Abstract
The utility model relates to a round port screw, which comprises a threaded rod and threads, wherein the threaded rod comprises a threaded rod main body, a screw head arranged at one end of the threaded rod main body and a screw tail arranged at the other end of the threaded rod main body, wherein the screw tail is provided with a groove for the screwing, and the screw head is semi-circular. The diameter of the screw head is equal to the diameter of the threaded rod main body, the screw head is in interference fit with a screw opening, and the groove is in a - shape or in a cross shape. When the round port screw is used for fixing a product, the screw is screwed into the screw opening for fixing the product through the groove of the screw tail of the screw. Because the screw head of the screw is designed into a half round shape and the screw head is in interference fit with the screw opening, when the screw is screwed tightly, no gap is reserved between the screw opening and the screw, and the round port screw cannot be loosened easily and is good in fastening performance and tightness. When the product is subjected to the effect of external force, the screw limits the product while fixing the product, and has the reacting force and fixing and locating effects.
Description
Technical field
The utility model relates to a kind of circular port screw.
Background technique
Though screw has good locking function, also exist to be prone to loosening situation, because the spiral shell head of normal screws is put down; When tightening, also have the space in the screw, air and moisture are run into easily; Cause product easily loosening and break away from when being given a shock, cause unnecessary trouble.In order to avoid this situation, need a kind of difficult loosening and better screw of tightness of design.
Summary of the invention
The technical problem that the utility model will solve provide a kind of be difficult for loosening, tightness is good, have reaction force and the circular port screw of stationary positioned effect is arranged.The utility model is realized through following technological scheme:
A kind of circular port screw of the utility model; Comprise screw rod and screw thread, said screw rod comprises the screw rod main body, and is arranged on the spiral shell head and the spiral shell tail that is arranged on the screw rod main body the other end of screw rod main body one end; Said spiral shell tail is provided with and is used to unscrew tight groove, and said spiral shell head is semicircle.
As preferably, said spiral shell head diameter is identical with the screw rod main diameter.
As preferably, said spiral shell head and screw socket are interference fit.
As preferably, said groove is in-line or cross.
The circular port screw of the utility model, when being used for fixing product, the groove through screw spiral shell tail is screwed into the screw socket of fixed product with screw, because the spiral shell head of said screw is designed to semicircle, and spiral shell head and screw socket
Be interference fit, behind the tightening the screw, do not have the space between screw socket and the screw, be difficult for becoming flexible, firmly performance is done the time spent with closely performance is good when product receives external force, and screw retrains product, the effect that has reaction force and have stationary positioned in fixed product.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 does not change preceding schematic representation for the utility model circular port screw;
Fig. 2 is the schematic representation of the utility model circular port screw.
Embodiment
As shown in Figure 2; A kind of circular port screw of the utility model; Comprise screw rod 1 and screw thread 2, said screw rod 1 comprises screw rod main body 11, and is arranged on the spiral shell head 12 and the spiral shell tail 13 that is arranged on screw rod main body 11 the other ends of screw rod main body 11 1 ends; Said spiral shell tail 13 is provided with and is used to unscrew tight groove 14, and said spiral shell head 12 is semicircle.It has the characteristics loosening, that tightness is good that are difficult for.
Wherein, said spiral shell head 12 diameters are identical with screw rod main body 11 diameters.Said spiral shell head 12 is an interference fit with screw socket.Said groove 14 is in-line or cross.
The circular port screw of the utility model when being used for fixing product, is screwed into screw through the groove of screw spiral shell tail the screw socket of fixed product; Because the spiral shell head of said screw is designed to semicircle, and spiral shell head and screw socket be interference fit, behind the tightening the screw; Do not have the space between screw socket and the screw, be difficult for becoming flexible, firmly performance is with closely performance is good; Do the time spent when product receives external force, screw retrains product, the effect that has reaction force and have stationary positioned in fixed product.
The foregoing description; It is an instance of the utility model; Be not enforcement and the interest field that is used for limiting the utility model, all and the said same content of the utility model claim or the technological scheme that is equal to all should be included in the utility model protection domain.
Claims (4)
1. circular port screw; Comprise screw rod and screw thread, said screw rod comprises the screw rod main body, and is arranged on the spiral shell head and the spiral shell tail that is arranged on the screw rod main body the other end of screw rod main body one end; Said spiral shell tail is provided with and is used to unscrew tight groove, it is characterized in that: said spiral shell head is for semicircle.
2. circular port screw according to claim 1 is characterized in that: said spiral shell head diameter is identical with the screw rod main diameter.
