[0022] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0023] The utility model discloses a bicycle frame down tube tool box, combined with Figures 1 to 7 As shown, it includes a lower tube 1, a box body 2 and a box cover 3, the lower tube 1 is provided with a receiving slot 10, the box body 2 is embedded in the receiving slot 10 and the two are fixedly connected, the box cover 3 covers the opening of the box body 2, the inner side of the box cover 3 is formed with a hook 30 that hooks with the box body 2, a rotating shaft 31 is passed through the box cover 3, there is a preset distance between the rotating shaft 31 and the hook 30, a handle 32 is provided at one end of the rotating shaft 31 located outside the box cover 3, a locking tongue 33 is fixedly connected to one end of the rotating shaft 31 located inside the box cover 3, a locking slot 20 is provided on the side of the box body 2, the locking tongue 33 is aligned with the locking slot 20, and the locking tongue 33 is inserted into the locking slot 20 or removed from the locking slot 20 by screwing the handle 32.

[0024] In the above structure, the box body 2 is embedded and fixed in the receiving slot 10 on the top side of the lower tube 1. After placing the tool in the box body 2, the hook 30 on the inner side of the box cover 3 is hooked on one side edge of the box body 2. Then the box cover 3 covers the box body 2, and then the handle 32 is screwed until the locking tongue 33 is inserted into the locking slot 20 and the locking is completed. When the user needs to open the box cover 3, he only needs to screw the handle 32 in the opposite direction to make the locking tongue 33 come out of the locking slot 20. Compared with the method of using a tool bag in the prior art, the utility model can hide and reliably fix the tool box, and facilitate the opening and locking operations. In addition, it can prevent the tool bag from shaking and affecting riding, which can effectively improve the riding experience.

[0025] See also Figure 5 In this embodiment, an inner cover 34 is fixed to the inner side of the box cover 3, and the locking tongue 33 is arranged between the inner cover 34 and the box cover 3. The inner cover 34 can be fixedly connected to the box cover 3 by screws, and the inner cover 34 covers the lower side of the locking tongue 33, so as to hide and limit the locking tongue 33.

[0026] In order to reliably fix the rotating shaft 31 and the locking tongue 33 , in this embodiment, the rotating shaft 31 and the locking tongue 33 are fixedly connected by a pin 35 .

[0027] As a preferred method, see Figure 5 The locking slot 20 includes a wide mouth portion 200 and a narrow mouth portion 201. When the handle 32 is turned, the locking tongue 33 sequentially enters the wide mouth portion 200 and the narrow mouth portion 201. The widths of the wide mouth portion 200 and the narrow mouth portion 201 gradually decrease. When the locking tongue 33 sequentially enters the wide mouth portion 200 and the narrow mouth portion 201, the locking tongue 33 can gradually and closely match the locking slot 20, preventing the locking tongue 33 from automatically falling out under the influence of factors such as vibration, so as to ensure the reliability of locking.

[0028] On this basis, the edge of the lock tongue 33 is provided with a first lock tongue portion 330 and a second lock tongue portion 331, a limiting opening 332 is provided between the first lock tongue portion 330 and the second lock tongue portion 331, and a limiting convex buckle 202 engaged with the limiting opening 332 is formed in the locking slot 20. In the above structure, when the lock tongue 33 is locked into the locking slot 20, the limiting convex buckle 202 is engaged with the limiting opening 332, thereby playing a role of locking and limiting the lock tongue 33.

[0029] Furthermore, the second locking tongue portion 331 is inclined downward relative to the first locking tongue portion 330. The inclined second locking tongue portion 331 can be closely matched with the edge of the locking slot 20, further improving the locking reliability of the locking tongue 33.

[0030] See also Figure 4 In this embodiment, two auxiliary screws 36 are screwed on the box cover 3. The two auxiliary screws 36 can be used to install auxiliary mechanisms such as a water cup holder.

[0031] See also Figures 1 to 5 In this embodiment, the accommodating slot 10 is opened on the top side of the lower tube 1 .

[0032] In order to balance the locking stress on both sides of the locking tongue 33, in this embodiment, Figures 4 to 7 As shown, the two symmetrical edges of the locking tongue 33 are both provided with a first locking tongue portion 330 and the second locking tongue portion 331 , and the two symmetrical side portions of the box body 2 are both provided with locking slots 20 .

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
