Abstract
The utility model relates to a locking ring quick assembling locking device for quickly assembling and disassembling an extra-large tire steel ring. Two screw seat holes are formed in a locking ring; bodies of screw seats are rectangular hexahedrons; through holes are formed in the middles of the hexahedrons; fixing rods are arranged on the hexahedrons, are not contacted with the screw seat holes, and can freely rotate in the screw seat holes; a left-handed and right-handed screw is inserted into the through holes in the middles of a right-handed screw seat and a left-handed screw seat; a locking nut is arranged on the left-handed and right-handed screw; the locking ring is stretched when the left-handed and right-handed screw is rotated counterclockwise, so that the locking ring is convenient to assemble and disassemble, and the condition that installation personnel are hurt due to bounce is avoided; the locking ring is locked when the left-handed and right-handed screw is rotated clockwise, so that the locking ring can be in tight fit with a groove ring, the problem that the locking ring formed by splicing two half parts previously cannot be tightened is solved, the screw seats rotate with the rotation of the left-handed and right-handed screw, and the left-handed and right-handed screw is on the same straight line; and the device is suitable for the conventional 51'-63' rims and has good popularization benefits.
Description
Technical field:
The utility model relates to a kind of retainer accessory of motor tire steel ring, particularly a kind of retainer fast-assembling latching device that is used for fast assembling-disassembling over size tyre steel ring.
Background technology:
In the exploitation and engineering construction of glory-hole, the heavy construction car is widely used because of its more load carrying ability, and the tire of this type of full size vehicle is also very huge; General diameter is 3.2m-4.2m, is used for fixing the heavily about 60kg of retainer of tire, is processed by spring steel; During each dismounting, need many people rely on manpower that retainer is opened, not only waste time and energy; The dismounting difficulty, and careless slightly, and the elastic force that retainer is huge also can cause injury to personnel.In order to address this problem, the retainer of the model that has is that two halves are spliced, and during installation, with screw two halves are coupled together, but after this retainer installation, because screw retention is arranged, retainer can't tighten up.
The utility model content:
The purpose of the utility model is to provide a kind of retainer fast-assembling latching device that is used for full size vehicle tire fast assembling-disassembling.
To achieve these goals, the utility model proposes following technical scheme realization:
Retainer fast-assembling latching device, mainly comprise retainer, screw bolt seat hole, about revolve screw rod, right handed screw seat, left-handed screw seat, jam nut, fix screw, packing ring, screw, fixed link; It is characterized in that: retainer is provided with an opening, and top, opening two ends respectively has a screw bolt seat hole, and right handed screw seat and left-handed screw seat pedestal are a rectangular hexahedron; The hexahedron middle part has through hole, connects the left and right sides, and hexahedron is provided with fixed link; Have screw on the fixed link; Right handed screw seat and left-handed screw seat insert the screw bolt seat hole through fixed link respectively, and fix screw and packing ring are installed on the screw, and fixed link is vertically fixed in the screw bolt seat hole; And fixed link does not contact with the screw bolt seat hole; Fixed link can freely rotate in the screw bolt seat hole, about revolve screw rod and be placed through in the through hole of right handed screw seat and left-handed screw seat middle part, revolve about between right handed screw seat and left-handed screw seat jam nut be housed on the screw rod.
The utility model has the advantages that: when the needs retainer opens, revolve screw rod about left-hand revolution, right handed screw seat and left-handed screw seat are respectively to two side shiftings; The drive retainer opens; Need not to use very big strength just can reach the effect of expansion retainer, be convenient to dismounting, because retainer is strutted by screw bolt seat; The bounce of retainer is born by screw bolt seat, and the situation of having avoided installation personnel to receive the bounce injury takes place; When the needs locking retainer, revolve screw rod about clickwise, retainer tightens up under the drive of right handed screw seat and left-handed screw seat, and retainer can be closely cooperated with the groove circle, has solved the problem that retainer that two halves in the past are spliced can't tighten up; Retainer open or the locking process in; The path of motion of right handed screw seat and left-handed screw seat is arc; Do not contact between fixed link and screw bolt seat hole; Can make right handed screw seat and left-handed screw seat along with about revolve the rotation of screw rod and rotate, revolve screw rod about assurance and can make its normal operation in a straight line.
The utility model has solved the difficulty of engineering truck retainer dismounting in the past with simple structure, and the problem that retainer can't tighten up is applicable to existing 51 " 63 " wheel rim, has the excellent popularization benefit.

The specific embodiment:
As shown in the figure, retainer fast-assembling latching device, mainly comprise retainer 1, screw bolt seat hole 2, about revolve screw rod 3, right handed screw seat 4, left-handed screw seat 5, jam nut 6, fix screw 7, packing ring 8, screw 9, fixed link 10; Retainer 1 is provided with an opening, and top, opening two ends respectively has a screw bolt seat hole 2, and right handed screw seat 4 is a rectangular hexahedron with left-handed screw seat 5 pedestals; The hexahedron middle part has through hole, connects the left and right sides, and hexahedron is provided with fixed link 10; Have screw 9 on the fixed link 10; Right handed screw seat 4 inserts screw bolt seat hole 2 through fixed link 10 respectively with left-handed screw seat 5, and fix screw 7 is installed on the screw 9 with packing ring 8, and fixed link 10 is vertically fixed in the screw bolt seat hole 2; And fixed link 10 does not contact with screw bolt seat hole 2; Make fixed link 10 in screw bolt seat hole 2, freely to rotate, about revolve screw rod 3 and be placed through in right handed screw seat 4 and the left-handed screw seat 5 middle part through holes, revolve about 5 of right handed screw seat 4 and left-handed screw seats jam nut 6 be housed on the screw rod 3.
With reference to Fig. 2, Fig. 6, when needs retainer 1 opens, revolve screw rod 3 about left-hand revolution; Right handed screw seat 4 and left-handed screw seat 5 drive retainer 1 and open respectively to two side shiftings, need not to use very big strength just can reach the effect of expansion retainer 1; Be convenient to dismounting; Because retainer 1 is strutted by screw bolt seat 4,5, the bounce of retainer 1 is born by screw bolt seat 4,5, and the situation of having avoided installation personnel to receive the bounce injury takes place; When needs are locked 1 retainer, revolve screw rod 3 about clickwise, retainer 1 tightens up under the drive of right handed screw seat 4 and left-handed screw seat 5, retainer 1 can be closely cooperated with the groove circle, has solved the problem that retainer that two halves in the past are spliced can't tighten up; Retainer 1 open or the locking process in; The path of motion of right handed screw seat 4 and left-handed screw seat 5 is arcs; Fixed link 10 does not contact with 2 in screw bolt seat hole; Can make right handed screw seat 4 and left-handed screw seat 5 along with about revolve the rotation of screw rod 3 and rotate, revolve screw rod 3 about assurance and can make its normal operation in a straight line.This device is applicable to existing 51 " 63 " wheel rim, has the excellent popularization benefit.
