When meeting the requirements of strength and weight, the clamp has good reliability and high stability, and has good suitability with any type of vibration or impact table.
The utility model comprises a bracket frame body structure consisting of a bottom bracket, a lateral bracket and a back bracket, wherein a bottom connecting plate is fixed on the bottom bracket, the upper part of the back bracket is connected with a back connecting plate, and a plurality of back reinforcing supports are arranged at the lower part of the back bracket; the side support is an inclined support structure connected to the bottom of the bottom support and the top of the back support, and a plurality of side reinforcing supports are arranged between the side support and the back support.
Further improved, the bottom bracket is of a square structure, the bottom connecting plate is a steel plate welded on the upper surface of the bottom bracket, a plurality of groups of threaded holes are uniformly distributed on the bottom connecting plate, and the bottom of the tested device and the bottom of the test fixture are convenient to fix.
Further improved, the bottom support, the lateral support and the back support are fixed through welding respectively, and the lateral supports are symmetrically distributed on two sides of the bottom support.
Further improved, the side reinforcing support is fixed with the side support and the back support through welding respectively, so that the stability of the test clamp is facilitated, and the strength is improved.
Further improved, the back reinforcing support below the back support is fixed with the back support through welding, so that the stability of the test fixture is facilitated, and the strength is improved.
Further improved, the back connecting plate is a steel plate, and a plurality of groups of waist-shaped holes are symmetrically distributed on the back connecting plate, so that the tested equipment is convenient to fix with the back of the test fixture.
The utility model has the beneficial effects that:
1. the device to be tested can be fast and accurately clamped and fixed, and is easy to be connected with a test table top, so that the operation of test staff is convenient.
2. When meeting the requirements of strength and weight, the clamp has good reliability and high stability, and has good suitability with any type of vibration or impact table.
