Description

Technical Field

[0001] The present invention relates to the technical field of furniture access control, and in particular to a smart home access control device. Background Art

[0002] Access control is a device used to prevent strangers from entering a specific area, usually installed on the wall.

[0003] The existing devices of this type have the problem of inconvenient closing. For example, a smart home access control device disclosed in the Chinese patent publication number "CN218214205U" needs to press the push rod to move downward when in use to drive the clamping block to move to the right, so that the clamping block is moved out of the groove of the device to achieve the removal of the access control device. However, the left side of the clamping block of the device is in close contact with the inside of the groove. Since the groove is rectangular, the left side of the clamping block is also rectangular, which results in the need to press the push rod to move the clamping block to the right and move it out of the inside of the groove to return the protrusion to a position where it can cooperate with the clamping block, that is, the left side of the clamping block can be in close contact with the inside of the groove. If the push rod is not pressed, when the protrusion returns to a position where it can cooperate with the clamping block, the position of the protrusion will be blocked by the left side of the clamping block, which makes the closing of the device inconvenient. Accordingly, the present application proposes a smart home access control device. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1: Reference Figure 3 , Figure 4 , Fig.10 , Fig.11

[0039] Reference Figure 1A smart home access control device includes a locking mechanism, an ash suction mechanism, and an alarm mechanism. The locking mechanism includes a door panel 4, a handle 25, a connecting plate 8, a No. 1 mounting block 9, a No. 2 mounting block 10, a plug plate 19, a card plate 20, a reset spring 21, a locking spring rod 27, a protrusion 22, a locking rod 23, a sleeve 24, a pressure plate 26, an opening spring 28, a connecting pin 29, and a rotating shaft 30. The locking mechanism is used to lock the door panel 4. The reset spring 21 is fixedly connected between the connecting plate 8 and the No. 1 mounting block 9, the No. 1 mounting block 9 is fixedly connected to the frame 1, the sleeve 24 is rotatably connected to the door panel 4, and the ash suction box 11 is magnetically connected to the door panel 4.

[0040] The locking rod 23 is fixedly connected to the No. 2 mounting block 10, the door panel 4 is slidably connected to the frame 1, the card plate 20 is fixedly connected to the connecting plate 8, the plug plate 19 is slidably connected to the connecting plate 8, the plug plate 19 is fixedly connected to the No. 1 mounting block 9, the locking spring rod 27 is fixedly connected to the No. 2 mounting block 10, the No. 2 mounting block 10 is fixedly connected to the door panel 4, the locking spring rod 27 is fixedly connected to the pressure plate 26, the handle 25 is connected to the rotating shaft 30 through the connecting pin 29, the front end of the connecting pin 29 is inserted into the handle 25, the sleeve 24 is sleeved on the rotating shaft 30, the rear end of the connecting pin 29 is inserted into the rotating shaft 30, the rotating shaft 30 is slidably connected to the protrusion 22, and the lower end of the card plate 20 is in contact with the locking rod 23.

[0041] It should be noted that if Figure 1 As shown, before using the device, half of the frame 1 needs to be buried in the part of the wall where the rack box 2 is located, and the part where the rack box 2 is located is covered by the wall. At the same time, a groove for opening and closing the door panel 4 needs to be left on the wall, that is, it cannot affect the sliding of the door panel 4 in the frame 1. The other half of the frame 1 can be exposed, so that the side wall of the other half of the frame 1 where the camera 7 is located is in contact with the other wall, and the side of the door panel 4 with the handle 25 is placed outward, so that the device can be installed.

[0042] In this embodiment, reference Fig.10 The locking spring rod 27 will push the pressure plate 26 toward the direction of the protrusion 22, and the upper end of the pressure plate 26 will be pressed on the upper surface of the connecting plate 8. Since the locking spring rod 27 is fixedly connected to the No. 2 mounting block 10, the upward and downward movement of the connecting plate 8 will be restricted by the pressure plate 26. At the same time, since the card plate 20 is fixedly connected to the connecting plate 8, its position will also be restricted, making it impossible for the locking rod 23 to be pulled out.

[0043] For further reference, Fig.10 and Fig.11The connecting pin 29 connects the handle 25 with the rotating shaft 30, so that the power of the user turning the handle 25 can be transmitted to the rotating shaft 30. At the same time, the connecting pin 29 can be pulled out from the handle 25 and the rotating shaft 30. When the connecting pin 29 is pulled out, the power of the user turning the handle 25 cannot be transmitted to the rotating shaft 30. At this time, due to the action of the locking spring rod 27, the pressing plate 26 is pressed on the upper surface of the connecting plate 8, and the connecting plate 8 cannot move up and down, and the protrusion 22 cannot rotate either. Therefore, the door panel 4 of the present device is in a locked and immovable state.

[0044] Further, when the connecting pin 29 is in Fig.10 When the handle 25 is in the locked state, the protrusion 22 can be pushed toward the protrusion 22 by pressing the connecting pin 29, so that the connecting pin 29 moves the pressure plate 26 away from the protrusion 22. Since the pressure plate 26 is no longer in contact with the upper surface of the connecting plate 8, and because the connecting pin 29 connects the handle 25 and the rotating shaft 30, the power of the user turning the handle 25 can be transmitted to the rotating shaft 30. At this time, the protrusion 22 can also rotate with the rotation of the rotating shaft 30, thereby pushing the connecting plate 8 upward, so that the card plate 20 and the locking rod 23 are out of contact, and the locking rod 23 can be pulled out from the No. 1 mounting block 9.

[0045] Embodiment 2:

[0046] Different from the first embodiment, Figure 1 , Figure 3 , Figure 6 as well as Figure 7 The ash suction mechanism includes a frame 1, a push rod 5, an ash suction box 11, an ash suction spring 12, a guide rod 13, a rubber plate 14, a block 15, a baffle 16, an ash suction spring rod 17, and a filter 18. The ash suction mechanism is used for sucking ash. There are two blocks 15, one of which is fixedly connected to the filter 18, and the other block 15 is fixedly connected to the ash suction spring rod 17. The ash suction spring rod 17 is fixedly connected to the ash suction box 11. The push rod 5 is fixedly connected to the side wall of the frame 1, the rubber plate 14 is slidably connected to the guide rod 13, the guide rod 13 is fixedly connected between the inner walls of the ash suction box 11, the ash suction spring 12 is fixedly connected between the inner wall of the ash suction box 11 and the rear wall of the rubber plate 14, and a camera 7 is arranged on the frame 1.

[0047] Specifically, the camera 7 can record people near the device, and the user of the device can view people near the device in real time through the APP, which is a prior art.

[0048] In this embodiment, the rectangular portion at the bottom end of the stopper 15 and the baffle 16 is located at a groove on the dust absorption box 11. Since the half of the frame 1 with the rack box 2 is located in the wall and is limited by the narrow space, the dust accumulation in this part of the frame 1 will be more serious. At the same time, due to the effect of gravity, the dust will fall on the lower inner wall of the frame 1. At the same time, since the door panel 4 will generate friction on the upper inner wall of the frame 1 when opening and closing, the dust on the upper inner wall of the frame 1 will fall down and fall on the lower inner wall of the frame 1.

[0049] Furthermore, when the door panel 4 of the device is opened, the two blocks 15 will be opened by the push rod 5. Because the front end of the block 15 is an inclined surface, when the inclined surface at the front end of the block 15 contacts the push rod 5, the push rod 5 will push one block 15 upward and press the other block 15 downward to separate them. At the same time, the filter screen 18 is connected to the upper block 15, so when the upper block 15 moves upward, the filter screen 18 will also move upward, and at the same time drive the baffle 16 to move upward. At this time, the push rod 5 will push the rubber plate 14 to move in the direction away from the block 15. Since the rubber plate 14 is arranged in the ash absorption box 11, the structure in the ash absorption box 11 is similar to a syringe. When the rubber plate 14 moves in the direction away from the block 15, the state of the ash absorption box 11 is similar to that of a syringe sucking liquid, so dust can be sucked into the ash absorption box 11 from the groove at the bottom of the side wall of the ash absorption box 11.

[0050] Embodiment three:

[0051] The alarm mechanism includes a rack box 2, rack teeth 3, a gear 31, an alarm spring rod 32, a glass tube 33, a pull rod 34, a check block 35, a wire rope 37, a friction block 38, a spring 39, a No. 1 wire wheel 40, a No. 2 wire wheel 41, a slide plate 42, a synchronous shaft 43, a knocking rod 44, a hollow shell 45, and an impact block 46. The alarm assembly is used for prying doors and alarming in case of fire.

[0052] The hollow shell 45 is fixedly connected to the door panel 4, the alarm spring rod 32 is fixedly connected to the pull rod 34, the front end of the alarm spring rod 32 is fitted with the glass tube 33, the rack teeth 3 are rotatably connected to the rack box 2, the rack box 2 is fixedly connected to the side wall of the frame 1, the impact block 46 is slidably connected to the knock rod 44, the rear end of the check block 35 is fixedly connected with the check spring 36, the friction block 38 is fixedly connected to the door panel 4, and the friction block 38 is fitted with the other end of the spring 39.

[0053] The synchronization shaft 43 is fixedly connected to the gear 31, the knocking rod 44 and one end of the mainspring 39. The No. 1 wire wheel 40 and the No. 2 wire wheel 41 are rotatably set in the door panel 4. The wire rope 37 is wound around the No. 1 wire wheel 40. The wire rope 37 fits the No. 2 wire wheel 41. One end of the wire rope 37 is fixedly connected to the slide plate 42. The slide plate 42 is slidably connected to the side wall of the door panel 4. The other end of the wire rope 37 is fixedly connected to the check block 35. The glass tube 33 is inserted into the door panel 4.

[0054] It should be noted that the structures of the dust suction spring rod 17, the locking spring rod 27 and the alarm spring rod 32 in the device are the same, only the sizes are different. For details, refer to Fig.12 The position of the slide plate 42 is located at Fig.15 When in the position, the slide plate 42 is just in front of the connecting plate 8, and the height dimension of the slide plate 42 is greater than the thickness dimension of the connecting plate 8.

[0055] Rack teeth 3 are connected in rotation in rack box 2, refer to Figure 8 , the rack teeth 3 can only rotate counterclockwise into the rack box 2. When it rotates clockwise, the rack teeth 3 will be restricted to the following positions: Figure 8 The position of the gear 31 and the rack teeth 3 are meshed with each other when the door panel of the device is closed. Since the door panel 4 is in an open state when it moves from one end of the No. 1 mounting block 9 to one end of the push rod 5, the gear 31 is meshed with the rack teeth 3. The gear 31 rotates clockwise under the action of the rack teeth 3. When the gear 31 rotates clockwise, it drives the synchronous shaft 43 to rotate, and the synchronous shaft 43 drives the spring 39 to store power. Figure 5 The relative position of the middle gear 31 and the check block 35 and the inclined surface at the front end of the check block 35, when the gear 31 rotates clockwise, the teeth of the gear 31 will contact the inclined surface at the front end of the check block 35, and press the check block 35 into the inside of the door panel 4, under the action of the check spring 36, the check block 35 will reset, because the spring 39 will release its accumulated energy, the gear 31 will rotate counterclockwise, when the gear 31 starts to rotate counterclockwise, the teeth of the gear 31 will contact the lower surface of the check block 35, because the lower surface of the check block 35 is a plane, so when the position of the check block 35 is located as shown in the figure, the check block 35 will be pressed into the door panel 4. Figure 5 When the gear 31 is in the state of rotating counterclockwise, the mainspring 39 can only store energy but cannot release energy.

[0056] For further reference, Fig.13 There are several friction blocks 38, and they are all fixedly connected to the door panel 4. The friction blocks 38 are made of rubber anti-skid material. The degree of power storage of the spring 39 is limited. When the power storage reaches the maximum limit, if it is further stored, there is a risk of damage. However, since the friction block 38 fits with one end of the spring 39, Fig.13There will be a certain friction between the friction block 38 and the mainspring 39. When the mainspring 39 accumulates force to the maximum extent and is still accumulating force, the end of the mainspring 39 that is in contact with the friction block 38 will be out of contact and be in contact with the next friction block 38. It can be understood that the displacement of the end of the mainspring 39 that is in contact with the friction block 38 is used to release part of the energy to prevent damage to the mainspring 39.

[0057] Furthermore, when a fire occurs outside, the temperature outside will rise, and the glass tube 33 is filled with a thermosensitive liquid, which will expand due to the heat and burst the glass tube 33. At this time, the glass tube 33 will release the limit on the alarm spring rod 32, and then the output rod of the alarm spring rod 32 will drive the pull rod 34 to move toward the direction of the No. 1 mounting block 9. Fig.14 At this time, the check block 35 will be pulled by the pull rod 34, which will release the limit on the gear 31 by the check block 35. After the limit is released, the spring 39 can release energy. At this time, the spring 39 will make the gear 31 rotate counterclockwise, and finally drive the knocking rod 44 to rotate and make the impact block 6 hit the hollow shell. During the rotation, since the impact block 6 and the knocking rod 44 are in sliding connection, the impact block 6 will slide out of the knocking rod 44 under the action of centrifugal force.

[0058] Furthermore, when the connecting pin 29 of the device is taken away by the user, the device is locked by default. At this time, if a stranger tries to pry the door, he can only start from the handle 25 and the connecting plate 8. If the stranger starts from the handle 25, although he can press the rotating shaft 30 with tools such as an extension rod to release the limit of the pressure plate 26 on the connecting plate 8, the stranger is limited by the fact that he does not have the detailed size and structure of the connecting pin 29, and the structure of the extension rod cannot be the same as that of the connecting pin 29, so the extension rod cannot rotate the rotating shaft 30 to open the door panel 4. In addition, when the stranger measures the end of the rotating shaft 30 close to the handle 25 in an attempt to obtain the detailed structure and size of the connecting pin 29, it will be difficult to do so because the internal space of the handle 25 is too small.

[0059] Furthermore, when a stranger attempts to pry the door open with respect to the connecting plate 8, the connecting plate 8 can only be pushed upwards by means of the sheet-like plate. Then, the sheet-like plate needs to pass through the door gap and be lifted upwards, at which time the slide plate 42 will be triggered. Fig.13 , Fig.14 , Fig.15 , Fig.16 At this time, the slide plate 42 will be lifted upward, and finally the check block 35 will slide into the door panel 4 by the joint action of the No. 1 wire wheel 40, the No. 2 wire wheel 41 and the wire rope 37. Since the check block 35 cancels the limit on the gear 31 at this time, the mainspring 39 can release the energy accumulated before, so that the gear 31 rotates, and drives the knocking rod 44 and the impact block 6 to impact the hollow shell 45, generating a sound, thereby reminding the user of the device.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
