Specific embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1 to Figure 2, which includes a master key head 2 and a pair of of secondary key head 3, main key
The consistency of thickness of key bit 2 and secondary key head 3, secondary key head 3 are collapsibly arranged on the both sides of the master key head 2.
As shown in Fig. 5 to Figure 10, which includes the first key item 21 of a strip and a sheet of first key
Key piece 22, the both sides of the first key item 21 are respectively equipped with the one first key flank of tooth 211, which is equipped with a circle
The fixation keyhole 23 of shape, the middle part of the first key item 21 are equipped with the perforative movable notch 24 of a rectangle, the activity notch
24 head is equipped with a semi-enclosed preceding fixing threaded hole 25, and the tail portion of the activity notch 24 is equipped with a perforative rear fixing threaded hole
26.It should be noted that the height of movable notch 24 and master key head 2 and the consistency of thickness of secondary key head 3.
A dismountable retainer spring 4 is equipped between the rear fixing threaded hole 26 and preceding fixing threaded hole 25.The retainer spring 4 includes
One spring body 41, fixed column 42 before the head of the spring body 41 is equipped with one, the tail portion of the spring body 41 are solid after being equipped with one
Fixed column 43, fixed thread 421 before the outer wall of the preceding fixed column 42 is equipped with one, the tail portion of the preceding fixed column 42 are installed before being equipped with one
Notch 422, fixed thread 431 after the outer wall of the rear fixed column 43 is equipped with one, the tail portion of the rear fixed column 43 are pacified after being equipped with one
Tankage mouth 432, the preceding fixed column 42 are arranged in the preceding fixing threaded hole 25, which is arranged on the rear fixing threaded hole 26
In.
As shown in Figure 3 and Figure 4, which includes the second key item 31 of a strip and a sheet of second key
Key piece 32, the outside of the second key item 31 are equipped with the one second key flank of tooth 312, and the inside of the second key item 31 is matched equipped with one
Splice grafting contacting surface 311, second key piece 32 are equipped with a semicircular fixed key mouth 33, and the radius of the fixation key mouth 33 is big
In the fixation keyhole 23, hereinafter will continue to be illustrated.
The inner wall of the second key item 31 is equipped with an outwardly projecting cooperation prominent 34 and a cooperation being recessed inwardly is recessed
Slot 35, the cooperation protrude 34 and match relative to the projecting height D1 of the coordinate contact surfac 311 more than the mating groove 35 relative to this
The cup depth D2 of splice grafting contacting surface 311, which, which protrudes, is equipped with a perforative prominent through-hole 341 in 34, which passes through
Wear the protrusion through-hole 341.
The application method of the folding cross key 1 is illustrated below.
As shown in Fig. 1 and Figure 11 to Figure 14, at this point, the folding cross key is in unfolded state.Secondary key head 3
It is mutually perpendicular to respectively with master key head 2, forms a complete cross key, be user-friendly for opening the door or close the door.At this point,
The cooperation of secondary key head 3 protrudes 34 and is inserted respectively into movable notch 24, and coordinates prominent 34 to head into another secondary key head 3
In mating groove 35.Since cooperation prominent 34 is opposite more than mating groove 35 relative to the projecting height D1 of coordinate contact surfac 311
In the cup depth D2 of coordinate contact surfac 311, therefore, when cross key rotates in keyhole, secondary key head 3 can always with master
The holding of key bit 2 is mutually perpendicular to, crooked without occurring.
As shown in Figure 15 to Figure 17, at this point, the folding cross key is in folded state.User is directly by secondary key
Key bit 3 is laterally pulled out from the movable notch 24 of master key head 2, at this point, cooperation prominent 34 is detached from corresponding mating groove 35,
And secondary key head 3 is folded to the both sides of master key head 2.Due to the elasticity of spring body 41, as shown in figure 16, cooperation is prominent
Go out 34 tightly to be clasped by spring body 41, at this point, cooperation prominent 34 is protruded in the outside of movable notch 24, complete to fold.
The installation method of the folding cross key is described below.First, a pair of of secondary key head 3 is respectively put into work
In dynamic notch 24 so that prominent through-hole 341 is tentatively aligned.Then, the preceding fixed column 42 of retainer spring 4 is extended through into prominent through-hole
341 so that before preceding fixed column 42 drops into fixing threaded hole 25, rear fixed column 43 is temporarily stayed in into fixed keyhole 23 at this time
In.Then, screwdriver is passed through into rear fixing threaded hole 26 and spring body 41, and resists the preceding installation notch of preceding 42 tail portion of fixed column
422, rotate screwdriver so that before preceding fixed column 42 is securely fixed in fixing threaded hole 25.Finally, after rear fixed column 43 is filled in
In fixing threaded hole 26, screwdriver is resisted to the rear installation notch 432 of rear fixed column 43, rotates screwdriver so that rear fixed column 43 is secured
Ground is fixed in rear fixing threaded hole 26.Since preceding fixed column 42 and rear fixed column 43 are fixed, spring body 41 will not
It comes off from movable notch 24, even if secondary key head 3 is completely pulled out of, will not be detached with master key head 2.
In the key collector for using KEYSMART etc, isolation nylon ring plate is respectively placed in consolidating for master key head 2
Determine the both sides of keyhole 23.Since the radius of the fixation key mouth 33 of secondary key head 3 is more than fixed keyhole 23, and nylon is isolated
The radius of ring plate is less than fixed key mouth 33, and therefore, secondary key head 3 carries out collapsible, will not occur do with nylon ring plate be isolated
It disturbs.After the completion of folding, directly the cross key after folding can be ploughed under in key collector, with other sheet keys simultaneously
Row's storage.
Second of embodiment for the secondary key head of the present invention as shown in figure 18.At this point, secondary key head 300 only includes
One key item, this secondary key head 300 are more suitable for the key collector of long shaft, can store more keys.This secondary key
The application method of head is identical with secondary key in the first implementation.
The folding cross key of the present invention has the following advantages：The storage space of cross key is effectively reduced, it is convenient
Storage is suitble to various types of key collector.
Not limited to this, any change or replacement expected without creative work should all cover the guarantor in the present invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
