A PCB board rapid splicing device with a self-locking mechanism

Abstract

This utility model belongs to the field of circuit board technology, and in particular to a PCB board quick splicing device with a self-locking mechanism. It includes a base one and a base two. A PCB board one is mounted on the upper surface of the base one, and a PCB board two is mounted on the upper surface of the base two. Insert rods are fixedly connected to both sides of the middle of the lower surface of the base one, and connecting cylinders are installed on both sides of the middle of the lower surface of the base two. This utility model connects the base one and base two together, allowing the insert rods to be inserted into the connecting cylinders. The surface of the fixed hemisphere passes through a slider. Because one side of the slider has an inclined surface, the curved surface of the fixed hemisphere presses against the inclined surface of the slider, causing the slider to drive the connecting rods to slide. With the cooperation of a spring two, the connecting rods can be reset, and the outer wall of the slider hooks onto the straight surface of the fixed hemisphere, thus enabling the quick splicing and installation of the base one and base two.

[0010] Compared with the prior art, this utility model provides a PCB board rapid splicing device with a self-locking mechanism, which has the following beneficial effects:

[0011] 1. This PCB board quick splicing device with a self-locking mechanism connects base one and base two together, allowing the insertion rod to be inserted into the connecting cylinder. The surface of the fixed hemisphere passes through the slider. Since one side of the slider has an inclined surface, the arc surface of the fixed hemisphere will press against the inclined surface of the slider, causing the slider to drive the connecting rod to slide. With the cooperation of spring two, the fixed hemisphere passes through the slider, and the connecting rod can be reset. Then, the outer wall of the slider hooks onto the straight surface of the fixed hemisphere, thus realizing the quick splicing and installation of base one and base two.

[0012] 2. This PCB board quick splicing device with a self-locking mechanism, through the setting of a tension spring, can pull the slide rod upward, thereby causing the first fixing frame to pull the pull plate, which in turn causes the second fixing frame to pull the slide plate outward within the fixing block. The slide plate drives the first support rod to slide outward, which in turn causes the positioning rod connected to it to lock into the through hole of the connecting plate, thereby achieving the locking of the connecting cylinder, ensuring the fixed state after splicing, and avoiding the problem of the base becoming loose during long-term use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please see Figure 1-6 In this embodiment: a PCB board quick splicing device with a self-locking mechanism includes a base 1 and a base 2. A PCB board 3 is installed on the upper surface of the base 1, and a PCB board 4 is installed on the upper surface of the base 2. Insert rods 5 are fixedly connected to both sides of the middle part of the lower surface of the base 1, and connecting cylinders 6 are installed on both sides of the middle part of the lower surface of the base 2. The outer wall of the insert rod 5 is slidably connected to the inside of the connecting cylinder 6. A fixed hemisphere 8 is fixedly connected to one end of the insert rod 5. A fixed cylinder 10 is fixedly connected to one side of the outer wall of the connecting cylinder 6. A connecting rod 11 is slidably connected to the inner wall of the fixed cylinder 10. A slider 12 is fixedly connected to one end of the connecting rod 11. One side of the slider 12 is hooked to one side of the fixed hemisphere 8. A spring 2 14 is sleeved on the outer wall of the connecting rod 11. A locking component 7 is installed on the outer wall of the connecting cylinder 6. The locking component 7 is installed on the lower surface of the base 2.

[0022] In this embodiment, PCB board 3 and PCB board 4 are respectively installed on base 1 and base 2. When these two PCB boards need to be spliced, base 1 and base 2 are joined together, so that the insert rod 5 on the lower surface of base 1 can be inserted into the connecting cylinder 6 on the lower surface of base 2. The fixed hemisphere 8 at one end of the insert rod 5 will pass through the slider 12. The inclined surface 13 on one side of the slider 12 is set, and the arc surface of the fixed hemisphere 8 cooperates with the inclined surface 13 on one side of the slider 12, so that the slider 12 can be squeezed, and the connecting rod 11 can slide in the fixed cylinder 10. When the fixed hemisphere 8 has completely passed the slider 12, the connecting rod 11 can be reset under the cooperation of spring 2 14, so that the slider 12 can hook one side of the fixed hemisphere 8, thereby fixing the position of the insert rod 5 in the connecting cylinder 6, so that base 1 and base 2 can be spliced ​​quickly.

[0023] Furthermore, the locking assembly 7 includes a fixing rod 701, one end of which is fixedly connected to the lower part of one end of the connecting cylinder 6. A fixing block 702 is fixedly connected to the upper surface of the fixing rod 701. A sliding rod 703 is slidably connected to the inner wall of the fixing rod 701. The outer wall of the sliding rod 703 is slidably connected to the inside of the fixing block 702. Fixing brackets 1 and 2 are fixedly connected to both sides of the upper part of the sliding rod 703. Sliding plates 705 are slidably connected to both sides of the inner wall of the fixing block 702. Fixing brackets 2 and 3 are fixedly connected to the upper part of adjacent surfaces of the sliding plates 705. Fixing brackets 1 and 2 are connected by a pull plate 707. Support rods 1 and 708 are fixedly connected to the middle of the far surfaces of the sliding plates 705. The outer wall of the support rod 708 is slidably connected to both sides of the fixed block 702. The far ends of the support rod 708 are fixedly connected to the positioning rods 709. The lower surface of the base 2 is fixedly connected to the connecting plate 710. The surface of the connecting plate 710 is provided with a through hole 711. The outer wall of the positioning rod 709 is locked in the inner wall of the through hole 711. The upper inner surface of the fixed block 702 is fixedly connected to the support rod 712. The outer wall of the support rod 712 is fitted with a tension spring 713. The inner wall of the slide rod 703 is slidably connected to the outer wall of the support rod 712. One end of the tension spring 713 is fixedly connected to the top of the slide rod 703. The other end of the tension spring 713 is fixedly connected to the upper inner surface of the fixed block 702. The outer wall of the support rod 708 is fitted with a spring 714.

[0024] The tension spring 713 pulls the slide bar 703 upward, which in turn causes the first fixing bracket 704 to pull the pull plate 707. This causes the second fixing bracket 706 to pull the slide plate 705 outward within the fixing block 702. The slide plate 705 then drives the first support rod 708 outward, which in turn causes the positioning rod 709 connected to it to engage in the through hole 711 of the connecting plate 710. This locks the connecting cylinder 6, ensuring a fixed state after splicing and preventing the base from loosening during long-term use.

[0025] Furthermore, a limiting block 18 is fixedly connected to one side of the upper surface of the connecting cylinder 6, and a limiting groove 17 is opened on both sides of the middle part of the lower surface of the base 2. The outer wall of the limiting block 18 is slidably connected to the inner wall of the limiting groove 17; a connecting sleeve 9 is sleeved on the outer wall of the insertion rod 5, and inclined surfaces 13 are provided on both sides of the outer wall of the connecting sleeve 9.

[0026] In this process, by pulling down the tension spring 713, with the cooperation of the first fixing frame 704, the pull plate 707, and the second fixing frame 706, the slide plate 705 can slide inward simultaneously, thereby allowing the positioning rod 709 to disengage from the through hole 711 of the connecting plate 710. Then, the connecting cylinder 6 is pushed, causing the limiting block 18 to slide within the limiting groove 17, thereby driving the slider 12 to move. The inclined surface 13 on one side of the slider 12 passes through the connecting sleeve 9, allowing it to hook onto one side of the connecting sleeve 9. Then, by pulling the connecting cylinder 6 back, the slider 12 can drive the connecting sleeve 9 to slide on the outer wall of the insertion rod 5. The maximum diameter of the connecting sleeve 9 is the same as the diameter of the fixed hemisphere 8, and both sides of the connecting sleeve 9 have inclined surfaces 13, which allows the slider 12 to disengage from the fixed hemisphere 8, thereby allowing the insertion rod 5 to disengage from the connecting cylinder 6, and allowing the base 1 and base 2 to be disassembled.

[0027] Furthermore, both sides of the outer wall of base 1 are fixedly connected with a locking block 15, and both sides of the lower surface of base 2 are provided with a locking groove 16, with the outer wall of the locking block 15 locked in the inner wall of the locking groove 16.

[0028] When base 1 and base 2 are assembled, the locking block 15 will be locked into the locking slot 16, thereby enhancing the positioning and stability between the bases and avoiding displacement or loosening that may occur during the assembly process.

[0029] Preferably, guide grooves 19 are provided on both sides of the upper and lower surfaces of the fixed block 702, and guide blocks 20 are fixedly connected to the upper and lower surfaces of the slide plate 705. The outer wall of the guide block 20 is slidably connected to the inner wall of the guide groove 19.

[0030] The working principle and usage process of this utility model: PCB board 1 3 and PCB board 2 4 are respectively installed on base 1 and base 2. When these two PCB boards need to be spliced, base 1 1 and base 2 2 are joined together, and the locking block 15 is locked into the slot 16, thereby enhancing the positioning and stability between the bases and avoiding possible displacement or loosening during splicing. Simultaneously, it allows the insert rod 5 on the lower surface of base 1 1 to be inserted into the connecting cylinder 6 on the lower surface of base 2 2. The fixed hemisphere 8 at one end of the insert rod 5 passes through the slider 12. Through the inclined surface 13 on one side of the slider 12, the arc surface of the fixed hemisphere 8 cooperates with the inclined surface 13 on one side of the slider 12, thereby squeezing the slider 12 and causing the connecting rod 11 to slide within the fixed cylinder 10. When the fixed hemisphere 8 has completely passed through... After passing through slider 12, with the cooperation of spring 14, connecting rod 11 can be reset, allowing slider 12 to hook onto one side of fixed hemisphere 8, thus fixing the position of insert rod 5 inside connecting cylinder 6, enabling quick splicing of base 1 and base 2. Through the setting of tension spring 713, sliding rod 703 can be pulled upward, thereby causing fixed bracket 704 to pull pull plate 707, which in turn causes fixed bracket 706 to pull slide plate 705 outward within fixed block 702. Slide plate 705 drives support rod 708 outward, which in turn drives the positioning rod 709 connected to it to engage in through hole 711 of connecting plate 710, thus locking connecting cylinder 6, ensuring the fixed state after splicing, and preventing the base from loosening during long-term use.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
