Abstract

(57) [Summary] [Purpose] To provide a nozzle that can be reused even if it is bent by an external force. [Structure] A cone-shaped base 1, a plastic cone-shaped member 2 externally fitted to the front end of the base 1 in a state of protruding from the mouth 1a of the base 1, and wound around the peripheral surface of the cone-shaped member 2. And a substantially conical coil spring 3 attached thereto. [Effect] Cone-shaped member 2 even if external force is applied near the tip
When the cone-shaped member 2 is once deformed by an external force and the external force is removed, the shape of the cone-shaped member 2 is restored by the elastic force of the coil spring 3. Therefore, even if it is bent once by an external force, it can be used again.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nozzle used when filling a caulking material or the like into the gap.

[0002]

[Prior art]

 Conventionally, in order to assemble the floor panel 9 shown in FIG. 3, a caulking material (not shown) is applied to the notch 8a of the joist 8 using a metal nozzle (not shown), and the caulking material is used to apply the caulking material. 8 and the frame body 7 were adhered.

[0003]

[Problems to be solved by the device]

 However, the joists 8 are conveyed by a conveyor (not shown) during the production process, and the joists 8 may come into contact with the nozzles due to the dimensional error of the joists 8 or the displacement of the joists 8, and the nozzles may bend. there were. In such a case, the metal nozzle is plastically deformed and cannot be used later.

An object of the present invention is to provide a nozzle that can be reused even if it is bent by an external force.

[0005]

[Means for Solving the Problems]

 The nozzle of this invention comprises a cone-shaped base, a cone-shaped member and a coil spring. The cone-shaped member is made of plastic and is fitted onto the tip of the base with the tip protruding from the mouth of the base. The coil spring has a substantially conical shape and is wound around the peripheral surface of the conical member.

[0006]

[Action]

 In the nozzle of this invention, a plastic cone-shaped member is externally fitted to the tip of the mouthpiece with the tip protruding from the mouth of the mouthpiece, so that even if an external force is applied near the tip, only the cone-shaped member is deformed. The base does not deform. In addition, since a substantially conical coil spring is wound around the peripheral surface of the cone-shaped member, when the external force is removed from the cone-shaped member that has been deformed by the external force, the elastic force of the coil spring restores the shape of the cone-shaped member. It will be original.

[0007]

【Example】

 As shown in FIG. 1, a nozzle 6 according to an embodiment of the present invention comprises a cone-shaped mouthpiece 1 and a plastic which is fitted onto the tip of the mouthpiece 1 with its tip protruding from the mouth 1a of the mouthpiece 1. The cone-shaped member 2 and the coil spring 3 having a substantially conical shape wound around the peripheral surface of the cone-shaped member 2.

The base 1 has a cone shape with a narrowed tip, and the rear end is fixed to the gun body 5 by a nut 4. The gun body 5 is filled with caulking material (not shown) inside, and the caulking material is discharged from the mouth portion 1a of the die 1 by pressurizing the caulking material from the outside. The cone-shaped member 2 is a cone-shaped member made of vinyl chloride resin or the like. The tip of the cone-shaped member 2 projects about 10 mm from the mouth portion 1a of the mouthpiece 1.

According to the nozzle 6 configured as described above, even if an external force is applied to the vicinity of the tip, only the cone-shaped member 2 is deformed and the mouthpiece 1 is not deformed, and the nozzle 6 is wound around the peripheral surface of the cone-shaped member 2. Due to the elastic force of the coil spring 3, even if the cone-shaped member 2 is once deformed by an external force, the shape of the cone-shaped member 2 is restored when the external force is removed. Therefore, as shown in FIG. 2, when the caulking material is applied to the notch portion 8a of the joist 8 conveyed by the conveyor (not shown) using the nozzle 6, the dimensional error of the joist 8 or the position of the joist 8 is displaced. Even if the nozzle 6 comes into contact with the joist 8 due to, for example, the nozzle 6 does not bend and become unusable.

[0010]

[Effect of device]

 In the nozzle of this invention, the plastic cone-shaped member is externally fitted to the tip of the mouthpiece with the tip protruding from the mouth of the mouthpiece. Since the base does not deform and the cone-shaped coil spring is wound around the peripheral surface of the cone-shaped member, once the external force is removed from the cone-shaped member that has been deformed by the external force, the elasticity of the coil spring will change. The force restores the shape of the cone-shaped member. Therefore, when the caulking material or the like is applied to the joists conveyed by a conveyor or the like, even if the caulks or the like come into contact with the joists, the joists do not bend and become unusable.
