DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides a PCB board locking device, which can solve the problem that the device cannot be flexibly and accurately reset after the PCB board is installed, is not convenient for subsequent reuse, and has low efficiency.

[0025] Since the PCB board cannot be flexibly and accurately reset after installation, an automatic reset auxiliary part is added on the basis of the abutment part abutting the PCB board, and the structure of the abutment part is adjusted so that the abutment part can be used in conjunction with the automatic reset auxiliary part. The reset principle of the device is as follows: the spring is used as an automatic reset auxiliary part, and a part is added to the abutment part. When the abutment part abuts the PCB board, the part can also press the spring. When the locking state is reached, the abutment part abuts the PCB board and the spring at the same time. When the PCB board is installed and the locking device is released, the spring recovers its deformation to generate elastic potential energy to push the abutment part, so that the entire device can be quickly reset.

[0026] refer to Figure 1-4 A PCB board locking device comprises: a positioning base 2, a bottom of which has a chamber for clamping on a connector 1; a PCB abutment 3, part of which is arranged in the chamber by an elastic member; a pushing component 4, which is located in the chamber and pushes the PCB abutment 3 to abut against a PCB board 5; a locking component, which is installed on the positioning base 2 and locks or releases the pushing component 4.

[0027] Through this design, the bottom of the positioning base 2 is provided with a chamber, which can stably clamp the connector 1 and ensure that the PCB board 5 is accurately positioned during the installation process; the PCB abutment 3 can stably abut the PCB board 5 while pressing the elastic member located in the chamber. When the PCB board 5 is installed, the elastic member restores its deformation to generate elastic potential energy to push the PCB abutment 3 to reset it; the pushing component 4 is located in the chamber, and fixes the PCB board 5 by pushing the PCB abutment 3 to ensure that the PCB board 5 will not shake or shift during the assembly process. The locking component is installed on the positioning base 2, which is responsible for locking or releasing the pushing component 4, and then cooperating with each other to lock or reset the PCB abutment 3, which is convenient for repeated use and improves operating efficiency.

[0028] In some preferred embodiments, the top of the positioning base 2 includes a protruding cover plate 6 having an opening, and the bottom of the positioning base 2 includes a receiving groove connected to the opening, and the opening and the receiving groove form a chamber. By adding the protruding cover plate 6 and the receiving groove, the design of the PCB board 5 locking device is more convenient to operate and observe, making the installation of the PCB board 5 more convenient and accurate.

[0029] In some preferred embodiments, an inclined portion 21 is provided on the inner wall of the chamber, and a second screw hole 211 is provided on the inclined portion 21; the locking component is a clevis bolt 7; the clevis bolt 7 penetrates the push component 4 along its length direction and is locked in the second screw hole 211; the clevis bolt 7 resists and pushes the push component 4; the push component 4 slides along the inclined portion 21 and resists the PCB resisting member 3. These are some important design points in the preferred embodiment of the PCB board 5 locking device, the inclined portion 21 and the second screw hole 211: an inclined portion 21 is provided on the inner wall of the locking base 2, and a second screw hole 211 is provided on the inclined portion. This setting can provide an inclined surface for matching with the locking component (clevis bolt 7), and the inclined portion 21 enables the clevis bolt 7 to more easily push the push component 4 and lock on the second screw hole 211. The clevis bolt 7, as a locking component, penetrates the push component 4 along its length direction and is locked on the second screw hole 211. The clevis bolt 7 realizes the locking action by pushing on the inclined portion 21 to ensure the fixity of the PCB board. The push assembly 4 is pushed and locked by the clevis bolt 7, and slides along the inclined portion 21. Its main function is to fix the PCB board by contacting with the PCB board abutment 3; through such a design, the PCB board 5 locking device can achieve accurate locking operation.

[0030] In some preferred embodiments, the push assembly 4 includes an upper inclined block 41 and a lower inclined block 42; the upper inclined block 41 is provided with a first screw hole 411; the diameter of the first screw hole 411 and the diameter of the second screw hole 211 are both consistent with the diameter of the horn bolt 7; the lower inclined block 42 is provided with a through hole 421; and the diameter of the through hole 421 is larger than the diameter of the horn bolt 7; the horn bolt 7 passes through the first screw hole 411 and the through hole 421, and is locked or separated in the second screw hole 211. The push assembly 4 includes an upper inclined block 41 and a lower inclined block 42, and these two components play an important role in the PCB board locking device. The upper inclined block 41 is a part of the push assembly 4, and is provided with a first screw hole 411. The caliber of the first screw hole 411 matches the caliber of the clevis bolt 7. This design ensures that the clevis bolt 7 can smoothly pass through the first screw hole 411, and cooperate with it, that is, the clevis bolt 7 squeezes and pushes the upper inclined block 41. The lower inclined block 42 is also a part of the pushing component 4, and a through hole 421 is provided on it. Compared with the first screw hole 411, the caliber of the through hole 421 is larger than the caliber of the clevis bolt 7. The clevis bolt 7 expands and contracts along its length direction, and can pass through the first screw hole 411 and the through hole 421, locking or releasing the pushing component 4 into the second screw hole 211. Through the design of the upper inclined block 41, the lower inclined block 42 and the corresponding screw holes, a reliable locking mechanism is formed between the pushing component 4 and the locking component (clevis bolt 7), ensuring the stable fixation of the PCB board 5.

[0031] In some preferred embodiments, the bottom of the upper inclined block 41 is provided with a first inclined surface 43; the top of the lower inclined block 42 is provided with a second inclined surface 44 that fits and slides with the first inclined surface 43; the bottom of the lower inclined block 42 is provided with a third inclined surface 45 that fits and slides with the inclined portion 21; the lower inclined block 42 slides along the inclined portion 21 and abuts against the PCB abutment 3. The upper inclined block 41 and the lower inclined block 42 of the push assembly 4 have more design details: the bottom of the upper inclined block 41 is designed with a first inclined surface 43, which is an inclined surface. The function of the first inclined surface 43 is to guide the lower inclined block 42 to slide and play an auxiliary role in the locking or releasing process. The top of the lower inclined block 42 is designed with a second inclined surface 44, which fits and slides with the first inclined surface 43 of the upper inclined block 41. In addition, the bottom of the lower inclined block 42 is designed with a third inclined surface 45, which fits and slides with the inclined portion 21. The design of these inclined surfaces enables the lower inclined block 42 to move smoothly in the lateral direction, thereby realizing the locking or releasing operation. During the sliding process, the lower inclined block 42 slides along the inclined portion 21 and abuts against the PCB abutment 3. This ensures that the PCB abutment 3 is in the correct position between the components and plays a supporting and fixing role during assembly. Through the above design, a more complex connection relationship is formed between the upper inclined block 41 and the lower inclined block 42 of the push component 4, which can more accurately control the movement of the push component 4 and ensure the stable fixation of the PCB board 5.

[0032] In some preferred embodiments, the PCB abutting member 3 includes an abutting portion 31 and a pressing portion which are arranged perpendicular to each other; the abutting portion 31 is arranged to pass through the chamber; the elastic member is a spring 8; one end of the spring 8 is arranged at the pressing portion, and the other end is connected to the inner wall of the chamber; one side of the abutting portion 31 abuts against the PCB board 5, and the other side abuts against the vertical surface of the lower inclined block 42. In this design, through the design of the abutting portion 31 and the pressing portion, the PCB board 5 can be effectively fixed to ensure that the PCB board 5 maintains a stable position during the installation process; the spring 8 as an elastic member can provide a certain elastic support and buffering effect, and when the locking device is released, the elastic force of the spring 5 can help the abutting member to quickly reset; connecting one end of the spring 8 to the inner wall of the chamber can effectively fix the position of the spring, ensure that the spring can correctly release the elastic force during the reset process, and provide necessary support. This design structure can provide stable support and quick reset function, helping the device to be more convenient, safe and efficient during use.

[0033] In some preferred embodiments, the protruding cover plate 6 includes an upper cover plate 61 and a lower cover plate 62, and a cover opening is provided on the lower cover plate 62; the lower cover plate 62 is connected to the positioning base frame 2 by nuts 9; and the upper cover plate 61 is provided on the cover opening of the lower cover plate 62 by nuts 9. This part mainly emphasizes the design structure of the positioning base frame 2. Through this design structure, the lower cover plate 62 is connected to the positioning base frame 2 by nuts 9, and the upper cover plate 61 is fixed to the cover opening of the lower cover plate 62, which can ensure that the structure is stable and reliable, and has stronger anti-seismic and anti-compression capabilities; secondly, the upper cover plate 61 and the lower cover plate 62 can be designed and manufactured separately, and are independent of each other but can be combined together, which is conducive to production and maintenance.

[0034] In some preferred embodiments, a clamping block for docking the connector 1 is provided at the bottom of the positioning base 2. Through the design of the clamping block, the positioning base 2 can better align with the connector 1, thereby making the locking operation more streamlined and avoiding loosening or falling off during use.

[0035] In some preferred embodiments, the positioning base frame 2 is further provided with an operation port 22 for subsequent operations. It should be noted that the design of the operation port 22 is mainly to provide an operation space for the docking operation between the PCB board 5 and the patch panel 1 after the PCB board 5 is locked. The operation port 22 ensures that after the PCB board 5 is locked, other components will not hinder the docking process between the patch panel 1 and the positioning base frame 2, making the installation operation more convenient and efficient. It can bring significant convenience in both production and maintenance processes.

[0036] In some preferred embodiments, the locking assembly is a high-pressure cylinder assembly 10; the high-pressure cylinder assembly 10 includes a telescopic cylinder 101; the telescopic cylinder 101 is arranged at the opening of the protruding cover plate 6, and its output end is pressed on the top of the pushing assembly 4; a high-pressure gas pipe 102 is provided on the top of the telescopic cylinder 101. This is another design scheme, the telescopic cylinder 101 is located at the opening of the protruding cover plate 6, and its output end is pressed on the top of the pushing assembly 4. The telescopic cylinder 101 is used to achieve telescopic action through the change of gas pressure, thereby pushing the pushing assembly 4 connected thereto. A high-pressure gas pipe 102 is provided on the top of the telescopic cylinder 101, which is used to connect a pipeline for supplying high-pressure gas. High-pressure gas enters the telescopic cylinder 101 through the pipeline, generating the required gas pressure to complete the telescopic action. Through this design, the high-pressure cylinder assembly 10 realizes the locking function, and uses the telescopic cylinder 101 as a pushing element, and provides a gas source through the high-pressure gas pipe 102, so as to achieve the purpose of applying pressure on the top of the pushing assembly 4 to achieve locking.

The device can flexibly lock and reset the PCB abutment, is convenient for repeated use, and improves operating efficiency.
