Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a push-button lock box. Background Technology

[0002] In the field of lock installation, snap-on boxes (also known as strike plates or latch boxes) are widely used for the installation of latches on door frames of wooden doors, metal doors, and other door types. Traditional snap-on boxes typically consist of a box body with a latch groove for the latch to extend into. Both ends of the box body along its length are equipped with elastic retaining structures (such as spring clips). During installation, the box body is pressed into the pre-set mounting holes on the door frame, and the retaining force generated by the outward expansion of the spring clips achieves a fixed connection with the mounting holes.

[0003] However, the aforementioned traditional structure has significant drawbacks in actual installation. Because the spring tabs at both ends of the lock body are outwardly extended, the installer needs to press the entire lock body into the mounting hole. During this pressing process, the spring tabs are squeezed by the inner wall of the mounting hole and converge towards the lock body. After the lock body is fully inserted into the mounting hole, the spring tabs spring back and lock into the edge of the mounting hole opening. However, because it is difficult to ensure absolute balance during the pressing operation, the lock body is prone to tilting when entering the mounting hole. Once tilted, the spring tab at the first end may flip outward due to excessive pressure, causing the outward-flipped part of the spring tab to detach from the opening of the mounting hole. This results in the lock body not being properly installed, leaving a gap between it and the door frame, which can easily lead to loosening, shaking, and even abnormal noise, severely affecting the user experience of the lock. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a press-fit buckle box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a press-fit buckle box, comprising a buckle box body, wherein a locking tongue groove is provided on the buckle box body, and elastic retaining members and rigid abutting blocks are respectively connected to both ends of the buckle box body along its own length direction; the elastic retaining member includes a connecting section fixed to the buckle box body and a retaining section extending obliquely from the connecting section in a direction away from the buckle box body, wherein an avoidance space is formed between the retaining section and the buckle box body for the retaining section to undergo elastic deformation.

[0006] By adopting the above technical solution, during installation, the rigid abutment block is first tilted and inserted into the mounting hole, resting against the lower inner wall of the mounting hole. The rigid abutment block provides a stable positioning reference. Then, the elastic retaining member is pressed, causing the retaining section to elastically deform within the clearance space and converge towards the buckle body. After the buckle body is fully inserted into the mounting hole, the retaining section elastically resets and retains itself against the inner wall of the mounting hole opening. This structure overcomes the problems of traditional structures with spring tabs at both ends, which tend to tilt due to uneven force during pressing, and one end of the spring tab flipping outwards and detaching from the mounting hole opening. This ensures a smooth and reliable installation process, allowing the buckle body to be accurately installed, effectively avoiding shaking and abnormal noise caused by improper installation, and is also easy to operate.

[0007] As a preferred technical solution of this utility model, the bottom of the buckle box body is provided with a pressure plate, and the connecting section extends to the bottom of the buckle box body and is fixed to the buckle box body by the pressure plate.

[0008] By adopting the above technical solution, the connecting section of the elastic retaining component is extended to the bottom of the buckle box body and fixed by a pressure plate, achieving a detachable fixed connection between the elastic retaining component and the buckle box body. This structure facilitates the independent processing and replacement of the elastic retaining component, reducing manufacturing and maintenance costs. Furthermore, the pressure plate pressing method ensures a large surface contact between the connecting section and the bottom of the buckle box body, resulting in a firm and reliable fixation. This effectively prevents the elastic retaining component from shifting or loosening during use, ensuring long-term stability.

[0009] As a preferred technical solution of this utility model, the pressure plate includes a plate body and a hook portion extending upward from one end of the plate body. One end of the buckle box body is provided with a slot for the hook portion to be engaged. The plate body is attached to the bottom of the buckle box body and located outside the connecting section, and the plate body is fixedly connected to the buckle box body by a first fastening screw.

[0010] By adopting the above technical solution, the structure forms a dual fixing mechanism of bottom screw locking and end hook limiting, which makes the positioning of the pressure plate on the buckle box body more accurate and the connection more stable; and the hook part can be pre-positioned before the screw is tightened, which facilitates the assembly operation and improves the assembly efficiency.

[0011] As a preferred embodiment of the present invention, the hook portion includes a vertical section and a bent portion that bends from the upper end of the vertical section toward the buckle body. The vertical section is attached to the outer wall of the buckle body, and the bent portion extends into the slot.

[0012] By adopting the above technical solution, the bent part extends into the slot to form a hook engagement, which is simple and compact in structure. It can achieve a reliable connection between the end of the pressure plate and the buckle box body without the need for additional fasteners. At the same time, it is extremely convenient to assemble and disassemble, which is conducive to quick disassembly and assembly during later maintenance.

[0013] As a preferred technical solution of this utility model, the plate body and the connecting section are respectively provided with corresponding connecting holes, and the first fastening screw passes through the two connecting holes in sequence and is threadedly connected to the threaded hole on the buckle box body.

[0014] By adopting the above technical solution, coaxial fastening of the plate, connecting section, and buckle box body is achieved. This structure allows the first fastening screw to simultaneously and firmly fix the pressure plate and connecting section to the buckle box body during the tightening process. The connecting section is clamped and fixed between the plate and the bottom of the buckle box body, resulting in good stress distribution and preventing loosening.

[0015] As a preferred embodiment of this utility model, the rigid abutment block is wedge-shaped.

[0016] By adopting the above technical solution, once the buckle box body is installed in place, the wedge-shaped protrusion is always confined to the inner wall of the mounting hole by the elastic retaining member.

[0017] As a preferred technical solution of this utility model, the buckle box body includes a frame and a buckle plate disposed in the frame. The frame has an installation cavity and an opening above the installation cavity. Windows are respectively opened on the opposite side walls on both sides of the opening on the frame. The buckle plate has a locking tongue groove facing the opening, and the buckle plate can move within the range of the window and lock to the buckle box body.

[0018] By adopting the above technical solution, the structure makes the position of the buckle plate relative to the frame adjustable, and flexibly adjusts the position of the buckle plate in the frame, thereby precisely adjusting the tightness of the fit between the latch groove and the latch, ensuring that the latch can smoothly enter and exit the latch groove, while avoiding the latch from getting stuck due to excessive tightness or the door from shaking due to excessive looseness.

[0019] As a preferred technical solution of this utility model, the buckle plate has elongated holes at both ends along its length, the buckle box body has a first through hole corresponding to the two elongated holes, and the pressure plate has internal threaded holes at both ends corresponding to the two first through holes.

[0020] By adopting the above technical solution, after loosening the first fastening screw, the retaining plate can slide and adjust along the length of the elongated hole, and after locking, it is fixed in the adjusted position. The adjustment range is controllable, and the adjustment operation can be completed simply by loosening and tightening the screw, without disassembling any parts, making the adjustment process extremely convenient and quick.

[0021] As a preferred technical solution of this utility model, the buckle plate has a groove on the side facing away from the locking tongue groove, and the press buckle box also includes a magnetic suction component, which is fixed between the buckle plate and the inner wall of the buckle box body and located in the groove.

[0027] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1 to 10 The push-button snap box shown includes a snap box body 1, on which a locking tongue groove 2 is provided. An elastic retaining member 3 and a rigid abutting block 4 are respectively connected to both ends of the snap box body 1 along its length direction. The elastic retaining member 3 includes a connecting section 5 fixed to the snap box body 1 and a retaining section 6 extending obliquely from the connecting section 5 away from the snap box body 1. A clearance space 7 is formed between the retaining section 6 and the snap box body 1, allowing the retaining section 6 to undergo elastic deformation.

[0030] During installation, first, tilt one side of the rigid abutment block 4 into the mounting hole and place it against the lower inner wall of the mounting hole. The rigid abutment block 4 provides a stable positioning reference. Then, press one side of the elastic retaining member 3, causing the retaining section 6 to elastically deform within the clearance space 7 and converge towards the buckle body 1. After the buckle body 1 is fully inserted into the mounting hole, the retaining section 6 elastically resets and is held in place against the inner wall of the mounting hole opening. This structure overcomes the problem of uneven force during pressing in traditional structures with spring tabs at both ends, which can cause tilting and one end of the spring tab to flip outward and detach from the mounting hole opening. This ensures a smooth and reliable installation process, allowing the buckle body 1 to be accurately installed in place, effectively avoiding shaking and abnormal noise caused by improper installation, and is also easy to operate.

[0031] A pressure plate 8 is provided at the bottom of the snap-fit ​​box body 1. The connecting section 5 extends to the bottom of the snap-fit ​​box body 1 and is pressed and fixed to the snap-fit ​​box body 1 by the pressure plate 8. Extending the connecting section 5 of the elastic retaining member 3 to the bottom of the snap-fit ​​box body 1 and fixing it by the pressure plate 8 realizes a detachable fixed connection between the elastic retaining member 3 and the snap-fit ​​box body 1. This structure facilitates the independent processing and replacement of the elastic retaining member 3, reducing manufacturing and maintenance costs. On the other hand, the pressing method of the pressure plate 8 allows the connecting section 5 to form a large surface contact with the bottom of the snap-fit ​​box body 1, ensuring a firm and reliable fixation. This effectively prevents the elastic retaining member 3 from shifting or loosening during use, ensuring long-term stability.

[0032] The pressure plate 8 includes a plate body 10 and a hook portion 9 extending upward from one end of the plate body 10.
