Head nut.
The characteristics of the utility model, also resides in：
Bridge plate loading plate is arranged in support housing, and support housing is joined end to end the cuboid surrounded by four pieces of metallic plates
Shape, and be connected by screw between adjoining two pieces of metallic plates, two pieces longer of metallic plate bottom is provided with inside boss.
Bridge plate loading plate lower surface indicates scale along the length direction of groove.
Groove is in T shape.
Two level meter fixed plates are with bridge plate loading plate with being bolted；Two spiral shells are offered on bridge plate loading plate
Croze, two bolt slots are located at the both sides of groove, two nuts coordinated with bolt are provided with two bolt slots respectively.
The beneficial effects of the utility model are：
(1) adjustable bridge plates for measurement of the present utility model, bridge plate by side with that by two-point contact, can be improved section during use
Precision away from method measurement linearity；
(2) adjustable bridge plates for measurement of the present utility model, simple in construction, contact head is ball nut, if during use
There is abrasion easily to change；
(3) adjustable bridge plates for measurement measurement pitch of the present utility model is variable, can meet the measurement of different range；

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Adjustable bridge plates for measurement of the present utility model, as shown in Figure 1, Figure 2 and Figure 3, including bridge plate loading plate 4, bridge plate is held
It is provided with T-shaped groove 2 on support plate 4, two level meter fixed plates 6, and two is connected with by bolt 8 on bridge plate loading plate 4
Level meter fixed plate 6 is respectively positioned on the top of groove 2, and two detection hook bolts 3, and two detection hook bolts 3 are provided with groove 2
Both pass through groove 2 and be equipped with ball nut 7, the bolt slot of two, two bolt slots point are also provided with the bridge plate loading plate 4
Not Wei Yu groove 2 both sides, it is each in two bolt slots that two nuts with the cooperation of bolt 8 are set.
As shown in figures 1 and 3, bridge plate loading plate 4 is arranged in support housing 1, and support housing 1 is by four pieces of metallic plate head and the tail
Connect and surround rectangular-shape, and fixed between adjoining metallic plate by screw, two pieces longer of metallic plate bottom is respectively provided with
There is inside boss 5.
As shown in figure 5, length direction of the bottom surface of bridge plate loading plate 4 along groove 2 indicates scale.
The adjustable bridge plates for measurement of the utility model, contacted, realized with touched face by setting ball nut 7 to be used as support
The two-point contact of bridge plate and tested surface, improve the precision of intercept method measurement linearity；Two detection hook bolts 3 and its arranging
When ball nut 7 does not fasten, detecting hook bolt 3 and ball nut 7 can move along groove 2, realize the adjustable of span, meet
The measurement of different range, the scale of the bottom of bridge plate loading plate 4 can assist to adjust span；Between ball nut 7 and detection hook bolt 3
Using threaded connection, if ball nut 7 has abrasion to change；The nut for detecting hook bolt 4 can be placed in logical by T-shaped groove 2
The top of groove 2, so as to which the installation not to level meter fixed plate 6 has an impact；Bolt 8 and the nut being arranged in bolt slot connect
