This utility model relates to the field of food processing technology, specifically a conveyor shelf for an oven. The conveyor shelf includes a shelf body, which is composed of a panel and support plates. Two support plates are symmetrically arranged on both sides of the panel and integrally formed with it. Each support plate is inclined from both ends towards the middle, forming a crease. The panel has through holes, and both ends of the panel extend outwards to form a fixing plate with mounting holes. This utility model features a simple structure, reasonable design, convenient installation, high installation efficiency, good stability, and long service life, making it worthy of widespread promotion and application.

The utility model provides a trimming lens and an optical lens having the same, the trimming lens comprises a first surface, a second surface and an outer ring surface, the outer ring surface is provided with at least one trimming surface, the trimming surface comprises a first diagonal plane and a second diagonal plane, the surface of the first diagonal plane and the surface of the second diagonal plane are both provided with tooth space structures, and the tooth space structures are arranged in the first diagonal plane and the second diagonal plane. The distance between the tooth crest and the central axis of the trimming lens is the largest, the distance between the tooth valley and the central axis of the trimming lens is the smallest, and the included angle r1 between the first diagonal plane and the central axis of the trimming lens and the included angle r2 between the second diagonal plane and the central axis of the trimming lens meet the formula of 1.3 lt; r1 / r2lt; 2.7, 2.7; the tooth crest distance a, the distance b between the tooth crest and the tooth valley and the included angle theta between the tooth valley of every two adjacent tooth groove structures meet the condition that 0.05 mm < = (a-b) * tan theta < lt >; and the thickness is 0.18 mm. The utility model solves the problem that the small size and stray light improvement of the optical lens in the prior art are difficult to consider at the same time.

The on-site liquid preparation device comprises a moving trolley, a dissolving tank and a circulating water pump, the dissolving tank and the circulating water pump are arranged on the moving trolley, a feeding port is formed in the top of the dissolving tank, an input port is formed in one end of the dissolving tank, an output port is formed in the other end of the dissolving tank, a sealing cover is detachably installed on the feeding port, and the circulating water pump is arranged on the moving trolley. A liquid inlet pipe is installed on the input port, a liquid outlet pipe is installed on the output port, the circulating water pump is installed on the liquid inlet pipe, and the liquid inlet end of the liquid inlet pipe and the liquid outlet end of the liquid outlet pipe are each provided with a conveying tank connector. The on-site liquid preparation device for oil well plug removal has the advantages of being scientific in design, easy to operate, high in safety and high in practicability.

The invention relates to the technical field of medical instruments, in particular to an anorectal disease postoperative continuous flushing device which comprises a base and a support connected to the top of the base, a back cushion is arranged on the support, a groove is formed in one side of the support, a waterproof mechanism is arranged on the support, and the waterproof mechanism is used for preventing flushing water from overflowing; a drainage mechanism is arranged below the groove; a flushing mechanism is connected to one side of the groove, and a plurality of nozzles are connected to the flushing mechanism; a positioning mechanism is arranged on the spray head and is used for fixing the spray head in the leakage pipe; the positioning mechanism not only can guarantee the stability of the flushing process, but also avoids the situation that medical workers need to hold the flushing mechanism in the whole process during flushing, the flushing operation difficulty is reduced, flushing water is prevented from overflowing through the waterproof mechanism, the cleaning workload of the medical workers is reduced, and the flushing efficiency is improved. And sewage after flushing can be discharged into the sewage tank from the sewage pool through the drainage mechanism, so that the possibility of cross infection is reduced.
