Description

Technical Field

[0001] The present invention relates to the technical field of electronic locks, and in particular to an elastic contact power supply device for reciprocating motion of a latch bolt. Background Art

[0002] The full name of a security door is "anti-theft safety door." It combines both theft prevention and security features. According to the "General Technical Requirements for Security Doors," a qualified security door must be impossible to pry open or create a 615 square centimeter opening in the door leaf within 15 minutes using common hand tools like chisels, screwdrivers, and crowbars, or portable power tools like electric drills. Alternatively, a 38 square millimeter opening can be opened within a 150 square millimeter semicircle around the locking point. Furthermore, the locks used on security doors must be special locks with drill-resistant features that have been tested and approved by the Ministry of Public Security's Testing Center. Security doors can be made of a variety of materials, but only doors that meet standard testing standards and receive a production license for security products can be considered security doors.

[0003] At present, ordinary security doors are usually installed with mechanical locks. When users need to use smart products, such as electronic locks, they need to replace the entire security door, which is not only time-consuming and labor-intensive, but also increases family costs. In addition, some security doors on the market are equipped with smart products, such as electronic locks, alarms, monitoring, etc. These common security doors with smart products usually need to be powered by batteries, and multiple ordinary batteries are needed for power supply. Since the smart products on the security doors consume a lot of power, ordinary batteries need to be replaced after a short service life, and basically need to be replaced between half a month and a month. The more smart products are installed, the more batteries are consumed. The defect of this type of security door with smart products is that it cannot achieve long-term power supply and can only rely on batteries. Frequent battery replacement or charging is not only time-consuming and labor-intensive, but also increases family living costs. In an emergency, the battery is exhausted and the door cannot be opened, which is likely to cause more trouble, and the actual application effect is not ideal. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings:

[0033] Referring to the accompanying drawings: the elastic contact power supply device for the reciprocating motion of the inclined bolt in this embodiment includes a door frame 1, a door leaf 2 is connected to the door frame 1, a reset device 3 is installed on the door frame 1, and a conductive device 4 is installed on the door leaf 2. The conductive device 4 is connected to the reset device 3 and energized when the door leaf 2 is closed, and is disconnected from the reset device 3 and de-energized when the door leaf 2 is opened;

[0034] The reset device 3 includes a housing 5, in which an oblique tongue 6 is provided. The inner end of the oblique tongue 6 is provided with a lever 7, which is provided in the housing 5. When the oblique tongue 6 retracts, the lever 7 is driven to rotate. One end of the lever 7 is located at the inner end of the oblique tongue 6, and the other end of the lever 7 is provided with a ball column 18 and a ball column 2 9. When the lever 7 rotates, the ball columns 18 and 9 are driven to move synchronously. The output end of the ball column 8 is connected to a conductive column 10, and the conductive column 10 is provided with a positive wire terminal 11 wrapped around the outer surface of the conductive column 10. The output end of the ball column 2 9 is connected to a conductive column 2 12, and the conductive column 2 12 is provided with a negative wire terminal 13 wrapped around the conductive column 2 12. The ball columns 18, 9, conductive columns 10, and conductive columns 2 12 are all provided on the housing 5;

[0035] The conductive device 4 includes a shell 2 14, on which a positive contact 15 and a negative contact 16 are provided. The positive contact 15 is connected to a positive terminal 17, and the negative contact 16 is connected to a negative terminal 18. The positive terminal 17 and the negative terminal 18 are both provided on the shell 2 14. The positive contact 15 contacts the conductive column 10 when the door leaf 2 is closed, and the positive contact 15 is separated from the conductive column 10 when the door leaf 2 is opened. The negative contact 16 contacts the conductive column 2 12 when the door leaf 2 is closed, and the negative contact 16 is separated from the conductive column 2 12 when the door leaf 2 is opened.

[0036] Such a configuration is shown in the figure. The door frame 1 and the door leaf 2 are connected by conventional hinges 101. The door frame 1 is installed with a reset device 3. The door leaf 2 is installed with a conductive device 4 and a smart product 102. The smart product 102 includes an electronic lock and may also include a buzzer, a monitor, etc. It can be applied to a smart product on an anti-theft door. The mains 103 is connected to the reset device 3 through a power adapter 104 to supply power to the positive terminal 11 and the negative terminal 13. The positive terminal 17 and the negative terminal 18 of the conductive device 4 are electrically connected to the smart product 10. 2 power supply, when the door leaf 2 is closed, the inclined tongue 6 retracts into the shell 1 5 under the action of the door leaf 2, and the retraction of the inclined tongue 6 drives the lever 7 to rotate, and the rotation of the lever 7 drives the ball column 1 8 and the ball column 2 9 to move outward at the same time, the outward movement of the ball column 1 8 pushes the conductive column 1 10 to move outward, and the outward movement of the ball column 2 9 pushes the conductive column 2 12 to move outward, and the conductive column 10 moves outward to the positive contact 15. At this time, the conductive column 10 contacts the positive contact 15, and the conductive column 2 12 moves outward to the negative contact 16. At this time, the conductive column 2 12 contacts the negative contact 1 6 contact, since the conductive column 10 is connected to the positive wire terminal 11, at this time, the positive wire terminal 11 is electrically connected to the positive contact 15, since the conductive column 2 is connected to the negative wire terminal 13, at this time, the negative wire terminal 13 is electrically connected to the negative contact 16. At this time, the mains 103 supplies power to the smart product 102 through the power adapter 104, the positive wire terminal 11, the negative wire terminal 13, the positive contact 15, the negative contact 16, the positive electron 17, and the negative terminal 18. When the door leaf 2 is closed, the mains 103 is reset through the reset device 3. The conductive device 4 supplies power to the smart product 102 to achieve long-term power supply effect. No batteries are needed, which eliminates the need for batteries and the trouble of replacing batteries, saves time and effort, and reduces family living costs. When the door leaf 2 is opened, the conductive device 4 leaves the reset device 3, the positive contact 15 leaves the conductive column 10, and the negative contact 16 leaves the conductive column 2 12. At this time, the circuit is disconnected to achieve power-off effect, which avoids accidental contact on the one hand and reduces electricity costs on the other hand. The power supply voltage of the smart product 102 is a safe voltage of 3V-24V.

[0037] A spring 19 is sleeved on the ball column 8, and the spring 19 is connected between the ball column 8 and the conductive column 10. A spring 20 is provided between the conductive column 10 and the positive line terminal 11, and the spring 20 is sleeved on the conductive column 10.

[0038] In this arrangement, spring 19 is connected to the end of ball column 18, and then connected to the conductive column 10. The conductive column 10 has a groove, and spring 19 is installed in the groove. When the door leaf 2 is closed, ball column 18 squeezes and moves spring 19 in the groove, causing the conductive column 10 to move outward and stop after contacting the positive contact 15 to power the door. The spring 19 is in a compressed state. When the door leaf 2 is opened, the positive contact 15 leaves the conductive column 10, and the spring 19 is released and naturally rebounds, causing the ball column 8 to rebound and reset, driving the lever 7 to reset, and the cross-section of the conductive column 10 is T-shaped. The positive terminal 11 is sleeved on the outer surface of the end of the conductive column 10, and the spring 20 is sleeved on the conductive column 10 and is pressed tightly by the top of the conductive column 10 and the positive terminal 11. When the conductive column 10 moves outward, the spring 20 presses the positive terminal 11 against the conductive column 10 under the action of the top of the conductive column 10 to prevent the positive terminal 11 from moving, ensuring good contact between the positive terminal 11 and the conductive column 1, avoiding poor contact and ensuring normal power supply. After the positive contact 15 leaves the conductive column 10, the spring 20 releases to reset the conductive column 10.

[0039] A spring three 21 is sleeved on the second ball column 9 , and the spring three 21 is connected between the second ball column 9 and the second conductive column 12 . A spring four 22 is provided between the second conductive column 12 and the negative terminal 13 , and the spring four 22 is sleeved on the second conductive column 12 .

[0040] In this way, spring three 21 is connected to the end of ball column two 9, and then connected to the conductive column two 12. There is a groove in the conductive column two 12, and spring three 21 is installed in the groove. When the door leaf 2 is closed, ball column two 9 squeezes and moves spring three 21 in the groove, causing the conductive column two 12 to move outward and stop after contacting the negative contact 16 to power supply. Spring three 21 is in a compressed state. When the door leaf 2 is opened, the negative contact 16 leaves the conductive column two 12, and the spring three 21 is released and rebounds naturally, causing ball column two 9 to rebound and reset, driving lever 7 to reset, and the cross-section of the conductive column two 12 is T-shaped. The negative terminal 13 is sleeved on the outer surface of the end of the conductive column 2 12, and the spring 4 22 is sleeved on the conductive column 2 12 and is pressed by the top of the conductive column 2 12 and the negative terminal 13. When the conductive column 2 12 moves outward, the spring 4 22 presses the negative terminal 13 on the conductive column 2 12 under the action of the top of the conductive column 2 12, preventing the negative terminal 13 from moving, ensuring good contact between the negative terminal 13 and the conductive column 2 12, avoiding poor contact, and ensuring normal power supply. After the negative contact 16 leaves the conductive column 2 12, the spring 4 22 releases to reset the conductive column 2 12.

[0041] The positive wire terminal 11 is connected to a positive wire 23 , which is set on the shell 15 . The negative wire terminal 13 is connected to a negative wire 24 , which is set on the shell 15 . A wire rack 25 is set on the shell 15 , and both the positive wire 23 and the negative wire 24 are set on the wire rack 25 .

[0042] In this arrangement, the positive wire terminal 11 is connected to the positive wire 23, and the negative wire terminal 13 is connected to the negative wire 24. The positive wire 23 and the negative wire 24 are connected to the power adapter 104, so that the AC power 103 can power the positive wire terminal 11 and the negative wire terminal 13, forming a power-on effect. The wire rack 25 is used to install the positive wire 23 and the negative wire 24, fix the positive wire 23 and the negative wire 24, so that the positive wire 23 and the negative wire 24 do not interfere with the lever 7, ensuring the normal use of the positive wire 23 and the negative wire 24.

[0043] The lever 7 is mounted in the housing 5 via a pin 26. With this arrangement, the lever 7 can rotate in the housing 5 via the pin 26.

[0044] The inclined tongue 6 is installed in the housing 1 5 through the pin 2 27. In this way, the inclined tongue 6 can be installed in the housing 1 5 through the pin 27.

[0045] The positive terminal 17 is connected to the positive contact 15 by a screw 28, and the screw 28 is arranged in the housing 14. This arrangement has a good fixing effect.

[0046] The negative terminal 18 is connected to the negative contact 16 by a second screw 29, which is arranged in the second housing 14. This arrangement has a good fixing effect.

[0047] Gaskets 30 are provided outside the conductive pillars 10 and 12, and are disposed within the housing 1 5. With this arrangement, the gaskets 30 block the conductive pillars 10 and 12 on both sides, preventing them from falling out and ensuring their normal operation.

[0048] The gasket 30 is installed in the housing 1 5 by screw 31 .

[0049] like Figure 9 As shown in the figure, it is a schematic diagram of the conductive column 1 contacting the positive contact when the door leaf is closed. The conductive column 1 contacts the positive contact and the conductive column 2 contacts the negative contact. The two work at the same time. Therefore, the principle of the conductive column 2 contacting the negative contact is the same. Figure 9 You can find out, so I won’t go into details.

[0050] like Figure 10As shown in the figure, it is a schematic diagram of the conductive column 1 leaving the positive contact when the door leaf opens. When the conductive column 1 leaves the positive contact, the conductive column 2 leaves the negative contact at the same time. The two work at the same time. Therefore, the principle of the conductive column 2 leaving the negative contact is the same. Figure 10 You can find out, so I won’t go into details.

[0051] The embodiment of the present invention is characterized by the following advantages:

[0052] 1. It can be installed on existing ordinary security doors and provide power for them. When users need to install smart products on ordinary security doors, they can realize the power supply function, turning ordinary security doors into smart doors. There is no need to replace security doors to realize the use of smart doors, which reduces the user's family living costs.

[0053] Second, it can be installed on the security door to provide long-term power for the smart products on the security door.
