Description

Technical Field

[0001] This utility model relates to the field of lock tongue structure technology, and more specifically, to a lock tongue fixing structure and lock body. Background Technology

[0002] A lock is a device typically installed at the opening and closing points of doors, windows, cabinets, etc., to prevent unauthorized opening. There are many types of locks, including padlocks, drawer locks, and spherical door locks. The lock body has many components, such as the bolt, which is the connecting link between the door and the door frame. As the part of the door lock system that directly undertakes the locking function, the stability and security of the bolt are particularly important.

[0003] According to patent authorization announcement number CN217681080U, a latch mechanism and its application in a lock body are used for locking a door leaf. The mechanism includes a latch box, a slanted latch, a push block, and a push block spring. The latch box has a latch cavity and a latch hole. The slanted latch includes a left end region and a right end region. The slanted latch, push block, and push block spring are arranged sequentially in the latch cavity. The lock body includes a lock housing and a latch mechanism housed within the lock housing. It also includes a door handle and a lock cylinder movably mounted on the lock housing and linked to the latch mechanism. The latch tail end is similar to existing technologies, still using an elastic element, a guide push block, and a guide rod to drive the latch's extension and retraction. A large gap exists between the latch and the lock body, resulting in low strength, making it easily damaged by force. Furthermore, the latch can be pushed back without using the door handle, making it vulnerable to theft. After prolonged use, it is prone to aging and malfunction.

[0004] Therefore, in summary, there is an urgent need to design a lock tongue fixing structure and lock body with good stability. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a lock tongue fixing structure and lock body with good stability.

[0006] A locking tongue fixing structure and lock body include a lock box, an oil reservoir, a push assembly, an oil inlet pipe, a transfer frame, a partition, a guide block, a sliding rod, a locking tongue, a mounting shell, and a handle. The lock box has an internal cavity, which is inverted T-shaped. An oil reservoir filled with hydraulic oil is located at the top of the cavity. A push assembly is located between the oil reservoir and the cavity, extending through both the front and rear sides of the lock box. An oil inlet pipe is located on the right side of the oil reservoir. A transfer frame is located on the right side of the cavity, connected to the other end of the oil inlet pipe. A guide block is located in the middle of the transfer frame. Two oil inlets are symmetrically arranged. A sliding rod is slidably installed between the left and right sides of the transfer frame, and the sliding rod also passes through the middle of the guide block. A partition is installed on the sliding rod, which is located on the right side of the transfer frame and the two are in sliding cooperation. A locking tongue is installed at the right end of the sliding rod, which passes through the right side of the lock box. An oil storage chamber is opened inside the lock box, which is located on the left side above the transfer frame and the two are connected. There are two mounting shells, which are fixedly installed on the two sides of the door body respectively. The front and rear ends of the push component pass through the mounting shells, and handles are installed at both the front and rear ends of the push component.

[0007] To further explain, the pushing component includes an elastic element, a piston, a connecting shaft, and a top block. An elastic element is provided at the top inner part of the oil reservoir, and a piston is provided at the bottom end of the elastic element. The piston and the oil reservoir are in a sliding engagement. A connecting shaft is rotatably installed through the cavity on the left side of the lock box. Both ends of the connecting shaft are connected to the handle. A top block is provided on the right side of the middle part of the connecting shaft, and the top block is in contact with the piston.

[0008] To further explain, it also includes a push block and a locking rod. The push block is inserted into the bottom right side of the lock box, and the locking rod is slidably installed on the right side of the lock box. The locking rod and the push block are in a pressing contact engagement.

[0009] To further explain, it also includes a locking block; the bottom of the lock box has a locking block that engages with the push block in a locking manner.

[0010] To further explain, the contact surface between the top block and the piston is arc-shaped, which is suitable for cooperating with the rotation of the connecting shaft to fit the piston and form a pushing operation.

[0011] To further explain, the space between the sliding rod and the transfer frame is at its minimum, which is suitable for creating a large pressure difference.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention controls the operation of the lock tongue by squeezing and pushing hydraulic oil, and forms a pressure difference in conjunction with the space operation between the oil storage frame and the transfer frame, thereby stabilizing the operation of the lock tongue and making the movement of the lock tongue more stable when it retracts and extends, thereby improving the stability and fixation between the lock tongue and the door frame.

[0013] 2. This utility model pushes the lever to the right by pushing the lever, thereby increasing the distance between the lever and the door frame. The lever is then fixed in position with the door frame, thus achieving a stable effect. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example: A latch fixing structure and lock body, such as Figures 1-4As shown, the device includes a lock box 1, an oil reservoir 102, a push assembly, an oil inlet pipe 106, a transfer frame 107, a partition 1071, a guide block 1072, a sliding rod 1073, a locking tongue 108, a mounting shell 2, and a handle 3. The lock box 1 has a transversely oriented cavity 101, which provides storage space for internal components. The cavity 101 is inverted T-shaped. An oil reservoir 102 is housed within the protruding portion at the top of the cavity 101. The oil reservoir 102 is filled with hydraulic oil, which is used to push the locking tongue 108. A push assembly is located between the oil reservoir 102 and the cavity 101, and the push assembly penetrates the lock box 1. The front and rear sides of the cavity 101 are connected to the hydraulic oil via the push assembly, which facilitates subsequent use. An oil inlet pipe 106 is connected to the right side of the oil reservoir 102. The oil inlet pipe 106 is L-shaped and is used to transport the hydraulic oil squeezed out from the oil reservoir 102. A transfer frame 107 is located on the right side inside the cavity 101. The transfer frame 107 is in close contact with the inner wall of the cavity 101. The right side of the transfer frame 107 is connected to the other end of the oil inlet pipe 106, forming a channel for hydraulic oil flow. A guide block 1072 is located in the middle of the transfer frame 107, and two symmetrical oil inlet holes are provided on the guide block 1072. The oil inlet hole allows hydraulic oil to be discharged, thereby creating a pressure difference inside the transfer frame 107. A sliding rod 1073 is slidably installed between the left and right sides of the transfer frame 107, and the sliding rod 1073 also passes through the middle of the guide block 1072. The space between the sliding rod 1073 and the transfer frame 107 is minimized, which is suitable for creating a larger pressure difference, thereby pushing the locking tongue 108 to move more stably. A partition 1071 is installed on the sliding rod 1073. The partition 1071 is located on the right side inside the transfer frame 107 and the two are in a sliding fit. The perimeter of the partition 1071 is in contact with the inner wall of the transfer frame 107. This forms a hydraulic oil storage space on the right side of the transfer frame 107. A locking tongue 108 is provided at the right end of the sliding rod 1073. The locking tongue 108 passes through the right side of the lock box 1, and an oil storage chamber 109 is provided inside the lock box 1. Initially, the oil storage chamber 109 is empty. The oil storage chamber 109 is located on the left side above the transfer frame 107 and the two are connected, which can form a space to push the hydraulic oil to flow. There are two mounting shells 2. The two mounting shells 2 are fixedly installed on the front and rear sides of the door body, and the front and rear ends of the pushing component pass through the mounting shells 2. The front and rear ends of the pushing component are provided with handles 3. The handles 3 are the starting parts for pushing this device.

[0022] like Figure 2 and Figure 3As shown, the pushing assembly includes an elastic element 1021, a piston 103, a connecting shaft 104, and a top block 105. The elastic element 1021, which is a spring, is fixedly installed at the center of the top of the oil reservoir 102. The bottom end of the elastic element 1021 is provided with the piston 103, which slides up and down with the oil reservoir 102. The connecting shaft 104 is rotatably installed through the cavity 101 on the left side of the lock box 1. Both the front and rear ends of the connecting shaft 104 are connected to the handle 3. The top block 105 is provided on the right side of the middle part of the connecting shaft 104. The top block 105 is in contact with the piston 103. The contact surface between the top block 105 and the piston 103 is arc-shaped, which is suitable for cooperating with the rotation of the connecting shaft 104 to fit the piston 103 and form a pushing operation.

[0023] like Figures 1-3 As shown, it also includes a push block 110 and a locking rod 112. The push block 110 is longitudinally inserted into the bottom right side of the lock box 1, and the locking rod 112 is slidably arranged on the right side of the lock box 1. The locking rod 112 has a three-bar body, and the locking rod 112 and the push block 110 are in a squeezing contact engagement, thereby pushing the locking rod 112 to fix it to the door frame, so as to achieve a stable effect.

[0024] like Figure 2 and Figure 3 As shown, it also includes a locking block 111. The bottom of the lock box 1 is provided with a locking block 111. The locking block 111 is protruding and engages with the push block 110 to fix the position of the push block 110.

[0025] First, the worker installs the lock box 1 inside the door, with the latch 108 positioned at the junction with the door frame. Simultaneously, the mounting housing 2 is installed on both sides of the door to match the lock box 1. The handle 3 and its components rotate with the corresponding mounting housing 2. When the lock needs to be used, the user twists the handle 3 downwards. As the handle 3 is turned downwards, the connecting shaft 104 rotates counterclockwise. The connected top block 105 also rotates synchronously with the connecting shaft 104. The top block 105 contacts the piston 103 above, and the pressure from the top block 105 pushes the piston 103 upwards, causing the elastic element 1021 to release. The piston 103 slides upward within the oil reservoir 102 due to deformation and compression. This compression causes the hydraulic oil within the reservoir 102 to be compressed, increasing the pressure within the space. The hydraulic oil inside the reservoir 102 flows towards the inlet pipe 106, and through the inlet pipe 106, it flows to the right side of the transfer frame 107. The hydraulic oil fills the right side of the transfer frame 107, increasing the pressure inside, which pushes the partition 1071 to slide to the left. This, in turn, causes the sliding rod 1073 to move to the left, and the locking tongue 108 moves to the left and retracts into the lock box 1. Due to compression, it is positioned to the left of the partition 1071. The hydraulic oil is pushed towards the guide block 1072, and then flows through the oil inlet on the guide block 1072 to the other side of the transfer frame 107. The hydraulic oil fills the transfer frame 107 on the left side of the guide block 1072. At the same time, the hydraulic oil is pressurized and flows upward to the oil reservoir 109, compressing the space in the oil reservoir 109. At the same time, there is still space in the oil reservoir 109, and the interior is in a state where air and hydraulic oil coexist. At this time, the latch 108 is disengaged from the door frame, and the door is open. When it is necessary to close the door, the handle 3 is released, so that the piston 103 is not compressed, that is, the oil reservoir 109 is not compressed and the hydraulic oil inside flows back into the transfer frame 107. The push plate 1071 and sliding rod 1073 are then slid to the right, and the hydraulic oil on the right side of the transfer frame 107 is pushed back into the oil inlet pipe 106, and the whole thing is returned to its original position. The lock tongue 108 then moves to the right to lock and fix the door frame position. Then, the push block 110 is pushed upward, so that the push block 110 slides upward in the lock box 1, while pressing the locking rod 112 and pushing the locking rod 112 to slide to the right. When the push block 110 and the locking block 111 are in contact, that is, when the push block 110 has moved to the end, the locking rod 112 is also fully inserted into the door frame, completing the fixing operation. The above are the overall usage steps of this lock body.

[0026] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. They only express the preferred implementation of this utility model and are described in a relatively specific and detailed manner, but they should not be construed as limiting the scope of this utility model patent.

[0027] It should be noted that, for those skilled in the art, various modifications, increases or decreases in quantity, improvements and substitutions can be made without departing from the concept of this utility model. Therefore, based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
