Description

雙滑套測試桿Double slide test rod

本創作係涉及一種耐用性測試裝置,尤指一種用於按壓式按鍵的測試桿。This creation relates to a durability test device, and more particularly to a test lever for a push button.

3C產品已經成為現代人生活的一部份,而物品的耐用性也儼然成為各品牌指標性的競爭數據。在鍵盤、滑鼠以及各式各樣以按壓式按鍵作為主要操作方式的產品裡,按鍵的壽命,即為按鍵最大可承受的按壓次數,就是判斷該產品的耐用性的最佳數據。而按壓次數的測試方式,是以機台使測試桿快速地上下移動並撞擊產品的按鍵再記錄該數據。3C products have become a part of modern life, and the durability of the items has become an index of competitive data for each brand. In keyboards, mice, and a variety of products that use push-buttons as the primary mode of operation, the life of the button, which is the maximum number of presses the button can withstand, is the best data to determine the durability of the product. The test method of the number of presses is to record the data by pressing the button of the machine to move the test rod up and down quickly and hit the product.

Referring to FIG. 13, the test rod of the prior art has a sleeve 90, a rod 91, two sleeves 92, a spring 93, and a probe 94. The tube 90 is connected to the machine table and moves up and down with the machine table; the measuring rod 91 is relatively movably disposed in the sleeve 90, and the outer wall surface of the measuring rod 91 is surrounded by an abutting portion 911; the two sleeves 92 are fixedly fixed to The sleeve 90 is adjacent to both ends of the sleeve 90; the spring 93 abuts between the upper sleeve 92 and the abutting portion 911 of the spindle 91; the probe 94 is disposed at the bottom end of the spindle 91.

使用時,機台帶動整個測試桿向下移動,測桿91下方的測頭94撞擊並按壓按鍵,在按壓過程中測桿91因按鍵本身的回彈力道而相對於套管90向上移動,並且壓縮彈簧93。這樣的設計可以使機台在按鍵的行程結束後能有一個潰縮的機制而不會損壞鍵盤,且也能以改變彈簧93的預載或彈力來測試按鍵的回彈力道,但是因為本身的結構設計,使得現有技術中的測試桿的性能因下列的缺點而稍有打折。In use, the machine moves the entire test rod downward, and the probe 94 below the rod 91 hits and presses the button, and the rod 91 moves upward relative to the sleeve 90 due to the resilient force of the button itself during pressing, and Compression spring 93.

Such a design may cause the movement to be unsmooth due to the frictional force, and the wear time may cause wear after being elongated. Its own durability problem.

第二,彈簧93在壓縮過程中會有些許左右偏擺,進而摩擦套管90的內壁面以及測桿91而造成磨耗與不順暢,且彈簧93的長度越長,則偏擺的幅度越大。Secondly, the spring 93 may have a slight yaw during the compression process, thereby rubbing the inner wall surface of the sleeve 90 and the measuring rod 91 to cause wear and tear, and the longer the length of the spring 93, the greater the yaw amplitude. .

The above load adjusting member 81 and the rubber ring 82 are designed to adjust the relative position of the slide bar 30 and the sleeve 10 and further adjust the preload of each spring, but the present invention may not include the load adjusting member 81 and the rubber ring 82. .

請參閱圖10所示,本創作的第二實施例中進一步包含有一外彈簧50A,其套設於滑桿30A外,且外彈簧50A之兩端分別抵靠於下端套22A以及按壓頭70A,用以增加整體回彈力道。此外,也可使下端套22A形成有一凸緣222A位於套管外,且曾設一外端套20A並使其形成有一凸緣21A,而外彈簧50A之兩端係套設固定於相對應的各凸緣222A、21A,用以更加穩固,但並不以此為限。Referring to FIG. 10, the second embodiment of the present invention further includes an outer spring 50A that is sleeved outside the sliding bar 30A, and the two ends of the outer spring 50A abut against the lower end sleeve 22A and the pressing head 70A, respectively. Used to increase the overall resilience. In addition, the lower end sleeve 22A may be formed with a flange 222A outside the sleeve, and an outer end sleeve 20A is provided and formed with a flange 21A, and both ends of the outer spring 50A are sleeved and fixed. Each of the flanges 222A, 21A is used for more stability, but is not limited thereto.

請參閱圖11及圖12所示,在本創作的第三實施例中,下端套22B的外壁面環繞突出形成一外環部221B,外環部221B位於套管10B的下方,且向上抵靠套管10B的底端,用以增加向上的支撐力,但是下端套22B也可以沒有外環部221B,如前兩實施例所示。Referring to FIG. 11 and FIG. 12, in the third embodiment of the present invention, the outer wall surface of the lower end sleeve 22B is circumferentially protruded to form an outer ring portion 221B, and the outer ring portion 221B is located below the sleeve 10B and abuts upward. The bottom end of the sleeve 10B is used to increase the upward supporting force, but the lower end sleeve 22B may also have no outer ring portion 221B as shown in the first two embodiments.

本創作在使用時,圖9所示,套管10的外壁面螺合於固定件A,且固定件A連接於機台B,藉此本創作即可隨著機台B上下移動。而當本創作向下抵靠於被測試按鍵時,因被測試按鍵本身的回彈力道又或者是被測試按鍵本身的行程結束,按壓頭70受一向上抵靠的力而帶動滑桿30相對套管10向上移動,如圖5及圖6所示,此時兩壓縮彈簧51、52即因抵靠部31向上移動而受到擠壓,而兩回復彈簧61、62即因故設於抵靠部31且因抵靠部31向上移動而受到拉扯,過程中兩滑套41、42兩滑套41、42的鋼珠432同時抵靠於滑桿30及套管10且作滾動移動;當本創作向上離開被測式按鍵時,滑桿30失去下方向上抵靠的力,且因抵靠部31受到兩壓縮彈簧51、52向下回推的力加上兩回復彈簧向下拉回的力,進而使整體恢復最初狀態。以上整個運動過程中,滑桿30與兩端套21、22及套管10並無直接接觸,而是以鋼珠432間接抵靠於套管10的內壁面且作滾動移動,所以不會產生摩擦消耗等問題,並且因兩回復彈簧61、62在運動過程中不會左右偏擺,而兩壓縮彈簧51、52的長度適中也能使左右偏擺的幅度減小,能避免彈簧與套管10的內壁面摩擦的問題。When the present invention is used, as shown in FIG. 9, the outer wall surface of the sleeve 10 is screwed to the fixing member A, and the fixing member A is coupled to the machine table B, whereby the creation can be moved up and down with the machine table B. When the present design is pressed against the button to be tested, due to the resilience of the tested button itself or the end of the stroke of the tested button itself, the pressing head 70 is driven by an upwardly abutting force to drive the slider 30 relative to each other. The sleeve 10 is moved upward, as shown in Figs. 5 and 6, at which time the two compression springs 51, 52 are squeezed by the upward movement of the abutting portion 31, and the two return springs 61, 62 are placed against each other for any reason. The portion 31 is pulled by the upward movement of the abutting portion 31. During the process, the steel balls 432 of the two sliding sleeves 41 and 42 of the sliding sleeves 41 and 42 simultaneously abut against the sliding rod 30 and the sleeve 10 and are moved by rolling; When the test button is moved upward, the slide bar 30 loses the downward abutting force, and the abutting portion 31 receives the force of the two compression springs 51, 52 pushing back downwards, and the force of the two return springs is pulled back. Restore the overall state to its original state. During the entire movement, the slide bar 30 is not in direct contact with the end sleeves 21, 22 and the sleeve 10, but is indirectly opposed to the inner wall surface of the sleeve 10 by the steel ball 432 and is moved by rolling, so that no friction occurs. Consumption and other problems, and because the two return springs 61, 62 do not yaw left and right during the movement, and the length of the two compression springs 51, 52 is moderate, the amplitude of the left and right yaw can be reduced, and the spring and the sleeve 10 can be avoided. The problem of friction on the inner wall surface.
