The first switch, the second switch and the reset groove are arranged in the hydraulic cylinder, so that the oil pressure sealing load of the hydraulic cylinder can be reduced, the service life of the hydraulic cylinder is effectively prolonged, meanwhile, after pressing is completed, demolding operation is facilitated, and the production efficiency is improved.

The utility model discloses a thickness measuring device for bipolar plate production, which comprises a measuring column, a sliding block and a measuring plate, the sliding block is slidably connected to the surface of the measuring column, the measuring plate is fixedly connected to the front side of the surface of the sliding block, the bottom of the measuring column is fixedly connected with a measuring mechanism, and the measuring mechanism comprises a reference platform. And the reference platform is fixedly mounted at the bottom of the measuring column. According to the utility model, the distance measuring sensor is used for automatically detecting the distance and transmitting data to the control panel, so that the intelligentization of the thickness measurement of the bipolar plate is realized, the workload of operators is greatly reduced, and when a large number of bipolar plate measurement tasks are performed, the measurement efficiency can be obviously improved, and the time and energy are saved; and meanwhile, the arrangement of the reference platform can ensure the flatness of the bipolar plate when the bipolar plate is placed, so that the problem that in the practical application process of the patent equipment, an operator needs to manually rotate the rotating block so as to push the threaded rod to fix the measuring block, and the operation process is relatively complicated is solved.

This invention relates to the field of medical device technology and discloses a surgical pack waste collection device, comprising a housing, within which three waste dispensing boxes are fixedly installed, arranged side-by-side in a front-to-back direction. A first waste chute and two second waste chutees are also fixedly installed on the housing. The inner cavity of the first waste chute communicates with both second waste chutees, and the first waste chute communicates with the middle waste dispensing box. The two second waste chutes communicate with the other two waste dispensing boxes respectively. Two valve mechanisms and a stiffness detection mechanism are provided within the first waste chute. This surgical pack waste collection device, within the waste collection box, utilizes the gradient stiffness detection mechanism to trigger different sliding rods based on the stiffness differences of the waste itself, thereby controlling the valve mechanisms located at the connections of different chutees, achieving automatic waste sorting and collection.

This invention provides an ultra-small multi-contact measuring device, comprising upper and lower housings with hollow interiors and accommodating chambers, and a measuring assembly housed within both. The measuring assembly includes four transmission components, each with a uniquely shaped lever having at least three ends at different heights, enabling measurement of the inner diameter of a shaft hole from multiple directions. The staggered distribution of the third ends of the multiple uniquely shaped levers avoids interference and improves measurement accuracy. A protrusion on the upper housing facilitates insertion into the shaft hole, with the first end extending into the protrusion to accurately sense changes in the shaft hole's inner diameter. The sensing component incorporates a lifting structure, allowing for minute adjustments of the contacts to accommodate shaft holes of different sizes. The lower housing features a dust-blowing structure to keep the device clean and reduce operating temperature. Furthermore, a first locking screw ensures stable installation of the central rotating shaft, the L-shaped third end improves contact stability, and a spring forms an elastic reset system, enhancing measurement efficiency.

The utility model discloses centrifugal heat abstractor rubber pipe built -in opposing open type check valve relates to valve related technical field, the utility model discloses a barrel, the inside of barrel is provided with two groups of abutment and the valve piece of circular setting, the position of two groups of valve piece abutment is provided with the central shaft, and two groups of valve piece side wall correspond the upper and lower parts fixed with the rotating ring board of central shaft, and every rotating ring board all sets up on the central shaft, and the middle position of central shaft sets up two groups of the torsional spring of upper and lower settings. The utility model discloses two groups of valve piece and central shaft adopt the opposing open type structure, realize in limited space and increase flow, reduce flow resistance, and through the cooperation of torsional spring and valve piece, can make valve piece have the function of automatic reset, to realize automatic plugging treatment to barrel.

The probe for the computerized flat knitting machine is an elastic probe, and the elastic structure with the automatic reset function and the buffering function is integrally arranged on the probe. The utility model also relates to a broken needle alarm device, which comprises two probes arranged on the left and right of the machine head through insulating bases, an alarm control assembly, the probe is an elastic probe, the elastic structure with the automatic reset function and the buffering function is integrally arranged on the probe, the upper portion of the probe is connected with a weak current lead, and the machine head moves left and right on the needle plate to realize knitting. When the probe lower portion and the broken needle needle foot falling from the needle plate contact, the circuit of the alarm control assembly is connected to realize the broken needle alarm. The elastic probe can effectively reduce the impact force of the needle foot contact and automatically reset after the broken needle alarm is removed. In addition, the probe is arranged at the inner bottom plate of the machine head of the computerized flat knitting machine and located between the left and right sides of the needle lifting cam and the needle returning cam, so that the detection of the broken needle is more timely and accurate, and the knitting product quality is improved.
