Description

道路反光标记用反光片 技术领域 本发明涉及一种道路反光标记用反光片，特別与开模容易、模 具不易受损率、加工成本低且原设计的反光度得以充分运用的反光 片结构有关。 背景技术 现有技术中， 台湾第 90224744号专利揭示了一种道路反光标 记用反光片 94,其结构如图 1所示，主要是由片体 940和垫片 944 组成，在片体 940的整个内表面上形成反光棱，并在片体 940的整 个内表面上形成复数加强筋 941 ,垫片 944通过超声波； I：早接与片体 940结合， 令反光片 94不需电镀而仍具有发光功能， 并因加强筋 941与垫片 944浮接在一起， 而令片体 940上形成复数密闭空间， 使水份不会渗入, 保持较佳的反光效果， 即使某一处受撞破损， 也 因加强筋 941阻挡， 防止水继续浸入整个反光片 94, 令反光效果 受损小。  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retroreflective sheeting for road reflective marking, which is particularly related to a reflector structure in which mold opening is easy, mold is not easily damaged, processing cost is low, and the original design is fully utilized. BACKGROUND OF THE INVENTION In the prior art, Taiwan Patent No. 90224744 discloses a retroreflective sheeting 94 for road reflective marking, the structure of which is shown in Fig. 1, which is mainly composed of a sheet body 940 and a spacer 944, which is entirely in the whole body 940. A reflective rib is formed on the inner surface, and a plurality of reinforcing ribs 941 are formed on the entire inner surface of the sheet body 940, and the spacer 944 passes through the ultrasonic wave; I: early bonding with the sheet body 940, so that the reflective sheet 94 does not need to be plated and still has light. Function, and because the reinforcing rib 941 and the gasket 944 are floated together, the plurality of sealed spaces are formed on the sheet body 940, so that the water does not penetrate, and the reflection effect is better, even if the damage is damaged at a certain place, Because the rib 941 blocks, it prevents the water from continuing to immerse into the entire reflector 94, so that the reflection effect is less damaged.
但是， 此结构的反光片 94， 由于加强筋 941形成在片体 940 的反光棱上， 不«口大了片体 940的开模难度， 而且， 使片体 940 在加工生产中，模具受损率也高，一幅模具可加工件数大大减少（大 约只能加工三十万个）， 无形中增大了加工成本， 致使产品成本居 高不下，再则，此结构还导致片体 940在加工中的整体缩水率不同， 造成反光棱发生变形， 大大影响了反光度， 实际产品的反光度只具 有原设计的 30%左右， 因此， 台湾第 90224744号专利所揭示的反 光片 94结构亟待于改进。 发明内容 本发明的目的在于提供一种道路反光标记用反光片，其开模容 易，模具不易受损率， 加工成本低， 且原设计的反光度得以充分运 用。  However, the retroreflective sheeting 94 of this structure is formed on the reflecting edge of the sheet body 940 because the reinforcing rib 941 is not formed, and the mold opening of the sheet body 940 is not difficult, and the mold body 940 is damaged during processing. The rate is also high, the number of parts that can be processed in a mold is greatly reduced (about 300,000 pieces can be processed), which inevitably increases the processing cost, resulting in high product cost. Moreover, this structure also causes the sheet 940 to be processed. The overall shrinkage rate is different, causing deformation of the reflective ribs, which greatly affects the degree of glare. The actual product has only about 30% of the original design. Therefore, the structure of the reflector 94 disclosed in Taiwan Patent No. 90224744 needs to be improved. . Disclosure of the Invention An object of the present invention is to provide a retroreflective sheeting for road reflective marking, which is easy to mold open, has a low mold damage rate, has low processing cost, and is fully utilized in the original design.
为达成上述目的， 本发明的解决方案是：  To achieve the above object, the solution of the present invention is:
一种道路反光标记用反光片，在片体的整个内表面上形成反光 棱， 垫片通过超声波悍接与片体结合， 其中： 在垫片的内表面沿反 光棱的延伸方向增设复数纵向加强筋，且此纵向加强筋的顶缘形成 恰可与反光棱吻合的锯齿,纵向加强筋的锯齿通过超声波焊接与片 体的反光棱焊接在一起， 而令片体上形成复数密闭空间。 A reflective sheet for road reflective marking, forming a reflective rib on the entire inner surface of the sheet, and the spacer is combined with the sheet by ultrasonic splicing, wherein: a plurality of longitudinal reinforcements are added on the inner surface of the spacer along the extending direction of the reflective rib a rib, and the top edge of the longitudinal reinforcing rib forms a serration that coincides with the reflecting rib, and the serration of the longitudinal reinforcing rib is ultrasonically welded and pieced The reflective ribs of the body are welded together to form a plurality of confined spaces on the sheet.
所述垫片的内表面还增设横向加强筋，此横向加强筋与纵向加 强筋交叉，横向加强筋也通过超声波焊接与片体焊接在一起，进而 增加片体的强度。  The inner surface of the gasket is further provided with a transverse reinforcing rib, and the transverse reinforcing rib intersects with the longitudinal reinforcing rib, and the transverse reinforcing rib is also welded to the sheet by ultrasonic welding, thereby increasing the strength of the sheet.
所述垫片的外表面还形成复数个结合柱,此结合柱***填充料 中，可扩大反光片整体与填充料之间的接触面，提高填充料之间附 着力， 避免受震后， 反光片与填充料之间产生分离。  The outer surface of the gasket further forms a plurality of bonding columns, and the bonding column is inserted into the filler, which can enlarge the contact surface between the whole reflector and the filler, improve the adhesion between the fillers, and avoid reflection after the earthquake. Separation occurs between the sheet and the filler.
采用上述结构后，本发明由于将纵向加强筋和横向加强筋都形 成在垫片上， 而未形成在片体的反光棱上，使只具有反光棱的片体 开模难度大大降仳，而具有纵向加强筋和横向加强筋的垫片开模难 度与现有的垫片相比变化甚小，而且，只具有反光棱的片体在加工 生产中，模具受损率低，一幅模具可加工件数大大增加（大约能加 工近百万个）， 加工成本大大降低， 再则， 只具有反光棱的片体在 加工中的整体缩水率保持一致，反光棱不会发生变形，保持了极佳 的反光效果， 使原设计的反光度得以充分运用。 附图说明 图 1是习用品的立体分解图；  After adopting the above structure, the present invention is formed on the spacer by the longitudinal reinforcing ribs and the lateral reinforcing ribs, and is not formed on the reflecting edge of the sheet body, so that the opening of the sheet having only the reflecting edge is greatly reduced, and The difficulty of opening the gasket with the longitudinal reinforcing ribs and the transverse reinforcing ribs is very small compared with the existing gaskets. Moreover, the sheet with only the reflective ribs has a low mold damage rate in the processing and production, and one mold can be used. The number of workpieces is greatly increased (approximately one million can be processed), the processing cost is greatly reduced, and the sheet with only the reflective ribs has the same overall shrinkage during processing, and the reflective ribs are not deformed, which is excellent. The reflective effect makes the original design's illuminance fully utilized. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a conventional article;
