Description of the Invention: [Technical Field of the Invention] In particular, the invention relates to a structure of a combustion type power tool of a combustion type power tool. [Prior Art], the burning power tool such as the burning nailer 1 is mainly used to ignite the pain in the combustion chamber, the second gas and the fuel, so that the gas is heated and the volume is expanded to push the cylinder. The piston, (4) nail or screw is picked into the working part. At the same time, the gas of the steam is discharged to the outside, so that the piston can be reset. Therefore, the general combustion type power tools are designed with exhaust ports on the steam rainbow, and in order to avoid external dust and other pollution, the exhaust gas D enters the cylinder, and the reeds are provided with reeds and reeds. The check valve consists of a plate that allows the gas to be discharged only outward. In other words, when the gas pressure in the steam rainbow is in line with the willingness of the outside world, it will close in one direction. Further, the cylinder is disposed on the cylinder at a position corresponding to the one-way _, and an exhaust cover is disposed over the exhaust port. One end of the venting cap is screwed to the cylinder, and the other end is fixed to the reed plate. In addition to the solid (4) gas cover, it is also used to limit the vibration amplitude of the exhaust cover when it is exhausted. The venting cap—directs the direction of the airflow, and on the other hand limits the extent to which the reed of the one-way valve opens during venting, avoiding excessive opening of the reed, which affects the reliability of the one-way valve over time. However, after each gas combustion expansion pushes the piston, the gas is discharged from the exhaust port through the one-way valve, wherein the gas flowing through the reed plate causes vibration of the exhaust cover, and long-term vibration easily causes the exhaust cover to be fixed. The foot is broken such that one end of the vent cap assumes an unfixed state. After the fixed foot of the venting cover is broken, not only the venting cover has a greater amplitude of vibration in each venting, but also the opening of the reed is unrestricted and the opening is larger, which affects the reliability of the reed. . : This requires a combustion power tool structure that can make the vent cover vibrate when it is shaken to prevent the vent cover from breaking to extend the life of the vent cover. In turn, the reliability of the check valve is maintained. SUMMARY OF THE INVENTION In summary, the present invention provides a combustion type power worker.

According to the above aspect of the invention, a combustion type power tool structure is proposed, comprising a housing T, a cylinder, an exhaust cover, a fixing member and a pressing member. The cylinder is located in the casing, and the cylinder has an exhaust gas exhaust cover that covers the outside of the exhaust port. The component is located at the end of the venting cap to secure the venting cap to the cylinder. The abutment is located on the inside of the housing to resist the venting cover. Another aspect of the present invention provides a combustion power tool structure in which a protrusion on a venting cap abuts against a casing to control the amplitude of the vent cover vibration to avoid breakage of the vent cap. situation. According to the above aspect of the invention, a combustion type power tool structure is proposed, which comprises a casing, a steam red, a venting cover, a comparative member and a protruding portion. The cylinder is located within the housing and the cylinder has an exhaust port. The exhaust cover covers the exhaust port of the cylinder, and the exhaust cover has a lock hole at one end, and the exhaust cover of the adjacent lock hole has a fixed leg on both sides. The fixing member is fixed to the steam rainbow through the locking hole of the exhaust cover. The protruding portion is integrally formed on the exhaust cover, and the protruding portion abuts against the inner surface of the housing. :* Applying the structure of the combustion type power tool of the present invention, the amplitude of the vibration of the exhaust cover is limited by the protrusion on the casing or the protrusion on the exhaust cover, and the exhaust cover can be prevented from being broken. The gap between the exhaust cover and the housing is reduced, but does not affect the exhaust area and the installation of the combustion power tool. [Embodiment] At present, the limitation of the vent cover vibration mass production & ^ a field is mostly between the housing and the exhaust cover.
的間隙縮小，也就是直接使排氣蓋的震動空間縮小來限制排氣 蓋的震動幅度’避免排氣蓋斷裂。然而，若殼體與排氣蓋間的 間隙縮的不夠，則無法達到限制排氣蓋震動的幅度。反之，若 將殼艎與排氣蓋間的間隙縮的太小，完全限制排氣蓋的震動幅 度則又會，衫響氣體排放的載面積，進而影響氣體排放的效 果，也會增加組立的困難。 另外的作法是增加排氣蓋固定腳的寬度或數量，然而固定 腳的寬度或數量的增加相對會減少氣體的排氣面積，影響氣體 排放的效[又-種限㈣氣蓋震動幅度的作法為直接增加排 氣蓋的厚度與重量，使排氣蓋較不容易震動。，然而，增加排氣 蓋的重量也相對增加整個燃燒式動力工具的重量，進而造成使 用者操作上的不方便。 有鑑於上述問題，在本發明的實施例中提出一種燃燒式動 力工具結構，利用抵件抵住排氣蓋，以限制排氣蓋的震動幅度。 凊參照第1圖，其繪示依照本發明一實施例的一種燃燒式 動力工具結構側面剖示圖。燃燒式動力工具結構包含殼體 U〇、汽叙120、排氣蓋130、固定件140與抵件150。 汽缸120設置於殼體11〇内，於汽缸12〇上具有排氣口 122 ’而排氣口 122處設置有排氣板124、簧片板125與簧片 126。 201026455 第2圖為繪示第1圖不包含抵件之燃燒式動力工具結構的 立體分解圖。請同時參照第！圖及第2圖。排氣板124置於簧 片板125與汽缸12〇間，而簧片板125上則設有簧片126，並 於女片126上罩覆排氣蓋丨3〇。因此，於燃燒式動力工具受熱 瞬間體積膨脹進而推動汽缸12〇中之活塞128時，簧片126會 因汽缸120内之氣體壓力大於外界而開啟，使氣體排出，活塞 128得以復位。而當汽缸12〇内之氣體壓力與外界壓力相同時， 簧片126即會關閉，停止氣體排放。 籲 換句話說，如第1圖所示，排氣蓋130即相對罩覆於排氣 口 122外。請參照第3圖，其係繪示第i圖中排氣蓋之立體示 意圖。排氣蓋130 —端具有鎖孔132，相鄰鎖孔132之排氣蓋 130兩侧及相對於鎖孔132的排氣蓋13〇對邊皆具有固定腳 134 〇 如第2圖所示，固定件14〇為螺絲，其穿過排氣蓋13〇之 鎖孔132、簧片I26及簧片板125之一端，一併將排氣蓋130、 普片126及簧片板125固定於汽缸12〇上。而排氣蓋之固定腳 Ο Π4則可嵌入簧片板125以將排氣蓋130另一端固定。另外， 簧片板125另一端則以螺絲129固定於汽缸上。由於燃燒式動 力工具作動時，汽缸120中的氣體壓力大於外界，因此每一次 氣體通過排氣口排放時，皆會造成排氣蓋13〇震動。 如第1圖所示，抵件150位於殼體11〇之内面，相對位於 排氣蓋130上方。抵件150可為由殼體11〇延伸出之凸肋，抵 於排氣蓋130上。第4圖係繪示第1圖燃燒式動力工具結構之 正面剖示圖。請同時參照第丨圖與第4圖，於此實施例中，抵 件15〇為一個凸肋，位於排氣蓋130具有固定腳134 一端之上 方。以抵件150與排氣蓋13〇之固定腳134共同限制排氣蓋13〇 201026455 的震動幅度。或者，抵件150也可為數個凸肋或凸塊，位於排 氣蓋130具有固定腳134 一端上之兩側。上述抵件15〇之位置 僅為舉例，抵件15〇可位於殼體上相對排氣蓋之適當位置。 此外，抵件150與排氣蓋13〇間具有空隙，使得燃燒式動 力工具排氣時，排氣蓋13〇仍然有震動的空間以增加排氣面 積彳-又因有抵件150抵於排氣蓋130上方，所以排氣蓋13〇 的震動空間受到限制，而不會過度拉扯固定腳134，進而造成 固定腳U4斷裂。也因此於排氣時，排氣口 122上之簧片126 _的打開幅度可完全的受到排氣蓋13〇之限制，就算長期使用也 不會影響簧片126的可靠度。 另外，由於燃燒式動力工具主要為氣體受熱瞬間體積膨脹 進而推動汽缸中之活塞，每一次的作動皆會發出***聲響。因 此，如第1圖所示，排氣蓋130内之固定腳134端可設置吸音 棉160，以降低燃燒式動力工具作動時所發出之聲響。 第5圖係繪示依照本發明另一實施例的燃燒式動力工具結 構之側面剖示圖。如第5圖所示，燃燒式動力工具結構同樣包 © 含有殼體210、汽缸220、排氣蓋230、固定件240與抵件250。 所有結構皆與前述實施例相似，差別在於燃燒式動力工具結構 中具有抵件250位於排氣蓋230上方，因此排氣蓋230僅以固 定件240固定於汽缸220上，排氣蓋23〇不具有固定腳。而在 此燃燒式動力工具結構中僅以抵件25〇限制排氣蓋23〇的震動 幅度。 第6圖係繪示依照本發明又一實施例的燃燒式動力工具結 構之側面剖示圖。如第6圖所示，燃燒式動力工具結構包含殼 體310、汽缸320、排氣蓋330、突出部336與固定件340。此 實施例中之汽缸320以及固定件34〇與前述實施例相同，不在 201026455 此重複描述。 排氣蓋330則罩覆於排氣口 322外。第7圖係繪示第6圖 中排氣蓋之立體示意圖。如第7圖所示，排氣蓋330 —端具有 鎖孔332，而相鄰鎖孔332之排氣蓋330兩側以及排氣蓋鎖孔 332之對邊皆具有固定腳334。排氣蓋330上具有一體成型之 突出部336。如第7圖所示，突出部336為一凸塊，位於排氣 蓋330上。或者，突出部336也可為一個或數個凸肋，跨於排 氣蓋330上，亦或是突出部336為數個凸塊，位於排氣蓋330 ❿ 具有固定腳334 —端上之兩側。上述突出部350之位置僅為舉 例，突出部336可位於排氣蓋上適當位置。當排氣蓋330因排 氣而震動時，排氣蓋330之突出部336便會抵頂於殼體310之 内面，而限制排氣蓋330之震動幅度。 請參照第6圖。突出部336與殼體310間具有空隙。於燃 燒式動力工具排氣時，排氣蓋330仍然有震動的空間以增加排 氣面積，但突出部336可抵頂於殼體310之内面，使得突出部 336可與固定腳334共同限制排氣蓋330之震動幅度，而不會 φ 過度拉扯固定腳334，進而造成固定腳334斷裂。 利用本發明之燃燒式動力工具結構的優點在於： 第一，殼體與排氣蓋間具有抵件，或是排氣蓋上具有突出部， 可限制排氣蓋於燃燒室動力工具排氣時的震動幅度，但不會影響 使用者組立與使用燃燒室動力工具。 第二，抵件與排氣蓋間或突出部與殼體間仍具有間隙。因此， 排氣蓋的震動幅度雖然受到限制，但仍有一定的可震動幅度，以 增加排氣面積。 第三，由於排氣蓋的震動幅度受到限制，可避免排氣蓋因長 201026455 期震動而過度拉扯固定腳，造成固定腳斷裂。因此可使得排氣口 上之簧片也受到保護，減少排氣蓋與簧片的損耗。 雖然本發明已以諸實施例揭露如上，然其並非用以限定本發 明，任何熟習此技藝者，在不脫離本發明之精神和範圍内，當可 作各種之更動與满飾。因此本發明之保護範圍當視後附之申^專 利範圍所界定者為準。 【圖式簡單說明】 為讓本發明之上述和其他目的、特徵、優點與實施例能更明 顯易懂，所附圖式之說明如下： 第1圖係繪示依照本發明一實施例的一種燃燒式動力工具 結構側面剖示圖。 第2圖係緣示第！圖不包含抵件之燃燒式動力工具結構的 立體分解圖。 第3圖係繪示第！圖中排氣蓋之立體示意圖。 第4圖係緣示第j圖燃燒式動力工具結構之正面剖示圖。 第5圖係繪示依照本發明另一實施例的燃燒式動力工具結 構之側面剖示圖。 第6圖係繪不依照本發明又一實施例的燃燒式動力工具結 構之侧面剖示圖。 'η 第7圖係繪示第6圖中排氣蓋之立體示意圖。 【主要元件符號說明】 120 :汽缸 124 :排氣板 Η〇 :殼體 122 :排氣口 201026455 125 :簧片板 126 ： 128 :活塞 129 ： 130 :排氣蓋 132 ： 134 :固定腳 140 ： 150 :抵件 160 ： 210 :殼體 220 : 230 :排氣蓋 240 : 250 :抵件 310 : 320 :汽缸 330 ： 332 :鎖孔 334 ： 336 :突出部 340 簧片 螺絲 鎖孔 固定件 吸音棉 汽缸 固定件 殼體 排氣蓋 固定腳 固定件The gap is reduced, that is, the vibration space of the exhaust cover is directly reduced to limit the vibration amplitude of the exhaust cover to avoid the breakage of the exhaust cover. However, if the gap between the casing and the vent cover is insufficiently reduced, the extent to which the vent cover is shaken cannot be achieved. On the other hand, if the gap between the casing and the exhaust cover is shrunk too small, the vibration amplitude of the exhaust cover will be completely limited, and the load area of the gas discharge will affect the effect of the gas discharge, and the assembly will also be increased. difficult. Another method is to increase the width or the number of fixing feet of the exhaust cover. However, the increase of the width or the number of the fixed feet will relatively reduce the exhaust area of the gas, and affect the effect of the gas discharge [again-limit (four) gas cover vibration amplitude] In order to directly increase the thickness and weight of the exhaust cover, the exhaust cover is less likely to vibrate. However, increasing the weight of the exhaust cover also increases the weight of the entire combustion type power tool, thereby causing inconvenience to the user. In view of the above problems, in the embodiment of the present invention, a combustion type power tool structure is proposed in which the damper cover is pressed against the vent cover to limit the vibration amplitude of the vent cover. Referring to Figure 1, there is shown a side cross-sectional view of a structure of a combustion power tool in accordance with one embodiment of the present invention. The combustion power tool structure includes a housing U〇, a steam stop 120, an exhaust cover 130, a fixing member 140 and a resisting member 150. The cylinder 120 is disposed in the casing 11b, has an exhaust port 122' on the cylinder 12'', and a discharge plate 124, a reed plate 125, and a reed 126 are disposed at the exhaust port 122. 201026455 Fig. 2 is an exploded perspective view showing the structure of the combustion type power tool which does not include the abutment in Fig. 1. Please refer to the same at the same time! Figure and Figure 2. The venting plate 124 is disposed between the reed plate 125 and the cylinder 12, and the reed plate 125 is provided with a reed 126, and the female 126 is covered with a venting cover 丨3〇. Therefore, when the combustion power tool is heated and the volume is expanded to push the piston 128 in the cylinder 12, the reed 126 is opened because the gas pressure in the cylinder 120 is greater than the outside, so that the gas is discharged and the piston 128 is reset. When the gas pressure in the cylinder 12 is the same as the external pressure, the reed 126 is closed to stop the gas discharge. In other words, as shown in Fig. 1, the exhaust cover 130 is opposed to the outside of the exhaust port 122. Please refer to Fig. 3, which is a perspective view showing the exhaust cover of Fig. i. The exhaust cover 130 has a locking hole 132 at its end, and the exhaust cover 130 of the adjacent locking hole 132 and the exhaust cover 13 opposite to the locking hole 132 have a fixing leg 134 opposite to the locking hole 132, as shown in Fig. 2, The fixing member 14 is a screw which passes through one of the locking hole 132 of the exhaust cover 13 , the reed I26 and the reed plate 125 , and fixes the exhaust cover 130 , the plate 126 and the reed plate 125 to the cylinder 12 〇. The fixed foot Π4 of the venting cover can be embedded in the reed plate 125 to fix the other end of the venting cover 130. In addition, the other end of the reed plate 125 is fixed to the cylinder by a screw 129. Since the gas pressure in the cylinder 120 is greater than the outside when the combustion type power tool is actuated, each time the gas is discharged through the exhaust port, the exhaust cover 13 is vibrated. As shown in Fig. 1, the abutting member 150 is located on the inner surface of the casing 11 and is located above the exhaust cover 130. The abutting member 150 may be a rib extending from the casing 11 to abut against the vent cover 130. Fig. 4 is a front cross-sectional view showing the structure of the combustion type power tool of Fig. 1. Referring to both the first and fourth figures, in this embodiment, the abutting member 15 is a rib located above the one end of the vent cover 130 having the fixed leg 134. The resisting member 150 and the fixing leg 134 of the exhaust cover 13 are collectively limited to the vibration amplitude of the exhaust cover 13 〇 201026455. Alternatively, the abutting member 150 may be a plurality of ribs or projections on both sides of the exhaust cap 130 having one end of the fixing leg 134. The position of the abutting member 15 is merely an example, and the abutting member 15 can be located at an appropriate position on the casing relative to the exhaust cover. In addition, there is a gap between the abutting member 150 and the exhaust cover 13〇, so that when the combustion type power tool is exhausted, the exhaust cover 13〇 still has a space for vibration to increase the exhaust area 彳-and because the resisting member 150 is in contact with the row Above the gas cap 130, the vibration space of the exhaust cap 13〇 is restricted without excessively pulling the fixing leg 134, thereby causing the fixing leg U4 to break. Therefore, when the exhaust gas is exhausted, the opening width of the reed 126_ on the exhaust port 122 can be completely restricted by the exhaust cover 13〇, and the reliability of the reed 126 is not affected even if it is used for a long period of time. In addition, since the combustion type power tool mainly expands the volume of the gas in an instant and then pushes the piston in the cylinder, a blasting sound is emitted every time the operation is performed. Therefore, as shown in Fig. 1, the sound absorbing cotton 160 may be provided at the end of the fixing leg 134 in the venting cover 130 to reduce the sound of the burning power tool when it is actuated. Figure 5 is a side cross-sectional view showing the structure of a combustion power tool in accordance with another embodiment of the present invention. As shown in FIG. 5, the combustion power tool structure also includes a housing 210, a cylinder 220, an exhaust cover 230, a fixing member 240, and a resisting member 250. All the structures are similar to the previous embodiment except that the abutting member 250 is located above the exhaust cover 230 in the combustion power tool structure, so that the exhaust cover 230 is only fixed to the cylinder 220 by the fixing member 240, and the exhaust cover 23 is not Has a fixed foot. In this combustion type power tool structure, only the contact member 25 〇 limits the vibration amplitude of the vent cover 23 。. Figure 6 is a side cross-sectional view showing the structure of a combustion type power tool in accordance with still another embodiment of the present invention. As shown in Fig. 6, the combustion power tool structure includes a housing 310, a cylinder 320, a vent cover 330, a projection 336, and a fixture 340. The cylinder 320 and the fixing member 34 in this embodiment are the same as the foregoing embodiment, and are not repeatedly described in 201026455. The exhaust cover 330 is overlaid outside the exhaust port 322. Fig. 7 is a perspective view showing the exhaust cover of Fig. 6. As shown in Fig. 7, the exhaust cover 330 has a lock hole 332 at its end, and the opposite sides of the exhaust cover 330 of the adjacent lock hole 332 and the opposite sides of the vent cover lock hole 332 have fixing legs 334. The vent cover 330 has an integrally formed projection 336 thereon. As shown in Fig. 7, the projection 336 is a projection located on the vent cover 330. Alternatively, the protrusions 336 may also be one or several ribs, spanning the vent cover 330, or the protrusions 336 may be a plurality of bumps on the sides of the vent cover 330 ❿ having the fixed legs 334 . The position of the above-mentioned projections 350 is only an example, and the projections 336 may be located at appropriate positions on the exhaust cover. When the vent cover 330 vibrates due to exhaust, the projection 336 of the vent cap 330 abuts against the inner surface of the housing 310, and limits the amplitude of the shock of the vent cover 330. Please refer to Figure 6. There is a gap between the protrusion 336 and the housing 310. When the combustion power tool is exhausted, the exhaust cover 330 still has a space for vibration to increase the exhaust area, but the protrusion 336 can abut against the inner surface of the housing 310, so that the protrusion 336 can be restrained together with the fixed leg 334. The vibration amplitude of the gas cap 330 does not excessively pull the fixing leg 334, thereby causing the fixing leg 334 to break. The advantage of using the combustion type power tool structure of the present invention is that: first, there is a contact between the casing and the exhaust cover, or there is a protrusion on the exhaust cover to limit the exhaust cover when the power tool of the combustion chamber is exhausted. The magnitude of the vibration, but does not affect the user's ability to assemble and use the combustion chamber power tool. Second, there is still a gap between the abutting member and the venting cover or between the protruding portion and the housing. Therefore, although the vibration amplitude of the exhaust cover is limited, there is still a certain vibration amplitude to increase the exhaust area. Third, because the vibration amplitude of the exhaust cover is limited, it is possible to prevent the exhaust cover from excessively pulling the fixed foot due to the long-term vibration of the 201026455 period, causing the fixed foot to break. Therefore, the reed on the exhaust port can also be protected, reducing the loss of the exhaust cover and the reed. While the invention has been described above by way of example, it is not intended to limit the invention, and the invention may be modified and varied. Therefore, the scope of the invention is defined by the scope of the appended claims.
