Description

Technical Field

[0001] This utility model relates to the technical field of security door locks, and in particular to a novel U-shaped glass door latch lock. Background Technology

[0002] Currently, the most widely used glass door latch is the U-lock, particularly suitable for frameless glass doors. This type of latch gets its name from the "U" shape of its bolt or lock body and is widely used in residential and commercial buildings. However, with prolonged use, the latch rod is prone to rusting due to environmental factors such as humidity and salt spray. This corrosion not only affects the mechanical strength of the latch rod but also reduces the assembly precision between it and the fixed lock body, thus affecting the normal use and security of the lock. More importantly, rust or corrosion increases the friction between the latch rod and the latch, increasing resistance and making it more difficult to open and close the glass door. Furthermore, long-term corrosion may also affect the security performance of the lock, increasing security risks associated with the glass door. Utility Model Content

[0003] This utility model solves the problems in related technologies and proposes a novel U-shaped glass door latch lock. By setting a lock sleeve on the outer periphery of the lock rod and fixing the lock sleeve to the lock rod through a locking mechanism, it is easy to protect the outer periphery of the lock rod through the lock sleeve, effectively avoiding the corrosion of the lock rod by the external environment.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a novel U-shaped glass door latch, including a latch, the latch including a U-shaped handle, a locking rod respectively fixedly disposed on both sides of the open end of the handle, a fixing lock for closing the locking rod, and a locking sleeve sleeved on the outside of the locking rod, and the locking sleeve having lock holes arranged on it to cooperate with the locking tongue of the fixing lock.

[0005] The handle and the lock rod are designed as an integral structure, and the upper end of the handle is covered with a plastic sleeve. The lock sleeve is fitted onto the lock rod, and the connection between the upper end of the lock sleeve and the lock rod is fixed by a limiting engagement structure. In this application, the lock hole structure on the existing lock rod is transferred to the lock sleeve, and the lock sleeve is fixed to the lock rod by the engagement structure. During use, the lock tongue of the lock and the lock hole on the lock sleeve cooperate to achieve locking. This can reduce the production difficulty of the lock rod and will not reduce the overall strength of the lock rod due to slotting. In addition, the lock sleeve is a replaceable structure that can be replaced.

[0006] As a preferred embodiment, the handheld part and the locking bar are configured as separate structures;

[0007] It also includes a locking sleeve fixedly connected to the hand-held part and disposed on the outer periphery of the locking rod, a locking sleeve sleeved on the outer periphery of the locking rod and connected to the locking sleeve, and a locking mechanism disposed between the locking sleeve and the locking sleeve;

[0008] The locking mechanism includes locking springs evenly distributed at one end of the locking sleeve relative to the locking sleeve, a locking part disposed at the end of the locking springs away from the locking sleeve, a tapered hole disposed on one side of the locking part, a locking rod connected to the tapered hole, a fixing bushing disposed on the locking sleeve for fixing the locking rod, and a connecting mechanism disposed between the locking rod and the fixing bushing. The inner wall of the locking sleeve decreases sequentially in the direction away from the locking sleeve, and the inner wall of the locking sleeve is set as a smooth arc surface.

[0009] By adopting the above technical solution, locking springs are evenly distributed at one end of the lock sleeve to provide elastic force when the lock sleeve moves; the locking part is located at the other end of the locking springs, and together with the locking springs, it realizes the locking and unlocking functions of the lock sleeve; a tapered hole is located on one side of the locking part to cooperate with the locking rod and guide the insertion and removal of the locking rod; the locking rod is connected to the tapered hole and can move along the inner wall of the lock sleeve under the guidance of the tapered hole, while being fixed to the fixed bushing through the connecting mechanism to ensure the stability of the locking rod's position; the fixed bushing is located on the lock sleeve to fix the locking rod; the inner wall of the lock sleeve is designed as a smooth arc surface and gradually narrows along its length, which facilitates the compression of the outer periphery of the locking springs when the lock sleeve moves, thereby realizing the locking and releasing of the lock sleeve.

[0010] As a preferred embodiment, the locking spring is composed of several elastic steel sheets with the center of the lock sleeve as the center point, and the outer diameter of each elastic steel sheet increases sequentially in the direction away from the lock sleeve.

[0011] By adopting the above technical solution, the inner wall of the locking sleeve is designed as a smooth arc surface, which gradually narrows along its length, making it easier to squeeze the outer periphery of the locking spring when the locking sleeve moves, thereby achieving locking and releasing of the locking sleeve.

[0012] As a preferred embodiment, the end of the locking rod relative to the tapered hole is configured as a conical structure, and the outer periphery of the conical structure is configured as a smooth arc surface.

[0013] By adopting the above technical solution, the locking rod provides precise alignment and distance adjustment through the conical structure; the locking spring is fixed by contracting and making tight contact with the outer periphery of the locking rod; the conical hole of the locking part ensures that the locking rod can be accurately inserted and the distance can be adjusted; the locking sleeve applies force to the locking spring through its conical inner wall, causing it to contract and fix the locking sleeve and the locking rod.

[0014] As a preferred embodiment, the outer peripheral fixed bushing is fixedly connected to the locking sleeve, and a sealing gasket is provided at the connection between the fixed bushing and the locking sleeve.

[0015] By adopting the above technical solution, the main function of the fixed bushing is to provide a stable support for the locking sleeve, preventing relative rotation or sliding of the locking sleeve at the connection point, thereby ensuring the stability and reliability of the entire device. The locking sleeve is responsible for tightly fastening the locking rod, realizing the function of fixing or locking the target object. The sealing gasket is installed at the connection point between the fixed bushing and the locking sleeve, effectively isolating external moisture and water vapor, preventing moisture from penetrating into the locking sleeve through the connection gap, and thus avoiding corrosion of the locking rod.

[0016] As a preferred embodiment, the connecting mechanism includes an adjusting thread disposed on the inner wall of the fixed bushing and a connecting thread disposed on the outer periphery of the locking rod.

[0017] By adopting the above technical solution, the adjusting thread on the inner wall of the fixed bushing and the connecting thread on the outer circumference of the locking rod respectively provide the function of threaded connection, enabling the locking rod to be precisely adjusted in axial position within the fixed bushing. When the locking rod is rotated, the connecting thread on the locking rod interacts with the adjusting thread inside the fixed bushing, thereby achieving relative rotation between the locking rod and the fixed bushing. This structure not only facilitates the adjustment of the connection position between the locking rod and the tapered hole, but also maintains the stability of the connection through precise threaded engagement.

[0018] As a preferred embodiment, the locking rod is configured as an embedded type, and the end of the locking rod away from the tapered hole is configured as an internal hexagonal structure.

[0019] By adopting the above technical solution, the end of the locking rod away from the tapered hole is designed with an internal hexagonal structure, which makes it easy for users to adjust it with a wrench, thereby achieving the operation of tightening or loosening.

[0020] As a preferred embodiment, the device further includes a tension spring disposed at one end of the locking sleeve relative to the locking sleeve, one end of the tension spring being fixedly connected to or snapped into the locking sleeve, and the other end of the tension spring being fixedly connected to the inner wall of the locking sleeve.

In addition, the lock sleeve 22 is a replaceable structure that can be replaced.)

[0042] Example 2

[0043] Please refer to the figure for details. Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model also provides a novel U-shaped glass door latch, including a latch 1. The latch 1 includes a U-shaped handle 11, a locking rod 12 fixedly disposed on both sides of the open end of the handle 11, a fixing lock 100 for closing the locking rod 12, and a locking sleeve 2 sleeved on the outside of the locking rod 12, with locking holes 23 arranged on the locking sleeve 2 to cooperate with the locking tongue of the fixing lock 100. The handle 11 and the locking rod 12 are configured as separate structures. It also includes a locking sleeve 111 fixedly connected to the handle 11 and disposed on the outer periphery of the locking rod 12, a locking sleeve 2 sleeved on the outer periphery of the locking rod 12 and connected to the locking sleeve 111, and a locking mechanism disposed between the locking sleeve 2 and the locking sleeve 111.

[0044] Please refer to the figure for details. Figure 3 , Figure 4 , Figure 5 and Figure 6 The locking mechanism includes locking spring pieces 21 evenly distributed at one end of the locking sleeve 2 opposite to the locking sleeve 111, a locking part 22 disposed at the end of the locking spring pieces 21 away from the locking sleeve 2, a tapered hole 31 disposed on one side of the locking part 22, a locking rod 32 connected to the tapered hole 31, a fixing bushing 321 disposed on the locking sleeve 111 for fixing the locking rod 32, and a connecting mechanism disposed between the locking rod 32 and the fixing bushing 321. The inner wall of the locking sleeve 111 decreases sequentially in the direction away from the sleeve, and the inner wall of the locking sleeve 111 is set as a smooth arc surface. The locking spring pieces 21 are evenly distributed at one end of the locking sleeve 2 to provide elastic force when the locking sleeve 2 moves. The locking part 22 is disposed at the end of the locking spring pieces 21. At the other end of 21, together with the locking spring 21, the locking and unlocking functions of the lock sleeve 2 are realized; the tapered hole 31 is provided on one side of the locking part 22 and is used to cooperate with the locking rod 32 to guide the insertion and removal of the locking rod 32; the locking rod 32 is connected to the tapered hole 31 and can move along the inner wall of the locking sleeve 111 under the guidance of the tapered hole 31, and is fixed to the fixed bushing 321 through the connecting mechanism to ensure the stability of the locking rod 32; the fixed bushing 321 is provided on the locking sleeve 111 and is used to fix the locking rod; the inner wall of the locking sleeve 111 is designed as a smooth arc surface and gradually narrows in its length direction, which facilitates the compression of the outer periphery of the locking spring 21 when the lock sleeve 2 moves, thereby realizing the locking and releasing of the lock sleeve 2. In terms of working principle, through the cooperation of locking spring 21 and locking part 22, and the guidance of locking rod 32 in tapered hole 31, locking sleeve 111 locks or releases locking sleeve 2 by squeezing locking spring 21.

[0045] Please refer to details. Figure 3 , Figure 4 and Figure 6The locking spring 21 is composed of several elastic steel sheets with the center of the locking sleeve 2 as the center point, and the outer diameter of each elastic steel sheet increases sequentially in the direction away from the locking sleeve 2. The inner wall of the locking sleeve 111 is designed as a smooth arc surface and gradually narrows in its length direction, which facilitates the compression of the outer periphery of the locking spring 21 when the locking sleeve 2 moves, thereby realizing the locking and releasing of the locking sleeve 2.

[0046] Please refer to details. Figure 4 and Figure 5 The locking rod 32 has a conical structure at one end relative to the conical hole 31, and the outer circumference of the conical structure is a smooth arc surface. The locking rod 32 provides precise alignment and distance adjustment through the conical structure. The locking spring 21 is fixed by contracting and making tight contact with the outer circumference of the locking rod 12. The conical hole 31 of the locking part 22 ensures that the locking rod 32 can be accurately inserted and the distance can be adjusted. The locking sleeve 111 applies force to the locking spring 21 through its conical inner wall, causing it to contract and fix the lock 100 sleeve and the locking rod 12. The working principle is: by adjusting the distance between the locking rod 32 and the locking part 22, the locking sleeve 2 can move up and down within the locking sleeve 111. When the locking sleeve 2 is in the correct position, the locking spring 21 contracts under the action of the inner wall of the locking sleeve 111 and contacts the locking rod 12, thereby completing the fixation.

[0047] Please refer to details. Figure 1 and Figure 3 The outer periphery 321 of the fixed bushing is fixedly connected to the locking sleeve 111. A sealing gasket is provided at the connection between the fixed bushing 321 and the locking sleeve 111. The main function of the fixed bushing 321 is to provide stable support for the locking sleeve 111, preventing relative rotation or sliding of the locking sleeve 111 at the connection point, thereby ensuring the stability and reliability of the entire device. The locking sleeve 111 is responsible for tightly fastening the locking rod 12, realizing the function of fixing or locking the target object. The sealing gasket is installed at the connection between the fixed bushing 321 and the locking sleeve 111, effectively isolating external moisture and water vapor, preventing moisture from penetrating into the interior of the locking sleeve 111 through the connection gap, and thus avoiding corrosion of the locking rod 12.

[0048] Please refer to details. Figure 3The connecting mechanism includes an adjusting thread on the inner wall of the fixed bushing 321 and a connecting thread on the outer circumference of the locking rod 32. The adjusting thread on the inner wall of the fixed bushing 321 and the connecting thread on the outer circumference of the locking rod 32 provide threaded connection, allowing the locking rod 32 to be precisely adjusted axially within the fixed bushing 321. When the locking rod 32 is rotated, the connecting thread on the locking rod 32 interacts with the adjusting thread inside the fixed bushing 321, thereby achieving relative rotation between the locking rod 32 and the fixed bushing 321. This structure not only facilitates adjustment of the connection position between the locking rod 32 and the tapered hole 31 but also maintains connection stability through precise threaded engagement. The overall working principle is that by tightening or loosening the locking rod 32, its relative position with the fixed bushing 321 can be adjusted, thus achieving different connection states with the tapered hole 31.

[0049] Please refer to details. Figure 4 The locking rod 32 is set as an embedded type, and the end of the locking rod 32 away from the tapered hole 31 is set as an internal hexagon structure. The design of the end of the locking rod 32 away from the tapered hole 31 as an internal hexagon structure makes it easy for the user to adjust it with a wrench, thereby achieving the operation of tightening or loosening.

[0050] Please refer to details. Figure 3 and Figure 4 To ensure the stability of the connection between the locking sleeve 2 and the locking sleeve 111, a tension spring 33 is also provided at one end of the locking sleeve 2 relative to the locking sleeve 111. One end of the tension spring 33 is fixedly connected to or snapped into the locking sleeve 2, and the other end of the tension spring 33 is fixedly connected to the inner wall of the locking sleeve 111. The tension spring 33 is provided at one end of the locking sleeve 2 relative to the locking sleeve 111, with one end fixedly connected to or snapped into the locking sleeve 2 and the other end fixedly connected to the inner wall of the locking sleeve 111. This not only achieves initial fixation but also provides the necessary tension, making the connection between the locking sleeve 2 and the locking sleeve 111 more stable.

[0051] In this embodiment, by tightening or loosening the locking rod 32, its relative position to the fixed bushing 321 can be adjusted, thereby achieving different connection states with the tapered hole 31. The tapered hole 31 is located on one side of the locking part 22 and is used to cooperate with the locking rod 32, guiding the insertion and removal of the locking rod 32. The locking rod 32 is connected to the tapered hole 31 and can move along the inner wall of the locking sleeve 111 under the guidance of the tapered hole 31. At the same time, it is fixed to the fixed bushing 321 through the connecting mechanism to ensure the stability of the locking rod 32's position. The fixed bushing 321 is located on the locking part 22. The locking sleeve 111 is used to fix the locking rod of the locking 100. The inner wall of the locking sleeve 111 is designed as a smooth arc surface and gradually narrows along its length, which facilitates the compression of the outer periphery of the locking spring 21 when the locking sleeve 2 moves, thereby achieving the locking and releasing of the locking sleeve 2. The tension spring 33 is set at one end of the locking sleeve 2 relative to the locking sleeve 111. One end of the spring is fixedly connected or snapped to the locking sleeve 2, and the other end is fixedly connected to the inner wall of the locking sleeve 111. This can achieve initial fixation and provide the necessary tension, making the connection between the locking sleeve 2 and the locking sleeve 111 more stable.

[0052] When in use, the locking rod 12 with the locking sleeve passes through the lock handle of the glass door, and the locking rod 12 is closed by the fixed lock 100 to achieve the purpose of locking the glass door.

[0053] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
