Abstract
The utility model provides a thread lever-type locking device, wherein two hand wheel transmission shafts are arranged inside and outside a cabin; a driver and a force-assistant spring are arranged on the transmission shafts; the driver is connected with a lever through a short pin shaft and an universal joint; the lever takes the long pin shaft on a hinge base as a rotating centre to rotate under the effect of the universal joint; and the transmission shaft is fixed through a fixing frame, on which a limiting body is arranged. The lever is lifted in the utility model through rotating the transmission shaft with T-shaped threads; and enough pressure is applied to a sealing device through the lever to reach sealing demands. The production efficiency is improved through using the utility model; and the reliability of the product is improved so that the batch production is convenient. The thread lever-type locking device is properly used on pressure resistant sealing cabin doors as a sealing locking device.
Description
Technical field
What the utility model proposed is the fastening apparatus that is used for pressure-resistant seal hatch door on boats and ships and the mine, the device of screw thread lever locking specifically.
Technical background
At present, mostly the pressure-resistant seal cabin door locking mode of each enterprise production is the locking of wedge surface formula, relies on gear transmission torque; Reaching sealing effectiveness must carry out scraping to each wedge surface, long in time limit, and requires locking torque big; Make difficult and complicated, require technical level high.
Summary of the invention
In order to overcome the shortcoming of existing ship cabin door locking device, the utility model provides screw thread lever locking device.This locking device solves the technical problem of pressure-resistant seal hatch door locking through lever locking hatch door.
The scheme that the utility model technical solution problem is adopted is:
Between inside and outside two handwheels, connect through power transmission shaft; Driver and power assistant spring are housed on the power transmission shaft, and driver is connected with lever through universal joint, and the lever other end and hinge seat are fixed; The axle of having strong market potential interts on the lever that is passed through on the hinge seat, and the fixed mount of fixed conveyor axle is provided with limit body.
The utility model promotes lever through having the power transmission shaft rotation of T type screw thread, utilizes lever that sealing device is applied enough pressure again, reaches seal request.The application of the utility model in the sealing of cabin hatch door can be enhanced productivity, and improves reliability of products, and is convenient to produce in batches.Suit to be applied on the withstand voltage hatch door as a kind of sealing-locking device.
Description of drawings
Fig. 1 is the utility model sectional view
Fig. 2 is the utility model left view
Among the figure, 1. lever, 2. universal joint, 3. driver, 4. short pin shaft, 5. power assistant spring, 6. power transmission shaft, 7. limit body, 8. fixed mount, 9. handwheel, 10. hinge seat, 11. axles of having strong market potential.
The specific embodiment
Shown in figure, connect two handwheels 9 in inside and outside, cabin cabin through power transmission shaft 6, power transmission shaft is threaded through T shape with driver 3; Realize that driver rises, descends, driver is connected lever 1 through universal joint 2 with short pin shaft 4, and lever is that rotate at the center with the axle 11 of having strong market potential on the hinge seat 10; Fixed mount 8 fixed conveyor axles one end, fixed mount is provided with limit body 7, and power assistant spring 5 is fixed on the power transmission shaft; One end is connected with limit body, and the other end is connected on the driver 3, plays the effect of power-assisted.
The use of the utility model
Hatch door is closed back dextrorotation handwheel 9 drive power transmission shafts 6 and is rotated in the forward; Under the effect of T type screw thread, driver 3 rises, and under the effect of universal joint 2, drives lever 1 one ends and rises; The other end serves as that the revolution center of circle descends with the axle 11 of having strong market potential on the hinge seat 10; Compress the sealing flange face, thereby weather strip is produced pressure, reach the effect of sealing.
Reverse rotation handwheel when opened door, lever have an opposite motion process.Transmission device drop to when bottom can with universal joint reverse rotation together, under the effect of universal joint and power assistant spring, lever is retracted into assigned address, but opened door has at this moment been accomplished whole hatch door and has been locked process.
