Description

Technical Field

[0001] The utility model relates to the technical field of ceiling fixers, in particular to a novel split firing pin tube. Background Art

[0002] In modern construction and woodworking, ceiling anchors are widely used as efficient and convenient hand tools. Using the fumes from firing blank cartridges as power, they rapidly drive nails into the building, achieving direct material consolidation. This technology not only improves work efficiency but also significantly reduces the manual labor required for traditional nailing.

[0003] However, existing ceiling mounts have some shortcomings, particularly in the design of their key component: the firing pin tube. Traditional firing pin tubes typically utilize a one-piece structure, primarily consisting of a pin sleeve and a seat sleeve. While this design ensures structural integrity and strength to a certain extent, it also presents several challenges:

[0004] 1. High cost of use: The striker barrel is susceptible to wear and tear during use, and the integrated design requires the entire striker barrel to be replaced if the striker barrel is damaged. This undoubtedly increases the user's cost of use and wastes the intact portion.

[0005] 2. Inconvenient Replacement: When the firing pin tube needs to be replaced, the user has to completely disassemble and assemble the ceiling fixture, a time-consuming and labor-intensive process that significantly reduces work efficiency. In addition, frequent disassembly and assembly may cause other components to loosen or become damaged, further increasing maintenance costs.

[0006] 3. Difficulty in maintenance: For some professional users, even if they have certain maintenance skills, it is difficult to carry out effective local repairs due to the complex structure of the integrated firing pin tube, and they can only choose to replace new parts.

[0007] In order to solve the above problems, it is necessary to develop a new firing pin tube design to improve the practicality and economy of the ceiling fixture. By introducing a split structure, the needle sleeve part and the seat sleeve part can be replaced independently, thereby simplifying the maintenance process and reducing the cost of use.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0028] The utility model provides a novel split firing pin tube.

[0029] In this embodiment, referring to Figure 1-4The new split firing pin tube includes a firing pin tube body 1, which includes a detachably connected seat cover part 2 and a needle cover part 3. A connecting hole 4 is provided on one end of the seat cover part, and a connecting column end 5 is provided on the end where the needle cover part is connected to the seat cover part. A connecting ring groove 6 is provided on the outer circle of the connecting column end 5, and a locking hole 7 is provided on the side of the connecting hole. A locking piece 8 is connected to the locking hole. After the connecting column is inserted into the locking hole, the locking piece is snapped into the above-mentioned connecting ring groove to fix the needle cover part and the seat cover part.

[0030] In the above technical solution, the needle sleeve and seat sleeve are designed as separate components, and the two are fixed together by the use of a connecting ring groove and a locking member. This split design allows the needle sleeve and seat sleeve to be replaced independently, reducing usage costs and simplifying maintenance. Furthermore, the locking member ensures a secure and reliable connection, improving the stability and durability of the overall structure and facilitating assembly and disassembly.

[0031] Example 1 of the locking member: The locking member is a "U"-shaped pin, and an arc-shaped groove 9 for installing the "U"-shaped pin is provided on one side of the connecting hole. There are two locking holes, which are symmetrically arranged at both ends of the arc-shaped groove. After the "U"-shaped pin is inserted into the locking hole, it can be stuck into the above-mentioned connecting ring groove to realize a fixed connection between the needle sleeve part and the seat sleeve part.

[0032] The "U"-shaped latch design allows for quick installation and removal, making operation simple and convenient. The symmetrically arranged locking holes and arc-shaped grooves enhance the stability of the connection, ensuring a firm connection between the needle sleeve and the seat sleeve, and improving reliability and safety.

[0033] In addition, the use of U-shaped bilaterally symmetrical pins can better fix the stability of the needle sleeve part and prevent it from falling off. At the same time, it can also keep the needle sleeve part in a vertical state, thereby improving product performance.

[0034] When disassembling and assembling, just pull out the pin to separate the needle sleeve part and the seat sleeve part, which makes it more convenient to replace the firing pin sleeve and greatly reduces the user's use cost.

[0035] Specifically, the locking hole extends to the bottom of the seat cover portion on the other side of the arc-shaped groove.

[0036] The design of extending the locking hole to the bottom of the seat cover increases the force-bearing area of the locking member, further enhancing the stability of the connection. This design also prevents the "U"-shaped latch from loosening due to vibration during operation, improving the durability and stability of the overall structure.

[0037] Example 2 of the locking piece: the locking piece is a pin column, and the locking hole is a screw hole, which is symmetrically arranged on the upper and lower sides of the connecting hole. After the pin column is threadedly connected to the locking hole, the top of the pin column is pressed tightly in the connecting ring groove to achieve a fixed connection between the needle sleeve part and the seat sleeve part.

[0038] The threaded connection between the pin and the screw hole provides a stronger fixing force, ensuring a tight connection between the needle sleeve and the seat sleeve. This design not only improves the reliability of the connection, but also makes disassembly and assembly easier by simply unscrewing the pin from the screw hole.

[0039] Specifically, the latch post includes a fixed section 10 that is inserted into the connecting ring groove and a threaded section 11 that is connected to the locking thread.

[0040] The latch consists of a fixed section and a threaded section. The fixed section snaps into the connecting ring groove, providing a stable mechanical lock; the threaded section is tightened via a threaded connection. This design ensures a secure connection while facilitating quick installation and removal, improving work efficiency.

[0041] Specifically, the top of the threaded section is provided with a disassembly structure 12.

[0042] The assembly and disassembly structure (e.g., hexagonal head, cross slot, etc.) at the top of the threaded section facilitates tightening or loosening with tools (e.g., wrenches, screwdrivers, etc.), further simplifying the installation and disassembly process. This design not only improves user convenience, but also reduces the risk of damage caused by improper manual operation and extends the tool's service life.

[0043] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
