Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
As shown in fig. 1, switching-over push-and-pull lock body includes casing 1, one side of casing 1 is connected with lock tongue board 2, the lock tongue hole has been seted up on the lock tongue board 2, spring bolt 3 is located in casing 1, and can stretch out or retract the spring bolt downthehole, be equipped with the square core hole on the casing 1 of this lock body, this lock body need not to connect promptly and can the pivoted handle, the door of supporting this lock body only needs the installation one handle that can exert the impetus, through pulling this handle, and then this spring bolt 3 with switching-over push-and-pull function takes place to rotate, through the hasp box contact in the inclined plane on its spring bolt 3 and the door frame, thereby in the 3 retraction casings of spring bolt. The door opening mode of the reversing push-pull lock body is simple and convenient, and the door opening mode that the lock tongue is pulled back into the lock body through the handle in the existing lock body is simplified.
As shown in fig. 2, a reset mechanism 4 is disposed in the housing 1, the reset mechanism 4 is connected to the rear end of the latch bolt 3, the reset mechanism 4 functions to force the latch bolt 3 to extend out of the latch bolt hole all the time, and the reset mechanism 4 can also function to block the rotation of the latch bolt 3, that is, the latch bolt 3 needs to overcome the force applied to the reset mechanism 4 to open the door, wherein the structure of the reset mechanism 4 may refer to the reset mechanism of ZL 201910839740.7, but not limited thereto, and the reset mechanism 4 may also adopt other embodiments.
The inside of the shell 1 is provided with a reverse locking piece 5, the reverse locking piece 5 is a simplification of a reverse locking mechanism, the reverse locking mechanism is an integral part, one end of the reverse locking piece is rotatably arranged on the shell 1, the other end of the reverse locking piece is connected with the shell 1 through a torsion spring 6, and the torsion spring 6 enables the reverse locking piece 5 to be switched between two states and further keeps the existing state of the reverse locking piece. One side of the anti-locking piece 5 is formed with a groove 51, this groove 51 matches with the shifting block of the lock core 7 that can insert in the lock body, when rotating the shifting block, it is through propping in the groove 51 of the anti-locking piece 5, make the anti-locking piece 5 rotate and overcome the power of torsional spring 6 and then change the state, wherein be located the first fender portion 52 of anti-locking piece 5 one side when being close to canceling release mechanical system 4, it keeps off at the rear of canceling release mechanical system 4, thereby make canceling release mechanical system 4 can't be back, this kind has realized the mesh that the spring bolt 3 can't retract in the spring bolt hole promptly, as shown in fig. 4, its anti-locking piece 5 is for having got into the locking state under the effect of lock core shifting block.
Further, as shown in fig. 3, a limiting vertical plate 53 is further formed on the back-locking piece 5, the front end of the limiting vertical plate 53 is also formed with two second stopping portions 531 at one side close to the torsion spring 6, the two second stopping portions are in the form of two notch steps, and are opposite to each other, the locking post 32 is formed at the tail end of the lock tongue 3, the second stopping portions 531 further strengthen the back-locking function of the lock body, the first stopping portions 52 are abutted to the tail end of the reset mechanism 4, the reset mechanism 4 cannot be retracted, the second stopping portions 531 are abutted to the locking post 32, the rotation of the lock tongue 3 can be limited, and the rotation of the lock tongue 3 is avoided even if the lock tongue 3 cannot be retracted. Particularly, when the tongue 3 is in contact with the keeper in a state of being inclined, it is liable to be forcibly pushed back into the tongue hole by a large force, and the counter lock 5 is liable to be damaged.
Further, the second stoppers 531 are disposed on upper and lower sides of the vertical position-limiting plate 53.
As shown in fig. 2 and 4, a reset mechanism 4 adopts a preferable mode, a reset push rod 41 is arranged in the housing 1, a receiving groove 42 is formed at the front end of the reset push rod 41, a first spring 43 is arranged in the receiving groove 42, a steel ball 44 is arranged at the front end of the first spring 43, hinge arms 411 are formed at two ends of the receiving groove 42, a hinge groove 31 matched with the hinge arms 411 is formed on the latch bolt 3, the latch bolt 3 is connected with the hinge arms 411 of the reset push rod 41 through the hinge groove 31, the tail end of the latch bolt 3 abuts against the steel ball 44, a second spring 45 is arranged at the rear end of the reset push rod 41, and the reset push rod 41 has a tendency of pushing the latch bolt 3 out to one side of the latch bolt hole due to the second spring 45. The storage tank 42 of this structure is located the rear end of spring bolt 3, therefore, its first spring 43 and steel ball 44 all are located the outer end of spring bolt 3, both compare in prior art with its structure of placing in the inside of spring bolt 3, more convenient to detach and change, consequently, the power that first spring 43 applyed on steel ball 44 is also adjusted more easily, can adjust this power according to the demand of using, let spring bolt 3 can adapt to external force and apply the power on the door, avoid blowing on the door when great wind, the upset has also taken place for spring bolt 3, lead to opening of door.
Further, the second spring 45 is preferably a conical coil spring, and when the conical coil spring is a linear spring, the conical coil spring is more stable and is less likely to cause a deviation in the direction of the acting force.
Further, a guide groove 11 is formed on the housing 1, and guide blocks 412 which are matched with the guide groove 11 are formed on the upper and lower sides of the reset push rod 41. The cooperation of the guide block 412 and the guide groove 11 ensures the moving direction of the reset push rod 41.
Furthermore, a limiting convex column 33 is formed on two sides of the lock tongue 3, and the limiting convex column 33 abuts against the lock tongue plate 2. The limit convex column 33 prevents the lock tongue 3 from separating from the lock tongue hole.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
