Description

Technical Field

[0001] This utility model belongs to the technical field of fire protection maintenance devices, and specifically relates to a fire protection maintenance device. Background Technology

[0002] Because fire protection facilities in buildings and other structures are often left unused for extended periods, they may malfunction or become damaged under the continuous influence of the external environment. Therefore, maintenance personnel need to regularly inspect and maintain the fire protection facilities with their tools. However, there are many types of maintenance tools, so they need to be stored in a unified manner for easy carrying and storage.

[0003] In related existing technologies, such as Chinese Patent No. CN223084774U, a portable fire protection maintenance and testing box is disclosed. This box includes an inner liner, a frame fixed to the middle of the outer wall of the inner liner, and sliding brackets fixed to the middle of both ends of the frame. Two boxes are respectively located on either side of the frame. A locking sleeve is symmetrically fixed to the middle of the outer wall of box one, and a latch is provided on the locking sleeve. A locking sleeve is symmetrically fixed to the middle of the outer wall of box two, and a hook block adapted to the latch is fixedly connected to the outer wall of locking sleeve two near one end of locking sleeve one. This solution, through the rational design of the frame, inner liner, box one, and box two, achieves the orderly placement and fixation of equipment and tools, saving space and improving efficiency. Box one and box two can slide open to the sides, exposing the tools inside for convenient and flexible access. This allows users to quickly locate equipment and tools, improving work efficiency, and the latches provide excellent fixation.

[0004] However, in actual use, it is difficult for users to clearly remember whether the tool is placed in box one or box two, which means that workers need to open and close box one and box two at the same time. In the above solution, box one and box two need to be operated and controlled separately when opening and closing relative to the box frame, which makes the use more cumbersome and labor-intensive, and is not conducive to actual use. Utility Model Content

[0005] The present invention aims to provide a fire protection maintenance device to solve the problems mentioned above, such as the cumbersome and labor-intensive process of opening and closing existing fire protection maintenance toolboxes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire protection maintenance device, comprising...

[0007] The box frame is equipped with a telescopic plate assembly on top.

[0008] The box body has two symmetrically arranged boxes about the frame. The top of the box body is rotatably mounted with a first mounting plate, which is fixed to the movable end of the telescopic plate assembly.

[0009] Limiting mechanism is used to restrict the movement of the telescopic plate assembly;

[0010] The synchronization mechanism includes a gear, a rack, and a second mounting plate. The second mounting plate is rotatably mounted on the bottom of the housing. A rack is fixed to the side wall of the second mounting plate and is slidably disposed on the bottom of the housing frame. The gear is fixed to the bottom of the housing, and the rack meshes with the gear.

[0011] The principle and effects of this technical solution:

[0012] 1. By installing racks in both housings, with a gear meshing between the two racks, when one housing moves the second mounting plate away from or towards the housing frame, the rotation of the gear drives the rack on the other side to move the second mounting plate and housing away synchronously. This synchronous approach and departure setting allows the user to control the position of one housing frame to simultaneously open or close both housings when the device needs to be opened or closed, thereby reducing the steps required to open or close the other housing and saving manpower.

[0013] 2. By setting the limiting mechanism, the position of the telescopic plate assembly can be restricted, thereby limiting the position of the first mounting plate relative to the box frame, that is, limiting the position of the box body relative to the box frame, so as to keep the box body in a stable position relative to the box frame.

[0014] The present invention is further configured such that: the synchronization mechanism also includes a protective frame, the protective frame is fixed to the bottom of the box, the cross section of the protective frame is "U" shaped, the gear and the rack are both movable inside the protective frame, the inner wall of the protective frame is provided with a guide groove, the cross section of the guide groove is inverted "T" shaped, and a slider that slides in cooperation with the guide groove is fixed on the side of the rack away from the gear.

[0015] The principle and effect of this technical solution: The protective frame can provide a certain degree of protection for the meshing point of the gear and rack. Furthermore, the guide groove and slider guide and limit the sliding of the rack, allowing it to move only horizontally, thereby ensuring the stability of the synchronization mechanism.

[0016] The present invention is further configured such that: the telescopic plate assembly includes a fixed plate, a movable plate and a limiting rod, the fixed plate is fixed to the box body, the movable plate is slidably inserted into the fixed plate, and the end of the movable plate is fixed to the first mounting plate, a limiting groove is provided on the side wall of the fixed plate, the limiting rod is fixed to the side wall of the movable plate, and the limiting rod is movably installed in the limiting groove.

[0017] The principle and effect of this technical solution: By setting up a fixed plate, a movable plate and a limiting rod, the movable plate can control the position of the first mounting plate relative to the box frame by changing the length of its fit with the fixed plate, and the sliding of the limiting rod in the limiting groove restricts the movable plate from detaching from the fixed plate.

[0018] The present invention is further configured such that: the limiting mechanism includes an installation cylinder, a limiting plate, a pressure plate, a spring, and a pull ring; a slot is provided on the movable plate; the limiting plate and the fixed plate are slidably inserted into each other; and the end of the limiting plate can extend into the slot; the installation cylinder is fixed on the fixed plate and is movably fitted onto the limiting plate; the pressure plate is fixed on the limiting plate and is slidably fitted into the installation cylinder; the pull ring is fixed at the end of the limiting plate away from the movable plate; and the spring is installed in the installation cylinder and is located on the side of the pressure plate away from the fixed plate.

[0019] The principle and effect of this technical solution: By inserting the limiting plate into the slot, the sliding of the movable plate relative to the fixed plate can be restricted, that is, the position of the box body relative to the box frame is limited. Through the setting of the pressure plate and spring, the limiting plate can maintain a certain stability when inserted into the slot. That is, the vibration and shaking during transportation can be overcome to a certain extent by the rebound force of the spring, thereby preventing the limiting plate from falling out of the slot. The setting of the pull ring facilitates the control of the limiting plate.

[0020] The present invention is further configured such that a guide surface is provided at the lower end of the limiting plate near the box body.

[0021] The principle and effect of this technical solution: The setting of the guide surface allows the slot to automatically drive the limiting plate out of the slot by pressing against the guide surface when the movable plate slides into the fixed plate, thus eliminating the need for manual pulling of the pull ring and saving manpower.

[0022] The present invention is further configured such that: a guide cylinder is fixed to the side wall of the box frame, and a guide plate is slidably fitted to the side wall of the box body, and the guide plate can be inserted into the guide cylinder.

[0023] The principle and effect of this technical solution: By setting up the guide cylinder and guide plate, when the box and box frame are in the storage state, the guide plate can be inserted into the guide cylinder to guide and limit the rotation of the box relative to the first mounting plate and the second mounting plate, thereby improving the stability of the box when it is stored. In addition, the sliding fit of the guide plate relative to the box allows the guide plate to change the overlapping area with the box by sliding, thereby making way and avoiding the box when it rotates.

[0024] The present invention is further configured such that: the first mounting plate has a vertical side and a horizontal side, the vertical side is connected to the movable end of the telescopic plate assembly, and the horizontal side is rotatably connected to the box body.

[0025] The principle and effect of this technical solution: By setting the vertical and horizontal sides, the position where the first mounting plate is connected to the movable end of the telescopic plate assembly can be staggered from the position where the first mounting plate is rotatably connected to the box. That is, the vertical and horizontal sides can be used for transition, so that the rotation axis of the first mounting plate and the box can be kept on the same vertical line as the rotation axis of the second mounting plate and the box, thus avoiding rotational interference.

[0042] Example:

[0043] As attached Figure 1-8 As shown, a fire protection maintenance device includes a frame 110, a housing 210, a limiting mechanism, and a synchronization mechanism. A telescopic plate assembly is installed on the top of the frame 110. Two housings 210 are symmetrically arranged about the frame 110. A first mounting plate 220 is rotatably mounted on the top of the housing 210. The first mounting plate 220 has a vertical side 221 and a horizontal side 222. The vertical side 221 is connected to the movable end of the telescopic plate assembly, and the horizontal side 222 is rotatably connected to the housing 210 (the specific shape and positional relationship are shown in the attached figure. By extending the vertical side 221 and the horizontal side 222, the extension assembly can allow the housing 210 to rotate relative to the frame 110 after opening, while keeping the maximum and minimum strokes unchanged). The first mounting plate 220 is fixed to the movable end of the telescopic plate assembly. The telescopic plate assembly includes a fixed plate 410, a movable plate 420, and a limiting rod 430. The fixed plate 410 is fixed to the housing 210. Two movable plates 420 are slidably inserted into both sides of the fixed plate 410, and the ends of the movable plates 420 are fixed to the vertical edge 221 of the first mounting plate 220. A limiting groove 411 is provided on the side wall of the fixed plate 410. The limiting rod 430 is fixed to the side wall of the movable plate 420, and the limiting rod 430 is movably installed in the limiting groove 411. The sliding of the limiting rod 430 in the limiting groove 411 can limit the stroke of the movable plate 420.

[0044] The limiting mechanism is used to restrict the movement of the telescopic plate assembly. The limiting mechanism includes a mounting cylinder 510, a limiting plate 520, a pressure plate 530, a spring 540, and a pull ring 550. Two slots 421 are provided on the movable plate 420 (one for auxiliary limitation of the maximum stroke, and one for stable positioning during storage; the slot 421 for limiting the maximum stroke position is not shown in the figure. The two slots 421 are located at both ends of the movable plate 420). The limiting plate 520 is slidably inserted into the fixed plate 410 (two limiting mechanisms are provided with respect to the fixed plate 410, each corresponding to one). The movable plate 420 and the end of the limiting plate 520 can extend into the slot 421. The mounting cylinder 510 is fixed on the fixed plate 410 and is movably fitted onto the limiting plate 520. The pressure plate 530 is fixed on the limiting plate 520 and slides within the mounting cylinder 510. The pull ring 550 is fixed to the end of the limiting plate 520 away from the movable plate 420. The spring 540 is installed inside the mounting cylinder 510 and is located on the side of the pressure plate 530 away from the fixed plate 410. A guide surface 521 is provided at the lower end of the limiting plate 520 near the housing 210.

[0045] The synchronization mechanism includes a gear 310, a rack 320, a protective frame 340, and a second mounting plate 330. The second mounting plate 330 is rotatably mounted on the bottom of the housing 210. The rack 320 is fixed to the side wall of the second mounting plate 330 and is slidably disposed on the bottom of the housing frame 110. The gear 310 is fixed to the bottom of the housing 210, and the rack 320 meshes with the gear 310 (the racks 320 corresponding to the two housings 210 are located on both sides of the gear 310). The protective frame 340 is fixed to the bottom of the housing 210 and has a "U" shaped cross section. The gear 310 and the rack 320 are both movable inside the protective frame 340. The inner wall of the protective frame 340 has a guide groove 341 with an inverted "T" shaped cross section. A slider 342 that slides with the guide groove 341 is fixed on the side of the rack 320 away from the gear 310.

[0046] A guide cylinder 610 is fixed to the side wall of the box frame 110, and a guide plate 620 is slidably fitted to the side wall of the box body 210. The guide plate 620 can be inserted into the guide cylinder 610. The bottom of the box body 210 has a support foot on the side away from the box frame 110. Support feet are provided on the front and rear sides of the bottom of the box frame 110. The support feet are used to raise the box body 210 and the box frame 110 so that the synchronization mechanism has sufficient room for movement. Both the box body 210 and the box frame 110 are provided with a sponge pad for preventing maintenance tools. The sponge pad is provided with a corresponding receiving cavity for preventing maintenance tools, and the shape of the receiving cavity is set according to the shape of the maintenance tool.

[0047] When the device needs to be opened, first pull the pull rings 550 on both sides to disengage the limiting plate 520 from the slot 421. Simultaneously, control one side of the housing 210 to move away from the frame 110. Since the guide plate 620 has not yet left the guide cylinder 610, the housing 210 cannot rotate relative to the first mounting plate 220 and the second mounting plate 330. After the limiting plate 520 and slot 421 are no longer aligned, continue pulling one side of the housing 210 away from the frame 110. At this point, the housing 210 can rotate at a small angle, and following the principle of the housing 210… The larger the angle that the housing 210 can rotate, the more it can rotate 180° when it reaches the maximum stroke. At this time, the limit plate 520 is inserted into the maximum stroke limit slot 421 to limit the position of the movable plate 420. After taking out the corresponding maintenance tools, the housing 210 is rotated to a state parallel to the frame 110. Then, the housing 210 on one side is pushed to drive the movable plate 420 into the fixed plate 410, so that the housings 210 on both sides move synchronously and move closer to the frame 110 for storage.

[0048] The synchronous movement of the two housings 210 is achieved through transmission via the rack 320 and gear 310 in the synchronization mechanism.

[0049] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0050] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing.
