Abstract

A ratchet bar push structure of grease gun includes a gun body and a grease storage section. A ratchet bar is slidably disposed in the gun body and reciprocally movable as a piston to dispense grease supplied by the grease storage section out of the gun body. A pad section is movably disposed between the ratchet bar and a push member for pushing the ratchet bar as a force transmission unit. A user can change the position of the pad section to control whether an action force of the push member is transmitted to the ratchet bar. When the pad section is positioned in a padded position, the external force is applied to the ratchet bar via the pad section to push the ratchet bar. When positioned in a released position, the force transmission path is interrupted, whereby the ratchet bar will not be pushed by the push member.

New description: [New technical field] This creation is related to the butter applicator, especially the spine push structure of butter. [Prior Art] •- Press ^ to use the butter to steal the yellow secret on the specific work, according to the effect of skidding or rust prevention, etc., the technical shooter is a general, and the seam oil is only lost. The technology of Butter Lu is not in line with the actual operation requirements. Therefore, it is like the US Public Publication No. 2009/0272762M and China's M39 Cong No. Patent disclosed in the double flow butter robbing technique. According to the side butter flow output mode of the whistling high pressure reduction or the health level, in response to the actual environmental requirements when the butter is applied. In the further step, the technology of the double-flow round-off is based on the patent-opening case. The main reason is that the piston of the oil-sucking rod is pushed by a rod of different sizes to make the butter in the piston chamber. She turned to the private and determined amount of talent (10). The thief was exported to the snail of the small rod and turned to the high-pressure and low-flow mode. From the structural point of view, the patents were different. The fuel-pumping rod is read and subjected to the reciprocating piston action by the user's force, and when the yellow--the back pressure caused by the application is greater than the output pressure of the large-rod-pushing oil-buckle rod, the large-rod diameter pushes the oil spine# The promoted butter is returned to the storage of the butter by the shunting flow channel, and only the small rod #A spine; the butter pushed by the extract can be exported to the outside. Butter application for different flow output. The technical content of the backflow of the butter by the structure of the split flow channel can achieve the effect of the butter having the output of the double flow #, but in terms of its structure, it is necessary to push the piston of the oil ratchet 3 M414536. - a ratchet (5 〇) is coaxially slidably disposed in the first piston chamber (42), and is configured to reciprocate the piston, having a main shaft (9) disposed in the first piston chamber (5) The rod is in the same shape as the inner diameter of the first piston chamber (42), and the cross section is a non-circular rectangular end shaft (5). The stone of the main shaft (51) is bribed, _ Connecting the main shaft (9) to the stem of the first piston chamber () and making the outer diameter of the end shaft (52) smaller than the diameter of the main shaft (5). The second ratchet (60) is coaxially slidably disposed in the second piston chamber (43), and the piston can be reciprocated therein, and the rod is extinguished. The second piston chamber (43) is external. The pushing member (70) has an end portion (f), and a sliding portion (72) is connected at one end to the end portion (6), and the other end is connected to the first-spindle rod ( 50) one end of the shaft is coaxially slid, so that the first ratchet (10) a reciprocating telescopic sliding movement with respect to the end portion (71); and further, the end portion (71) is substantially plate-shaped and perpendicular to the second ratchet rod (6〇) And being connected to the first-spindle (5Q) by the sliding portion (72), whereby the end portion (71) is pressed by the pressing handle (21) of the stealing body (10) Applying a force to cause each of the ratchets (5〇) (6〇) to be displaced by force; the sliding portion (72) has a sliding bar (721) fixed to the end by the shaft end On the portion (71), a sliding hole (722) extends from the free end of the end shaft (52) to a proper depth into the main shaft (51) and is coaxial with the sliding rod (721). The pad portion (80) has a block body (81) of a suitable thickness, and a side block surface is attached to the plate surface of the end portion (71) and pivotally connected to the slide bar (721). In combination with '俾', the block (4) is pivoted between a padding and a release position by the shaft of the slider (721), and a shape is broken with the end rod 6 M414536 (52) a groove-shaped accommodating space (82) having a complementary surface shape extending from the other side of the block body (81) to form an 'according to this' (81) when the release position is such that the opening of the receiving space (82) and the rod end of the end shaft (52) are opposite each other and complement each other so that the end shaft (52) is self-contained The opening of the receiving space (82) slides into the receiving space (82), and when the block (81) is located in the padding position, the receiving space (82) is opened and the end shaft (52) The rod end shape is in a staggered state, so that the end shaft (52) cannot protrude into the accommodating space (82), and the rod end end surface abuts against the other side block of the block body (81) On the surface. By virtue of the composition of the above components, the butter grabbing push structure (10) is controlled by the user's choice, and has the effect of dual flow output, in particular, when the application of butter is required to be large, The entire portion (80) is positioned at the mating position such that the body (four) is sandwiched between the rod end of the end shaft (52) and the end portion (71). When the pressing handle (21) is applied, the end portion (71) is connected to the second ratchet rod by the gj of the belt, and the piston is moved by the second piston chamber (43). (8〇) exerting a force on the end shaft (52) to drive the first ratchet (50) to move the piston in the first piston chamber (42), so that it will be located in each of the first, The butter in the φ-piston chamber (42) (43) is pushed out simultaneously to achieve a large amount of output of the butter. When #奶油之兰 needs to be a small amount, only S is transferred from the external financial index to the body (81), so that it is rotated from the position of the person to the release position, and the user passes the pressure handle (9). The force applied 'only has to push the second ratchet (6 〇) fixed to the end (f) to cause a smaller flow of butter, and in terms of the first ratchet (5 〇) Since one end of the shaft does not abut against the end portion (71), the longitudinal end portion (71) is displaced by the pressing of the pressing handle (21), and only the end shaft can be changed ( 52) A depth that protrudes into the accommodation space (82), and fails to push the first - ratchet 7 (50) to generate an axially reciprocating piston action. In this way, the user can control the output flow of the butter according to the actual needs, and in contrast to the conventional tearing (4), the scale of the secret material is promoted by the money (10), the money is the 'out of time' of the butter, and the - The ratchet (5〇) exerts a force to displace it, so it is more labor-saving in use, and it is not necessary to provide a shunting flow path as in the prior art for the assembly process. In fact, it is also easier. M414536 [Simple Description of the Drawings] The first drawing is a perspective view of a preferred embodiment.
