Abstract

The utility model relates to a shoot nail for a nail gun. A nail bar of the shoot nail is sheathed with a positioning slide sleeve to accurately control the striking depth. In addition, the nail bar is also sheathed with a plastic or steel guide sleeve, a plastic antiskid sleeve, etc. The utility model is especially suitable for using in a nut fixed locking theftproof device which is designed by the applicant of the utility model. The structure of the utility model has no influence on the intensity of nailing, and the reliability of firing can be enhanced.

Description

May command is driven into the nailing of the degree of depth

The utility model relates to the nailing that nail gun is used.

The nailing tightening technology is to utilize nail gun percussion nail shooting pill, makes powder burning, gives off energy, and nailing is followed closely on concrete, brick body or iron and steel.After present nailing is injected object, be deep into nail tail side always and end.When not needing nailing all to inject, the existing uncontrollable penetrating depth of nailing.The applicant discloses a kind of nut and has locked alarm admittedly in Chinese patent CN94214635, nailing accurately can be squeezed into the point of attachment of nut and bolt, makes the two that relative movement can't take place again, thereby reaches the antitheft purpose of solid lock.The nailing that this alarm uses at first still is conventional construction, and shortcoming also is to be driven into the degree of depth can not control, and when being driven into deeply, can cause the screw thread crack, reduction in strength.A kind of stepped shape nailing is arranged at present, be made up of for two sections thin neck and thick neck, though there is set a distance to inject function, this nailing is in thick, thin very easily brittle failure of neck connecting part, and intensity is low, and the percussion success rate is low, so the difficulty of use.

The purpose of this utility model is to avoid above-mentioned difficulties, the nailing that provides a kind of may command to be driven into the degree of depth, and do not influence the intensity of following closely body, thus the percussion success rate is improved.

Solution of the present utility model is: one in cover can block the locating slide sleeve of nail tail on the nail bar of nailing, is driven into the degree of depth with control.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the sectional arrangement drawing of this nailing.

Fig. 2 is the front view of anti-sliding sleeve.

Referring to Fig. 1, on the nail bar 1 of nailing, be with locating slide sleeve 3, can slide relative between sliding sleeve and the nail bar.When injecting object, nail tail 2 is blocked by sliding sleeve 3 at nail bar 1, thereby can not continue in the object that deep quilt follows closely.By changing the length controlled system penetrating depth of sliding sleeve.Sliding sleeve is injected darker in short-term; When sliding sleeve is long, inject more shallow.

As figure, the flange 5 that play the guiding role is arranged at the tail end of locating slide sleeve 3.

In order to improve the stability of nailing in the percussion process, be provided with the guide sleeve 6 of plastics or steel at nail bar 1 rear portion.The diameter of guide sleeve and slip-on flange 5 are basic identical.

In addition, on nail bar 1, also be provided with the anti-sliding sleeve 8 of plastics, on anti-sliding sleeve periphery, be furnished with a plurality of flexible projections 9, see Fig. 2, can in gun barrel, play the swelling effect, produce frictional force, thereby prevent that nailing from arbitrarily sliding in gun barrel.

This nailing is compared with traditional nailing, and topmost advantage is can accurately control to be driven into the degree of depth, And do not affect the intensity of nailing, be particularly suitable for device for preventing theft of nut and use, can greatly improve and hit The reliability of sending out.

Claims

1, may command is driven into the nailing of the degree of depth, comprises nail bar (1) and nail tail (2), it is characterized in that: be with the locating slide sleeve (3) that can block the nail tail on nail bar (1), be driven into the degree of depth with control.

2, nailing as claimed in claim 1 is characterized in that: the tail end of locating slide sleeve (3) has the flange (5) that play the guiding role.

3, nailing as claimed in claim 1 or 2 is characterized in that: the guide sleeve (6) that is provided with plastics or steel at the rear portion of nail bar (1).

4, nailing as claimed in claim 1 or 2 is characterized in that: be provided with the anti-sliding sleeve (8) of plastics on nail bar (1), be furnished with a plurality of flexible projections (9) on anti-sliding sleeve periphery, in case nailing arbitrarily slides in gun barrel.
