Description
Technical field
The utility model relates to jacking equipment field, particularly relates to a kind of jack switching device.
Background technology
Existing jack switching device, its shift knob does not have locking switch function, when jack work, exist due to operating personnel or other people's misoperation touch switch button, decline suddenly when making jack in running order or jack is in non operating state time unexpected jack-up potential safety hazard that the personnel of surrounding or article are damaged.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and reliable jack switching device.
The technical scheme realizing the utility model object is: a kind of jack switching device, and it comprises Switch main body and shift knob; Described switching device also comprises a button locking plate, described button locking plate to be installed on Switch main body and spacing by locking plate positioner, described button locking plate offers spacing hole, button locking plate is enclosed within shift knob by spacing hole, the sidewall of described shift knob is provided with lock slots, described lock slots and the sealed direction of button latch sheet are oppositely arranged, and the height of described lock slots and the thickness of button locking plate match, and described spacing hole length is greater than shift knob diameter.
Further, described button locking plate offers lock in place hole, in described Switch main body, locking ball is installed, described locking ball be positioned at spacing hole side button locking plate embed lock slots time lock in place hole below; Be installed with compression spring below described lock in place steel ball, size and the lock in place hole of described locking ball match.The setting of lock in place hole and locking ball, spacing further to button locking plate, ensure its accuracy operated.
Further, described lock in place hole is other offers activity orientation hole, and the interval in described lock in place hole and activity orientation hole is slightly larger than the cell body degree of depth of lock slots.Realize to switching device unlock after spacing.
Further, described button locking plate positioner is a locking plate slide block, and described locking plate slide block is fixedly installed on Switch main body, and described button locking plate is between Switch main body and locking plate slide block, coordinate with locking plate skid, play effect that is fixing and guided push button locking plate.
The utility model is transformed existing switching device, add button latch chip architecture, it coordinates with shift knob, realize the locking of shift knob: by promoting button locking plate, the button locking plate of spacing hole side embeds lock slots, locking ball ejects and snaps in lock in place hole, and now shift knob is locked, and can not operate; Make locking ball ejection snap in activity orientation hole when pushing back button locking plate, switch unlocks.The setting of button latch chip architecture substantially increases the security performance of jack operation.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of jack switching device embodiment described in the utility model embodiment;
Fig. 2 is the enlarged drawing of part A in Fig. 1;
The button locking plate that Fig. 3 is jack switching device described in the utility model embodiment and locking plate slide block fit structure elevational schematic view.
Embodiment
Now 1-3 describes better embodiment of the present utility model in detail by reference to the accompanying drawings: a kind of jack switching device, and it comprises Switch main body 1, first shift knob 11, second switch button 12, button locking plate 3 and locking plate slide block 4; Described locking plate slide block 4 is fixedly installed on Switch main body 1, and described button locking plate 3, between Switch main body 1 and locking plate slide block 4, is slidably matched with locking plate slide block 4; Described button locking plate 3 offers two spacing holes 31, described button locking plate 3 is by 31 being enclosed within the first shift knob 11 and second switch button 12 in two spacing holes, first shift knob 11 and second switch button 12 offer lock slots 21 respectively, described lock slots 21 is positioned at button latch sheet sealed direction first shift knob 11, second switch button 12 with on the contact-making surface of button locking plate 3, the height of described lock slots 21 and the thickness of button locking plate 3 match, and the length L of described spacing hole 31 is greater than the first shift knob 11 and second switch button 12 diameter D.Described button locking plate 3 offers lock in place hole 32 and activity orientation hole 33 between two spacing holes 31 respectively, described lock in place hole 32 is positioned at the left side in activity orientation hole, button latch sheet sealed direction 33, and the interval a in lock in place hole 32 and activity orientation hole 33 is slightly larger than the cell body degree of depth b of lock slots 21; In described Switch main body 1, locking ball 5 is installed, described locking ball 5 be positioned at spacing hole 31 side button locking plate embed lock slots 21 time lock in place hole 32 below, described locking ball is installed with compression spring 65 times, and the size of described locking ball 5 and lock in place hole 32, activity orientation hole 33 match.
Its operation principle is: promote button locking plate, and the button locking plate of spacing hole side embeds lock slots, and locking ball ejects and snaps in lock in place hole, and now shift knob is locked, and can not operate; When pushing back button locking plate, spacing hole goes out of lock groove, and locking ball ejects and snaps in activity orientation hole, and now switch unlocks, and can carry out switching manipulation.
The utility model locking plate positioner is used for spacing to button locking plate, its structure is not limited to locking plate slide block, the compressing tablet be slidably matched with button locking plate can also be set on the horizontal plane of button locking plate front and back end, or the compressing tablet be slidably matched with button locking plate is set in the middle part of button locking plate, ensure its stability of sliding.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
