For solving and meet the needs of Tunnel Engineering, need to provide a kind of special locking sleeve.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of tube and couple scaffold special locking sleeve, and during to prevent fastening bolt, Hexagonal jacket drops.
The utility model technical problem is solved by following proposal: the special locking sleeve of a kind of tube and couple scaffold, be clamped in the head of ratchet spanner by spring and steel ball, be provided with ratchet side's tenon at the head of ratchet wrench, sleeve is clamped on ratchet side's tenon through a clamp ring by steel ball, wherein
Be provided with a back-up ring above described sleeve, clamp ring is enclosed within upper cartridge, is supported spacing by back-up ring lower edge;
Described clamp ring internal diameter pars intermedia establishes a bulge loop or pair of flanges, groove is formed above clamp ring internal projecting ring or pair of flanges, along the one end supporting spring under bulge loop or flange, the other end of spring is supported above sleeve, makes clamp ring press down displacement along sleeve outer wall and to be resetted by spring-return power;
Described steel ball is located at the top of spring, and by sleeve clamping on ratchet side's tenon, during zip collar instantly, steel ball drops on groove, conveniently takes off or exchanges sleeve.
The locking of the utility model steel ball is the Action of Gravity Field according to lock sleeve inwall and steel ball, coupling mechanism force will be caused to decline because of spring fatigue.Structure is reliable.
On such scheme basis, sleeve is at least provided with a pair symmetrical circular hole, corresponding is also provided with symmetrical ratchet side mortise on described ratchet side tenon, and steel ball number is not more than circular hole and ratchet side's mortise quantity, and steel ball embeds ratchet side's mortise internal locking sleeve from circular hole; During zip collar instantly, steel ball falls in groove, and sleeve unlocks, and can take off or exchange sleeve; After ratchet side's tenon on jacket casing, unclamp clamp ring, make it reset under the effect of spring-return power, and steel ball drops down onto flange place under gravity and headed in corresponding circular hole and ratchet side's mortise, locking bushing.Sleeve can not come off and rotate on ratchet side's tenon.
Superiority of the present utility model is: locking mechanism adopts the respective outer side edges of clamp ring and steel ball, and sleeve can not Automatic-falling after fixing, and improves the security of construction.

Detailed description of the invention
As shown in accompanying drawing 2 the utility model structural representation:
The special locking sleeve of a kind of tube and couple scaffold of the utility model, the head of ratchet spanner is clamped in by spring and steel ball, feature is: described ratchet wrench is the ratchet wrench 10 of band side's tenon, namely ratchet side's tenon 1 is provided with at the head of ratchet wrench, sleeve 3 is clamped on ratchet side's tenon 1 through a clamp ring 5 by steel ball, wherein
Be provided with a back-up ring 2 above described sleeve 3, clamp ring 5 is enclosed within sleeve 3 top, is supported spacing by back-up ring 2 lower edge;
Described clamp ring 5 internal diameter pars intermedia establishes a bulge loop 51(also can be flange), groove 52 is formed above clamp ring 5 internal projecting ring 51, one end of spring 6 is supported on bulge loop 51 times edges, the other end of spring 6 is supported in sleeve 3 upper stage portion, till making clamp ring 5 can press down and be moved to spring compression along sleeve 3, unclamp and reset in spring-return power;
Described steel ball 4 is located at the top of spring 6, is clamped in by sleeve 3 on ratchet side's tenon 1, and during zip collar 5 instantly, steel ball 4 drops on groove 52 place, between sleeve 3 and ratchet side's tenon 1, form gap, conveniently takes off or exchange sleeve 3.
Structure as accompanying drawing 3 ratchet wrench head improves schematic diagram and accompanying drawing 4 clamp ring and sleeve fit structure schematic diagram, and wherein, clamp ring is pressed status;
For improving the coupling mechanism force of sleeve, sleeve 3 is provided with symmetrical left and right circular hole 53,54, corresponding is also provided with symmetrical left and right ratchet side mortise 11,12 on described ratchet side tenon 1, and a pair left and right steel ball 41,42 embeds ratchet side's mortise internal locking sleeve 3; When pressing down clamp ring 5, left and right steel ball 53,54 falls in groove 52, and sleeve 3 unlocks, and can take off or exchange sleeve 3;
Accompanying drawing 5, clamp ring and sleeve fit structure schematic diagram, wherein, clamp ring is at reset mode;
After sleeve 3 is put ratchet side's tenon, unclamp clamp ring 5, reset under the restoring force effect of left and right spring 61,62, and left and right steel ball 53,54 drops down onto bulge loop 51 place under gravity and headed in left and right circular hole 53,54 and left and right ratchet side mortise 11,12, sleeve 3 is fixed and can not comes off and rotate on ratchet side's tenon 1.
The utility model is easy to use, when people for leave behind clamp ring 5 time, make steel ball 4 drop on groove 52 place, unlock, then like a cork sleeve 3 can be taken off exchange.When unclamping the clamp ring 5 pressed down, automatically reset under the action of the spring to locking state.
