After the lock is installed and positioned, the positioning surface on the wrench handle is in close contact with the outer wall of the cover plate. Turning the wrench handle switches the positioning surface to drive the pull rod, and the reed moves forward and backward under the action of the spring, so that the deadbolt reaches the closed or open state .

As a further improvement of the utility model, three positioning surfaces are provided on the connecting end of the wrench handle and the pull rod, which can be selected and adjusted according to the thickness of the connecting profile wall, thereby enhancing the practicability of the lock.

As a further improvement of the utility model, the distance from the eccentric hole to the above three positioning surfaces increases or decreases sequentially along the rotation direction of the wrench handle, thereby reducing or avoiding operational errors during installation.

As a further improvement of the utility model, the spring is in a compressed state in the closed state of the deadbolt, which increases the tension of the spring during the process of the lock from the lock to release, and improves the sensitivity of the lock.

As a further improvement of the utility model, the positioning surfaces on the wrench handle are connected by arc surfaces, which is convenient for operation.

As a further improvement of the utility model, the cover plate is also provided with screw holes for fixing the lock itself, which facilitates the installation of the lock.

The utility model changes the installation and design idea of the combination of reed and eccentric wheel in the original lockset, leads the eccentric design idea to the outside of the lock case, introduces the eccentric wrench handle, and arranges the position of the positioning pin skillfully. To achieve the effect of opening and closing, the utility model reduces the main parts such as the eccentric wheel required by the original lock, and at the same time does not need to consider the highly complex matching relationship in the original lock, which simplifies and speeds up the manufacturing and reduces the production cost. , and the installation is more intuitive, convenient and fast, which improves work efficiency.

Detailed ways

The following structural drawings and embodiments clearly and completely describe the technical solution in the utility model.

Embodiment 1, the utility model relates to a reed lock, as shown in Figure 3: used to build the connection between parallel profiles in a commodity fair or store structure assembly system, as shown in Figure 1 and Figure 2: the lock includes Lock case 2, reed 1, wrench handle 9, spring 4 and pull rod 3 are five main components. The lock case 2 is provided with an end cover 8, and the lock case 2 can be cast into one-time molding or assembled through profiles. 2 is a hollow structure, with through holes formed in the front and back; the end cover 8 is fixed on the rear end surface of the lock case 2, and a central hole is provided in the center of the end cover 8 for the pull rod 3 to pass through; the reed 1 is bent to form a double layer As for the clamping wall 12, the front end of the double-layer clamping wall 12 is bent to form three locking tongues 11, and when no external force is applied, the three locking tongues 11 form a row when loosened.

As shown in Figure 2, the reed 1 is installed in the lock case 2, and its deadbolt 11 passes through the lock case 2 so as to be connected with the profile 6 in the assembly system; The rear end of the piece 1 forms an axial positioning connection, and the other end of the pull rod 3 is inserted into the eccentric hole 91 provided with the wrench handle 9 through the connecting pin 10; the spring 1 is located in the lock case 2 and is sleeved on the pull rod 3, and its The two ends act on the rear end of the reed 1 and the inner wall of the end cover 8 respectively; the positioning pin 5 is clamped between the double-layer clamping walls 12 and is located at the place where the double-layer clamping walls 12 are bent to form a lock tongue, and its upper and lower ends are respectively connected with The lock housing 2 is fixedly connected;
