Description

Technical Field

[0001] The utility model relates to the technical field of door and window locks, and in particular to a swing door lock, a kit and a door system. Background Art

[0002] In the traditional design of swing door locks, vertically installed lock body components are widely used. The lock body components are directly installed inside the door frame profile, which makes the overall width of the door frame larger, taking up too much space and affecting the aesthetics of the door. In order to improve this problem, some manufacturers have proposed a solution of horizontally installing the lock body components. This solution allows the lock body components to pass horizontally through the outer surface of the door frame, and part of the lock body components are located outside the inner side of the door frame, effectively reducing the width of the door frame.

[0003] However, this horizontal installation solution also has some problems. In order to keep the lock body assembly fixed, a limiting structure is set at the outer end of the lock body assembly, and a socket is set on the outside of the lock body assembly on the inner side of the door frame. During the installation process, the plug needs to be inserted into the lock body assembly and fixed against the door frame by horizontally installed screws to ensure that the lock body assembly does not move or fall off. However, these screws used for fixing are usually hexagonal, horizontally located and close to the lock body assembly, which brings great inconvenience to the installation operation. The installer needs to use a specific elbow tool to operate in a small space. The locking range of the elbow tool is small each time, which not only increases the difficulty of installation, but also greatly reduces the installation efficiency. In another direction, this installation method uses screws to tighten and fix. After a certain period of use, the lock is easy to loosen.

[0004] In order to solve these problems, we urgently need a new type of swing door lock installation structure, which aims to simplify the installation steps, improve the installation efficiency, and maintain the stability and safety of the lock body assembly. Summary of the invention

[0005] One purpose of the utility model is to solve the problems of cumbersome installation and operation of lock body components, low efficiency, and easy loosening of locks in the prior art, and the lock body components are positioned by configuring a pin hole positioning structure in the first cover assembly and the second cover assembly.

[0006] The solution adopted by this patent is as follows:

[0007] A swing door lock comprises: a lock body assembly, a first face cover assembly, a second face cover assembly and a pin hole positioning structure; the pin hole positioning structure is arranged between the first face cover assembly, the second face cover assembly and the lock body assembly; when the first face cover assembly and the second face cover assembly are clamped and connected, the lock body assembly is positioned by the cooperation of the pin hole positioning structure.

[0008] The invention uses the cooperation of the pin hole positioning structure to position the lock body assembly while the first cover assembly and the second cover assembly are clamped and connected. The structure is simple, the installation steps are simplified, and it is convenient and quick. In addition, the cooperation of the pin hole positioning structure has good rigidity, good stability and high safety.

[0009] Furthermore, in one solution of the present application, the pin hole positioning structure includes one or more positioning pins respectively configured on the first cover assembly and the second cover assembly, and one or more positioning holes correspondingly configured on the lock body assembly. When the first cover assembly and the second cover assembly are clamped and connected, the positioning pins are inserted into the corresponding positioning holes. With the above solution, it is easier to simplify the processing of the positioning holes in the lock body assembly, and the positioning holes are used as the positioning reference, so the assembly accuracy is better.

[0010] Furthermore, the positioning pins on the first cover assembly and the second cover assembly are arranged opposite to each other, and when the first cover assembly and the second cover assembly are clamped and connected, the positioning pins on both sides of the same positioning hole are inserted. With the above solution, the assembly accuracy of the first cover assembly and the second cover assembly is further improved, and the number of positioning holes required is reduced.

[0011] Of course, as a second solution, the positioning pins on the first cover assembly and the second cover assembly are staggered, and when the first cover assembly and the second cover assembly are clamped together, the positioning pins of the two can be inserted into different positioning holes for positioning cooperation, which can also achieve the positioning effect.

[0012] Furthermore, the positioning pin is provided with a cylindrical positioning portion, the positioning hole is provided with a tapered wall and a cylindrical positioning wall along the insertion direction of the positioning pin, and the outer end of the positioning pin is provided with a guide portion for convenient insertion into the positioning hole. The tapered wall and the guide portion facilitate the installation of the first cover assembly and the second cover assembly, and the cylindrical positioning wall and the cylindrical positioning portion ensure the matching accuracy.

[0013] Furthermore, the locating pin is threadedly connected to the locating column connection holes of the first cover assembly and the second cover assembly through the threaded portion, and the head of the locating pin is provided with a tool coupling portion for assembly. The locating pin is manufactured by separate parts processing, which can better ensure the quality and rigidity, and the material selection is better.

[0014] In the third scheme of the present application, the pin hole positioning structure includes one or more positioning pins integrally or separately configured on the lock body assembly and extending from both sides, and one or more positioning holes correspondingly configured on the first face cover assembly and the second face cover assembly. When the first face cover assembly and the second face cover assembly are clamped and connected, the positioning pins are inserted into the corresponding positioning holes.

[0015] Furthermore, the first surface cover assembly and the second surface cover assembly are connected by screws, the first surface cover assembly is provided with a first transmission connection part corresponding to the transmission hole, and the second surface cover assembly is provided with a second transmission connection part corresponding to the transmission hole.

A limit socket a3.1 is provided at the front of the lock body assembly a3, and the limit socket a3.1 is equipped with an insert block a3.2. After the insert block a3.2 is inserted into the limit socket a3.1, both ends of the insert block a3.2 extend out of the opposite sides of the lock body assembly a3, and threaded holes for threaded coupling with a threaded lock column a3.3 extending along the length direction of the lock body assembly are provided at both ends of the insert block a3.2.

[0033] It should be noted that the attached Figure 5 To Attachment Figure 7 The shape of the middle door body d' is a simplified representation and is not a specific shape.

[0034] like Figures 4 to 7 As shown, the frame d.1' of the door body d' where the door lock is installed is provided with a stepped frame assembly hole d01', and the door body d' is provided with a lock body assembly groove d0' adapted to the shape of the lock body assembly a3 corresponding to the frame assembly hole d01'.

[0035] The first cover body a1.1 of the first cover assembly a1 is provided with connecting columns a1.10 on both sides of the transmission hole a3.11, the lock body assembly a3 is provided with assembly avoidance holes a3.10 corresponding to the connecting columns a1.10, and the second cover body a2.1 of the second cover assembly a2 is provided with corresponding connecting holes. The first cover body a1.1 and the second cover body a2.1 are provided with first transmission connecting parts a1.11 and first transmission connecting parts a2.11 respectively corresponding to the transmission hole a3.11.

[0036] During installation, after the lock body assembly a is installed into the assembly groove d0' through the frame assembly hole d01', the limiting step a30 of the lock body assembly a3 cooperates with the step of the frame assembly hole d01' to limit the lock body assembly a3 from moving toward the assembly groove d0'; insert the plug a3.2 into the limiting plug hole a3.1, and then install the threaded lock column a3.3 into the threaded holes at both ends of the plug a3.2, and use a tool to rotate the threaded lock column a3.3 and push it against the frame d.1' of the door body d' to limit the lock body assembly a3 from moving outward, thus achieving the installation of the lock body assembly a3. Then install the first cover assembly a1 and the second cover assembly a2, and connect the screw a4 through the corresponding connection hole of the second cover assembly a2 and the connection column a1.10, so that the first cover assembly a1 and the second cover assembly a2 clamp the door body d'.

[0037] like Figure 3 As shown, the first handle assembly a6 and the second handle assembly a7 are respectively mounted on the first cover assembly a1 and the second cover assembly a2, and one end of the square shaft a7.11 can be first connected to a handle assembly therein, such as the second handle assembly a7, and then sequentially pass through a2.11 of the second cover body a2.1, the transmission hole a3.11 and the transmission assembly hole a1.11 of the first cover body a1.1 and then connected to the first handle assembly a6. Of course, in other embodiments, the square shaft a7.11 can be first mounted to the first handle assembly a6.

[0038] The above is a general structure of a horizontally mounted swing door lock in the prior art. When installing the lock body assembly a3, the threaded lock cylinder a3.3 is located horizontally and close to the lock body assembly a3, which brings great inconvenience to the installation operation. The installer needs to use a specific elbow tool to perform the operation in a narrow space, and the locking range of the elbow tool is small each time, which not only increases the difficulty of installation, but also greatly reduces the installation efficiency.

[0039] A swing door lock comprises: a lock body assembly 3, a first cover assembly 1, a second cover assembly 2 and a pin hole positioning structure 5, 3.5; the lock body assembly 3 is constructed with a transmission hole 3.11 penetrating both sides; the first cover assembly 1 is provided with a first transmission connection part 1.11 corresponding to the transmission hole 3.11; the second cover assembly 2 is provided with a second transmission connection part 2.11 corresponding to the transmission hole 3.11; the pin hole positioning structure 5, 3.5 is arranged between the first cover assembly 1, the second cover assembly 2 and the lock body assembly 3; when the first cover assembly 1 and the second cover assembly 2 are clamped and connected, the lock body assembly 3 is positioned by the cooperation of the pin hole positioning structure 535. One solution of the first cover assembly 1 and the second cover assembly 2 is to connect them by screws 4.

[0040] The present application uses the cooperation of the pin hole positioning structure 535 to position the lock body assembly 3 while the first cover assembly 1 and the second cover assembly 2 are clamped and connected. The structure is simple, the installation steps are simplified, and it is convenient and quick. In addition, the pin hole positioning structure 535 has good rigidity, good stability and high safety.

With the above solution, it is easier to simplify the processing of the positioning holes 3.5 in the lock body assembly 3, and the positioning holes 3.5 are used as the positioning reference, and the assembly accuracy is better.

[0043] The positioning pins 5 on the first cover assembly 1 and the second cover assembly 2 are arranged opposite to each other. When the first cover assembly 1 and the second cover assembly 2 are clamped and connected, the positioning pins 5 opposite to each other are inserted into the two sides of the same positioning hole 3.5. With the above solution, the assembly accuracy of the first cover assembly 1 and the second cover assembly 2 is further improved, and the number of positioning holes 3.5 needs to be less.

Of course, in other embodiments, the number of positioning holes 3.5 can be configured to be one or three or more. Of course, too many numbers will affect the space for other parts of the product, which can be determined based on the spatial size and positioning requirements of the product. Generally, two positioning holes 3.5 and two positioning holes 5 in the first cover assembly 1 and the second cover assembly 2 are respectively sufficient.

The locating pin 5 is manufactured by split-part processing, which can better ensure quality and rigidity, and has better material selection.

[0047] In some other embodiments, the positioning pins 5 on the first cover assembly 1 and the second cover assembly 2 are staggered. When the first cover assembly 1 and the second cover assembly 2 are clamped and connected, the positioning pins 5 of the two can be inserted into different positioning holes 3.5 for positioning cooperation to achieve the positioning effect.

[0048] In some other embodiments, the pin hole positioning structure includes one or more positioning pins integrally or separately configured on the lock body assembly 3 and extending from both sides, and one or more positioning holes correspondingly configured on the first face cover assembly 1 and the second face cover assembly 2. When the first face cover assembly 1 and the second face cover assembly 2 are clamped and connected, the positioning pins are inserted into the corresponding positioning holes.

[0049] Specifically, the positioning pin can be two parts integrally formed with the two sides of the lock body component 3, such as die casting or injection molding; or a mounting hole can be set on the lock body component 3, and the positioning pin is fixed to the lock body component 3 through the mounting hole and the two ends extend out of the two sides of the lock body component 3.
