Description

Technical Field

[0001] The invention belongs to the field of furniture products, and in particular relates to a door stopper capable of bidirectionally locking a door leaf, and a method for bidirectionally locking a door leaf by using the door stopper. Background Art

[0002] A door stop is a device installed on a door leaf to contact the floor or ground, thereby temporarily locking the door leaf during opening or closing. Unlike a door stopper that is only fixed at the maximum open position, a door stop can lock the door leaf at any position, thereby preventing the door leaf from opening or closing. For example, in a home with pets or infants, a door stop can be used to fix a bedroom door leaf in a position where it is only opened a certain distance, thereby achieving ventilation or preventing fingers from being pinched when closing.

[0003] Existing door stops generally use wedges to act between the floor and the bottom end of the door leaf, or are supported obliquely on the ground (such as the floor) to achieve a one-way locking effect, so they usually only need to be fixed on the front and rear surfaces of the door leaf.

[0004] Therefore, it is necessary to develop a new door stop that is easy to install and use and can carry out bidirectional locking of the door leaf. Summary of the invention

[0005] The object of the present invention is to provide a door stop which is installed at one side of a door leaf and can realize bidirectional locking of the door leaf, and to provide a method for locking the door leaf using the door stop.

[0006] As a first aspect of the present invention, a two-way locking door stop is provided, which can be used to be fixed to a door leaf to lock it in both directions to prevent the door leaf from opening and closing; comprising:

[0007] The base is used to be fixed to the door leaf, and the base includes a base body and a telescopic member. The telescopic member is telescopically arranged relative to the base body. The base body is provided with a first surface for fitting to the surface of the door leaf, and the telescopic member is provided with a second surface for fitting to the bottom surface of the door leaf.

[0008] The lock body is rotatably pivoted on the base around a pivot axis, and the lock body is rotatably arranged between a first state and a second state. In the first state, the lock body is arranged downwardly parallel to the first surface.

[0009] And, a first locking assembly, the first locking assembly acts between the lock body and the base to lock or unlock both; the first locking assembly includes a first locking member and a second locking member.

[0010] According to the above-mentioned two-way locking door stop, the two-way locking door stop is fixed to the surface of the door leaf by gluing at the first surface, and is fixed to the bottom surface of the door leaf by gluing at the second surface.

[0011] According to the above-mentioned two-way locking door stop, the base body is fixed to the surface of the door leaf by screws so that the first surface abuts against the surface of the door leaf, and is fixed to the bottom surface of the door leaf by gluing at the second surface or the second surface abuts against the bottom surface of the door leaf.

[0012] According to the above-mentioned two-way locking door stop, when the two-way locking door stop is fixed by gluing on both surfaces, glue can be pre-set on at least one of the first surface and the second surface, and the user can directly use it by peeling off the backing paper when using it.

[0013] According to the above-mentioned two-way locking door stop, a positioning mechanism or a limiting mechanism is provided on the base, wherein the positioning mechanism is used to position the installation position of the telescopic part at a preset retraction distance, and the limiting mechanism is used to provide retraction distances of different values ​​for the user to adjust the installation position of the telescopic part before installation. Therefore, the former corresponds to a door stop with a fixed retraction distance d1, and the latter corresponds to a door stop with an adjustable retraction distance d1.

[0014] According to the above-mentioned two-way locking door stop, the lock body is pivotally connected to the base around a pivot at its upper end, and is formed as an abutment end at its lower end.

[0015] According to the above-mentioned two-way locking door stop, the abutment end is made of a soft material to be deformed under pressure in the first state, so that it can be squeezed and deformed to enhance the abutment force and the soft material can also increase the friction with the ground. Preferably, in the first state, the lock body is vertically arranged to fit the surface of the door leaf, so that the lock body is vertically arranged when the first locking operation is performed, which is very important for two-way locking, and the locking force in one direction will not be too small, and the distance that the lower end of the lock body protrudes from the surface of the door leaf is also the smallest, and it is easy to use.

[0016] According to the above-mentioned two-way locking door stop, the lock body includes a shell and a shell cover, the shell cover is made of soft rubber and is buckled at the end of the shell, the abutment end is formed on the shell cover, and a plurality of air cavities are arranged on the end surface of the shell cover. The air cavities can form negative pressure to increase contact force when squeezed and deformed, and can also increase the contact area with the ground after deformation to increase friction. The air cavity can preferably be composed of a hemispherical cavity recessed on the surface of the shell cover.

[0017] According to the above-mentioned two-way locking door stop, the lock body also includes a lock core installed in the lock shell, the lock core is provided with a lock tongue and a first button, the first side of the lock body is provided with a first side opening, the second side is provided with a concave hole, the first button is provided in the first side opening, and the lock tongue is provided at the concave hole. The first locking member includes a convex member convexly provided on one side of the base and a lock hole formed through or concavely on the convex member, the concave hole and the lock tongue constitute the second locking member; in the first state, the convex member is inserted into the concave hole so that the lock tongue extends into the lock hole to lock the rotation of the lock body, and the first button is used to unlock the lock body from the first state.

[0018] Among them, the lock hole can be through or not through (i.e., concavely set) with the convex part, and the penetration direction is preferably set along the axial direction of the lock body. The lock tongue can be inserted into the lock hole after the convex part extends into the concave hole, so that the lock body is firmly locked on the base and is not easily pulled open by force.

[0019] According to the above-mentioned two-way locking door stop, a second side opening is also provided on the second side of the lock shell, a second button is provided on the lock core, the second button is arranged in the second side opening, and the second button is used to unlock the lock body from the second state, thereby allowing the lock body to rotate to the first state.

[0020] According to the above-mentioned two-way locking door stop, the lock core is movably arranged in the lock body along the axial displacement, that is, it is arranged along the axial direction of the lock body (that is, its length direction), so that the first button and / or the second button can be moved along the axial displacement of the lock body to unlock.

[0021] Preferably, the base further comprises a pivot seat protruding from one side of the base body, and the lock body is pivotally connected to the pivot seat, for example, by adopting a pin-through arrangement.

[0022] Preferably, the lock body is also provided with a lock column driven by the lock core, the lock shell is provided with a lock hole, the lock column is telescopically arranged in the lock hole and is unlocked by the displacement movement driven by the lock core, and a first through hole is provided on the pivot seat. In the second state, the lock column can be inserted into the first through hole to lock and maintain the lock body.

[0023] Preferably, the lock body is further provided with a lock column driven by the lock core, the lock column is arranged in a lock hole located below the arm shaft hole and is driven by the lock core to move and unlock, and a first through hole is also provided above the first pivot hole.

[0024] As a second aspect of the present invention, a method for bidirectionally locking a door leaf is also provided, comprising:

[0025] A door stop is provided, which has any of the above-mentioned door stop structures, that is, adopts the above-mentioned door stop.

[0026] Fix the door stop to the door leaf, and ensure that the length of the working section of the lock body is greater than the distance from the pivot to the ground. The length of the working section of the lock body refers to the distance from the end of the lock body to the pivot in the natural state;

[0027] Operate the door leaf and the door stop to lock the door leaf in both directions. When the door leaf is in the position to be locked, rotate the lock body until its end contacts the bottom surface, and then push the door leaf toward the door stop to make the lock body fit with the base, so that the first locking member engages with the second locking member to lock the rotation of the lock body.

[0028] According to the above method, when the door stop is fixed to the door leaf, the door stop is first fitted to the door leaf after the lock body is rotated to the first state, the telescopic member is adjusted to be displaced upward by a predetermined distance relative to the ground, and then the lock body is rotated to the second state, the lower end of the telescopic member is positioned close to the ground and the base body is installed on the door leaf, and finally the telescopic member is moved up to fit the bottom end surface of the door leaf; or, the telescopic member of the door stop may have its maximum extension length preset or its extension value marked, that is, the position adjustment of the telescopic member is not adjusted with the door leaf and the ground as reference, but with the distance value between the door stop's own pivot and the end surface of the lock body as reference, to control the extension length of the telescopic member or mark the change in its value when it is extended and retracted relative to the fixed seat on the telescopic member, which is also feasible and more convenient.

[0029] According to the above method, when unlocking is required, the first button is driven to move to unlock the first locking assembly, and the lock body is rotated to the second state so that the lock body fits the surface of the door leaf, so that the door stop can be beautifully stored in the unlocked state.

[0030] The bidirectional locking door stop and door leaf locking method of the present invention has at least the following beneficial effects:

[0031] 1. Only one door stopper needs to be installed on one side of the door leaf to realize bidirectional locking of the door leaf, which solves the problem that the traditional door stopper can only be locked in one direction.

[0032] 2. The door stop has a compact structure and is easy to install and use. It can be stored close to the surface of the door leaf when not in use. It will not be damaged by knocks when opening and closing the door, and it is not easy to collide with the human body and injure people.

[0033] 3. When the door is in the locked state (i.e. the first state), the lock body basically acts vertically on the floor (i.e. substantially perpendicular to the ground), it occupies a small area and is not easy to trip people, and it has sufficient locking strength in both directions, and there will not be a situation where the force is obviously insufficient in one direction.

[0034] 4. It can be fixed to the surface and bottom end of the door leaf by gluing. Combined with its structural relationship and force direction, it can provide sufficient locking force for the door leaf when it is locked. In addition, the telescopic structure of the base can also adapt to the use of door leaves with different ground clearances. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The base 10 is used to be fixed to the door leaf. The base 10 includes a base body 11 and a telescopic member 12. The telescopic member 12 is telescopically movable relative to the base body 11. The base body 11 is provided with a first surface 101 for fitting to the surface of the door leaf, and the telescopic member 12 is provided with a second surface 102 for fitting to the bottom surface of the door leaf.

[0058] A lock body 20, the lock body 20 is rotatably pivoted to the base 10 around a pivot 100, the lock body 20 is rotatably arranged between a first state and a second state, and in the first state, the lock body 20 is arranged downwardly parallel to the first surface 101. And,

[0059] The first locking assembly acts between the lock body 20 and the base 10 to lock or unlock the two. The first locking assembly includes a first locking member 14 and a second locking member 15 .

[0060] Preferably, the door stop is provided with adhesive on both the first surface 101 and the second surface 102 for adhesive fixation.

[0061] Preferably, the lock body 20 is made of a soft material, such as soft rubber, and contacts the ground to enhance the force.

[0062] Preferably, the lock body is provided with a first and a second button on both sides respectively, and also has a second locking component in the second state. Pressing the two buttons can simultaneously drive the first locking component and the second locking component to unlock, so as to achieve locking retention in the first state and storage retention in the second state.

[0063] A method for bidirectionally locking a door leaf, comprising:

[0064] A door stop is provided, which has the above-mentioned door stop structure, in other words, a door stop adopting any of the above-mentioned structures.

[0065] The door stop is fixed to the door leaf, and when fixing, ensure that the length of the working section of the lock body 20 is greater than the distance from the pivot 100 to the ground. The length of the working section of the lock body 20 refers to the distance from the end of the lock body 20 to the pivot 100 in the natural state.

[0066] Operate the door leaf and the door stop to lock the door leaf in both directions. When the door leaf is in the position to be locked, rotate the lock body 20 until its end contacts the bottom surface, and then push the door leaf toward the door stop so that the lock body 20 fits against the base 10, so that the first locking member 14 engages with the second locking member 15 to lock the rotation of the lock body 20.

[0067] Preferably, when the door stop is fixed to the door leaf, the lock body 20 is first rotated to the first state and the door stop is in contact with the door leaf, the telescopic member 12 is adjusted to be displaced upward by a predetermined distance relative to the ground, and then the lock body 20 is rotated to the second state and the base body 11 is installed on the door leaf with the lower end of the telescopic member 12 positioned close to the ground, and finally the telescopic member 12 is moved upward to be in contact with the bottom end surface of the door leaf; alternatively, the telescopic member 12 of the door stop may be preset to have its maximum extension length at a predetermined distance from the recommended value of upward displacement after the above-mentioned positioning, or the telescopic value may be marked on the telescopic member for manual adjustment by the user.

[0068] Embodiment 1

[0069] The present embodiment relates to a door stop that acts on a door leaf to perform bidirectional locking on the door leaf. The door stop can be used to perform bidirectional locking on the opening and closing of the door leaf. Therefore, the door stop can be used when the door leaf is opened to any position in the middle, thereby preventing the door leaf from closing and further opening. This is called the bidirectional locking function of the door stop on the door leaf.

[0070] like Figure 1-2As shown, the door stop consists of a base 10 and a lock body 20, which are pivotally connected to each other, that is, the lock body 20 is rotatably pivotally connected to the base 10 around a pivot 100 as a rotation axis, and the base 10 is used to be fixed to the door leaf, for example, by gluing, so that the base 10 is fixed to the door leaf; the lock body 20 is used to pivot to contact with the ground and lock when the door leaf needs to be locked, that is, the door leaf is locked by the contact end 204 provided at one end of the lock body 20 contacting the ground (such as the floor).

[0071] like Figure 3 As shown, the base 10 is mainly composed of a base body 11 and a telescopic member 12. The base body 11 is used to be fixed to the door leaf, preferably fixed to one of the front and rear surfaces of the door leaf. The telescopic member 12 is used to be fitted and fixed to the lower surface of the door leaf, and the telescopic member 12 is arranged to be telescopic and movable along the up-down direction relative to the base body 11, wherein the up-down direction refers to the vertical direction parallel to one of the front and rear surfaces of the door leaf (i.e. Figure 3 up and down directions as shown in ).

[0072] In this embodiment, the base body 11 and the telescopic member 12 are both fixed to the door leaf by gluing, for example, 3M glue is pre-set on the first surface 101 and the second surface 102. When the user installs, the backing paper (i.e., release paper) of the 3M glue at the first surface 101 is first peeled off, and then the base 10 is fixed to the front and rear surfaces of the door leaf; then the backing paper of the 3M glue at the second surface 102 is peeled off (of course, it can also be peeled off at the same time as the release paper at the first surface 101), and the telescopic member 12 is adjusted to move upward so as to approach the lower surface of the door leaf until the second surface 102 is bonded and fixed to the lower surface of the door leaf. In other embodiments, the base body 11 and the telescopic member 12 can also be fixed to the front and rear surfaces and the lower surface of the door leaf by other known methods, such as screw fixing; or, only fixed at the first surface 101 and only fitted or close to the second surface 102 without fixed connection. In addition, the telescopic structure adopted by the base 10 can also play a role in adapting to the use of door leaves with different ground clearances.

[0073] The base body 11 is further divided into a fixed seat 111 and a pivot seat 13. The fixed seat 111 is a hollow rectangular seat body, and its interior is hollow to form a chamber for the telescopic member 12 to telescope therein. The pivot seat 13 is convexly arranged at one side of the fixed seat 111. A first pivot hole 131 is arranged on the side wall of the pivot seat 13. A first through hole 132 is arranged above the first pivot hole 131 and is spaced at an appropriate distance. The first pivot hole 131 is arranged near the middle of the pivot seat 13. The pivot 100 is arranged through the first pivot hole 131, that is, a pin shaft (not shown in the figure) is arranged in the first pivot hole 131 so that the lock body 20 is pivotally arranged around the pivot 100 relative to the base 10, and the first pivot hole 131 is used for the lock column 23 to be inserted therein when in the storage state.

[0074] The telescopic member 12 is an L-shaped flat member, whose side is L-shaped, has a certain width in the left and right directions and is slightly smaller than the fixed seat 111 so that it can be telescopically arranged. The telescopic member 12 can be divided into a vertical arm 121 and a horizontal arm 122, which are integrally formed and perpendicular to each other. The vertical arm 121 is telescopically arranged in the fixed seat 111, and the horizontal arm 122 is used to fit to the lower surface of the door leaf or be fixed there. The first surface 101 is formed by one side of the fixed seat 111, that is, the other side away from the pivot seat 13, and the second surface 102 is formed by the upper surface of the horizontal arm 122.

[0075] A first locking member 14 is also provided on the fixed seat 111 and is located below the pivot seat 13 to form a first locking assembly that can be locked or unlocked with a second locking member 15 provided on the lock body 20, so that the door can be locked in the first state.

[0076] like Figure 4-6 As shown, the lock body 20 includes a lock housing 21 and a housing cover 22, and a lock core 30 installed in the lock housing 21, wherein the main body of the lock core 30 is accommodated in the lock housing 21, and the part that needs to be operated can be exposed for user operation. After assembly, two rotating arms 211 and an arm cavity 212 formed between the two rotating arms 211 are formed at the upper end of the lock body 20, and arm shaft holes 213 are respectively provided on the two rotating arms 211, so that the lock body 20 is pivotally connected to the pivot seat 13 by a pin shaft.

[0077] The shell cover 22 is connected to the lower end of the lock core 30 and blocks the lower port of the lock shell 21. The shell cover 22 is made of soft glue material, such as rubber, so that when the lock body 20 rotates to the first state and locks the door leaf 401, the shell cover 22 can deform to store energy and increase friction. The resistance end 204 is formed on the surface of the shell cover 22 and a plurality of air cavities 205 are provided thereon to further increase friction and ensure that the door stop can provide sufficient locking force to the door leaf.

[0078] The door stop can achieve bidirectional locking of the door leaf. This is based on the lock body 20 being nearly vertically against the floor (or ground). Since the shell cover 22 is made of soft rubber, the vertical force and lateral friction can be increased due to its deformation. Furthermore, since the lock body 20, which was originally pivotally arranged relative to the base 10, is locked by the first locking assembly and cannot rotate, and the door stop is fixed by gluing at the first surface 101 and the second surface 102, since the two surfaces are perpendicular to each other, sufficient locking force can be provided when the door leaf 401 is opened or closed.

[0079] On the two side walls of the arm cavity 212, that is, on the two rotating arms 211, there are also lock holes 214 for the lock column 23 to be telescopically arranged therein, that is, the lock column 23 can be in a position such as Figure 4The lock body 20 is in the extended state shown, and can also be retracted to be flush with the surface of the rotating arm 211 after being driven by the lock core 30. Since the first through hole 132 is provided on the side wall of the pivot seat 13, when the lock body 20 rotates to the second state at the upper side, the lock column 23 is inserted into the first through hole 132 to lock the lock body 20 in this position, that is, to maintain it in the second state, so that the door stop is kept in the unlocked position. At this time, the lock body 20 is facing upward and close to the surface of the door leaf, so that the door stop can be stably stored when not in use, and the shape is relatively beautiful, such as Figure 1 shown.

[0080] like Figure 3-4 As shown, a first side opening 202 is formed on the first side surface of the lock body 20, and a first button 32 is assembled at the first side opening 202 so as to be movably set to slide up and down therein to lock or unlock the rotation of the lock body 20 relative to the base 10; a second side opening 203 is formed on the second side surface of the lock body 20, and a second button 33 is assembled at the second side opening 203 and is movably set to slide up and down therein to operate to lock or unlock the rotation of the lock body 20.

[0081] A second locking member 15 is also provided on the second side surface for locking the lock body 20 on the base 10 in the first state, and a first locking member 14 is correspondingly provided on the base body 11. In this embodiment, the first locking member 14 is mainly composed of a protruding member 141 protruding at the lower end of the fixing seat 111, and a locking hole 142 is provided thereon, and the second locking member 15 is composed of a recessed hole 151 recessed on the second side surface of the lock body 20 and a locking tongue 152 movably provided in the recessed hole 151. When the lock body 20 rotates to the first state, the protruding member 141 is inserted into the recessed hole 151 and the locking tongue 152 extends into the locking hole 142, thereby locking the lock body 20. Since the first locking member 14 and the second locking member 15 are arranged away from the pivot 100, the two locking members have sufficient locking strength for the lock body 20, and the locking tongue 152 is used to extend into the locking hole 142 in a direction parallel to the door leaf, so that the locking connection between them will not be pulled apart to cause accidental unlocking.

[0082] Preferably, the protrusion 141 is integrally formed on the fixing seat 111, and the recessed hole 151 is formed by a third through hole 206 formed on the second side surface of the lock housing 21 and a recessed cavity 301 formed on the lock core 30, so as to allow the protrusion 141 to pass through the third through hole 206 and then be assembled into the recessed cavity 301.

[0083] like Figure 5-6As shown, the lock core 30 includes a lock core body 31 which is a rectangular-shaped member as a whole, and has a U-shaped recess at the top and core arms on both sides. The lock column 23 is arranged at the core arm, and the first button 32 and the second button 33 are arranged on both sides of the lock core body 31. The lock core body 31 is composed of a lock core member 310 and an unlocking member 330. The unlocking member 330 is movably arranged up and down relative to the lock core member 310. The first button 32 and the second button 33 are both arranged on the unlocking member 330. A spring (not shown in the figure) is arranged between the unlocking member 330 and the lock core member 310 so that the unlocking member 330 is initially in an upper position, and the first button 32 or the second button 33 is forced to move the unlocking member 330 downward ( Figure 6 In the downward direction), the locking column 23 is driven to retract and unlock.

[0084] like Figure 6 As shown, a mounting hole 311 is provided on the lock core component 310 for the unlocking component 330 to be assembled therein and capable of moving up and down therein, and locking protrusions 334 for engaging with the side walls of the mounting hole 311 are respectively provided on the inner and outer sides of the side edges of the unlocking component 330. The lock core component 310 is formed as a strip-shaped side wall at the side wall of the mounting hole 311 for engaging between the two locking protrusions 334, thereby realizing the assembly connection and the upward and downward movable setting of the unlocking component 330 relative to the lock core component 310.

[0085] The lock tongue 152 is arranged at the upper end of the unlocking member 330 and extends upward. There are cavities on both sides of the lock tongue 152 to form a concave cavity 301. Driving arms 332 are respectively arranged on both sides of the upper end of the unlocking member 330 to drive the swing member 320 to move and drive the lock column 23 to move in the lock hole 214. The swing member 320 is composed of two swing arm members 321 that are symmetrically arranged on the ground. Each swing arm member 321 is rotatably arranged with a swing shaft 340 as an axis. For example, a swing column 312 is arranged on the lock core member 310, and a swing shaft hole 322 is arranged at the middle of the swing arm member 321. The swing shaft hole 322 is sleeved on the swing column 312. Since the two swing arm members 321 are symmetrically arranged, their respective swing shafts 340 are parallel to each other. Preferably, the swing shaft hole 322 is arranged at the middle position of the swing arm member 321, the lock column 23 is arranged at the upper end of the swing arm member 321 and can extend from the lock hole 214, and the spring acts between the inner side of the lower end of the swing arm member 321 and the spring seat 313 arranged on the lock core member 310, so that the lock column 23 is initially maintained extending from the lock hole 214; a first contact surface 323 is formed at the outer side of the lower end of the swing arm member 321, and a second contact surface 333 is provided on the inner side wall of the driving arm 332. When the unlocking member 330 is displaced downward under the action of the first button 32 or the second button 33, the second contact surface 333 acts on the first contact surface 323 to rotate around the pivot shaft 340, and the lock column 23 retracts into the lock hole 214.

[0086] The installation process of the door stop is as follows:

[0087] First, the door stop is fixed at a predetermined position on the door leaf 401, wherein the position of the door stop is required, that is, the fixed position of the door stop in the up and down directions is related to its locking function. When fixing, ensure that the length of the working section of the lock body 20 is greater than the distance from the pivot 100 to the ground. The length of the working section of the lock body 20 refers to the distance from the end of the lock body 20 to the pivot 100 in the natural state.

[0088] Specifically, it can be one of the following

[0089] 1. Adjust the installation length of the telescopic member 12 relative to the base 10, so as to control the installation position of the door stop on the door leaf.

[0090] Users can operate as follows:

[0091] As shown in reference 7, the door stop is first adjusted to the first state, and then it is attached to the vicinity of the lower end of the door leaf 401 so that the abutment end 204 at the lower end of the lock body 20 contacts the ground 402, and the telescopic state of the telescopic member 12 is adjusted to retract it upward by a certain distance d1 relative to the base body 11.

[0092] Then, the lock body 20 is rotated to a position deviating from the first state, for example, to a second position, such as Figure 8 As shown, the first surface 101 is glued and fixed to the front surface of the door leaf 401. Finally, the telescopic member 12 is moved upward until the second surface 102 is glued and fixed to the bottom end surface of the door leaf, forming a Fig. 9 The installation state shown is also the second state of the door stop (or the storage state).

[0093] 2. Other position adjustments

[0094] Of course, when adjusting d1, it is also possible not to fit the door stop to the lower end of the door leaf 401 to be installed for reference operation, but to adjust the door stop to the first state and place it vertically on a reference plane (for example, roughly vertically on a table top), and then adjust the telescopic member 12 to retract upward by a distance d1.

[0095] Alternatively, the upward retraction distance d1 of the telescopic member 12 can be manually adjusted without relying on the reference plane. At this time, an appropriate value or gear position can be marked on the telescopic member 12. When the user installs, adjust the telescopic position of the telescopic member 12 according to his own needs and press Figure 8-9 Install as shown.

[0096] Alternatively, the structure of the telescopic member 12 is designed to limit its maximum telescopic distance, and its maximum extended position is the state after a preset retracted distance d1, that is, no user adjustment function is provided but it is preset at the factory.

[0097] Secondly, after the door stop is fixed, the user can operate the door stop state to achieve bidirectional locking of the door leaf. The process is as follows:

[0098] In order to operate the door leaf and the door stop to lock the door leaf in both directions, the door leaf is first opened to the position to be locked, and then the lock body 20 is rotated until its end contacts the bottom surface, and then the door leaf is pushed toward the door stop so that the lock body 20 fits against the base 10 and the first locking member 14 engages with the second locking member 15 to lock the rotation of the lock body 20, thereby forming a locked state of the door stop and locking the door leaf so that it cannot be opened or closed.

[0099] In addition, when unlocking, the first button 32 is driven to move to unlock the first locking assembly, and the lock body 20 is rotated to the second state so that the lock body 20 fits the surface of the door leaf, thereby achieving unlocking and storage.

[0100] In order to evaluate the actual effect of the door stop, the door stop of Example 1 was 3D printed to make a prototype, and the prototype door stop was tested for locking effect. 3M glue was installed on the first surface 101 and the second surface 102 of the prototype. The floor of the test site was a composite floor. The tested door leaf was an inward-opening indoor wooden door. The door stop was installed on the front surface of the door leaf. The test scene was as follows: Fig.10 shown.

[0101] After repeated testing, the following test results were obtained:

[0102] 1. When the retraction distance d1 is 3mm, the measured data of the locking force for opening the door are all greater than 30kg, and the measured data of the locking force for closing the door are all greater than or equal to 15kg.

[0103] 2. When the retraction distance d1 is 4mm, the measured data of the locking force for opening the door are all greater than 30kg, and the measured data of the locking force for closing the door are all greater than or equal to 16kg.

[0104] 3. When the retraction distance d1 is 5 mm, the measured data of the locking force for opening the door are all greater than 30 kg, and the measured data of the locking force for closing the door are all greater than or equal to 20 kg.

[0105] The measurement data is listed below:

[0106] Table 1 Bidirectional locking force test table

[0107] Serial number Distance d1 Door opening locking force Door closing force 1 3mm >30kg ≥15kg 2 4mm >30kg ≥16kg 3 5mm >30kg ≥20kg

[0108] It can be seen that after the door stop of the present invention is installed, the door opening locking force can be greater than 30kg, and the door closing locking force can be greater than or equal to 15kg, which fully meets the needs of two-way locking of door leaves in daily life and meets the requirements of this use scenario of indoor door locking. In addition, the door stop is beautiful and easy to install and operate.
