This utility model relates to the field of aluminum profile splicing and assembly technology, and in particular to a quick-installation aluminum profile assembly, comprising two aluminum profiles stacked from top to bottom. Two horizontally spaced locking strips are inserted into the cavities at the mating surfaces of the two aluminum profiles. Locking screws are screwed into threaded holes on both sides of each aluminum profile. Each locking screw is used to push outwards a mating elastic locking element and lock it to the corresponding locking strip. This assembly can quickly stack and fix two adjacent aluminum profiles as needed. During fixing, corresponding elastic locking elements and locking strips can be pre-installed as needed. Then, by screwing in the corresponding locking screws, the elastic locking elements are pushed and aligned with the locking strips, ensuring the quick-installation assembly of the two adjacent aluminum profiles and the stability after installation.

The present disclosure relates to the technical field of injection molding machines, and one embodiment of the present disclosure provides a quick mold changing device of a new plastic line box injection molding machine, which is applied to an injection molding machine body, two molds are arranged in the injection molding machine body, and the quick mold changing device further comprises two mounting plates, a clamping frame and a support plate, the two mounting plates are arranged on the injection molding machine body, the two molds are arranged on opposite sides of the two mounting plates, the clamping frame comprises two groups, one group of the clamping frame is arranged on each of the two mounting plates, each group of the clamping frame is arranged on the two mounting plates through a clamping mechanism, the clamping mechanism is used for driving the clamping frame to clamp the mold, and the support plate is arranged on each of the two mounting plates through a moving mechanism, the moving mechanism is used for driving the support plate to move against the mold. Through the above technical solution, the technical problem that the mold is time-consuming and labor-consuming to disassemble and the efficiency of mold replacement is reduced in the prior art is solved.

The utility model discloses a kind of suction rubber of blowout preventer box, it relates to petroleum exploitation technical field, specifically a kind of suction rubber of blowout preventer box, including two matrix, framework, the upper end opening inner diameter of matrix is greater than lower end opening inner diameter, the matrix is constituted by straight cylinder section, conical cylinder section, anti-jamming section, the upper and lower ends of straight cylinder section are respectively fixedly connected with conical cylinder section, anti-jamming section;By adopting two matrix, two matrix are constituted after being spliced by jointing a cylinder structure.In the replacement of suction rubber of blowout preventer box, it is not necessary to disassemble or move sucker rod, just replace two matrix in blowout preventer box, two matrix are constituted after being spliced by jointing a cylinder structure, the cylinder structure can embrace the outer lateral wall of sucker rod all around, greatly improve the disassembly replacement efficiency of suction rubber, avoid affecting project progress.

The utility model discloses a quick replacement filter core formula filter device, including filter main part, filter main part is by cylinder, flange, water inlet pipe, water outlet pipe, filter basket and top cover constitutes, and the filter basket is arranged in the cylinder, and water inlet pipe and water outlet pipe are respectively communicated on the both sides of cylinder, and the flange is connected in the top opening of cylinder, and the outer wall of flange is provided with a plurality of first notches, the utility model discloses the connection between two guide blocks, connecting axle, bolt and the ring nut of lifting, make the ring nut and bolt keep the state of connection under the condition, realize the rotating effect of bolt driving ring nut with connecting axle as the center, make the ring nut separate from top cover, and the thread section of bolt separates from second notched, realize the separation effect of top cover and flange, compared with prior art, can effectively avoid the complete separation between bolt and nut, thereby improve the disassembly efficiency of filter, realize the quick replacement effect of filter basket.

The invention belongs to the technical field of motorcycles, and mainly relates to a front mudguard mounting structure of a cross-country motorcycle, which comprises a bracket mounting plate arranged at the lower part of a steering column assembly of the motorcycle, the support mounting plate is of a polygonal plate structure, and turnup lug plates bent by 90 degrees are arranged at the two ends of a panel of the support mounting plate. A mounting hole is further formed in the flanging lug plate; projection welding nuts which are uniformly distributed are arranged at four corners of the top of the plate surface of the bracket mounting plate; step counter bores which are symmetrically arranged are also formed among the projection welding nuts; the bottom of the support installation plate is further provided with an installation auxiliary plate assembly connected with the support installation plate. By the adoption of the support mounting plate structure, a supporting system with the dynamic buffering capacity is constructed, the overall rigidity and connection stability of the front fender mounting structure are remarkably improved, the loosening risk is reduced, the production and manufacturing cost is reduced, the disassembly and replacement efficiency during maintenance is improved, and the service life of the front fender mounting structure is prolonged. And double benefits of function improvement and process optimization are realized.
