2results about How to "Eliminate shear force" patented technology

The utility model discloses a bus capacitance convenient to test and anti -vibration, including capacitance body still including the capacitor shell of encapsulating capacitance body, and one side of capacitor shell is equipped with a plurality of interval arrangement's sampling needle, sampling needle is connected with capacitance body electricity, be equipped with the anti -vibration section of having elasticity on sampling needle, the utility model discloses a capacitor shell encapsulates capacitance body in, because sampling needle is provided with anti -vibration section, absorbs certain random vibration and impact load in use, eliminates more shearing force, can avoid sampling needle and customer section connect after the damage due to vibration, thereby improved the life of sampling needle. Capacitor shell still through the additional setting test slot, makes the capacitor structure can hold the test chuck in the test department position after the field, thereby can carry out the test, avoids sampling needle end damage, and setting test slot still can reduce the shell material, reduces production cost.

The invention relates to the technical field of forestry planting and ecological tending equipment, and discloses a device for assisting under-forest rattan climbing, the device comprises a bionic spine assembly, the bionic spine assembly comprises a first assembly and a plurality of second assemblies, one end of each of the first assembly and the second assemblies is connected with a target supporting wood through a top base, and the other end of each of the second assemblies is connected with a ground anchoring assembly, the first assembly is formed by connecting a plurality of first hollow cone units in an end-to-end nesting mode in series and forms a climbing center supporting body of the rattan rattan, the second assembly is formed by connecting a plurality of second hollow cone units in an end-to-end nesting mode in series, and the second assemblies are arranged around the first assembly in a circular array mode to form a cylindrical climbing channel. Through the synergistic effect of the center tensioning assembly and the ball socket matching structure, the physical contradiction between rigid supporting and flexible recycling is solved. By adjusting the axial prestress of the internal inhaul cable, the bionic spine assembly can be freely switched between a rigid columnar working state in which the bionic spine assembly bears the weight of rattan stems and a loose and soft flexible chain recovery state.
