The inventive comprises aconnector (10) connected with a support rod (3), a guide rod connected above the connector (10), a weight (14) sheathed on the guide rod (12), a support plate (18) fixed on the upper end of the guiderod (12), a control device for lifting and releasing weight (14) arranged between the support plate (18) and the weight (14), a muffle (24) at a hole of the connector (10), a punch head (22) arrangedunder the muffle (24), a pressure sensor (26) between the punch head (22) and the muffle (24), a spring (25) in the muffle (24), and a bearing rod (11) supported in the muffle (24) via the spring (25). The invention can avoid artificial effect, standard test, accurate value, simple structure and easy operation.

The invention discloses an electric-toy electrical property testing device. Side bumpers are arranged on the left lateral side, the right lateral side and the rear respectively; an electrical property testing box is installed on the right side of a bottom plate, a tool with adjustable temperature testing points is installed on the left side of the bottom plate, a bar code reader is installed on the bottom plate, a left rib plate and a right rib plate are installed on the left side and the right side of a temperature tool bottom plate respectively, a left air cylinder and a right air cylinder are fixed to the left rib plate and the right rib plate respectively, a rod head of the left air cylinder and a rod head of the right air cylinder are oppositely arranged, a left buffer piece and a right buffer piece are arranged on the rod head of the left air cylinder and the rod head of the right air cylinder respectively, a front temperature hole plate and a right temperature hole plate are installed on the front side and the rear side of the temperature tool bottom plate respectively, round holes are evenly formed in the front temperature hole plate and the right temperature hole plate respectively, temperature pens are sleeved with the round holes respectively, and a temperature thermocouple is connected with a temperature transmitter. According to the electric-toy electrical property testing device, items, like an electric toy reduced test, a low-power-point test, a power test and a temperature rise test, which must be tested are integrated, a PLC is adopted for testing and control, and therefore errors caused by manual operation are reduced, testing can be more conveniently carried out, and time is saved; due to the adoption of an electronic load, the test precision is higher.

The invention discloses a low-temperature mechanical test method for automatically changing sample pieces. At present, in most low-temperature mechanical tests, every time a sample is changed, the door of the incubator needs to be opened to change when the room temperature is almost the same, which increases the test time. The low-temperature mechanical test device for automatically exchanging samples adopted in the present invention uses parallel grippers to grab the samples, the translation drive device realizes the expansion and contraction of the parallel grippers, the linear driver realizes the lifting of the parallel grippers, and the rotary drive device realizes the parallel grippers The rotation; the control system controls the movement of the parallel gripper, the translational drive, the linear drive and the rotary drive, as well as data transmission. Steps of the present invention: first input the size parameters of the sample into the control system, place the sample on the sample pre-cooling rack and pre-cool it together with the low-temperature test box, and when the temperature reaches the set value, execute through the control system "Load" and "Unload" actions. The invention does not need to open the low-temperature test box, that is, the sample sample can be changed automatically.

The invention relates to an automatic test instrument for an Allen test. The problems of increasing identification efficacy and reducing the ratio of false negative or false positive in test results can be effectively solved. In the automatic test instrument, a tank body is formed by hinging a lower tank body and an upper tank body with the same caliber through a hinge, the upper tank body is of an opening and closing structure by taking the hinge as a shaft, corresponding electromagnet sucking discs are respectively arranged at the front four corners of the tank body, and the front joining part of the upper tank body and the lower tank body is provided with a wrist bonding hole; the front surface of the upper tank body is provided with a button switch, an observation hole is arranged on the top surface, and a power source, an assembly comprising an air compressor and an electromagnetic valve and a light source are arranged inside the upper tank body; and an air sac is arranged at the wrist bonding hole, the air sac is communicated with the air compressor via pipelines and the electromagnetic valve, and the power source is connected with an air compressor switch, an electromagnetic switch on the left air sac pipeline, an electromagnetic switch on the right air sac pipeline, an electromagnet sucking disc closing switch and the light source via a power source switch. The automatic test instrument has convenience for carrying and use, prominent observation topic, simple structure, low cost and easiness in operation.

The invention discloses an intelligent fat-reducing treadmill and its fitness guidance method, which is characterized by comprising: a body fat rate measurement module, an exercise heart rate measurement module, a control processing module, a human-computer interaction module, a power supply module and a treadmill main body. The present invention can provide suitable fat-reducing exercise schemes for different users, so as to realize a more humanized and intelligent body-building purpose.

The invention provides a rotary hydrostatic testing machine for steel bottles of liquefied gas, which comprises a horizontally arranged disc-shaped turntable (9); a plurality of test beds (1) for testing hydraulic pressure of the steel bottles are arranged on a position of the turntable (9) close to an outer edge in the circumferential direction; and the turntable (9) is also provided with a high-pressure hydraulic pump (2) connected with the test beds (1) through water pipes, a hydraulic station (4) connected with the test beds (1) through oil pipes, a self-rotating machine (5) used for driving the turntable to rotate, and a self-sucking pump (8) connected with the test beds (1) through water pipes. The prior (8hr) 600 steel bottles per shift are improved to 2,400 steel bottles per shiftin hydrostatic tests for the steel bottles of liquefied gas. The rotary hydrostatic testing machine greatly lightens the labor intensity of operators; and the test process is more standard, and test results are more reliable.
