The utility model discloses a kind of injection moulding jigs of die strip wire harness, it includes: lower mould and upper mould;Die strip wire harness structure;Injection channel;A plurality of first profiling grooves are opened in lower mould and communicated with injection channel, a plurality of second profiling grooves are opened in upper mould and communicated with injection channel, when upper mould and lower mould close mould, first profiling groove and second profiling groove form injection cavity, wire is passed through the injection cavity.The utility model is by being provided with a die strip wire harness structure in lower mould to be used for accommodating wire, provide good support to wire, effectively improve the traditional "point to line" support mode, substantially improve the yield of injection molding, it is suitable to be applied to various injection molding structures.The utility model adds injection channel between external injection molding machine and injection cavity, so that external injection molding machine can directly injection molding to injection channel, without secondary encapsulation to wire, substantially improve production efficiency, effectively enhance market competitiveness.

The application discloses a breather valve device suitable for a large-depth submersible, which comprises a hydraulic machine, a transmission mechanism and a breather valve disc; the hydraulic machine comprises a shell, a hydraulic cylinder, a crankshaft and a top rod, a pair of pistons and a rack connected between the pistons are arranged in the hydraulic cylinder, one end of the crankshaft is engaged with the rack through a gear, an eccentric section is hinged to one end of the top rod through a connecting rod, and the other end of the top rod extends out of the shell; the transmission mechanism comprises a short rod and a long rod, one end of the short rod is connected with the extending end of the top rod through a thread and a conical pin, the other end of the short rod is connected with one end of the long rod through a ball hinge structure, and the other end of the long rod is matched with a fisheye support provided with a spherical bearing; and the breather valve disc comprises a valve disc, a cover nut and an adjusting nut. The application has the advantages of increased radial compensation capacity, increased axial adjusting range, good deformation coordination capacity, adaptability to large-depth environment, improved stability of the transmission rod, realized long-distance transmission, simple structure and stable transmission.

The present invention discloses a reverse storage umbrella, comprising a sleeve, wherein the inner side of the sleeve is movably connected with a support shaft, and the outer top end of the support shaft is fixedly connected with a folding mechanism, and the folding mechanism comprises a connecting plate, a rotating rod, a connecting rod, a support rod, an outer spring, a mounting block, a sliding groove, a sliding block, an inner spring and a limiting rope, wherein the outer top end of the support shaft is fixedly connected with the connecting plate, and the top edge of the connecting plate is fixedly connected with the rotating rod. The present invention cooperates with the connecting plate, the rotating rod, the connecting rod, the support rod, the outer spring, the mounting block, the sliding groove, the sliding block, the inner spring and the limiting rope, so that during the process of storing the umbrella, the umbrella only needs to be pulled downward to store the umbrella in the sleeve, and the operation is simple and fast, which avoids rainwater on the umbrella from splashing everywhere. At the same time, since the outer side of the umbrella is protected by the sleeve, the risk of damage to the umbrella is reduced, and the storage process of the umbrella is optimized.
