Bushing and nailing tube set using the same

The present invention relates to a bushing provided in a nail gun having an insured structure, and a nailing tube set using the same.

The conventional nail gun structure can be referred to the TW I361128 patent, which mainly includes a gun body and a safety device disposed on the gun body; the gun body includes a nailing tube at the front end of the gun body and is located inside the gun body and has a front end An abutting portion of the elastic body, and a convex portion disposed on the outer peripheral surface of the nailing tube; the safety device includes a safety member disposed on the nailing tube and a positioning member; the safety member includes a pressing portion, a buckle portion and a first positioning portion at the rear end of the safety member; the pressing portion is located at the front end of the safety member, and extends to the nozzle of the nailing tube to push a nail to be pushed; the buckle portion is used for the topping The securing member is retained on the nailing tube; the positioning member is inserted into the gun body, and includes a second positioning portion and a tripod; and the second positioning portion is detachably connected to the first positioning portion. Thereby, when the pressing portion is in the top to be determined, the safety member can be pushed to slip and the nail gun can be released, so that the nail gun can be fired.

The nailing tube is provided with a cutting groove, and the safety piece is provided with a sliding block for extending into the cutting groove, so that the safety piece can slide along the cutting groove relative to the nailing tube; however, the section of the nailing tube The groove design will reduce the overall structural strength. After use, the nail tube is prone to structural damage or deformation, and thus cannot be used normally.

In view of the above problems, the main purpose of the present invention is to provide a bushing structure for mounting a nailing tube of a nail gun to improve the structural strength of the conventional nailing tube and to improve its durability.

In order to achieve the above object, the present invention provides a bushing for a nailing tube mounted on a nail gun, the bushing having a first end and a second end, the first end facing away from one end of the nailing tube And a pressing portion, the second end is provided with a positioning portion for pushing against the nail gun, wherein the bushing is provided with a sleeve portion having a sleeve hole between the first end and the second end, The bushing is slidably sleeved by the sleeve portion, and the bushing is slidable relative to the nail tube to selectively release the nail gun from being secured to the stapler status.

Therefore, compared with the structural strength problem which is derived from the processing of the nailing tube for the processing of the cutting groove, the design allows the bushing to be slidably disposed on the nailing tube through the design of the socket portion, so that there is no need to shoot again. The nail tube is used for destructive groove processing to maintain the overall structural strength and enhance durability.

The structural features of the present invention and the intended effects thereof are described in the following preferred embodiments, and are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 3, the nailing tube set of the present invention is provided with a nail gun having an anti-fire safety device, and the nailing tube set includes a nailing tube 1 and a bushing 2.

The nailing tube 1 is mounted on the front end of the nail gun and has a nail path 11 . The nail channel 11 is provided with a guiding groove 111 for guiding the nail pin, and the guiding groove 111 is used for guiding the nail to be fired. The nail can be oriented in the direction of the firing, wherein the length, depth and size of the guiding groove can be matched according to the type of nail to be hit. The bushing 2 has a first end and a second end. The first end faces away from one end of the nail tube 1 and is provided with a pressing portion 21, and the second end is provided with a positioning for pushing against the nail gun. The sleeve portion 2 is provided with a sleeve portion 23 having a sleeve hole between the first end and the second end, and the sleeve 2 is slidably sleeved by the sleeve portion 23 The nail tube 1 (the shape of the socket portion and the nail tube can be designed in a matching manner, as in the embodiment, the cylindrical nail tube is used to make the sleeve hole of the socket portion have a circular hole shape), and the sleeve 2 can be slipped. The bushing 2 is designed to be slidable relative to the nail cannula 1 to selectively disengage the nail gun from being in a squeezable state when used in a nail gun having a safety structure. In order to limit the sliding range of the bushing, a limiting member may be arranged on the nail gun or the nailing tube for the positioning limit of the positioning portion of the bushing (the structural design of the limiting member and the positioning portion can be matched) For example, the positioning portion of the embodiment is provided with a set of holes for the sleeve.

In the above embodiment, the bushing 2 is further provided with an insertion portion 24 for inserting the nail tube 1. The insertion portion 24 extends from the first end of the bushing 2 to the second end. The insertion portion 24 is inserted into the nail channel 11 of the nailing tube 1 (the insertion portion and the nail channel can be designed in a size or shape), and the socket portion 23 surrounds the insertion portion 24 to make the nail The tube 1 is inserted between the insertion portion 24 and the socket portion 23; and when the sleeve 2 is slid relative to the needle tube 1, the insertion portion 24 is kept slipped in the nail channel 11 to The stability of the sliding of the bushing 2 is improved.

Therefore, when installed in the nail gun, the user needs to press the pressing portion 21 against the top. If the workpiece of the nail gun is to be driven, the nail tube bushing 2 is moved backward (moving in the direction of the nail tube) to release the insurance by the slip of the nail tube bushing 2, and the nail gun is The state of the nail can be fired to ensure that the nail gun can only be fired when it is against the object to be nailed.

Moreover, in order to ensure that the nail gun bushing can maintain the same angle during the slipping process, the bushing can be matched with the structure of the nailing tube without relative rotation. As in this embodiment, the bushing 2 has a concave arc-shaped contact surface 25 (refer to FIG. 1 and FIG. 1A), and the nailing tube 1 is provided with a substantially planar sliding surface 12, the bushing 2 The contact surface 25 is in contact with the sliding surface 12 and is slidable along the sliding surface 12, and the nailing tube 1 limits the bushing 2 from relative rotation by the sliding surface 12, that is, the bushing 2 abuts The sliding surface 12 can only slide in the direction of the sliding surface 12 and maintain the same angle. Of course, in other embodiments, the bushing and the nailing tube may be provided with corresponding sliding grooves, or the sleeve portion and the nailing tube for the sleeve portion may be non-circular. It is also possible to achieve the function of making the two unable to rotate relative to each other.

Therefore, compared with the structural strength problem derived from the design and processing of the grooved tube by the conventional dewaxing casting, the design allows the bushing to be slidably disposed on the nailing tube through the design of the socket portion. The nail tube does not need to be destructively grooved to maintain the overall structural strength and improve durability; furthermore, it has the advantage of low production cost due to the reduction of the processing of the nailing tube; The design of the design can improve the stability of the bushing slip, so that the nail gun has a good and stable nailing effect.

Summarizing the above, the bush of this creation is not only structurally innovative, but also highly progressive, in line with the relevant provisions of the Patent Law, and filed a patent application in accordance with the law, so that the 钧 早 核 早 早 早 早 早 。 。 。 。 。 。 。 。 。 。 。 。 。
