Detailed Description
The present invention will be described in further detail with reference to examples.
As shown in fig. 1-6: the utility model provides a prevent people's mistake bolt, includes bolt sleeve 3, bolt sleeve 3 is inside to be provided with bolt post 2, and bolt post 2 removes along bolt sleeve 3, be provided with manual operation pole 1 on bolt post 2, leave on bolt sleeve 3 and reserve hole 5, reserve hole 5 and be used for placing manual operation pole 1 when shutting, bolt post 2 removes the side and is provided with spring 6.
And a limiting device 4 for limiting the expansion and contraction of the spring 6 and the movement of the manual operating rod 1 is arranged in the latch sleeve 3.
The manual operating rod 1 is movably connected with the bolt column 2.
Manual operation pole 1 includes slender pole 9, slender pole 9 one end is protruding 7 of toper, and the other end is cylindrical protruding 8, the long limit of the protruding 7 of toper is the same with cylindrical protruding 8's diameter, be provided with on the manual operation pole 1 and remove slot hole 11, remove slot hole 11 one end and be provided with slot hole tip 10, it is the same with slender pole 9 part diameter to remove slot hole 11 width, and slot hole tip 10 is the same with cylindrical protruding 8 diameters.
The long hole end 10 has the same diameter as the opening 5.
The surface of the latch post 2 is provided with an opening 12, and the diameter of the opening 12 is the same as that of the thin rod 9.
The utility model discloses a theory of operation:
through bolt post 2 at the radial trompil of end, manual operation pole 1 passes the hole, prevents to drop through the protruding both ends of manual operation pole 1, and manual operation pole 1 can be along bolt post 2 radial movement (with the figure 1 condition, allow it to remove at the vertical direction) in bolt post trompil position, and the position that manual operation pole was located when bolt post 2 is in the shutting state reserves hole 5 to the bolt sleeve, reserve hole 5 diameter for the protruding diameter of 1 lower extreme of manual operation pole, allow manual operation pole 1 to take in the sleeve here and reserve hole 5, and manual operation pole 1 does not influence another door and closes this moment. In other positions, the manual operating lever 1 can only be in an extended state, and the other door cannot be closed. Especially in that the length and thickness of the manual lever 1 are sufficient to prevent the other door from being closed in the extended state of the manual lever 1. The manual operation rod 1 does not only move in the radial direction of the bolt column 2, but also needs to move along with the bolt column 2 in the axial direction of the bolt column 2, so that an axial long hole needs to be formed in the bolt sleeve 3, the axial long hole is opposite to a reserved hole 5 of the bolt sleeve, the width of the long hole is the diameter of a thin rod in the middle of the manual operation rod, the length of the long hole is from the middle position to the tail end of the bolt sleeve 3, and the width of the long hole in the opposite position of the bolt sleeve 5 is larger than the protruding diameter of the upper end of the. After the manual operating rod 1 is inserted into the pin sleeve preformed hole 5, the spring 6 is in a compressed state, and the elastic force acts on the manual operating rod 1 to keep the manual operating rod in the pin sleeve preformed hole 5 without popping.
When the latch post 2 is in the unlatched condition, the spring 6 holds it in the condition shown. The latch sleeve 3 is integrally mounted on the gate. The stop means 4 acts both as a stop for the manually operable lever 1 to indicate its retractable position and as a stop for the spring 6 and the bolt 2 to maintain its unlatched condition.
