DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0023] The utility model provides Figures 1 to 4 A novel anti-theft manhole cover lock shown in the figure comprises a lock cover 1, the lock cover 1 is in a square structure, two bolt holes 2 are provided on the inner wall at the bottom of the lock cover 1, mounting bolts 3 are threadedly connected in the two bolt holes 2, a positioning hole 4 is provided on the inner wall at the bottom of the lock cover 1, a plurality of positioning holes 4 are provided, and the plurality of positioning holes 4 are distributed in a square structure, a movable opening 5 is provided on the lock cover 1, an anti-theft lock 6 is movably provided in the movable opening 5, a stopper 7 is fixedly connected to the top of the anti-theft lock 6, a connecting block 8 is fixedly connected to the bottom end of the anti-theft lock 6, sockets 9 are provided on both sides of the inner wall of the connecting block 8, a bayonet 10 is provided on the connecting block 8, and a connecting A lock tongue 11 is movably provided in the block 8, and a round block 12 is hinged on the lock tongue 11. The lock tongue 11 is engaged with the bayonet 10. The installation bolt 3 is used to facilitate the installation and use of the equipment, and multiple positioning holes 4 are used to cooperate with the external positioning structure to improve the accuracy of equipment installation. In addition, the external positioning structure is a prior art, such as a positioning rod, etc., which will not be described in detail in this article. At the same time, through the lock cover 1, the lock tongue 11, and the anti-theft lock 6, the anti-theft lock 6 structure can be utilized, which is beneficial to improve the anti-theft performance, stable and reliable use, strong applicability and good practicality, and at the same time, it is convenient for the positioning and installation operation of the equipment, which is convenient and quick.
[0024] Furthermore, two spring telescopic rods 13 are arranged on the lock tongue 11, and the two spring telescopic rods 13 are arranged front and back. The telescopic ends of the two spring telescopic rods 13 are fixedly connected with semicircular movable blocks 14, and the two semicircular movable blocks 14 are plugged into the corresponding sockets 9.
