Abstract
A kind of self-locking board holder, including hoisting frame, hoisting frame is rectangular frame structure, the lower flat bar of hoisting frame is equipped with notch, the lower flat bar of notch one end is connected with eccentric wheel by axis pin, and the other end is equipped with screw rod contiguous block, and screw rod contiguous block is equipped with horizontal threaded hole, screw rod is connected through threaded hole with screw rod contiguous block, and screw rod is equipped with collet close to one end of eccentric wheel.By using said structure, by using suit threaded rod, structure is simplified, and improve adaptability of the device to different-thickness plate；At the same time by eccentric wheel, realize and fastening is effectively clamped to plate, it is bigger to the chucking power of plate when panel weight is bigger, the lifting stability of big weight plate has further been effectively ensured.
Description
Technical field
Hoisting board equipment is the utility model is related to, particularly a kind of self-locking board holder.
Background technology
In engineering in practice, there are the transport and handling of the various thickness plates of all kinds, needed in its cargo handling process pair
Plate carries out reliable retention, but due to the material type by plate（Such as glass, steel, timber）, size, thickness limitation,
Ongoing clamp device adaptability and reliability can not be met the requirements.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of symmetrical plate holder dress with eccentric wheel
Put, efficient with clamping, chucking power is big, and to board dimension specification, the wide adaptability of type is easy to operate, lower-cost
Feature.
In order to solve the above technical problems, technical solution is used by the utility model：A kind of self-locking plate clamping dress
Put, including hoisting frame, hoisting frame are rectangular frame structure, the lower flat bar of hoisting frame is equipped with notch, notch one end
Under flat bar eccentric wheel is connected with by axis pin, the other end is equipped with screw rod contiguous block, and screw rod contiguous block is equipped with horizontal spiral shell
Pit, screw rod are connected through threaded hole with screw rod contiguous block, and screw rod is equipped with collet close to one end of eccentric wheel.
In preferable scheme, the axis pin between the lower flat bar and eccentric wheel is positioned close to the lower flat bar one of screw rod
End, and length of the axis pin to lower flat bar close to screw rod one end is less than eccentric radius.
In preferable scheme, handwheel is equipped with by flat key on the one end of the screw rod away from eccentric wheel, handwheel passes through spiral shell
Mother is fixed on screw rod.
In preferable scheme, the eccentric wheel is equipped with spacer pin, when the center of circle and the axis pin of eccentric wheel are located at same water
When in plane, the upper plane contact of spacer pin and lower flat bar.
In preferable scheme, the collet is equipped with skid resistant course on one end close to eccentric wheel.
A kind of self-locking board holder that the utility model is provided, by using said structure, has below beneficial to effect
Fruit：
（1）By using suit threaded rod, structure is simplified, and improve adaptability of the device to different-thickness plate；
（2）By eccentric wheel, realize and fastening is effectively clamped to plate, when panel weight is bigger, the clamping to plate
Power is bigger, and the lifting stability of big weight plate has further been effectively ensured.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the overall structure diagram of the utility model.
In figure：Hoisting frame 1, spacer pin 2, eccentric wheel 3, axis pin 4, plate 5, collet 6, screw rod 7, handwheel 8, nut 9, puts down
Key 10, screw rod contiguous block 11, threaded hole 12, lower flat bar 101.
Embodiment
In Fig. 1, a kind of self-locking board holder, including hoisting frame 1, it is characterized in that：Hoisting frame 1 is rectangle
Frame structure, the lower flat bar 101 of hoisting frame 1 are equipped with notch, and the lower flat bar 101 of notch one end is connected with by axis pin 4
Eccentric wheel 3, the other end are equipped with screw rod contiguous block 11, and screw rod contiguous block 11 is equipped with horizontal threaded hole 12, and screw rod 7 passes through spiral shell
Pit 12 is connected with screw rod contiguous block 11, and screw rod 7 is equipped with collet 6 close to one end of eccentric wheel 3.
In preferable scheme, the axis pin 4 between the lower flat bar 101 and eccentric wheel 3 is positioned close to the lower flat of screw rod 7
101 one end of bar, and axis pin 4 is less than 3 radius of eccentric wheel to length of the lower flat bar 101 close to 7 one end of screw rod.
In preferable scheme, handwheel 8, handwheel 8 are equipped with by flat key 10 on described one end of screw rod 7 away from eccentric wheel 3
It is fixed on by nut 9 on screw rod 7.
In preferable scheme, the eccentric wheel 3 is equipped with spacer pin 2, when the center of circle and the axis pin 4 of eccentric wheel 3 are located at together
When on one horizontal plane, the upper plane contact of spacer pin 2 and lower flat bar 101.
In preferable scheme, the collet 6 is equipped with skid resistant course on one end close to eccentric wheel 3.
The operation principle and operating method of the present apparatus are as follows：
Plate 5 is placed longitudinally, the present apparatus is then put into position to be held by the top of plate 5, rotation eccentric wheel 3 makes limit
Position pin 2 abuts in plane on lower flat bar 101（As shown in Figure 1）, then rotating handwheel 8 makes collet 6 be moved to collet 6 to plate 5
Contacted with plate 5, can slightly exert oneself to carry out pretension, if repeating to clamp and the pretension slightly of loose unloading same specification thickness plate 5.
Carry out after clamping in advance, carry hoisting frame 1 upwards, since the frictional force between eccentric wheel 3 and plate 5 acts on,
So that eccentric wheel 3 deflects clockwise, and then clamp plate and form self-locking.
It is slight firmly to push down on hoisting frame under 5 longitudinal state of plate, hoisting frame 1 is occurred relative to plate 5
To bottom offset, eccentric wheel 3 returns to initial position naturally, and clamping is unclamped.
