Description

Technical Field

[0001] This utility model relates to the field of clock technology, and in particular to a clock that facilitates the replacement of components. Background Technology

[0002] The portable time synchronization clock is a portable, domestically produced, high-precision, reliable, and secure standard time source. It is characterized by its small size, light weight, and built-in lithium battery power supply, primarily serving the functions of secure timekeeping and time operation. The clock is placed inside a secure time synchronization device, which synchronizes and calibrates its built-in high-precision atomic clock, which then maintains the correct time. By transporting this clock, one-way isolated, reliable, and secure time synchronization can be provided to the secure time synchronization server deployed in the user's SMW system.

[0003] To meet high-precision timekeeping and protection requirements, existing portable timekeeping clocks typically have a compact internal structure, with core components such as the main control board often fixed to a bracket deep within the casing by multiple bolts. In actual maintenance, when the main control board malfunctions and needs replacement, the following problems arise: maintenance personnel usually need to remove numerous fixing bolts from the casing to access the internal areas, or even if an access port is provided, the confined internal space makes it difficult to insert tools, resulting in extreme difficulty in removing the bolts of the internal fixing components. The entire replacement process heavily relies on tools such as screwdrivers and wrenches. In field or emergency repair scenarios, if all tools are unavailable, maintenance cannot be performed. This traditional hard-connection fixing method significantly extends the mean time to repair (MTTR) of the equipment. For timekeeping systems requiring high reliability, excessive downtime can cause incalculable losses. Therefore, there is an urgent need for a structure that allows for rapid replacement of core components without complex tools. Utility Model Content

[0005] Therefore, one objective of this invention is to provide a clock that facilitates component replacement, thereby solving the problems mentioned in the background art and overcoming the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a clock with easily replaceable components, including a housing. A front panel and a rear panel are respectively embedded in the front and rear sides of the housing. A first circuit board and a second circuit board are respectively fixedly installed on the inner sides of the front and rear panels by bolts.

Two symmetrically arranged guide strips are slidably connected to the inner wall of the assembly frame. A main control board is fixedly connected between the two guide strips. A digital display screen is fixedly installed on the inner wall of the housing by bolts. The first circuit board, the second circuit board, and the digital display screen are all electrically connected to the main control board through a flexible circuit board. Two symmetrically arranged L-shaped locking frames are fixedly connected to one side of the assembly frame. Each L-shaped locking frame has a through hole in its horizontal part. A locking bolt is rotatably inserted into the through hole. The screw parts of the two locking bolts are threaded to the housing. An extension plate is fixedly connected to one end of the main control board. A spring is fixedly connected to the top of the extension plate. A snap-fit ​​pin is fixedly connected to the top of the spring. The bottom end of the snap-fit ​​pin passes through the extension plate and snaps into the assembly frame.

[0007] Preferably, the front sides of the first circuit board and the second circuit board are respectively fixedly connected with a coaxial socket and an interconnection interface, and the number of coaxial sockets is two. The coaxial sockets and the interconnection interface are respectively embedded inside the front panel and the rear panel.

[0008] Preferably, one side of the main control board is fixedly connected to several evenly distributed plug-in sockets, and the plug-in parts of the first circuit board, the second circuit board, and the flexible circuit board installed on the digital display screen are respectively plugged into the several plug-in sockets.

[0009] Preferably, one side of the assembly frame has a snap-fit ​​hole, and the bottom end of the snap-fit ​​pin passes through the extension plate and snaps into the assembly frame through the snap-fit ​​hole.

[0010] Preferably, one side of the assembly frame has a through-hole for rotation, and the assembly frame is rotatably connected to the connecting rod through the through-hole.

[0011] Preferably, in any of the above solutions, the inner wall of the assembly frame has two symmetrically arranged guide grooves, and the two guide strips are slidably connected to the assembly frame through the two guide grooves respectively.

[0012] Preferably, in any of the above schemes, the inner wall of the assembly frame is fixedly connected with a plurality of linear array positioning plates, and the plurality of positioning plates are all inserted into one end of the main control board.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. This device solves the problems of traditional clock timing relying on multiple bolts for fixing and cumbersome component replacement by using an assembly frame and snap-fit ​​structure. During operation, first open the inspection plate at the bottom of the housing, and pull out the first circuit board, second circuit board, and the flexible circuit board connector connecting the digital display to the main control board from the connector on one side of the main control board; then twist the locking bolt on the L-shaped locking frame to disengage it from the housing, releasing the lock on the assembly frame; pull the assembly frame to rotate it around the connecting rod through the rotating hole until the extension plate tilts upwards; next, pull the snap-fit ​​pin upwards to overcome the spring force, causing the bottom end of the snap-fit ​​pin to disengage from the snap-fit ​​hole of the assembly frame, releasing the lock on the main control board; finally, slide the guide strips on both sides of the main control board along the guide groove on the inner wall of the assembly frame to pull the main control board out of the assembly frame. When replacing a new main control board, reverse the above steps; there is no need to disassemble the entire housing or multiple fixing bolts. The entire process is simple to operate, requires no complicated tools, significantly shortens the main control board replacement time, reduces maintenance difficulty, reduces clock downtime, and avoids impacting peripheral systems that rely on it.

[0015] 2. This device employs a multi-positioning and guiding structure to ensure stable connection of the main control board and circuitry, preventing installation deviations from affecting equipment operation.

The positioning plate, guide strip, and guide groove work together to ensure that the main control board is installed in the same position every time, avoiding poor circuit contact due to installation deviation; the plug-in connection between the connector and the flexible circuit board is more stable than traditional wire welding and is easier to disassemble; the double fixing of the locking pin and locking bolt can prevent the main control board from loosening from the assembly frame, ensure the stability of the internal structure of the clock, and improve the safety and reliability of equipment operation.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0025] like Figures 1 to 7 As shown, a clock with easily replaceable components includes a housing 1. A front panel 2 and a rear panel 3 are embedded in the front and rear sides of the housing 1, respectively. A first circuit board 4 and a second circuit board 5 are fixedly mounted on the inner sides of the front panel 2 and the rear panel 3, respectively, by bolts. A connecting rod 6 is fixedly mounted on the inner wall of the housing 1. An assembly frame 7 is rotatably connected to the outer surface of the connecting rod 6. Two symmetrically arranged guide bars 8 are slidably connected to the inner wall of the assembly frame 7. A main control board 9 is fixedly connected between the two guide bars 8. A digital display screen 10 is fixedly mounted on the inner wall of the housing 1 by bolts. The first circuit board 4 and the second circuit board 5 are mounted on the rear panel 3. Both the circuit board 5 and the digital display screen 10 are electrically connected to the main control board 9 via a flexible circuit board. Two symmetrically arranged L-shaped locking brackets 11 are fixedly connected to one side of the assembly frame 7. Each L-shaped locking bracket 11 has a through hole in its horizontal portion, through which a locking bolt 12 is rotatably inserted. The threaded portions of both locking bolts 12 are threadedly connected to the outer casing 1. An extension plate 13 is fixedly connected to one end of the main control board 9. A spring 14 is fixedly connected to the top of the extension plate 13, and a locking pin 15 is fixedly connected to the top of the spring 14. The bottom end of the locking pin 15 passes through the extension plate 13 and engages with the assembly frame 7. An inspection port is provided at the bottom (or side) of the outer casing 1, where an inspection plate can be disassembled and installed.

[0026] As an optional technical solution of this utility model, the front sides of the first circuit board 4 and the second circuit board 5 are respectively fixedly connected with a coaxial socket 16 and an interconnection interface 17. There are two coaxial sockets 16. The coaxial sockets 16 and the interconnection interface 17 are respectively embedded inside the front panel 2 and the rear panel 3. This allows the coaxial sockets 16 and the interconnection interface 17 to form a regular external interface layout with the outer shell 1, which is convenient for staff to quickly identify and connect external devices. The front panel 2 and the rear panel 3 can also protect the sockets and interfaces to prevent external collisions or dust from entering and causing damage to the interfaces. At the same time, it ensures the connection stability between the interface and the circuit board and reduces signal transmission problems caused by loose interfaces.

[0027] As an optional technical solution of this utility model, a number of evenly distributed plug-in sockets 18 are fixedly connected to one side of the main control board 9. The plug-in parts of the flexible circuit boards installed on the first circuit board 4, the second circuit board 5, and the digital display screen 10 are respectively plugged into the several plug-in sockets 18. The flexible circuit board plug-in parts are directly plugged in and fixed, without the need for traditional wire soldering. This not only simplifies the circuit connection process and facilitates quick circuit separation when disassembling and replacing components, but also ensures the consistency and stability of the circuit connection, avoids poor contact caused by oxidation or detachment of solder joints. At the same time, the evenly distributed plug-in sockets 18 can reasonably plan the circuit layout of the main control board 9 and reduce the potential faults caused by messy wiring.

[0028] As an optional technical solution of this utility model, a snap-fit ​​hole 19 is provided on one side of the assembly frame 7. The bottom end of the snap-fit ​​pin 15 passes through the extension plate 13 and snaps into the assembly frame 7 through the snap-fit ​​hole 19. The snap-fit ​​pin 15 can be inserted through the extension plate 13 into the snap-fit ​​hole 19 to quickly lock the relative position of the main control board 9 and the assembly frame 7, preventing the main control board 9 from sliding or shifting within the assembly frame 7. Moreover, the snap-fit ​​structure is easy to operate. The locking can be released simply by pulling the snap-fit ​​pin 15 without removing the bolts. This not only ensures the stability of the main control board 9 after installation, but also further simplifies the disassembly and replacement steps of the main control board 9 and improves maintenance efficiency.

[0029] As an optional technical solution of this utility model, a rotating hole 20 is provided through one side of the assembly frame 7. The assembly frame 7 is rotatably connected to the connecting rod 6 through the rotating hole 20, providing a stable rotation fulcrum for the assembly frame 7. This allows the assembly frame 7 to rotate flexibly around the connecting rod 6, making it convenient for staff to rotate the assembly frame 7 to an angle that is easy to operate when replacing the main control board 9, thus avoiding inconvenience caused by the internal space of the outer shell 1.

[0030] As an optional technical solution of this utility model, the inner wall of the assembly frame 7 is provided with two symmetrically arranged guide grooves 21. The two guide bars 8 are slidably connected to the assembly frame 7 through the two guide grooves 21 respectively, providing precise guidance for the installation and removal of the main control board 9, ensuring that the main control board 9 moves along a fixed path, and avoiding damage to the inner wall of the assembly frame 7 due to positional deviation during installation. At the same time, the guide structure can make the main control board 9 and the assembly frame 7 fit more tightly, reduce the shaking of the main control board 9 during equipment operation, and ensure the stability of its circuit connection with other components.

[0031] As an optional technical solution of this utility model, the inner wall of the assembly frame 7 is fixedly connected with a plurality of linear array positioning plates 22. The plurality of positioning plates 22 are all inserted into one end of the main control board 9. The positioning plates 22 are provided with positioning grooves. When the main control board 9 slides along the guide groove 21 to the installation position, its end is embedded in the positioning groove. This can quickly achieve preliminary positioning when the main control board 9 is installed, ensuring that the installation position of the main control board 9 is accurate and avoiding misalignment between the plug-in seat 18 on the main control board 9 and the plug-in part of the flexible circuit board due to installation deviation. At the same time, the positioning plates 22 can provide support for one end of the main control board 9, distribute the force on the main control board 9, prevent the main control board 9 from bending and deforming due to excessive force on one end after long-term use, and extend the service life of the main control board 9.

[0032] A clock that facilitates component replacement works as follows:

[0033] 1): First, open the inspection board at the bottom of the outer casing 1, and pull out the soft circuit board connector of the first circuit board 4, the second circuit board 5 and the digital display screen 10 from the connector 18 on one side of the main control board 9.

[0034] 2): Twist the locking bolt 12 on the L-shaped locking bracket 11 to disengage it from the outer casing 1 and release the locking of the assembly bracket 7; pull the assembly bracket 7 to make it rotate around the connecting rod 6 through the rotating hole 20 until the extension plate 13 tilts upward.

[0035] 3): Pull the locking pin 15 upward to overcome the elastic force of the spring 14, so that the bottom end of the locking pin 15 disengages from the locking hole 19 of the assembly frame 7, thereby releasing the lock on the main control board 9; finally, push the guide strips 8 on both sides of the main control board 9 to slide along the guide groove 21 on the inner wall of the assembly frame 7, so that the main control board 9 can be pulled out from the assembly frame 7.

[0036] In summary, this clock transmitter, which facilitates component replacement, allows for easy replacement of the main control board 9 by reversing the steps described above, without requiring disassembly of the entire housing 1 and multiple fixing bolts. The entire process is simple, requiring no complex tools, significantly shortening the main control board replacement time, reducing maintenance difficulty, minimizing clock transmitter downtime, and preventing impact on peripheral systems that rely on it. The cooperation between the positioning plate 22, guide strip 8, and guide groove 21 ensures that the main control board 9 is always installed in the same position, preventing poor circuit contact due to installation deviations. The plug-in connection between the connector 18 and the flexible circuit board is more stable than traditional wire soldering and is easier to disassemble. The double fixing of the locking pin 15 and locking bolt 12 prevents the main control board 9 from loosening from the assembly frame 7, ensuring the stability of the internal structure of the clock transmitter and improving the safety and reliability of equipment operation.
