Description

Technical Field

[0001] The invention relates to the technical field of chain saw suspension testing. Background Art

[0002] Chain saws are widely used all over the world. Due to their convenience, they are increasingly favored by consumers. Their increasing popularity has also become a trend in the development of chain saws. In the past few years, the export of chain saws has been growing continuously and has gradually formed a scale in the European market, one of the two largest markets in the world. However, due to the lack of complete safety testing capabilities, the export of this product has been restricted to a certain extent.

[0003] In order to facilitate the export business of domestic garden chain saw manufacturers and realize the localization of safety testing and certification, it is necessary to establish a complete testing capability for the European and American standard safety certification of the product. One of the important safety indicators, the chain saw suspension test, must meet the performance requirements of the standard test.

[0004] The existing testing equipment fixes the chain saw through an aluminum alloy frame, and then reinstalls and fixes it for each test position. This is troublesome and cannot control safety, brings inconvenience to the test, and does not improve the test efficiency.

[0005] Therefore, there is a great need for a special test equipment that is both convenient and can increase the installation speed, so that the test data obtained is also relatively stable. Furthermore, in order to reduce costs, reduce the floor space and a large number of testers, the test equipment should be as practical and occupy as little space as possible while meeting the standard requirements and safety performance. Summary of the invention

[0006] The purpose of the present invention is to solve some of the demands for chain saw suspension testing in the existing market and technology, and to provide a chain saw suspension testing device.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A chain saw suspension test device comprises a vertical plane rotating spring locating pin, a vertical plane rotating shaft, a shaft sleeve, a horizontal rotating shaft, a horizontal rotating shaft sleeve, a support rod, a horizontal plane rotating spring locating pin, a vertical plane rotating sleeve, a square shaft and a suspension sample nut.

[0009] The horizontal rotating sleeve is fixed to the top of the support rod, and the horizontal rotating shaft is arranged in the horizontal rotating sleeve; the horizontal rotating sleeve is provided with a horizontal plane rotating spring positioning pin, and the horizontal rotating shaft is provided with a positioning hole, and the size of the positioning hole is adapted to the horizontal plane rotating spring positioning pin;

[0010] The upper end of the horizontal rotating shaft is connected with a horizontal sleeve, and the sleeve is provided with a vertical surface rotating spring positioning pin;

[0011] The inner end of the vertical plane rotating shaft is arranged in the shaft sleeve, and the outer end is connected to the vertical plane rotating sleeve; four pin holes are arranged on the inner end of the vertical plane rotating shaft, and when any pin hole corresponds to the position of the vertical plane rotating spring locating pin, the vertical plane rotating spring locating pin automatically pops into the pin hole;

[0012] The square shaft is connected with the vertical surface rotating sleeve, and the suspended sample nut is connected with the square shaft.

[0013] Furthermore, the horizontal rotating sleeve is fixedly connected to the support rod via a flange and bolts.

[0014] Furthermore, the horizontal rotating shaft and the horizontal rotating shaft sleeve are clearance-matched.

[0015] Furthermore, the horizontal rotating shaft has two positioning holes with a difference of 90°. One positioning hole is used for the experimental position, and is inserted with the horizontal plane rotating spring positioning pin 7; the other positioning hole is used for convenient placement against the wall after the experiment is completed.

[0016] Furthermore, the square shaft and the suspended sample nut are respectively provided with matching square holes, which can facilitate the rotation of the suspended sample nut in four directions. Furthermore, the chain saw suspension test device also includes a locking handle for locking and fixing the position of the suspended sample nut.

[0017] Beneficial effects of the present invention:

[0018] The specialized chain saw suspension test device provided by the present invention has a sophisticated structural design, occupies a small area, is convenient and quick to install, and can reduce a large number of test personnel.

[0019] At the same time, because it is specifically tested against safety standards, the structural stability is safer and more stable than previous manual adjustments, and the test data obtained is more accurate, which improves efficiency and cost. BRIEF DESCRIPTION OF THE DRAWINGS
