Description

Technical Field

[0001] This utility model relates to the field of firing pin technology, and in particular to a novel firing pin that can be quickly replaced. Background Technology

[0002] A dispensing device is used for bonding, potting, coating, and sealing in the production of handicrafts. The impact valve is a crucial component of this device. Its structure generally includes a valve body, a dispensing needle with a steel needle, and an impact needle housed within the valve body. An impact needle seat is mounted on the valve body, and a spray cap is rotatably mounted on the valve body. The steel needle on the spray cap can be replaced, or the entire spray cap can be replaced. During use, the dispensing material is forced into the valve body through a connecting pipe connected to the material source, then passes through the valve body and the dispensing needle, and is ejected from the steel needle. When the impact valve is closed, high-pressure gas propels the impact needle forward, causing its tip to abut against the impact needle seat on the valve body, blocking the connection between the seat and the needle and preventing material from exiting through the steel needle. Traditional equipment often suffers from difficulty in disassembly and replacement, reducing ease of use. Therefore, we have redesigned a new type of impact needle that allows for quick replacement.

[0010] Compared with related technologies, the novel quick-replaceable firing pin provided by this utility model has the following beneficial effects:

[0011] 1. This utility model provides a quick-replaceable new type of firing pin. A locking block inside the locking disc is directly inserted into the insertion groove. Rotating the main body of the locking disc causes the locking block to directly engage with the insertion groove. At this time, the compression spring inside the auxiliary compression groove automatically abuts against the position of the compression limiting disc. The compression limiting disc, acting as a locking mechanism, assists in securing the locking block. The locking connecting post is then directly inserted into the pin groove. For subsequent disassembly, simply rotate the locking disc to move the locking block from the insertion groove into the insertion groove, and remove it. Disassembly is convenient, and different specifications of firing pin bodies can be replaced. A protective ball is provided at the top of the firing pin body to effectively protect the top of the firing pin body and improve the service life of the device.

[0012] 2. This utility model provides a new type of quick-replaceable striking pin. When the striking pin body is not in use, the auxiliary rotating handle can be rotated to rotate the transmission arm onto the connecting limit plate, thereby installing the connecting limit thread into the inside of the locking control rod. The connecting limit thread limits the entire main body mounting column, thus achieving a limiting placement effect on the striking pin body. When not in use, the connecting limit thread can be directly disassembled when needed. Attached Figure Description

Detailed Implementation

[0018] Example 1:

[0019] Please see Figure 1-4 This utility model provides a technical solution: a novel quick-replaceable firing pin, comprising a main mounting post 1, a snap-fit ​​connecting post 2 fixedly connected to one bottom end of the main mounting post 1, a locking disc 3 detachably mounted on one side surface of the snap-fit ​​connecting post 2, a firing pin body 4 fixedly connected to one bottom end of the locking disc 3, a protective ball 5 fixedly connected to one top end of one side of the firing pin body 4, a pin groove 6 provided inside the locking disc 3, a snap-fit ​​block 7 fixedly connected to the top surface of the inside of the locking disc 3, and an insertion groove 8 provided on the bottom edge surface of one side of the snap-fit ​​connecting post 2. A snap-fit ​​groove 9 is provided on the side of the connecting post 2 near the insertion groove 8. An auxiliary extrusion groove 10 is provided inside the bottom end of one side of the snap-fit ​​groove 9. An extrusion fixing spring 11 is fixedly connected to the bottom end of the auxiliary extrusion groove 10. An extrusion limiting plate 12 is fixedly connected to the top end of one side of the extrusion fixing spring 11. The cross-sectional length of the extrusion limiting plate 12 is greater than the cross-sectional width of the auxiliary extrusion groove 10. The positions of the snap-fit ​​block 7 and the insertion groove 8 correspond one-to-one. The connection relationship between the snap-fit ​​block 7 and the snap-fit ​​groove 9 is a movable snap-fit. The connection relationship between the snap-fit ​​block 7 and the extrusion limiting plate 12 is an extrusion snap-fit ​​connection.

[0020] In the implementation scheme, the latching block 7 inside the locking disc 3 is directly inserted into the insertion groove 8. By rotating the main body of the locking disc 3, the latching block 7 is directly latched into the latching groove 9. At this time, the compression fixing spring 11 inside the auxiliary compression groove 10 will automatically abut against the position of the compression limiting disc 12. The compression limiting disc 12 assists in the fastening effect of the latching block 7. At this time, the latching connecting post 2 is directly inserted into the pin groove 6. When disassembly is required later, the locking disc 3 is rotated to move the latching block 7 inside the latching groove 9 into the insertion groove 8, and it can be taken out from the insertion groove 8. Disassembly is convenient, and different specifications of the firing pin body 4 can be replaced. A protective ball 5 is set at the top of the firing pin body 4, which can effectively protect the top of the firing pin body 4 and improve the service life of the device.

[0021] Example 2:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a novel quick-replaceable firing pin, comprising a locking control rod 13 fixedly installed on the top of one side of a main mounting post 1, a locking thread groove 14 formed inside one side of the locking control rod 13, the locking thread groove 14 penetrating the interior of the locking control rod 13 and the main mounting post 1, the main mounting post 1 and the locking control rod 13 being connected, a connecting limiting thread 15 detachably installed inside the locking thread groove 14, a connecting limiting top plate 16 fixedly connected to one side of the connecting limiting thread 15, and the connecting limiting top plate 16... A connecting rod 17 is fixedly connected to one top side of the auxiliary rotating handle 19. A transmission arm 18 is rotatably connected to one top side of the connecting rod 17. An auxiliary rotating handle 19 is fixedly connected to one bottom surface of the transmission arm 18. A friction block 20 is fixedly installed on one side surface of the auxiliary rotating handle 19. The locking thread groove 14 and the connecting limit thread 15 are connected by a threaded connection. The transmission arm 18 and the connecting limit top plate 16 are connected by a transmission connection. There are several friction blocks 20, which are distributed in a circular pattern on one side surface of the auxiliary rotating handle 19.

[0023] In the implementation plan, when the firing pin body 4 is not in use, the auxiliary rotating handle 19 can be rotated to rotate the transmission arm 18 onto the connecting limit plate 16, thereby installing the connecting limit thread 15 into the inside of the locking control rod 13. The connecting limit thread 15 limits the entire body mounting column 1, thus achieving the limiting placement effect of the firing pin body 4. When not in use, the connecting limit thread 15 can be directly disassembled when needed.

[0024] Working principle:

[0025] By setting the latching block 7 inside the locking disc 3 to be directly inserted into the insertion groove 8, and rotating the main body of the locking disc 3, the latching block 7 is directly latched into the latching groove 9. At this time, the compression fixing spring 11 inside the auxiliary compression groove 10 will automatically abut against the position of the compression limiting disc 12. The compression limiting disc 12 assists in the fastening effect of the latching block 7 on the main body of the latching block 7. At this time, the latching connecting post 2 is directly inserted into the pin groove 6. When disassembly is required later, simply rotate the locking disc 3 to move the latching block 7 inside the latching groove 9 into the insertion groove 8, and remove it from the insertion groove 8. Disassembly is convenient, and different specifications of the firing pin body 4 can be replaced. A protective ball 5 is set at the top of the firing pin body 4, which can effectively protect the top of the firing pin body 4 and improve the service life of the device.

[0026] When the main body 4 of the firing pin is not in use, the auxiliary rotating handle 19 can be rotated to rotate the transmission arm 18 onto the connecting limit plate 16, thereby installing the connecting limit thread 15 into the inside of the locking control rod 13. The connecting limit thread 15 limits the entire main body mounting column 1, thus achieving the limiting placement effect of the firing pin main body 4. When not in use, the connecting limit thread 15 can be directly disassembled when needed.
