Description
Technical field
The utility model relates to a kind of locking device, the especially a kind of fast lock device that can realize quick locking.
Background technique
The industrial field various device need be by panel and frame connection, and the installation of panel generally is threaded with plain screw, panel screw etc. traditionally.The relative reliability that is threaded height, but dismounting needs instrument, and also the slow efficient of speed is low.So need a kind of Placement fast equipment to be locked on the frame on the reality.
At present, there are the demand of changing parts fast in part industry equipment and military hardware, and traditional screw mounting type can not adapt to such needs.And the handle of general quick mounting dismounting often volume is big, mechanism's complexity is not suitable for being applied in little space, or on the mini-plant.Have, some small-sized fast lock quick detach handle volumes are little, be connected defective tightness but material is nonmetallic material with equipment, and join strength are low again, and reliability is not high.
So, need a kind of new technological scheme to address the above problem.
The model utility content
The purpose of this utility model is the deficiency that exists at prior art, and the fast lock device that a kind of volume is little, connection reliability is high is provided.
For achieving the above object, the fast lock device of the utility model can adopt following technological scheme:
A kind of fast lock device, this fast lock device comprise presses embedding steel bushing and pin handle, described pressure embedding steel bushing to comprise pedestal and a pair of forearm that extends to same direction from pedestal; Be provided with the through hole that is used to accommodate described pin handle in this pressure embedding steel bushing, this through hole runs through the two ends of pressing the embedding steel bushing; The front end of the inboard of described two forearms respectively has a pair of relative inclined-plane, and the distance between the outer end in this two inclined-plane is more close; The handle that described pin handle has the body of rod that cooperates with described through hole, the anticreep head that is positioned at lever front end and is positioned at body of rod rear end, the described body of rod has thick bar portion and thin rod part, and the body of rod is provided with the blocked part.
Compare with background technique, the fast lock device of the utility model is provided with a pair of forearm and runs through the through hole of pressing embedding steel bushing two ends by pressing the embedding steel bushing, and, the front end of the inboard of described two forearms respectively has a pair of relative inclined-plane, and the distance between the outer end in this two inclined-plane is more close, like this after the pin handle inserts, thick bar portion struts two forearms by the guiding on inclined-plane, make two forearms outside resiliently deformable respectively, two forearms are fastened on the connected equipment, simultaneously, the blocked part on the body of rod can prevent that connected equipment from coming off.Like this, rely on the insertion of pin handle can realize quick locking.
Description of drawings
Fig. 1 is the structural representation of the fast lock device of the utility model, and has showed the state in this fast lock device use.
Fig. 2 is the structural representation of pressing the embedding steel bushing in the fast lock device of the utility model.
Fig. 3 is the structural representation of pin handle in the fast lock device of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also Fig. 1 to shown in Figure 3, the utility model discloses a kind of fast lock device 100, this fast lock device 100 is made for metallic material, and it comprises the pin handle 30 of pressing embedding steel bushing 20 and cooperating with this pressure embedding steel bushing 20.Described pressure embedding steel bushing 20 comprises pedestal 21 and a pair of forearm 22 that extends to same direction from pedestal 21.Be provided with the through hole 23 that is used to accommodate described pin handle 30 in this pressure embedding steel bushing 20, this through hole 23 runs through the two ends of pressing embedding steel bushing 20.The front end of the inboard of described two forearms 22 respectively has a pair of relative inclined-plane 24, and the distance between the outer end in this two inclined-plane 24 is more close.Described through hole 23 has and is positioned at described inclined-plane 24 1 ends, i.e. the extending port 231 of forearm 22 ends and the insertion mouth 232 that is positioned at pedestal 21 1 ends, and described insertion mouthfuls 232 is big than extending port 231.The outer surface of this pressure embedding steel bushing 20 also has anti-skidding line 25 to make things convenient for user's operation.Described pedestal 21 has outwards protruded out positioning convex portion 211 with the joint of forearm 22.
Described pin handle 30 has the body of rod 31 that cooperates with described through hole 23, the handle 33 that is positioned at the anticreep head 32 of the body of rod 31 front ends and is positioned at the body of rod 31 rear ends.The described body of rod 31 has thick bar portion 311 that links to each other with handle 33 and the thin rod part 312 that links to each other with anticreep head 32, is connected with the round platform bar 313 of frustoconic shape between described thick bar portion 311 and the thin rod part 312, and the thick bar portion 311 of the body of rod 31 is provided with blocked part 314.Described thick bar portion 311 diameters are greater than extending port 231 diameters of described pressure embedding steel bushing 20.The front end of described anticreep head 32 is an arc surface, is inserted in the described through hole 23 to make things convenient for anticreep head 32.
During use, at first prepare the device (being frame 400 and device panel 500 in the present embodiment) that two needs connect, and will press embedding steel bushing 20 to embed in the device panel 500 top faces to frame 400, and make pressure embedding steel bushing pass frame 400, be resisted against on the frame 400 until positioning convex portion 211.Then, pin handle 30 in the insertion mouth 232 of pressing embedding steel bushing 20 and advance, and is stretched out from extending port 231 under the guiding on inclined-plane 24 in described forearm 22.Because the diameter of described thick bar portion 311 is greater than extending port 231 diameters of described pressure embedding steel bushing 20, so when extending port 231 stretches out in thick bar portion 311, described two forearms 22 are strutted and the outside resiliently deformable of difference by thick bar portion 311, two forearms 22 are fastened on connected frame 400, the panel 500, press embedding steel bushing 20 with connected frame 400, panel 500 stable being immobilizated in thereby make.30 propellings of pin handle are resisted against on the device panel 500 until described blocked part 314, frame and device panel 500 are fit together closely, thereby make frame 400 and device panel 500 stable being connected.
The fast lock device 100 of the utility model relies on presses embedding steel bushing 20 and the 30 simple insertion operations of pin handle can realize quick locking, connects the locking of implement device fast compared to traditional screw.And this fast lock device 100 adopts metallic material, can improve the intensity of connection significantly.
