Screw
The utility model relates to a kind of screw.
Screw is a kind of element that can be connected and fixed object rapidly, for should various utensils different demands when the assembling, and made various form.With crosshead screw commonly used is example, as shown in Figure 1, this screw 1 has a body of rod 11 and is connected with at the head 12 of the body of rod 11 1 ends etc. partly, be equipped with screw thread 111 on this body of rod 11, in addition, be formed with a groove 121 on this head 12, and be provided with short slot 122 relative in twos and that be interconnected, be formed with an inclined-plane 123 respectively in the jointing place of per two adjacent short slots 122 simultaneously at the periphery of this groove 121.When this screw 1 desires to lock two working substances, can use a kind of cross bottle opener 13, or use four angle head type bottle openers (figure does not show).No matter and the bottle opener head dummy is how, all need cooperate groove 121 shapes of screw head, can stretch in order to the bottle opener head and insert in the groove 121, so as to utilizing the rotation of this cross bottle opener 13 or four angle head type bottle openers, and make this screw 1 can sealed two articles.
But though the groove 121 that the head 12 of general screw 1 forms can supply cross bottle opener 13, or instrument such as four angle head type bottle openers stretches and puts, to reach the sealed purpose of this screw 1.But the hand tools that this screw 1 is suitable for has only two kinds, hand toolss such as just cross bottle opener 13 or four angle head type bottle openers.But, hand tools commonly used at present not only has four angle head types or cross bottle opener 13, also has a kind of yi word pattern bottle opener.So, the groove 121 of screw 1 head 12 moulding of or dismounting sealed when desire, its hand tools applicatory be as too complicated, can make when the user desires to carry out sealed or dismounting at this screw 1, must use the cooperation of multiple hand tools, just can reach the sealed or dismounting of this screw 1.So, can influence user's activity duration because of the replacing of hand tools, cause delaying of time and reduce working efficiency, also may or leave behind simultaneously because of the searching of hand tools, cause in the operation very inconvenient.
The purpose of this utility model is to provide a kind of screw, and it can be used various hand toolss and finish sealedly, has increased the convenience that uses.
The technical solution of the utility model provides a kind of screw, comprise a body of rod and be connected with head at this body of rod one end, be equipped with screw thread on this body of rod, and be formed with a groove on this head, this groove has short slot relative in twos and that be interconnected, the jointing place of two adjacent short slots is formed with an inclined-plane respectively, it is characterized in that:
Two relative short slots extend to this external edge of head respectively, and are respectively equipped with a groove that is communicated with short slot, and this groove depth and short slot depth ratio are between 1: 4 to 2: 3, and this two groove and two corresponding short slots form in-line.
In sum, the effect of screw of the present utility model is, the user only need use the wherein a kind of of four angle head types, crosshead and yi word pattern bottle opener, just can reach operations such as screw closure or dismounting, more must not lose time and change or seeking on the hand tools that is suitable for, thereby the time that can shortening work delays is with effective enhancement working efficiency.
, be elaborated to screw of the present utility model below by preferred embodiment and accompanying drawing, in the accompanying drawing:
Fig. 1 is the schematic perspective view of general screw.
Fig. 2 is the schematic perspective view of the utility model preferred embodiment.
Fig. 3 is the generalized section of the utility model preferred embodiment.
Look schematic representation in the preferred embodiment of Fig. 4 the utility model.
Fig. 5 looks schematic representation on another of the utility model preferred embodiment.
Fig. 6 looks schematic representation on the utility model preferred embodiment another.
Shown in Fig. 2,3, screw 2 of the present utility model comprises a body of rod 21 and is connected with head 22 at this body of rod 21 1 ends.
Be equipped with screw thread 211 on this body of rod 21, in addition, be formed with a groove 221 on these head 22 tops, and has short slot 222 relative in twos and that be interconnected at this groove 221, the jointing place of in office two adjacent short slots 222 is formed with an inclined-plane 223 respectively simultaneously, and along short slot 222 facing each other and extend to respectively on the position of head 22 outer rims, be respectively equipped with a groove 224, and this groove 224 is connected with short slot 222, simultaneously, the depth ratio of the degree of depth of this groove 224 and short slot 222 is between 1: 4 to 2: 3, when just the degree of depth of this groove 224 is 0.008~0.161mm, and the degree of depth 0.032~0.260mm of this short slot 222 then, in addition, this two groove 224 and two corresponding short slots 222 form in-line, put so that this groove 224 can be stretched for yi word pattern bottle opener 23, and can give sealed.
Cooperate shown in Figure 4, when the two work material desires that separate when engaging, can adopt the screw shown in the present embodiment, at first this screw 2 is placed sealed point location, this moment can be more for sealed bottle opener head dummy because of these screw 2 heads 22 grooves 221, the available screwdriver head dummy of user is unrestriction also, more can increase the convenience of use, the user mode of Fig. 4 be sealed with yi word pattern bottle opener 23 be example, when this yi word pattern bottle opener 23 is stretched when inserting in this groove 224, groove 224 2 lateral margins of this screw 2 can touch mutually with this yi word pattern bottle opener 23, and when this yi word pattern bottle opener 23 advances sealed action, this yi word pattern bottle opener 23 be utilize its termination bi-side respectively to the two lateral margin application of forces of this groove 224, and can make this screw 2 turns, so that this screw 2 is locked in the object, and give sealed location.
Cooperate shown in Figure 5, when this screw 2 desires to carry out sealed action with cross bottle opener 24, can directly this cross bottle opener 24 be stretched and insert in screw 2 grooves 221, just should stretch into simultaneously in short slot 222 and the groove 224 by cross bottle opener 24, be rotated sealed action in order to this cross bottle opener 24, and this screw 2 is locked in the object.
As shown in Figure 6, this four angle heads bottle opener 25 is stretched in the groove 221 of inserting screw 2, and cooperate with four flank side surface of four angle head type bottle openers 25 by 222 formed inclined-planes 223 of this short slot, when this four angle heads bottle opener 25 is rotated when sealed, can make this screw 2 be subjected to its drive and the two articles that locks.
