Abstract
The utility model relates to a force-increasing toggle rod type mechanical pressing clamp which is suitable for cable construction and is a manual tool for the cold press joint of cable splices. The force-increasing toggle rod type mechanical pressing clamp is composed of a clamp body, a bracket, a female mold, a male mold, and a handle, a ratchet pawl, a ratchet wheel, a cam and a small spring which are arranged in a first level force-increasing mechanism, and a rolling bearing, a short toggle rod, a long toggle rod, a pin shaft, a clamp head and a big spring which are arranged in a second level force-increasing mechanism, etc. The outer circle of the female mold is processed into various grooves in the shapes of cable pressed joint specifications, and the outer circle of the female mold can be rotated. The utility model has the advantages that the force-increasing rate is large when the utility model is used for compression joint, the operation is portable and labor-saving, the female mold does not need to be replaced and can momentarily and automatically return, and the utility model is labor-saving and time-saving.
Description
The utility model is applicable in the cable construction, a kind of hand-operated tools that cable connector is colded pressing and connected.
Mechanical pressing pliers of the prior art, most structure adopts passes through handle, drive tooth bar or (ratchet), promote gear (or ratchet), drive eccentric wheel again, promote the purpose that pressing mold reaches crimping then, also useful rotary screw rod, drive nut, activation lever reinforcement carry out crimping work.Therefore this two classes mechanical pressing pliers all has only the one-level force-increasing mechanism, and it is limited to expand force rate, and labour intensity is big when making operation, and former needs often to change, and work is inconvenient.
The purpose of this utility model is: it is big, easy to operate to make a kind of expansion force rate, and handling ease has the mechanical pressing pliers of two-stage force-increasing mechanism.
Toggle link boosting-type mechanical pressing pliers of the present utility model, by vice body, the short toggle link of rolling bearing in handle in support, former, formpiston and the first order force-increasing mechanism, ratchet, ratchet, cam, little spring and the second level force-increasing mechanism, long toggle link, bearing pin, binding clip, big spring etc. are partly formed.
Former is a garden shape, and its center is rack-mount with bearing pin, and is rotatable.The Baltimore groove of various cable crimping specifications is processed in the outer garden of former.
The utility model compared with prior art, it is big that its advantage is to expand force rate, operates lightly, can alleviate operator's labour intensity, and processing technology is simple, formpiston can instantaneous self-return, and is time saving and energy saving.
Below in conjunction with accompanying drawing embodiment is described:
See the handle (1) among Fig. 1, it strikes out channel steel shape by general steel plate, and an end of two ratchets (2) uses pin (3) to be installed on handle (1) and the vice body (5) respectively.The other end contacts with ratchet (4).When carrying out crimping work, shake handle (1), drive ratchet (2), driving pawl (4) is done the counter-clockwise direction rotation then.Ratchet (4) and cam (6) are with being contained on the bearing pin (7).The two ends of bearing pin (7) are installed in the inner chamber of the vice body (5) with box-formed shape, and ratchet (4) is that the pin (8) by 2 φ 4mm is fixed on the cam (6).When ratchet (4) rotates, drive cam (6) to the anticlockwise rotation, this is a first order reinforcement.Because of cam (6) contacts with rolling bearing (9), when cam (6) rotates, drive rolling bearing (9) and rotate clockwise.Because of rolling bearing (9) and two short toggle links (10) and two long toggle links (11) all are contained on the bearing pin (12), and be contained in the both sides of rolling bearing (9) respectively, be symmetrically distributed.The other end of short toggle link (10) is to be installed on support (14) and the vice body (5) with bearing pin (13).One end of long toggle link (11) and binding clip (15) are with being contained on the bearing pin (16), and the other end of long toggle link (11) is connected with big spring (17), and the middle part of binding clip (15) is installed on vice body (5) and the support (14) with bearing pin (18).When cam (6) rotates, promoting rolling bearing (9) rotates, and bearing pin (12) is moved to the right, thereby short toggle link (10) is pressed clockwise around bearing pin (13) to rotate, an end that also promotes long toggle link (11), bearing pin (16) and binding clip (15) moves upward around bearing pin (18), the other end of binding clip (15) is to pressing down, and this is a second level reinforcement.To the end of the binding clip that presses down (15) formpiston (19) is being housed, former (20) is contained on the support (14) with bearing pin (21).When formpiston (19) when pressing down, and be crimped part in the groove of former (20) and contact, treat that cam (6) contacts with rolling bearing (9) and when peaking, just finished crimping work.At this moment because the effect of big spring (17) retracts long toggle link (11), make the instantaneous self-return of formpiston.One end of little spring (22) is contained on the vice body (5), and the other end is connected with handle (1), and its effect is to make handle (1) energy self-return.At the two ends of all bearing pins, circlip for shaft all is housed, be used for preventing that the string of bearing pin is moving.
