The front part of each slit is in a linear type and the back part is in an oblique line type. An eccentric locking wheel groove is arranged on the lock plate; the back end of the lock plate can be bent into a U shape, and the end face of the back end is a moving working face for the lock plate and an arc-shaped limiting face which is tangential with the working face.

Description

Three clip spring lock
The utility model relates to a kind of connection fastener that is used to connect exhibition apparatus---three clip spring lock.This three clip spring lock is used for the connection of movable exhibition framework.
Chinese patent ZL99225584.8 is a kind of three clip spring lock that the applicant proposes, though this lockset improves original tapered end, Shang Youke is improvements again, stop bit weak effect during as eccentric lock wheel Rotate 180 °,
The utility model is the improvement to above-mentioned patent, proposes a kind of increase plate tongue width, increases the having more rationally of arc stop surface, more superior three clip spring lock.
The technical solution of the utility model is: a kind of three clip spring lock, it is made of lock housing, jam plate, three parts of eccentric lock wheel, there are two on the jam plate from the middle slit crack that extends to front end always, thereby make be formed with on the jam plate about two sides and middle three plate tongues, plate tongue front end is U-shaped crotch (also claiming pawl), it between the crotch back-flexing each other, left and right sides plate tongue symmetry, two partly before and after the slit had, the front portion is type linearly, the rear portion is bias type, and the afterbody of jam plate has the U-shaped crotch, and its end face is work plane and the arc stop surface that jam plate moves.
Owing to adopt technique scheme, when the eccentric lock wheel rotates to 180 °, the eccentric lock wheel does not only depend on the eccentric grove stop bit on the jam plate, simultaneously, the work plane of eccentric lock wheel is subjected to the retardance of arc stop surface on the jam plate, has increased the ability that retardance eccentric lock wheel is rotated further, thereby improved the stop bit effect, add the appropriate design slit, thereby obtain three plate tongues that bearing surface is big, increased the rigidity of plate tongue.Finish the invention task.
Fig. 1 is the overall construction drawing of three clip spring lock.
Fig. 2 is the lock housing embodiment of the utility model three clip spring lock.
Fig. 3 is the jam plate embodiment of three clip spring lock.
Fig. 4 is the front view of Fig. 3.
Fig. 5 is the eccentric lock wheel front view of three clip spring lock.

Be described in detail the utility model below in conjunction with accompanying drawing.
Three clip spring lock of the present utility model is to be made of lock housing 1, jam plate 2, eccentric lock wheel 3, thereby has two on the jam plate 2 from the middle slit that extends to front end always, and this slit forms with mould is die-cut; Form left and right and middle three plate tongues, the front end of plate tongue is U-shaped crotch (also claiming pawl), between the crotch back-flexing each other, wherein left and right two plate tongues, 7,8 symmetries, the direction unanimity of crotch bending, middle plate tongue 9 about two sides wide, and the intermediate plate back of tongue is wideer than anterior, and two partly before and after the slit had, and anterior slit 10 is type linearly, slit, rear portion 11 is bias type, also has eccentric lock race 12 on jam plate 2; The rear end of jam plate 2 bends to U-shaped, the work plane that its end face 13 moves for jam plate 2, and tangent with it is arc stop surface 14.
On the eccentric lock wheel 3 of three clip spring lock stop bit cam 31 is arranged, the inclined-plane 19 of the stop bit plane 16 and the usefulness of stepping down is arranged on the stop bit cam 31.On the eccentric lock wheel 3 of three clip spring lock eccentric lock wheel work plane 17 and positioning cylindrical surface 18 are arranged.
The breach 4 of stepping down on the lock housing 1 of three clip spring lock.On the lock housing 1 of three clip spring lock locating hole 5 is arranged.Step down breach 4 and locating hole 5 respectively in upper and lower two sides of lock housing 1.
The breach 4 of stepping down of lock housing 1 one sides, to allow the arc stop surface that increases on the unlock plate, there is a locating hole 5 at its center, and there is a circular arc locating surface 6 locating hole 5 front portions.(Fig. 2)
Two on the jam plate 2 form with mould is die-cut from the middle slit that extends to front end always, form left and right and middle three plate tongues, the front end of plate tongue is U-shaped crotch (also claiming pawl), between the crotch back-flexing each other, wherein left and right two plate tongues, 7,8 symmetries, the bending direction unanimity of crotch.Middle plate tongue 9 about two sides wide, and intermediate plate tongue 9 rear portions are wideer than anterior.The slit has two partly, anterior slit 10 is type linearly, slit, rear portion 11 is bias type, on jam plate, also have eccentric lock race 12, the rear end of jam plate 2 bends to U-shaped, the work plane that its end face 13 moves for jam plate, the arc stop surface 14 (Fig. 3) tangent with it has feet 15 (Fig. 4) at the rear of intermediate plate tongue
On the eccentric lock wheel 3 the stop bit cam is arranged, the inclined-plane 19 of the stop bit plane 16 and the usefulness of stepping down is arranged on the stop bit cam.Also has eccentric lock wheel work plane 17 on the eccentric lock wheel 3, positioning cylindrical surface 18 (Fig. 5, Fig. 6)
During the three clip spring lock assembling, elder generation by inserting in the lock housing 1 rear end cavity, with eccentric lock wheel 3 puts into jam plate 2 on eccentric lock race after the insertion with jam plate 2, promotes jam plate forward, makes in eccentric lock wheel 3 locating holes 5 that enter in the lock housing 1.At this moment, three pawls of three clip spring lock enter in three grooves of lock housing front end, under the effect of jam plate feet 15, the positioning cylindrical surface 18 of eccentric lock wheel 3 are close on the locating surface 6 of lock housing 1.Composition is made of the lockset of one lock housing 1, jam plate 2, eccentric lock wheel 3.
During use, press down eccentric lock wheel 3, three clip spring lock is packed in the cavity of special-shaped hollow material 20, on the face of special-shaped hollow material 20, be processed with fixing eccentric lock and take turns 3 hole 21, thereby three clip spring lock is fixed on the section bar 20.
The special-shaped hollow material 20 that three clip spring lock is housed is connected with the section bar 22 of overlap joint, the head three-jaw of three clip spring lock is inserted in the section bar 22 that connects, special spanner is inserted in the plum blossom scallop on the eccentric lock wheel 3, rotating eccentricity lock wheel 3, under the effect of eccentric lock wheel work plane 17, jam plate 2 is moved backward, the three-jaw of three clip spring lock jam plate head opens to two limits along the lock housing inclined-plane in the process that moves backward, thereby the section bar of two connections is buckled together, and formation is fixedly coupled.(Fig. 7)
A series of technological improvement of the present utility model strengthens the width of three pawls, thereby has increased the strength and stiffness of each pawl, has improved the supporting capacity of three clip spring lock; When eccentric lock was taken turns 2 Rotate 180s °, the stop bit plane 16 on the stop bit cam 31 of eccentric lock wheel 3 fitted with eccentric lock race 12 on the jam plate 2 on the one hand, plays the stop bit effect.Simultaneously, the arc stop surface 14 at jam plate 2 afterbody places, the rotation of blocking the eccentric lock wheel makes the eccentric lock wheel can not continue rotation, thereby plays the stop bit effect again, has improved the stop bit effect.
