Technical Field
[0001] The utility model relates to the technical field of locks, and particularly relates to an improved structure of a lock box used in cooperation with a lock body. Background Art
[0002] At present, the locks on the market include a lock body installed on a door body and a lock box installed on a door frame. The lock tongue of the lock body extends out of the lock body and inserts into the lock slot of the lock box to achieve the purpose of locking the door. In order to facilitate the insertion of the lock tongue into the lock box, the lock slot of the lock box needs to be larger than the lock tongue. However, if the width of the lock slot is significantly larger than the width of the lock tongue, after the lock tongue is inserted into the door body, the lock tongue can move back and forth in the lock slot, and then the door body can move back and forth, resulting in abnormal noises.
[0003] An adjusting block is provided in the existing lock box. The adjusting block is arranged in parallel on one side of the lock slot, and the width of the lock slot is adjusted by moving the adjusting block. However, the adjusting block is adjusted level by level through a number of clamping positions, and the adjustment range is limited (for example, the adjustment distance at one time is 1 mm). It is easy to occur that when pushing one level, the lock tongue cannot be inserted, and when pulling out one level, the gap between the lock tongue and the lock slot is too large. Moreover, there are two installation methods for the adjusting block. One is to be hidden in the lock box. In this way, there is a step between the adjusting block and the front of the lock box, resulting in the lock tongue being inserted into the lock box but abutting against the adjusting block, and the lock tongue does not insert into the lock slot, so the due effect of locking the door cannot be achieved. The other is that the lock box is provided with a notch for the adjusting block to move in parallel. In this way, the adjusting block is exposed, and the adjusting block and the lock box need to be provided with another fixing structure to limit the adjusting block from detaching from the lock box, and the structure is more complex. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an improved structure of a lock box different from the existing adjustment method.
[0005] The purpose of the utility model is achieved as follows.
[0006] An improved structure of a lock box includes a lock box body. A lock slot for inserting a lock tongue is provided on the front of the lock box body. A rotating member, an adjusting device and an elastic member are provided on the side of the lock slot of the lock box body. The elastic member has a tendency to push the rotating member to rotate towards the side of the lock slot where it is located. The adjusting device makes the rotating member rotate from one side of the lock slot to the opposite side and overcomes the elastic force of the elastic member. The rotating member moves towards the inner cavity to reduce the width of the lock slot.
[0007] The utility model adjusts the width of the lock slot through the rotating member, and the adjustment is easier and smoother. The elastic member enables the rotating member to stop at any angle of the rotating member and can reset the rotating member. Compared with the existing lock box, the adjustment method is more flexible and reliable.
[0008] Furthermore, the adjusting device is an adjusting bolt and a screw hole. The screw hole is arranged on the lock box body on the side of the rotating part away from the lock slot. The adjusting bolt and the screw hole are threadedly connected. The head of the adjusting bolt is provided with an inclined extrusion surface. In the process of gradually screwing the adjusting bolt into the screw hole, the extrusion surface and the rotating part are abutted against each other, and the extrusion surface pushes the rotating part to rotate toward the side away from the adjusting bolt.
[0009] The regulating device has a simple structure and stable and reliable operation. It cooperates with the rotating parts to realize stepless regulation, and the regulating range is wider and more precise.
[0010] Furthermore, the tail of the adjusting bolt does not protrude from the front side of the lock box body.
[0011] The adjusting bolt does not affect the cooperation between the lock box and the lock body, thus avoiding obstruction of the door opening and closing.
[0012] Furthermore, a mounting groove is provided in the lock box body, which is located at one side of the lock groove and communicated with the lock groove. The bottom of the rotating member is pivotally connected to the bottom of the mounting groove, and the rotating member forms a side wall of the lock groove toward the lock groove.
[0013] The rotating parts are simple and easy to install.
[0014] Furthermore, a rotating shaft is formed at the bottom of the rotating member, and a rotating groove is provided at the bottom of the mounting groove. The rotating shaft rotates in the rotating groove to form the pivot connection, and the rotating member rotates with the rotating shaft.
[0015] The rotating structure of the rotating part is easy to implement and assemble, and the operation is stable and reliable.
[0016] Furthermore, a wear-resistant portion is provided on one side of the rotating member close to the adjusting device, and the rotating member abuts against the adjusting device via the wear-resistant portion.
[0017] The wear-resistant part prevents the adjusting device from damaging the rotating parts, reduces the failure rate of the lock box, and extends the service life of the rotating parts.
[0018] Furthermore, the rotating part is a plastic part, the wear-resistant part is made of metal material, and the rotating part and the wear-resistant part are processed into one piece.
[0019] The rotating parts and the wear-resistant parts are integrally processed to reduce the number of assembly parts and the assembly cost.
[0020] Furthermore, a limiting portion is provided at the bottom of the lock slot near one side of the mounting slot, one side of the limiting portion extends into the rotating slot, the limiting portion and the rotating member abut against each other to prevent the rotating member from continuing to rotate into the lock slot, and the limiting portion limits the rotating shaft from leaving the rotating slot opening.
[0021] The limiting part prevents the elastic member from failing due to excessive rotation of the rotating member, and has the function of limiting the position of the rotating shaft.
[0022] Further, the elastic member is a torsion spring. The torsion spring is sleeved on the pivot connection between the rotating member and the bottom of the installation groove. One end of the torsion spring abuts against the bottom of the locking groove, and the other end of the torsion spring abuts against the rotating member. The elastic force of the torsion spring keeps the rotating member in contact with the adjusting device.
[0023] The elastic member has a low cost and is easy to install.
[0024] Further, the front surface of the rotating member is an arc surface, and the highest point of the arc surface is always flush with the front surface of the lock box body.
[0025] There is no step difference between the front surface of the rotating member and the front surface of the lock box body, ensuring that the lock tongue falls into the locking groove.
[0026] The present utility model adjusts the width of the locking groove through the rotating member, and the adjustment is easier and smoother. The elastic member enables the rotating member to stop at any angle of the rotating member and allows the rotating member to reset. Compared with the existing lock box, the adjustment method is more flexible and reliable. The adjusting device has a simple structure, stable and reliable operation, and realizes stepless adjustment in cooperation with the rotating member, with a wider and more accurate adjustment range. The rotation structure of the rotating member is easy to implement, convenient for assembly, and has stable and reliable operation. There is no step difference between the front surface of the rotating member and the front surface of the lock box body, ensuring that the lock tongue falls into the locking groove.

[0033] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0034] Embodiment 1, referring to Figure 1-6 As shown, an improved structure of a lock box includes a lock box body 1, a rotating member 2, an adjusting device 3, and an elastic member 4. In this embodiment, a magnet 10 is provided on the back surface of the lock box body 1 facing the locking groove 5. This improved structure of the lock box can be adapted to a magnetic lock for use.
[0035] The front of the lock box body 1 is provided with a lock slot 5 for inserting a lock tongue. The lock box body 1 is provided with a mounting slot 6 on one side of the lock slot 5, the mounting slot 6 is communicated with the lock slot 5, and a rotation slot 7 is provided on the bottom surface of the mounting slot 6 close to the lock slot 5. A limiting portion 8 is provided on the bottom of the lock slot 5 close to the mounting slot 6, and one side of the limiting portion 8 extends into the rotation slot 7. The lock box body 1 is made of plastic material, and the opening formed between the limiting portion 8 and the rotation slot 7 has a certain elastic deformation.
[0036] In this embodiment, the lock box body 1 is provided with a boss 11, which extends from the side of the mounting groove 6 away from the lock groove 5 and is suspended on the mounting groove 6, and the front of the boss 11 is flush with the front of the lock box body 1. A stopper 12 is also extended above the corresponding mounting groove 6 of the lock box body 1, and the front of the stopper 12 is flush with the front of the lock box body 1. The stopper 12 and the boss 11 are staggered. Preferably, there are two stoppers 12, and the boss 11 is placed between the stoppers 12, and the two stoppers 12 are arranged symmetrically up and down.
[0037] A rotating shaft 21 is formed at the bottom of the rotating member 2, and a wear-resistant portion 9 is provided on the side of the rotating member 2 close to the adjusting device 3, and the rotating member 2 abuts against the adjusting device 3 through the wear-resistant portion 9. Preferably, the rotating member 2 is a plastic member, and the wear-resistant portion 9 is made of metal material, and the rotating member 2 and the wear-resistant portion 9 are processed as one piece.
[0038] The front of the rotating member 2 is an arc surface 20. After the rotating member 2 is installed, the highest point of the arc surface 20 is always flush with the front of the lock box body 1. The front of the rotating member 2 is provided with a first clearance notch 22 corresponding to the boss 11, and the front of the rotating member 2 is provided with a second missing notch 23 corresponding to the stopper 12.
[0039] The rotating member 2 is obliquely inserted into the mounting groove 6 from the locking groove 5, and the rotating shaft 21 overcomes the resistance of the limiting portion 8 and is inserted into the rotating groove 7. The rotating shaft 21 rotates in the rotating groove 7 to form a pivot connection, and the rotating member 2 rotates with the rotating shaft 21. The side of the rotating member 2 facing the locking groove 5 forms a side wall of the locking groove 5. The limiting portion 8 limits the rotating shaft 21 from leaving the opening of the rotating groove 7.
[0040] The elastic member 4 has a tendency to push the rotating member 2 to rotate towards the side of the locking groove 5 where it is located. In this embodiment, the elastic member 4 is a torsion spring, and the torsion spring is sleeved on the pivot connection between the rotating member 2 and the bottom of the installation groove 6, that is, the torsion spring is sleeved on the rotating shaft 21. One end of the torsion spring abuts against the bottom of the locking groove 5, and the other end of the torsion spring abuts against the rotating member 2. The elastic force of the torsion spring keeps the rotating member 2 in contact with the adjusting device 3. The adjusting device 3 rotates the rotating member 2 from one side of the locking groove 5 to the opposite side and overcomes the elastic force of the elastic member 4. The rotating member 2 moves towards the inner cavity to reduce the width of the locking groove 5. Preferably, a first card slot 51 is provided on the bottom surface of the locking groove 5, and a second card slot 24 is provided on the side of the rotating member 2 facing the locking groove 5. One end of the torsion spring is clamped in the first card slot 51, and the other end of the torsion spring is clamped in the second card slot 24. The elastic force of the elastic member 4 keeps the stopper 12 inserted into the second missing notch 23. In this way, the rotating member 2 is not easily separated from the installation groove 6.
[0041] The adjusting device 3 is an adjusting bolt 31 and a threaded hole 32. The threaded hole 32 is provided on the lock box body 1 on the side of the rotating member 2 away from the locking groove 5, that is, the threaded hole 32 is provided on the boss 11. The adjusting bolt 31 is threadedly connected to the threaded hole 32. The head of the adjusting bolt 31 is provided with an inclined pressing surface 30. During the process of gradually screwing the adjusting bolt 31 into the threaded hole 32, the pressing surface 30 abuts against the wear-resistant part 9 of the rotating member 2, and the pressing surface 30 pushes the rotating member 2 to rotate away from the adjusting bolt 31, that is, the rotating member 2 rotates into the locking groove 5. Preferably, the tail of the adjusting bolt 31 does not protrude from the front surface of the lock box body 1.
[0042] Its working principle is as follows.
[0043] See Figure 4 and Figure 6 As shown, the adjusting bolt 31 is screwed outwards until the end face of its tail is flush with the front surface of the lock box body 1. At this time, the elastic member pushes the rotating member 2 to rotate away from the locking groove 5, and the width of the gap between the locking groove 5 and the rotating member 2 reaches the maximum width. In the use state, the maximum range of the adjusting bolt 31 screwed out depends on the gap between the door body and the front surface of the lock box body 1 when necessary.
[0044] As the adjusting bolt 31 is screwed inwards, the pressing surface 30 of the adjusting bolt 31 applies pressure to the wear-resistant part 9 of the rotating member 2, and then pushes the rotating member 2 to rotate into the locking groove 5. The width of the gap between the locking groove 5 and the rotating member 2 gradually decreases until the limiting part 8 abuts against the rotating member 2 to prevent the rotating member 2 from continuing to rotate into the locking groove 5. At this time, the width of the gap between the rotating member 2 and the locking groove 5 reaches the minimum width.
[0045] During this process, the elastic force of the elastic member and the thrust of the adjusting bolt 31 on the rotating member 2 are kept in balance, enabling the rotating member 2 to stop at any angle within the adjustment range, thus achieving stepless adjustment of the rotating member 2. The present utility model adjusts the width of the gap between the locking groove 5 and the rotating member 2 so that the width of the gap is adapted to the width of the locking tongue of the lock body. The arc surface 20 design of the rotating member 2 guides the locking tongue to insert into or leave the locking groove 5, and there will be no situation where... After the locking tongue inserts into the locking groove 5, there is basically no gap between the locking tongue and the locking groove 5 in the width direction, so that the locking tongue will not move back and forth within the locking groove 5, and thus the door body will not shake back and forth after being locked.
[0046] For example, when terms such as first and second are used in the present utility model, they do not represent any order, quantity or importance, but are only used for distinction.
[0047] For example, when terms such as a and an are used in the present utility model, they do not represent a limitation of quantity, but represent the existence of at least one of the mentioned objects.
[0048] For example, when terms indicating orientation or position such as one side, top, bottom, side, longitudinal, transverse, middle, center, outer, inner, horizontal, vertical, left, right, above, below, etc. are used in the present utility model, they mean to reflect the relative position rather than the absolute position. For example, the front of the lock box body 1 refers to the exposed surface after its installation, and the width direction of the locking groove 5 refers to the width direction of the door frame or the thickness direction of the door.
[0049] For example, when terms such as approximately, overall, approximate, similar, etc. are used in the present utility model, they are limiting terms used to indicate the existence of features but allowing a certain deviation. The amount of allowable deviation may vary depending on the specific background.
