Embodiment
It is further to the technical scheme of invention with reference to specific embodiment in order to more fully understand the technology contents of invention
Introduce and illustrate, but be not limited to this.
In embodiment one as shown in Figure 1, quick lock clamp bracket of the present invention, including rack body 10, in addition to branch
The be hinged compressor arm 20 of frame body, the stage casing of compressor arm 20 is be hinged with the rack body 10, and the inner side of one end is compressed part 21,
The other end is connection part 21A；Connection part 21A is provided with the linkage 60 for being used for locking compressor arm；Linkage 60 includes being located at
Two connecting rods 61 between two connection parts；One end of connecting rod 61 is hinged with connection part 21A, the other end of two connecting rods 61
Hinge is big located at the inner of same self-locking mechanism 62 (i.e. pull bar 63 in Fig. 1), the moving direction of self-locking mechanism 62 and clamping direction
Cause degree in a vertical angle；The outer end of self-locking mechanism protrudes from the upper edge of clamping body 10 or lower ora terminalis, to carry out self-locking operation.Should
Pull bar is self-locking mechanism, while is also that (another power resources of clamping are that connection part is straight to one of power resources clamped
Connect as press section, press to realize the work of clamping bar, follow-up embodiment, which has, to be illustrated).
Compressor arm 20 in Fig. 1 is lever-type structure, and its pin joint is located at stage casing, pulling force of the connection part 21A by connecting rod 61
When, two connecting rods 61 are less than 180 degree in the angle that clamp bracket lateral direction is formed, and compressor arm 20 unclamp when operating,
Self-locking mechanism moves towards extreme direction in clamping body；When compressor arm is in impaction state, self-locking mechanism is towards clamping body outer end
Direction is moved, and two connecting rods are equal to 180 degree or slightly larger than 180 degree in the angle that extreme direction outside clamp bracket is formed, and provided with lock
Tight position.
Connecting rod 61 is located at the back side of clamping body 10；Self-locking mechanism 62 includes the pull bar 63 located at the clamping body back side
(the pull bar cross sectional shape in the present embodiment is square, can also be the shapes such as circle in other embodiments), and pass through screw
631 (or pin shaft structures of buckle-type fixation) are fixed on the rotating pull handle 64 of the outer end of pull bar 63.Rotating pull handle 64 is provided with one
The handle body 641 coupled with the rotation of the outer end of pull bar 63 is held, the lug boss 642 located at the side of body one of shaking hands, and positioned at another
The draw ring portion 643 (for ease of the installation of screw, draw ring portion 643 is adapted to use split-type structural) of one end.Clamping body 10 is provided with
For being slidably connected the chute 108 of pull bar；When the rotation of lug boss 642 is to the position corresponding with chute 108, pull bar 63 is in chute
Moved in 108, to realize the release operation of compressor arm 20 or clamp operation；The position corresponding with chute 108 of lug boss 642 is wrong
When opening, pull bar 63 is fixed, so that compressor arm 20 is maintained at clamped condition.The back side of body 10 is clamped to be provided with and the phase of chute 108
Corresponding cover plate 107, cover plate 107 are provided with a lock-bit notch 106, when lug boss 642 is placed in lock-bit notch 106, two
Compressor arm is in impaction state (i.e. clamped condition).
Rack body therein by magnetic, inhale or clamp etc. mode and be fixed on immobilization carrier (such as bicycle by vacuum
Vehicle frame, the console of automobile etc.), and or immobilization carrier is fixed on by modes such as bonding, thread connection, buckle, necks.Its
In, it is more convenient when being put into for gripped objects such as mobile phones, (it can be set between two parties provided with one in the lower end of rack body 10
Put) or the lug 104 of two, do not moved down with blocking gripped object, safety guarantee can also be played a part of during clamping.
The alternative solution of embodiment one is：Compressor arm uses one end radial type structure, one end of compressor arm and rack body
Be hinged, the inner side in stage casing is compressed part, and the other end is connection part, and its pin joint is located at one end, connection part by connecting rod thrust when,
Self-locking mechanism is less than 180 degree towards extreme direction movement in clamping body, two connecting rods in the angle that extreme direction in clamp bracket is formed；
When compressor arm is in impaction state, self-locking mechanism is provided with locking position (with reference to figure 1 towards extreme direction movement outside clamping body
Structure is implemented).
The another alternative solution of embodiment one is：Cover plate is not provided with lock-bit notch, is to be located at lug boss to be bordering on lug boss
Position, after pull bar is pulled out, after rotating pull handle is rotated, by lug boss stop be butted on cover plate or clamp body lower end
Edge, to form impaction state.
Another alternative solution of embodiment one is：Connecting rod 61 is arranged in the dead slot of clamping body 10, such structure, outside
Shape is attractive in appearance.Or a back shroud is set up before clamping body 10, the main part of connecting rod is covered.
In embodiment two as shown in Figure 2, the side of rack body 10 has been slidably connected coupling block 30, and coupling block 30 is fixed
There is described compressor arm 20；Rack body 10, which is provided with, is used to housing the chute 100 of coupling block 30, and in being distal to grasping part
Bottom surface is provided with the fastener 109 for being used to lock coupling block 30 and (screw or cam with hand rotating part is illustrated that in Fig. 2
Formula set lever).Using such structure, the clamp distance between two compressor arms can be adjusted, to be adapted to different in width
Gripped object, such as the mobile phone of different in width.The back side of rack body 10 employs clampingslot type fixed seat 103.Also illustrated in figure
The torsion spring 102 (a kind of embodiment of elastic body) being sheathed at compressor arm rotation.
When compressor arm is lever-type structure, connection part 21A outside forms press section 22；Can further include by
Maintaining body is pressed, so that compressor arm 20, when being resetted after pressing for the first time, compressed part 21 is maintained at stop position, second of pressing
After when resetting, compressed part 21 moves inward, and to the clamping position of inner terminal, the pressing operation of compressor arm 20 repeats in this way.This
If sample, when the last time takes out clamping thing, clamping bar can be held in stop position, when being put into gripped object for the second time, it is not necessary to
Press in advance once, it is only necessary to after gripped object is positioned over into grasping part, presses compressor arm again and release hold mode, in elastic force
In the presence of mechanism, gripped object is clamped.Specific pressing maintaining body is as shown in following two embodiments.
Embodiment three as shown in Figure 3, pressing maintaining body therein is inline type 40, near positioned at rack body 10
In the side of compressed part 21, it includes ring and is evenly equipped with the fixing pipes 41 of several guide protrusions 411 (its outer end periphery is provided with outer
Screw thread, for being fixedly connected with rack body), the stop block 42 located at the inside stage casing of fixing pipe 41, only it is butted in compressor arm 20
Push rod 43 between side and stop block 42, and rotation pushing block 44 and reset bullet between stop block 42 and the inner of fixing pipe 41
Spring 45；The periphery of stop block 42 is embedded between guide protrusions 411 space or backstop in outside guide protrusions 411 provided with several
