Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm, in particular to a wiring structure of automatic fire alarm equipment. Background Art

[0002] The automatic fire alarm system is a key safety device used to detect and report fire incidents early so that necessary emergency measures can be taken. The wiring structure, as the basic component of the system, is responsible for connecting fire detectors, fire alarm control panels and other alarm devices to achieve signal transmission and linkage control.

[0003] The existing automatic fire alarm generally has two metal contacts crimped by screws on the base, and then the two metal contacts at the bottom of the main unit are symmetrically arranged. The symmetrical metal contacts are connected by installing the main unit and the base. When crimping the wires by bolts, the bolts need to be tightened one by one to compress the wiring, which is more troublesome. Moreover, the wiring is easily worn and damaged after being used for a long time after compression, which affects the connection of the wiring. When the base and the main unit are installed, they are generally installed by threaded connection or rotating the main unit to drive the card block to be clamped on the base. Since the base is installed on the ceiling, it is necessary to raise the head and support the installation with the arm when installing the main unit. It takes more force to connect by thread or rotation, which is inconvenient to install. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wiring structure for an automatic fire alarm device, which is easy to install and can also prevent the wiring from being squeezed and damaged.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A wiring structure of an automatic fire alarm device comprises a host and a base, wherein a support plate is fixedly connected to the middle inner wall of the base, a threaded rod is fixedly connected to the top of the support plate, a round sleeve is slidably connected to the outer wall of the threaded rod, a limiting sleeve is rotatably connected to the top of the round sleeve, a pressure plate is fixedly connected to the outer wall of the round sleeve, a rubber pad is fixedly connected to the bottom end of the pressure plate, a first metal contact is fixedly connected to the bottom inner wall of the base, a second metal contact is fixedly connected to the bottom end of the host, a card block is penetrated and slidably connected to the bottom end of the host, and a card slot is provided on the left inner wall of the base.

[0007] Preferably, a slider penetrates and is slidably connected to the left side of the host, the clamping block is elastically connected to the host via a spring, and a second metal contact is fixedly connected to the bottom end of the host.

[0008] Preferably, the limiting sleeve is threadedly connected to the threaded rod, and the rubber pad is in contact with the first metal contact.

[0009] Preferably, the clamping block is fixedly connected to the right side of the slider, and the second metal contact is in contact with the first metal contact.

[0010] Preferably, the left side of the block is arranged as an inclined surface.

[0011] Preferably, the left side of the card block is adapted to the size of the card slot, and the host is in contact with the base.

[0012] Preferably, one end of the spring is fixedly connected to the right side of the block, and the other end of the spring is fixedly connected to the inner wall of the bottom end of the host.

[0013] Preferably, the second metal contact, the pressure plate, the rubber pad and the first metal contact are provided in multiple groups, and the multiple groups of the second metal contact, the pressure plate, the rubber pad and the first metal contact are symmetrically arranged with the center line of the base as the axis of symmetry.

[0014] The utility model has the following beneficial effects:

[0015] (1) When the wiring structure of the automatic fire alarm device is in use, the wire is placed on the top of the first metal contact, and the round sleeve is moved downward so that the rubber pad and the pressure plate squeeze the wire. At the same time, the limiting sleeve is threadedly connected to the threaded rod, so that the round sleeve, the pressure plate, and the rubber pad cooperate to compress the wire at the same time, without the need to tighten the wires one by one with bolts. At the same time, the rubber pad can prevent the wires from being squeezed and damaged by the bolts and the second metal contact point.

[0016] (2) When the wiring structure of the automatic fire alarm device is in use, the base squeezes the inclined surface of the card block when the host moves downward, causing the card block to move to the right to squeeze the spring. At the same time, after the host moves downward and contacts the top of the base, the reverse force of the squeezed spring causes the card block to reset and slide into the card slot to limit the host. There is no need to rotate and spend more force. When installing on the ceiling, it only needs to be pressed upward to install, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a wiring structure of an automatic fire alarm device, including a host 1 and a base 3. The host 1 and the base 3 are installed on the ceiling to detect and report fire. A support plate 10 is fixedly connected to the inner wall of the middle part of the base 3. The support plate 10 supports a threaded rod 9. The top of the support plate 10 is fixedly connected to the threaded rod 9. The threaded rod 9 cooperates with a round sleeve 7 and a limit sleeve 8 to press the wiring. The outer wall of the threaded rod 9 is slidably connected to the round sleeve 7.

[0023] The round sleeve 7 supports the limiting sleeve 8 and the pressing plate 12. The top of the round sleeve 7 is rotatably connected to the limiting sleeve 8. The limiting sleeve 8 can be threadedly connected with the threaded rod 9 to limit the round sleeve 7. The outer wall of the round sleeve 7 is fixedly connected with the pressing plate 12. The pressing plate 12 supports the rubber pad 11 and compresses the wiring by squeezing the rubber pad 11 through the pressing plate 12. The bottom end of the pressing plate 12 is fixedly connected with the rubber pad 11. The rubber pad 11 squeezes the wiring to reduce friction damage of the wiring and increase the service life of the wiring.

[0024] The inner wall of the bottom end of the base 3 is fixedly connected with a first metal contact 13. After the second metal contact 14 contacts the first metal contact 13, the host 1 can be connected to the wiring to realize the detection and reporting of the fire.

[0025] Further, the bottom end of the host 1 is fixedly connected with a second metal contact 14, and the second metal contact 14 is symmetrical with the first metal contact 13. The bottom end of the host 1 is penetrated and slidably connected with a card block 5, and the card block 5 slides into the card slot 6 to limit the host 1. The left inner wall of the base 3 is provided with a card slot 6, and the card slot 6 cooperates with the card block 5 to connect the host 1 with the base 3; the left side of the host 1 is penetrated and slidably connected with a slider 2, and when repairing or dismantling, pressing the slider 2 can make the card block 5 slide out of the card slot 6 to release the limit of the host 1, and the card block 5 is elastically connected to the host 1 through the spring 4;

[0026] When the host 1 is installed, the block 5 is driven to squeeze the base 3, and at the same time, the base 3 squeezes the inclined surface of the block 5 so that the block 5 squeezes the spring 4. When the block 5 is aligned with the slot 6, the reverse force of the squeezed spring 4 can make the block 5 reset and slide into the slot 6 to limit the host 1. The bottom end of the host 1 is fixedly connected with the second metal contact 14. After the second metal contact 14 contacts the first metal contact 13, the host 1 is connected to the wiring. The limiting sleeve 8 is threadedly connected to the threaded rod 9. The limiting sleeve 8 and the threaded rod 9 can cooperate to limit the round sleeve 7 and tighten the wiring at the same time.

[0027] Further, the rubber pad 11 contacts the first metal contact 13, and the rubber pad 11 squeezes the wiring so that the wiring contacts the first metal contact 13. The card block 5 is fixedly connected to the right side of the slider 2, and the slider 2 can drive the card block 5 to move. The second metal contact 14 contacts the first metal contact 13. At this time, the host 1 is connected to the wiring. The left side of the card block 5 is set as an inclined surface. By setting the left side of the card block 5 as an inclined surface, when installing the host 1, the host 1 can be directly pressed so that the base 3 squeezes the inclined surface of the card block 5, and then the left side of the card block 5 slides into the card slot 6 through the cooperation of the spring 4. At this time, the host 1 is limited and installed;

[0028] The left side of the card block 5 is adapted to the size of the card slot 6, the host 1 is in contact with the base 3, one end of the spring 4 is fixedly connected to the right side of the card block 5, and the other end of the spring 4 is fixedly connected to the inner wall of the bottom end of the host 1, and multiple groups of second metal contacts 14, pressure plates 12, rubber pads 11, and first metal contacts 13 are arranged, and the multiple groups of second metal contacts 14, pressure plates 12, rubber pads 11, and first metal contacts 13 are symmetrically arranged with the center line of the base 3 as the symmetry axis.

[0029] In the present invention, when in use, the base 3 is first placed on the ceiling so that the bottom end of the base 3 contacts the ceiling, and after the base 3 is fixedly installed on the ceiling, the wiring is passed through the middle inner wall of the base 3, and two wirings are respectively placed on the top ends of the multiple groups of first metal contacts 13, and then the round sleeve 7 is sleeved on the outer wall of the threaded rod 9, and then the limiting sleeve 8 is rotated, and the limiting sleeve 8 is threadedly connected with the threaded rod 9 so that the round sleeve 7 moves downward to contact the wiring, and the limiting sleeve 8 is continued to be rotated so that the pressure plate 12 and the rubber pad 11 cooperate to press the wiring, and at the same time, the round sleeve 7 is pressed by the limiting sleeve 8. At this time, the wiring connection is completed, and there is no need to install the wiring one by one;

[0030] At the same time, the rubber pad 11 is used to prevent the wiring from directly contacting the metal and being pressed, thereby improving the service life of the wiring. Then, after the block 5 on the host 1 is aligned with the slot 6, the host 1 is moved downward to drive the block 5 to move downward, so that after the block 5 contacts the top of the base 3, it continues to move so that the base 3 squeezes the block 5. The left side of the block 5 is set as an inclined surface, so that the block 5 moves to the right to squeeze the spring 4. When the block 5 moves to the right, the host 1 can continue to move. When the host 1 contacts the top of the base 3, the reverse force of the spring 4 being squeezed makes the block 5 reset to the left and slide into the slot 6 to get stuck. At this time, the host 1 is limited. At this time, the host 1 and the base 3 are installed. It is more convenient to install without rotating the host 1. When it needs to be removed, it is more convenient to remove the host 1 by simply pressing the slider 2 inward to make the block 5 slide out of the slot 6.
