In order to prevent the sparks generated when the grinding wheel and the workpiece are grinding from being sprayed towards the user with the centrifugal force of the rotation of the grinding wheel, the grinding wheel is equipped with a protective cover.

為了配合砂輪的研磨角度，護蓋通常是設計成可調整角度之結構。在習用技術當中，使用者必須要先利用工具(如螺絲起子)解除護蓋的固定狀態，才能進一步調整護蓋的角度。直到將護蓋調整到適當位置，再將護蓋予以鎖緊定位。因此，習用護蓋在結構方有改進之必要。In order to match the grinding angle of the grinding wheel, the cover is usually designed with an adjustable angle structure. In the conventional technology, the user must first use a tool (such as a screwdriver) to release the fixed state of the cover before further adjusting the angle of the cover. Until the cover is adjusted to a proper position, then the cover is locked and positioned. Therefore, there is a need for improvement in the structure of the conventional protective cover.

本新型在於提供一種砂輪機及其保護組件，藉以方便調整護蓋位置。The present invention is to provide a grinder and its protection assembly, so as to facilitate the adjustment of the position of the protective cover.

The mask portion 11 has two holes 114 . The hole 114 is located in the accommodating groove 113 and passes through the accommodating groove 113 on the first surface 111 and the second surface 112 . The transmission element 13 is provided with a grinding wheel 5 , and the grinding wheel 5 is pivotally mounted on the transmission element 13 .

護蓋2位於第二表面112遠離第一表面111之一側，且可依傳動元件13之軸相對於機體1轉動。護蓋2包含一頂罩部21、一底罩部22以及一側罩部23。頂罩部21具有一弧型滑槽211。底罩部22位於頂罩部21遠離遮罩之一側。側罩部23之兩側分別與頂罩部21與底罩部22相連。在砂輪5研磨工件時，護蓋2可以防止研磨碎屑及火花濺射至使用者。The protective cover 2 is located on a side of the second surface 112 away from the first surface 111 , and can rotate relative to the body 1 according to the axis of the transmission element 13 . The cover 2 includes a top cover portion 21 , a bottom cover portion 22 and a side cover portion 23 . The top cover portion 21 has an arc-shaped sliding slot 211 . The bottom cover part 22 is located on a side of the top cover part 21 away from the cover. Two sides of the side cover portion 23 are respectively connected to the top cover portion 21 and the bottom cover portion 22 . When the grinding wheel 5 grinds the workpiece, the protective cover 2 can prevent grinding debris and sparks from splashing to the user.

固定組件3包含一卡固元件31、一連結元件32以及二彈性元件33。卡固元件31包含一卡合片311以及二空心柱312。卡合片311位於護蓋2遠離遮罩部11之一側，使護蓋2至少部分位於遮罩部11與卡合片311之間。空心柱312突起於卡合片311，並往接近遮罩部11的方向延伸。連結元件32包含一第一柱體321以及二第二柱體322。第二柱體322位於孔114，且第二柱體322之兩端部分別插設於第一柱體321及空心柱312。彈性元件33套設於第二柱體322。彈性元件33之相對兩端分別抵靠遮罩部11以及空心柱312。The fixing component 3 includes a fastening element 31 , a connecting element 32 and two elastic elements 33 .

The engaging piece 311 is located on a side of the cover 2 away from the cover portion 11 , so that the cover 2 is at least partially located between the cover portion 11 and the engaging piece 311 . The hollow column 312 protrudes from the engaging piece 311 and extends towards the direction approaching the cover portion 11 . The connection element 32 includes a first column 321 and two second columns 322 . The second cylinder 322 is located in the hole 114 , and two ends of the second cylinder 322 are respectively inserted into the first cylinder 321 and the hollow cylinder 312 . The elastic element 33 is sleeved on the second cylinder 322 . Two opposite ends of the elastic element 33 abut against the cover portion 11 and the hollow post 312 respectively.

切換件4包含一樞設部41以及一操控部42。在本實施例中，樞設部41位於容置溝槽113，且與第一柱體321樞接。樞設部41具有一背對第一柱體軸心R1之外周面，外周面具有一第一抵靠面411以及一第二抵靠面412。第一抵靠面411與第一柱體軸心R1有一第一距離D1。第二抵靠面412與第一柱體軸心R1有一第二距離D2。第一距離D1大於第二距離D2。換句話說，樞設部41是利用偏心樞設的方式設於第一柱體321，且使第一柱體軸心R1與槽底面1131之距離隨著樞設部41樞轉而變化。操控部42與樞設部41相連，並用以帶動樞設部41相對第一柱體321樞轉。The switching member 4 includes a pivot portion 41 and a control portion 42 . In this embodiment, the pivoting portion 41 is located in the accommodating groove 113 and is pivotally connected to the first post 321 . The pivoting portion 41 has an outer peripheral surface facing away from the axis R1 of the first cylinder, and the outer peripheral surface has a first abutting surface 411 and a second abutting surface 412 . The first abutting surface 411 has a first distance D1 from the axis R1 of the first cylinder. The second abutting surface 412 has a second distance D2 from the axis R1 of the first cylinder. The first distance D1 is greater than the second distance D2. In other words, the pivoting portion 41 is eccentrically pivotally disposed on the first cylinder 321 , and the distance between the axis R1 of the first cylinder and the bottom surface 1131 of the groove changes as the pivoting portion 41 pivots. The control part 42 is connected to the pivot part 41 and used to drive the pivot part 41 to pivot relative to the first cylinder 321 .

在本實施例中，操控部42包含一第一部分421、二第二部分422以及二第三部分423。第一部分421連接於樞設部41，並向遮罩部11往握把部12接近之方向延伸。二第二部分422分別與第一部分421連接之相對兩側並往護蓋2方向延伸。二第三部分423分別與二第二部分422遠離第一部分421之一側連接。定義一第一基準面E1，且第一基準面E1的法線與第二柱體軸心R2平行，以及第一基準面E1與握把部12遠離護蓋2的一側相切。定義一第二基準面E2，且第二基準面E2的法線與第二柱體軸心R2平行，以及第二基準面E2與握把部12接近護蓋2的一側相切。第三部分423位於第一基準面E1以及第二基準面E2之間，並往握把部12外周面背向軸心的方向延伸。二組第二部分422以及第三部分423的組合對稱於第一部分421。In this embodiment, the manipulation part 42 includes a first part 421 , two second parts 422 and two third parts 423 . The first portion 421 is connected to the pivot portion 41 and extends toward the direction in which the cover portion 11 approaches the handle portion 12 . The two second parts 422 are respectively connected to opposite sides of the first part 421 and extend toward the protective cover 2 . The two third parts 423 are respectively connected to one side of the two second parts 422 away from the first part 421 . A first reference plane E1 is defined, and the normal line of the first reference plane E1 is parallel to the axis R2 of the second cylinder, and the first reference plane E1 is tangent to the side of the handle portion 12 away from the cover 2 . A second reference plane E2 is defined, and the normal line of the second reference plane E2 is parallel to the axis R2 of the second cylinder, and the second reference plane E2 is tangent to the side of the handle portion 12 close to the cover 2 . The third portion 423 is located between the first datum plane E1 and the second datum plane E2 , and extends toward the outer peripheral surface of the handle portion 12 away from the axis. The combination of the two sets of the second part 422 and the third part 423 is symmetrical to the first part 421 .

由於第三部分423向握把部12外周面背向軸心的方向延伸，因此可以讓使用者方便撥動切換件4。Since the third portion 423 extends toward the outer peripheral surface of the handle portion 12 in a direction away from the axis, it is convenient for the user to toggle the switching member 4 .

請參閱圖4至圖5。圖4為圖1中的砂輪機之切換件位於釋放位置時的局部作動示意圖。圖5為圖1中的砂輪機之切換件位於釋放位置時的局部剖面圖。See Figures 4 through 5. FIG. 4 is a schematic diagram of the partial action of the switching member of the grinder in FIG. 1 when it is at the release position. Fig. 5 is a partial cross-sectional view of the switching member of the grinder in Fig. 1 when it is in the release position.

在本實施例中，切換件4可相對機體1沿F1方向轉動而位於一定位位置，或可相對機體1沿3方向至一釋放位置。當切換件4位於定位位置時，第一抵靠面411與遮罩部11接觸，使第一柱體軸心R1與槽底面1131距離為第一距離D1。此時連結元件32帶動卡合片311沿F2方向移動接近機體1，令卡合片311與機體1可以夾合護蓋2。此時彈性元件33被壓縮。當切換件4位於釋放位置時，第二抵靠面412與機體1接觸，使第一柱體軸心R與槽底面1131距離為第二距離D2。此時連結元件32帶動卡合片311沿F5方向移動遠離機體1，並解除卡合片311與機體1對護蓋2的夾合關係而令護蓋2可相對機體1沿F4方向或沿與F4相反的方向轉動。此時彈性元件33自壓縮狀態釋放。換句話說，因為切換件4偏心樞設於連結元件32，所以當切換件4於定位位置以及釋放位置擺動時，第一柱體軸心R1與容置溝槽113的距離會產生變化。第一柱體軸心R1與與槽底面1131的距離變化帶動連結元件32上下移動，進而帶動卡合片311與機體1夾合護蓋2或是釋放夾合力。In this embodiment, the switching member 4 can be rotated relative to the body 1 along a direction F1 to be located at a positioning position, or can be moved relative to the body 1 to a release position along a direction 3 . When the switching member 4 is at the positioning position, the first abutting surface 411 contacts the mask portion 11 , so that the distance between the first column axis R1 and the groove bottom surface 1131 is a first distance D1 . At this time, the connecting element 32 drives the engaging piece 311 to move close to the body 1 along the F2 direction, so that the engaging piece 311 and the body 1 can clamp the protective cover 2 . At this time the elastic element 33 is compressed. When the switching member 4 is at the release position, the second abutting surface 412 is in contact with the machine body 1 , so that the distance between the axis R of the first cylinder and the bottom surface 1131 of the groove is a second distance D2 . At this time, the connecting element 32 drives the engaging piece 311 to move away from the body 1 along the F5 direction, and releases the clamping relationship between the engaging piece 311 and the body 1 to the protective cover 2 so that the protective cover 2 can be moved relative to the body 1 along the F4 direction or along with the body 1. F4 turns in the opposite direction. At this time, the elastic element 33 is released from the compressed state. In other words, because the switching member 4 is eccentrically pivoted on the connecting member 32 , when the switching member 4 swings between the positioning position and the releasing position, the distance between the first cylinder axis R1 and the receiving groove 113 will change. The change of the distance between the axis R1 of the first cylinder and the bottom surface 1131 of the groove drives the connecting element 32 to move up and down, and further drives the engaging piece 311 to clamp the cover 2 with the body 1 or release the clamping force.

護蓋2可以經切換件4作動於固定狀態以及可移動狀態，進而達成不使用其他工件調整護蓋2的目的。護蓋2可以配合砂輪5的研磨角度調整位置，令使用者可以在不同的研磨角度作業且受護蓋2保護。The protective cover 2 can be actuated into a fixed state and a movable state through the switching member 4 , so as to achieve the purpose of adjusting the protective cover 2 without using other workpieces. The position of the protective cover 2 can be adjusted according to the grinding angle of the grinding wheel 5 , so that the user can work at different grinding angles while being protected by the protective cover 2 .

由於第三部分423位於第一基準面E1以及第二基準面E2之間，因此可以避免操作時，操控部42被外物撞擊離開定位位置。Since the third portion 423 is located between the first datum plane E1 and the second datum plane E2 , it is possible to prevent the manipulating part 42 from being knocked out of the positioning position by foreign objects during operation.

在本實施例中，遮罩部11具有一容置溝槽113。在其他實施例中，遮罩部也可以是不具容置溝槽的平面。再於其他實施例中，樞設部也可位於不具溝槽的面。只需位於機體遠離護蓋之一側，並與機體相連。再於其他實施例中，握把部與遮罩部也可為一體成形或其他連結關係，例如：黏合、鎖固，但不以此為限。In this embodiment, the mask portion 11 has a receiving groove 113 . In other embodiments, the mask portion may also be a plane without receiving grooves. In other embodiments, the pivoting portion can also be located on the surface without the groove. It only needs to be located on the side of the body away from the cover and connected to the body. In other embodiments, the handle portion and the cover portion can also be integrally formed or connected in other ways, such as bonding and locking, but not limited thereto.

In other embodiments, the arc-shaped chute may not be located at the bottom cover, but may be located at the side cover or the top cover. In other embodiments, instead of a chute structure, it may be, for example, a slide rail, but it is not limited thereto.

在本實施例中，孔114位於容置溝槽113。在其他實施例中，孔可以不位於容置溝槽內，可以位於例如：第一表面，但不以此為限。In this embodiment, the hole 114 is located in the receiving groove 113 . In other embodiments, the hole may not be located in the accommodating groove, but may be located, for example, on the first surface, but not limited thereto.
