The utility model discloses a buffer type taekwondo protective helmet which comprises a helmet body and further comprises side frames detachably arranged on the two sides of the helmet body and protective plates movably arranged on the side frames, and buffer assemblies used for buffering the protective plates are arranged at the upper position, the lower position, the left position and the right position of one side of each side frame. Buffering is carried out through cooperation of the side frame, the protection plate and the buffering assembly, the buffering effect is better than that of a traditional material, the buffering stroke is longer, ventilation is better, force transmitted from the protection plate can be secondarily buffered through the rubber groove body, the safety of the helmet is improved, and the service life of the helmet is prolonged. The side frames can be conveniently and quickly disassembled and assembled through the T-shaped grooves and the T-shaped clamping blocks, replacement is convenient, the two sides of the head and the temples of a person can be better protected, and damage to the two sides of the head and the temples caused by side kicking of high legs is effectively relieved.

The invention provides an elastic body expansion packer self-adaptive to a well diameter and a using method, and belongs to the technical field of packers. Comprising two fixing seats, an inner supporting core, a rubber sleeve, a connecting pipe, a central pipe and an upper connector, two sliding grooves are symmetrically formed in the inner side wall of the lower fixing seat, a lower connector is arranged in the lower fixing seat, an adjusting assembly is arranged between the connecting pipe and the central pipe, buffering assemblies are arranged between the sliding grooves and the lower connector, and the rubber sleeve is arranged in the lower fixing seat. The sliding sleeve is driven to axially move downwards through the adjusting assembly and the rotating center pipe, the distance between the two inner supporting cores is compressed, axial extrusion is applied to the rubber sleeve to promote radial expansion of the rubber sleeve, and the rubber sleeve effectively adapts to the large well diameter within a certain range. The position of the second sliding block is synchronously adjusted through rotation of the buffering assembly and the center pipe so as to increase the buffering stroke of the spring, self-adaptive protection with the larger hole diameter and the stronger buffering is achieved, and the structural durability is improved.

This utility model provides a hinge and a refrigerator including the same. The hinge includes: a first fixed base; a second fixed base; a transmission assembly; and a buffer assembly, which is mounted on the first fixed base or the second connecting member and extends toward the fifth connecting member. A buffer mating part is provided on the side of the fifth connecting member facing the buffer assembly. The buffer assembly is configured to switch from a non-active state to an active state when the buffer mating part abuts against the buffer end face of the buffer assembly during the closing process of the door. The fifth connecting member is the rod used to cooperate with the buffer assembly to achieve the buffering effect. During opening and closing, the fifth connecting member bears a smaller weight of the door, which helps to ensure the overall strength of the hinge. Mounting the buffer assembly on the first fixed base or the second connecting member increases the buffer stroke of the buffer assembly, enabling it to maintain a better buffering effect even when the door speed changes abruptly, thereby reducing or preventing damage to the refrigerator door and cabinet.

This invention belongs to the field of lead screw transmission technology and discloses a lead screw end limiting and buffering structure, including a lead screw and a limiting and buffering device. The limiting and buffering device is located at the end of the lead screw. When the nut on the lead screw moves to the end of the lead screw, the limiting and buffering device first limits the axial and rotational movement of the nut. When the limiting torque set by the limiting device is exceeded, the limiting device fails, thereby buffering. The buffer is located between the fixed part and the rotating part. The closer the distance between the fixed part and the rotating part, the greater the force exerted by the buffer on the rotating part. During normal operation, this invention achieves a reliable mechanical limiting function through the limiting pin, with high limiting accuracy. Under abnormal impact conditions, the limiting pin fails at the set torque threshold, limiting the peak instantaneous impact load below the set value, effectively protecting the lead screw, nut, and other structural components from damage, and avoiding the problem of excessive impact load generated by rigid limiting structures.

The utility model belongs to the field of machinery, and relates to an elastic plate hole clamping and adjusting device which comprises a lug hole penetrating elastic plate, a swing arm connecting piece, a supporting wheel swing arm, a lug hole penetrating piece and a lug plate blocking shifting pin, the lug hole penetrating elastic plate comprises a lug plate penetrating hole, a shifting pin penetrating and blocking sleeve is arranged at one end of the swing arm connecting piece, and a supporting wheel swing arm connecting structure is arranged at the other end of the swing arm connecting piece. The ear perforating piece is provided with a clamping and sticking elastic plate piece and a perforating ear, the perforating ear penetrates through the ear penetrating plate hole, the penetrating and blocking movement pin shaft sleeve penetrates through the ear penetrating plate hole, and the ear blocking plate movement pin penetrates through the perforating ear and the penetrating and blocking movement pin shaft sleeve, so that the clamping and sticking elastic plate piece is tightly attached to the ear penetrating hole elastic plate; the clamping and pasting elastic plate piece and the lug blocking plate moving pin prevent the perforated lug from falling off from a lug penetrating plate hole from the two sides of the lug penetrating hole elastic plate, the supporting wheel rocker arm is pushed by external force to be connected with the swing arm piece, the swing arm piece pushes the lug blocking plate moving pin, the lug blocking plate moving pin transmits the external force to the lug perforating piece, and the clamping and pasting elastic plate piece pushes the lug penetrating hole elastic plate to elastically deform and buffer. And the ear-hole-penetrating elastic plate is quickly straightened to reset by the buffer bounce of the ear-hole-penetrating elastic plate.

This utility model relates to the field of charging pile protection technology, specifically to an outdoor protective structure for charging piles, including a protective shell with a charging pile body disposed inside; ventilation components installed on both sides of the protective shell for heat dissipation; and anti-collision components installed on both sides of the protective shell for preventing the protective shell from being impacted by external forces. Compared with the prior art, this application achieves dustproof, waterproof, and heat dissipation through a slidingly adjustable ventilation component, and uses anti-collision components with rollers and springs for impact energy absorption and automatic reset, offering advantages such as adjustable protective performance, strong impact resistance, high heat dissipation efficiency, and convenient maintenance.
