[0021] As shown in Figure 1 A transmission lock box with an anti-misoperation function, comprising a lock box body 3, a transmission gear 1 arranged in the lock box body 3, a transmission rod 2 arranged through the lock box body 3, the transmission rod 2 sliding left and right through the rotation of the transmission gear 1, an anti-misoperation mechanism 4 arranged between the lock box body 3 and the transmission rod 2, the transmission rod 2 sliding locked through the closed anti-misoperation mechanism 4, and the anti-misoperation mechanism 4 being normally open through the window frame profile in the window closed state.
[0022] In actual use, an anti-misoperation mechanism 4 is added between the lock box body 3 and the transmission rod 2 of the existing transmission lock box, the anti-misoperation mechanism 4 being in a locked closed state in a normal state, in which state the transmission rod 2 cannot slide left and right, and only when the anti-misoperation mechanism 4 is opened can the transmission rod 2 slide left and right. The anti-misoperation mechanism 4 is triggered to form a normally open state through the window frame profile in the window closed state, so that when the window is closed, the anti-misoperation mechanism 4 is opened, and the handle can drive the hardware in the window profile to move, thereby realizing multiple opening modes of the window. When the window is opened, the handle cannot be turned because the anti-misoperation mechanism 4 is closed, so that the window has only one opening mode.
[0023] As shown in Figure 2 Further improved, the anti-misoperation mechanism 4 comprises a sliding groove 42 arranged on the lock box body 3, an anti-misoperation cover 41 slidingly arranged in the sliding groove 42, and a clamping groove 44 arranged on the transmission rod 2, a reset mechanism 43 being further arranged between the anti-misoperation cover 41 and the lock box body 3, and the transmission rod 2 being slidingly limited and locked after being inserted into the clamping groove 44 through the anti-misoperation cover 41.
[0024] The anti-misoperation cover 41 is slidably connected in the sliding groove 42 on the lock box body 3, and is locked by being inserted into the clamping groove 44 after sliding through the reset mechanism 43 to the transmission rod 2, so as to avoid that the transmission rod 2 is slid by rotating the handle, and when the window sash is closed, the anti-misoperation cover 41 is stopped by contacting the window frame profile, so that the anti-misoperation cover 41 is in the open state when the window is closed, and the transmission rod 2 can be slid left and right at will by rotating the handle, and the anti-misoperation cover 41 is automatically locked again by the reset mechanism 43 during the opening of the window, so that the position of the anti-misoperation cover 41 and the clamping groove 44 is naturally switched, and the transmission lock box naturally has the anti-misoperation function, which is simple and convenient in operation and does not need manual anti-misoperation operation.
[0025] Further improvement is that the sliding groove 42 is arranged at the bottom of the lock box body 3, and the outer side of the anti-misoperation cover 41 is provided with the outward protruding stop block 5.
[0026] The sliding groove 42 is arranged at the bottom of the lock box body 3, so that the outer side of the anti-misoperation cover 41 is closer to the window frame profile after installation, and the outward protruding stop block 5 is further formed on the outer side of the anti-misoperation cover 41, so that the protruding length of the stop block 5 is smaller and the concealment is better, and the anti-misoperation cover 41 can be effectively stopped by contacting the window frame profile during the closing of the window sash, and the structure is simpler.
[0027] Further improvement is that, as shown in the drawings, the inner side of the anti-misoperation cover 41 is provided with the upward protruding clamping block 7, and the bottom of the transmission rod 2 is recessed inward to form the clamping groove 44. Figure 3
[0028] When the transmission rod 2 is controlled by the anti-misoperation cover 41, the anti-misoperation cover 41 is arranged at the bottom of the lock box body 3 through the sliding groove 42, in order to better control the transmission rod 2, the clamping block 7 protruding towards the transmission rod 2 is formed on the inner side of the anti-misoperation cover 41, the anti-misoperation cover 41 is locked by cooperating with the clamping groove 44 through the clamping block 7, the overall thickness of the anti-misoperation cover 41 is smaller, and the anti-misoperation function is realized by the concave-convex structure, so that stable cooperation is realized without changing the overall size of the transmission lock box.
[0029] Further improvement is that the bottom of the transmission rod 2 is further provided with the inward recessed limiting groove 6, the clamping groove 44 is communicated with the limiting groove 6, and one end of the anti-misoperation cover 41 is located in the limiting groove 6.
[0030] Through the structure that the clamping groove 44 is communicated with the limiting groove 6, the installation and movement space of the anti-misoperation cover 41 is larger, when the anti-misoperation mechanism 4 is always opened through the window frame profile, the left and right sliding of the transmission rod 2 can also be limited through the two sides of the limiting groove 6, so that the problem that the sliding limit position of the transmission rod 2 cannot be controlled is solved, and the problem that the transmission rod 2 is inconvenient to slide after the anti-misoperation cover 41 is added is also solved.
[0031] Further improvement is that one side of the limiting groove 6 is provided with three clamping grooves 44, and the three clamping grooves 44 are respectively located in the middle and the two sides.
[0032] Through the cooperation of the three clamping grooves 44 and the anti-misoperation cover 41, after the rotation handle drives the hardware in the window profile to move and then opens in different ways, locking can be realized, so that the purpose that the handle cannot be turned when the window is opened in the way of flat opening, inward opening or outward opening is achieved.
[0033] Further improvement is that the reset mechanism 43 includes a mounting groove 431 arranged between the lock box body 3 and the anti-misoperation cover 41, and a spring 432 arranged in the mounting groove 431.
[0034] The spring 432 is embeddedly installed in the mounting groove 431 between the lock box body 3 and the anti-misoperation cover 41, and the mounting groove 431 can play a limiting role, avoiding the misalignment problem of the spring 432 in the stretching and retracting process, and through the reset of the spring 432, the cost is lower and the reset is faster.
[0035] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection required by the present application.
