Abstract
The utility model discloses an anticollision flange type shaft core, which comprises a fixed part fixed in a shell, a heat part positioned on one end of the fixed part and a rotary tail part positioned on the other end of the fixed part, wherein at least part of the head part is covered by a split type shaft cap; and the shaft cap has a flange. The utility model has the advantages that: the strength, quality and service life of the product are improved considerably; product after-sales service, management and sale costs are reduced; resources waste is reduced; a green and environmental protection requirement is met; the installation efficiency is high; the reject rate is reduced; and a large impact force can be withstood.
Description
Technical field
The utility model relates to a kind of crashproof flanged type axle center, especially a kind of crashproof flanged type axle center that is used on the rotary switch.
Background technology
Rotary switch is used on the equipment of being fixed in or the instrument more on the market, and industrial is handled easily, it can be installed on the wired remote control box.If because of carelessness it is fallen on the ground, through regular meeting distortion is hit in its switch axle center, just block easily in the axle center, causes and can't rotate, and need whole rotary switch is changed, and causes the waste of resource and influence greatly and produce.For solving this difficult problem, propose in the industry the two ends in axle center are fixed, adopt C type clasp to fix and be exposed on the external, but still be subject to external force collision and damage.
Summary of the invention
The utility model purpose is: a kind of crashproof flanged type axle center is provided, has solved defectives such as being subject to external force collision.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of crashproof flanged type axle center, it comprises a fixed part, is positioned at the head of fixed part one end and is positioned at the fixed part other end and rotatable afterbody that wherein said head is coated by separate type axle cap a to small part.
On the basis of technique scheme, further comprise:
The bottom of described axle cap is formed with a flange, and its diameter is greater than the diameter of head.
The centre of described axle cap is provided with one and cooperates fixing cavity with the head in axle center.
Be provided with internal thread in the described cavity, and the head in axle center is provided with external screw thread.
Adopt the utility model, intensity, quality, the useful life that can significantly improve product, and reduce after services of product and barrel bolt cost, and reduce the wasting of resources, and meeting environmental protection, the installation effectiveness height reduces fraction defective and can bear bigger impact.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a decomposing schematic representation of the present utility model.
Fig. 2 is an assembling schematic diagram of the present utility model.
Fig. 3 is the part-structure schematic diagram that the utility model is applied to rotary switch.
Embodiment
Please refer to Fig. 1-3, a kind of rotary switch 1 of the present utility model, it comprises a shell 30 and an axle center, this axle center comprises the fixed part 12 that is fixed in the shell 30, be positioned at the head 14 of fixed part 12 1 ends and be positioned at fixed part 12 other ends and rotatable afterbody 16, wherein said head 14 is coated by a separate type axle cap 20 to small part, the bottom of described axle cap 20 is formed with a flange 22, its diameter is greater than the diameter of head 14, and the upper surface of the lower surface of flange 22 and shell 30 against, and the centre of axle cap 20 is provided with one and cooperates fixing cavity 24 with the head 14 in axle center.Wherein the mode that cooperates with cavity 24 of head 14 can be provided with internal thread in cavity 24, and the head 14 in axle center then is provided with external screw thread, also can adopt both mutually bonding mode realize fixing.
In sum, the utility model adopts the axle center design with integral type to have the axle cap of flange to be set on the axle center instead, when the axle center was subjected to clashing into, axle cap can be scattered in impact F the tube wall of shell 30, so just can avoid the one-sided distortion in axle center and influenced its use.
Adopt the utility model, intensity, quality, the useful life that can significantly improve product, and reduce after services of product and barrel bolt cost, and reduce the wasting of resources, and meeting environmental protection, the installation effectiveness height reduces fraction defective and can bear bigger impact.
When embodiment of the present utility model is illustrated and describes, conceivable is that those skilled in the art can design different correction examples of the present invention under the situation of spirit that does not break away from claims and scope.
