Abstract
The utility model discloses a step screw with a spring. The screw comprises a screw body and the spring, an under-screw head step is provided with an extrusion-formed fastening groove, and one end of the spring is sleeved on the screw and fastened in the fastening groove. During production, the spring and the screw are assembled together through the fastening groove before the step screw is directly delivered to customers, consequently, the step screw can be used without being assembled any more by customers, and thereby the assembling efficiency is greatly increased.
Description
Technical field
The utility model relates to screw, more particularly, relates to a kind of step screw with spring.
Background technique
Traditional step screw is as shown in Figure 1, and this screw comprises screw body 10 and spring 11, and 12 positions do not have catching groove because this screw terminal is got out of a predicament or an embarrassing situation; Therefore can only screw body 10 and spring be opened the packing shipment in 11 minutes and give the client; Produce line when assembling the client, once take a screw body 10 and a spring 11, be assembled on the complete machine after being enclosed within spring 11 on the screw body 10; Because this screw consumption is very big, therefore use aforesaid way assembling overall efficiency very low.
The model utility content
To the above-mentioned shortcoming that exists in the existing technology, the purpose of the utility model provides a kind of step screw with spring, can when producing, be about to screw and be assembled together and shipment with spring, and the confession client directly installs.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The step screw of this band spring comprises screw body and spring, and the described screw terminal position of getting out of a predicament or an embarrassing situation is provided with together through the catching groove of extrusion modling, and spring one end is sheathed on the screw and is arranged in the catching groove.
In technique scheme, the step screw of the band spring of the utility model comprises screw body and spring, and the screw terminal position of getting out of a predicament or an embarrassing situation is provided with together through the catching groove of extrusion modling, and spring one end is sheathed on the screw and is arranged in the catching groove.When producing, spring and screw are assembled together through catching groove, directly the client is given in delivery, and so the client need not to assemble again and can use, and has improved packaging efficiency greatly.

Fig. 2 is the step screw of the utility model and the exploded view of spring;
Fig. 3 is the step screw of the utility model and the erection drawing of spring.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 2～shown in Figure 3, the step screw and the existing technology of the band spring of the utility model are basic identical, equally also comprise screw body 20 and spring 21, and are provided with step in the screw terminal bottom.22 different with it are; Be provided with catching groove 23 one at screw terminal 22 positions of getting out of a predicament or an embarrassing situation; This catching groove 23 can be in the screw manufacture process; Mode through extrusion modling is made, and spring 21 1 ends are sheathed on the screw body 20 and through being arranged in the catching groove 23, realize the mount with screw body 20.
Adopt the screw of the utility model; Can be in process of production; Be about to spring 21 and be assembled together through catching groove 23 with screw body 20 and, directly deliver, need not the packing delivery to the client as finished product; And also need not after the client receives to assemble again and promptly can be used for complete machine assembling, improved packaging efficiency greatly.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
