Abstract
The present invention discloses a new container window device and a manufacture method thereof. The new container window device comprises a container provided with a hole with folded edges, a transparent member arranged the container hole, a sealing ring arranged between the container and the transparent member, and a metal frame, wherein the section of the metal frame of the present invention forms an L shape; the folded edges of the container hole tightly press one edge of the metal frame; the other edge of the metal frame tightly presses the transparent member. The transparent member is fixedly connected to the container only by inward bending and folding the edges of the container hole to tightly press the metal frame and downwards press the other edge of the metal frame so as to tightly press the transparent member. The present invention has the advantages of simple structure manufacture method, low cost, firmness, reliability and high practicability.
Description
Affiliated technical field
The present invention relates to a kind of apparent window device on container and preparation method thereof, viewing device of especially a kind of electric heating pipkin and preparation method thereof.
Background technology
The method for making of existing apparent window on container has ultrasonic welding, injection moulding, glue bonding, and screw, back-off captive joint, and said method complex structure, cost height connect as ultrasonic welding, screw; Perhaps because metal is different with the thermal expansion coefficient of plastic, transparent part, heating repeatedly and cause connecting insecure, bonding as injection moulding, glue; Perhaps manufacture craft is difficult to realize, connects as back-off.
Summary of the invention
The object of the present invention is to provide a kind of structure and make simple, apparent window device on container of being connected firmly and preparation method thereof.
In order to achieve the above object, the inventive system comprises a perforate flanging container, be installed in Transparent Parts on the container hole, be arranged on a seal ring and a metal frame between container and the Transparent Parts simultaneously; Metal frame of the present invention is the ring frame that adapts with container hole, and its cross section is L-shaped, and the flanging of container hole compresses one side of metal frame " L ", and the another side of metal frame " L " is profile of tooth and compresses Transparent Parts.
Method of the present invention is: the edge of perforated container is bent inwards compresses one side of metal frame " L ", and metal frame is fixed on the wall of container, and leak-tight joint; Again Transparent Parts is inserted in the perforated container position, and between the flanging of container hole and Transparent Parts, places a seal ring; Make the another side of metal frame " L " compress Transparent Parts.
Flanging is connected with container with Transparent Parts respectively on the both sides of metal frame of the present invention, thereby makes leak-tight joint between Transparent Parts and the container, and structure and method for making are very simple, and cost is low, and solid and reliable, and is practical.
Describe embodiments of the present invention in detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a front elevation of the present invention;
Fig. 2 is the cutaway view of A-A direction among Fig. 1;
Fig. 3 is local inside view of the present invention.
The specific embodiment
As shown in Fig. 1 and Fig. 2, device of the present invention has the Transparent Parts 1 of L-shaped metal frame 4, seal ring 3 and outer shroud groove of a container 2, cross section.Perforate on container 2 sidewalls, the perforate flange that bends inwards, and compress one side of metal frame 4 " L ", make captive joint between the two.Transparent Parts 1 is enclosed within the perforate position of container 2, and the flanging of container 2 is placed in the groove of Transparent Parts 1, and simultaneously, a seal ring 3 is also placed in this position, makes internal tank form sealing; The outer of Transparent Parts 1 groove contacts with metal frame 4, and is compressed by the another side of metal frame 4 " L ".Because container 2 compresses metal frame 4, metal frame 4 compresses Transparent Parts 1, thereby makes firm being connected of formation between container 2 and the Transparent Parts 1.
Method for making of the present invention is: 1. according to the pre-container made of required size, strut member and Transparent Parts; 2. after perforate on the wall of container, with the bending position that metal frame is inserted in container, flanging then makes it to compress metal frame; 3. installation Transparent Parts is placed in the groove of Transparent Parts the container flanging, places seal ring in this position simultaneously; 4. press down the serrated edge of metal frame, make it to be pressed on the outer of Transparent Parts groove, get final product leak-tight joint between metal frame and the Transparent Parts.
Claims (3)
