DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0018] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "top / bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0019] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0020] The structural features of the utility model are now described in detail with reference to the accompanying drawings of the specification.
[0021] See also Figure 1-2 The utility model discloses an explosion-proof hot water bag knitting cover, comprising an open-close knitting cover 1 and an internal skeleton 4. The open-close knitting cover 1 is shaped as two half grooves connected in the middle, and a closed cavity is formed by a zipper 6, which is convenient for putting in a hot water bag 7. An array of wire holes 3 are arranged in the open-close knitting cover 1. The wire holes 3 composed of lines can be flattened when the internal skeleton 4 is inserted. The wire holes 3 of the two half grooves are symmetrical to each other. A rotating shaft 5 is arranged in the middle of the internal skeleton 4. The internal skeletons 4 on both sides of the rotating shaft 5 respectively penetrate the wire holes 3 of the two half grooves. The internal skeleton 4 is attached to the inner wall of the open-close knitting cover 1. The internal skeleton 4 is provided with a plurality of arrays in the closed cavity formed by the open-close knitting cover 1 through the wire holes 3, and a supporting effect is played by the internal skeleton 4. The internal skeleton 4 is made of elastic plastic, and the edges facing the side of the hot water bag 7 are provided with smooth chamfers to prevent scratches on the outer wall of the hot water bag 7. The open-close knitting cover 1 is provided with a thickened pad 2 corresponding to the internal skeleton 4, so that the internal skeleton 4 is more comfortable.
[0022] See also Figure 3-4The inner frame 4 is fixed with a connecting cavity 8 and an extension frame 9 at one end away from the rotating shaft 5, and a columnar bar 10 is fixed on the extension frame 9 and is stuck in the connecting cavity 8. A sliding block 11 is slidably provided in the connecting cavity 8. An upper end of the connecting cavity 8 is provided with an upper opening 14. When the opening and closing knitting sleeve 1 is closed by the zipper 6, the inner frame 4 is not subject to external force, and the columnar bar 10 presses on the sliding block 11, so that the inner frame 4 can be closed to form a protective bracket. A first spring 12 is fixed between the sliding block 11 and the bottom of the connecting cavity 8. When the built-in framework 4 is squeezed, the first spring 12 plays a buffering role, and the columnar bar 10 can slide on the sliding block 11. The width of the columnar bar 10 matches the upper opening 14. Telescopic blocks 15 are penetrated and slidably provided at both ends of the columnar bar 10. The portion of the telescopic block 15 exceeding the upper opening 14 is provided with a smooth chamfer 16. When the columnar bar 10 enters the upper opening 14, the telescopic block 15 is retracted into the columnar bar 10 under the squeezing of the chamfer 16. The telescopic block 15 prevents the columnar bar 10 from falling off in the connecting cavity 8, and the built-in framework 4 is in a closed state.
[0023] The explosion-proof hot water bag knitted cover of the utility model has a simple structure, and a pressure-bearing frame can be added to the knitted cover according to specific usage conditions. The pressure-bearing frame is easy to install, can shrink and has elasticity, can effectively protect the hot water bag, has strong practicality, and is suitable for promotion.
[0024] When using it specifically, refer to Figure 1-4 , it is possible to add a built-in skeleton 4 according to the specific use environment. For example, when sleeping and keeping warm, the open-close knitted cover 1 is opened through the zipper 6, and the built-in skeleton 4 is inserted into the wire hole 3. When the open-close knitted cover 1 is closed, the two rods of the built-in skeleton 4 rotate along the rotating shaft 5 and support each other away from the top of the rotating shaft 5 to form a protective ring. After multiple built-in skeletons 4 are installed, when the open-close knitted cover 1 is squeezed, the built-in skeleton 4 plays a supporting role. The built-in skeleton 4 is elastic plastic, and after the connecting cavity 8 is combined with the extension frame 9, when the built-in skeleton 4 is squeezed, the columnar bar 10 on the extension frame 9 presses down the sliding block 11, and the first spring 12 contracts to play a buffering role. In this way, the hot water bag 7 is protected to prevent it from being squeezed and bursting. In normal use, the built-in skeleton 4 can also be not installed to improve comfort.
[0025] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
