The invention discloses a pre-stressed concrete compression pipe pile tension connector without an end plate. The pre-stressed concrete compression pipe pile tension connector without an end plate comprises an expansion shell, a first sealing cover, an expansion connecting pin and a wedge-shaped part, wherein a through groove penetrating through both ends is formed in the expansion shell, the through groove comprises an extending section and a clamping section, the inner diameter of the clamping section is larger than that of the extending section, a first sleeve is arranged at the end, corresponding to the extending section, of the expansion shell, and an inner thread is arranged on the first sleeve; the first sealing cover is fixed to the end, corresponding to the clamping section, outside the expansion shell, and a first through hole is formed in the first sealing cover; the expansion connecting pin comprises a connecting section and an expansion section, an expansion groove is formed in the expansion section, the expansion groove extends axially from the end part of the expansion part to the connecting section, the expansion section is divided into at least two parts through the expansion groove, and the expansion section extends into the expansion shell; and the wedge-shaped part comprises a head part and a tail part, the outer surface of the wedge-shaped part is graduallyclosed inward from the head part to the tail part, and the wedge-shaped part extends into the expansion section along the expansion groove from the tail part to expand the expansion section. According to the pre-stressed concrete compression pipe pile tension connector without the end plate, materials are saved, the structure is simple, but connection is more reliable, and use is more convenient.

The invention discloses an automobile temperature sensor, comprising a protective cover, a bracket is arranged inside the protective cover, a sensor is clamped in the middle of the bracket, an electric wire is arranged inside the sensor, and one end of the electric wire is connected to a thermosensitive resistance, the other end of the electric wire is connected to the tongue, the upper part of the protective cover is provided with a plug connector, the connection between the protective cover and the plug connector is provided with a sealing cover, and one side of the protective cover connects the wire body Injection connection with sensor. This kind of temperature sensor increases the service life of the temperature sensor, improves the stability between the temperature sensor and the wire body, reduces the cost, makes the overall use effect of the temperature sensor more obvious, and improves the response speed of the sensor head. It is simple and easy to install, and at the same time reduces the safety hazards existing in the car.

The invention discloses a rubber pipe discharging device. The rubber pipe discharging device comprises a feeding disc and a rubber pipe cut-off and discharging machine which are sequentially arranged. The rubber pipe cut-off and discharging machine comprises a conveying wheel set, a rubber pipe cut-off mechanism and a guide pipe for a rubber pipe to penetrate. The conveying wheel set is internally provided with a rubber pipe penetrating gap. The guide pipe comprises two sections, a cutter is correspondingly arranged between the two sections, an opening is formed in the pipe wall of the guide pipe in the axial direction, and the part, corresponding to the opening, of the guide pipe is provided with a laser sensor used for detecting the end portion of the rubber pipe. The rubber pipe discharging device is reasonable in structural design, feeding is conducted through double power sources, and it is guaranteed that the end portion of the rubber pipe is not prone to being pulled; belt conveying is adopted, the contact area is large, skidding is not likely to happen, and the rubber pipe cannot be subjected to extrusion deformation; the laser sensor is used for controlling the cut-off length of the rubber pipe, precision is high, and accuracy and reliability are achieved; and automatic rubber pipe cutting-off and discharging are achieved, the production efficiency is high, and cost is reduced.

The invention discloses an anti-extubation quilt, and relates to the technical field of medical supplies, the anti-extubation quilt comprises a quilt body and two widened edges, the quilt body can cover the body of a user and keep the body temperature of the user, the widened edges can separate the two arms of the user from a postoperative drainage tube, and one end of each widened edge is fixedly connected with the surface of the quilt body through a connecting part. During use, the two widened edges are located at the end, close to the head of the user, of the quilt body and located on the left side and the right side of the human body respectively, the width of each widened edge is larger than the distance between each connecting part and the edge of the quilt body, each connecting part is parallel to the body of the user, and a fixing device is arranged at the free end of each widened edge. And the widened edges can be fixed on the bed body by the fixing devices. According to the invention, the widened edges and the fixing devices are arranged, so that the restraint on the thoracic and abdominal postoperative patient is safe and effective, the patient can accept the restraint easily, and the comfort of the patient is improved.
