Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention.

Traditional handheld listening frock, through the mode of setting up the placing cavity in base 1 and apron 2, place monomer 4 that awaits measuring, but lack supporting monomer positioning mechanism, and the cavity structure is fixed, lead to listening frock commonality poor, in order to improve listening frock's commonality, guarantee the leakproofness of front and back chamber butt joint and the accuracy of location, make listening data accurate, design a handheld listening frock, as shown in fig. 1, including base 1, apron 2 and elastic component 3, the one end of apron 2 is connected with the one end rotation of base 1, the other end of apron 2 is connected with the other end magnetism of base 1, be equipped with the magnetic stripe of mutual absorption on the contact surface of upper die base 21 and die holder 11, elastic component 3 connects apron 2 and base 1, be equipped with upper die base 21 on the apron 2, be equipped with on the upper die base 21 and support the depression bar 22 and switch-on the pole 23, the lower surface of upper die base 21 is opened has the standing groove 12 that can hold monomer 4 that awaits measuring, be equipped with die holder 11 on the upper die base 11 and open the side and hold breach 12 and drive the die holder top and support the die holder 11 and pass through the die holder 13 and support the die holder, make the die holder 21 and support the die holder top and lean on the die holder 11 and support the die holder 13 that awaits measuring monomer that awaits measuring.

This handheld listening frock structure is light and handy, can let the tester handheld test, more make things convenient for the tester listening, it is very convenient to operate, do benefit to and improve efficiency of software testing, in addition, during the test, because apron 2 and base 1 can form magnetism to inhale the connection under the adsorption of magnetic stripe, can offset partly elasticity and support the pressure of supporting of depression bar 22, so the tester need not to use very big power just can make apron 2 and base 1 keep foldingly the state, very laborsaving. The placing grooves 12 on the upper die holder 21 and the lower die holder 11 are arranged according to the specification of the monomer 4 to be tested, when the cover plate 2 and the base 1 are folded, the upper die holder 21 and the lower die holder 11 are covered, the sealing performance and the positioning accuracy of the butt joint of the front cavity and the rear cavity can be ensured, and then the listening test is carried out through the listening ports formed in the side surfaces.

In order to ensure the stable installation of the pressing rod 22 and the conducting rod 23, the upper die base 21 is provided with a mounting hole 26 through which the pressing rod 22 and the conducting rod 23 can pass, the low-pressure rod and the conducting rod 23 are both adhered in the mounting hole 26 through glue, and the extending lengths of the pressing rod 22 and the conducting rod 23 can be adjusted according to the actual listening requirement.

When guaranteeing to advance line location to the monomer, in order to avoid causing the damage to the monomer, set up in the bottom of pressing the pole 22 and support the pressure head 27, the diameter that supports pressure head 27 is greater than the diameter that supports the depression bar 22, and the increase is supported the pressure area, can not only guarantee to support and press stability, can also avoid damaging the monomer. The conducting rod 23 is a telescopic probe which comprises an insulating shell, and a fixed conductor, a movable conductor, a connecting conductor and an elastic piece which are arranged in the insulating shell; the fixed conductor is fixed in the insulating shell, the end part of the fixed conductor is exposed out of one end of the insulating shell, and the movable conductor is movably arranged in the insulating shell, and the end part of the movable conductor is exposed out of the other end of the insulating shell; form electric connection through the connecting conductor between fixed conductor and the movable conductor, the elastic component is located between fixed conductor and the movable conductor and outwards pushes away the movable conductor to insulating casing, through the scalable of movable conductor on insulating casing, can make conductive probe when lieing in to be surveyed the object contact, carries out effectual buffering to conductive probe's pressure, prevents that rigid conductive probe from causing to collide with to being surveyed the object surface, forms good protection to being surveyed the object.

As shown in fig. 2 and 3, for realizing the activity setting of upper die base 21, make its die holder 11 relatively finely tune, set up the mounting groove 24 that the slidable set up upper die base 21 on apron 2, mounting groove 24 runs through apron 2, be equipped with in the mounting groove 24 and be used for the spacing cyclic annular step 25 of upper die base 21, make upper die base 21 arrange cyclic annular step 25 below in, after apron 2 and base 1 fold, upper die base 21 adsorbs the laminating with die holder 11 under the magnetic stripe adsorption, thereby make the monomer 4 that awaits measuring stably arrange in standing groove 12, for the fixed upper die base 21 that sets up in traditional listening frock, the upper die base 21 flexibility that the activity set up is better, can make the upper and lower die base laminate more.

As shown in fig. 4 and 5, in order to ensure the stable placement of the lower die holder 11, a mounting cavity 14 capable of accommodating the lower die holder 11 is formed in the base 1, the height of the lower die holder 11 is greater than the depth of the mounting cavity 14, and the lower die holder 11 is arranged in a protruding manner to be matched with the upper die holder 21.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
