Description
Technical field：
The utility model is related to a kind of pcb board welding fixtures.
Background technology：
Pcb board Chinese is printed circuit board, is the supporter of electronic component, is that electronic component is electrically connected
Carrier.Pcb board is susceptible to shaking in welding electronic component, therefore in welding process, needs to fix pcb board.It is existing
Pcb board fixed form be generally pcb board is fixed on welding bench by fixture, the contact between fixture and pcb board
Area is big, and fixture is in fixed pcb board, can press from both sides the circuit on pcb board bad, damages the structure of pcb board, influences pcb board
Using effect.
Utility model content：
The utility model is to provide a kind of pcb board welding fixture to solve the above-mentioned problems of the prior art.
Technical solution used by the utility model has：A kind of pcb board welding fixture, including bottom plate, upright bar, spring, pressure
Plate, guide rod, limiting plate, upper trip bolt and lower trip bolt, two upright bars are respectively perpendicular the left and right sides for being fixed on bottom plate,
Limiting plate is fixed in upright bar, and spring and pressing plate are sheathed in upright bar, and the upper end of spring contacts on limiting plate, and lower end is supported
It touches on pressing plate, guide rod is arranged on limiting plate, and the bottom end of guide rod is fixedly connected with the pressing plate；Several upper fastening screw threads connect
It is connected on pressing plate, several lower trip bolts are threaded on bottom plate.
Further, it is fixedly connected with rectangular slab on the pressing plate, several first threaded holes is equipped on rectangular slab.
Further, the bottom plate is equipped with several second threaded holes, is coaxially provided with below each second threaded hole
One unthreaded hole, the aperture of unthreaded hole are more than the aperture of the second threaded hole.
Further, the bottom end of the lower trip bolt is equipped with positive stop lug boss, which is adapted with unthreaded hole.
The utility model has the advantages that：
Upper trip bolt and lower trip bolt in the utility model fix pcb board, and upper trip bolt and lower fastening
Screw contradicts on the useless edge of pcb board, avoids the circuit on damage pcb board, using effect is good, and applicability is wide.
Description of the drawings：
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Fig. 3 is the partial enlarged view of the utility model.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 to Fig. 3, a kind of pcb board welding fixture of the utility model, including bottom plate 11, upright bar 12, spring 13, pressing plate
21, guide rod 22, limiting plate 23, upper trip bolt 31 and lower trip bolt 32, two upright bars 12, which are respectively perpendicular, is fixed on bottom plate 11
The left and right sides, limiting plate 23 are fixed in upright bar 12, and spring 13 and pressing plate 21 are sheathed in upright bar 12, and the upper end of spring 13
It contacts on limiting plate 23, lower end contacts on pressing plate 21.Guide rod 22 is arranged on limiting plate 23, and the bottom end of guide rod 22 and pressure
Plate 21 is fixedly connected.Several upper trip bolts 31 are threaded on pressing plate 21, and several lower trip bolts 32 are threaded in bottom
On plate 11.
It is fixedly connected with rectangular slab 210 on pressing plate 21, several first threaded holes 211 are equipped on rectangular slab 210, tightens
Gu screw 31 is threaded in the first threaded hole 211.
It is equipped with several second threaded holes 112 on bottom plate 11, one is coaxially provided in the lower section of each second threaded hole 112
Unthreaded hole 113, the aperture of unthreaded hole 113 are more than the aperture of the second threaded hole 112.
It is equipped with positive stop lug boss in the bottom end of lower trip bolt 32, which is adapted with unthreaded hole 113.Positive stop lug boss and
Unthreaded hole 113 is used cooperatively, and can be limited lower trip bolt 32 and be rotated depth.
In use, according to the useless edge on different model pcb board lower face, at least four are screwed at the often end of bottom plate 11
Pcb board, is then placed on lower trip bolt 32 by a lower trip bolt 32, and lower trip bolt 32 is supported on the useless of pcb board
On edge, the circuit on damage pcb board is avoided.Then according to the useless marginal position on pcb board upper surface, in rectangular slab 210
Trip bolt 31 on upper screw-in, upper trip bolt 31 contradict the circuit pack avoided on pcb board upper surface and contradict in pcb board
On useless edge.
Upper trip bolt 31 and lower trip bolt 32 in the utility model fix pcb board, and 31 He of upper trip bolt
Lower trip bolt 32 contradicts on the useless edge of pcb board, avoids the circuit on damage pcb board, using effect is good, applicability
Extensively.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
