Description

Technical Field

[0001] The utility model relates to a lock, in particular to a universal locking structure of a lock. Background Art

[0002] like Figure 5 As shown, a conventional lock comprises a housing, a telescopic push rod disposed in the housing, and a lever. When unlocking or locking, a flat iron bar is inserted into a lever at the bottom end of the lever, driving the lever to rotate. As the lever rotates along the elongated hole of the housing, it squeezes the wall of the elongated hole of the push rod, driving the telescopic push rod and the lock tongue to extend or retract. The lever has end rods at the ends of the lever, which can abut against the walls of the elongated hole to lock and fix the position of the lock tongue. In the above structure, because the end rods need to abut against the walls of the elongated hole after rotation, the end rods are relatively long, and a large portion of the end rods is exposed outside the housing. This causes the end rods to interfere with the inner wall of the lock hole when the diameter of the lock hole on the door is relatively small, and thus cannot be installed in some doors with smaller lock holes.

[0003] Therefore, the applicant has designed a universal locking structure to solve the above problems. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a universal locking structure for a lock.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A universal locking structure includes a telescopic push rod, a shifting rod, and a shifting hole provided in the telescopic push rod. The invention is characterized in that a limiting structure is provided at the end of the shifting rod, and the limiting structure can abut against the hole walls at both ends of the shifting hole to lock the shifting rod.

[0007] The limiting structure is a limiting surface arranged at the end of the shifting rod.

[0008] The limiting surface is a convex arc surface.

[0009] Folding plates are provided at both ends of the dialing hole, and the limiting structure can abut against the lower edge of the folding plate.

[0010] The intersection of the folding plate and the telescopic push rod is bent into an arc shape.

[0011] The utility model also comprises a shell, wherein the shell is provided with a long hole.

[0012] The beneficial effects of the present invention are as follows: the present invention provides a limiting structure at the end of the lever, and the limiting structure can abut against the two ends of the lever hole to lock the lever, so the present application does not need to lock by abutting the end rod against the hole walls at both ends of the long hole, so that the end of the lever can be relatively short and flat, so that when the lever rotates, the part extending outside the long hole is shorter, so as not to interfere with the inner wall of the lock hole, so that the lock can be installed in some doors with small lock holes, thereby greatly increasing the versatility of the lock.

[0019] The advantages and features of the present disclosure and its implementation methods will be illustrated by the following embodiments described with reference to the accompanying drawings. However, the present disclosure can be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be comprehensive and complete and will fully convey the scope of the present disclosure to those skilled in the art. Furthermore, the present disclosure is limited only by the scope of the claims.

[0020] The shapes, sizes, proportions, angles and numbers disclosed in the drawings for describing the embodiments of the present disclosure are merely examples, and therefore the present disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, when a detailed description of a related known function or configuration is determined to be unnecessary to obscure the focus of the present disclosure, the detailed description will be omitted. Where “including”, “having” and “comprising” described in this specification are used, other components may be added unless “only” is used. Unless otherwise indicated, terms in the singular may include plural forms.

[0021] When explaining an element, although not explicitly described, the element is understood to include a range of error.

[0022] When describing a positional relationship, for example, when the positional relationship is described as "on," "above," "below," and "adjacent to," one or more parts may be arranged between two other parts, unless "immediately" or "directly" is used.

[0023] When describing a temporal relationship, for example, when a temporal order is described as “after,” “subsequently,” “next,” and “before,” discontinuous cases may be included unless “just” or “directly” is used.

[0024] It should be understood that although the terms "first," "second," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from other elements. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of this disclosure.

[0025] As will be fully appreciated by those skilled in the art, the features of the different embodiments of the present disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0026] Reference Figures 1 to 4 The utility model discloses a universal lock structure. The lock of the present application is installed in a door 1. A lock hole 2 is provided on the door 1 for installing a lock core. The lock core is connected to the lock by a flat iron bar. The lock includes a telescopic push rod 3, a driving rod 4, and a driving hole 5 is provided in the telescopic push rod 3. The driving hole 5 is a square narrow hole. The end of the driving rod 4 is located in the driving hole 5. The end of the driving rod 4 is provided with a limiting structure. The limiting structure can be against the hole walls at both ends of the driving hole 5 to lock the driving rod 4. The locking can ensure that the lock tongue remains fixed after being extended or retracted, but the flat iron bar drives the driving peach to rotate so that the driving rod 4 is rotated to release the lock.

[0027] As shown in the figure, the limiting structure in this application is preferably a limiting surface 6 set at the end of the shift lever 4. The limiting surface 6 can be a plane. When it is rotated to a certain angle, the plane can be against the edge of the hole wall at both ends of the shift hole 5. As a preferred structure, the limiting surface 6 is a convex arc surface. The limiting surface 6 is slightly raised to form a convex arc surface, and the highest point of the convex arc surface is located at the center of the limiting surface 6, so that the angle of rotation of the shift lever 4 forward and backward can be ensured to be consistent.

[0028] As a further structure, folding plates 7 are provided at both ends of the shift hole 5. The limiting structure can abut against the lower edge of the folding plates 7. Specifically, the limiting surface 6 can abut against the lower edge of the folding plates 7. This can move the locking point of the shift lever 4 downward, reducing the portion of the end of the shift lever 4 exposed from the shift hole 5. As a further structure, the intersection of the folding plates 7 and the telescopic push rod 3 is bent into an arc. The arc can guide the rotation of the shift lever 4, avoiding jamming of the shift lever 4, which may cause the lock tongue to be incompletely extended or retracted. Moreover, the folding plates 7 of the present application are integrally formed with the telescopic push rod 3 by punching and then bending, so they naturally form an arc when bent, which simplifies processing.

[0029] The present application also includes a housing 8, which is provided with a long hole. When the lock is installed, a screw will pass through the long hole 9. The long hole 9 can increase the space to avoid the screw, thereby increasing the versatility of the lock.

[0030] The above is a detailed introduction to a universal lock structure provided by an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
