Description

Technical Field

[0001] The utility model relates to a device which can quickly connect a quick connector on the back of a steam box with a quick connector on a steam pipeline, in particular to a quick fastening device for a steam box on a portable square cabin vehicle and a steam pipeline. Background Art

[0002] Among the cooking square cabin vehicles in the logistics support, there are portable square cabin vehicles that are loaded with steamers. A considerable number of steamers are placed in the portable square cabins of the portable square cabin vehicles. The bottom plate of the portable square cabin is in a stepped shape with the middle low and the two sides high. Steam pipes are arranged in the cabins. A quick-connect male head is provided on the back of each on-board steamer, and a quick-connect female head is provided on the steam pipe corresponding to the on-board steamer. When the on-board steamer needs to be fed with steam, the quick-connect female head on the steam pipe must be connected to the quick-connect male head on the back of the on-board steamer. In the prior art, this is done manually by the operator.

[0003] Due to the high density of arrangement of the vehicle-mounted steamers in the cabin and the small gaps between the steamers, when the operator manually plugs and unplugs the quick connector, he needs to first put his arm into the gap between the steamers and then put his hand around the back of the steamer to manually plug and unplug it, which makes manual operation very difficult. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a quick-connect fastening device for a steam box and a steam pipe mounted on a portable square cabin vehicle, which can be plugged and unplugged without extending hands to the back of the steam box, thereby facilitating manual operation.

[0005] In order to solve the above technical problems, the utility model discloses a quick-locking device for a steamer and a steam pipe on a portable square cabin vehicle, comprising left and right steamer slides located on the left and right sides for the steamer to slide, and a driving mechanism that can drive the steamer to slide forward and backward on the left and right steamer slides, and the driving mechanism can lock the steamer on the steamer slides.

[0006] Furthermore, the driving mechanism includes a self-locking trapezoidal thread screw and an intermediate cross beam, the left and right steam box slides are located above the left and right sides of the intermediate cross beam, the front end of the self-locking trapezoidal thread screw is connected to a crank through a universal joint, the left and right ends of the intermediate cross beam are fixed with end beams, the upper part of the end beam is hinged with a connecting rod for connecting to the side wall of the vehicle-mounted steam box, and the lower part is fixed with a horizontal telescopic arm, the telescopic arm is provided with a mounting sleeve, the telescopic arm can slide in the mounting sleeve, a screw seat is fixed in the middle position of the intermediate cross beam, the front end of the self-locking trapezoidal thread screw can be rotatably mounted in the screw seat, the front part of the trapezoidal thread screw is screwed with a positioning plate, and the trapezoidal thread screw can be rotated by the crank to make the trapezoidal thread screw move forward and backward in a straight line, thereby driving the intermediate cross beam to move forward and backward.

[0007] As a further improvement of the present invention, the left and right steam box slides both include strip sliders, the bottom of the strip sliders are connected to a horizontal mounting plate, and the relatively outer sides of the strip sliders in the left and right steam box slides are connected to upwardly extending limit baffles.

[0008] Furthermore, a polytetrafluoroethylene sliding plate is fixed to the upper surface of the strip-shaped sliding block.

[0009] Furthermore, polytetrafluoroethylene slide plates are also fixed on the opposite inner side walls of the limit baffles in the left and right steam box slides.

[0010] As another improvement of the utility model, the front parts of the strip-shaped sliding blocks in the left and right steam box slides are widened toward the outside, and the front parts of the limit baffles are also inclined toward the outside accordingly.

[0011] Furthermore, the front parts of the strip-shaped sliding blocks in the left and right steam box slides both have downwardly inclined slopes.

[0012] The utility model has the following beneficial technical effects: first, the middle crossbeam can be driven to move forward and backward by turning the trapezoidal threaded screw by the crank, and the vehicle steamer can be driven to slide forward and backward along the left and right steamer slideways, so that the female quick connector on the steam pipe can be quickly connected with the male quick connector on the back of the vehicle steamer, and the self-locking trapezoidal threaded screw can lock the steamer at any position of the left and right steamer slideways. After the utility model is applied, the operator does not need to extend his hand to the back of the steamer to plug and unplug the quick connector; second, the relative outer sides of the strip sliders in the left and right steamer slideways are connected with the limit baffles extending upward, which can prevent the steamer from moving left and right 1. The steamer slides are arranged on the upper surface of the strip slider and the inner wall of the limit baffles in the left and right steamer slides, so as to reduce the resistance of the steamer when sliding. 2. The front parts of the strip sliders in the left and right steamer slides are widened outwards, and the front parts of the limit baffles are inclined outwards accordingly. It is simpler for the operators to lift the vehicle steamer onto the slides, and there is no need to align the limit baffles on both sides very accurately. 3. The front parts of the strip sliders in the left and right steamer slides are provided with downward inclined surfaces, so it is easier for the operators to lift the vehicle steamer onto the front end of the slides and push the steamer to slide.
