Abstract
The utility model discloses a kind of screw with resilient pad, aim to provide a kind of screw with resilient pad that improves installation efficiency, its technological scheme main points are to be connected with connecting rod between screw cap and lead screw, connecting rod external diameter is less than lead screw external diameter, pad is provided with installation through hole, pad is arranged in connecting rod by through hole is installed, the structure setting that is in the shape of the letter V of pad cross section, pad opening is towards lead screw one side, through hole ovalize structure is installed to be arranged, short diameter and connecting rod external diameter that through hole is installed are suitable, the short diameter that through hole is installed is less than lead screw external diameter, pad be shaped as rectangle.Mode by adopting punching press pad is by the pad manufacturing structure that is in the shape of the letter V, simultaneously by original circular mounting through hole along with pad is stamped and forms ellipsoidal structure, make to install through hole minimum diameter and be less than lead screw external diameter, make pad difficult drop-off, reduced or remitted the step of manually wearing pad, reduce staff's workload, also made installation efficiency higher.
Description
Technical field
The utility model relates to a kind of screw, and more particularly, it relates to a kind of screw with resilient pad.
Background technique
Screw is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, the by easy stages instrument of fastening implements parts.When using fastened by screw implements parts, often need screw tie spacer lock and relative position fixing, to improve the steadiness being fastenedly connected, make screw be difficult for producing and become flexible.Yet in prior art, the method that pad is manually worn in general employing, had both increased staff's workload, also made installation efficiency lower.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of screw with resilient pad that improves installation efficiency.
For achieving the above object, the utility model provides following technological scheme: a kind of screw with resilient pad, comprise screw cap, lead screw and pad, between described screw cap and lead screw, be connected with connecting rod, described connecting rod external diameter is less than lead screw external diameter, described pad is provided with installation through hole, this pad is arranged in connecting rod by through hole is installed, the structure setting that is in the shape of the letter V of described pad cross section, this pad opening is towards lead screw one side, described installation through hole ovalize structure arranges, this short diameter and connecting rod external diameter that through hole is installed is suitable, the short diameter of described installation through hole is less than lead screw external diameter, described pad be shaped as rectangle.
Described pad is provided with the groove for accommodating screw cap with respect to the crest place of screw cap one side.
Described pad is provided with stiffening rib.
A kind of screw with resilient pad, comprise screw cap, lead screw and pad, between described screw cap and lead screw, be connected with connecting rod, described connecting rod external diameter is less than lead screw external diameter, described pad is provided with installation through hole, this pad is arranged in connecting rod by through hole is installed, the structure setting that is in the shape of the letter V of described pad cross section, this pad opening is towards lead screw one side, described installation through hole ovalize structure arranges, this short diameter and connecting rod external diameter that through hole is installed is suitable, the short diameter of described installation through hole is less than lead screw external diameter, described pad be shaped as rectangle.By adopting technique scheme, pad is arranged in after connecting rod by through hole is installed, mode by adopting punching press pad is by the pad manufacturing structure that is in the shape of the letter V, simultaneously by original circular mounting through hole along with pad is stamped and forms ellipsoidal structure, make the internal diameter that through hole is installed dwindle with connecting rod suitable, through hole minimum diameter is installed simultaneously and is less than lead screw external diameter, make pad difficult drop-off, reduced or remitted the step of manually wearing pad, reduce staff's workload, also made installation efficiency higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the screw of the utility model band resilient pad;
Fig. 2 is the structural representation of pad.
Reference character: 1, screw cap; 2, lead screw; 3, pad; 4, connecting rod; 31, through hole is installed; 32, groove; 33, stiffening rib.
Embodiment
With reference to Fig. 1, Fig. 2, the screw embodiment of the utility model band resilient pad is described further.
A kind of screw with resilient pad, comprise screw cap 1, lead screw 2 and pad 3, between described screw cap 1 and lead screw 2, be connected with connecting rod 4, described connecting rod 4 external diameters are less than lead screw 2 external diameters, described pad 3 is provided with installs through hole 31, this pad 3 is arranged in connecting rod 4 by through hole 31 is installed, the structure setting that is in the shape of the letter V of described pad 3 cross sections, these pad 3 openings are towards lead screw 2 one sides, described installation through hole 31 ovalize structures arrange, these installation through hole 31 internal diameters and connecting rod 4 external diameters are suitable, described installation through hole 31 minimum diameters are less than lead screw 2 external diameters, described pad 3 be shaped as rectangle.Pad 3 is arranged in after connecting rod 4 by through hole 31 is installed, mode by adopting punching press pad 3 is by the pad 3 manufacturing structure that is in the shape of the letter V, simultaneously by original circular mounting through hole 31 along with pad 3 is stamped and forms ellipsoidal structure, make the internal diameter that through hole 31 is installed dwindle with connecting rod 4 suitable, through hole 31 minimum diameters are installed simultaneously and are less than lead screw 2 external diameters, make pad 3 difficult drop-offs, reduced or remitted the step of manually wearing pad 3, reduce staff's workload, also made installation efficiency higher.The pad 3 of the structure that is in the shape of the letter V setting has elastic force upwards after installation, can avoid screw to produce loosening and affect stable connection.Simultaneously the shape of pad 3 can be ellipse, circle, rectangle etc., as best preferred version of the present utility model, pad 3 be shaped as rectangle, two seamed edges of rectangular washer 3 are conducive to improve the installation steadiness of pad 3.
Described pad 3 is provided with the groove 32 for accommodating screw cap 1 with respect to the crest place of screw cap 1 one sides.Groove 32 makes screw convenient for screw cap 1 provides good, firm clamping origin of force when fastening, avoids screw cap 1 in crest place, to swing when fastening, affects final stable connection.
Described pad 3 is provided with stiffening rib 33.Stiffening rib 33 has strengthened the rigidity of pad 3, makes it be difficult for deformed damaged, has extended the working life of pad 3.
