Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Shown in Fig. 7, a kind of firmly easy U-shaped support of the present invention, comprise the first stop 1, second stop 2 and the stake body 3 for installing the first stop and the second stop, first stop 1 has the recessed district 1A in location of opening upwards, second stop 2 superposition to be arranged on the first stop 1 and to have and stretches into the first stop and locate projection 2A in recessed district, first stop is located recessed district 1A and is had driving inclined-plane, second stop 2 has and rotates locating shaft 2B away from during the second stop direction horizontal movement by what drive inclined-plane and projection 2A to coordinate driven rotary to make the second stop 2 open relative to the first stop 1 at the first stop 1, second stop 2 is also provided with and when external force disappears, relative first stop of the second stop is drawn in and pass through the flexible restoring organ (the present embodiment adopts back-moving spring 4) that drives inclined-plane and projection to coordinate drive first stop to reset, first stop 1 and the second stop 2 phase have the locking face coordinating and hold locking tightly to the inside.Second stop 2 drives the first stop 1 draw in thus hold locking tightly under flexible restoring organ effect, manually push away and open the first stop 1 when moving horizontally, the driving inclined-plane of the first stop 1 drives the second stop rotate around rotation locating shaft 2B thus open unblock, flexible restoring organ savings elastic potential energy simultaneously.
The inward flange that stake body 3 is met to the first stop 1 has locating notch 3Z, and the first stop 1 top has and to coincide the positioning step 1Z located with stake body locating notch 3Z under thing to be locked drives to off-direction motion.Have individual locking structure between first stop and stake body, this locking structure is the locking thing design for original shape or 6 jiaos and 8 dihedrals, and the thing to be locked being perpendicular with locking face contact surface does not need this locking structure.Because the first stop opposite brackets body can to the space of stake body opening direction movement, positioning step is had at the top of the first stop, match with the locating notch on stake body, when the first stop moves up under the drive of thing to be locked, locking face on first stop can decompose locking thing to upper lifting force, the power that the first stop can be made to have individual level walk about, the first stop will be made like this to unlock, also can unlock the second stop under the drive of the first stop simultaneously, such lockset just can take out from stake body, lockset easily comes off in car driving process, therefore circular or connect on rotund locking thing, need to arrange a locking structure, making to lock thing can not Automatic-falling.Here locking structure is that the first stop tip position of starting shooting on stake body has the breach matched with step, when the first stop is upwards walked under the effect locking thing, step on first stop snaps in the breach on stake body, first stop can not have been walked about in the horizontal direction again, and thing to be locked so just can not depart from stake body.
In the present embodiment, for ease of processing and assembling, the first stop 1 and the second stop 2 include transverse arm and trailing arm, and the transverse arm superposition of the second stop 2 is arranged on the transverse arm of the first stop 1; First stop transverse arm 1C free end stretches out outside stake body 3, the first stop transverse arm 1C other end extends upward trailing arm 1D, first stop transverse arm 1C has the recessed district 1A in location near the position of trailing arm 1D, the driving inclined-plane of locating in recessed district is positioned at and the side near free end; Arrange projection 2A below second stop transverse arm 2C free end, the second stop transverse arm 2C other end extends upward trailing arm 2D, has and rotate locating shaft 2B outside trailing arm 2D.
For ease of dismounting, stake body 3 one sidewall has the first groove 3A put into for the first stop, another sidewall that stake body 3 is relative with the first groove 3A place sidewall has the through hole 3C stretched out for the first stop cross arm free end, stake body 3 diapire has the second groove 3B put into for the second stop 2.
Stake body 3 is T-shaped for the second groove 3B putting into the second stop, stake body inwall rotates to have above the breach that locating shaft coordinates at the second groove and the second stop and rotates locating shaft with the second stop and coordinate spacing spacing zone, and spacing zone has the smooth contact surfaces for rotating locating shaft position rotating.
There is in stake body 3 longitudinal section to take the shape of the letter U or limiting plate 3D(the present embodiment of rectangle is U-shaped), limiting plate 3D upper end open, limiting plate 3D has and stretches into limiting plate inwall institute region the 3rd groove (this groove is communicated with the first groove 3A), the 4th groove 3F for the first stop 1 with the trailing arm of the second stop 2, limiting plate inwall region portion of institute and the first stop trailing arm locking face, the second stop trailing arm locking face form ' locked ' zone.
Two vertical baffles (3G, 3H) are extended downwards bottom the U-board of stake body limiting plate 3D, the flexible restoring organ of the second stop comprises back-moving spring 4, back-moving spring 4 one end and stake body limiting plate 3D offset, and the other end stretches into the recessed district inner position at the second stop projection 2A back side.
First stop trailing arm 1D and the second stop trailing arm 2D opposite sides all have locking projections (1X, 2X), locking projections (1X, 2X) seamlessly transits downwards and forms locking face, locking face can be various shape, according to the alteration of form of locking thing, the lower aspect of locking projections is exactly locking face, is combined, become the locking face of this programme by the first stop and the second stop locking projections two locking faces, strengthen locking firmness, the present embodiment locking face is arc-shaped.The locking projections of the first stop trailing arm and the second stop trailing arm upwards smoothly extends to form bell mouth shape guiding face, facilitates thing to be locked to slip into smoothly.
When opening for preventing the second stop and stake body inwall rigid contact, the back side that the second stop trailing arm 2D is relative with locking projections 2X has the tapering shunk to upper end, namely forms the accommodating area for the second stop activity.
Stake body 3 has the tubular cavity 3L of locking region axis perpendicular, and cavity shape, can be square according to the lock body alteration of form of lockset, circular, polygon, also can abnormity, and tubular cavity 3L side is communicated with limiting plate inwall institute region, all the other inner surfaces enclose.Stake body 3 has vertically disposed three pieces of location-plate 3K mutually on tubular cavity 3L areas outside surface, can be fixed from three directions to stake body, and assembling mode is enriched, and versatility is good.The rib being less than location-plate bottom location-plate 3K by area is connected with stake body 3, and location-plate 3K both sides of the edge have and are arranged at intervals with retention Hp limit 3P, and retention Hp limit 3P and corresponding location-plate edge form the positioning guide rail of one end open; Location-plate 3K end face has guide chute 3Q, and the other end that guide chute 3Q is relative with positioning guide rail openend has opening, and formation is stablized and is convenient to the detent mechanism of assembling.
Although the present invention has illustrated by reference to preferred embodiment and has described, those of ordinary skill in the art should understand, and can be not limited to the description of above-described embodiment, in the scope of claims, can do the various changes in form and details.
