[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lock structure for a leisure heat insulation box.

[0002]

[Prior art]

 The structure of the lock unit of the conventional thermal insulation box is divided into a lock between the cover 1 and the cover main body 2 and a lock structure between the cover main body 2 and the box 3. As shown in FIG. 1, the lock structure between the cover 1 and the cover main body 2 is mainly provided with a slot 21 in the cover main body 2. Locking rods 22 are installed on both sides of the slot 21. A hook edge 11 is provided at a position corresponding to the locking rod 22 of the cover 1. An operating plate 12 and a spring 13 are arranged on both sides thereof. Pushing the operation plate 12 to move and loosen the position of the operation plate 12 has an effect of opening the cover 1.

As shown in FIGS. 2 and 3, the lock structure between the cover main body 2 and the box 3 mainly has an active plate 23 pivotally provided on a side portion of the cover main body 2. A positioning rod 24 and a position limiting rod 25 made of a metal material are pivotally mounted on upper and lower portions inside the active plate 23. A fixing hook 31 is provided outside the box 3 at a position corresponding to the positioning rod 24. By rotating the active plate 23 after the positioning rod 24 has been inserted therein, the position limiting rod 25 is locked to the bottom edge of the fixed hook 31 to achieve the locking effect.

[0004]

[Problems to be solved by the invention]

 However, the above-mentioned conventional structure has the following disadvantages. The installation of the operating plate 12 and the spring 13 has poor stability and tends to loosen, so that the operation of the operating plate 12 is not perfect and moves. As a result, the opening and closing operation is not reliable. Further, since the two operating plates 12 are acted on by one spring 13, a phenomenon occurs in which the force is applied but not uniform during use. Frequently, the disadvantage that one side cannot be opened is likely to occur. Manufacturing and assembling of the active plate 23, the positioning rod 24, and the position limiting rod 25 in the cover main body 2 cannot be performed unless they are respectively processed, so that assembly and molding cannot be performed. Further, since the pivoting method is adopted for the position limiting rod 25 after assembly, the positioning and coupling of the position limiting rod 25 become loose after a long use. As a result, when it is relatively actuated and locked on the bottom edge of the fixed hook 31, the ideal locking and tightness of the lock cannot be obtained, and at the same time, the pivotal position limiting rod 25 is also required. The required strength cannot be achieved. Accordingly, an object of the present invention is to provide a lock structure for a leisure heat insulation box which can reliably open and close, achieve an ideal degree of locking and tightness of lock, and reduce costs.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the lock structure of the leisure heat storage box according to the present invention pushes the support rod of the operating plate of the cover through the through hole of the stop block and pushes the lock plate. When combined with the recovery force of the installed spring, not only is the force applied evenly during operation, but it also has the effect of opening and closing reliably.

The lock structure of the leisure heat insulation box of the present invention includes a lock between the cover and the cover main body and a lock structure between the cover main body and the box. Pass the operating plate support rod of the cover through the through hole of the stop block, and install it so that the locking plate is pushed. When the operating plate of the cover is moved, the operating plate support rod retreats the stop block. Further, the cover is locked or released by utilizing the recovery force of the spring, and is separated from the cover.

[0007] The cover is shaped to lock corresponding to the box. Mainly on each of the two symmetrical sides of the cover, an active board is pivoted. A positioning rod is set inside the activity plate. Below the positioning rod, a position limiting block is formed from an active plate. On the two symmetrical outer sides of the box, fixed clip slices are set which are locked corresponding to the positioning rods inside the active plate. By placing the positioning rods of the cover's active plate into the hooks of the fixed clip flakes of the box, the active plate can be actuated to rotate or swing. When the position limit block is rotated or swung to the bottom edge of the hook, the position limit block is pushed by the active plate and the position limit block, restricted, and locked. Therefore, an insulated box with excellent lock and close effect is formed.
