Abstract
The utility model relates to a fastening apparatus used in railway, highway, waterway and airway transportation, which comprises a hook (6), a connecting ring (5), a screw rod (1), a sleeve (2), a shaft pin (3), a ratchet (4), a pawl (8), a dowel (7), a steel ball (9), a spring (10), a handle (11), etc., wherein, the handle (11) is fitted over the sleeve (2); the screw rod (1), the connecting ring (5) and the hook (6) are mounted on both ends of the sleeve (2); the ratchet (4) and the pawl (8) are arranged on the inboard side of the fish-mouth shaped fork of the handle (11); the handle (11) drives the sleeve through the ratchet (4) and the pawl (8) to extend or retract the screw rod (1), thereby fastening or unfastening the articles and allowing self-locking. With high efficiency and good self-locking, etc, the utility model can save labor and can fasten and unfastening quickly.
Description
One, affiliated technical field
The utility model is a kind of transportation with the binding tightening device, and the instrument of being reinforced by the binding of fortune object in the transportation such as specifically a kind of railway, highway, boats and ships, aviation also can be used in the warehouse binding to the motion object and reinforces.
Two, background technology
At present, the domestic instrument of the fastening usefulness of binding to the transportation object, majority are that to adopt iron wire, strand rod etc. to bundle fastening, and it needs operating personal many, and binding and removal time are long, and labour intensity is big, efficient is low.Also have some effectively self-lockings of binding tightening device, easily loosening in the transportation, there is potential safety hazard.
Three, summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model provides a kind of efficient, effective self-locking fastener of self-locking of rapid operation that has, to adapt to the needs that railway, highway etc. transport high speed developments.
The technical scheme that the utility model is taked is, sets up ratchet device on the basis of steel wire fastener, promptly is made up of hook, coupling link, screw rod, sleeve, bearing pin, ratchet, ratchet, pin, steel ball, spring, handgrip etc.The middle part of sleeve is provided with pin shaft hole, and the two ends of sleeve are opposite with the hand of spiral at screw rod connection and two ends by screw thread, and screw rod connects with hook by coupling link.Handgrip is the lymphogranuloma inguinale fork at an end that connects with sleeve, lymphogranuloma inguinale fork place at handgrip is provided with sleeve hole, and the inboard root of lymphogranuloma inguinale fork is provided with spring eye, and the lymphogranuloma inguinale fork is provided with pin hole near its root, handgrip is contained in the middle part of sleeve by its sleeve hole, and can rotate on sleeve.Ratchet is fixed on the pin shaft hole place on the sleeve and pitches inboard at the lymphogranuloma inguinale of handgrip by bearing pin, ratchet by pin be contained in the inboard pin hole place of the lymphogranuloma inguinale fork of handgrip, and and ratchet engaged, spring is contained in the lymphogranuloma inguinale of handgrip and pitches in the spring eye of root, and steel ball is contained between spring and the ratchet and by spring and is pressed on the ratchet.
During use, the hook at two ends is connected with tied object by steel rope or chain, by the engagement direction of adjustment ratchet and ratchet, manipulating handgrip, by ratchet, ratchet, sleeve, screw rod is shortened or elongation, thus fastening or loose the unloading of realizing tied object.After object binding firmly, with the handgrip contrarotation, handgrip is withheld on the transport vehicle floor, must not be rotated further, thereby play the effect that the restriction sleeve rotates and have ratchet, ratchet, realize the self-locking purpose.
Because the utility model is provided with ratchet device and utilizes the rotation of transport vehicle floor restriction handgrip, so utility model has characteristics such as rapid operation, degree of tightness, efficient height, self-locking property be good fast.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, specific implementation method
As shown in the figure, the utility model is made up of screw rod 1, sleeve 2, bearing pin 3, ratchet 4, coupling link 5, hook 6, pin 7, ratchet 8, steel ball 9, spring 10, handgrip 11 etc.The middle part of sleeve 2 is provided with pin shaft hole, the two ends of sleeve 2 connect by screw thread and screw rod 1 and the hand of spiral of the screw thread at two ends opposite, promptly an end is that left-handed, the other end is dextrorotation.Screw rod 1 connects with hook 6 by coupling link 5.Handgrip 11 is a lymphogranuloma inguinale fork at an end that connects with sleeve 2, and lymphogranuloma inguinale is stuck and is provided with sleeve hole, and handgrip 11 is contained in the middle part of sleeve 2 by its sleeve hole, and ratchet 4 is fixed on the sleeve 2 by the pin shaft hole on bearing pin 3, the sleeve 2 and is inboard at handgrip 11 lymphogranuloma inguinale fork.Handgrip 11 is provided with pin hole near lymphogranuloma inguinale fork root place, and ratchet 8 is contained in lymphogranuloma inguinale fork inboard by pin 7, pin hole and meshes with ratchet 4.The lymphogranuloma inguinale fork root of handgrip 11 is provided with spring eye, and spring 10 is contained in the spring eye, and steel ball 9 is contained between spring 10 and the ratchet 8, steel ball 9 is pressed on the ratchet 8 by spring 10.
The utility model in use, the hook at two ends 6 is good with Goods binding by steel rope or chain, adjusts the engagement direction of ratchet 8 and ratchet 4, manipulating handgrip 11, by ratchet 8, ratchet 4 sleeve 2 is rotated, drive screw rod 1 and shorten or elongation, thereby tighten or pine are unloaded goods.After Goods binding was fastening, backward rotation handgrip 11 was withheld on the floor of transport vehicle handgrip 11, and restriction handgrip 11 continues rotation, utilized ratchet 4, ratchet 8 and 11 rotations of floor restriction handgrip, reached self-locking action.Therefore the utlity model has characteristics such as rapid operation, degree of tightness, efficient height, self-locking property be good fast.
