During on-site installation, bolts are used to fix it on a fixed support surface (such as a wall and the like), and then several connection ends of the controller on the safety monitoring device are respectively connected to the operating equipment. Thus, continuous safety monitoring of the operating equipment is carried out.

[0004] Although this method can effectively perform safety monitoring on the operating equipment, when a part of the safety monitoring device is damaged and needs to be disassembled for replacement or repair, the entire safety monitoring device needs to be disassembled from the fixed support surface (such as a wall and the like), which is inconvenient to operate. Summary of the Invention

[0005] To overcome at least one or more of the above-mentioned defects in the prior art, a first aspect of the present invention provides a fixing device for an alarm controller, including an installation box body for installing the alarm controller and a fixing mechanism for fixing on a fixed support surface.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to better understand the purpose, structure and function of the present invention, the present invention will be further described in detail below with reference to the drawings for an alarm control device.

[0027] For convenience, the direction along the sliding column is referred to as "lateral", "horizontal direction" or similar terms, the direction perpendicular to the "lateral" is referred to as "vertical", "perpendicular direction" or similar terms, the movement along the "lateral" is referred to as "horizontal movement", "lateral movement" or similar terms, and the movement along the "perpendicular direction" is referred to as "vertical movement", "up and down movement" or similar terms.

[0028] According to an embodiment of the present invention, as Figure 1 shown, the alarm control device 100 includes a controller 1 for continuously monitoring an operating object, a mounting box body 2 connected to the controller 1, and a fixing mechanism 3 detachably connected to the mounting box body 2. Among them, the free end of the fixing mechanism 3 is used for fixedly connecting to a fixed support surface. In the context of the present invention, the fixed support surface refers to the surface for mounting the alarm control device 100, such as a wall surface and the like.

[0029] Meanwhile, the controller 1 is configured to have a plurality of connection ends (not shown in the figure), each of the connection ends is connected to an operating object, and each of the connection ends is used for continuously monitoring and controlling the operating object. In this way, continuous safety monitoring of the operating object is performed.

[0030] In this way, the controller 1, the mounting box body 2, and the fixing mechanism 3 are interconnected to form an integral structure. At the same time, the alarm control device 100 is arranged on a fixed support surface (wall surface and the like) through the fixing mechanism 3, and the controller 1 is respectively connected to a plurality of operating objects for continuously monitoring the operating objects.

[0031] In an embodiment, as Figure 1 shown, the mounting box body 2 is set in any shape convenient for connecting to the fixing mechanism 3. In this embodiment, the mounting box body 2 is set in a hollow square structure. Among them, the fixing mechanism 3 is set to at least one and is located on the side surface of the mounting box body 2. In this embodiment, the fixing mechanism 3 is set to two, and is respectively arranged on both sides of the mounting box body 2 in a symmetrical manner. In this way, the mounting box body 2 can be stably connected to the fixing mechanism 3.

[0032] In an embodiment, as Figure 1 shown, at least one first through hole 21 extending in the horizontal direction is provided on the mounting box body 2, and at least one second through hole 311 corresponding to the first through hole 21 is provided on the fixing mechanism 3. In this embodiment, two second through holes 311 are provided on the fixing mechanisms 3 located on both sides of the mounting box body 2. At the same time, the first through holes 21 located on the mounting box body 2 are correspondingly arranged with the second through holes 311. Specifically, the first through hole 21 and the second through hole 311 are docked with each other, and are respectively set to four, and are distributed on both sides of the mounting box body 2 in a pairwise opposite manner.

[0033] In an embodiment, as Figure 2As shown, a limiting mechanism 4 for inserting into the first through hole 21 and the second through hole 311 is provided inside the installation box body 2. The limiting mechanism 4 is provided in four, and is respectively arranged in a manner corresponding to the above-mentioned first through hole 21. At the same time, a driving mechanism 5 for pushing the limiting mechanism 4 to move horizontally is provided on the limiting mechanism 4. Thus, the installation box body 2 and the fixing mechanism 3 can be connected in an adjustable manner.

[0034] In one embodiment, as Figure 3 shown, the limiting mechanism 4 includes a sliding column 41. The sliding column 41 is arranged in any structure convenient for inserting into the first through hole 21 and the second through hole 311. In this embodiment, the sliding column 41 is arranged in a structure adapted to the first through hole 21 and the second through hole 311. The limiting mechanism 4 further includes a thrust bearing platform 42 provided inside each sliding column 41. In this embodiment, the thrust bearing platform 42 is arranged in a structure integrated with the sliding column 41. Thus, the sliding column 41 can move synchronously with the thrust bearing platform 42.

[0035] In one embodiment, as Figure 2 shown, the driving mechanism 5 includes a pushing portion 51 for pushing the thrust bearing platform 42 to move horizontally and fitting with the thrust bearing platform 42. Among them, the surface of the thrust bearing platform 42 in contact with the pushing portion 51 is arranged as a first inclined surface, and the surface of the pushing portion 51 in contact with the thrust bearing platform 42 is arranged as a second inclined surface. In this embodiment, the vertical height of the first inclined surface is not less than the length of the sliding column 41. At the same time, an elastic member 6 with both ends respectively abutting against the thrust bearing platform 42 and the installation box body 2 is sleeved on the sliding column 41.

[0036] In this way, when the pushing portion 51 moves vertically, it can drive the second inclined surface to move synchronously with the pushing portion 51. During this process, the area of mutual contact between the first inclined surface and the second inclined surface will continuously change. When the area of contact between the first inclined surface and the second inclined surface gradually decreases, the pushing portion 51 will continuously push the thrust bearing platform 42 to move along the position close to the first through hole 21.

[0037] During this process, the thrust bearing platform 42 will continuously compress the elastic member 6 to cause elastic deformation, thereby promoting the sliding column 41 to move closer to the first through hole 21 until the sliding column 41 enters the first through hole 21 and the second through hole 311. After the sliding column 41 is located in the first through hole 21 and the second through hole 311, by continuously limiting the thrust bearing platform 41 by the pushing portion 51, the elastic member 6 is prevented from restoring elastic deformation. Thus, the installation box body 2 and the fixing mechanism 3 are connected.

[0038] When the area of the fit between the first inclined surface and the second inclined surface gradually increases, the pushing part 51 will gradually cancel the limit on the thrust-bearing platform 42. During this process, the elastic member 6 will continuously recover its elastic deformation, thereby continuously pushing the thrust-bearing platform 42 to move away from the position of the first through-hole 21 through the elastic member 6, and promoting the sliding column 41 to move synchronously with the thrust-bearing platform 42 until the sliding column 41 disengages from the second through-hole 311. Thus, the installation box body 2 is separated from the fixing mechanism 3, and the installation box body 2 is detached from the fixing mechanism 3.

[0039] According to a preferred embodiment of the present invention, as Figure 2 shown, the thrust-bearing platform 42 is arranged in a square block structure. Among them, the horizontal distance between the upper end of the first inclined surface located on the thrust-bearing platform 42 and the side wall of the installation box body 2 is greater than the horizontal distance between the lower end of the first inclined surface and the side wall of the installation box body 2. At the same time, the pushing part 51 is arranged in a square block structure adapted to the thrust-bearing platform 42. Among them, the horizontal distance between the upper end of the second inclined surface located on the pushing part 51 and the side wall of the installation box body 2 is greater than the horizontal distance between the lower end of the first inclined surface and the side wall of the installation box body 2.

[0040] In this setting method, when the pushing part 51 moves vertically upward, it can continuously push the thrust-bearing platform 42 to move closer to the first through-hole 21 and limit the thrust-bearing platform 42. When the pushing part 51 moves vertically downward, the limit on the thrust-bearing platform 42 can be gradually cancelled, so that the thrust-bearing platform 41 moves away from the first through-hole 21 through the elastic deformation recovery of the elastic member 6.

[0041] In an embodiment, as Figure 2 shown, the driving mechanism 5 further includes a fixing frame 52 for connecting the four pushing parts 51, so that an integral structure can be formed between the four pushing parts 51 and the fixing frame 52. In this way, during the movement of the fixing frame 52, it can drive the four pushing parts 51 to move synchronously, thereby pushing the four thrust-bearing platforms 42 to move synchronously.

[0042] In an embodiment, as Figure 2 shown, the fixing frame 52 includes connecting rods 521 fixedly connected to the pushing parts 51, and two connecting rods 521 are provided. Among them, the two connecting rods 521 are symmetrically arranged and are respectively used to connect the two pushing parts 51 on one side of the installation box body 2. At the same time, the fixing frame 52 further includes a movable rod 522 for connecting the two connecting rods 521. Specifically, in this setting method, an integral structure in the shape of "H" can be jointly formed between the two connecting rods 521 and the movable rod 522. In this way, the connecting rods 521 can be driven to move synchronously during the movement of the movable rod 522.

[0043] In this setting mode, during use, when the movable rod 522 moves vertically upward, the movable rod 522, the two connecting rods 521, and the pushing part 51 can move upward synchronously. During this process, each pushing part 51 can push the bearing platform 42 arranged in contact with the pushing part 51 to move laterally, thereby compressing the elastic member 6 located on the outer periphery of the sliding column 41 to undergo elastic deformation and actuating the sliding column 41 to move laterally until the sliding column 41 is inserted into the first through hole 21 and the second through hole 311, and the pushing part 51 continuously limits the bearing platform 42. Thus, the installation box body 2 and the fixing mechanism 3 are connected.

[0044] When the movable rod 522 moves vertically downward, the movable rod 522, the two connecting rods 521, and the pushing part 51 can move downward synchronously. During this process, the pushing part 51 will gradually cancel the limit on the bearing platform 42. At this time, the elastic member 6 located on the outer periphery of the sliding column 41 will gradually recover its elastic deformation until the sliding column 41 is disengaged from the second through hole 311. Thus, the installation box body 2 and the fixing mechanism 3 are disengaged, and the installation box body 2 is detached from the fixing mechanism 3.

[0045] According to a preferred embodiment of the present invention, as Figure 2 shown, the fixing frame 52 formed jointly between the two connecting rods 521 and the movable rod 522 is vertically arranged in an "H" shape. Specifically, the connecting rod 521 extends horizontally.

[0046] In one embodiment, as Figure 2 shown, a driving part 53 for driving the fixing frame 52 to move vertically is arranged on the fixing frame 52. In this embodiment, the driving part 53 is connected to the movable rod 522. Among them, the driving part 53 includes a threaded hole (not shown in the figure) opened on the movable rod 522, and a threaded rod 531 that passes through the threaded hole and extends vertically and is engaged with the thread on the threaded hole. One end of the threaded rod 531 extends to the installation box body 2 and is rotatably connected to the installation box body 2, and the other end penetrates the wall surface of the installation box body 2 and extends outside the installation box body 2 to form a force application end.

[0047] In this way, when the threaded rod 531 rotates, the threaded hole can continuously engage with the thread on the surface of the threaded rod 531. Thus, the movable rod 522 can be driven to move up and down, so that the entire fixing frame 52 moves synchronously.

[0048] In one embodiment, as Figure 2As shown, on the upper and lower sides of the movable rod 522 inside the installation box body 2, limiting bosses 22 are respectively arranged. One end of the limiting boss 22 is fixedly arranged on the inner wall of the installation box body 2, and the other end extends out to form an interference with the movable rod 522. At the same time, the relative distance between the upper and lower surfaces of the movable rod 522 and the upper and lower limiting bosses 22 is equivalent to the vertical distance of the first inclined surface. In this way, the movable rod 522 can only move between the upper and lower limiting bosses 22, thereby preventing the pushing part 51 from being separated from the bearing platform 42 vertically.

[0049] According to a preferred embodiment of the present invention, as Figure 2 shown, a guide rod 532 is inserted through one side of the movable rod 522 where the threaded rod 531 is located, and both ends of the guide rod 532 extend to the installation box body 2 respectively. In this way, during the up and down displacement of the movable rod 522, it can move along the path formed by the guide rod 532, thereby preventing the pushing part 51 from being separated from the bearing platform 42 axially.

[0050] In this setting mode, during use, rotate the force application end of the threaded rod 531 outside the installation box body 2 to make the threaded rod 531 rotate. During the rotation of the threaded rod 531, the thread on the surface of the threaded rod 531 can continuously engage with the thread on the threaded hole (not shown in the figure) on the movable rod 522.

[0051] During this process, the movable rod 522 will continuously move vertically along the path formed by the guide rod 532 as the threaded rod 531 rotates. Thus, the pushing part 51 can continuously push the bearing platform 42 to move horizontally and limit the bearing platform 42, or gradually cancel the limit of the pushing part 51 on the bearing platform 42.

[0052] During the continuous vertical movement of the pushing part 51, when the lower end of the second inclined surface on the pushing part 51 contacts the upper end of the first inclined surface, it will be limited by the limiting boss 22 above the movable rod 522. When the upper end of the second inclined surface on the pushing part 51 contacts the lower end of the first inclined surface, it will be limited by the limiting boss 22 below the movable rod 522. Thus, it can prevent the pushing part 51 from being separated from the bearing platform 42 during the continuous displacement of the movable rod 522.

[0053] According to a preferred embodiment of the present invention, as Figure 2 shown, a handle 533 is arranged on the force application end of the threaded rod 531 outside the installation box body 1, and the handle 533 can provide a fulcrum for the force on the threaded rod 531, which is convenient for the application of the force.

[0054] According to a preferred embodiment of the present invention, as Figure 1As shown, the device 100 further includes an alarm mechanism 7. The alarm mechanism 7 includes a connecting column 71 with one end disposed on the movable rod 522, and an acoustic-optic alarm 72 disposed at the free end of the connecting column 71. Meanwhile, a passage for the acoustic-optic alarm to pass through is provided on the mounting box body 2. In this way, during the movement of the movable rod 522, the acoustic-optic alarm 72 can be driven to move outside the mounting box body 2, and the running object can be continuously monitored by the acoustic-optic alarm 72, and an acoustic-optic alarm signal can be issued according to the abnormality of the running object.

[0055] In one embodiment, as Figure 1 shown, the fixing mechanism 3 includes a first connecting plate 31 for connecting with the mounting box body 2, and a second connecting plate 32 for connecting with a fixed supporting surface (such as a wall and the like). Among them, the second through hole 311 is provided on the first mounting plate 31 for docking with the first through hole 21. At least one third through hole 321 is formed on the second connecting plate 32.

[0056] In this embodiment, as Figure 1 shown, two third through holes 321 are formed. Any fastener 8 convenient for fixing the second connecting plate 32 on the fixed supporting surface (such as a wall and the like) is arranged in the third through hole 321. In this embodiment, the fastener 8 is arranged as an expansion bolt. In this setting manner, the two fixing mechanisms 3 can be respectively arranged on the fixed supporting surface (such as a wall and the like) through the fastener 8.

[0057] According to a preferred embodiment of the present invention, as Figure 2 shown, the first connecting plate 31 and the second connecting plate 32 are perpendicularly arranged to each other. Specifically, the fixing mechanism 3 is integrally arranged in a structure with an "L" - shaped cross - section. In the illustrated embodiment, a reinforcing rib 33 is arranged between the first connecting plate 31 and the second connecting plate 32. In this way, the connection between the first connecting plate 31 and the second connecting plate 32 is made more stable.

[0058] According to a preferred embodiment of the present invention, as Figure 3 shown, the elastic member 6 is arranged as a helical spring.

[0059] The operation of the alarm control device 100 according to the present invention is as follows.

[0060] First, place the two fixing mechanisms 3 on the fixed supporting surface (such as a wall and the like), and adjust the relative distance between the two fixing mechanisms 3 so that the relative distance between the two fixing mechanisms 3 is adapted to the mounting box body 2. Meanwhile, pass the fastener 8 through the third through hole 312 located on the fixing mechanism 3 so that the fixing mechanism 3 forms a relative fixation with the fixed supporting surface (such as a wall and the like).

[0061] Secondly, the installation box body 2 is arranged between the two fixing mechanisms 3, and the first through holes 21 on both sides of the installation box body 2 are docked with the second through holes 311 on the fixing mechanisms 3.

[0062] Then, rotate the handle 533 so that the handle 533 drives the threaded rod 531 to rotate synchronously. During the continuous rotation of the threaded rod 531, the movable rod 522 arranged on the threaded rod 531 will continuously move vertically upward along the path formed by the guide rod 532. As the movable rod 522 continuously moves vertically upward, the connecting rod 521 connected to the movable rod 522 and the pushing part 51 arranged on the connecting rod 521 will move vertically upward synchronously.

[0063] During this process, the pushing part 51 will continuously push the thrust bearing platform 42 to compress the elastic member 6, and cause the thrust bearing platform 42 to drive the sliding column 41 to move along the position close to the first through hole 21 until the sliding column 41 moves into the first through hole 21 and the second through hole 311, and the pushing part 51 limits the thrust bearing platform 42. Thus, the installation box body 2 and the fixing mechanism 3 are connected.

[0064] When the lower end of the second inclined surface on the pushing part 51 contacts the upper end of the first inclined surface on the thrust bearing platform 42, the movable rod 522 will abut against the limiting boss 22 above the movable rod 522. At this time, the movable rod 522 cannot continue to move upward. Thus, it is avoided that the pushing part 51 is separated from the thrust bearing platform 42 during the upward movement.

[0065] Finally, a controller 1 is arranged on the installation box body 2, and the controller 1 continuously conducts safety monitoring on the user. However, the controller 1 can also be connected to the installation box body 2 first, and then the installation box body 2 is arranged on the fixing mechanism 3. Thus, the installation work of the alarm control device 100 is completed.

[0066] When it is necessary to disassemble the installation box body 2 from the fixing mechanism 3, the handle 533 is rotated in the direction opposite to the above-mentioned rotation direction. During this process, the movable rod 522 will continuously move downward along the path formed by the guide rod 532, so that the pushing part 51 gradually cancels the limit on the thrust bearing platform 42.

[0067] At this time, the elastic member 6 outside the sliding column 41 will continuously recover its elastic deformation, and push the thrust bearing platform 42 to drive the sliding column 41 to move along the position away from the first through hole 21 until the sliding column 41 is separated from the second through hole 311. Thus, the installation box body 2 and the fixing mechanism 3 are separated from each other, and the disassembly work of the alarm control 100 device is completed.

[0068] It will be understood that the present invention is described by way of some embodiments, and those skilled in the art will be aware that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
