Description

Technical Field

[0001] The utility model relates to the technical field related to door locks, and in particular to a lock rod installation structure and a door lock system. Background Art

[0002] With the rapid development of smart homes and automated production technologies, the requirements for convenience, safety, and production efficiency of door lock systems are increasing. In traditional door lock systems, the lock rod, as the key component connecting the two handles and achieving the locking function, often relies on manual installation. This not only increases installation difficulty and cost, but also seriously restricts the automation process and efficiency of door lock production.

[0003] Specifically, when installing the locking rod of a traditional door lock, the rod must first be manually threaded through the lock and connected to the handles on both sides. A retaining ring is then manually installed on the rod, snapping into the annular groove on the rod to secure the rod and handle relative to each other, preventing them from falling off during use. This installation method is not only time-consuming and labor-intensive, but also requires high operator skills. It is also prone to uneven installation quality due to human factors, affecting the overall performance and service life of the door lock.

[0004] Furthermore, with the growing market demand for door lock systems, traditional installation methods are no longer able to meet the needs of large-scale, high-efficiency production. On automated production lines, any step requiring manual intervention can become a bottleneck in improving production efficiency. Utility Model Content

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a lock rod installation structure and a door lock system, which can solve the problems of complex installation and the need for manual operation.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A locking rod installation structure comprises: a first handle, the first handle comprising a handle head accommodating cavity and a locking rod insertion cavity, an insertion channel being provided between the handle head accommodating cavity and the locking rod insertion cavity; a snap-fit sleeve, the snap-fit sleeve being provided with a through-hole in the center, a snap-fit lip plate being provided in the through-hole, one end of the snap-fit sleeve being provided with an abutting edge extending outward from the axis, the abutting edge being clamped to an end of the insertion channel close to the handle head accommodating cavity, for limiting the movement of the snap-fit sleeve in a first direction; a locking rod body, a convex component being provided on the locking rod body, the convex component comprising a slope on one side and an abutting surface on the other side, the snap-fit sleeve being sleeved on the locking rod body on one side of the abutting surface, the slope providing a guiding force facilitating the passage of the convex component when the locking rod body is inserted into the through-hole in the opposite direction of the first direction, and the abutting surface facing the first direction, for limiting the movement of the locking rod body in the first direction after being inserted into the through-hole.

[0008] By adopting this solution, and by designing the snap-fit sleeve and the protruding component on the lock rod body, the lock rod and first handle can be quickly and automatically installed. This mechanized snap-fit method reduces human interference and improves installation consistency and reliability, thereby ensuring the overall performance and service life of the door lock. It also adapts well to automated production lines, reduces manual intervention, improves production efficiency, and meets market demand for efficient door lock production systems.

[0009] Furthermore, the convex components are a plurality of snap-fit protrusions provided on the side surface of the locking rod body, and the plurality of snap-fit protrusions are circumferentially arranged along the side surface of the locking rod body and at equal intervals.

[0010] By adopting this solution, the equally spaced engagement protrusions ensure that the lock rod body forms uniform and stable engagement points with the engagement lip when inserted into the engagement sleeve. This multi-point engagement is more secure than single-point or limited-point engagement, effectively preventing the lock rod from accidentally falling off during use and improving installation stability and reliability. Furthermore, the number of engagement protrusions can be increased or decreased, or the spacing between them can be adjusted, to accommodate door lock systems of varying specifications and sizes. This flexibility makes this lock rod installation structure more widely applicable and more competitive in the market.

[0011] Furthermore, the convex component is an annular rib provided on the side surface of the locking rod body.

[0012] By adopting the above solution, a larger contact area and a stronger clamping force are provided, thereby enhancing the connection strength between the locking rod and the handle, and preventing the locking rod from accidentally falling off during use.

[0013] Furthermore, a clamping end is provided at the other end of the locking rod body, and the cross-sectional area of the clamping end is larger than the cross-sectional area of the through hole, so that the clamping sleeve is confined between the clamping end and the protruding component.

[0014] By adopting the above solution, when the locking rod body is inserted into the through hole, the snap-fit end abuts against the other end of the snap-fit sleeve, so that the locking rod body cannot continue to be inserted forward in the opposite direction of the first direction. At this time, the protruding part has passed through the snap-fit lip plate in the through hole, completing the assembly of the locking rod body and the snap-fit sleeve.

[0015] Furthermore, one side of the clamping lip plate is provided with an inclined surface corresponding to the slope surface, and the other side of the clamping lip plate is parallel to the abutting surface.

[0016] By adopting the above solution, the design of the inclined surface enables the slope on the locking rod body to slide over the snap lip plate more easily when inserting the snap sleeve, reducing the resistance and friction during the insertion process, allowing the locking rod to enter the through-hole more smoothly, thereby improving the installation efficiency; when the locking rod body moves in the extraction direction, it will be blocked by the abutment surface, effectively preventing the locking rod from accidentally falling off during use.

[0017] Furthermore, the clamping lip plate and the clamping sleeve are integrally formed, and the convex component and the locking rod body are integrally formed.

[0018] By adopting the above solution, the one-piece design simplifies the production process and reduces the processing steps and assembly links.

[0019] Furthermore, the cross section of the locking rod body is cross-shaped, and there are four clamping protrusions, which are respectively arranged on four side surfaces of the locking rod body.

[0020] By adopting this solution, the cross-shaped cross-section of the lock rod body provides a larger material distribution area, thereby enhancing its resistance to bending and torsion. This structure allows the lock rod to more effectively disperse stress when subjected to external forces, preventing damage caused by localized stress concentration. The specific location of the engaging protrusions can be optimized according to the different structures of the lock rod body.

[0021] Furthermore, the handle head accommodating cavity is provided with an accommodating groove on the periphery of the insertion channel, and the abutting edge is inserted into the accommodating groove.

[0022] By adopting the above solution, after the abutting edge is inserted into the receiving groove, the inner wall of the handle head receiving cavity remains horizontal without any protruding structure, which is more conducive to assembling other parts.

[0023] A door lock system includes a second handle and a lock rod installation structure, one end of the lock rod body is inserted from the first handle in the opposite direction of the first direction and extends into the second handle, and the snap sleeve is located in the first handle.

[0024] By adopting the above solution, a stable connection and smooth transmission between the locking rod body and the handle are achieved, and the limiting installation between the clamping sleeve and the first handle ensures the stable fixation of the locking rod body.

[0025] In summary, the lock rod installation structure and door lock system provided by the present invention have the following technical effects:

[0026] 1. Through the mechanized clamping method, the installation of the lock rod no longer relies on complex manual operations, and can be quickly and accurately installed through automated equipment. This greatly shortens installation time and improves production efficiency, especially suitable for large-scale production scenarios;

[0027] 2. The locking rod installation process is simpler and more direct, reducing specific installation requirements, thereby avoiding labor costs and rework costs caused by installation errors, ensuring that each installation meets the same standards and quality, and improving installation consistency and reliability;

[0028] 3. Through the design of a reasonable snap-on structure and protruding parts, the connection between the lock rod and the handle is more stable, effectively preventing the risk of the lock rod falling off during use, thereby enhancing the safety of the door lock system.

DETAILED DESCRIPTION

[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] Example 1 of the present utility model is shown in FIG. Figures 1-8As shown, a lock rod installation structure is disclosed, including a first handle 4, a clamping sleeve 1 and a lock rod body 2, wherein the first handle 4 includes a handle head accommodating cavity 6 and a lock rod insertion cavity 7, and an insertion channel 8 is provided between the handle head accommodating cavity 6 and the lock rod insertion cavity 7; a through hole 11 is provided in the center of the clamping sleeve 1, and a clamping lip plate 111 is provided in the through hole 11, and an abutting edge 12 is extended outward from the axis of one end of the clamping sleeve 1, and the abutting edge 12 is clamped to an end of the insertion channel 8 close to the handle head accommodating cavity 6, so as to limit the movement of the clamping sleeve 1 in the first direction; an outer The convex component 3 includes a sloped surface 31 on one side and an abutting surface 32 on the other side. The snap-fit sleeve 1 is mounted on the locking rod body 2 on one side of the abutting surface 32. The sloped surface 31 provides a guiding force that facilitates the passage of the convex component 3 when the locking rod body 2 is inserted into the through-hole 11 in a direction opposite to the first direction. The abutting surface 32 faces the first direction and is used to limit the movement of the locking rod body 2 in the first direction after insertion into the through-hole 11. By designing the snap-fit sleeve 1, the first handle 4, and the convex component 3 on the locking rod body 2, rapid and automated installation of the locking rod is achieved. The mechanized snap-fit method reduces human interference, improves installation consistency and reliability, and thus ensures the overall performance and service life of the door lock. At the same time, it can well adapt to automated production lines, reduce manual intervention links, improve production efficiency, and meet the market demand for efficient production of door lock systems.

[0043] It should be noted that the engaging lip plate 111 in the through-hole 11 is provided along the circumference of the through-hole 11 and is made of an elastically deformable material, which may also be a flexible material such as silicone or rubber. This allows the engaging lip plate 111 to generate an interference force on the protruding component 3 when the locking rod body 2 is inserted into the through-hole 11.

[0044] In some embodiments, the protruding member 3 preferably comprises a plurality of engaging protrusions 33 disposed on the side of the lock bar body 2. These engaging protrusions 33 are arranged circumferentially and at equal intervals along the side of the lock bar body 2. These equally spaced engaging protrusions 33 ensure that the lock bar body 2 forms uniform and stable engagement points with the engaging lip plate 111 when inserted into the engaging sleeve 1. This multi-point engagement is more secure than a single or limited-point engagement, effectively preventing the lock bar from accidentally falling off during use and improving installation stability and reliability. Furthermore, the number of engaging protrusions 33 can be increased or decreased, or the spacing between them can be adjusted, to accommodate door lock systems of varying specifications and sizes. This flexibility enables the lock bar installation structure to have a wider range of applications and greater market competitiveness.

[0045] In some embodiments, the protruding member 3 can optionally be an annular rib provided on the side of the locking rod body 2, which can provide a larger contact area and a stronger clamping force, thereby enhancing the connection strength between the locking rod and the handle and preventing the locking rod from accidentally falling off during use. In this structure, the clamping lip plate 111 can optionally be provided with multiple notches to reduce the rigid connection between the two and avoid problems such as difficulty in insertion.

[0046] In order to avoid over-installation of the locking rod body 2, which causes the locking rod to be inserted too much into the socket, in some embodiments, a clamping end 21 is provided at the other end of the locking rod body 2, and the cross-sectional area of the clamping end 21 is larger than the cross-sectional area of the locking rod body 2. At the same time, the cross-sectional area of the clamping end 21 is larger than the area of the through-hole 11, so that the clamping end 21 cannot continue to move forward when the locking rod body 2 is inserted into the through-hole 11. When the locking rod body 2 is inserted into the through-hole 11, the clamping end 21 abuts against the other end of the clamping sleeve 1, so that the locking rod body 2 cannot continue to be inserted forward in the opposite direction of the first direction. The clamping sleeve 1 is restricted between the clamping end 21 and the protruding part 3. At this time, the protruding part 3 has passed through the clamping lip plate 111 in the through-hole 11, completing the assembly of the locking rod body 2 and the clamping sleeve 1.

[0047] In this embodiment 1, since the snap lip 111 is made of a flexible material, in order to improve the strength of the snap lip 111 and thus increase the abutting force against the abutting surface 32, an inclined surface 1111 is provided on one side of the snap lip 111 corresponding to the slope 31, and the other side of the snap lip 111 is parallel to the abutting surface 32. The design of the inclined surface 1111 enables the slope 31 on the locking rod body 2 to slide over the snap lip 111 more easily when inserting the snap sleeve 1, thereby reducing the resistance and friction during the insertion process, allowing the locking rod to enter the through-hole 11 more smoothly, thereby improving the installation efficiency; when the locking rod body 2 moves in the extraction direction, it will be blocked by the abutting surface 32, effectively preventing the locking rod from accidentally falling off during use, and the design of the inclined surface 1111 provides a stable support effect for the side of the snap lip 111 in contact with the abutting surface 32, similar to a dam structure.

[0048] Optionally, the handle head accommodating cavity 6 is provided with an accommodating groove 61 around the insertion channel 8, and the abutting edge 12 is snapped into the accommodating groove 61. After the abutting edge 12 is snapped into the accommodating groove 61, the inner wall of the handle head accommodating cavity 6 remains horizontal and there is no protruding structure, which is more conducive to assembling other parts, such as the handle head 9.

[0049] The present invention also relates to a door lock system, including a second handle 5 and a locking rod installation structure, one end of the locking rod body 2 is inserted from the first handle 4 in the opposite direction of the first direction and extends into the second handle 5, the snap sleeve 1 is limited in the first handle 4, and since the handle head accommodating cavity 6 is fixedly installed with the handle head 9, the snap sleeve 1 can be tightened, thereby achieving a stable connection and smooth transmission between the locking rod body 2 and the handle, so that a stable and convenient operating environment is formed inside the first handle 4, and the snap sleeve 1 can be limited, thereby achieving a limiting effect on the locking rod.

[0050] Preferably, the snap-fit lip plate 111 and the snap-fit sleeve 1 are integrally formed, and the protruding component 3 and the locking rod body 2 are integrally formed. The integrally formed design simplifies the production process and reduces processing steps and assembly links.

[0051] In this first embodiment, the locking rod body 2 has a cross-shaped cross-section, and four engaging protrusions 33 are provided, one on each of the four sides of the locking rod body 2. The cross-shaped cross-section of the locking rod body 2 provides a larger material distribution area, thereby enhancing its resistance to bending and torsion. This structure allows the locking rod to more effectively disperse stress when subjected to external forces, preventing damage caused by localized stress concentration. The engaging protrusions 33 can be appropriately positioned based on the different structures of the locking rod body 2. In other embodiments, the structure and number of engaging protrusions 33 can be specifically configured based on the structure of the locking rod body 2. This embodiment does not impose any specific restrictions, as long as the engaging effect is achieved.

[0052] In summary, the lock rod installation structure and door lock system provided by the present invention have the following technical effects:

[0053] 1. Through the mechanized clamping method, the installation of the lock rod no longer relies on complex manual operations, and can be quickly and accurately installed through automated equipment. This greatly shortens installation time and improves production efficiency, especially suitable for large-scale production scenarios;

[0054] 2. The locking rod installation process is simpler and more direct, reducing specific installation requirements, thereby avoiding labor costs and rework costs caused by installation errors, ensuring that each installation meets the same standards and quality, and improving installation consistency and reliability;

[0055] 3. Through the rational design of the snap-fit structure and the protruding component 3, the connection between the lock rod and the handle is more stable, effectively preventing the risk of the lock rod falling off during use, thereby enhancing the safety of the door lock system.

[0056] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
