Description

Technical Field

[0001] The utility model relates to the technical field of ceiling nail fixing devices, in particular to a firing pin tube. Background Art

[0002] The ceiling nailer is a product of modern nail-shooting fastening technology. It can fire nails and belongs to direct consolidation technology. It is an essential hand tool for carpentry, construction, etc. When the nailer is working, it uses the gunpowder gas produced by firing blank bullets as power to drive nails into the building.

[0003] The firing pin tube is an important part of the firing mechanism of the ceiling nailer. During assembly, the firing pin tube is sleeved outside the firing pin tube and the firing pin seat, and the open end surface of the firing pin seat sleeve of the firing pin tube abuts against the firing cap (such as Figure 3 As shown in the figure, since the firing pin tube is directly mounted outside the firing pin tube, the firing pin tube tends to rotate after shooting, which affects the stability of the ceiling nail fixer. To solve the above technical problems, the present application proposes a firing pin tube that is mutually limited with the firing cap and a ceiling nail fixer equipped with the firing pin tube.

[0004] For related prior art, please refer to the application of our company, such as a mini ceiling nail fixer disclosed in application number 2023222833144. Utility Model Content

[0010] The present application also provides a ceiling nail fixer including a firing pin tube, including a main sleeve, a firing pin, a firing pin seat, an excitation spring, a firing cap, an excitation sleeve and the above-mentioned firing pin tube, and the firing cap can be inserted into the groove of the firing pin tube.

[0011] Specifically: a slag discharge hole is provided in the rear part of the excitation sleeve, and a connecting thread for connecting with a handle is provided on the outer wall of the rear part of the excitation sleeve.

[0012] The beneficial effect of the utility model is that a slot is provided on an opening at one end of the firing pin sleeve of the firing pin tube. When in use, the firing cap is inserted into the slot to limit the rotation of the firing pin tube, thereby avoiding the rotation of the firing pin tube during use and improving the firing stability of the ceiling nail fixer.

[0013] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] The utility model provides a firing pin tube.

[0022] In this embodiment, refer to Figure 1-3 The firing pin tube comprises a firing pin sleeve portion 1 and a firing pin seat sleeve portion 2. A slot 3 is provided on an opening of the firing pin seat sleeve portion 2 away from the firing pin sleeve portion 1.

[0023] In the above technical solution, a slot is provided on an opening at one end of the firing pin sleeve of the firing pin tube. When in use, the firing cap is inserted into the slot to limit the rotation of the firing pin tube, thereby avoiding the rotation of the firing pin tube during use and improving the firing stability of the ceiling nail fixer.

[0024] When used specifically, Figure 2 As shown, the firing cap is inserted into the slot to limit the rotation of the firing pin tube.

[0025] Specifically, there are one or two slots.

[0026] Among them, one or more slots can be provided, but since there is only one firing cap, generally only one slot is provided. When two slots are provided, they can be selectively assembled for easy assembly. Preferably, one or two slots are provided.

[0027] Specifically, the slotted arc structure or "U"-shaped structure.

[0028] Specifically, the firing pin seat cover portion has an extension section 4 on one end away from the firing pin cover portion, and the slot 3 is located on the extension section 4.

[0029] Due to the setting of the slot, the actual effective length of the firing tube will be indirectly reduced, and the pressure of the firing spring will be increased. The present application increases the length of the firing tube by adding an extension section to the original length of the firing tube, thereby ensuring the original firing performance. Moreover, by adding the extension section, after firing, the firing tube is subjected to the rebound force and can counteract the end face of the firing tube earlier, reducing the recoil force, effectively reducing the compression length of the trigger spring, and increasing the service life of the firing spring.

[0030] The present application also provides a ceiling nail fixer including a firing pin tube, including a main sleeve 5, a firing pin 6, a firing pin seat 7, an excitation spring 8, a firing cap 9, an excitation sleeve 10 and the above-mentioned firing pin tube, and the firing cap can be inserted into the groove 3 of the firing pin tube.

[0031] The firing pin tube provided with a slot can be assembled and used with the firing assembly of the original structure, thereby improving the performance of the ceiling nail fixing device.

[0032] Specifically: a slag discharge hole 11 is provided in the rear part of the excitation sleeve, and a connecting thread 12 for connecting with a handle is provided on the outer wall of the rear part of the excitation sleeve.

[0033] The slag discharge hole is used for slag discharge, and is used in conjunction with a handle with slag discharge function to improve the slag discharge capacity of the ceiling nailer.

[0034] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the utility model concept of the utility model is not limited to this utility model. Any modification using the utility model concept will be included in the scope of protection of this patent right.
