Description

The electric heating platen

The utility model relates to the glass platen that usefulness is write in a kind of office, particularly a kind of electric heating platen that winter, office can be heated when writing.

Electric heating platen commonly used is a base plate with plank or plastic plate mostly on people's desk or the desk now, and the platen tetra-pack is with four cornerites, and power line is then directly drawn between glass plate and base plate.The shortcoming of this electric heating platen is that poor flatness, mechanical strength are low.China Patent No. 95246782.8 discloses a kind of electric heating platen escutcheon, comprise moulding and cornerite, the two ends of moulding become 45 degree oblique angles respectively, and moulding one side has groove, four mouldings are flush-mounted in respectively around the platen, and four jiaos are equipped with cornerite and are connected and fixed moulding and become the platen escutcheon.Compare with electric heating platen in the past, though improved the evenness and the mechanical strength of platen, four mouldings are still fixed by cornerite, install to fix insecurely between loaded down with trivial details, the moulding, cause that easily hook bumps disadvantages such as clothes.

For overcoming the problem of above-mentioned existence, the purpose of this utility model just provide a kind of simple in structure, be connected firmly, evenness is good, mechanical strength is high, product is elegant in appearance a kind of electric heating platen.

For achieving the above object, a kind of electric heating platen of the present utility model, comprise four frame bars, be arranged on base plate, electrothermal layer, platen glass in the moulding, described moulding cross section inboard is microscler square groove, the outside is a groove, the moulding two ends are 45 degree oblique angles, connect by linking in the barb iron angle between the moulding, are complementary in the microscler square groove of button insertion moulding and with microscler square groove in the barb iron angle.

Button is provided with at least two above barb iron angles in the described barb iron angle, and discount portion width is less than the width of barb iron angle the widest part in the barb iron angle.

Described moulding upper outside is provided with curved flanges, and the inboard is a step, and platen glass is placed on the step, and the curved flanges height is consistent with the thickness of platen glass.

Described moulding side is provided with built-in socket.

Described moulding material is plastic material or aluminum alloy materials.

The utility model is because moulding cross section inboard is microscler square groove, the outside is a groove, the moulding two ends are 45 degree oblique angles, connect by linking in the barb iron angle between the moulding, button is provided with at least two above barb iron angles in the barb iron angle, is complementary in the microscler square groove of button insertion moulding and with microscler square groove in the barb iron angle; Reduced by four limit cornerites, make simultaneously between the moulding connect more firm, again because moulding is provided with curved flanges and step, make that the utility model evenness is better, overall appearance is more smooth, have characteristics such as simple in structure, easy for installation, long service life, cost are low.

Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

Fig. 1 is a floor map of the present utility model.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is a button front view in the barb iron angle.

Fig. 4 is a button vertical view in the barb iron angle.

Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of electric heating platen of the present utility model, comprise four frame bars 1, be arranged on the base plate 5 in the moulding 1, electrothermal layer 4, platen glass 2, the heating wire 3 of evenly arranging in the electrothermal layer 4, moulding 1 cross section inboard is microscler square groove 7, the outside is a groove 8, moulding 1 two ends are 45 degree oblique angles, connect by button in the barb iron angle 10 between the moulding 1, button (10) is provided with 5 barb iron angles 11 in the barb iron angle, button 10 head widths are less than the width of 11 the widest part positions, barb iron angle in the barb iron angle, are complementary in the microscler square groove 7 of button 10 insertion mouldings 1 and with microscler square groove 7 in the barb iron angle; Because moulding 1 material is plastics or aluminium alloy, therefore, the utility model has not only saved four limit cornerites, and after assembling, the barb iron angle 11 in the barb iron angle on the button 10 just tightly fastens moulding 1, makes between the moulding 1 to connect never becoming loose.

In order to make evenness of the present utility model better, moulded more elegant in appearance, be provided with curved flanges 9 in moulding 1 upper outside, the inboard is a step 6, platen glass 2 is placed on the step, curved flanges 9 height are consistent with the thickness of platen glass 2, so both can avoid platen glass to damage electrothermal layer by pressure, increase the service life, can make four frame bars 1 more smooth again, lines are more smooth.Consider the continuity that platen uses, the moulding on four limits (1) side is provided with built-in socket, and heating wire directly is connected with socket.Can avoid the dilatory inconvenience that brings of power line.
