Detailed Description
Examples
Referring to fig. 1 to 3, the limiting mechanism in the drawings is a preferred scheme of the present invention, and comprises a pawl 1, a push rod 2, a push rod support plate 3, a return tension spring 4, a left rack 5, a main frame 6, a left baffle 7, a push rod spring 8, a ratchet-gear set 9, a right rack 10, a right baffle 11 and the like.
The ratchet wheel of pawl 1, push rod 2, push rod support plate 3, push rod spring 8 and ratchet wheel-gear train 9 constitutes the push rod-ratchet wheel subassembly of stop gear, ratchet wheel-gear train 9 is whole to be assembled on push rod support plate 3 through the bearing rotation, wherein the ratchet wheel is located the upper surface of push rod support plate 3, pawl 1 is rectangular shape, one end is the pawl end, the other point is the tail end, the mid portion of pawl sets up the round hole, and assemble on push rod support plate 3 through the round pin axle swing, the pawl end can with the unidirectional interlock of ratchet wheel and separation through the swing, the tail end of pawl is connected with push rod 2, through push rod 2 manipulation pawl swing, can lock the ratchet and carry out unidirectional rotation when pawl and ratchet interlock, ratchet and the free rotation of ratchet wheel and gear after the separation.
Specifically, push rod 2 is rectangular member, is equipped with two sets of kidney-shaped holes along length direction on it, is equipped with two sets of pin on push rod mounting plate 3, and the sliding inlays respectively and inlays in two sets of kidney-shaped holes of push rod 2, realizes the straight line sliding assembly of push rod 2 on push rod mounting plate 3. Because pawl 1 is the oscillatory motion, push rod 2 is rectilinear motion, in order to make the rectilinear motion of push rod 2 drive pawl 1 swing, adopt the assembly mode of sliding hinge between push rod 2 and the tail end of pawl 1, namely set up a pin at the front end of push rod 2 fixedly, set up a waist shape hole at the tail end of pawl 1, inlay the waist shape hole in pawl 1 with the pin slip on the push rod 2, in practical application, still can change the position of waist shape hole and the pin that the slip hinge set up between push rod and pawl and set up.
A push rod spring 8 is provided between the push rod 2 and the push rod holder plate 3, holding the pawl in engagement with the ratchet teeth. Specifically be equipped with along length direction's empty slot on push rod 2, push rod spring 8 fills in this empty slot, still has inlayed the spring positioning arch on push rod mounting panel 3 in this empty slot, and push rod spring 8 compression back both ends are connected with empty slot tip and spring positioning arch respectively, and the push rod spring 8 of packing promotes the push rod outwards, with pawl and ratchet interlock.
When the push rod 2 is pressed inwards by external force, the elasticity of the push rod spring 8 is overcome, the linear motion of the push rod 2 is changed into circumferential swing of the pawl 1, the pawl end is separated from the ratchet wheel outwards under the action of the lever, the ratchet wheel and the gear coaxially connected with the ratchet wheel are in a free rotation state, and the left baffle 7 and the right baffle 11 reset towards the middle under the action of the reset tension spring 4. When the external force for pressing the push rod is withdrawn, under the action force of the push rod spring 8, the push rod 2 is reset, the pawl 1 is driven to swing back and be meshed with the ratchet, at the moment, the left baffle plate 7 and the right baffle plate 11 can be pushed outwards in a one-way mode, and the left baffle plate 7 and the right baffle plate 11 cannot be reset under the action of the reset tension spring 8 due to one-way locking of the ratchet and the pawl.
The push rod support plate 3 is fixedly arranged on the bottom surface of the main frame 6 of the locking mechanism, is coaxially connected with a gear of the ratchet-gear set 9 and a ratchet wheel, and extends into the main frame 6 through the push rod support plate 3 to be matched with the synchronous gear rack baffle assembly of the locking mechanism. The synchronous gear rack baffle assembly comprises a left baffle 7, a right baffle 11, a left rack 5 and a right rack 10, wherein the left baffle 7 and the right baffle 11 are arranged on the front surface of the main frame 6 in parallel, and are assembled in a mutually opposite sliding way, namely, the distance between two groups of baffles is adjusted through the mutually opposite sliding way, and parallel channels between the two groups of baffles are limiting channels of media. The left rack 5 and the right rack 10 are respectively and fixedly connected with the bottoms of the left baffle 7 and the right baffle 11, the arrangement direction of the racks is respectively parallel to the sliding direction of the baffles, the left rack 5 and the right rack 10 are arranged in parallel, the racks are arranged opposite to each other and are respectively meshed with the two sides of the gear of the ratchet-gear set 9, and the two groups of racks are symmetrically arranged by taking the circle center of the gear as a center point. The gears rotate in any direction, so that the two groups of racks can be driven to linearly slide in opposite directions, and finally the baffle 7 and the right baffle 11 are driven to slide in opposite directions or back to back.
The right rack 10 connected with the right baffle 11 is connected with the main frame 6 through a stretched reset tension spring 4, and after the pawl is separated from the ratchet wheel, the two groups of racks and the two groups of baffles are driven to approach to the middle for reset through the tension of the reset tension spring 4 and the transmission of the gear rack.
In this embodiment, the left rack 5 and the right rack 10 are respectively and rigidly connected with the left baffle 7 and the right baffle 11, then the left rack 5 and the right rack 10 are slidably embedded in a chute on the main frame 6 to be engaged with a gear, the left rack 5 and the right rack 10 can only drive the left baffle 7 and the right baffle 11 to move left and right by the structural limitation of the main frame 6, and the left rack 5 and the right rack 10 are engaged with the gear of the ratchet-gear set 9, so that the left rack 5 and the right rack 10 can only move reversely and synchronously left and right. The left baffle 7 and the right baffle 11 are respectively fixedly installed with the left rack 5 and the right rack 10, and the reset tension spring 4 is connected with the right rack 10 and the main frame 6, so that the right rack 10 is constantly subjected to left tension. Therefore, under the condition that no external force acts on the push rod 2, the left baffle 7 and the right baffle 11 can be stirred to synchronously move outwards, as shown in fig. 2, the left baffle 7 and the right baffle 11 are mutually far away, the reset tension spring 4 is lengthened, in the process, the rack drives the gear to rotate, the gear drives the ratchet to rotate unidirectionally, the ratchet-gear set 9 cannot rotate reversely under the action of the pawl 1, and the reset tension spring 4 cannot pull the right rack 10 to reset, so that the positions of the left baffle 7 and the right baffle 11 are fixed; after the medium is placed in the gap between the left baffle 7 and the right baffle 11, the external force acts on the push rod 2, the pawl 1 is separated from the ratchet wheel of the ratchet wheel-gear set 9, the ratchet wheel-gear set 9 can rotate freely, the left baffle 7 and the right baffle 11 move inwards under the transmission action of the reset tension spring 4 and the gear rack, the left baffle 7 and the right baffle 11 are close to each other, as shown in fig. 3, the left baffle 7 and the right baffle 11 stop at two sides of the medium, and accurate limiting of the medium is realized.
