Embodiment
The utility model discloses a kind of seal washer and using its housing waterproof construction, motor, end has been effectively ensured
Waterproof action at lid screw hole, it is to avoid the harm that motor entering water is caused, has evaded the possibility that influence is installed, and makes the anti-of motor
Water is functional, it is simple and compact for structure, firmly install, it is safe and reliable, and easily operation, it is adaptable to produce in enormous quantities.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The seal washer that the utility model embodiment is provided, for the sealing at screw hole, its core improvement is, bag
Washer body and embedding plain washer 132 in the inner are included, structure is referred to shown in Fig. 2-Fig. 4；
Wherein, washer body includes head 131, and its outer end 1311 is used for the head fits with screw 12, washer body head
The inner 1312 in portion 131 surrounds the housing wall of screw (in order to make it easy to understand, below will be with motor in this concrete scheme for same
End cap 11 exemplified by illustrate) coordinate；It is understood that inward-outward direction here is based on for confined state；
Plain washer 132 is set around the central through hole of washer body；
The material of washer body is softer than the material of plain washer 132, and the washer body has the deformation stronger compared with plain washer 132
Ability.It should be noted that above-mentioned screw refers to the screw that tail end is tip, and tail end is that tack needs to coordinate with nut
Bolt.
It can be seen from above-mentioned technical scheme that, the seal washer that the utility model embodiment is provided, because of its washer body
Inside is embedded with plain washer 132, it is not necessary to which extra increase packing ring is tightened, it is possible to reach guarantee screw fastening force purpose；In addition, pad
Enclose main body and select softer material, in assembling because stress produces deformation, its head the inner 1312 is close on end cap 11, rise
To the effect of outside hermetic seal；Meanwhile, screw 12 is also embedded in the head outer end 1311 of washer body to a certain degree, forms contact surface
Seal waterproof.This programme is tightly connected using seal washer and screw 12, screw, with existing use fluid sealant be coated in screw with
Different at gap between screw hole, remaining structure of apparatus casing can maintain versatility without change.
Preferably, plain washer 132 is coaxially disposed with washer body, its structure is referred to shown in Fig. 3, be particularly suitable for use in
The surface of end cap 11 is the situation of plane, further increases fastening ability.
In the specific embodiment that this programme is provided, the distance of plain washer 132 to the inner 1312 arrives outer end 1311 less than it
Distance, its structure is referred to shown in Fig. 3 and Fig. 4.So, plain washer 132 can be near from the bottom surface of end cap 11 after mounting
A bit, it is possible to increase fastening ability, so as to realize better seal effect.When the end face of outer end 1311 or the inner 1312 is not flat
During face, above-mentioned distance refers to plain washer 132 to the axial length of each end face minimum point.
In order to further optimize above-mentioned technical scheme, the end face of the inner 1312 has the sealing rim of annular protrusion, should
Axial direction of the rim along the central through hole of head 131 is raised away from the inner 1312, for being close in assembling because stress is deformed upon
On end cap 11, outside hermetic seal effect is improved.Specifically, arc transition between the rim of the inner 1312 and its bottom surface.It is tied
Structure is referred to shown in Fig. 3 Fig. 4, and inner 1312 this rim have certain angle with its bottom surface, in the state outwards lain prone, when by
During power, the rim can be faced out and be close to along end cap due to angle, play a part of sealing.
Preferably, the end face of outer end 1311 is ramp structure low between surrounding senior middle school.Its structure is referred to Fig. 3 Fig. 4
Shown, when by 12 active force of screw, due to gradient, the end face of outer end 1311 can be deformed to contract, make its with
The laminating of the bottom surface of head of screw 12 is closer, so as to improve sealing effectiveness.
In the specific embodiment that this programme is provided, washer body also includes the afterbody 133 for being connected to head the inner 1312,
To improve waterproof effect, as shown in figure 3, the afterbody 133 is loop configuration, its inwall and the inwall on head 131 are located at same circle
On cylinder, outer wall is the periphery coordinated for the inwall of same screw hole.Preferably, the head 131 of washer body and afterbody
133 are integrally formed, and contribute to sealing.
In order to further optimize above-mentioned technical scheme, arc transition between the outer wall of afterbody 133 and head the inner 1312.
Such structure can be deformed upon when coordinating with the screwed hole of end cap 11, and laminating between the two is closer, and sealing effectiveness is prevented
Water is more preferable.
In the specific embodiment that this programme is provided, washer body is quality of rubber materials, with high resiliency, insulating properties, impermeable
The characteristic of water and air, disclosure satisfy that requirement of the design for deformation nature and sealing effectiveness.Plain washer 132 can be using hard
Metal material.
Preferably, plain washer 132 is embedded in inside washer body, it can be installed by opening up notch inside washer body
Realize, or washer body is obtained in the external process shaping of plain washer 132.
The utility model embodiment additionally provides a kind of housing waterproof construction, including screw 12, packing ring and nut, its core
Improvement is that packing ring is seal washer 13 described above, and the screw portion of the screw 12 sequentially passes through seal washer 13 and shell
The screw hole of body (end cap 11 of such as motor), and tightened with nut cooperation.Set between motor screw and the screw hole of front motor cover
Motor screw waterproof washer (i.e. above-mentioned seal washer) is put, screw, screw hole and waterproof washer are tightly connected, and pass through screw
Cooperation between nut is fastened, and reaches waterproof purpose.The design can be widely applied to it is all kinds of to degree of protection have will
The device asked, especially charging equipment such as electrical equipment.
The utility model embodiment additionally provides a kind of motor, and waterproof knot is provided with the screw hole of its housing end plug 11
Structure, its core improvement is that waterproof construction is above-mentioned housing waterproof construction.As shown in Figure 2 and Figure 4, the screw rod of screw 12
Part is passed through from sealing gasket collar aperture, drive end bearing bracket screw, stator core hole, rear end cap screw successively.Head of screw is close to drive end bearing bracket
11 face is close on seal washer, and screw afterbody is passed from rear end cap bore, and is tightened with nut cooperation.Seal washer head
131 two faces are contacted with screw 12, drive end bearing bracket 11 respectively；Afterbody is penetrated from preceding head bolts hole.The technical program is effectively protected
The waterproof action at head bolts hole is demonstrate,proved, it is to avoid the harm that motor entering water is caused, has evaded the possibility that influence is installed, made electricity
The water resistance of machine is good, it is simple and compact for structure, firmly install, safe and reliable, and easily operation, it is adaptable to produce in enormous quantities.
Assembling process is as follows：
1st, seal washer afterbody is passed from preceding head bolts hole, seal washer head is contacted with front end exterior surface；
2nd, the drive end bearing bracket with seal washer, rear end cap and casing coordinate and placed；
3rd, the screw portion of screw is passed through from collision mat collar aperture, through stator core hole, is passed from rear end cap screw hole, and
Fastened with nut.
