Description

[Technical Field]

[0001] This utility model relates to a door frame. [Background Technology]

[0002] Currently, common infant safety gates on the market are mainly installed on door frames of rooms or houses to limit the range of movement of infants and toddlers, prevent them from entering and leaving the room at will, and ensure their safety. However, most existing gate designs are only designed for the protection of infants and toddlers and lack consideration for the adaptation to family pets.

[0003] In a home environment, many users need to prevent infants and young children from running out at will, while also wanting pets (such as cats and dogs) to be able to come and go freely or have their access restricted. Therefore, this utility model was developed to address these needs. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a gate with a simple structure. This gate can both limit the activity range of infants and toddlers to ensure safety and adjust the access permissions for pets according to actual needs. It can allow pets to pass freely in both directions, restrict pets to enter only or exit only, or completely close the passage to prevent pets from entering or exiting. Therefore, this invention provides an adjustable access passage for pets while ensuring the safety of infants and toddlers, and supports multiple operating modes (such as free passage, one-way restriction, or complete closure) to meet the diverse needs of families.

[0005] This utility model is achieved through the following technical solution:

[0006] A gate includes a frame with a gate that can be opened or closed connected to the frame. The lower part of the gate has a passageway for pets to enter and exit. A baffle that can rotate relative to the gate to open or close the passageway is also connected to the gate. The baffle has an upper side, a lower side, an outer side, and an inner side. The gate has a control component that can move relative to the baffle to lock or unlock it. The control component can be positioned in a locked position, a first unlocked position, a second unlocked position, and a third unlocked position. When the control component is in the locked position, it locks the baffle and prevents it from opening the passageway. When the control component is in the first unlocked position, it disengages from the baffle, allowing the baffle to rotate inward or outward to open the passageway. When the control component is in the second unlocked position, it engages with the outer side, allowing the baffle to rotate only inward to open the passageway. When the control component is in the third unlocked position, it engages with the inner side, allowing the baffle to rotate only outward to open the passageway.

[0007] The upper part of the baffle is rotatably connected to the door body. The control component includes a body that can rotate relative to the door body. The body is provided with an outer control block and an inner control block. The outer control block includes a first stop and a second stop provided on the body. A first connecting surface and a second connecting surface connecting the first stop and the second stop are provided. The inner control block includes an inner stop provided on the body. The inner control block also includes a third connecting surface and a fourth connecting surface that connect with the inner stop. When the control component rotates to the locked position, the outer and inner surfaces extend into the first stop and the door body. The inner stop block forms a locking groove, preventing the baffle from rotating. When the control component rotates to the first unlock position, the first and third connecting surfaces are opposite to and below the lower side, allowing the baffle to rotate inward or outward. When the control component rotates to the second unlock position, the fourth connecting surface is below the lower side and the second stop block is opposite to the outer side, allowing the baffle to rotate only inward. When the control component rotates to the third unlock position, the second connecting surface is below the lower side and the inner stop block is opposite to the inner side, allowing the baffle to rotate only outward.

[0008] The door has a connecting frame, the inner side of which forms the passage. A connecting post is provided on the baffle near its upper side. The connecting post is rotatably connected to the connecting frame, allowing the baffle to rotate relative to the door. The main body is rotatably connected to the connecting frame, and the main body has an operating knob exposed on the connecting frame.

[0009] One side of the door is rotatably connected to the frame, and a locking mechanism is provided between the other side of the door and the frame. The locking mechanism includes a locking hole on the frame and a locking seat on the door. The locking seat contains a locking block that can slide inside and engage or disengage with the locking hole. The locking block has a first inclined surface. The upper side of the locking seat has a button that can push the first inclined surface to disengage the locking block from the locking hole when pressed. A first return spring is provided between the locking seat and the locking block to push the locking block to slide back to its original position. A second return spring is provided between the locking seat and the button to push the button to reset. The frame has a third inclined surface that can squeeze the locking block to slide into the locking seat when the door is rotated and closed.

[0010] The lower side of the locking seat is also provided with a second locking mechanism. The second locking mechanism includes a movable block that can rotate relative to the locking seat. The movable block can stop in two positions: a locking position and a releasing position. When the movable block is in the locking position, the abutment rod on the movable block abuts against the locking block to prevent the locking block from disengaging from the locking hole. When the movable block moves to the releasing position, the abutment rod disengages from the locking block, creating a space for the locking block to disengage from the locking hole. A third return spring is provided between the locking seat and the movable block to push the movable block back to its original position.

[0011] The locking seat is provided with an observation hole, and the locking block is provided with a first color coating that can be displayed through the observation hole when it is engaged with the locking hole. The locking block is also provided with a second color coating that can be displayed through the observation hole when it is disengaged from the locking hole.

[0012] The door body is provided with a horizontally sliding locking block on the lower part of the same side as the locking seat. A fourth return spring is provided between the locking block and the door body to push the locking block to slide and reset. The frame is provided with a locking seat. The locking seat is provided with a locking groove that can engage with the locking block and be engaged in the locking mechanism. When the door body is unlocked and lifted, the locking seat is provided with a second inclined surface that can squeeze the locking block to slide into the door body when the door body is lowered and rotated to close.

[0013] The door body is provided with a connecting seat, the connecting seat is provided with a connecting shaft, the frame body is provided with a fixed seat that is rotatably connected to the connecting seat, the fixed seat is provided with a connecting sleeve that is sleeved with the connecting shaft, the lower side of the connecting seat is provided with a positioning part, the fixed seat is provided with a first positioning groove and a second positioning groove located above the first positioning groove, the first positioning groove and the second positioning groove are connected by an inclined surface, when the positioning part is engaged with the first positioning groove, the door body is in a closed state, when the positioning part moves to engage with the second positioning groove, the door body is in an open state.

[0014] The lower end of the connecting shaft is provided with a step extending outward, and a fourth return spring is provided between the step and the inner top surface of the connecting sleeve, which can push the door body to move downward when the positioning part is disengaged from the second positioning groove.

[0015] The door body is provided with a downwardly extending connecting rod on the same side as the connecting seat. The connecting rod is inserted into the frame and can rotate and move up and down within the frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. When the door of this utility model is closed relative to the frame, it can restrict the activity range of infants and toddlers, preventing them from running out of the room at will and ensuring safety. The independently set passage on the door allows small pets such as cats and dogs to pass through. The control component for the barrier on the passage can control the barrier in multiple states, allowing users to adjust the pet's access permissions according to actual needs. When it is desired that the pet is also confined to the room and other pets are not allowed to enter, the control component is adjusted to the locked position to prevent the barrier from opening the passage. When it is desired that the pet can freely enter and exit the room, the control component is adjusted to the first unlocked position, at which time the barrier can be rotated inward or outward to open the passage, allowing the pet to push the barrier open freely. When it is desired that external pets enter the room and wish to enter freely... When a pet is confined to the room, the control unit is adjusted to the second unlock position. In this position, the outer side of the barrier is blocked by the control unit, and the barrier can only rotate inwards, not outwards. The pet can only push the barrier open from the outside to enter the room, but cannot push it open from the inside out. When it is desired that the pet can leave the room and be prevented from re-entering, the control unit is adjusted to the third unlock position. In this position, the inner side of the barrier is blocked by the control unit, and the barrier can only rotate outwards, not inwards. The pet can only push the barrier open from the inside to run outside, but cannot push it open from the outside in. Therefore, this utility model door provides an adjustable entry and exit passage for pets while ensuring the safety of infants and young children. It also supports multiple operating modes (such as free passage, one-way restriction, or complete closure) for users to choose from, meeting the diverse needs of families.

[0018] 2. The locking mechanism of this utility model has a double-lock structure. When it is necessary to open the door, the movable block must be operated first to make the movable block make way for the movement of the locking block before the button can be pressed. Through multi-step operation, it can prevent children from accidentally operating the button and opening the door, thus ensuring safety.

[0019] 3. The frame of this utility model's door frame is also equipped with a locking seat, which has a locking groove. The locking block on the door body engages with the locking groove, and the locking block only disengages from the locking groove after the locking mechanism is unlocked and the door body is lifted. Only when the locking block disengages from the locking groove can the door body rotate relative to the frame and open. Therefore, opening this utility model's door frame requires first unlocking the locking mechanism and then lifting the door body until the locking block disengages from the locking groove, thereby preventing children from accidentally opening the door frame and further ensuring safety.

Detailed Implementation Methods

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] like Figures 1 to 12As shown, a doorway includes a frame 1 with a door 2 that can be opened or closed. When the door 2 is closed, infants and toddlers are confined to the room, their movement is restricted, preventing them from running around and ensuring safety. When an adult controls the door 2 to open relative to the frame 1, infants and toddlers can enter and exit under adult supervision. The lower part of the door 2 has a passage 3 for pets to enter and exit. When the door 2 is closed relative to the frame 1, this independent passage 3 allows small pets such as cats and dogs to pass through. The door 2 is also connected to a baffle 4 that can rotate relative to it to open or close the passage 3. The baffle 4 has an upper side 41, a lower side 42, an outer side 43, and an inner side 44. The door 2 is provided with a control component 5 that can move relative to it to lock or unlock the baffle 4. The control component 5 can stop in the following positions: locked position, first unlocked position, second unlocked position, and third unlocked position. When the control component 5 is in the locked position, it locks the baffle 4 and prevents it from opening the passage 3. When the control component 5 is in the first unlocked position, it disengages from the baffle 4, and the baffle 4 can rotate inward or outward to open the passage 3. When the control component 5 is in the second unlocked position, it cooperates with the outer side 43 so that the baffle 4 can only rotate inward to open the passage 3. When the control component 5 is in the third unlocked position, it cooperates with the inner side 44 so that the baffle 4 can only rotate outward to open the passage 3. Specifically, when it is desired that the pet be confined to the room and other pets are not allowed to enter, the control component 5 is adjusted to the locked position, which prevents the barrier 4 from opening the passage 3. When it is desired that the pet can freely enter and exit the room, the control component 5 is adjusted to the first unlocked position, at which point the barrier 4 can rotate inward or outward to open the passage 3, allowing the pet to push against the barrier 4 to enter and exit freely. When it is desired that an external pet enter the room and be confined there after entering, the control component 5 is adjusted to the second unlocked position, at which point the outer side of the barrier 4... The control component 5 can block the door, allowing the barrier 4 to rotate only inwards and not outwards. This means the pet can only push the barrier 4 open from the outside to enter the room, not from the inside out. When it's desired that the pet can leave the room and be prevented from re-entering, the control component 5 is adjusted to the third unlocked position. In this position, the inner side 44 of the barrier 4 is blocked by the control component 5, allowing the barrier 4 to rotate only outwards and not inwards. This means the pet can only push the barrier 4 open from the inside to escape the room, not from the outside in. Therefore, this door provides an adjustable entry and exit route for pets and supports multiple operating modes (such as free passage, one-way restriction, or complete closure) to meet diverse family needs.

[0043] like Figures 3 to 12As shown, the upper part of the baffle 4 is rotatably connected to the door body 2. The control component 5 includes a body 51 that can rotate relative to the door body 2. The body 51 is provided with an outer control block 52 and an inner control block 53. The outer control block 52 includes a first stop 521 and a second stop 522 provided on the body 51. A first connecting surface 523 and a second connecting surface 524 connecting the first stop 521 and the second stop 522 are provided. The inner control block 53 includes an inner stop 531 provided on the body 51. The inner control block 531 also includes a third connecting surface 532 and a fourth connecting surface 534 that are connected to the inner stop 531. When the control component 5 rotates to the locked position, the... The outer side 43 and inner side 44 extend into the locking groove 54 formed by the first stop 521 and the inner stop 531. If the baffle 4 rotates inward or outward, the inner side 44 will be blocked by the inner stop 531 and the outer side 43 will be blocked by the first stop 521, preventing the baffle 4 from rotating and ensuring the pet cannot freely enter or exit. When the control component 5 rotates to the first unlock position, the first connecting surface 523 and the third connecting surface 532 are opposite to and below the lower side 42, allowing the baffle 4 to rotate inward or outward. At this time, the control component 5 and the baffle 4 are completely disengaged and do not interfere with each other. The baffle 4 can rotate freely, and the pet can push open the baffle 4 from the inside or outside to escape. When the control component 5 is rotated to the second unlock position, the fourth connecting surface 533 is located below the lower side surface 42, and the second stop 522 is opposite to the outer side surface 43, so the baffle 4 can only rotate inward. At this time, since the fourth connecting surface 533 is located below the lower side surface 42, the inward rotation of the baffle 4 will not be interfered with by the control component 5. However, since the second stop 522 is opposite to the outer side surface 43, if the baffle 4 rotates outward, it will be blocked by the second stop 522. Therefore, when the control component 5 is in the second unlock position, the baffle 4 can be pushed open from the outside by the pet and rotated inward. The pet can enter the room from the outside through the passage 3. Once inside the room, the pet will not be able to push open the baffle 4 from the outside. When the control component 5 is rotated to the third unlock position, the second connecting surface 524 is located below the lower side surface 42 and the inner stop block 531 is opposite to the inner side surface 44, so the baffle 4 can only rotate outward. At this time, since the second connecting surface 524 is located below the lower side surface 42, the outward rotation of the baffle 4 will not be blocked by the control component 5. However, since the inner stop block 532 is opposite to the inner side surface 44, if the baffle 4 rotates inward, it will be blocked by the inner stop block 531. Therefore, when the control component 5 is in the third unlock position, the baffle 4 can be pushed open from the inside by the pet and rotate outward. The pet can enter the outside of the room through the passage 3 from the inside. Once the pet reaches the outside of the room, it will not be able to push open the baffle 4 from the inside to enter.

[0044] like Figure 1 and Figure 2 As shown, the door body 2 has a connecting frame 26, the inner side of the connecting frame 26 forms the channel 3, the baffle 4 has a connecting post 45 located on its upper side 41, the connecting post 45 is rotatably connected to the connecting frame 26 so that the baffle 4 can rotate relative to the door body 2, the body 51 is rotatably connected to the connecting frame 26, the body 51 has an operating knob 55 exposed on the connecting frame 26, by rotating the operating knob 55 the position of the control component 5 can be easily changed so that the door has the required working mode.

[0045] like Figures 13 to 15 As shown, one side of the door body 2 is rotatably connected to the frame 1, and a locking mechanism is provided between the other side of the door body 2 and the frame 1. The locking mechanism includes a locking hole 61 on the frame 1, a locking seat 62 on the door body 2, and a locking block 63 inside the locking seat 62 that can slide within it and engage or disengage from the locking hole 61. The locking block 63 has a first inclined surface 64. The upper side of the locking seat 62 has a button 65 that can push the first inclined surface 64 when pressed, causing the locking block 63 to disengage from the locking hole 61. A first return spring 66 is provided between the locking seat 62 and the locking block 63 to push the locking block 63 to slide back to its original position. A second return spring 67 is provided between the locking seat 62 and the button 65 to push the button 65 to its original position. When unlocking, the button 65 is pressed first, which pushes the first inclined surface 64, thereby disengaging the locking block 63 from the locking hole 61. Once disengaged, the locking mechanism is unlocked. However, to prevent children from accidentally pressing button 65 and causing a safety risk of accidental locking, a second locking mechanism is provided on the lower side of the locking seat 62. That is, when unlocking the locking structure, the second locking mechanism must be operated first, and then button 65 must be pressed. Specifically, the second locking mechanism includes a movable block 681 that can rotate relative to the locking seat 62. The movable block 681 can stop in two positions: a locking position and an unlocking position. When the movable block 681 is in the locking position, the abutment rod 682 on the movable block 681 abuts against the locking block 63 to prevent the locking block 63 from disengaging from the locking hole 61. When the movable block 681 moves to the unlocking position, the abutment rod 682 disengages from the locking block 63, making room for the locking block 63 to disengage from the locking hole 61. A third return spring 683 is provided between the locking seat 62 and the movable block 681 to push the movable block 681 back to its original position. When the locking mechanism needs to be unlocked, the movable block 681 is operated first to make room for the movement of the locking block 63. Only after the position is made available can the locking block 63 move, and then the button 65 can be pressed. Through this multi-step operation, children can be prevented from accidentally operating the button 65 to open the door, thus ensuring safety.

[0046] like Figure 13As shown, the locking seat 62 is provided with an observation hole 621, and the locking block 63 is provided with a first color coating 631 that can be displayed through the observation hole 621 when it is engaged with the locking hole 61. The locking block 63 is also provided with a second color coating 632 that can be displayed through the observation hole 621 when it is disengaged from the locking hole 61. The first color layer 631 and the second color layer 632 are different colors, so the user can identify whether the locking mechanism is truly and completely locked through the observation hole 621 to determine the status of the locking mechanism, avoid false locking, and ensure safety.

[0047] like Figure 16 , Figure 17 and Figure 21 As shown, a horizontally sliding locking block 71 is provided on the lower part of the door body 2, located on the same side as the locking seat 62. A fourth return spring 72 is provided between the locking block 71 and the door body 2 to push the locking block 71 to slide back to its original position. A locking seat 73 is provided on the frame 1. The locking seat 73 has a locking groove 74 that can engage with the locking block 71 and disengage from the locking block 71 when the locking mechanism is unlocked and the door body 2 is lifted. The locking seat 73 has a second inclined surface 75 that can squeeze the locking block 71 to slide inward into the door body 2 when the door body 2 is rotated to close. The locking block 71 on the door body 2 cooperates with the locking groove 74, and the locking block 71 disengages from the locking groove 74 only after the locking mechanism is unlocked and the door body 2 is lifted. Only after the locking block 71 disengages from the locking groove 74 can the door body 2 rotate relative to the frame 1 and open. Therefore, opening the door requires first unlocking the locking mechanism and then lifting the door 2 until the locking block 71 disengages from the locking groove 74, thus preventing children from accidentally opening the door and further ensuring safety. Additionally, as... Figure 14 As shown, the frame 1 is provided with a third inclined surface 69 that can press the locking block 63 into the locking seat 62 when the door 2 is rotated and closed. When the door 2 is closed, the door 2 is rotated, the locking block 71 contacts the second inclined surface 75 and is pressed by the second inclined surface 75 and slides into the door 2, the locking block 63 contacts the third inclined surface 69 and is pressed by the third inclined surface 69 and slides into the locking seat 62. Once the locking block 71 is aligned with the locking groove 74 again and the locking block 63 is aligned with the locking hole 61, the fourth return spring 72 pushes the locking block 71 to engage with the locking groove 74 again, and the first return spring 66 pushes the locking block 63 to engage with the locking hole 61 again, so that the door 2 is firmly locked.

[0048] like Figures 17 to 20As shown, the door body 2 is provided with a connecting seat 21, and the connecting seat 21 is provided with a connecting shaft 22. The frame 1 is provided with a fixed seat 11 that is rotatably connected to the connecting seat 21. The fixed seat 11 is provided with a connecting sleeve 12 that is sleeved with the connecting shaft 22. The lower side of the connecting seat 21 is provided with a positioning part 23. The fixed seat 11 is provided with a first positioning groove 13 and a second positioning groove 14 located above the first positioning groove 13. The first positioning groove 13 and the second positioning groove 14 are connected by an inclined surface 15. When the positioning part 23 is engaged with the first positioning groove 13, the door body 2 is in a closed state. When the positioning part 23 moves to engage with the second positioning groove 14, the door body 2 is in an open state. When the door body 2 is in a closed state, the engagement of the first positioning groove 13 and the positioning part 23 can securely position the door body 2 on that side. When the second positioning groove 14 engages with the positioning part 23, the door body 2 can be positioned in an open state, facilitating the entry and exit of infants and adults.

[0049] like Figure 20 As shown, the lower end of the connecting shaft 22 is provided with an outwardly extending step 24. Between the step 24 and the inner top surface 121 of the connecting sleeve 12, a fourth return spring 8 is provided, which can push the door body 2 downward when the positioning part 23 is disengaged from the second positioning groove 14. When the door body 2 is in the open state, the positioning part 23 is in the second positioning groove 14 at a higher position. At this time, the fourth return spring 8 is in a compressed state. When it is necessary to close the door body 2, simply rotate the door body 2 to disengage the positioning part 23 from the second positioning groove 14. The fourth return spring 8 can then push the positioning part 23 on the door body 2 to slide down the inclined surface 15. The door body 2 rotates and descends at the same time. During the rotation, the locking block 73 engages with the locking groove 74, and the locking block 63 also engages with the locking hole 61, thereby achieving the closed and locked state again.

[0050] like Figure 17 As shown, the door body 2 is provided with a downwardly extending connecting rod 25 on the same side as the connecting seat 21. The connecting rod 25 is inserted into the frame 1 and can rotate and move up and down within the frame 1.

[0051] The present invention has 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 invention.
