As shown in fig. 1, an embodiment of the present utility model provides a locking mechanism applied to an apparatus housing, the apparatus housing including a casing 1 having one end opened, and a rotary cover 2 rotatably provided on the casing 1 for closing the opened end of the casing 1, characterized in that the locking mechanism includes:
the lock catch 4 is correspondingly arranged on the rotary cover 2, and the lock catch 4 is provided with a plurality of lock grooves which are in matched connection with the lock rod 3;
when the lock rod 3 moves to a first position in a direction away from the casing 1, the rotary cover 2 can rotate relative to the casing 1, so that the lock rod 3 can extend into or separate from the first locking groove 5; when the lock lever 3 is moved from the first position to the second position in a direction approaching the casing 1, the lock lever 3 slides into the second locking groove 6, and the rotary cover 2 is fixed to the casing 1.
For example, a locking mechanism is applied to the apparatus case for locking the rotary cover 2 in the apparatus case to the housing 1 of the apparatus case or unlocking the rotary cover 2 so as to be rotatable with respect to the housing 1. As shown in fig. 2, the locking mechanism includes a lock lever 3 that is provided on the housing 1 and is movable relative to the housing 1 in a direction approaching and moving away from the housing 1 within a predetermined range, that is, the lock lever 3 is not separated from the housing 1 and is movable relative to the housing 1. The rotary cover 2 is provided with a lock catch 4, and the lock catch 4 comprises a plurality of lock grooves which can be matched and connected with the lock rod 3, such as a first lock groove 5 and a second lock groove 6. When the lock lever 3 moves to the first position in a direction away from the casing 1, that is, moves to the first position outside the casing 1, the lock lever 3 is located in the first locking groove 5 and can be separated from the first locking groove 5, at this time, the rotating cover 2 can rotate relative to the casing 1, that is, the rotating cover 2 can rotate relative to the casing 1, so that the lock lever 3 extends into the first locking groove 5 or is separated from the first locking groove 5, and the extending and separating of the first locking groove 5 are realized based on the rotation of the rotating cover 2. When the lock lever 3 moves from the first position to the second position in a direction approaching the casing 1, that is, moves to the second position in a direction inside the casing 1, the lock lever 3 slides into the second locking groove 6, and the rotary cover 2 is fixed to the casing 1. That is, the rotary cover 2 cannot be separated from the casing 1 when the lock lever 3 is located at the second position, and the lock lever 3 cannot be separated from the second locking groove 6 due to the rotation of the rotary cover 2.
Based on the disclosure of the above embodiment, it can be known that the beneficial effects that this embodiment possesses include that locking mechanism overall structure is simple, easily prepares, set up locking lever 3 on the casing 1 of non-movable, set up hasp 4 on movable rotation lid 2 in this application, and spacing on casing 1 with locking lever 3, allow locking lever 3 to remove in a predetermined range simultaneously, and hasp 4 contains different locked grooves, so can make locking lever 3 be located even not break away from casing 1 when first locked groove 5, also can allow rotation lid 2 to rotate relative casing 1, and when the lid 2 is rotated in casing 1 to the locking, only need make locking lever 3 be located second locked groove 6 can, easy operation is convenient.
Further, a fixing bracket 7 including a connecting hole is provided on the casing 1 in this embodiment, the lock rod 3 includes a screw rod and a screw cap, the screw rod is threaded on the connecting hole, the middle section of the screw rod is unthreaded, when the lock rod 3 moves to the first position, the middle section of the screw rod moves into the connecting hole, and the screw cap is located outside the second locking groove 6. In practice, the locking bar 3 may be formed by a safety screw. The lock rod 3 in the embodiment has the performance of a safety screw, and the thread is not arranged at the middle section of the lock rod, so that the lock rod 3 can be effectively prevented from being easily withdrawn when the lock rod 3 is detached, and the lock rod 3 is separated from the shell 1.
Further, as shown in fig. 3 and 4, a fastening component is disposed on a threaded section of the screw in the present embodiment, which is located on the side of the fixing bracket 7 facing the inside of the casing 1. The lock lever 3 can be integrally fastened to the casing 1 based on the provision of the fastening member on the tail section of the screw, and the rotary cover 2 can be locked to the casing 1, while the screw can be prevented from falling off.
Optionally, the fastening assembly comprises a backstop washer 9 and a nut 8 located between the backstop washer 9 and the fixed bracket 7. The nut 8 may be an embedded nut 8, or other types of nuts 8, particularly without limitation.
With continued reference to fig. 2, the first locking groove 5 is located in the second locking groove 6, that is, the width of the first locking groove 5 is smaller than that of the second locking groove 6, in this embodiment, the width of the first locking groove 5 is equivalent to the diameter of the screw rod, and the width of the second locking groove 6 is equivalent to the diameter of the screw cap. In addition, the first locking groove 5 and the second locking groove 6 can both pass through the screw rod along the direction perpendicular to the screw rod, that is, in the process of rotating the rotating cover 2, the first locking groove 5 and the second locking groove 6 can both pass through the screw rod, and can also be separated from the screw rod.
Specifically, the first locking groove 5 in this embodiment is a U-shaped groove formed on the rotary cover 2, and a notch of the U-shaped groove penetrates through a side edge of the rotary cover 2 facing the lock lever 3, so that the screw rod can smoothly slide into the U-shaped groove.
The second locking groove 6 is a counter bore formed on the outer side wall of the rotary cover 2, and the appearance of the counter bore is the same as that of the screw cap (the specific shape is not limited, and the shape is circular, rectangular and the like) so as to be used for forming a limiting cavity of the limiting screw cap, the depth of the limiting cavity can be flush with the height of the screw cap, and can be slightly smaller or slightly larger than the height of the screw cap, but the cavity wall of the limiting cavity must have a projection overlapping area with the side wall of the screw cap. When the screw cap slides into the limiting cavity, the lock rod 3 is in the second position, and the screw cap is blocked by the limiting cavity and cannot move along the direction perpendicular to the screw, so that the rotating cover 2 is locked on the casing 1 and cannot rotate.
Further, the U-shaped groove in this embodiment is formed on the bottom wall of the counter bore, and at least a portion of the counter bore corresponding to the notch of the U-shaped groove penetrates through the side edge of the rotary cover 2 facing the lock rod 3, and taking a screw cap as an example, the outline of the counter bore corresponds to an inverted C-shape. Of course, the area of the counter bore penetrating through the side edge of the rotary cover 2 can be larger than the notch of the U-shaped groove, but the width is smaller than the width of the screw cap, so that the screw cap can be prevented from being separated from the limiting cavity along with the rotation of the rotary cover 2, and locking failure is caused.
When the user wants to unlock the rotary cover 2, the user only needs to move the lock rod 3 to the first position along the outer side of the casing 1 in the length direction of the screw rod, so that the screw cap is separated from the limiting cavity, namely the second locking groove 6, and the operation is simple and convenient, and the lock rod 3 cannot be lost.
Another embodiment of the utility model also provides an apparatus housing comprising a locking mechanism as described in any of the embodiments above.
The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
