The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is made an into detailed description.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; The utility model provides a kind of internal-lock folding joint; Comprise top connection 1 and lower adaptor 2, top connection 1 is connected with rod member respectively with lower adaptor 2, and top connection 1 can be hinged involutory through jointed shaft 12 with lower adaptor 2; Top connection 1 is provided with first groove 3 with the involutory surface of lower adaptor 2; In first groove 3, have and to move and an end has the grip block 4 of flange along it, be provided with second groove 5, the flange of grip block 4 and the 5 suitable settings of second groove at the inner edge of lower adaptor 2; The end that grip block 4 has a flange is resisted against the inner edge of top connection 1 through retracing spring 6, in first groove 3, also is provided with the other end bonded assembly shifting component with grip block 4.Shifting component can be made up of eccentric wheel 8, slide block 9 and handle 10, and eccentric wheel 8 is articulated on the said jointed shaft 12, the also slide relative but slide block 9 and eccentric wheel 8 lean, and handle 10 is positioned on the eccentric wheel 8 and stretches out in top connection 1 and the outside of lower adaptor 2.Eccentric wheel 8 is designed to when it goes to it farthest edge pushes against slide block 9 apart from the axle center, and the flange of grip block 4 is inserted in second groove 5.The slide block 9 of shifting component is connected through pipe link 11 with the other end of grip block 4.The tail end of first groove 3 has the 3rd groove, and the width of the 3rd groove is less than the width of first groove 3, and retracing spring 6 places in the 3rd groove.
When needs were locked folding joint, turning handle 10 to the eccentric wheel 8 that makes progress went to its edge nearest apart from the axle center and contacts when leaving slide block 9 with slide block, and grip block 4 is motion backward under the restoring force effect of retracing spring 6; Close top connection 1 and lower adaptor 2; And rotate handle 10, make eccentric wheel 8 contact with slide block 9 and promote slide block 9 and move forward, the power that pipe link 11 transmits from slide block 9; And promotion grip block 4 travels forward and compression reseting spring 6; When eccentric wheel 8 went to it farthest edge pushes against slide block 9 apart from the axle center, the flange of grip block 4 was inserted in second groove 5, has realized the locking of top connection 1 and lower adaptor 2.When needs are removed the locking of folding joint; Turning handle 10 makes progress; The edge of the feasible eccentric wheel 8 that contacts with slide block 9 is more and more nearer apart from its axle center, and grip block 4 is motion backward under the restoring force effect of retracing spring 6, and its flange withdraws from second groove 5 gradually; Can realize that top connection 1 contacts with the locking of lower adaptor 2 this moment, and top connection 1 is in the state that can fold with lower adaptor 2.
The internal-lock folding joint of the utility model; The design of the upper and lower joint that employing is articulated and connected; In top connection, be provided with the grip block that an end has flange; In lower adaptor, be provided with the groove suitable, promote grip block through shifting component and move forward and backward and make flange insert groove or from groove, extract, realize the locking of folding joint or unclamp with flange.The device of the utility model makes grip block move the folding that the short range straight line can be accomplished folding joint through having the eccentric use of handle, and this device has good locking effect, and is easy to operate, and structure design is simple.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
