Abstract
The utility model discloses a clamp type flower-drum fixer, which comprises a case and a wheel group, wherein the case is at least partially sheathed on the wheel group; the fixer also further comprises one or more than one elastic element; and the elastic element is sheathed on the outer surface of the wheel group, and is positioned between the case and the wheel group. During assembling, the elastic element is deformed through being simultaneously pressed by the case and the wheel group, and produces counterforce to the case and the wheel group to fill gaps between the case and the wheel group, so the case and the wheel group are tight combined, and the swinging of the case is avoided. Because the utility model eliminates the gaps during assembling, the beating produced during assembling the case and the wheel group is reduced. Thereby, after the adoption of the structure, the beating during assembling can be reduced to realize the goals of easy assembly, easy replacement and low cost.

The specific embodiment
Below in conjunction with drawings and embodiments the utility model is further specified.
As shown in Figure 1, the utility model discloses a kind of cassette flower-drum anchor fitting, and described in the present embodiment anchor fitting mainly comprises cassette flower drum shell 1, ratchet group 2 and elastic element, wherein:
Be provided with other assembly in the above-mentioned flower drum shell 1, this other assembly comprises the stacked successively car heart 41, two nuts 421,422, washer 43, sleeve pipe 44, beautiful signature 451,452, oil sealing 46, watertight cover 47, steel ball 481,482 and pearl bowl 49.
Comprise stacked successively neutron 21, oil sealing 22, steel ball 231,232, ratchet pawl 24, latch spring 25 in the ratchet group 2, adjust washer 26, breach pearl bowl 27, sleeve 28 and plane oil sealing 29.
In the present embodiment, its elastic element is an O type circle 3, and it is to utilize elastomeric material as forming with the mold pressing of oil resistant rubber, and this O type circle 3 can utilize poly-propionic ester rubber, silaatic, viton, polytetrafluoroethylene or government rubber to make.Wherein, the O type circle cost that utilizes government rubber to make is minimum.O type circle 3 is behind bearing load, and elastic element deforms, stored energy; After load alleviated or eliminates, elastic element can release energy, and recovered virgin state.Therefore, it has elasticity, and it can make flower drum shell 1 and ratchet group 2 closely cooperate.Above-mentioned O type circle 3 comprises two O type circles 31,32.
With reference to shown in Figure 2, be processed with internal diameter 11 and interior plum blossom tooth 12 in the flower-drum housing 1.
Sheathed more stable for two O type circles 31,32 making O type circle 3 and above-mentioned neutron 21, on outer end diameter 211 diametric(al)s of the neutron 21 of above-mentioned ratchet group 3, be provided with two annular grooves 212,213, the outside face of neutron 21 also is provided with plum blossom tooth 214.
During assembling, two O type circles 31,32 are sheathed on respectively on the annular groove 212,213 of neutron 21 external diameters 211 of ratchet group 2, then flower drum shell 1 is set on the neutron of ratchet group 2, make the external diameter 211 of the neutron 21 of ratchet group 2 be positioned at the position of the internal diameter 11 of flower drum shell 1, the plum blossom tooth 214 of neutron 21 is matched with the interior plum blossom tooth 12 of flower drum shell 1 together with O type circle 31,32.
Are the interference fit in minimum gap and form at the external diameter 211 of the neutron 21 of the internal diameter 11 of above-mentioned flower drum shell 1 and ratchet group 2 by the upright close-fitting of O type circle 31,32 correcting groups.
Be illustrated in figure 3 as complete cassette flower-drum.Therefore, adopt above-mentioned the utility model structure after, overall weight is lighter, during 2 assemblings of flower drum shell 1 and ratchet group, realizes easily assembling thereby beat reduces, cost is relatively low.
The external diameter 211 of the neutron 21 of the outside face of O type circle 31,32 and flower drum shell 1 internal diameter 11 and above-mentioned ratchet group 2 adopts interference fit.Because be interference fit, can make O type circle 31,32 be subjected to the pressure distortion of flower drum shell 1 and ratchet group 2 simultaneously, during as if flower drum shell 1 and 2 generations of ratchet group gap, O type circle 31,32 hold-off pressures are filled the gap, prevent that flower drum shell 1 from waving.
Fig. 4 is another embodiment of the utility model elastic element, compares with embodiment one, and its difference is:
This O type circle which is provided with breach 311, and it can be suitable for the ratchet group of various sizes and type.
Fig. 5 is the structural representation of the embodiment three of the utility model elastic element and ratchet group, compares with embodiment one, and its difference is:
The neutron 21 of O type circle 31,32 and ratchet group 2 is one-body molded.It can make assembling more convenient, promptly in when assembling, only needs ratchet group 2 and flower drum shell 1 assembled and get final product, does not worry in the fitting process that the thrust that is subjected to flower drum shell 1 because of O type circle 31,32 is rolled on ratchet group 2 surfaces, causes assembling difficult.
What deserves to be explained is that the utility model purposes can be very wide, is not limited to the version of said fixing device.In the similar or similar techniques that those skilled in the art can associate, any anchor fitting, as long as comprise housing and wheels, and described housing can be sheathed on the described wheels to small part, but adopt the fixing spare part of its close-fitting, and between described housing and wheels.Produce the technique effect of beat in the time of can realizing equally reducing housing and wheels assembling.
More than a kind of cassette flower-drum anchor fitting provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and thought thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
