There is sufficiently long range to fall under bracket, support rod is made to change its range of extension in the larger context, is applicable in more size ranges
Brake-shoe use.Further, the outer diameter of the spiral shell axle portion is consistent with the outer diameter in optical axis portion, and spiral shell axle portion is enable to pass through bracket
On the second through-hole, adjust the folding of support rod.
Fig. 1-3,5 and 6 are please referred to, more specifically, the horizontal centre of the handle jacket 1 is equipped with first through hole 1a, it is described
First through hole 1a is equipped with internal screw thread, is spirally connected with the spiral shell axle portion 31 of pull rod 3；The horizontal centre of the bracket 2 is equipped with the second through-hole 2a,
It is adapted with the optical axis portion 32 of pull rod 3；The first through hole 1a is located at the surface of the second through-hole 2a.First through hole and pull rod spiral shell
It connects, facilitates the fixation of position；Second through-hole is unthreaded hole, is more convenient the change in optical axis portion and its position, reduces friction and does not allow
Easily loosen.
Specifically, the bracket 2 includes first connecting rod 21 and the second connecting rod 22, and the second through-hole 2a setting is the
In one connecting rod 21, the both ends of first connecting rod 21 further respectively have the third through-hole 2b in horizontal direction；Second connection
Bar 22 is equipped with two, and the upper end is connected on first connecting rod 21 vertically respectively, and lower end is equipped with the fourth hole in horizontal direction
2c, and two second connecting rods 22 are relative to 3 bilateral symmetry of pull rod.The support rod passes through the second connection from inside to outside respectively
Bar is connected with first connecting rod, improves the stability of its connection, and two second connecting rods are symmetrical arranged, and makes connected to it two
A support rod receives pull rod and imposes identical power, and then makes the both sides uniform force of brake-shoe, struts identical distance.Third is logical
Hole and fourth hole are respectively arranged at the lower end of first connecting rod and the second connecting rod, and first connecting rod and the second connecting rod
Lower end is cambered surface, and the lower end of first connecting rod and the second connecting rod is too long and influence support rod and brake-shoe when avoiding work
Contact surface；And the lower end of first connecting rod and the second connecting rod is cambered surface, it is not easy to scratch other parts.
Further, the third through-hole 2b and fourth hole 2c is unthreaded hole, and central shaft is located at same level
On face.The setting of unthreaded hole is conducive to the movement of support rod, reduces friction, laborsaving saving of labor；Guarantee in third through-hole and fourth hole
Mandrel makes support rod be maintained at horizontal state in same level, increases effective contact surface with brake-shoe.
Specifically, the support rod 4 includes slanted pushing rod 41 and barrel axis 42, and slanted pushing rod 41 is fixed on fourth hole 2c,
One end is inclined-plane compatible with the side of sliding part 33 of pull rod 3, is abutted with the sliding part 33 of pull rod, the other end protrudes into barrel
The inside of axis 42；Barrel axis 42 is fixed on third through-hole 2b, and fixing end is socketed on slanted pushing rod 41, free end and brake-shoe
A is abutted.In practical application, the brake-shoe of different size can be adapted to by adjusting the bonding length of slanted pushing rod and barrel axis
It needs, the third through-hole is adapted with barrel axis, and fourth hole is adapted with slanted pushing rod.
Further, the slanted pushing rod 41 is spirally connected with barrel axis 42.Barrel axis is equipped with the outer spiral shell on internal screw thread, with slanted pushing rod
Line adaptation, specifically, the barrel axis upper screwed hole is blind hole, the depth in hole so that barrel axis it is close with the second connecting rod
One end does not contact subject to the second connecting rod.Slanted pushing rod is connect by the way of screw thread with barrel axis, is unclamped and is tightened conveniently, and
Positioning is firm, it is not easy to loosen.
In a kind of embodiment, flexible gasket 43 is also connected on the free end that the barrel axis 42 is abutted with brake-shoe A.
The flexible gasket is selected rubber or high polymer composite material etc. to have certain elastically-deformable material and is made, make support rod with
Certain buffering is generated between brake-shoe, improves the compactness between brake-shoe.
As shown in Figure 4, it is preferable that the contact surface of the flexible gasket 43 and brake-shoe A is serrated.Improve contact surface
Roughness, increasing friction force improve contact stabilization.In practical application, which can also be other and is capable of increasing friction
The shape of power, such as surface increase salient point.It is detachably connected between the flexible gasket and barrel axis, it can after flexible gasket abrasion
To be convenient for changing.
A kind of assembly and disassembly methods of drum brake brake-shoe, use above-mentioned attaching/detaching apparatus, comprising: set the attaching/detaching apparatus
In in brake-shoe A, the length of two support rods 4 is adjusted by the barrel axis of rotating rod two sides respectively, makes two support rods
Length is consistent, and the serrated face of the flexible gasket on support rod 4 is abutted with the inner surface of brake-shoe A；Rotational handle sleeve 1 makes
Pull rod rises, so that support rod 4 be driven to flex outward, so that the spacing on the both sides brake-shoe A is expanded 2-3mm, brake-shoe is made to overcome bullet
Then spring restoring force carries out the dismounting of brake-shoe A；The difficulty for reducing dismounting improves the efficiency of dismounting.
