Abstract
The utility model belongs to the technical field of mechanical pressing of screen meshes, and discloses a detachable gear rack pressing device.A pressing block is clamped on the upper side of the right end of a wedge-shaped rack, teeth are arranged on the upper side of the left end of the wedge-shaped rack, and the upper ends of the teeth are meshed with gears; an adjusting nut is welded in the middle of the outer side of the gear, and the gear is a detachable gear; an inclined plane is arranged on the upper side of the right end of the wedge-shaped rack, and limiting blocks are welded at two ends of the inclined plane. The utility model discloses a cooperation of movable gear and rack utilizes the spanner to rotate adjusting nut, makes under the linear motion of the roll rack of ordering about the area inclination of gear to the supporting shoe, the easier supporting shoe that slides in of wedge rack realizes compressing tightly, and is more quick and laborsaving in the aspect of dismantling the wedge rack, realizes compressing tightly and dismantling that the wedge rack is easier, the convenient operation of realization personnel's operation.
Description
Technical Field
The utility model belongs to the technical field of the screen cloth machinery compresses tightly, especially, relate to a can dismantle rack and pinion closing device.
Background
Currently, the closest prior art in the industry:
when the screen mesh of the vibrating screen on the solid control equipment is tightly pressed, the screen mesh is easy to fall off under the vibrating condition of the vibrating screen. The existing solution is that the wedge block is directly adopted for compressing, the wedge block with inclination is adopted, a supporting frame is arranged on the wedge block, and the wedge block with inclination is knocked into the supporting block to realize the compressing of the screen of the vibrating screen. However, the wedge block has large friction force when the supporting block is knocked in, so that knocking in is laborious, and the wedge block needs to overcome larger resistance to realize disassembly when the wedge block is disassembled.
In summary, the problems of the prior art are as follows:
when the wedge blocks are used for compressing the screen of the vibrating screen, the friction force of the wedge blocks is large when the supporting blocks are knocked in, the knocking-in is hard, and the disassembly needs to be realized by overcoming larger resistance during disassembly.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a can dismantle rack and pinion closing device.
The utility model discloses a realize like this, a can dismantle rack and pinion closing device is provided with:
a wedge-shaped rack;
a fastening block is clamped on the upper side of the right end of the wedge-shaped rack, teeth are arranged on the upper side of the left end of the wedge-shaped rack, the upper ends of the teeth are meshed with a gear, and a central hole of the gear is matched with and fixedly arranged through a fixed shaft;
and an adjusting bolt is welded in the middle of the outer side of the gear.
The utility model discloses a cooperation of movable gear and rack utilizes the spanner to rotate adjusting nut, makes under the linear motion of the roll rack of ordering about the area inclination of gear to the supporting shoe, the easier supporting shoe that slides in of wedge rack realizes compressing tightly, and is more quick and laborsaving in the aspect of dismantling the wedge rack, realizes compressing tightly and dismantling that the wedge rack is easier, the convenient operation of realization personnel's operation.
Further, the gear is detachable, and the gear centre bore passes through the fixed axle cooperation and realizes only permitting the rotational motion, connects through the plum blossom ratchet spanner and can dismantle the operation.
The utility model discloses a can dismantle the gear and make the gear use as an instrument, not as closing device, better protection gear makes its life longer.
Furthermore, an inclined plane is arranged on the upper side of the right end of the wedge-shaped rack, and limiting blocks are welded at two ends of the inclined plane.
Drawings
Fig. 1 is a schematic structural view of a detachable rack and pinion hold-down device provided in an embodiment of the present invention;
in the figure: 1. a wedge-shaped rack; 2. a fastening block; 3. a gear; 4. adjusting the screw cap; 5. and (4) screening.
Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the embodiment of the present invention provides a detachable rack and pinion hold-down device, including: the device comprises a wedge-shaped rack 1, a fastening block 2, a gear 3 and an adjusting nut 4.
A fastening block 2 is clamped on the upper side of the right end of the wedge-shaped rack 1, sawteeth are arranged on the upper side of the left end of the wedge-shaped rack 1, the upper ends of the sawteeth are in meshed connection with a gear 3, and a central hole of the gear 3 is matched with the fixed shaft and is fixedly arranged through the fixed shaft; an adjusting nut 4 is welded in the middle of the outer side of the gear 3.
Preferably, the gear 3 is a detachable gear. The central hole of the gear is matched with a fixed shaft to realize only rotation movement, and the gear is connected with a double offset ring ratchet wrench to be disassembled.
As preferred, the inclined plane has been seted up to 1 right-hand member upside of wedge rack, and the welding of inclined plane both ends has the stopper.
The utility model discloses a theory of operation is:
the utility model discloses when using, stretch into the less right-hand member of wedge rack 1 height between screen cloth 5 and the upper end supporting shoe, utilize the spanner to rotate the adjusting nut 4 in the gear 3 outside, the roll of gear 3 orders about and takes wedge rack 1 right-hand member linear motion to the supporting shoe under, the realization compresses tightly, when dismantling wedge rack 1, can realize dismantling wedge rack 1 fast to opposite direction rotation adjusting nut 4 through the spanner. Wherein, can dismantle the gear and make the gear use as a instrument, do not regard as closing device, better protection gear makes its life longer.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
