Abstract

The utility model relates to an electric water heater, which comprises an outer shell, an inner container that is arranged inside the outer shell, a first bolt that connects the outer shell and the inner container, a hook that is fixed on the outer shell through the first bolt and a hook pad that is used for the insulation and is arranged between the outer shell and the inner container; the utility model is characterized in that the hook pad is projected shape, the thickness of the projected part more than or equal to that of the outer shell plus that of the hook, the projected part passes through the outer shell and the hook, an axial hole that is used for passing the first bolt is arranged at the center of the hook pad, and an insulated bolt pad is arranged between the hook and the first bolt. The utility model has the advantages of simple structure, effective insulation between the outer shell and the inner container, good insulation effect, safe and reliable utilization, convenient installation, etc.

Description

A kind of electric heater

Technical field

The utility model relates to a kind of electric heater.

Background technology

Existing electric heater, it comprises shell, is located at the inner bag in the shell, connect first bolt that shell and inner bag are used, by first hook that is bolted on the shell, be located at the hook cushion block that plays buffer action between shell and the inner bag, be enclosed within the insulated ring on first bolt.Because this hook cushion block is a slab construction, insulated ring is used for isolating first bolt and shell, and its installation is cumbersome, and after using a period of time, insulated ring also can wear out, and can not use dangerous effectively with shell and inner bag insulation.Also have a kind of electric heater in addition, on inner bag, be provided with a support, on shell, also be provided with a support, between two stands, be provided with a felt pad, by bolt they are fixed again, its complex structure, insulation effect is also undesirable.

The utility model content

The utility model is to overcome the deficiencies in the prior art and provide a kind of simple in structure, and insulation effect is good, a kind of electric heater safe in utilization, reliable.

In order to achieve the above object, the utility model is to realize like this, it is a kind of electric heater, comprise shell, be located at the inner bag in the shell, connect first bolt that shell and inner bag are used, be bolted to hook on the shell by first and be located at the hook cushion block that plays insulating effect between shell and the inner bag; Be characterised in that: the hook cushion block is convex shape, the thickness of its projection adds the thickness of hook more than or equal to shell, and the part of protruding is passed shell and hook, center at the hook cushion block has the axial hole that first bolt can pass, and also is provided with the bolt cushion block of insulation between the hook and first bolt.

Also comprise second bolt that connection shell and inner bag are used, by second passive glue pin and the glue foot pad piece that is bolted on the shell; Glue foot pad piece is convex shape, and the thickness of its projection is more than or equal to the thickness of shell and pass shell, and the part of its protrusion also matches with the glue foot bottom, has the axial hole that second bolt can pass at the center of glue foot pad piece.

Between described first bolt and bolt cushion block, be provided with a plain washer.

The utility model advantage compared with prior art is, and is simple in structure, can be effectively with shell and inner bag insulation, and insulation effect is good, and is safe in utilization, reliable, easy for installation.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged drawing of the local A of Fig. 1;

Fig. 3 is the enlarged drawing of the local B of Fig. 1.

Specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

As shown in Figures 1 to 3, it is a kind of electric heater, it comprises shell 1, be located at the inner bag 2 in the shell, connect first bolt 5 that shell and inner bag are used, by first hook 5 that is bolted on the shell, be located at the hook cushion block 3 that plays insulating effect between shell and the inner bag, be located at the bolt cushion block 4 that plays insulating effect between the hook and first bolt, connect second bolt 10 that shell and inner bag are used, by the second glue pin 9 that is bolted on the shell, be located at glue foot pad piece 8 and be located at first bolt and the bolt cushion block between plain washer 6.In the present embodiment, hook cushion block 3 is convex shape, the thickness of its projection adds the thickness of hook 7 more than or equal to shell 1, and the part of protruding is passed shell and hook, shell and inner bag are isolated, thereby make the insulation of shell and hook and inner bag, have the axial hole that first bolt 5 can pass at the center of hook cushion block.Glue foot pad piece also is convex shape, the thickness of its projection is more than or equal to the thickness of shell and pass shell, the part of its protrusion also matches with the glue foot bottom, shell and inner bag are isolated, make the insulation of shell and inner bag, have the axial hole that second bolt 10 can pass at the center of glue foot pad piece.

Claims
