Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically to a lock. Background Technology

[0002] As an important component of building safety facilities, the stability and ease of installation of stair handrails directly affect safety and construction efficiency.

[0003] When stair handrails are positioned using clamps, the distance between the clamps and the set position is not adjustable. This makes it difficult to adapt to stair handrails of different sizes during installation, and it is difficult to adjust the relative position of the handrail and the set position. It is necessary to customize clamps of different specifications or perform on-site processing, which increases construction costs and time. In addition, the connection stability may be affected by the spacing error, which may pose a safety hazard. Utility Model Content

[0004] In view of this, the present invention provides a lock to solve the problem that traditional stair handrails are mostly installed and fixed by welding, which depends on the skills of construction personnel and results in low installation efficiency.

[0005] This utility model provides a lock, including:

[0006] A locking structure having an open position and a closed position, wherein when the locking structure is in the closed position, the locking structure is ring-shaped and suitable for fitting and positioning onto a first workpiece;

[0007] A connecting seat, which is connected to a locking structure, is adapted to be positioned onto a second workpiece;

[0008] The locking structure is slidably mounted on the connecting seat, and the locking structure can be adjusted by the adjusting structure.

[0009] The beneficial effects of the above-mentioned lock are as follows: By sliding the locking structure onto the connecting seat and adjusting it via the adjustment mechanism, the position of the locking structure relative to the connecting seat can be adjusted to accommodate first workpieces of different sizes or installation positions, thus solving the problem of difficult adaptation caused by the non-adjustable spacing of traditional clamps; at the same time, the sliding adjustment method is convenient to operate, making it easy to accurately adjust the position of the locking structure according to actual needs, ensuring the stability and accuracy of the connection between the first and second workpieces, avoiding the impact of spacing errors on connection stability, reducing the need for customized clamps of different specifications or on-site processing, reducing construction costs and time, and improving the overall installation adaptability and security.

[0010] In one optional embodiment, the locking structure is slidably mounted on the connecting seat. The locking structure can be adjusted via an adjustment mechanism to change its position relative to the connecting seat, thereby adapting to workpieces of different sizes or installation positions and enhancing the lock's versatility and installation flexibility. Simultaneously, the sliding adjustment method is convenient to operate, allowing for precise adjustment of the locking structure's position according to actual needs, ensuring the stability and accuracy of the connection between the first and second workpieces, and improving overall installation adaptability.

[0011] In one optional implementation, the adjustment structure includes:

[0012] An adjusting screw, which is rotatably mounted on a connecting seat;

[0013] A screw positioning seat is threadedly fitted to an adjusting screw and fixedly connected to a locking structure. When the adjusting screw is rotated, the screw positioning seat drives the locking structure to slide on the connecting seat to adjust the locking structure.

[0014] The beneficial effects of the above technical solution are as follows: By adjusting the threaded engagement between the adjusting screw and the screw positioning seat, the rotational motion of the adjusting screw is converted into the linear motion of the screw positioning seat, thereby driving the locking structure to slide along the connecting seat, achieving precise adjustment of the locking structure's position. This structure utilizes the self-locking characteristic of threaded transmission to stably maintain the position of the locking structure after adjustment, preventing loosening. Simultaneously, the operation of rotating the adjusting screw is intuitive and convenient, allowing construction personnel to quickly adjust according to the relative positions of the first and second workpieces, further improving the fitting accuracy and operational efficiency during lock installation.

[0015] In one optional embodiment, the adjusting screw includes a screw section and a nut section, the screw section being connected to the nut section, and the screw positioning seat being threadedly fitted to the screw section;

[0016] The connecting seat is provided with a screw connecting seat, the screw connecting seat is provided with a through hole, the screw section passes through the through hole and is threadedly connected with a limit nut, and the nut section and the limit nut are located on both sides of the screw connecting seat.

[0017] In one alternative embodiment, the locking structure includes:

[0018] Clamps;

[0019] A clamp locking component is disposed on the clamp and is suitable for controlling the opening and closing of the clamp;

[0020] The plug-in part is connected to the clamp.

[0021] In one optional embodiment, the connector is provided with a plug-in cavity that mates with the plug-in part, and the plug-in part is inserted into the plug-in cavity.

[0023] The beneficial effects of the above technical solution are as follows: through the cooperation of the limiting rod and the limiting cavity, the sliding stroke of the locking structure can be precisely limited, effectively preventing the locking structure from disengaging from the connecting seat due to excessive movement during the sliding adjustment process, thus ensuring the safety and stability of the sliding adjustment.

[0024] In one optional embodiment, the clamp is provided with at least one fitting part, the inner wall surface of which is a friction surface, which can significantly increase the friction with the surface of the first workpiece, effectively preventing the clamp from sliding or rotating relative to the first workpiece after fitting, and ensuring the clamping stability of the first workpiece; at the same time, the friction surface can disperse the contact pressure and avoid local stress concentration that could cause damage to the workpiece surface.

[0025] In one alternative embodiment, the clamp is formed by wrapping around a plate from end to end; the clamp locking component includes a ring and a locking bolt, the head and tail ends of the clamp overlap and are wrapped by the ring, the locking bolt is disposed on the ring, and the locking bolt cooperates with the inner wall of the ring to lock the head and tail ends of the clamp.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] According to an embodiment of this utility model, a lock is provided, combined with Figures 1 to 6 As shown, it includes a locking structure 1 and a connecting seat 2. The locking structure 1 has an open position and a closed position. When the locking structure 1 is in the closed position, it is annular and suitable for fitting and positioning onto a first workpiece. The connecting seat 2 is connected to the locking structure 1 and is suitable for positioning onto a second workpiece.

[0042] In the aforementioned lock, the locking structure 1 is slidably mounted on the connecting seat 2. The locking structure 1 can be adjusted via the adjusting structure 3, allowing for positional adjustment relative to the connecting seat 2. This adapts to workpieces of different sizes or installation positions, enhancing the lock's versatility and installation flexibility. Furthermore, the sliding adjustment method is convenient, facilitating precise adjustment of the locking structure 1 according to actual needs, ensuring the stability and accuracy of the connection between the first and second workpieces, and improving overall installation compatibility.

[0043] The aforementioned lock, through its locking structure 1 having open and closed positions, achieves a non-welding, rapid connection and fixation between the first and second workpieces by fitting a ring-shaped assembly in the closed position and engaging with a connecting seat that positions and connects to the second workpiece. Compared to traditional welding installation methods, this eliminates the need for specialized welding tools and processes, reducing reliance on skilled workers, effectively simplifying the installation process, and significantly improving installation efficiency. Furthermore, the locking structure's opening and closing operations are convenient, facilitating quick assembly and disassembly of the first and second workpieces and subsequent adjustments and maintenance. The overall structure is simple and highly practical.

[0044] The above-mentioned lock can be applied to stair handrails. The locking structure 1 can be sleeved on the stair handrail and the stair handrail can be connected to the position to be positioned through the connecting seat 2; or after the locking structure 1 is sleeved on the stair handrail, the second workpiece is positioned on the connecting seat 2 to realize the positioning of other parts on the stair handrail.

[0045] The locking structure 1 features a ring-shaped design made of high-strength iron, ensuring uniform clamping force when installing the stair railing. The positioning part 22 includes mounting holes and nuts, facilitating quick fixation to the desired location or other secondary components, such as railing supports or decorative accessories, using bolts or clips, enabling multi-functional applications. During installation, the user can first adjust the locking structure 1 to the closed position, insert the stair railing, tighten it, and then connect and position the connecting seat 2. Furthermore, this lock supports repeated disassembly and reassembly without the need for additional tools.

[0046] In some embodiments, the adjusting structure 3 includes an adjusting screw 32 and a screw positioning seat 34. The adjusting screw 32 is rotatably mounted on the connecting seat 2. The screw positioning seat 34 is threadedly fitted to the adjusting screw 32 and is fixedly connected to the locking structure 1. When the adjusting screw 32 is rotated, the screw positioning seat 34 causes the locking structure 1 to slide on the connecting seat 2, thereby adjusting the locking structure 1.

[0047] In this embodiment, by adjusting the threaded engagement between the adjusting screw 32 and the screw positioning seat 34, the rotational motion of the adjusting screw 32 is converted into the linear motion of the screw positioning seat 34, thereby driving the locking structure 1 to slide along the connecting seat 2, achieving precise adjustment of the position of the locking structure 1. This structure utilizes the self-locking characteristic of threaded transmission to stably maintain the position of the locking structure 1 after adjustment, preventing loosening. At the same time, the operation of rotating the adjusting screw 32 is intuitive and convenient, allowing construction personnel to quickly adjust according to the relative position requirements of the first and second workpieces, further improving the fitting accuracy and operational efficiency during lock installation.

[0048] The adjusting screw 32 includes a screw section 321 and a nut section 322, which are connected. The screw section 321 and the nut section 322 are threaded together, and the screw positioning seat 34 is threadedly fitted to the screw section 321. A screw connecting seat 31 is provided on the connecting seat 2, and a through hole is provided on the screw connecting seat 31. The screw section 321 passes through the through hole and is threadedly connected to a limit nut 33. The nut section 322 and the limit nut 33 are located on both sides of the screw connecting seat 31, thereby allowing the adjusting screw 32 to be rotatably connected to the connecting seat 2. The limit nut 33 and the nut section 322 restrict the overall position of the adjusting screw 32, so that when the adjusting screw 32 rotates, it only rotates within its fixed area and does not undergo linear movement.

[0049] In some embodiments, the locking structure 1 includes a clamp 11, a clamp locking member 12, and a plug-in portion 14. The clamp locking member 12 is disposed on the clamp 11 and is adapted to control the opening and closing of the clamp 11 to achieve quick mounting and dismounting of the first workpiece. The plug-in portion 14 is connected to the clamp 11. The clamp 11 is annular.

[0050] The connector 2 is provided with a plug cavity 21 that mates with the plug part 14, and the plug part 14 is inserted into the plug cavity 21.

[0051] In some embodiments, a limiting cavity 141 is formed on the side of the insertion part 14, and a connecting hole 25 is formed on the side of the connecting seat 2. A limiting rod is provided between the insertion part 14 and the connecting seat 2, and the limiting rod passes through the connecting hole 25 and the limiting cavity 141. When the insertion part 14 slides along the insertion cavity 21, different positions of the connecting hole 25 and the limiting cavity 141 correspond to each other. When the locking structure 1 slides relative to the connecting seat 2, the sliding position of the locking structure 1 is limited by the cooperation of the limiting rod and the limiting cavity 141.

[0052] In this embodiment, the sliding stroke of the locking structure 1 can be precisely limited by the cooperation between the limiting rod and the limiting cavity 141, effectively preventing the locking structure 1 from disengaging from the connecting seat 2 due to excessive movement during the sliding adjustment process, thus ensuring the safety and stability of the sliding adjustment. At the same time, the limiting structure is simple and compact, does not affect the overall assembly efficiency, and can provide a guiding effect when the locking structure 1 slides, further improving the smoothness and accuracy of the sliding adjustment.

[0053] In some embodiments, the clamp 11 is provided with at least one fitting part 13, the inner wall surface of the fitting part 13 is a friction surface 131, which can significantly increase the friction with the surface of the first workpiece, effectively prevent the clamp 11 from sliding or rotating relative to each other after fitting, and ensure the clamping stability of the first workpiece; at the same time, the friction surface 131 can disperse the contact pressure and avoid local stress concentration leading to damage to the workpiece surface.

[0054] In some embodiments, the clamp 11 is formed by wrapping around a plate from end to end; the clamp locking member 12 includes a ring 121 and a locking bolt 122, the head and tail ends of the clamp 11 overlap and are wrapped by the ring 121, the locking bolt 122 is disposed on the ring 121, and the locking bolt 122 cooperates with the inner wall of the ring 121 to lock the head and tail ends of the clamp 11.

[0055] In this embodiment, the clamp 11 formed by a single plate can be adapted to first workpieces of different diameters by adjusting the overlap length of its ends. Combined with the tightening operation of the locking bolt 122, opening, closing, and locking can be quickly completed without complex tools. By adjusting the overlap amount and the tightness of the locking bolt 122, it can adapt to first workpieces of different sizes and specifications, improving the versatility of the lock.

[0056] In some embodiments, the connecting seat 2 is provided with a groove 24 on the wall surface opposite to the locking structure 1, which can be adapted to the protrusion on the second workpiece, thereby enabling the connecting seat 2 and the second workpiece to be quickly positioned.

[0057] The above-mentioned locks are used in the following way when applied to stair handrails:

[0058] The connecting seat 2 is pre-positioned with the second workpiece (such as a railing bracket, wall embedded part, etc.) through the positioning part 22, and then the connecting seat 2 is fixed to the second workpiece with bolts through the mounting holes of the positioning part 22.

[0059] Operate the clamp locking part 12, loosen the locking bolt 122 on the ring 121, so that the overlapping part of the clamp 11 is loosened and the clamp 11 is in the open position, which makes it easy to install it onto the stair handrail (first workpiece).

[0060] Insert the clamp 11 into the designated position on the stair handrail, ensuring that the friction surface 131 of the inner wall of the fitting part 13 is in contact with the handrail surface. Adjust the overlap length of the clamp 11 to match the handrail diameter. Then tighten the locking bolt 122. By squeezing the overlapping part of the clamp 11 with the ring 121, the friction surface 131 is pressed tightly against the handrail surface, thus fixing the locking structure 1 on the stair handrail and preventing relative slippage.

[0061] Insert the plug part 14 of the locking structure 1 into the plug cavity 21 of the connector 2 to complete the mechanical connection between the locking structure 1 and the connector 2.

[0062] If the relative position of the stair handrail and the second workpiece needs to be adjusted, precise adjustment can be made through the adjustment structure 3: rotate the nut section 322 of the adjusting screw 32, and use the threaded engagement between the screw section 321 and the screw positioning seat 34 to convert the rotational motion into the linear motion of the screw positioning seat 34, which drives the locking structure 1 to slide along the insertion cavity 21 of the connecting seat 2; during the sliding process, the limiting rod moves in the limiting cavity 141, limiting the sliding stroke of the locking structure 1 and preventing it from disengaging from the connecting seat 2; after adjustment to the target position, the self-locking characteristic of the threaded drive keeps the locking structure 1 stably in position without the need for additional fixation.

[0063] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
