hole 230 and the first locking hole 140 to connect the third locking hole 230 and the first locking hole 140, thereby locking the base 100 and the rotating member 200. When the rotating member 200 is in the second position, the locking beam 410 of the lock 400 may pass through the third locking hole 230 and the second locking hole 150 to connect the third locking hole 230 and the second locking hole 150, thereby locking the base 100 and the rotating member 200. In this way, the rotating member 200 can be prevented from being rotated by others and can also play a certain role in preventing it from being lost.

[0042] Of course, the fixing member can also be a fixing nail, a fixing rod, a rope, a wire, etc.

[0043] It should be noted that the fixing part can be selected and configured by the user, and the fixing part can also be a part of the door stopper. For example, the fixing part includes a first plug rod and a second plug rod that are telescopically arranged on the base 100. When the rotating part 200 is in the first position, the first plug rod can be extended and passed through the first lock hole 140 and inserted into the third lock hole 230; when the rotating part 200 is in the second position, the second plug rod can be extended and passed through the second lock hole 150 and inserted into the third lock hole 230.

[0044] In an optional embodiment of the present application, a limiter 130 may be provided on the base 100, and the rotatable member 200 may cooperate with the limiter 130 to limit the position of the rotatable member 200 in the direction from the rotatable member 200 to the base mounting surface. In this way, the limiter 130 can limit the rotatable member 200, preventing the rotatable member 200 from continuing to rotate toward the base mounting surface after rotating to the first position, thereby preventing the rotatable member 200 from failing to restrain the door panel 500.

[0045] In other embodiments, the limiting portion 130 may not be provided on the base 100 .

[0046] In an optional embodiment, the base 100 may be provided with at least two limiting portions 130, which may include a first limiting portion 131 and a second limiting portion 132. Figure 2 As shown, the first limiting portion 131 and the second limiting portion 132 can be respectively disposed on two opposite sides of the base 100 .

[0047] When the door panel 500 is opened toward the first direction, the rotating member 200 can be positioned and engaged with the first limiting portion 131 .

[0048] When the door panel 500 is opened in a direction opposite to the first direction, the rotating member 200 can be engaged with the second limiting portion 132 in a limiting manner.

[0049] In this way, the door stopper can be adapted to door panels 500 with different opening directions.

[0050] In other embodiments, only one limiting portion 130 may be provided on the base 100 , and the rotating member 200 can only limit the door panel 500 in one direction.

[0051] Optionally, the rotating member 200 may be provided with at least two third locking holes 230 , which may include a first connecting hole 231 and a second connecting hole 232 . The first connecting hole 231 and the second connecting hole 232 may be symmetrical about the rotation axis of the rotating member 200 .

[0052] When the door panel 500 is opened in the first direction, the rotating member 200 can be limited and matched with the first limiting portion 131 when it is rotated to the first position, and the first connecting hole 231 can be opposite to the first lock hole 140; when the door panel 500 is opened in the opposite direction to the first direction, the rotating member 200 can be limited and matched with the second limiting portion 132 when it is rotated to the first position, and the second connecting hole 232 can be opposite to the first lock hole 140.

[0053] Specifically, when the door panel 500 opens to the right, the rotating member 200 can be rotated to the left, and the first connecting hole 231 is opposite to the first lock hole 140, and the lock beam 410 of the lock 400 can pass through the first connecting hole 231 and the first lock hole 140 to lock the rotating member 200 and the base 100; when the door panel 500 opens to the left, the rotating member 200 can be rotated to the right, and the second connecting hole 232 is opposite to the first lock hole 140, and the lock beam 410 of the lock 400 can pass through the second connecting hole 232 and the first lock hole 140 to lock the rotating member 200 and the base 100.

[0054] Further optionally, a fourth lock hole 160 may be provided on the base 100, the second lock hole 150 and the fourth lock hole 160 may be symmetrical about the rotation axis of the rotating member 200, and when the rotating member 200 is in the second position, the first connecting hole 231 may be opposite to the second lock hole 150, and the first connecting hole 231 and the second lock hole 150 may be connected by a first fixing member, the second connecting hole 232 may be opposite to the fourth lock hole 160, and the second connecting hole 232 and the fourth lock hole 160 may be connected by a second fixing member, so that the locking effect of the base 100 and the rotating member 200 can be improved.

[0055] In an optional embodiment of the present application, the rotating member 200 may include a rotating connection portion 210 and a door panel contact portion 220. The rotating connection portion 210 may be rotatably connected to the base 100, and the door panel contact portion 220 may be connected to an end of the rotating connection portion 210 away from the base 100, and in the extension direction of the rotation axis of the rotating member 200, the size of the door panel contact portion 220 may be larger than the size of the rotating connection portion 210. Specifically, the width of the door panel contact portion 220 in the extension direction of the rotation axis of the rotating member 200 may be larger than the thickness of the rotating connection portion 210 in the extension direction of the rotation axis of the rotating member 200. In this way, the contact area between the rotating member 200 and the door panel 500 can be increased through the door panel contact portion 220, and the stress between the rotating member 200 and the door panel 500 can be reduced, thereby avoiding mutual wear between the rotating member 200 and the door panel 500 or reducing the degree of wear between the rotating member 200 and the door panel 500.

[0056] In other embodiments, the rotating member 200 may also include only the rotating connection portion 210 . When the rotating member 200 is located at the first position, the end of the rotating connection portion 210 away from the base 100 may contact the door panel 500 .

[0057] In an alternative embodiment, the door panel contact portion 220 may include a door panel restraining portion 221. The door panel restraining portion 221 may be connected to the end of the rotating connection portion 210 away from the base 100. The surface of the door panel restraining portion 221 facing away from the rotating connection portion 210 may be a curved surface, and the curved surface may protrude away from the rotating connection portion 210. This prevents the end of the door panel restraining portion 221 from scratching the door panel 500 when it contacts the rotating member 200. Of course, the surface of the door panel restraining portion 221 facing away from the rotating connection portion 210 does not need to be a curved surface.

[0058] Here, the door panel restriction portion 221 and the rotation connection portion 210 may be an integrated structure. Specifically, the rotating member 200 may be a sheet metal bending member.

[0059] The door panel contact portion 220 may further include a buffer member 222. The buffer member 222 may be disposed on the side of the door panel restricting portion 221 facing away from the rotating connection portion 210 and may be configured to contact the door panel 500. Thus, the buffer member 222 provides a cushioning effect on the door panel 500, thereby preventing a hard collision between the door panel 500 and the rotating member 200. The buffer member 222 may be foam or rubber, but may also be made of other elastic materials.

[0060] Of course, the door panel contact portion 220 may not include the buffer member 222 .

[0061] In an optional embodiment, when the rotating member 200 is in the first position, the distance between the door panel contact portion 220 and the base mounting surface can be greater than or equal to the distance between the door panel 500 and the base mounting surface. In this way, when the rotating member 200 is in the first position, the door panel contact portion 220 can fully contact the door panel 500 to ensure the door blocking effect of the rotating member 200. In addition, the force on the door panel contact portion 220 can be balanced, avoiding deformation of the door panel contact portion 220 or reducing the degree of deformation of the door panel contact portion 220, thereby facilitating the extension of the service life of the door panel contact portion 220. Of course, when the rotating member 200 is in the first position, the distance between the door panel contact portion 220 and the base mounting surface can also be less than the distance between the door panel 500 and the base mounting surface, but a portion of the door panel contact portion 220 can still contact the door panel 500.

[0062] Optionally, the distance H1 between the end of the limiting portion 130 away from the base installation surface and the base installation surface may be greater than or equal to the distance between the door panel 500 and the base installation surface, and, as Figure 7 As shown, when the rotating member 200 is in the first position, the distance H2 between the door panel contact portion 220 and the base installation surface can be greater than or equal to the distance H1 between the end of the limiting portion 130 away from the base installation surface and the base installation surface.

[0063] In this embodiment, the distance H1 between the end of the limiting portion 130 away from the basic installation surface and the basic installation surface may be greater than or equal to 10 mm, and the distance between the door panel 500 and the basic installation surface may be less than or equal to 10 mm.

[0064] In an optional embodiment of the present application, the base 100 may include a fixing plate 110 and a connecting plate 120. The fixing plate 110 may be used to abut and connect with the base installation surface, and the connecting plate 120 may be connected to the fixing plate 110. The connecting plate 120 may be located on a side of the fixing plate 110 facing away from the base installation surface, and the rotating member 200 may be rotatably connected to the connecting plate 120. In this way, by affixing the fixing plate 110 to the base installation surface, the contact area between the base 100 and the base installation surface may be increased, and the stability of the fixing of the base 100 may be improved.

[0065] Of course, the base 100 may also only include the connecting plate 120 , and the connecting plate 120 may be directly connected to the basic installation surface.

[0066] Optionally, the fixing plate 110 can be connected to the base mounting surface via fixing nails. This allows the base 100 to be securely mounted on the base mounting surface, preventing movement even when the door blocker is subjected to significant force, and also preventing it from being removed by humans. Specifically, the fixing plate 110 can be provided with through-holes 111 for the fixing nails to pass through. The nail rods of the fixing nails can pass through through-holes 111 and extend into the base mounting surface. The diameter of the fixing nail heads can be larger than the diameter of through-holes 111, thereby securing the fixing plate 110 to the base mounting surface.

[0067] Furthermore, the fixing plate 110 may be connected to the base installation surface via a plurality of fixing nails to improve the connection strength between the fixing plate 110 and the base installation surface.

[0068] Here, the fixing nail can be an expansion nail.

[0069] In an alternative embodiment, the connecting plate 120 is foldably connected to the fixing plate 110 , and the connecting plate 120 is rotatable between a folded position and an unfolded position.

[0070] Among them, when the connecting plate 120 is in the folded position, the connecting plate 120 can be fitted with the fixed plate 110, so that the rotating part 200 can rotate toward the fixed plate 110 together with the connecting plate 120, so that the rotating part 200 is close to the base installation surface, and then when there is no need to use the door stopper to limit the door panel 500, the door stopper can be prevented from tripping pedestrians.

[0071] When the connecting plate 120 is in the extended position, the plane of the connecting plate 120 and the plane of the fixed plate 110 may intersect. Specifically, the plane of the connecting plate 120 and the plane of the fixed plate 110 may be perpendicular to each other, so that the rotating member 200 can contact the door panel 500. In this way, when the connecting plate 120 is in the extended position, the rotating member 200 can be away from the base mounting surface, so that the door stopper can continue to limit the door panel 500.

[0072] Optionally, the connecting plate 120 and the fixing plate 110 may be connected by a hinge, or other methods may be used to achieve a folding connection.

[0073] Of course, the connecting plate 120 and the fixing plate 110 may also be connected without being folded. Specifically, the connecting plate 120 and the fixing plate 110 may be an integrated structure. Here, the base 100 may be a sheet metal bending part.

[0074] In the embodiment of the present application, the door panel 500 can be mounted on a door frame of a mounting base 600. Optionally, the mounting base 600 can be a wall. When the rotating member 200 of the door stopper rotates 180°, the rotating member 200 rotates to the first position. At this point, the door panel 500 can contact the rotating member 200 after opening. In other words, the door panel 500 is blocked by the rotating member 200, preventing the door panel 500 from opening to 90°. At this point, the door panel 500 can be automatically closed by releasing the rotating member 200.

[0075] When the rotating member 200 rotates to 90°, or the rotating member 200 rotates less than 90°, that is, when the rotating member 200 is in the second position or when the rotating member 200 exceeds the second position, when the door panel 500 is opened to 90°, the door panel 500 does not contact the rotating member 200. At this time, the door panel 500 is released and the door panel 500 can be stopped at the normally open position of 90°. Here, when the rotating member 200 is in the 0° position, the rotating member 200 can block the door panel 500 in the opposite direction of opening.

[0076] For example, in a shop, during the day, when someone is on duty, the door panel 500 needs to be in a normally open state. At this time, the door panel needs to be opened to the normally open angle (i.e. 90°) and locked at the normally open angle by a floor spring or a door closer. At this time, the rotating member 200 of the door stopper can be locked at 90° so that the opening angle of the door panel 500 can be greater than or equal to the normally open angle. Of course, if Figure 10 and Figure 11 As shown, the rotating member 200 can also be locked at 0°.

[0077] At night, when the store is unattended, the door panel 500 needs to be able to close automatically after opening. In order to ensure that the door panel 500 can close automatically every time a customer enters the door, it is necessary to ensure that the opening angle of the door panel 500 is smaller than the normal opening angle. Figure 8 and Figure 9 As shown, by locking the rotating member 200 of the door stopper in the first position, that is, the rotating member 200 can be locked at 180°, the rotating member 200 can limit the door panel 500 to limit the opening angle of the door panel 500 to be less than the normally open angle.

[0078] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
