According to the fiberboard nail, the fixing effect is improved, the installation convenience is optimized, and the fiberboard nail has important practical value and application prospects.

The utility model relates to angle grinder technical field, concretely is a kind of angle grinder guard mounting structure, including shell, the inner side of shell is fixedly connected with mounting ring, the inside of mounting ring is equipped with installation groove, the inner wall front side of installation groove is detachably connected with cleaning ring, the inside of installation groove is rotatably connected with mounting cover, the lower side of the outside of mounting ring is equipped with limit slot, the inner wall lower side of limit slot is equipped with clamping groove, the inside of clamping groove is clamped with clamping block;By inside and outside two layers design to guard, and multiple clamping grooves are equipped on inner side guard, and then can use clamping block and install ring are clamped, and make clamping block can be clamped with clamping groove so that after installing guard, the rotation angle of mounting cover can be limited, and then not only make installation convenience better, and make installation stability higher, also make protection effect better.

The invention belongs to the technical field of cable mounting equipment, and particularly relates to an overhead mounting guide device in a cable well, which comprises a mounting plate and two groups of elastic guide devices mounted on the mounting plate. Each elastic guide device comprises a supporting wheel and two lateral wheels, a penetrating-out groove is formed in the mounting plate, and the wheel face of each supporting wheel is inserted into the corresponding penetrating-out groove and protrudes outwards. The two lateral wheels are vertically installed on the two sides of the supporting wheel and used for clamping the cable inwards together. The supporting wheels and the lateral wheels on the two sides form a three-point clamping structure, the friction coefficient is reduced through cooperation with the autorotation function, laying traction force is reduced, meanwhile, deviation or groove jumping in the cable traction process is prevented, and construction efficiency is improved. The combined structure of the transverse supporting spring columns and the sliding grooves achieves vertical buffering, the cooperation of the lateral supporting spring columns and the adjusting grooves achieves lateral buffering, traction impact force is absorbed through double buffering, sheath abrasion caused by hard dragging is avoided, and the service life of the cable is prolonged.

The utility model discloses an engineering machinery cooling module that is convenient to assemble and overhaul, which comprises a frame, a frame vertical bottom plate outer periphery side edge position integral bending has to the rear side extension's frame board, and the vertical bottom plate and the frame board that is located at the outer periphery side edge position enclose and form the cavity that the opening is towards the rear side, hydraulic oil cooler, water tank radiator, intercooler three wall -hanging type fixed in the rear end port position of frame, fan front end embeds and fixes in the fan mounting hole inside that is set up on the vertical bottom plate, and the fan rear end extends to the cavity inside, and the air outlet of fan is towards the front side. The frame is designed as a half-enclosed integral sheet metal structural member, which effectively reduces the total amount of raw materials and cost of the frame, does not substantially increase the total weight of the engineering machinery cooling module product, and is convenient to transport and install; the heat dissipation cooling element is wall-hungly fixed at the rear end port position of the frame, which is convenient to install and disassemble, and helps to substantially reduce the maintenance and overhaul time of the engineering machinery cooling module.

The utility model discloses a button structure, a button assembly and an electronic atomization device.The button assembly comprises a first shell, a button mainboard and an outer cover plate made of a hard elastic material, a first containing cavity is formed in the first shell, and an opening communicating with the first containing cavity is formed in the side wall of the first shell; the button mainboard is arranged in the first containing cavity and provided with button contacts corresponding to the opening, the outer cover plate is provided with a cover plate part and a first button part, the cover plate part is connected to the outer side of the first shell in a buckled mode and covers the opening, a first through hole is formed in the side wall of the cover plate part, and the first button part is provided with a first connecting arm and a first hand pressing part. One end of the first connecting arm is connected with the inner wall of the first through hole into a whole, the other end of the first connecting arm is connected with the edge of the first hand pressing part into a whole, and the first hand pressing part is suspended in the first through hole and is arranged corresponding to the button contact.

This utility model discloses an easy-to-install household gas alarm device, relating to the field of household gas technology. It includes an alarm body with an upper cover at its bottom. A lower cover is detachably connected to the bottom of the upper cover. Buffer cavities are formed on the inner walls of both ends of the upper and lower covers, and buffer protection blocks are movably installed inside these cavities. This utility model utilizes buffer cavities on the inner walls of both the upper and lower covers. A rubber protrusion is installed at the front end of the buffer protection block within each cavity, and a return spring is connected to its rear end. When installed, the pipe compresses the rubber protrusion. The rubber protrusion initially buffers the impact force through its elasticity. Simultaneously, the buffer protection block moves into the buffer cavity, compressing the return spring. The spring generates a counter-force to further offset the compressive force, preventing scratches, deformation, and other damage to the pipe due to excessive force. This protects the pipe and extends its service life.
