Description
本發明一種扳手迫緊裝置,詳指應用於扳手領域之技術,主要用以防止螺絲及端蓋於D頭長期的驅動旋轉後而鬆脫,即為一種實用性極佳之發明。The wrench tightening device of the present invention refers in detail to the technology applied in the wrench field. It is mainly used to prevent screws and end caps from loosening after the D head is driven and rotated for a long time. It is an invention with excellent practicability.
扳手主要用途是可以直接對零件進行驅動,而使零件得以緊鎖或是卸除於鎖固的位置,提供使用者輕鬆且方便的進行施工作業,然而扳手的類型常用的可大致區分為開口(梅花)扳手以及須配合套筒組接之D頭扳手,又開口(梅花)扳手的結構較為單純,主要係以開口處呈現為多邊形型態,方便套組於螺絲的頭端、螺帽的外周進行驅動,利用螺絲、螺帽也為多邊形配合開口(梅花)扳手的開口形狀,使其能夠拆卸、旋緊;而今要討論的是前述所說的D頭扳手,常見的D頭扳手在結構的設置上,主要在D頭扳手的一端會設置有用以封蓋的一旋蓋、提供套筒套接之D頭、提供套筒卡接定位於D頭或是脫離D頭的控壓組,其中控壓組具有一螺絲、一端蓋及一心軸,又該心軸會穿設D頭並以以彈簧推動一定位鋼珠局部凸露於D頭外,利用定位鋼珠卡接套筒,當要拆卸套筒時則按壓端蓋控制心軸移動進行解除定位鋼珠卡接套筒,而螺絲則是將端蓋鎖接於心軸一端使心軸能夠裝設在扳手本體,另外還具有一多邊形螺帽介於旋蓋內並鎖設於D頭,使得D頭可以與旋蓋組接並裝設於D頭扳手。The main purpose of the wrench is to directly drive the parts so that the parts can be locked or removed in the locked position, providing users with easy and convenient construction operations. However, the commonly used types of wrenches can be roughly divided into openings ( Torx wrenches and D-head wrenches that must be assembled with a socket. The structure of the open (torx) wrenches is relatively simple. The openings are mainly polygonal, which is convenient to set on the head end of the screw and the outer periphery of the nut. For driving, the screw and nut are also polygonal with the opening shape of the open (torx) wrench, so that it can be disassembled and tightened; what we are going to discuss now is the aforementioned D-head wrench, the common D-head wrench is in the structure In terms of installation, one end of the D-head wrench is mainly provided with a screw cap for capping, a D-head for socket socket, and a pressure control group for socket-clamping and positioning on the D-head or detached from the D-head. The pressure control group has a screw, one end cover and a mandrel, and the mandrel will pass through the D head and use a spring to push a positioning steel ball to partially protrude outside the D head. The positioning steel ball is used to clamp the sleeve. When the sleeve is to be removed When barreling, press the end cover to control the movement of the mandrel to release the positioning of the steel ball clamping sleeve, while the screw locks the end cover to one end of the mandrel so that the mandrel can be installed on the wrench body, and also has a polygonal nut In the screw cap and locked on the D head, so that the D head can be assembled with the screw cap and installed on the D head wrench.
上述的D頭扳手即是現今市面上常見的結構型態,而D頭扳手所具有的優點在於,使用者不用如開口(梅花)扳手般為了應付不同尺寸的螺絲、螺帽,以至於要隨身攜帶多支不同開口尺寸的開口(梅花)扳手,既麻煩又增加負重,而D頭扳手僅需要以一支通用的扳手配合不同尺寸的套筒組裝即可應對各種尺寸的螺絲、螺帽,至少套筒的攜帶比起整支開口(梅花)扳手的攜帶上要減少負重,可是對於D頭扳手的設置上缺忽略了一問題,那就是D頭在長期的驅動套筒旋轉時,與D頭相互鎖接的多邊形螺帽容易發生螺退的情況,導致D頭與旋蓋之間無法緊迫組合,甚至讓D頭無法在D頭扳手上穩固運作。故,相關業者必須思考該如何才可杜絕上述問題的發生。The above-mentioned D-head wrench is a common structural type on the market today, and the advantage of the D-head wrench is that the user does not have to deal with screws and nuts of different sizes like an open (torx) wrench, so that they have to carry it with them. Carrying multiple open (torx) wrenches with different opening sizes is both cumbersome and load-bearing. The D-head wrench only needs to be assembled with a universal wrench and sockets of different sizes to deal with screws and nuts of various sizes, at least The carrying of the socket is less load-bearing than the carrying of the whole open (torx) wrench. However, the lack of the setting of the D-head wrench has overlooked a problem, that is, the D-head will interact with the D-head when the socket is rotated for a long time. The interlocking polygonal nut caps are prone to screwing back, which makes it impossible to press the D head and the screw cap together, and even makes the D head unable to operate stably on the D head wrench. Therefore, the relevant industry must think about how to prevent the above problems from occurring.
本發明主要目的是提供D頭在轉動時,多邊形螺帽不會輕易的脫離,進而穩固D頭與旋蓋、D頭扳手之間的組配結合,其改善習知D頭扳手在D頭長時間的驅動下,以至於多邊形螺帽鬆脫於D頭,導致D頭產生鬆動等問題。然而,為了達到上述所說的功效並改善習知的缺失,本發明一種扳手迫緊裝置,其包括:一扳手本體,其一端裝設有一掣動組件,而該掣動組件包含有一D頭件,該D頭件一端係凸出於該扳手本體,另設有一軸心孔由該D頭件的一端貫穿至另一端,而該D頭件凸出於該扳手本體的一端之任一周側係設有一嵌孔連通該軸心孔;一軸心桿,其裝設於該D頭件的該軸心孔,而該軸心桿對應該嵌孔位置進一步凹設有一階槽,且該階槽區分有一深槽段及一淺槽段;一珠體,其裝設於該軸心桿的該階槽及該嵌孔之間,且該軸心桿於該軸心孔內升降位移時,該珠體位於該淺槽段時則受該軸心桿的推抵而局部凸露於嵌孔外,又該珠體位於該深槽段時則末入該深槽段內而未凸露於嵌孔外;一撥旋蓋,其裝設於該扳手本體且相反於該D頭件凸露的一端,該撥旋蓋於頂端向下凹設一容槽,且於該容槽槽底開設一穿孔,而該D頭件的頂端係凸出於穿孔而位於該容槽內;一螺片,其位於該容槽內並螺鎖於該D頭件,而該螺片與該D頭件之間的鎖合進一步形成至少一固接區,該至少一固接區的形成以固定該螺片及該D頭件之間的鎖接,且該螺片無法再相對該D頭件螺轉旋出;及一控壓組,其裝設於該撥旋蓋上並封蓋容槽且與該軸心桿相組合,且該控壓組於該撥旋蓋的容槽內位移而帶動該軸心桿於D頭件的軸心孔內位移;其中,透過該螺片與該D頭件之間的至少一固接區設置,使得該螺片無法再相對D頭件螺轉旋動,藉此得以穩固該D頭件裝設於該扳手本體而防止鬆動。The main purpose of the present invention is to provide that the polygonal nut will not be easily detached when the D head rotates, thereby stabilizing the assembly and combination between the D head and the screw cap and the D head wrench, which improves the length of the conventional D head wrench. Driven by time, the polygonal nut loosened on the D head, causing problems such as loosening of the D head. However, in order to achieve the aforementioned effect and improve the lack of the prior art, a wrench tightening device of the present invention includes: a wrench body, one end of which is equipped with a detent assembly, and the detent assembly includes a D head piece , One end of the D head piece protrudes from the wrench body, and another shaft hole is provided from one end of the D head piece to the other end, and the D head piece protrudes from either side of one end of the wrench body. An insert hole is provided to communicate with the axis hole; an axis rod is installed in the axis hole of the D head piece, and the axis rod is further recessed with a step groove corresponding to the position of the insertion hole, and the step groove Distinguish a deep groove section and a shallow groove section; a ball, which is installed between the step groove of the shaft rod and the insertion hole, and when the shaft rod moves up and down in the shaft hole, the When the bead is located in the shallow groove section, it is pushed by the shaft rod and partially protrudes out of the embedding hole. When the bead is located in the deep groove section, it will not enter the deep groove section without protruding from the embedding hole. Out of the hole; a dial screw cap, which is installed on the wrench body and opposite to the protruding end of the D head piece, the dial screw cap is recessed at the top end with a recess, and a recess is opened at the bottom of the recess Perforation, and the top end of the D head piece protrudes from the perforation and is located in the receiving groove; a screw piece located in the receiving groove and screwed to the D head piece, and the screw piece and the D head piece The interlocking further forms at least one fixing area, and the at least one fixing area is formed to fix the locking connection between the screw piece and the D head piece, and the screw piece can no longer be screwed relative to the D head piece Out; and a pressure control group, which is installed on the dial cap and covers the groove and is combined with the shaft rod, and the pressure control group is displaced in the groove of the dial cap to drive the shaft The mandrel is displaced in the axial hole of the D head piece; wherein, through at least one fixed area between the screw piece and the D head piece, the screw piece can no longer be screwed relative to the D head piece. This can stabilize the D head piece installed on the wrench body to prevent loosening.
根據上述說明,顯然該螺片與該D頭件之間的螺鎖利用該至少一固接區的設置,進而破壞該螺片及該D頭件頂端面,使得該螺片無法再螺轉卸除該D頭件,而又因該螺片無法再由D頭件上卸除,所以說該D頭件可以在該扳手本體上穩固的安裝,而不會有鬆動的問題發生,提供該D頭件更為穩固的操作使用。可見本發明可說是一種相當具有實用性及進步性之發明,相當值得產業界來推廣,並公諸於社會大眾。According to the above description, it is obvious that the screw lock between the screw and the D head piece uses the arrangement of the at least one fixing area, thereby destroying the screw piece and the top surface of the D head piece, so that the screw piece cannot be screwed and removed. In addition to the D head piece, and because the screw can no longer be removed from the D head piece, the D head piece can be firmly installed on the wrench body without loosening problems. Provide the D head piece. The headpiece is more stable for operation and use. It can be seen that the present invention can be said to be a very practical and progressive invention, which is worthy of being promoted by the industry and made public.
