Description

A kind of anchor clamps

Technical field

The present invention relates to a kind of frock clamp, relate in particular to a kind of anchor clamps that are used for when test waveguide diplexer, clamping the waveguide diplexer.

Background technology

The debud mode that the waveguide diplexer adopts at present is: couple together with emission, reception and the antenna opening of screw with waveguide coaxial converter and waveguide diplexer, by cable testing tool is connected together with waveguide coaxial converter and test.The defective of this kind connected mode is that efficient is low, if testing tool is when having only two interfaces, also needs a cable is switched transmitting and receiving between the mouth, so just makes the threaded connector of cable bad easily, causes cable subscription rate rate height.

Summary of the invention

Purpose of the present invention in order to solve the problems referred to above that prior art exists, provides a kind of anchor clamps that are used to test the waveguide diplexer of new structure exactly.

In order to achieve the above object, the present invention has adopted following technical scheme: a kind of anchor clamps comprise base, two clamp holders, two active grabs, three rough positioning blocks and three groups of elastic supporting mechanisms; Two clamp holders are installed in the two ends of base respectively, two active grabs are installed in the outside of two clamp holders relatively, three rough positioning blocks both sides that are installed in base triangular in shape, three groups of elastic supporting mechanisms are triangular in shape to be installed on the base and to be staggered in the inboard of three rough positioning blocks, and the upper surface of three groups of elastic supporting mechanisms is in same elevation plane.

Described three groups of elastic supporting mechanism structures are identical, respectively comprise one group of correcting nail, a support spring, a supporting seat and a bolt, one group of correcting nail is fixed on the base, support spring and supporting seat are set on one group of correcting in proper order and nail on, and bolt passes base from the bottom up and links to each other with supporting seat with support spring and support spring and supporting seat are locked on the base.

The inboard of described three rough positioning blocks is respectively equipped with a contour limited step, and the height of this limited step is lower than the height of elastic supporting mechanism, the stroke when its difference in height forms test waveguide diplexer.

Also comprise three balancing springs, three balancing springs are triangular in shape to be arranged on the base and to be staggered between three groups of elastic supporting mechanisms, the upper level of balancing spring be higher than two rough positioning blocks limited step height but be not higher than the height of the upper surface of two groups of elastic supporting mechanisms.

Anchor clamps of the present invention adopt active grab formula clamp structure, and dismounting is fast, efficient height, the serviceable life that can improve cable.

Embodiment

Referring to Fig. 1, Fig. 2, anchor clamps of the present invention comprise base 1, two clamp holders 2, three 3, two active grabs of rough positioning blocks 4, three groups of elastic supporting mechanisms 5 and three balancing springs 6.Two clamp holders 2 are installed in the two ends of base 1 respectively, two active grabs 4 are installed in the outside of two clamp holders 2 relatively, three rough positioning blocks 3 both sides that are installed in base triangular in shape, be respectively equipped with a contour limited step 31 in the inboard of three rough positioning blocks 3, the height of this limited step is lower than the height of elastic supporting mechanism, the stroke when its difference in height forms test waveguide diplexer.Three groups of elastic supporting mechanisms 5 are triangular in shape to be installed on the base and to be staggered in the inboard of three rough positioning blocks, and the upper surface of three groups of elastic supporting mechanisms 5 is in same elevation plane.Three groups of elastic supporting mechanism structures are identical, respectively comprise 51, support springs of one group of correcting nail 52, a supporting seat 53 and a bolt 54, one group of correcting nail 51 is fixed on the base 1, support spring 52 and supporting seat 53 orders are set on one group of correcting nail 51, and bolt 54 passes base from the bottom up and links to each other with supporting seat with support spring and support spring and supporting seat are locked on the base.By selecting the height of bolt 54, determine that supporting seat 53 has rational precompression, when assembling, to make the height of two bolts the same, the end face that makes mounted two groups of elastic supporting mechanisms 5 is on same plane, and has identical precompression.Three balancing springs 6 are triangular in shape to be arranged on the base and to be staggered between three groups of elastic supporting mechanisms, the height of its upper surface be higher than three rough positioning blocks 3 limited step 31 height but be not higher than the height of the upper surface of three groups of elastic supporting mechanisms 5.Definite principle of balancing spring 6 height is for when active grab down presss from both sides, and can make diplexer evenly stressed, can be parallel descending under the effect of pressure.

Using method of the present invention and working mechanism can be in conjunction with Fig. 3, Fig. 4 is described as follows: earlier test cable line 7 is connected instrument and waveguide coaxial converter 8, again waveguide coaxial converter is put on the supporting seat 53 by correcting nail 51, allow active grab at the open type state, accurately navigate to anchor clamps on by rough positioning blocks 3 and correcting nail waveguide diplexer 9, make waveguide mouth 81 alignment of the waveguide mouth and the waveguide coaxial converter of waveguide diplexer, pull down simultaneously two active grabs, 4 locking fixtures again, because the height unanimity of several supporting seats, and limited step is arranged on rough positioning blocks, make descending stroke D (seeing the sign on Fig. 4) unanimity, as long as D value reasonable in design just can make waveguide coaxial converter have enough elastic force and be adjacent to the waveguide diplexer, so just can begin stable debugging, unclamp active grab taking-up waveguide diplexer after having debugged and get final product.
