Abstract
Watercolor pencil field is the utility model is related to, especially a kind of to prevent that fire-retardant watercolor pencil, including pen body and the cap for brush, the pen body include inner cylinder and outer barrel, the inner cylinder is located in outer barrel, and one end closing of inner cylinder, the other end are provided with nib；The outer barrel and the cap for brush are metal cylinder, and the outer surface of outer barrel and the cap for brush is coated with outer thermal insulation layer, and inner surface is provided with inner insulating layer.Outer barrel and the cap for brush are using metal material, will not burn, will not increase firepower when surrounding is caught fire, and outer thermal insulation layer is set in the outer surface of outer barrel and the cap for brush, and inner surface sets inner insulating layer, and the high temperature for avoiding the external world is transferred to inner cylinder and causes inner cylinder to damage.
Description
Technical field
Watercolor pencil field is the utility model is related to, it is especially a kind of to prevent fire-retardant watercolor pencil.
Background technology
Watercolor pencil is the common draw tool of children, and existing watercolor pencil includes pen body and the cap for brush, and pen body and the cap for brush are adopted
With plastic material, easily burning, can catch fire quickly when running into flare, strengthen firepower, may ignite more articles, cause
Serious fire.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-fire-retardant watercolor pencil, itself will not burn, avoid
Fire is spread.
Technical solution is used by the utility model solves its technical problem：One kind prevents fire-retardant watercolor pencil, including pen body
And the cap for brush, the pen body include inner cylinder and outer barrel, the inner cylinder is located in outer barrel, and one end closing of inner cylinder,
The other end is provided with nib；The outer barrel and the cap for brush are metal cylinder, and the outer surface of outer barrel and the cap for brush be coated with it is outer every
Thermosphere, inner surface are provided with inner insulating layer.
Further, the outer thermal insulation layer and inner insulating layer are ceramic fiber layer.
Further, the end face of the outer barrel is provided with the groove of circular ring shape, and the groove inner wall is provided with rubber ring
The end face of the cap for brush is provided with the boss of circular ring shape, and the boss stretches into groove and is interference fitted with rubber ring.
Further, the inner cylinder outer wall and outer barrel bonding connection.
The beneficial effects of the utility model are：Outer barrel and the cap for brush are using metal material, will not be burnt, when surrounding is caught fire
Shi Buhui increases firepower, and outer thermal insulation layer is set in the outer surface of outer barrel and the cap for brush, and inner surface sets inner insulating layer, avoids outer
The high temperature on boundary is transferred to inner cylinder and causes inner cylinder to damage.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, one kind of the utility model prevents fire-retardant watercolor pencil, including pen body and the cap for brush 2, the pen body includes interior
Cylinder 3 and outer barrel 1, the inner cylinder 3 are located in outer barrel 1, and one end closing of inner cylinder 3, the other end are provided with nib
4；The outer barrel 1 and the cap for brush 2 are metal cylinder, and the outer surface of outer barrel 1 and the cap for brush 2 is coated with outer thermal insulation layer 5, inner surface
It is provided with inner insulating layer 6.
Inner cylinder 3 uses plastic material, for storing ink.Outer barrel 1 and the cap for brush 2 can use stainless steel, copper etc., preferably
It is light-weight using aluminium alloy.Outer thermal insulation layer 5 and inner insulating layer 6 can use glass fibre, high silica fiber, mullite fiber, profound
The existing common heat-barrier material such as military rock fiber, it is preferred that the outer thermal insulation layer 5 and inner insulating layer 6 are ceramic fiber layer.Pottery
Porcelain fiber is with light-weight, high temperature resistant, thermal capacitance is small, it is functional, non-toxic etc. excellent to keep the temperature excellent heat insulating performance, high-temperature heat insulation
Point.Outer barrel 1 and the cap for brush 2 are using metal material, will not burn, will not increase firepower when surrounding is caught fire, in 1 He of outer barrel
The outer surface of the cap for brush 2 sets outer thermal insulation layer 5, and inner surface sets inner insulating layer 6, avoid extraneous high temperature be transferred to inner cylinder and
Inner cylinder is caused to damage.
In order to ensure the thermal insulation of watercolor pencil entirety, while the cap for brush 2 is convenient for disassembly and assembly, and the end face of the outer barrel 1 is set
There is a groove of circular ring shape, the end face that the groove inner wall is provided with the cap for brush 2 described in rubber ring 8 is provided with the boss 7 of circular ring shape, institute
Boss 7 is stated to stretch into groove and be interference fitted with rubber ring 8.
Preferably, 3 outer wall of inner cylinder and 1 bonding connection of outer barrel.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
