DETAILED DESCRIPTION

[0023] ​The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0024] The embodiments of the present application disclose a fixed-point device for fire safety patrol of Internet of Things. Figures 1 to 4 The fixed-point device for fire safety patrol of Internet of Things comprises an NFC card 1 and a sleeve 2, and a mounting seat 3 is hinged at one end of the sleeve 2 in length, and a containing cavity 31 is formed in the mounting seat 3, the sleeve 2 is hinged in the containing cavity 31 of the mounting seat 3, a mounting cavity 32 is formed in the mounting seat 3 above the containing cavity 31, a slide rod 321 arranged along the width direction of the mounting seat 3 is arranged in the mounting cavity 32 in a lifting mode, a clamping block 322 is fixedly connected to the lower end of the slide rod 321, and a clamping groove 21 is formed in the sleeve 2 corresponding to the clamping block 322 and used for embedding the clamping block 322, when the clamping block 322 is embedded in the clamping groove 21, the sleeve 2 and the mounting seat 3 are locked, and an adjusting mechanism for driving the slide rod 321 to ascend and descend in the mounting cavity 32 is arranged in the mounting seat 3 in the mounting cavity 32.

[0025] When the NFC card 1 needs to be installed, the NFC card 1 is first placed in the sleeve 2, then the sleeve 2 is placed in the containing cavity 31 of the mounting seat 3, the slide rod 321 is driven to descend by operating the adjusting mechanism, the clamping block 322 fixedly connected to the slide rod 321 is driven to descend, and the clamping block 322 is embedded in the clamping groove 21 of the sleeve 2 until the sleeve 2 and the mounting seat 3 are locked; when the NFC card 1 needs to be removed, the slide rod 321 is driven to ascend by reversely operating the adjusting mechanism, the clamping block 322 fixedly connected to the slide rod 321 is driven to ascend, the clamping block 322 is separated from the clamping groove 21 of the sleeve 2, the locking between the sleeve 2 and the mounting seat 3 is released, and the NFC card 1 is taken out. Through the ingenious locking and unlocking mechanism, the NFC card 1 is conveniently installed and removed in the fire safety patrol, and the problem that the fixed-point device has the deficiency in the aspect of anti-disassembly, affects the safety and reliability, and increases the management difficulty is effectively solved.

[0026] Specifically, referring to Figure 1 and Figure 2 , the adjusting mechanism comprises a rack 41 and a gear 4 in mesh connection, the rack 41 is arranged in the mounting cavity 32 and fixedly connected to the upper end of the slide rod 321 along the length direction of the slide rod 321, one end of the gear 4 is rotatably connected to the seat, the other end of the gear 4 is provided with a special-shaped groove 42, the mounting seat 3 is provided with a lock hole (not shown in the figure) corresponding to the special-shaped groove 42 and the inner diameter of the special-shaped groove 42 is smaller than the inner diameter of the lock hole, and the adjusting mechanism further comprises a locking assembly for driving the gear 4 to rotate.

[0027] and referring to Figure 1 andFigure 2 The locking assembly includes a shaped block 5 adapted to the shaped groove 42, a straight rod 51 and a handle 52, one end of the straight rod 51 being fixedly connected to the shaped block and the other end being fixedly connected to the handle 52.

[0028] When it is necessary to lock the housing 2 and the mounting base 3, the irregular block 5 is inserted into the lock hole and embedded in the irregular groove 42. The handle 52 is turned, the gear 4 rotates and drives the rack 41 to descend, causing the slide bar 321 to descend, thereby causing the locking block 322 to descend and embed into the locking groove 21.

[0029] When it is necessary to unlock the housing 2 from the mounting base 3, the irregularly shaped block 5 is inserted into the lock hole and embedded in the irregularly shaped groove 42. The handle 52 is rotated in the opposite direction, and the gear 4 rotates, causing the rack 41 to rise, which in turn causes the slide bar 321 to rise, thereby causing the locking block 322 to rise and disengage from the slot 21. Through the precise cooperation between the irregularly shaped block 5 and the irregularly shaped groove 42, and the rotation of the handle 52, precise control of the raising and lowering of the slide bar 321 can be achieved, thereby ensuring that the locking block 322 can be accurately embedded in the slot 21 to achieve a stable lock. Moreover, the user only needs to insert the irregularly shaped block 5 into the lock hole and embed it in the irregularly shaped groove 42, and then rotate the handle 52 to complete the locking operation, without the need for complicated tools or steps. Furthermore, the unique design of the irregularly shaped block 5 and the irregularly shaped groove 42 can prevent unauthorized personnel from easily unlocking the device, thereby improving the security of the device.

[0030] Furthermore, referring to Figure 3 and Figure 4 A telescopic rod 6 is provided between the bottom wall of the accommodating cavity 31 and the housing 2. One end of the telescopic rod 6 is fixedly connected to the mounting base 3 and the other end is hinged to the housing 2. A spring 7 is provided on the outer sleeve of the telescopic rod 6. When the housing 2 is locked to the mounting base 3, the spring 7 is in a compressed state.

[0031] This design ensures that the housing 2 remains stable during opening and closing, preventing it from shaking or tilting. Furthermore, the compression and release of the spring 7 assists in opening and closing the housing 2. When the user needs to open the housing 2, the spring force of the spring 7 helps open it more easily. Similarly, when closing the housing 2, the compression of the spring 7 provides clear feedback to the user, indicating that the housing 2 is close to the locked position. This design makes operating the housing 2 easier and less strenuous, improving operational convenience. Simultaneously, the combination of the telescopic rod 6 and the spring 7 enhances the overall stability and reliability of the device, making the housing 2 more secure and easier to operate on the mounting base 3.

[0032] Furthermore, referring to Figure 3 and Figure 4The telescopic rod 6 is provided with an upper limiting sheet 61 and a lower limiting sheet 62. The upper limiting sheet 61 is arranged to limit the maximum stroke of the telescopic rod 6. When the telescopic rod 6 abuts against the lower limiting sheet 62, the telescopic rod 6 stops compression and the clamping block 322 is aligned with the clamping groove 21.

[0033] The upper limiting sheet 61 is arranged inside the telescopic rod 6 to limit the maximum extension length of the telescopic rod 6. When the telescopic rod 6 extends to the upper limiting sheet 61, it is hindered from further extension, thereby avoiding damage or instability caused by excessive extension. The lower limiting sheet 62 is designed to contact the telescopic rod 6 when it is compressed to the limit position. When the telescopic rod 6 abuts against the lower limiting sheet 62, it stops further compression. At this time, the length of the telescopic rod 6 is just right for the clamping block 322 to be aligned with the clamping groove 21, which enables the clamping block 322 to be accurately embedded in the clamping groove 21 when the shell 2 is locked with the mounting seat 3, achieving stable locking. Through the effective combination of the upper limiting sheet 61 and the lower limiting sheet 62, the clamping block 322 and the clamping groove 21 are accurately aligned during the locking process, improving the accuracy and reliability of the locking. At the same time, the operator does not need to pay excessive attention to the position or force of the telescopic rod 6, and can easily complete the locking and unlocking operations, reducing the operation difficulty.

[0034] And, referring to Figure 3 and Figure 4 The spring 7 is a conical compression spring 7, and the larger outer diameter end thereof is located at the bottom of the accommodating cavity 31. When the conical compression spring 7 is compressed, due to its shape characteristics, it can provide more stable and uniform elastic force. This stable elastic force helps to maintain the smooth movement of the telescopic rod 6 and prevent shaking or jamming caused by uneven elastic force.

[0035] At the same time, referring to Figures 1 to 4 One end of the clamping block 322 corresponding to the clamping groove 21 is provided with a chamfer (not shown in the figure), and the part of the clamping groove 21 corresponding to the chamfer is provided with an arc-shaped part (not shown in the figure). The design of the chamfer and the arc-shaped part enables the clamping block 322 to be more easily and accurately embedded in the clamping groove 21, thereby improving the efficiency of the locking. It also reduces the direct contact and friction between the clamping block 322 and the clamping groove 21, thereby reducing wear and noise, which helps to prolong the service life of the device.

[0036] In addition, referring to Figures 1 to 4The transparent sleeve 2 is made of transparent material, and the transparent sleeve 2 can clearly display the content of the NFC card 1, such as a two-dimensional code, a bar code, text information and the like, and the content can be directly viewed without opening the sleeve 2, the intuitiveness improves the information transmission efficiency of the device, and the operator is more convenient and fast when checking or scanning the NFC card 1; and corresponding letter or number marks (not shown in the figure) are arranged on the sleeve 2 and the NFC card 1, the marks can be used to distinguish different NFC cards 1 or devices, and the operator can more accurately identify the required NFC card 1 by comparing the marks on the sleeve 2 and the NFC card 1, so that the error operation caused by confusion is avoided.

[0037] The implementation principle of the fixed-point device for the fire safety patrol of the Internet of Things according to the embodiment of the application is as follows:

[0038] When the NFC card 1 needs to be installed, the NFC card 1 is first placed in the sleeve 2, then the sleeve 2 is placed in the accommodating cavity 31 of the mounting seat 3, the adjusting mechanism is operated to lower the slide rod 321, the slide rod 321 drives the clamping block 322 fixedly connected thereto to lower until the clamping block 322 is embedded in the clamping groove 21 of the sleeve 2, so that the sleeve 2 and the mounting seat 3 are locked; when the NFC card 1 needs to be removed, the adjusting mechanism is operated in reverse to raise the slide rod 321, the slide rod 321 drives the clamping block 322 fixedly connected thereto to rise, so that the clamping block 322 is separated from the clamping groove 21 of the sleeve 2, the locking between the sleeve 2 and the mounting seat 3 is released, and the NFC card 1 is taken out. Through the ingenious locking and unlocking mechanism, the NFC card 1 is conveniently installed and removed in the fire safety patrol, and the problem that the fixed-point device has deficiencies in anti-disassembly, affects the safety and reliability, and increases the management difficulty is effectively improved.
