Description

4. Description of creation (1) [Technical field to which the new type belongs] This creation is about a rare removed component that is not easy to crack and has a better structure than the hand structure, especially a good one. People's use the brother's ratchet wrench structure to change [prior art] Press, the conventionally known spines are buckled 1 8 3 and US patent 5 q 2 such as Taiwan Patent Bulletin No. 4 4 3 "3 4 9 9 0, 6 35 36 : J 7, 5 9 7 9 2 7 4, 446530, and 6 591713, 6382〇5; 1, 6 are provided with a number of sixteen on the head of a wrench, the structure is mainly the first tank There is a toilet on the side, 9 can be accommodated by a ratchet, and it can be accommodated by a piece, and a brake unit ratchet can be coupled in the second receiving slot of the brake element ^, and generally = 1 1 sex body can push it to use, as opposed to the elastic body _ = ratchet is made as a card engine thin, and is opposite to the ratchet ^ 5 to avoid the narrowing of the area of the apex and ratchet peripheral teeth;: = = There are several clamping teeth, which can be arranged in a -arc surface, and each-;: The clamping teeth also follow the arc-shaped bear of the ratchet. The clamping teeth are in complete engagement with the occlusal teeth. Ξ 2 2 = ::: Bridge :: Backhand: Its latching tooth system and ratchet say 1, / — the upper A 丨 like resentment, that is, each degree of meshing is the same, Γ 二 Γ: completely under the pressure from the teeth The same, but, the 70-phase street is set to gradually reduce the area at one end of the elastomer. Ί ,: owing :: It must conform to the shape of the second volume. The opposite end gradually decreases

Page 5 1. Creation instructions (2): So in the case where each of the clamping teeth is subject to the same pressure, and the moving parts abut against the elastic body, the L is prone to chipping and breaking. However, the collapse of the second crane will cause the ratchet of the ratchet to be too strong, and the second piece of the ratchet may be unable to rotate. Therefore, Hai Yu: between the walls of the groove, it has existed for a long time. The ratchet wrench structure of the brake element is easy to collapse, which is a serious disadvantage. The reason that the service life is not long is that the creator is thinking about the many shortcomings caused by the above-mentioned imperfections. 1 Use a ratchet wrench to design the structure, and actively study the way of improvement. Period :: Problems. And the in-depth design of this creation. Developed by trying to improve the trial of Chang 4 [New content] Chang = = Kind of "She has a more----slot structure improvement, including-the wrench head slot" The second slot 2 ：: The side is provided with a second and first communicating groove communicating with it, "y-guide slope; a ratchet system can be arranged on the ratchet and a ratchet ring is provided with a plurality of engaging teeth on the peripheral ring of the ratchet. The components are arranged in the second = two parts for screwing or sleeve embedding; a braking opposite side is provided with a top 2 " middle 'and one side is provided with a plurality of clamping teeth, and the surface, and the The braking element surface and an inclined surface. The inclined surface is arranged next to the guide inclined teeth. The inclined surface is arranged in a fox and gradually decreases along the inclined surface from the abutting surface. The engagement area of the card follows the braking surface and causes each of the engaging teeth. The reduction of the sprocket that engages the ratchet teeth is reduced; an elastic system abuts on the 921230 ratchet brake. Ptd page 6 M249766 4. Creation instructions (3) The top abutment surface on one side of the braking element; a buckle system can It is used for sealing the ratchet wheel in the first receiving groove. In this way, each of the engaging teeth and the ratchet wheel on the braking element can be used. The structure design of the degree of tooth engagement of the tooth decreases as the braking element shrinks, so that it is not easy to crack and has a long life. [Embodiment] Please refer to the first to fifth figures, which is a kind of The improved structure of the ratchet wrench includes: a first receiving slot (1 0) is arranged on the wrench head (1), and a second receiving slot is provided on the side of the first receiving slot (10); (11), and one side of the second receiving groove is provided with a guide inclined surface (1 2), and the guide inclined surface (1 2) is tangent to the wall edge of the first receiving groove (1 0); a ratchet ( 2) is provided in the first receiving groove (1 0) and can be rotated in the first receiving groove (1 0), and a plurality of occlusal teeth (2) are provided on the periphery of the ratchet (2). 0), and the ratchet wheel (2) is further provided with a fitting portion (2 1) for a screw fitting, and the fitting portion (2 1) may be a polygonal groove; a braking element ( 3) is disposed in the second receiving groove (1 1), and one side of the braking element (3) is provided with a plurality of clamping teeth (3 0), and is opposite to the clamping teeth (3 0) ) On the other two sides The abutting surface (3 1) and an inclined surface (32), the inclined surface (32) is abutted on the guide inclined surface (1 2), and can slide along the guide inclined surface (1 2), and the braking element The shape of (3) is a top-to-face (3)

M249766 Study and creation instructions (5) Please refer to the respective clamping teeth (3 area, the closer it is to the top tooth (2 0), the closer it is to the teeth The beveled teeth of the bevel (the smaller the pressure of 3, one of (3 1) can be due to the situation, the largest of the teeth (ratchet) (the mesh of the bite volume (21 closed sleeve and bear on the same patent end Therefore, the advantages are: the creator 3) 2) the tooth (2 is reduced and the other is created), the application of the above-mentioned products requires 5 maps and 0) and the brake element surface (3 surface (32 0)), so That is to say, due to the pressure on the end, it can be shown by the end of the ratchet (the product of (3 1) is larger) that the tip can be made smaller and sharper than the occlusal teeth of the production system 2). ) The volume of the shrink card teeth (30, so the bearing is the top contact surface (the structural strength due to the coupling area of the moving element (3), making it difficult to use the life of the moving element ((20) small And gradually), because its pressure is 3 1), it is too weak relative to the top to cause collapse, this is 3) The meshing is reduced, the occlusion is larger, and when the opposite end bears the abutment, it also breaks the original creation.

The important design idea is that the card of the braking element (3) is arranged in an arc surface, and the diameter of this arc surface can be slightly larger than the diameter, so that the engagement area of each clamping tooth (30) and the ratchet wheel (2) 0) That is, as the braking element decreases. , J) One embodiment, the ratchet wheel (2) is provided with a fitting part (21) that can be a protruding sleeve end.
