Fig. 2 is the A-A of Fig. 1 of the present utility model to cutaway view Amplified image.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only in order to explain The utility model, is not used to limit the utility model.

Refer to Fig. 1, Fig. 2, embodiment of the present utility model provides a kind of anti-slip leaf spring, including,

Multiple reeds 1, multiple described reeds 1 are cascading from the bottom to top and length is gradually increased, each described spring It is provided with fixing hole in the middle part of piece 1；

The centre bolt 2 sequentially passing through the fixing hole of multiple described reeds 1 and multiple described reeds 1 being connected；

It is sheathed on the multiple clamps 3 on adjacent multiple described reed 1, each described clamp 3 all includes pushing against in described in one First clamping part 31 of reed 1 lower surface, upwardly extended formed two second folders respectively by described first clamping part 31 two ends Hold portion 32, the fastening bolt 33 of two described second clamping part 32 upper ends of connection；And

Multiple pads 4, each described pad 4 is all equipped between two neighboring described reed 1；

Wherein, described first clamping part 31 is provided with raised 34, described reed 1 is provided with and matches with described raised 34 The groove 11 closing, described raised 34 can coordinate and are placed in described groove 11.

Specifically, the reed 1 of the present embodiment may be configured as eight, and clamp 3 is set to four, wherein leaf spring upper end Adjacent three reeds 1 to pass through two clamps 3 fixing, and adjacent six reeds 1 of leaf spring upper end are also by two clamps 3 Fixing, near the end face setting of one of reed 1 when clamp 3 is fixing, because clamp 3 is disposed therein one correspondingly The two ends of reed 1, therefore clamp 3 is typically even number, and in order to ensure the harmony of power during clamp 3 fixation, it is located therein one The axis of two clamps 3 centre bolt 2 relatively at individual reed 1 two ends is symmetrical arranged.

When clamp 3 is installed, the projection 34 in clamp 3 can be correspondingly arranged in the groove 11 on reed 1, thus ensureing to press from both sides Hoop 3 is preferably fixed on the end of corresponding reed 1.And in order to ensure raised 34 with the stability of reed 1 cooperation and equal Weighing apparatus property, described raised 34 set at least to two, and in order to reduce difficulty of processing, the present embodiment preferably sets in each clamp 3 Put two projections 34, two projections 34 are uniformly arranged along described first clamping part 31 length direction, the setting of corresponding reed 1 one end There are two grooves 11, groove 11 can be provided only on the reed 1 matching with clamp 4, also can be all provided with each spring 1 Put the installation of the diverse location in order to clamp 4 for the groove 11, the present embodiment is preferably setting on the corresponding reed of clamp 41 Groove 11.Wherein, the formation of groove 11 and projection 34 can be arranged as required to, and may be configured as cylindric, rectangle or hemispherical, this Embodiment be preferably arranged to spherical, its can be easy to dock.

Because clamp 3 lower end is fixing relative to reed 1, therefore abut and send out between the reed 1 of fastening bolt 33 and fastening bolt 33 It is also easy to produce larger frictional force during raw relative motion, or even damages fastening bolt 33, lead to the fastening force of clamp 3 to reduce or lose Fastening effect, damages fastening bolt 33 in order to avoid when fastening bolt 33 and reed 1 relative motion, fastens spiral shell described in the present embodiment Sleeve 35 is arranged with bolt 33, described sleeve pipe 35 is rotatably connected with described fastening bolt 33, thus by fastening bolt 33 with Sliding friction between reed 1 is converted to the rolling friction between sleeve pipe 35 and reed 1, reduces and avoids while coefficient of friction Fastening bolt 33 directly rubs and reed 1 between, and it is conducive to extending the service life of clamp 3.And, sleeve pipe 35 Setting also can reduce the noise that between fastening bolt 33 and reed 1, sliding friction produces.

Between two neighboring reed 1, setting pad 4 can preferably reduce making an uproar of two neighboring reed 1 relative motion generation Sound, but when there is relative motion between reed 1, pad 4 easily relative reed 1 generation sidesway, and slowly from two reeds 1 it Between depart from, in order to avoid the sidesway of pad 4, each described reed 1 lower surface of the present embodiment is provided with cloth along its length The fixing groove 12 put, each described pad 4 is provided with the raised line 5 being matched with the fixing groove 12 on described reed 1, described Raised line 5 can coordinate and is placed in described fixing groove 12, so that pad 4 reed 1 relatively is fixing, it is to avoid the sending out of pad 4 sidesway Raw.

Compared with prior art, the utility model passes through to arrange raised 34 on the first clamping part 31, and is corresponding to therewith Reed 1 on setting groove 11 so that clamp 3 can relatively this corresponding reed 1 fixing, it is to avoid two neighboring reed 1 is transported relatively When dynamic, clamp 3 is slided, and which raises stationarity and the stability of clamp 3.

The above specific embodiment of the present utility model, does not constitute the restriction to the utility model protection domain. Any according to technology design of the present utility model made various other corresponding change with deformation, should be included in this practicality In new scope of the claims.
