Aiming at the characteristics of the engine shell, the existing mounting method is improved, so that the engine can be successfully mounted at one time.

The invention relates to the technical field of installation of air supply components, in particular to an air supply port that can be directly installed on the ceiling, which solves the problem in the prior art that the installation of the air supply port is complicated and requires the assistance of multiple people. An easy-to-install air supply port, including a box body, two ports are respectively opened on opposite sides of the box body, the positions of the four ports are opposite to each other, and a limit block is arranged in the port, and the limit block is connected with the support rod through the support rod. The inner wall of the port is fixedly connected, and the side of the limit block away from the inner cavity of the box is provided with a limit card. The limit card is rotatably connected with the limit block. Has a fixed buckle. The present invention can reduce installation steps and labor costs during installation while ensuring that the air outlet is firmly installed.

The invention relates to the technical field of air supply component installation, particularly relates to an air supply outlet capable of being directly installed on a ceiling, and solves the problems that in the prior art, the steps for installing the air supply outlet are complex, and multi-person assistance is needed. An air supply outlet convenient to install comprises a box body, wherein thetwo opposite sides of the box body are each provided with two through openings; the positions of the four through openings are opposite in pairs; limiting blocks are arranged in the through openingsand are fixedly connected with the inner walls of the through openings through supporting rods; limiting clamping pieces are arranged on the sides, away from an inner cavity of the box body, of the limiting blocks and are rotatably connected with the limiting blocks; the length of each limiting clamping piece is not larger than the length of each limiting block; and a fixing buckle is arranged inthe box body. According to the air supply outlet convenient to install provided by the invention, the firm installation of the air supply outlet can be ensured, and the installation steps and the labor cost in the installation process are reduced.

The invention discloses an anti-collision expressway guardrail, which comprises a column, the column is fixedly connected with a fence through a connecting piece, the fence includes a front fence and a rear fence, the number of the connecting pieces is two, and the connecting piece includes a connecting cylinder and a connecting piece. Connecting the ring, one end of the connecting cylinder is fixedly connected with the column, the outer peripheral surface of the other end of the connecting cylinder is provided with a circular protrusion, and the inner peripheral surface of one end of the connecting ring is provided with a circular baffle, and the circular baffle The inner side of the ring-shaped protrusion is attached to the side of the column, the other end of the connecting ring is provided with a connecting plate, the cavity of the connecting ring is filled with buffers, and the two connecting plates are respectively connected to the two rear fences. The middle position of the arc part is fixedly connected, and the part of the connecting cylinder located between the upright post and the annular baffle is covered with a compression spring. The invention solves the technical problem that the existing highway guardrails have limited ability to absorb energy when a collision occurs.

The invention discloses an assembly-oriented frame part quick replacement type clamping device. The clamping device comprises an installing support, a circumferential positioning clamping mechanism, an axial supporting mechanism, after-assembly fixing compression mechanisms and a quick replacement locking mechanism; the circumferential positioning clamping mechanism is installed on an installing plate of the installing support, and the circumferential positioning clamping and releasing functions on a frame are achieved; the axial supporting mechanism is installed on the inner side of an installing plate, and the adjusting end of the axial supporting mechanism is in contact with the inner sides of the two end faces of a frame part to achieve axial supporting and limiting of the frame part; the two after-assembly fixing compression mechanisms are symmetrically installed on the upper side and the lower side of the installing support, and are used for achieving fixation and compression of parts installed on the two end faces of the frame part; and the quick replacement locking mechanism achieves 180-degree overturning of the frame part through positioning and fixing structures on the quick replacement locking mechanism. By means of the assembly-oriented frame part quick replacement type clamping device, lossless clamping and after-assembly fixing compression on the frame part can be achieved.
