High-reliability flexible plate and assembling system thereof

The invention relates to a high-reliability flexible plate and an assembling system thereof. The flexible plate comprises a main via hole, a standard pad, a non-standard pad, a through hole, and a silk-screen. The assembling system comprises a circuit board, a bottom plate, an assembly fixture and a pin. The circuit board comprises a pad, a positioning hole and a mounting hole. The pin is secured on the circuit board and is inserted into the through hole of the flexible plate so as to position the flexible plate. The fixture comprises an insulated pressing block, a sliding block, a driving rod, a supporting base, a supporting beam and a compression spring. During the upward displacement of the driving rod, the compression spring arranged in the sliding rail of the supporting base applies an upward pressure on the sliding block, and then the sliding block drives the insulated pressing block to move upwards. Meanwhile, the driving rod arranged on the supporting beam moves downwards to drive the sliding block and the insulated pressing block to move downwards inside the sliding rail of the supporting base. Therefore, the flexible plate and the circuit board are compressed and assembled. The high-reliability flexible plate easily meets the industry standards, and is easy to use, easy to manufacture and test, and reliable in performance.

Femoral Stem for Artificial Hip Joint and Artificial Hip Joint Including the Same

A femoral stem 2 for artificial hip joint is provided that is capable of tightly fixing a greater trochanter and is suitable for treatment of transcervical fracture where it is necessary to fix the greater trochanter. The femoral stem 2 comprising: a stem member 20 including a distal part 21 of the stem member which is inserted in a medullary cavity of a femur and fixed therein and a proximal part 22 of the stem member which has a neck 26 for fixing an artificial head and is positioned at a proximal end of the distal part, the distal part and the proximal part being integrated or separable; a plate fixing portion 36 which is detachably attached at a top of the proximal part; and a greater trochanter plate 3 for depressing the greater trochanter 71, the greater trochanter being fixed to the plate fixing portion 36 at a certain angle or fixed to the plate fixing portion so as to adjust an angle. Since the greater trochanter plate 3 is fixed onto the femoral stem 2 of the present invention, the greater trochanter is tightly fixing and thus the fixation can be stabilized. Furthermore, since the greater trochanter plate 3 is fixed at the top of the proximal part 22, the greater trochanter plate 3 covers the top of the greater trochanter 71 when the greater trochanter 71 is fixed. Therefore upward displacement of the greater trochanter by a gluteus medius musculus can be effectively suppressed.

Bilaterally symmetric abbreviated condom

Securement of a condom to the glans penis is facilitated by a pair of bilaterally symmetric areas provided for the lobes of the glans penis. It is recommended that the bilateral convex shape of the two lobes of the glans penis be adhered to by a close fitting shape molded into the condom which will resist accidental upward displacement. A viscous layer upon the interior surface enhances the suction characteristics in providing a greater cohesion coefficient between the condom and the skin contacted. A plurality of vacuum cups molded into the interior surface of the condom is also suggested. An expansible seminal fluid reservoir is provided, preferably located between the lobes of the glans are upon the tip of the condom. The resistance to accidental upward displacement provided by the suction areas adhered to the glans permit the condom to be severely abbreviated in length which allows greater sensitivity and a stronger condom more resistant to tearing during use than a conventional full length latex condom. Correct positioning may be facilitated by a reversible margin proximate the open rear edge which fits into the sulcus behind the corona. A circumferential adhesive layer is recommended to obtain a seal against fluid transmission and the use of a thin film backing upon the same further facilitates positioning of the condom. Manufacture by injection molding is suggested as is use of a plastic which may be transparent.

Mine horizontal hydraulic bracket

The invention discloses a horizontal hydraulic support for mines, which includes a support plate, a hydraulic cylinder is fixed at the bottom of the support plate, the bottom of the hydraulic cylinder is connected to a damping cylinder, the damping cylinder is also connected to the bottom of a pressure cylinder, and the top of the pressure cylinder is connected to an air pump; in the present invention, Since the hydraulic oil in the hydraulic cylinder under the support plate is connected to each other, according to the principle of the connector, the hydraulic pressure will keep the support plate level at this time, the air pump will inflate the pressure cylinder, and the high-pressure gas will push the hydraulic oil in the pressure cylinder into the sleeve, pushing the first The first piston moves upwards, the air pump reverses, and the gas in the pressure cylinder is pumped out, so that the support plate can be lowered; when vibration occurs, the first piston moves up and down in the sleeve due to the force of the vibration, and presses the hydraulic oil in the damping cylinder. Due to the S-shaped distribution of the damping hole, the hydraulic oil rubs against the inner wall of the damping hole when it passes through, converting the mechanical energy of the vibration into internal energy, and the blocking plate in the damping hole can play a damping role, which can effectively suppress the vibration .
