Abstract
The invention discloses a locking device with an arc groove. The locking device comprises a substrate, a control bar with one end being hinged to the substrate, a locking bar and a projection which is fixed on the substrate, wherein the locking bar is hinged to the other end of the control bar, the locking bar is provided with an arc groove surrounding the projection, the control bar is provided with a lock ring with a notch and a support which is used for the lock ring to pass through and slide, and the notch of the lock ring is bigger than the transverse size of the locking bar. When the locking is needed, the locking bar rotates along the hinge point, the locking bar can be fixed by rotating the lock ring, two through holes do not need to be aligned by experience, a fixed pin is not needed, and the simplicity in operation is realized. The lock ring for fixing the locking bar is arranged on the control bar, when in locking, the locking bar and the control bar are overlapped, no more space is occupied, and the interference on other mechanisms can be avoided.
Description
Technical field
The invention belongs to technical field that is fastening or fixed mechanism.
Background technique
Controlling rod is connected with other mechanisms usually, we often need by controlling rod locking to lock other mechanisms, and existing locking is usual in the following way: on controlling rod and pedestal, all have through hole, when needing locking, two through hole need be aimed at, and by fixing pin, controlling rod is locked on pedestal.
Although adopt aforesaid way structure simple, very inconvenient during operation, be mainly reflected in the step of two through hole aligning.Because next through hole is blocked, can only aim at by feel, make the process efficiency of locking not high.
Summary of the invention
The invention provides a kind of locking device with arc-shaped slot, to solve existing locking device when locking, with feeling the problem of aiming at two through hole on controlling rod and pedestal.
In order to solve the problems of the technologies described above, the invention provides following technological scheme: a kind of locking device with arc-shaped slot, comprise pedestal, one end be hinged on controlling rod on pedestal, locking lever and the projection that is fixed on pedestal, locking lever is hinged on the other end of controlling rod, locking lever is provided with the arc-shaped slot that projection can be surrounded, described controlling rod is provided with lock ring jaggy and passes and the support slided for lock ring, and the breach of lock ring is greater than the transverse dimension of locking lever.
The transverse dimension of locking lever refers to the size of locking lever in the plane vertical with locking lever length direction (i.e. the Normal direction of movement locus) herein.
Principle of the present invention is: when needing controlling rod to lock, and holds locking lever and controlling rod is rotated.When arc-shaped slot and the projection contacts of locking lever, by locking lever rotation, projection can arrive in arc-shaped slot, and locking lever can be threaded to and overlap with controlling rod.At this moment, by the notch alignment locking lever of lock ring, when bar to be locked enters in lock ring, rotate lock ring, dispose on the track of locking lever movement locus by lock ring seal, locking lever just can not continue motion.
Compared with prior art, the invention has the advantages that: when 1, needing locking, locking lever is rotated along articulating point, by rotating lock ring, locking lever being fixed, do not need with sensation, two through hole to be aimed at, also do not need to prepare fixing pin, simple to operate.2, the lock ring for fixedly locked bar is arranged on controlling rod, during locking, locking lever and controlling rod overlap, and can not take too much space, avoid interfering with other mechanisms.
Further, protruding quantity is at least two, and controlling rod is provided with spring section.Can lock controlling rod in multiple position, the projection when front is not the position needing location, and Compress Spring section, just can avoid the projection in front, until arrive the projection needing position location.
Further, described locking lever is round bar, and the breach of lock ring is greater than the diameter of locking lever, and locking lever could pass through from the breach of lock ring.
Further, described locking lever is square bar, and the breach of lock ring is greater than the length of side of locking lever, and locking lever could pass through from the breach of lock ring.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of the locking device embodiment of band arc-shaped slot of the present invention.
Embodiment
Reference character in Figure of description comprises: pedestal 1, controlling rod 2, locking lever 3, projection 4, lock ring 5, arc-shaped slot 6, spring section 7.
Embodiment 1
As shown in Figure 1, a kind of locking device with arc-shaped slot 6 in the present embodiment, the projection 4 comprising pedestal 1, the upper end thereof controlling rod 2 on pedestal 1, columned controlling rod 2 and be fixed on pedestal 1.Locking lever 3 is hinged on the lower end of controlling rod 2, and locking lever 3 is provided with the arc-shaped slot 6 that can surround protruding 4.Described controlling rod 2 is provided with lock ring 5 jaggy and passes and the support slided for lock ring 5, and the width at the narrowest place of breach of lock ring 5 is 1.2 times of locking lever 3 diameter.The quantity of protruding 4 is two (projection 4 on the left side and the projections 4 on the right), and controlling rod 2 is provided with can by the spring section 7 compressed.
When the projection 4 that controlling rod 2 needs on the left side is located, operating as follows: hold locking lever 3, driving controlling rod 2 along rotating clockwise.When the arc-shaped slot 6 on locking lever 3 is soon when the projection 4 on the right, upwards withstands controlling rod 2, make the shorten length of controlling rod 2, thus make locking lever 3 avoid the projection 4 on the right.When the projection 4 that the right avoided by locking lever 3 contacts with the projection 4 on the left side, by locking lever 3 along articulating point rotation, protruding 4 can arrive in arc-shaped slot 6, and locking lever 3 can be threaded to gradually and overlap with controlling rod 2.When locking lever 3 soon overlaps with controlling rod 2, the breach of lock ring 5 is exposed, when locking lever 3 is entered in lock ring 5 by breach, when locking lever 3 enters in lock ring 5 completely, the breach of lock ring 5 is rotated 90 degree, always blocks locking lever 3, make it not be rotated further.
Embodiment 2
The present embodiment difference from Example 1 is, what locking lever 3 adopted is square bar instead of round bar, and the size that breach is corresponding should be just the length of side being greater than square bar, and locking lever 3 just can have passed from the breach of lock ring 5.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
