[0001] The utility model relates to the technical field of PIN pin anti - dropping, and specifically relates to a PIN pin anti - dropping device. Background Technique

[0002] As PIN pins in electronic devices or industrial devices, common shapes are series such as four - prong pins and round pins, and additional fixing measures or anti - dropping designs are required to ensure that the PIN pins will not accidentally loosen or fall off during transportation, installation, or use;

[0003] A Chinese patent with the publication number CN217182175U discloses a PIN pin socket, which includes a socket body. The socket body has a hollow main body part, a first flange and a second flange radially extending outward at both ends of the main body part; at least one locking hole is provided on the first flange and the second flange. The utility model can effectively prevent the welding between the socket and the copper - clad layer on the insulating substrate from loosening and avoid the problem of PIN pin falling off;

[0004] When the above - mentioned PIN pins are installed, the phenomenon of the pin body falling off will occur, which causes the pin body to be contaminated. Picking up and wiping the pin body takes more time, resulting in a longer time for the entire installation operation of the pin body and affecting the installation efficiency of the PIN pins; therefore, a PIN pin anti - dropping device is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve some existing problems of PIN pin anti - dropping, the utility model proposes a PIN pin anti - dropping device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A PIN pin anti - dropping device described in the utility model includes a base; a lifting seat is installed on the top of the base; a rotating shaft is rotatably installed on the top of one side structure surface of the lifting seat; an anti - dropping auxiliary device is installed on the lifting seat; the anti - dropping auxiliary device includes a limiting plate; the limiting plate is connected to the rotating shaft through a fixing ring; sliding grooves are symmetrically opened on both side structure surfaces of the limiting plate; sliding blocks are arranged inside the sliding grooves; a limiting frame is fixedly connected to the body of the sliding block; telescopic cavities are equidistantly opened on the bottom end surface of the limiting frame; springs are installed inside the telescopic cavities; a pressing block is arranged on the inner wall of the telescopic cavity; the bottom of the spring is connected to the top of the pressing block.

[0007] A pressing cavity is formed through the bottom of the pressing block; rolling beads are rotatably installed at positions near the openings at both ends of the top end face of the inner wall of the pressing cavity; placing grooves are equidistantly formed on the acting structure surface of the limiting plate; insertion holes are formed in the top of the base; when the limiting plate is in a vertical state, the center line of the placing groove coincides with the center line of the corresponding insertion hole; a needle body is placed inside the placing groove; to prevent the needle body from falling during installation.

[0008] Preferably, when the spring is not working, it does not deform, and at this time, the horizontal plane where the bottom end face of the pressing block is located coincides with the horizontal plane where the acting end face of the limiting plate is located; enabling the pressing block to operate smoothly.

[0009] Preferably, clamping grooves are formed at the ends of the sliding grooves; the width of the sliding block is smaller than the width of the sliding groove; enabling the sliding block to be smoothly clamped inside the clamping groove.

[0010] Preferably, structure cavities are formed on both sides inside the base; a small motor is installed inside the structure cavity; a screw rod is installed at the top of the output shaft of the small motor; threaded holes are symmetrically formed on the bottom end face of the lifting seat; the screw rod passes through the base and is inserted into the threaded hole; providing power for the lifting of the lifting seat.

[0011] Preferably, a fixing seat is fixedly connected to one side structure surface of the lifting seat; a limiting ring is fixedly connected to the side of the fixing seat close to the limiting plate; a moving rod is slidably installed inside the limiting ring; an insertion block is fixedly connected to the end of the moving rod close to the limiting plate; an insertion groove is formed at the end of the rotating shaft close to the limiting ring; a first gear is installed at the end of the moving rod away from the insertion block; a fixing frame is installed on the fixing seat; a driving motor is arranged on the fixing frame; a second gear is installed at the end face of the output shaft of the driving motor; ensuring the rotation effect of the limiting plate.

[0012] Preferably, when the moving rod contacts the rotating shaft, the insertion block completely enters the insertion groove, and at this time, the second gear meshes with the first gear; when the insertion block is farthest from the insertion groove, the rotation trajectory of the second gear does not intersect with the rotation trajectory of the first gear; enabling the second gear to operate smoothly.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the structural design of the anti-falling auxiliary device, the present utility model places the needle body to be installed in the placement groove at the top of the limit plate, applies a force to the limit frame, and the sliding block moves along the sliding groove accordingly. With the cooperation of the rolling beads in the pressing cavity, the pressing block moves upward along the telescopic cavity, the spring is compressed and generates a reaction force, so that the pressing block tightly presses on the needle body. As the limit frame moves, the sliding block is stuck into the inside of the card slot, realizing the clamping of the PIN needle on the limit plate. With the auxiliary cooperation of the jack, the phenomenon of the needle body falling during the installation process is avoided, and the time consumed for picking up and wiping the PIN needle is reduced. Then, the small motor in the structural cavity is started, and the screw rotates inside the screw hole, so that the lifting seat drives the limit plate to move upward to a suitable position, ensuring the smooth progress of the subsequent PIN needle installation operation.

[0024] A pressing cavity 408 is penetrated through the bottom of the pressing block 407; rolling beads 409 are rotatably installed on the top end surface of the inner wall of the pressing cavity 408 near the positions of both ends of the opening; placing grooves 410 are equidistantly opened on the acting structural surface of the limiting plate 401; jack holes 412 are opened on the top of the base 1; when the limiting plate 401 is in a vertical state, the center line of the placing groove 410 coincides with the center line of the corresponding jack hole 412; a needle body 6 is placed inside the placing groove 410; the spring 406 does not deform when not working, and at this time, the horizontal plane where the bottom end surface of the pressing block 407 is located coincides with the horizontal plane where the acting end surface of the limiting plate 401 is located; clamping grooves 411 are opened at both ends of the sliding groove 402; the width of the sliding block 403 is smaller than the opening width of the sliding groove 402; structural cavities 413 are opened on both sides inside the base 1; small motors 414 are installed inside the structural cavities 413; a screw rod 416 is installed on the top of the output shaft of the small motor 414; threaded holes 415 are symmetrically opened on the bottom end surface of the lifting seat 2; the screw rod 416 passes through the base 1 and is inserted into the threaded hole 415.

[0025] During operation, as a PIN needle in an electronic device or industrial device, common shapes are series such as four-pin needles and round needles, and additional fixing measures or anti-falling designs are required to ensure that the PIN needle does not accidentally loosen or fall off during transportation, installation, or use; when the above PIN needle is installed, the phenomenon of the needle body falling off will occur, causing the needle body to be contaminated, and picking up and wiping the needle body will take more time, resulting in a longer installation time for the entire needle body and affecting the installation efficiency of the PIN needle. This application acts through an anti-falling auxiliary device. The needle body 6 to be installed is placed in the placement groove 410 at the top of the limit plate 401. When a force is applied to the limit frame 404, the sliding block 403 moves along the sliding groove 402 accordingly. With the cooperation of the rolling beads 409 in the pressing cavity 408, the pressing block 407 moves upward along the telescopic cavity 405. The spring 406 is compressed and generates a reaction force, causing the pressing block 407 to tightly press on the needle body 6. As the limit frame 404 moves, the sliding block 403 is inserted into the internal of the card slot 411, realizing the clamping of the PIN needle on the limit plate 401. With the auxiliary cooperation of the jack 412, the phenomenon of the needle body falling off during installation is avoided. Then, the small motor 414 in the structure cavity 413 is started, and the screw 416 rotates inside the screw hole 415, causing the lifting seat 2 to drive the limit plate 401 to move upward to a suitable position, ensuring that the subsequent installation operation of the PIN needle can proceed smoothly.

[0026] Please refer to Figures 4-5 As shown, a fixed seat 501 is fixedly connected to one side structural surface of the lifting seat 2; a limit ring 502 is fixedly connected to the side of the fixed seat 501 close to the limit plate 401; a moving rod 503 is slidably installed inside the limit ring 502; an insertion block 504 is fixedly connected to the end of the moving rod 503 close to the limit plate 401; an insertion slot 505 is opened at the end of the rotating shaft 3 close to the limit ring 502; a first gear 506 is installed at one end of the moving rod 503 away from the insertion block 504; a fixed frame 507 is installed on the fixed seat 501; a driving motor 508 is arranged on the fixed frame 507; a second gear 509 is installed on the end face of the output shaft of the driving motor 508; when the moving rod 503 contacts the rotating shaft 3, the insertion block 504 completely enters the insertion slot 505, and at this time, the second gear 509 meshes with the first gear 506; when the insertion block 504 is farthest from the insertion slot 505, the rotation trajectory of the second gear 509 does not intersect with the rotation trajectory of the first gear 506;

[0027] During operation, the moving rod 503 on the limit ring 502 is pushed to make the insertion block 504 completely enter the insertion slot 505, and the first gear 506 meshes with the second gear 509. The driving motor 508 on the fixed frame 507 is started, and the second gear 509 rotates, causing the limit plate 401 to rotate to a suitable angle around the rotating shaft 3, facilitating the installation of PIN needles at different angles.

[0028] Working principle: As a PIN needle in electronic devices or industrial devices, common shapes are series such as four-pin needles and round needles, and additional fixing measures or anti-dropping designs are required to ensure that the PIN needle will not accidentally loosen or fall off during transportation, installation or use; when the above PIN needle is installed, the needle body may fall off, causing the needle body to be contaminated, and picking up and wiping the needle body will take more time, resulting in a longer installation operation time for the entire needle body, affecting the installation efficiency of the PIN needle. This application acts through an anti-dropping auxiliary device. The needle body 6 to be installed is placed in the placement groove 410 at the top of the limit plate 401. When a force is applied to the limit frame 404, the sliding block 403 moves along the sliding groove 402 accordingly. With the cooperation of the rolling beads 409 in the pressing cavity 408, the pressing block 407 moves upward along the telescopic cavity 405. The spring 406 is compressed and generates a reaction force, causing the pressing block 407 to tightly press on the needle body 6. As the limit frame 404 moves, the sliding block 403 snaps into the inside of the card slot 411, realizing the clamping of the PIN needle on the limit plate 401. Push the moving rod 503 on the limit ring 502, so that the insertion block 504 completely enters the insertion slot 505, and the first gear 506 meshes with the second gear 509. Start the drive motor 508 on the fixed frame 507, and the second gear 509 rotates, causing the limit plate 401 to rotate to an appropriate angle around the rotating shaft 3. With the auxiliary cooperation of the jack 412, the phenomenon of the needle body falling off during installation is avoided, reducing the time consumed for picking up and wiping the PIN needle. Then start the small motor 414 in the structure cavity 413, and the screw 416 rotates inside the screw hole 415, causing the lifting seat 2 to drive the limit plate 401 to move upward to an appropriate position, ensuring that the subsequent installation operation of the PIN needle can proceed smoothly.
