The first embodiment is as follows:

as shown in fig. 2 to 4, the car locking structure of the present embodiment includes a car 1, a side rail 2 and a fixing member 3, through fixed subassembly 3 with carriage 1 and the fixed locking of siding track 2, concretely, detachably installs siding track 2 on carriage 1, one side and the carriage 1 laminating of siding track 2, the other side of siding track 2 is equipped with first locating part 21, furthermore, fixed subassembly 3 of this embodiment includes interior clamp splice 31, outer clamp splice 32 and fastener 33, the first end of interior clamp splice 31 compresses tightly outer clamp splice 32, the second end of interior clamp splice 31 compresses tightly lateral wall 11 of carriage 1, be equipped with the face of laminating siding track 2 on the outer clamp splice 32, interior clamp splice 31 and outer clamp splice 32 pass through fastener 33 locking carriage 1 and siding track 2, be equipped with second locating part 322 on the face of outer clamp splice 32 laminating 2, first locating part 21 and the cooperation of second locating part 322 are in order to limit the activity of siding track 2.

Preferably, the first limiting member 21 of the present embodiment is a limiting groove disposed on the side rail 2, the second limiting member 322 is a limiting protrusion disposed on the outer clamping block 32, and the limiting protrusion extends into the limiting groove to limit the side rail 2, specifically, the side rail 2 of the present embodiment includes a vertical supporting surface 22, a horizontal supporting surface 23, an oblique supporting surface 24, and a transition connecting surface 25 of the horizontal supporting surface 23 and the oblique supporting surface 24, wherein the vertical supporting surface 22 is disposed on one side of the side rail 2 and is attached to the car 1, the oblique supporting surface 24 and the transition connecting surface 25 are disposed on the other side of the side rail 2, and the limiting groove of the present embodiment is disposed on the transition connecting surface 25.

Therefore, when the outer clamping block 32 is installed on the side rail 2, only the outer clamping block 32 needs to be moved towards the side rail 2 on the left side, so that the limiting protrusion extends into the limiting groove, and when the outer clamping block 32 is removed, the outer clamping block 32 can be directly taken out towards the right side, and the installation and the removal are very convenient; simultaneously because in installation and dismantlement process, outer clamp splice 32 and curb rail 2 all can not take place to warp, even long-term use repeatedly also can not influence the locking effect of outer clamp splice 32 and curb rail 2 for the carriage locking structure of this embodiment long service life, the steadiness is good.

From the above, the carriage locking structure of this embodiment sets up spacing groove and the spacing protruding cooperation that sets up on outer clamp splice 32 through set up the other side of side rail 2 for simple to operate is swift, and because outer clamp splice 32 can not take place to warp, makes the carriage locking structure steadiness of this embodiment good, and can use for a long time.

Further, in the present embodiment, the limiting groove is disposed on the transitional connection surface 25 of the lateral support surface 23 and the diagonal support surface 24, so that when the car 1 and the side rail 2 are locked, most of the locking force is borne by the lateral support surface 23, and the lateral support surface 24 of the side rail 2 is prevented from being deformed due to excessive local stress, which causes damage to the side rail 2.

Preferably, the surface of the outer clamping block 32, which is attached to the side rail 2 in this embodiment, includes both the vertical attaching surface 324 provided with the limiting protrusion and the oblique attaching surface 325 attached to the oblique supporting surface 24, so that the side rail 2 is stressed more uniformly and is not easily deformed or damaged when being locked.

Preferably, in the embodiment, the end of the lateral support surface 23 of the side rail 2, which is in contact with the outer clamping block 32, extends to the opposite direction of the fastening member 33 to form the first protruding portion 26, the end of the outer clamping block 32, which is in contact with the lateral support surface 23, extends to the opposite direction of the fastening member 33 to form the second protruding portion 323, the first protruding portion 26 is convenient to connect with other components such as a latch assembly, and the second protruding portion 323 presses the first protruding portion 26, so that the contact area between the outer clamping block 32 and the side rail 2 is further increased, and the locking effect is improved.

As shown in fig. 4, in this embodiment, a first end of the inner clamping block 31 extends towards the outer clamping block 32 to form a first pressing surface 311, and a first pressure-bearing surface 321 that cooperates and presses with the first pressing surface 311 is correspondingly disposed on the outer clamping block 32, where the first pressing surface 311 is disposed in a zigzag or frosted shape, and the first pressure-bearing surface 321 is disposed in a plane; of course, the first pressing surface 311 may be a plane, and the first pressure-receiving surface 321 may be a saw-tooth shape or a frosted shape. Further, a second pressing surface 312 is formed at a second end of the inner clamping block 31, the second pressing surface 312 presses the side wall 11 of the car 1, the second pressing surface 312 is arranged in a zigzag or frosted shape, the side wall 11 of the car 1 is arranged in a plane, and meanwhile, as shown in fig. 2, a waist-round hole 326 for allowing the fastening piece 33 to be adjusted up and down is formed in the outer clamping block 32. So, when adjusting internal clamp splice 31, only need unscrew fastener 33 a little and can adjust, convenient operation, especially when only need carry out the thin fine setting, the governing speed is fast, efficient, convenient and fast.

According to the above, the carriage locking structure provided by the embodiment has the advantages of convenience and rapidness in installation, disassembly and adjustment, good stability and long-term repeated use.

Example two:

as shown in fig. 5, the difference between the compartment locking structure of the present embodiment and the first embodiment is that the first limiting member 21 is a limiting protrusion disposed on the transitional connecting surface 25 of the side rail 2, the second limiting member 322 is a limiting groove disposed on the vertical abutting surface 324 of the outer clamping block 32, and the limiting protrusion extends into the limiting groove to limit the side rail 2, which also has the same beneficial effects as the first embodiment.
