Description

Technical Field

[0001] The utility model relates to the technical field of electric heating blankets, in particular to an electric heating blanket with a heat preservation function. Background Art

[0002] An electric blanket, also known as an electric mattress, is a contact electric heating appliance. It weaves or sews specially made, standard-insulated soft-cord electric heating elements into the blanket in a snake-like shape. It emits heat when powered on. It is mainly used to increase the temperature in the bed while people sleep to achieve the purpose of heating. It can also be used to dehumidify bedding. It consumes little power, has adjustable temperature, is easy to use, and is widely used.

[0003] According to a disclosed electric blanket with leakage protection function (Announcement No.: CN109246868A), the heating wire and plug in the above application are in a scattered state when in use or not in use. When not in use, the heating wire and plug are scattered and easily pulled, stepped on or squeezed by external forces, causing the internal wire of the heating wire to break or the metal pins of the plug to deform, thereby affecting the use and heat preservation effect of the electric blanket. To address this problem, we have proposed an electric heating blanket with heat preservation function. Utility Model Content

A moving block is fixedly installed on the surface of the vertical plate, and the moving block passes through the support block and is slidably connected to the support block. A cross bar is fixedly installed on the inner wall of the support block, and the cross bar passes through the moving block and is slidably connected to the moving block to avoid damage to the internal heat conductor due to pulling, stepping on or squeezing by external force, thereby ensuring the insulation effect of subsequent use.

[0006] Preferably, the cross-sectional shape of the limiting hole is L-shaped, and the L-shaped limiting hole can limit the movement of the support rod.

[0007] Preferably, the control component also includes a fixing part, which includes: spring 1, one end of which is fixedly mounted on the surface of the cross bar, and the other end of which is fixedly mounted on the surface of the moving block. When the moving block loses its restriction, it can bounce up under the support of spring 1.

[0008] Preferably, a flat rod is fixedly mounted on the surface of the moving block, the flat rod passes through the slider and is slidably connected to the slider, and a support rod is fixedly mounted on the surface of the slider, so that the slider can slide stably on the surface of the flat rod.

[0009] Preferably, a support block is fixedly installed on the surface of the support rod, the support block passes through the support block and is slidably connected to the support block, and a fixed block is fixedly installed on the surface of the support block. When the fixed block moves, the support block can drive the support rod to move laterally in the support block.

[0010] Preferably, a through hole is provided on the surface of the support rod, and the provision of the through hole can limit the rebound of the support rod.

[0012] Compared with the prior art, the present invention provides an electric heating blanket with heat preservation function, which has the following beneficial effects:

[0013] 1. The electric heating blanket with heat preservation function is provided with a control component. The drum winds the plug wire and inserts it into the groove inside the drum. The fixed block is moved on the surface of the support block. The support block fixed on the surface of the fixed block drives the support rod to move laterally in the support block. When the support rod moves, the slider fixed on the surface of the support rod slides against the moving block through the flat rod. When the moving block moves on the surface of the cross bar, the vertical plate fixed on the surface of the moving block drives the protective plate to move laterally synchronously. The moved protective plate is inserted into the groove provided on the surface of the drum to fix the plug wire, avoid the loosening of the plug wire after winding, and avoid damage to the internal heat conductor due to pulling, stepping on or squeezing by external force, so as to ensure the heat preservation effect of subsequent use.

[0014] 2. The electric heating blanket with heat preservation function is provided with fixing parts. Since there are multiple groups of through holes on the surface of the support rod, when the push rod is not subjected to the squeezing force, the clamping rod will be stuck in the two groups of through holes, and the support rod cannot be moved. This method can perform secondary fixation on the plug-in wire after winding, avoiding the loosening of the protective plate due to accidental touch. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The cross-section of the limiting hole 12 is L-shaped, and the L-shaped limiting hole 12 can limit the movement of the support rod 954. The control assembly 9 also includes a fixing member 95, which includes a spring 1 951. One end of the spring 1 951 is fixedly mounted on the surface of the crossbar 94, and the other end of the spring 1 951 is fixedly mounted on the surface of the moving block 93. When the moving block 93 loses its limit, it can bounce up under the support of the spring 1 951. A flat rod 952 is fixedly mounted on the surface of the moving block 93. The flat rod 952 passes through the slider 953 and is slidably connected to the slider 953. The support rod 954 is fixedly mounted on the surface of the slider 953, and the slider 953 can slide stably on the surface of the flat rod 952. A support block 955 is fixedly mounted on the surface of support rod 954. Support block 955 extends through support block 11 and is slidably connected thereto. A fixing block 956 is fixedly mounted on the surface of support block 955. When fixing block 956 moves, support block 955 drives support rod 954 to move laterally within support block 11. A through hole 957 is formed on the surface of support rod 954 to limit the rebound of support rod 954. A round rod 9510 is fixedly installed on the inner wall of the support block 11. The round rod 9510 passes through the push rod 959 and is slidably connected to the push rod 959. A clamping rod 958 is fixedly installed on the surface of the push rod 959.

After use, the plug wire 7 is wound on the surface of the drum 8, and the cable at the end of the plug wire 7 is inserted into the groove 10. After being inserted, the push rod 959 is pushed on the surface of the support block 11. The push rod 959 is supported by the spring 9511. The push rod 959 moves laterally on the surface of the round rod 9510. When the push rod 959 moves, the card rod 958 fixed on the surface of the push rod 959 can be removed from the through hole 957. After moving out, the pushing force is maintained to move the fixed block 956 on the surface of the support block 11. When the fixed block 956 moves, the support block 955 fixed on the surface of the fixed block 956 drives the support rod 954 to move. When the support rod 954 moves, the slider 953 fixed on the surface of the support rod 954 contacts the moving block 93 on the cross bar through the flat rod 952. The surface of 94 slides, and the vertical plate 92 fixed on the surface of the moving block 93 drives the protective plate 91 to move horizontally synchronously. The moved protective plate 91 is stuck in the groove 10 opened on the surface of the roller 8 to fix the plug wire 7. After fixing, the fixed block 956 is moved on the surface of the support block 11. The fixed block 956 moves to the corner of the L-shaped limit hole 12 to complete the fixation of the protective plate 91. After fixing, release the force of pushing the push rod 959, and the card rod 958 loses its limit and is stuck in the through hole 957 , completing the fixation of the support rod 954 and the protective plate 91, avoiding the loosening of the plug wire 7 after being wound, and avoiding damage to the internal heat conductor due to pulling, stepping on or squeezing by external force, thereby ensuring the insulation effect of subsequent use. When it is necessary to release the fixation of the plug wire 7, the fixed block 956 is moved out from the corner of the limiting hole 12, and the movable block 93 can lose the restriction and bounce up under the support of spring 1 951, and the protective plate 91 is moved out of the groove 10 in the drum 8, releasing the fixation of the plug wire 7.
