Locking device with wedge surface for trench cover plate
The invention discloses a locking device with a wedge surface for a trench cover plate. The locking device with the wedge surface for the trench cover plate comprises an outer frame arranged in a notch and the cover plate matched with the outer frame, wherein one end of the cover plate is connected with one side of the outer frame through a hinge to form a turnover structure; the locking device isarranged between the other end of the cover plate and the outer frame; the locking device comprises a telescopic mechanism and a spring bolt arranged at the end of the telescopic mechanism; the top surface of the spring bolt comprises a horizontal part and an inclined part at the front end of the horizontal part, and a wedge surface with a certain inclination is formed; a first lock hole is formed in the end face of the end, provided with the locking device, of the cover plate; a second lock hole is formed in the side face, corresponding to the first lock hole, of the outer frame; the springbolt penetrates through the first lock hole and then stretches into the second lock hole; and the wedge face of the top face of the spring bolt abuts against the upper edge of the second lock hole. The locking device is reasonable in structure, tight in locking, easy and convenient to machine and manufacture, and easy and convenient to operate.
本发明公开了一种沟盖板用带楔面的锁定装置，包括设置在槽口内的外框及与外框相匹配的盖板，所述盖板一端通过铰链与外框的一侧连接，形成可翻转结构；所述盖板另一端与外框之间设置锁定装置；所述锁定装置包括伸缩机构及设置在伸缩机构端部的锁舌；所述锁舌的顶面包括水平部及水平部前端的倾斜部，形成有一定斜度的楔面；所述盖板设置锁定装置的一端端面上开设第一锁孔；所述外框上与第一锁孔相对应的侧面开设第二锁孔，所述锁舌穿过第一锁孔后伸至第二锁孔内，锁舌顶面的楔面抵住第二锁孔的上边缘，本锁定装置结构合理、锁定紧密、加工制造简便，操作简单方便。
