[0002] As people's living standards improve, some equipment used in production and life (referring to locked objects, such as vehicle-mounted expansion platform equipment or chassis cabinets, etc.) will be placed on the vehicle. After arriving at the destination or when needed, the above equipment will be removed from the vehicle.
[0003] In the chassis and cabinet manufacturing industry, specific layouts are required to meet requirements. However, due to manufacturing difficulties and accessory size limitations, many cabinet suppliers often use makeshift solutions without reasonable and reliable measures, which fail to meet market requirements.
[0004] To keep the equipment secure, sheet metal is often used around the perimeter, and then matched with appropriate locks to provide a certain degree of theft resistance. While this type of securing system is simple, practical, and low-cost, it can be inconvenient to operate, such as requiring increased effort to lift the equipment beyond the area blocked by the sheet metal.

[0035] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the embodiments and drawings.
[0036] Example 1: Figure 1 As shown, the lock structure of this embodiment is commonly used in off-road equipment. It is fixed in the equipment's lock body mounting slot. Positioning brackets 1 are located at each end of the lock structure to prevent movement in the Y direction. Typically, X refers to the length of the vehicle. Here, the X / Y directions can be set based on the actual direction. In this figure, they refer to the axial direction. Positioning brackets 1 are internally provided with rotatable positioning blocks.
[0037] like Figure 2-3As shown, a locking shaft bracket 2 is mounted inside the positioning bracket 1, and a sleeve 3 is mounted inside the locking shaft bracket 2. The sleeve 3 is rotatable within the locking shaft bracket 2. The outer shape of the sleeve 3 is circular, and the inner shape of the sleeve 3 matches the shape of the locking shaft 6. The cross-section of the locking shaft 6 is not limited to triangular or rectangular shapes, but a rectangular shape is used as an example in this embodiment. The outer side of the rear positioning bracket 1 protrudes beyond the locking shaft bracket 2. This rear positioning bracket 1 provides unilateral fixation of the equipment, preventing it from sliding out from one side.
[0038] The shaft locking bracket 2 is provided with a cavity to facilitate the stress problem caused by deformation and extrusion.
[0039] A sliding groove is provided at the bottom of the lock shaft bracket 2 for installing the lock structure on a vehicle or other locations.
[0040] The center of the lock structure is the first lock body 4, which has a mounting portion formed of two lateral folded edges with mounting holes for securing the lock structure to equipment (here, equipment refers to the locked object, and the locked object and the lock structure can also be interchanged, that is, the first lock body 4 and the second lock body 5 are interchangeable). An opening is provided at the bottom of the first lock body 4. The hollow cross-section of the first lock body 4 is circular, with a diameter identical to that of the arc on the second lock body 5.
[0041] The cross section of the first lock body 4 is Ω-shaped, and a cavity is provided in a portion outside the hollow portion of the first lock body 4 to absorb stress and discharge sediment.
[0042] The middle of the second lock body 5 is provided with a through hole that matches the shape of the lock shaft 6. The second lock body 5 is provided with multiple slots outside the through hole, which reduces the weight and production cost of the second lock body 5 on the one hand and reduces the impact of sediment erosion on the other hand.
[0043] The second lock body 5 of this embodiment is shaped like a circular chamfered piece, including a pair of parallel edges and symmetrical edges in the shape of an arc. The distance between the parallel edges of the second lock body 5 is smaller than the bottom opening of the first lock body 4; the distance between the symmetrical edges of the second lock body 5 is larger than the bottom opening of the first lock body 4 (the arc in the figure is selected as the inferior arc). The second lock body 5 can be put in or taken out from the bottom opening of the first lock body 4. When the parallel edges of the second lock body 5 are aligned with the bottom opening of the first lock body 4, the lock structure is in an open state, and the second lock body 5 can be installed in or taken out from the first lock body 4; when the parallel edges of the second lock body 5 are misaligned with the bottom opening of the first lock body 4, the symmetrical edges in the shape of an arc are close to the inner wall of the first lock body 4, the lock structure is in a locked state, and the second lock body 5 cannot be taken out of the first lock body 4. The lock shaft 6 is inserted into the through hole in the middle of the sleeve and the second lock body 5.
[0044] like Figure 4-5As shown, the positioning piece on the rear end positioning bracket 1 is provided with a lock shaft stop groove matching the shape of the lock shaft 6, and the positioning piece inside the front end positioning bracket 1 is an anti-theft lock 7. The anti-theft lock 7 is provided with a protrusion matching the shape of the lock shaft 6 on the inner side along the rotation axis. The protrusion can be inserted into the sleeve. The anti-theft lock 7 is rotated by a key matching the shape of the anti-theft lock 7, which drives the lock shaft 6 to rotate to form a lock.
[0045] The first lock body 4 is set on the equipment. At this time, the equipment (the object covering the first lock body 4) passes downward in the Z direction, and the parallel edge of the second lock body 5 is in the Z direction. The first lock body 4 forms a nested relationship with the second lock body 5 through the bottom opening, and the upper symmetrical edge of the second lock body 5 in the Z direction is close to the inner wall of the first lock body 4. There are still gaps on the lower side of the first lock body 4 and the second lock body 5 in the Z direction. On the one hand, it is convenient for the discharge of mud and sand. On the other hand, the deformation of the lock body will not affect the locking function of the first lock body 4 and the second lock body 5; at this time, when the lock shaft 6 rotates, the lock shaft 6 drives the second lock body 5 to rotate. At this time, the parallel edge of the second lock body 5 rotates to the XY plane, and the first lock body 4 and the second lock body 5 are locked. The range of rotation of the locking position along the lock shaft 6 is 10-170°.
[0046] Example 2: Similar to Example 1, in this example, the installation positions of the first lock body 4 and the second lock body 5 are interchanged. 4 is provided on a fixed part such as a vehicle, and 5 is provided on a movable part such as equipment. The principles are the same.
[0047] Example 3: Same as Example 1, in this example, the first lock body 4 is set on the equipment. At this time, the equipment is pushed in horizontally in the Y direction. At this time, the lock shaft bracket 2 is removed on one side, and the anti-theft lock 7 is replaced with a movable part to support the first lock body 4 to cooperate with the second lock body 5 in the Y direction. The lock shaft 6 is inserted into the lock shaft stop groove on the positioning bracket 1. The end of the positioning bracket 1 away from the lock shaft stop groove is provided with an anti-theft lock hole, and the equipment is also provided with an anti-theft lock hole. Figure 6 As shown, when the lock structure is in the locked position, the anti-theft lock 7 can be fixed in the anti-theft lock hole on the positioning bracket 1 and the equipment to achieve the anti-theft and locking functions; when the anti-theft lock 7 is removed, the positioning bracket 1 can be rotated to drive the lock shaft 6 to rotate, and the lock structure can be in the open position, as shown in FIG. Figure 7 shown.
[0048] Example 4: Figure 8 As shown, similar to Example 1, the second lock body 5 in this embodiment is rhombus-shaped, i.e., it includes two sets of symmetrical edges along the rotation axis, and the lock shaft 6 has a triangular cross-section. The long side L of the second lock body 5, which passes through the rotation axis, connects to the inner wall of the hollow cavity of the first lock body 4; the short side L of the second lock body 5, which passes through the rotation axis, is smaller than the bottom opening of the first lock body 4.
[0049] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
