The invention discloses a pressing material tensioning device, which comprises an upper pressing wheel (1) and a lower pressing wheel (2), and also includes an upper bottom plate (3) and a lower bottom plate (4). The bottom of the upper bottom plate (3) A cylinder (5) is arranged downward, and the cylinder (5) is connected with the upper pressure roller (1), and the lower pressure roller (2) is arranged on the lower bottom plate (3), and a buffer spring (6) is also arranged under the lower bottom plate (3). ), the upper pressure roller (1) can be pressed on the lower pressure roller (2) by the cylinder (5). The present invention presses the upper pressure roller on the lower pressure roller to press the film and achieve the tensioning effect at the same time, and the buffer spring under the lower bottom plate can reduce the pressure of the upper parts, so that the service life of the device is longer.

The invention discloses a tensioning device and a compressor provided with the same. The tensioning device comprises fixing plates, a connecting rod with one threaded end, a stop plate with a through groove and a nut, wherein one end of the connecting rod is hinged to the fixing plates while the other end with a thread passes through the through groove of the stop plate, the nut is in thread fit with the tail end of the connecting rod and is screwed into the thread, a circumscribed circle diameter of the nut is greater than a width of the through groove, the fixing plates are hinged to a base and are fixed on the compressor, and the stop plate is fixed on the base. The fixing plates can drive the compressor to rotate by being hinged to the base.

The present invention relates to the technical field of intelligent terminals, and discloses a torque balance counterweight mechanism of an intelligent barrier gate, which includes a core shaft and a gate lever body fixedly socketed outside the core shaft, and a connection block is fixedly socketed outside the core shaft. One side of the connecting block is fixedly connected with a balance bar, the front of the balance bar is provided with a moving chute, the end of the balance bar is provided with a counterweight positioning bar, and the counterweight positioning bar is fixedly installed on the inner bottom of the barrier gate chassis, and the counterweight positioning The front of the bar is provided with a limiting groove. The present invention replaces the traditional tension spring counterweight by setting a counterweight cable that is always tensioned, so that the tensioned counterweight cable is always equal to the action force and reaction force, and can ensure the real-time torque counterweight balance of the brake lever body , so that no additional impact amplitude will be brought by the counterweight when the brake lever body is turned in an emergency stop. In the case of heavy traffic flow, the brake lever body can be carried out smoothly when lifting the lever, dropping the lever, and lifting the lever in an emergency stop. Effectively guarantee the stability of the turnstile transmission system.

The present invention relates to the technical field of reducers, in particular to an intelligent oil leakage detection and recovery system for heavy-duty equipment reducers, comprising: a flexible body with a recessed area and a connecting part; The bottom is sealed or opened, and the sealing plate is connected with a pipeline; the sealing plate is located on one side of the tank body and is equipped with a filter plate to filter the oil; an elastic connection structure is set between the sealing plate and the tank body for sealing the sealing plate Tension to the tank body, the bottom of the side wall of the tank body is provided with an electromagnetic structure, which obtains magnetism when energized and repels the first permanent magnet on the sealing plate to obtain an open end; it is set between the sealing plate and the bonding surface of the filter plate There is a pressure sensing sheet, and the sensed pressure value is used as the basis for electromagnetic structure control and oil leakage detection. The invention can realize the effective filtering and recycling of the oil leakage, and can detect the amount of oil leakage, so that urgent problems can be quickly discovered and effectively treated.

The invention discloses a cloth tensioning device for an embroidery machine for cross-stitch textile processing, relates to the technical field of textile embroidery, and solves the problem that the existing cloth has ripples during the tensioning process, and at the same time, the roller shaft is prone to rotation. The movement of the cloth, the tensioning effect is not good, and the problems that affect the processing quality include the main body of the bracket; the tensioning sliding seat, there are four sets of tensioning sliding seats, and the four sets of tensioning sliding seats are respectively slidably connected to the four corners inside the main body of the bracket. The inner side of the tensioning slide seat is provided with a cloth clamping mechanism; there are four sets of sliding drive assemblies, and the four sets of sliding drive assemblies are respectively slidably connected to the inner sides of the four corners of the main body of the bracket. The invention avoids the loosening or moving of the cloth, realizes the clamping of the cloth through the parallelogram of the hinge, ensures the parallel clamping of the cloth, effectively avoids the pleats of the cloth, ensures the embroidery quality, and has good economic benefits.

The invention relates to an integrated transport tool for vehicle body large components of a rail transit vehicle. The integrated transport tool comprises a bearing base, a middle support frame, a top cover frame and a plurality of tension devices, wherein the bearing base, the middle support frame and the top cover frame are fixed together sequentially from bottom to top to form a bearing whole, at least two vehicle top large components or at least two sets of vehicle body side wall large components can be placed in the bearing whole, and one vehicle top large component corresponds to one set of vehicle body side wall large components; the length of the bearing whole is matched with the length of the vehicle top large components, and the width of the bearing whole is matched with the width of the vehicle top large components; the plurality of tension devices are symmetrically mounted on two sides of the bearing whole. The integrated transport tool can save the transport cost effectively, the structural design is reasonable, trivial connecting means are not needed, the tool can perform whole hoisting, conveying and storing after being fixed into a whole by the tension devices, is convenient and fast, and saves manpower and material resources for loading and unloading; besides, the integrated transport tool can be used for product storage, has diverse functions and adapts to various conditions well.
