Technical Field
[0001] The utility model belongs to the technical field of personal care appliances, and in particular relates to an elastic lock for an electric shaver. Background Art
[0002] As a tool for daily shaving for adult men, electric shavers have basically replaced traditional manual shavers. Existing electric shavers are divided into two types: integrated and detachable. The detachable electric shaver can disassemble the shaver head for cleaning and is widely used. The detachable shaver is fastened by an elastic lock. The existing elastic lock includes a connecting seat installed on the shaver body, a lock core installed on the shaver head, and an elastic lock installed on the connecting seat for controlling fastening. The elastic lock is two spring pieces, and a pin groove is provided on the connecting seat. The two spring pieces are respectively inserted into the pin groove for fixing, and then the lock core is inserted into the connecting seat for fastening. However, the assembly of this two-spring piece structure is more troublesome. Summary of the invention
[0003] The utility model aims to provide an elastic lock for a razor with a push-type elastic lock to solve the problems existing in the prior art. To achieve the above purpose, the specific technical scheme of the utility model is as follows: the elastic lock comprises a connecting seat, a push-type elastic lock for controlling tightening is installed on the connecting seat, a pluggable lock core is installed on the connecting seat, the connecting seat is mounted on the razor body, the lock core is mounted on the razor head, the razor head is connected to the razor body, the lock core is inserted into the connecting seat, and the lock core and the elastic lock are matched and tightened.
[0004] Furthermore, the connecting seat is provided with a receiving opening, locking openings are opened on both sides of the receiving opening, a positioning groove is provided on the receiving opening, and a protrusion is provided on the positioning groove.
[0005] Furthermore, the elastic lock is provided with a matching opening that matches the shape of the positioning groove, the matching opening is provided with a pin opening, the matching opening is provided with force arms extending outward on both sides, the force arms are provided with fastening arms extending inward, the fastening arms are provided with inward spring sheets, the spring sheets include elastic arms, the elastic arms are provided with contact surfaces, the distance between the fastening arms on both sides is smaller than the diameter of the receiving opening, so that the spring sheets can completely enter the lock opening, and the elastic lock is an integrated structure.
[0006] Furthermore, the lock core is provided with a lock groove that can cooperate with the spring piece and allow the spring piece to be embedded, and the lock core is also provided with a positioning rib that cooperates with the positioning groove to allow the spring piece to be embedded in the lock groove.
[0007] Furthermore, the mating mouth of the elastic lock is aligned with the positioning groove, and the elastic lock is pushed forward to allow the fastening arm to contact the receiving mouth. During this period, the spring sheet contacts the receiving mouth, and then pushed forward again. The spring sheet supports the fastening arm outward, and the force arm provides elastic support. When the spring sheet completely enters the lock mouth, the force arm resets the fastening arm so that the fastening arm fits tightly with the receiving mouth. At this time, the protrusion on the positioning groove is inserted into the pin mouth, which limits the position of the elastic lock and prevents the elastic lock from rotating.
[0008] Furthermore, the connecting seat is installed in the razor body, and a main body interface is opened on the razor body. The lock core is installed on the razor head, and the razor head is connected to the razor body, so that the lock core is connected to the connecting seat through the main body interface, and the lock core is inserted into the connecting seat so that the contact surface of the spring piece is embedded in the lock groove. At the same time, the lock groove presses against the contact surface of the spring piece, and the elastic arm of the spring piece pushes the fastening arm outward to complete the elastic locking function. During this period, the spring piece and the force arm both play a fastening role. When the elastic arm of the spring piece slowly deforms outward, the force arm makes the fastening arm pushed outward closer to the receiving port to compensate for the deformation of the elastic arm of the spring piece. When the elastic arm of the spring piece is completely deformed, the fastening arm fits tightly with the receiving port and can continue to complete the locking function. The razor head is pulled out forcefully to complete the disassembly function.
[0009] Compared with the prior art, the utility model has the beneficial effect that a push-type one-piece elastic lock is used to replace the traditional two-spring insertion structure, and no single insertion installation is required, and it can be directly pushed in with one button, thereby solving the problem of troublesome assembly.
[0010] Another problem is that after the traditional plug-in structure is disassembled and assembled many times, the spring sheet may be deformed, thereby affecting the elasticity, resulting in insufficient fastening force and shortening the service life of the detachable shaver. In the present technology, the spring sheet and the force arm are structurally arranged so that the fastening arm can compensate for the deformation of the spring sheet elastic arm, thereby extending the use time of the locking function and the service life of the detachable shaver. The overall structure of the present innovation is simple, easy to assemble and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS
