See also Fig. 2, another kind of both arms gear, tooth bar engagement link gear, be provided with major axis 23 interlocks between two gears 21, two handles 24 are separately fixed on two gears 21, the dual-side of drag hook plate 25 respectively correspondence be provided with 22, two gears of tooth bar 21 and mesh respectively with the tooth bar 22 that drag hook plate 25 is provided with.When handle 24 moves upward, gear 21 clockwise rotates, stirring tooth bar 22 simultaneously moves with drag hook plate 25 is parallel downwards, both arms gear, tooth bar engagement link gear, because gear 21 is that vertical engagement is moved with tooth bar 22, the stroke height of gear 21 is restricted, and therefore in use function is restricted.
Summary of the invention
The purpose of this utility model is that the glue ring open loop mechanism that will solve existing puncher bookbinding structure exists the single armed unreasonable structure, the operation effort, and provide a kind of use labour-saving puncher both hands synchronous drag hook mechanism.
The purpose of this utility model is achieved in that a kind of both hands of puncher synchronous drag hook mechanism, comprise a baffle ring frame, are located at the drag hook plate under the baffle ring frame, gear, the handle that correspondence is located at drag hook plate both sides; Be characterized in that the bottom of described baffle ring frame both sides vertically is provided with protruding pin respectively; Described drag hook plate both sides are provided with open slot, and the outer side edges of groove is respectively equipped with tooth bar; Also comprise a connecting rod, two rocking arms; Described connecting rod two ends are connected with an end of two rocking arms respectively; The other end of described handle, gear and rocking arm is successively by the installing hole formation gear assembly that is connected as a single entity; The gear of two gear assemblies respectively with the tooth bar engagement of the open slot both sides of drag hook plate; Open slot, gear center hole that the protruding pin of baffle ring frame bottom passes the drag hook plate flexibly connect.
The both hands of above-mentioned puncher are synchronous drag hook mechanism, and wherein, described gear rotational plane is parallel with the drag hook board plane.
The both hands of above-mentioned puncher are synchronous drag hook mechanism, and wherein, described two rocking arm axis equate with the angle α of the direction of motion.
The both hands of above-mentioned puncher are synchronous drag hook mechanism, and wherein, the radius of described two rocking arms equates.
The both hands of above-mentioned puncher wherein, are characterised in that synchronous drag hook mechanism: connected by connecting rod between described two rocking arms.
The utility model compared with prior art, has significant advantage and effect owing to adopt above technical scheme:
The utility model meshes owing to the tooth bar that is provided with in drag hook plate both sides and with the gear plane, the two rocking arm radiuses that are provided with equate, the connecting rod that is provided with in mechanism connects the synchronous rocker of two gear assemblies and rotates, two rocking arm axis equate that with the angle α of the direction of motion when the pulling handle, the gear rotation is stirred the drag hook plate and moved up and down, coefficient of friction is little, speed change is convenient, and is laborsaving when dual-handle is manipulated, convenient, rotates flexibly.
Description of drawings
Concrete structure of the present utility model is further provided by following examples and accompanying drawing thereof.
Fig. 1 is the single-arm lever toggle mechanism structural representation of existing puncher.
Fig. 2 is both arms gear, the tooth bar engagement link gear structural representation of existing puncher.
Fig. 3 is the synchronous drag hook mechanism structure schematic diagram of both hands handle of the utility model puncher.
The specific embodiment
See also Fig. 3, the both hands of the new puncher of this practicality comprise drag hook mechanism synchronously: a baffle ring frame 31, be located at gear 33, handle 34 that a drag hook plate 32, correspondence under the baffle ring frame is located at drag hook plate 32 both sides; The bottom of baffle ring frame 31 both sides vertically is provided with protruding pin 37 respectively; Described drag hook plate 32 both sides are provided with open slot 321, and the outer side edges of groove is respectively equipped with tooth bar 322; Also comprise 35, two rocking arms 36 of a connecting rod; The radius of making two rocking arms equates that connecting rod 35 two ends are connected with an end of two rocking arms 36 respectively; The other end of handle 34, gear 33 and rocking arm 36 is connected as a single entity by installing hole successively and constitutes gear assembly A; The gear 33 of two gear assembly A respectively with tooth bar 322 engagements of the open slot both sides of drag hook plate 32; Open slot 321, gear 33 centre bores that the protruding pin 37 of baffle ring frame 32 bottoms passes drag hook plate 32 flexibly connect.
When handle 34 upwards rotates, gear 33 is stirred tooth bar 22 moves up drag hook plate 32 simultaneously, two rocking arms 36 of two gear assembly A connect connecting rod 35 and do to rotate synchronously, when two gears 33 rotate, gear 33 rotational planes and drag hook plate 32 plane parallel, two rocking arm axis equate that with the angle α of the direction of motion coefficient of friction is little, and speed change is convenient; Because connected by connecting rod between two rocking arms, dual-handle is easy to operate, use laborsavingly, rotate flexible.
In sum, the utility model reasonable in design, novelty connect two gear assemblies and rotate synchronously owing to be provided with connecting rod in mechanism, and coefficient of friction is little, and speed change is convenient, and be laborsaving when dual-handle is manipulated, convenient, rotates flexibly.
