Also setting up two threaded grooves on described seat body, described threaded Slot shaping is on the two ends of seat body edge
The length direction seat body extends.
The beneficial effects of the utility model are: the quiet bearing of described handcart arranges cursor fixed installation hole portion, and by it
In two fixed installation holes centrally disposed one-tenth be positioned on the center line of seat body vertical direction, two other fixed installation hole in
The heart is arranged to be positioned on the center line of seat body horizontal direction, and the center line of seat body vertical direction intersects shape with the center line of horizontal direction
Becoming a location intersection point, the center in described four fixed installation holes is equally spaced to be distributed in position the intersection point circumference as the center of circle
On, by described stationary distribution cursor fixed installation hole both sides, so, when the quiet bearing of described handcart in use, close a floodgate
Cursor can be stable be arranged in described cursor fixed installation portion, it is not necessary to threaded can realize circular-rotation limit
Position, convenient installation, the quiet bearing of described handcart facilitates stamping-out molding, and buckling deformation will not occur after life-time service, improves vacuum and breaks
The accuracy that road device connects, will not cause interference to combined floodgate, improves the service life of handcart.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the quiet bearing of handcart described in the utility model.
Accompanying drawing 2 is the sectional view in A-A direction in Fig. 1.
Detailed description of the invention
It show the quiet bearing of handcart provided by the utility model, including a seat body 1, described seat refering to accompanying drawing 1,2
Being provided with cursor fixed installation hole portion 2, the hole 3 that is located by connecting, upper steel bushing fixing hole 4 on body, described cursor fixedly mounts
Hole portion 2 includes four fixed installation holes 5, and described fixed installation hole 5, the hole 3 that is located by connecting, upper steel bushing fixing hole 4 are each along seat originally
The thickness direction of body 1 runs through setting, and two of which fixed installation hole 5 is centrally located on the center line of seat body 1 vertical direction, separately
Outer two fixed installation holes 5 are centrally located on the center line of seat body 1 horizontal direction, the center line of seat body 1 vertical direction and water
Square to center line be crossed to form a location intersection point 6, the center in described four fixed installation holes 5 is equally spaced to be distributed in fixed
Position intersection point 6 is on the circumference in the center of circle, and described upper steel bushing fixing hole 4 fixedly mounts hole in two-by-two one group of symmetrical cursor that is distributed in
