An extensible bed comprises a main bed body (9) and an extensible auxiliary bed body (8), wherein an auxiliary bed body (8) driving device is arranged in the main bed body (9). Therefore, when the auxiliary bed body (8) extends out, the bed body can be widened; when the auxiliary bed body (8) contracts into the main bed body (9), the bed body is recovered to original size. Thus, existing space can be enlarged under the situation that bed increase is needed, meanwhile it can be ensured that the auxiliary bed body (8) is stored in the main bed body (9) under the situation that bed increase is not needed, and space is effectively saved while the demand is met.

The invention discloses a method and device for mechanically fixing a dynamic extensometer in a high-temperature fatigue test. The method fixes two U-shaped plates with special V-shaped grooves on the surface of a fatigue sample by fastening screws, and the high-temperature dynamic The front end of the extensometer is embedded in two V-shaped grooves, which avoids the sliding of the dynamic extensometer during the fatigue test. The device is mainly composed of a thin plate and fastening screws. The thin plate has a special V-shaped groove. The device has a simple structure and is easy to process. The invention effectively avoids the sliding of the dynamic extensometer during the high-temperature fatigue test without changing the surface morphology of the fatigue test, accurately measures the deformation of the sample during the fatigue test, and ensures the smooth progress of the fatigue test. It has the characteristics of strong versatility, simple operation, easy processing and reusable device.

The invention relates to a wire terminal plug, which is equipped with a first plug and a second plug on the frame body of the heat dissipation system equipment; wherein the first plug is connected with the wire connected to the motor stator of the heat dissipation system equipment, and is fixed on the frame in a constant manner. On the body; the second plug is connected with the wire to be transferred, and its periphery is provided with buckle feet, and the corresponding buckle feet of the heat dissipation system equipment are provided with a buckle back hole for the buckle feet to be fastened. By adopting the above technical solution, the present invention can ensure the fixed position of the second plug on the one hand, and it will not fall off even if it is in a high-frequency vibration environment for a long time; It has the advantage of quick disassembly and assembly, and achieves the purpose of conveniently changing various wires.

The invention discloses a massager with a flexible frame. The massager comprises a massager body and a control board, wherein the massager bod comprises a silicone layer and a frame coated in the silicone layer; an elastic ring which can be deformed under an external force is arranged on the massager body; a vibration motor I and a battery are arranged at one end of the frame, and a vibration motor II and a charge head are arranged at the other end of the frame; and the control board is electrically connected with the vibration motor I and the vibration motor II. According to the C-shaped structure at the center of the silicone frame, the fixed position of power lines and control lines can be ensured, stretched deformation of single side of a massager fit hole cannot be stopped, and elastic deformation of a mount hole can be realized to adapt to different users; and due to use of the silicone frame, the whole massager has good flexibility, and the comfort and safety of the massager canbe promoted by matching with the external silicone coating.

The invention discloses an embedded part for a refrigerator, which comprises a body and grooves. A mounting space with an open rear side is defined in the body, a through hole is formed on the front wall of the body, the grooves are disposed on side walls of the body, and a first flange is formed at the edge of one side, which faces to the inner side of the body, of each groove. The embedded part in an embodiment of the invention is fixed firmly. In addition, punched holes on the refrigerator are omitted, cost is saved, the through hole brings convenience for fixing a screw, and the embedded part is simple in structure, convenient in installation and high in assembly efficiency. The invention further discloses the refrigerator comprising the embedded part.

The machine has a bearing block (51) inserted in a housing-fixed bearing (49) for movably bearing a fork lever. The lever is coupled with a relay e.g. engagement relay. Compensating and / or sealing elements (1, 2) e.g. sealing lips, are designed for clearance-free arrangement of the bearing block in the bearing. The compensating and / or sealing elements seal the bearing with the bearing block. The compensating and / or sealing elements are integrally designed with each other. The compensating and / or sealing elements are aligned along or transverse to a mounting direction (A). Independent claims are also included for the following: (1) a method for mounting an electric machine (2) a method for manufacturing an electric machine.

The invention relates to a stretchable bed with protective fences. The stretchable bed comprises a main bed body (9) and a stretchable auxiliary bed body (8), wherein a driving device for the auxiliary bed body (8) is arranged in the main bed body (9); when the auxiliary bed body (8) stretches out, the bed body is widened; when the auxiliary bed body (8) contracts into the main bed body (9), the bed body recovers to the original size; foldable protective fences are arranged on front and rear surfaces and rear side walls of the auxiliary bed body (8). Thus, under the condition of requiring bed addition, the present space can be expanded; the auxiliary bed body is specially suitable for being used as a bed for children; the auxiliary bed body (8) can be stored in the main bed body (9) under the condition of no bed addition, so that the requirement is met while the space is effectively saved.

The invention discloses a tool for detecting a steel die positioning pin of a CRTSIII type track slab. The top of a fixed cylinder base is connected with a top cover; a prismosphere mounting groove is arranged in the center of the upper surface of the top cover; a prismosphere is mounted in the prismosphere moutnign groove; a downward-protruded pressure spring positioning sleeve is arranged in the center of the lower surface of the top cover; a gripping rod for fixing the positing pin, an inverse cone body and the pressure spring are arranged inside the fixed cylinder base; a groove is arranged in the center of the inverse cone body; a pressure spring positioning sleeve is arranged in the groove of the inverse cone body; the upper part of the pressure spring is arranged in the pressure spring positioning sleeve; the lower part of the pressure spring is arranged in the groove of the inverse cone body; a slot hole corresponding to the length of the pressure spring positioning sleeve is arranged on the side wall of the fixed cylinder base; a connecting rod of a hand wheel connecting rod passes through the slot hole and is connected with the upper part of the side wall of the inverse cone body; a gripper at the lower end of the gripping rod surrounds the root part of the positioning pin; and the top end of the gripping rod is connected with the conical surface of the outer side wall of the inverse cone body in the mode of sliding contact. The tool can be used for converting the deviation of the steel die positioning pin of the track slab into the deviation of the center of a prism and has the advantages of simple structure, convenience in installation and accuracy in positioning.
