Abstract
The utility model provides a kind of motor for preventing and loosens the screw a little, mounted motor is used for nut screw connection, described jam nut is by spiral shell head and screw rod is one-body molded forms, the locking teeth that bottom described spiral shell head, impact briquetting has stepped wave tooth to be formed, described locking teeth and described nut screw connection bite mating face getting loose on direction.When there being release force to be formed at threaded portion, locking teeth can bite mating face toward the direction that gets loose, be not released under certain moment, compared with prior art, do not need to increase pad, decrease accessory, improve manufacturing efficiency, decrease artificial use simultaneously, incorporate Component, effectively reduce cost.
Description
Technical field
The utility model relates to hardware, particularly relates to a kind of motor for preventing and loosens the screw a little.
Background technique
In manufacturing, in the face of manufacture cost is more and more higher, how to reduce the important research project of integration Shi Ge factory always of artificial use, multiple Component.But the existing screw used on motor does not possess anti-loosening function, need to increase locking bullet pad to realize anti-loosening function, need manually locking bullet pad to be penetrated on screw, play and increase frictional force effect, but use locking bullet pad, add extra accessory; And need manual operation, and add workload, very inconvenient.
Model utility content
The purpose of this utility model is the defect overcoming prior art, and providing one does not need the simple motor for preventing of accessory, structure to loosen the screw a little.
The utility model is achieved in that a kind of motor for preventing is loosened the screw a little, mounted motor is used for nut screw connection, described jam nut is by spiral shell head and screw rod is one-body molded forms, the locking teeth that bottom described spiral shell head, impact briquetting has stepped wave tooth to be formed, described locking teeth and described nut screw connection bite mating face getting loose on direction.
Further, described locking teeth to be equally spaced distributed in bottom described spiral shell head on bottom surface, place.
Further, described jam nut adopts rigid shaping, and described spiral shell head is circular, and described screw rod is cylindric, and described screw rod one end is provided with outside thread.
The utility model provides a kind of motor for preventing to loosen the screw a little, mounted motor is used for nut screw connection, described jam nut is by spiral shell head and screw rod is one-body molded forms, the locking teeth that bottom described spiral shell head, impact briquetting has stepped wave tooth to be formed, described locking teeth and described nut screw connection bite mating face getting loose on direction.When there being release force to be formed at threaded portion, locking teeth can bite mating face toward the direction that gets loose, be not released under certain moment, compared with prior art, do not need to increase pad, decrease accessory, improve manufacturing efficiency, decrease artificial use simultaneously, incorporate Component, effectively reduce cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 to loosen the screw a little stereogram for motor for preventing that the utility model embodiment provides;
Fig. 2 to loosen the screw a little plan view for motor for preventing that the utility model embodiment provides;
Fig. 3 to loosen the screw a little plan view for motor for preventing that the utility model embodiment provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 3, the utility model embodiment provides a kind of motor for preventing to loosen the screw a little 1, coordinate with nut (not shown) and be used for mounted motor (not shown), described jam nut 1 is by spiral shell head 11 and screw rod 12 is one-body molded forms, the locking teeth 112 that bottom described spiral shell head, 111 impact briquettings have stepped wave tooth to be formed, described locking teeth 112 and described nut screw connection bite mating face getting loose on direction.Due to generally can vibration be produced during motor load, in long-time situation, can loosen between nut and jam nut 1, when there being release force to be formed at screw 1 position, locking teeth 112 biting mating face toward the direction that gets loose, can not be released, compared with prior art under certain moment, do not need to increase pad, decrease accessory, improve manufacturing efficiency, decrease artificial use simultaneously, incorporate Component, effectively reduce cost.
In embody rule, as Fig. 1, Fig. 3, described locking teeth 112 to be equally spaced distributed in bottom described spiral shell head 11 on bottom surface, place.One, is convenient to impact briquetting; The second, convenient be engaged when occurring loosening between nut tighter; Its three, appearance looks elegant.
Further, as shown in Figure 1, Figure 2, described jam nut 1 adopts rigid shaping, has the strong advantage of hardness; Described spiral shell head 11 is in circular, and described screw rod 12 is in cylindric, and described screw rod 12 one end is provided with outside thread 121, is convenient to assemble mutually with nut.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
