[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] A simple lock made from production waste, such as Figure 1-2As shown, it includes a latch hole seat 1, a round steel latch shaft 2, a latch box 3, and a rotating nut 4. The latch hole seat 1 is placed in front of the latch box and is set separately. The round steel latch shaft 2 is inserted into the latch hole seat 1, passes through the rotating nut 4, and extends to the rear of the latch box 3. The round steel latch shaft 2 is drilled and buried with a metal short rod 21 welded. A sliding groove 5 is opened on the upper rear of the latch box. A nut handle 6 is arranged on the round steel latch shaft 2 in the sliding groove 5. When the nut handle 6 is rotated, the round steel latch shaft 2 slides forward and backward. The latch hole seat 1 is provided with a latch hole 10 and a fixing hole 11 of the latch hole seat. The latch hole seat 1 is aligned with the central horizontal line of the round steel latch shaft 2. The hole diameter of the latch hole 10 matches the shaft diameter of the round steel latch shaft 2, and they are locked by plugging together.

[0035] like Figure 3 As shown, the latch cabin box 3 is a semi-open box body, based on industrial square steel, and is manufactured by cutting and grooving. It is divided into a front cabin area 31, a middle cabin area 32 and a rear cabin area 33. A metal perforated plate 34 is provided between each cabin area. The metal perforated plate is fixed by a fixing hole 35 provided at the bottom of the latch cabin box 3. The front cabin area 31 is a guide area for the round steel latch shaft 2. A rotatable nut 4 is provided in the middle cabin area 32. The nut handle 6 on the round steel latch shaft 2 is provided in the rear cabin area 33.

[0036] The metal hole plate 34 is made of the same thin plate as the bolt cabin box 3. An axial hole is opened in the center of the hole plate, and the hole size matches the round steel bolt shaft 2. The metal hole plate 34 matches the front and rear openings of each cabin of the cabin box and is welded and fixed.

[0037] like Figure 4 As shown, the round steel bolt shaft 2 is made of a metal round bar and placed in the bolt compartment box 12. The entire round steel bolt shaft 2 passes through the rotating nut 4, and the metal hole plate 34 matches the bolt hole 10 and is inserted and locked. The number of metal short bars 21 and round steel bolt shafts 2 is determined according to the preset number of rotating nuts 4.

[0038] like Figure 5-7 As shown, the rotating nut 4 is placed in the middle cabin area 32 of the latch cabin box and adopts a hexagonal internal thread nut. To avoid electrochemical corrosion, the material of the rotating nut 4 is consistent with the latch cabin box 3 and the round steel latch shaft 2; the inner diameter of the rotating nut 5 matches the diameter of the round steel latch shaft 2.

[0039] The six surfaces of the rotating nut 5 are printed with coded codes "1-6" one by one, and a circumferential rotating groove 5-2 is arranged inside along the circumferential direction of the nut, and an axial groove 5-1 is opened on the inner circle of the code surface corresponding to the rotating nut 5 according to the set secret code.

[0040] The sizes of the circumferentially rotating slide groove 5-2 and the axial slide groove 5-1 match the sizes of the metal short rods 13 embedded in the shaft of the middle cabin area 12-2 section.

[0041] To use this simple lock made from production waste, you can take the following steps:

[0042] S1, the six surfaces of the rotating nut 4 are printed with secret codes "1-6" one by one, and the rotating groove 42 along the circumferential direction of the internal nut is opened according to the secret code, and the axial groove 41 is opened on the inner circle of the code surface corresponding to the rotating nut 4;

[0043] S2, turn the rotating nut 4, the metal short rod 21 on the round steel bolt shaft 2 limits the axial movement of the rotating nut 4 in the rotating slide groove 42, and performs a circular rotation. When all the rotating nuts 4 in the middle cabin area 32 are rotated to the corresponding preset coded codeword, they are aligned with the center line of the sliding groove 5. At this time, the axial slide groove 41 in the rotating nut 4 is aligned with the metal short rod 21, and the rotating nut 4 is opened;

[0044] S3, the nut handle 6 is moved to move the round steel pin shaft 2 and align it with the pin hole 10, and then the nut 4 is rotated in a displaced manner, so that the axial grooves 41 in all nuts are no longer aligned with the metal short rod 21, that is, the pin shaft is locked;

[0045] S4, when unlocking the simple lock, turn all the rotating nuts 4 to the corresponding preset password numbers and align them with the center line of the sliding groove 5, align the axial sliding groove 41 in the rotating nut 4 with the metal short rod 21, and move the nut handle 6 to move the round steel bolt shaft 2 in the opposite direction of the insertion. At this time, the simple lock can be opened.

[0046] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
