Description

Technical Field

[0001] The utility model belongs to the technical field of chain transmission, and in particular relates to a shaft and chain plate transmission structure. Background Art

[0002] At present, in the prior art, the support frame for the skewers in the barbecue oven is a frame with a hole in each of the vertical plates on both sides of the support frame. One end of the skewers is first inserted into one hole, and then the other end of the skewers is inserted into another corresponding hole after a slight retreat. When a large number of skewers are grilled in the barbecue oven, the skewers are inserted into the holes one by one, and then the skewers are taken out of the holes one by one after the grilling is completed, which consumes a lot of energy, is slow to operate, and is time-consuming. At the same time, the transmission structure inside the existing oven is a gear and chain, the wheelbase cannot be adjusted, the number of teeth must be odd and cannot be used when the number of teeth is too small. Due to the volume limitation of the barbecue oven, the number of teeth is greatly limited, the transmission effect in the barbecue oven is poor, the production and processing technology is complicated, and the production cost is high. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a shaft and chain plate transmission structure, which solves the problems in the above-mentioned background technology.

[0004] The purpose of the utility model is achieved as follows: a shaft and chain plate transmission structure, which includes a driving component, the driving component is connected to a chain component, the chain component is connected to an automatic clamping component, the automatic clamping component includes a fixed shaft, the peripheral outer wall of the fixed shaft is rotatably connected to a bent left arm and a bent right arm, and the left arm and the right arm are arranged correspondingly, the upper end of the left arm is fixedly provided with a left clamping head, the upper end of the right arm is fixedly provided with a right clamping head, and the lower ends of the left arm and the right arm are connected with a telescopic component. When in use, the chain component is driven to move by the driving component, and the movement of the chain component drives the left clamping head and the right clamping head of the automatic clamping component to automatically open or close, eliminating the process of manually inserting or pulling out the two ends of the string rod one by one into the hole of the carrier frame, and the operation speed is fast, saving manpower.

[0005] Further, the telescopic assembly includes a connecting shaft, the lower ends of the left arm and the right arm are both rotatably connected to the outside of the connecting shaft, the inner end of the connecting shaft is fixedly connected with an auxiliary block, and the side wall of the auxiliary block is fixedly provided with an inner cylinder; the side wall of the fixed shaft is fixedly provided with an outer cylinder, the inner bottom surface of the outer cylinder is fixedly connected with a spring, and the other end of the spring is fixedly connected to the inner bottom surface of the inner cylinder, and the outer diameter of the inner cylinder is smaller than the inner diameter of the outer cylinder. When in use, the inner wall of the barbecue oven is provided with a driving protrusion, and when the driving assembly drives the chain assembly, the automatic clamping assembly and the telescopic assembly to move synchronously, the auxiliary block of the telescopic assembly is squeezed by the driving protrusion, the inner cylinder moves toward the inside of the outer cylinder, the spring is compressed, and the inner cylinder is retracted into the outer cylinder. When the inner cylinder is retracted toward the inside of the outer cylinder, the auxiliary block drives the connecting shaft to move, and the connecting shaft drives the left and right arms to fold, thereby realizing the opening of the left and right clamps. When the inner cylinder moves outward inside the outer cylinder, the auxiliary block drives the connecting shaft to move in the opposite direction, thereby realizing the closing of the left and right clamps. When the left clamp head and the right clamp head are opened, the two ends of the string rod are put in. After the string rod is put in, as the driving component drives the movement of the chain component, the left clamp head and the right clamp head are automatically closed to clamp the string rod.

[0006] Furthermore, the left support arm includes a left upper arm and a left lower arm, and the lower end of the left upper arm is rotatably connected to the upper end of the left lower arm via a pin shaft; the right support arm includes a right upper arm and a right lower arm, and the lower end of the right upper arm is rotatably connected to the upper end of the right lower arm via a pin shaft.

One side of the three-sided driving block contacts the side wall of the plate body, and the force is transmitted to the side wall of the plate body through the side wall of the three-sided driving block, thereby driving the plate body to move. The movement of the plate body drives the transmission protrusion to move, and then drives the automatic clamping assembly to move. A complete chain assembly is formed by connecting a plurality of plate bodies with a female connector at the left end of the plate body, and connecting a plurality of plate bodies with a male connector at the right end of the plate body.
