FIELD OF THE INVENTION The present invention relates to a keycap structure, and more particularly, to a keycap structure having an assembly foolproof function. / 、 Prior art: Generally speaking, the application of multiple keys (for example, blank key, etc.) on the keyboard §, k times, because the keycap length of the multiple key is longer than the keycap of ordinary keys, and the multiple key Most of the keycaps are made by plastic injection. ^ 幵 ~ Therefore, the overall strength (rigidity) will be weaker than that of general keycaps (rigidity is weaker, so the keycaps for multiple keys are prone to bending deformation.) For the above reasons, an extra $ 1 stiffener is usually added to the bottom of the keycap of the multiple key to reinforce its insufficient structural strength. As shown in the figure 丨, a balance bar can be set on the bottom of the keypad of the multiple key 1 1. A reinforcing rod 12 and a plurality of positioning engaging portions 13. The positioning engaging portion 13 is on the bottom of the seven-key keycap 1, and the balance rod 丨 丨 and the reinforcing rod 12 are engaged by positioning. The engaging portion 1.3 is fixed on the bottom of the multiple-key keycap 1. It is worth noting that the setting position of the reinforcing rod 12 is usually corresponding to-an elastic body (dome, connected to the bottom of the multiple-key keycap 1). (Not shown), and the notch portion of the reinforcing rod 12 It is toward the balance bar. In this way, the overall strength (rigidity) of the multiple keycap 1 can be enhanced. However, as shown in Figure 2, due to the operator's negligence during assembly, assembly errors occur, making The notched parts of the balance bar 丨 丨 and the reinforcement bar 丨 2 are all facing the same direction, so it is impossible to achieve the purpose of strengthening the multiplier keycaps, the overall strong production, and the door j 11). In other words, in the multiple-key keycap

Degree will be poor. In view of the keycap structure of this function, a keycap structure with assembling protection against the present invention is provided; At the same time, the Ba's muzzle functions as a sense of break. SUMMARY OF THE INVENTION The present invention basically employs the problems described below. That is, the surface of the present invention and the plurality of positioning engaging portions are on the assembly surface; and a reinforcing portion is provided on the assembly surface to reinforce the body, and the reinforcing body has an assembly surface abutting. In order to solve the problem, a keycap is included in the assembly table, and the assembly parts are formed as strong elements, and the reinforcing elements have a first bending radius through the positioning cards. And, at the same time, according to the keycap structure of the present invention, the reinforcing element further includes a first connection portion and a second connection portion, and the first connection portion and the second connection portion are respectively connected to the reinforcement. The body, and the length of the first connecting portion is smaller than the length of the second connecting portion. In the present invention, the keycap further includes a resisting element formed on the assembly surface, and the resisting element abuts the first connection portion. Also in the present invention, the reinforcing body has a substantially door-like shape. Also in the present invention, the keycap has a second bending arc received by the abutment of the reinforcing body. In the present invention, the reinforcing body, the first connection portion, and the first

In order to make the above-mentioned objects, features, and advantages of the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. "Thanks" Implementation Modes The preferred embodiments of the present invention will be described with reference to the drawings. Please refer to FIG. 3, the keycap structure 100 in this embodiment, the main keycap 110, a balance bar] 20 and a reinforcing element. The 112 keycap 2 has an assembly surface ⑴, a plurality of positioning engaging portions 2, two f ::: =, and-resisting elements ⑴, and a plurality of positioning Γ abutting parts 114 are also balance rods 120 formed on the assembly surface ⑴ It is set in detail on the keycap 11o. Specifically, the balance lever 12o is placed on the assembly surface m by using,, and above. ：: = f is set in the pivot seat ⑴ It is still possible to pivot the seat 113 as a fulcrum of rotation (not shown in the figure, the balance bar 120 111) makes relative rotation in the β direction. ”, ≫, ♦ cap 丨 10 (or the assembly surface is shown in FIG. 3 and FIG. 5, 1 is changed to a k part 112 and set to the keycap 11 〇 / ^ = 30 is through a positioning card The joint element m is composed of a reinforced body m and a reinforced body connected on the same day, and reinforced with two connecting portions 133. The reinforced body 131 and J are connected, 132 > and one and one are substantially door-shaped shapes ,: There is a first curved arc that abuts on the surface 11 1. The first joint, η mouth guard 'reinforced body 131 is connected to the assembly-connection joint 132 and the second connection 133, respectively.

In particular,; = ;: the connecting portion 132 is longer than the second connecting portion 133 "; and the portion 132 ... is a small second connecting first-connecting portion 132. Outer clothing: the middle of the two Γ: the abutment 114 is abutted-^ ^ ^ 1 〇〇 In this embodiment, the reinforcing body 1 31, the 妾 邛 1 32 and the second connecting portion j 33 are integrally formed. of.杷-: i: Jinshuo 'When assembling the keycap structure 100, the balance bar 120 = the pivot joint seat on the assembly surface lu of the keycap 110 can be firstly set in 13 and then, = the reinforcing element 130 is set The positioning and engaging portion 112 on the assembly surface 111 is strong: At the moment, due to the existence of the resisting element 114, the limb 131 of the reinforcing element 13 will be located on one side of the assembly surface, that is, the strengthening element 30 The notched portion (the gap between the first connection portion 132 and the second connection portion 133) must face the closed portion of the balance bar 120, otherwise the reinforcing element 13 cannot be installed on the assembly surface 111. At the same time, because the reinforcing element 13 (the reinforcing body 131) has a first bending arc, and the lengths of the first connecting portion 132 and the second connecting portion 丨 33 are different, that is, the length of the first connecting portion 丨 32 is smaller than苐 The length of the first connecting portion 133, plus the distribution position of the positioning and engaging portion η? And the resisting element 1 1 4 is limited, so the first connecting portion 1 3 2 of the reinforcing element 3 3 will resist the resisting element 11 4 In this way, the right and left directions of the reinforcing element 1 30 during assembly can be prevented from being mistaken, and the first bending curvature of the reinforcing element 丨 3 〇 (reinforcing body 131) cannot be matched with the key cap 丨 丨 〇. In particular, as shown in FIG. 4, when the reinforcing element 1 3 0 (reinforcing body 1 3 1) having the first bending arc is set on the assembly surface 11 1 of the keycap 11 〇, the 'keycap 11 0 will Because of the abutment of the reinforcing element 1 3 0 (reinforcing body 1 31), it has a second bending arc. As mentioned above, the keycap 丨 丨 〇 has a second bend
