This utility model discloses a tooling for drilling the gear ring of a power transmission in engineering machinery. It includes a base plate, a mandrel, a notch, a positioning base, a positioning hole, a positioning shaft, a V-block, a bushing, a handle, a connecting shaft, a threaded hole, a threaded thread, a spring, a workpiece disassembly / assembly partition, a round hole, a clamping bolt hole, a clamping bolt, and a clamping block. This utility model utilizes a mandrel that is detachably mounted on the base plate. The handle shaft, bushing, positioning shaft, spring, and V-block are mounted on the detachable positioning base. The clamping bolt and clamping block are then mounted on the base plate. This structure facilitates assembly and replacement, allowing for convenient positioning and clamping of the large gear ring before machining. This reduces machining time, simplifies machining, lowers costs, and improves machining efficiency.

The utility model discloses a water rocket parachute opening device which comprises a connecting sleeve head and an outer cover which are arranged between two rocket bodies, the two rocket bodies are connected through a butt joint, the connecting sleeve head is arranged on the butt joint in a sleeved mode, a support used for installing a parachute opening control piece is arranged on the side face of the connecting sleeve head, and the outer cover can surround the rocket bodies to form a parachute containing area. An elastic pull rope is connected to one side of the outer cover, and a mounting hole matched with the parachute opening control piece is formed in the outer cover; the side opening type parachute opening structure is adopted, the parachute bin body is constructed on the basis of an original water rocket, it can be guaranteed that the parachute is smoothly opened, device components are greatly simplified, manufacturing cost is reduced, operation is convenient and fast, and the side opening type parachute opening device is more suitable for being widely used in teaching demonstration.

The utility model provides a reagent box fixed structure for thrombin determination relates to reagent box technical field, including main box body, the front side middle of main box body top is fixed and is provided with magnetic attraction piece, the top of main box body is hingedly provided with rotating cover, the front side below middle of rotating cover is fixed and is provided with trapezoidal iron piece, the inside lower corner of main box body is integrally provided with four groups of thread pile, and the assembly screw rod is provided with in all through screw connection in thread pile, the inside of main box body is provided with the locating disc of anastomosis sliding, and the ring seat screw hole is opened in the middle array of locating disc, in the utility model, adopt double buffering structure, can strengthen safety protection, the elastic fixing and buffer of air bag wrapping test tube, cooperate bottom rubber bottom pad, can all -round absorption shock impact in the process of loading, transportation, and can avoid the gap of test tube and slot, improve stability, top rubber top pad ensures test tube seal, prevents liquid leakage, guarantees test tube safety to the maximum extent.

The utility model discloses a kind of plate assembly, gear box and stepping motor. Plate assembly includes upper pole plate and gear plate integrally injection molded in the side of the upper pole plate;Gear plate has fastening part, for fastening the cover plate of assembled gear box. The plate assembly provided by the utility model, which integrally injection molds the upper pole plate and the gear plate together, optimizes the assembly structure, optimizes the radial collision that may be generated in the low-frequency operation process of motor to cause motor abnormal sound;Gear plate is assembled in gear plate, and the noise of separate gear box body model can be tested (i.e. detecting the noise problem of gear box), without gear box noise detection after the completion of the overall assembly of existing motor, optimize product quality detection method, so that its gear box body can independently detect whether its noise meets quality requirement.

This utility model discloses a rubber plug for wiring harnesses such as high-mounted brake lights. The plug (1) is divided into a plug head (101) and a plug body (102), which are connected. The plug body (102) has a W-shaped cross-section and an annular clearance cavity (2) on its inner side. The plug head (101) is frustoconical, and the end of the plug head (101) with a larger diameter is connected to the plug body (102). The body (102) is frustum-shaped. The side with the larger diameter of the body (102) is connected to the plug head (101). The cross-sectional shape of the clearance cavity (2) is trapezoidal. The clearance cavity (2) is located on the side where the body (102) is connected to the plug head (101). By setting clearance space in the rubber stopper (1), the body of the rubber stopper (1) has greater compressibility without affecting the original sealing performance. This facilitates the assembly structure, reduces material usage, and lowers production costs.
