Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, an embodiment of the present invention provides a lock, including a first housing 1, a second housing 2, a positioning element 3 and a positioning groove 4. The side of the first housing 1 facing the second housing 2 is provided with mounting holes 11. The rear end of the positioning member 3 is disposed in the mounting hole 11, the front end of the positioning member is disposed outside the first housing 1, and the front end of the positioning member 3 can extend and retract along the direction from the first housing 1 to the second housing 2. The positioning groove 4 is disposed on a side surface of the second housing 2 facing the first housing 1, and corresponds to a front end of the positioning member 3, so that the front end of the positioning member 3 can extend into or move out of the positioning groove 4.
The embodiment of the utility model provides a tool to lock, when closing the door of installing first casing 1, when the front end of setting element 3 is run into the lateral wall of installing second casing 2, along second casing 2 to the direction withdrawal of first casing 1, when the front end of setting element 3 moves the position department that positioning groove 4 corresponds along with the removal of door, the front end of setting element 3 stretches out along the direction of first casing 1 to second casing 2, and stretch into in positioning groove 4, in order to realize the alignment of first casing 1 and second casing 2, later spring bolt 5 stretches out first casing 1 of locking and second casing 2. Because the tool to lock of this application is provided with setting element 3 and positioning groove 4, earlier with first casing 1 and the accurate counterpoint of second casing 2 before 5 locks of spring bolt to can prevent the condition of 5 jamming of spring bolt, and then can realize locking fast.
Optionally, the lockset comprises a plurality of positioning parts 3 and a plurality of positioning grooves 4, so that the positioning force generated during positioning is larger, and the positioning effect is better. The periphery of the bolt moving hole on the first shell 1 surrounds a plurality of mounting holes 11 at intervals. The rear ends of the positioning members 3 are uniformly arranged in one mounting hole 11, and the front ends are arranged outside the first shell 1. One positioning groove 4 is uniformly formed on the second housing 2 at the corresponding position of the front ends of the plurality of positioning pieces 3. Thereby the positioning force that produces around the spring bolt activity hole during messenger's location is more even, and then prevents the spring bolt 5 jamming better.
As shown in fig. 1, the lock provided by the embodiment of the present invention includes two positioning elements 3 and two positioning grooves 4. Two mounting holes 11 are arranged at the opposite positions of the upper side and the lower side of the bolt moving hole on the first shell 1. Rear end homogeneous one of two setting elements 3 sets up in a mounting hole 11, and the front end all sets up in the outside of first casing 1, homogeneous one sets up a positioning groove 4 on the second casing 2 of the corresponding position department of the front end of two setting elements 3 to set up setting element 3 in the relative position department of upside and downside of spring bolt movable hole. In practice, the deformation of door, especially the deformation of the door of switch board, mainly the surface takes place to be crooked, and setting element 3 sets up in the upside of spring bolt activity hole and the relative position department of downside, and the local emergence of the door that can the certain degree prevention spring bolt activity hole position department is crooked to further be favorable to the accurate of first casing 1 and second casing 2 to counterpoint, and then can further prevent the condition of 5 jamming of spring bolt.
With continued reference to fig. 1, the positioning member 3 includes a positioning ball 31. The body 312 of the positioning collision bead 31 is disposed in the mounting hole 11, the bead 311 of the positioning collision bead 31 can extend and contract in the direction from the first casing 1 to the second casing 2, and the portion of the bead 311 exposed outside the body 312 is disposed outside the first casing 1. The shape of the positioning groove 4 matches the shape of the outer wall of the ball 311 disposed outside the first housing 1.
The positioning ball 31 is composed of a housing, a spring, and a ball 311, and the ball 311 can be pushed by the spring with a certain pressure to move along the axial direction of the housing. The positioning collision bead 31 is made of easily available materials, is low in cost and can reduce the cost of the whole lockset.
In practical applications, as shown in fig. 1 and 2, the body 312 of the positioning collision bead 31 includes a first cylinder 312a and a second cylinder 312b, and the mounting hole 11 includes a first ring groove 111 and a second ring groove 112. The outer diameter of the first cylinder 312a is larger than the outer diameter of the second cylinder 312 b. The external diameter of first annular groove 111 is greater than the external diameter of second annular groove 112, and second cylinder 312b sets up in second annular groove 112, first cylinder 312a sets up in first annular groove 111, thereby can make body 312 set up completely in first casing 1, and behind the installation location bumping ball 31, the terminal surface of body 312 towards second casing 2 is parallel and level with the side of first casing 1 towards second casing 2, this door is closing the back, and does not have the gap between the lateral wall, the degree of agreeing with is higher, and then can further prevent the jamming of spring bolt 5.
Optionally, the outer wall of the body 312 of the positioning collision bead 31 and the inner wall of the mounting hole 11 are in interference fit in the radial direction, that is, the outer diameter of the outer wall of the body 312 is slightly larger than the inner diameter of the inner wall of the mounting hole 11. When the body 312 includes the first cylinder 312a and the second cylinder 312b, and the mounting hole 11 includes the first ring groove 111 and the second ring groove 112, the outer diameter of the outer wall of the first cylinder 312a is slightly larger than the inner diameter of the inner wall of the first ring groove 111, and the outer diameter of the outer wall of the second cylinder 312b is slightly larger than the inner diameter of the inner wall of the second ring groove 112. Therefore, the body 312 of the positioning collision bead 31 is more tightly installed in the installation hole 11, and further, in the door closing process, the positioning collision bead 31 does not shake, and the positioning between the first casing 1 and the second casing 2 can be more accurate.
The utility model discloses another embodiment still provides a switch board, including foretell tool to lock. A first shell 1 of the lock is installed on a door of a power distribution cabinet, and a second shell 2 is installed on a side wall of the power distribution cabinet.
The embodiments in the present specification are described in a progressive manner, and the same or similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments.
The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure.
