Description
Technical Field
The utility model relates to the technical field of hardware processing, in particular to a spring screw capable of buffering.
Background
The spring screw is also called as a loose-free screw, and generally comprises a handle, a screw rod, a sleeve head and a spring, wherein two ends of the spring are respectively fixed or semi-fixed with the handle and the sleeve head, so that the spring screw can only be stored and transported in a whole set. The spring cannot be replaced once it breaks, metal fatigue and rust etc. occur during storage or transport. In addition, threads are arranged on the periphery of the screw rod in the prior art (see Chinese patent No. 202122662050.4, which is a novel spring screw), so that the movable friction force of the sleeve head on the screw rod is large, and the screw rod needs large force to screw, so that the screw rod is not easy to screw into the mounting hole.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a spring screw capable of buffering.
The technical scheme of the utility model is as follows:
the utility model relates to a spring screw capable of buffering, which comprises a handle, a shaft, a spring and a sleeve head, wherein the front end surface of the handle is fixedly connected with the shaft, the shaft comprises a polished rod and a screw rod, the spring and the sleeve head are sleeved on the shaft, the spring is positioned between the handle and the sleeve head, and other parts except the handle and the shaft are fixedly connected, so that the spring can be detached and replaced when abnormal conditions such as cracks, rust and the like occur before use, and the quality of the spring is ensured to be in accordance with the standard when the spring screw is used.
Further, anti-slip teeth are arranged on the periphery of the handle, so that the hand can conveniently exert force when screwing in the screw rod, and an anti-slip effect is achieved.
Further, the pullover includes step, fender ring and riveting ring, and the step is towards the handle, and the step front end is fixed to be provided with the fender ring, and the fender ring front end is fixed to be provided with the riveting ring, the external diameter of step is less than the external diameter of fender ring, and the step periphery can be convenient for the spring winding, prevents the unexpected clearance department of inserting between axle and the pullover of spring tip.
Further, the handle, the shaft and the sleeve head are made of carbon steel, strength is guaranteed, the spring is made of 304 stainless steel, and rust resistance is improved.
Further, the handle, the shaft and the sleeve head are externally plated with a white nickel coating, the handle is provided with the white nickel coating which can prevent rust, the white nickel coating on the shaft and the sleeve head is convenient for visual inspection of rust points, the white nickel coating is a silver-colored metal layer, once rust points are obvious, the screw rod of the shaft and the riveting ring of the sleeve head are provided with threads or concave patterns, if zinc plating or blackening treatment is adopted, rust points in the screw rod and the riveting ring are difficult to find, and the existence of the rust points is unfavorable for screw connection or riveting.
The beneficial effects of the utility model are as follows: the handle and the shaft are integrally formed, so that the connection strength of the handle and the shaft is improved; the spring and the sleeve head are detachable pieces, and the spring is damaged and can be replaced; the shaft is provided with a polish rod and a screw rod, the polish rod is beneficial to moving the sleeve head, and the screw rod is used for being screwed into the target mounting hole.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure, 1, a handle; 2. a shaft; 3. a spring; 4. a sleeve head; 11. anti-slip teeth; 21. a polish rod; 22. a screw; 41. a step; 42. a baffle ring; 43. and riveting the ring.
Detailed Description
The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:
as shown in fig. 1, the buffering spring screw comprises a handle 1, a shaft 2, a spring 3 and a sleeve head 4, wherein the front end surface of the handle 1 is fixedly connected with the shaft 2, the shaft 2 comprises a polished rod 21 and a screw rod 22, the spring 3 and the sleeve head 4 are sleeved on the shaft 2, and the spring 3 is positioned between the handle 1 and the sleeve head 4.
The periphery of the handle 1 is provided with anti-slip teeth 11.
The sleeve head 4 comprises a step 41, a baffle ring 42 and a riveting ring 43, the step 41 faces the handle 1, the baffle ring 42 is fixedly arranged at the front end of the step 41, the riveting ring 43 is fixedly arranged at the front end of the baffle ring 42, and the outer diameter of the step 41 is smaller than the outer diameter of the baffle ring 42.
The handle 1, the shaft 2 and the sleeve head 4 are all made of carbon steel, and the spring 3 is made of 304 stainless steel.
The outer surfaces of the handle 1, the shaft 2 and the sleeve head 4 are plated with white nickel plating layers.
The application method of the utility model comprises the following steps:
1) The riveting ring of the sleeve head is directed to the target mounting hole and is riveted with the mounting hole by using a tool (compared with a spring screw which cannot be detached, the riveting process of the utility model is easier to operate);
2) Sleeving the spring outside the step of the sleeve head, and enabling the shaft to penetrate through the spring and enter the through hole of the sleeve head;
2) The screw rod is screwed in towards the target mounting hole by rotating the handle.
The foregoing embodiments and description have been provided merely to illustrate the principles and best modes of carrying out the utility model, and various changes and modifications can be made therein without departing from the spirit and scope of the utility model as defined in the appended claims.
