A novel automatic reset fixture, relating to the field of aging testing equipment technology, is used for aging testing of devices. From bottom to top, it includes a base plate, a PCB matching board, and a probe limiting plate capable of supporting the device. The PCB matching board has a number of auxiliary probes, and the probe limiting plate has through holes for the auxiliary probes to pass through. Fixture assemblies are respectively arranged on both sides of the PCB matching board. The fixture assemblies include a lower support plate, an upper pressure plate, a flipping plate, a lower pressure plate, two guide shafts, and two compression springs. This fixture is adapted to the automation, flexibility, and intelligent production needs of modern manufacturing, achieving an overall improvement in production quality, efficiency, safety, and control levels through technological optimization, providing reliable tooling support for the stable and efficient operation of the entire production process.

This utility model relates to the field of photovoltaic bracket purlin technology and discloses a photovoltaic bracket purlin connector, including an inclined beam. A purlin body is provided on the top of the inclined beam, and a slider is slidably connected to the inner wall of the inclined beam. A U-shaped frame is fixedly mounted on the side of the slider. The slider is moved in the inner wall of the inclined beam, and then the bottom of the purlin body overlaps the top of the slider. The outer edge of the limiting plate is driven by the adjusting rod to pass through the inner wall of the second sliding groove and the inner wall of the first sliding groove to the inner cavity of the circular groove. Then the adjusting rod is rotated and then released, thereby using the push plate to assist in pushing the outer edge of the limiting plate to the inner wall of the limiting groove, thereby assisting the purlin body to be erected quickly. The outer edge of the auxiliary plate passes through the inner wall of the auxiliary groove to the inner wall of the purlin body. Then the auxiliary plate is rotated so that the bottom of the auxiliary plate overlaps with the bottom of the inner wall of the purlin body, thereby further ensuring the stability of the purlin body erection.

The utility model provides an engine tray transfer machine which comprises a machine frame, a sliding table seat, a lifting driving device and a telescopic platform device, and the telescopic platform device comprises a telescopic platform, a bottom plate, a rail platform, a transverse driving assembly and a pair of traction chains. The telescopic platform and the rail platform are connected through traction chains, in the process that the transverse driving assembly drives the rail platform to transversely move, the rail platform drives the telescopic platform to move in the same direction through the traction chains on one side, and after the rail platform moves to the maximum moving stroke, the telescopic platform is driven to move in the same direction. As the traction chain has movement allowance relative to the track platform, the telescopic platform can still continuously move forwards along the track platform under the inertia effect at the moment, and the larger transverse movement distance relative to the track platform is achieved; the track platform is driven by a single power source to move, the telescopic platform further moves relative to the track platform through the traction chain between the telescopic platform and the track platform, the structure is simple, and the manufacturing cost is low.

The utility model belongs to the technical field of building construction equipment, concretely relates to a crane steel wire rope winding anti - disorder rope limiting device for building construction, including base, base and support plate one end fixed connection, support plate other end and support frame outside fixed connection. The utility model discloses be provided with electric push rod and pulley on the connecting frame, and the device passes through two pulleys when using crane steel wire rope, and control two electric push rod elongation makes two pulleys close to each other and carries out the clamping limit of steel wire rope, when winding the steel wire rope by using the winch, can utilize motor, reciprocating screw, reciprocating screw nut, translation board drive connecting frame and pulley left and right reciprocating translation, thereby utilize the translation adjustment steel wire rope's position of connecting frame, pulley, make steel wire rope can be along winch reel in turn winding, avoid the extrusion caused by the irregular messy winding of steel wire rope on the reel, effectively prolong the service life of steel wire rope.

This utility model discloses a positioning pillow in the field of medical pillow technology that can support a medical neck brace. It includes a headrest, a neck pillow, a raised cushion, a shoulder rest, and a neck brace. Addressing the needs of patients after cervical spine surgery, it adds an adjustable headrest, neck pillow, and shoulder rest. The headrest and neck pillow can be individually adjusted in height to suit the patient's head comfort and provide a more comfortable sleeping posture. A positioning groove is also added to fit the medical neck brace, making it more comfortable for patients to sleep with the neck brace while preventing it from sliding up and down. It does not restrict the patient's left and right head turning movements, providing a certain level of comfort while ensuring the neck brace limits the patient's neck in a set position. Even after the neck brace is removed, the device still provides neck restraint, preventing the patient from nodding or tilting their head back while sleeping, avoiding adverse neck movements during sleep, and protecting patients who have removed the neck brace while sleeping.
