Description

Cato structure for nozzles and protective sleeves

The invention relates to the technical field of protection of nozzles and protective sleeves, in particular to a card tray structure for nozzles and protective sleeves.

In the high-temperature heating device, a heating gun body that extends from the top is commonly used, and the heating gun body needs to be inserted into the high-temperature inner cavity from the top of the heating device. The heating gun body is mostly made of metal materials. In order to be used for a long time under high temperature conditions without damage, the common method is to cool the heating gun body with water. Although water cooling protects the equipment, it will cause heat loss in the high temperature inner cavity. At the same time, although the heating gun body has cooling protection, the outer surface may still not be used for a long time due to local damage caused by high temperature, so it is necessary to use a high temperature resistant protective cover on the outside of the heating gun body. The general protective sleeve is fixed with a wire port, but the ceramic protective sleeve is in a high temperature environment, and the heating gun body is protected by water cooling. When the metal ring card holder structure fixed on the outside of the heating gun is adopted, the fixing structure is mostly connected with the heating device by a wire port, which will cause damage to the metal ring due to poor heat conduction, which will ultimately affect the use of the protective sleeve.

The purpose of the present invention is to provide a nozzle and protective sleeve card tray structure, which solves the problem that the fixed structure outside the heating gun is damaged and affects the use of the protective sleeve in the prior art, and can provide better protection for the heating gun and the nozzle.

In order to achieve the above purpose, this creation adopts the following technical solutions:

A nozzle structure and a protective cover, comprising a heating gun and a nozzle, the lower end of the heating gun is connected with the nozzle, the outer side of the heating gun and the nozzle is provided with a protective cover, and the outer side of the nozzle is provided with an integrated outer A convex card tray, the protective sleeve cooperates with the outer convex tray to form a tray structure, and there is a gap between the protection sleeve and the tray structure and between the heating gun and the nozzle.

Optionally, the protective sleeve is a straight tube without a bayonet or a straight tube with a concave bayonet.

Optionally, the material of the protective cover is ceramic material or graphite material.

Optionally, the protective cover is a straight tube without a bayonet, and the convex tray provided on the outer side of the nozzle is supported below the straight tube without a bayonet to form a tray structure for holding the protective sheath.

Optionally, the protective cover is a straight tube with an inner concave bayonet, and the outer convex catch on the outer side of the nozzle is supported in the concave bayonet of the protective cover to form a catch structure for holding the protective cover.

Optionally, the shape of the outer convex card holder is a ring, or a portion that is reserved after cutting the ring.

Optionally, a thermal insulation material is provided between the outer side of the heating gun and the protective cover, and the thermal insulation material is a refractory felt or a porous high temperature resistant ceramic material.

Compared with the prior art, the present invention has the following beneficial effects:

In this creation, an integrated card tray structure is arranged on the nozzle, so that the protective cover can better protect the main body of the structure, and a gap needs to be reserved between the protective cover and the card tray structure and the heating gun to be protected and the nozzle to avoid high temperature conditions. , the dimensional change of each component due to thermal expansion affects the stability of the structure.

The present creation will be further described below in conjunction with accompanying drawings 1 and 2.

As shown in Figs. 1 and 2, the nozzle and the protective cover of the card tray structure include a heating gun 2 and a nozzle 1. The lower end of the heating gun 2 is connected to the nozzle 1, and one end of the heating gun 2 is arranged on the outside of the nozzle 1. With protective cover 3. The outer side of the nozzle 1 is provided with an integrated outer convex tray 4 , and the protective cover 3 cooperates with the outer convex tray 4 to form a tray structure. There is a gap between the protective sleeve 3 and the card tray structure 4 and the gun body of the heating gun 2 to be protected and the nozzle 1 to avoid the dimensional changes of the components due to thermal expansion under high temperature conditions, which will affect the stability of the structure. A heat insulating material 6 is disposed between the outside of the gun body of the heating gun 2 and the protective cover 3 , and the heat insulating material 6 includes a refractory felt or a porous high temperature resistant ceramic material.

The protective cover 3 is made of ceramic material or graphite material. The protective cover 3 can be a straight tube without a bayonet, or a straight tube with a concave bayonet. When the protective cover 3 is a straight tube without bayonet, the convex tray 4 provided on the outer side of the nozzle 1 is supported under the straight tube without bayonet to form a tray structure for supporting the protective cover 3 . When the protective cover 3 is a straight tube with a concave bayonet, the outer convex catch 4 on the outside of the nozzle 1 is supported in the concave bayonet 5 of the protective cover 3 to form a catch structure for holding the protective cover 3 .

As shown in FIG. 2 , the shape of the convex tray 4 is a circular ring, or the part remaining after cutting the circular ring, so as to not only play the role of a tray, but also reduce the heating surface. The cutting shape can be arbitrarily cut without affecting the structure of the nozzle 1 and the support of the tray 4 .
