The device can conveniently detect the counter force generated when the sealing rubber strip on the protective equipment in the protective engineering is compressed, and has the characteristics of light weight, portability, light weight, easy processing, convenient use and maintenance, and low manufacturing and maintenance cost.

In the measuring process of the patent, a spring dynamometer (or a spring dynamometer) is required to hook a notch at one end of a lever, the lever is lifted upwards with force, the reading on a connecting column is read, and the numerical difference of the scales on the connecting column before and after the force is applied is the compression amount of the sealing rubber strip to be detected; and reading the spring force measuring device, and obtaining the compression counter force of the sealing rubber strip to be detected through the reading of the spring force measuring device. The lever is pulled by a spring force-measuring device to change the amount of compression, which is easily unstable and cannot apply a specific amount of compression to the bead to be tested at a fast speed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a joint strip compression reaction tester to solve the problem that the volume of compression of the joint strip who detects the detection is not convenient for control.

In order to achieve the above object, the basic scheme of the present invention is as follows:

the utility model provides a joint strip compression reaction tester, includes body frame, clamp plate, pressure sensor, lead screw, scale strip and standing groove, the body frame includes diaphragm and lateral wall, the both sides at the diaphragm are fixed to the lateral wall, be equipped with the screw hole on the diaphragm, lead screw threaded connection is in the screw hole, the clamp plate rotates the bottom of connecting at the lead screw, the clamp plate is located between two lateral walls, pressure sensor fixes the lower terminal surface at the clamp plate, scale strip vertical fixation is at the clamp plate up end, just be equipped with the opening that supplies the scale strip to pass on the diaphragm, the standing groove is placed between two lateral walls.

Further, the placing groove is connected between the two side walls in a sliding mode.

Furthermore, a turntable is fixed on the screw rod.

Further, the two side walls are provided with lower sliding grooves on the inner sides, the placing groove and the two sliding grooves can slide relatively, and the inner end face of the placing groove and the inner wall of the side wall are on the same plane.

Further, the screw rod is rotatably connected with the pressing plate through a bearing.

The beneficial effect of this scheme: (1) this scheme lead screw threaded connection moves down through rotating the lead screw and driving the clamp plate on the diaphragm, and the distance that the control clamp plate of being convenient for moved down is even in controlling the compressive capacity to the joint strip who waits to detect, and pressure sensor can detect the counter-force after the joint strip compression.

(2) This scheme is equipped with the scale strip, through the observation to the scale strip, can audio-visually obtain the joint strip's that detects the compression volume.

(3) In the scheme, the placing groove is connected between the two side walls in a sliding manner, so that the placing groove can be conveniently slid out, the sealing rubber strip to be detected is placed in the placing groove, and then the placing groove is slid in, so that the sealing rubber strip to be detected is positioned right below the pressing plate; and the inner end surface of the placing groove and the inner wall of the side wall are on the same plane, so that the pressing plate can move downwards smoothly, and the situation that the placing groove blocks the pressing plate to move downwards is effectively avoided.
