Technical Field
[0001] The utility model relates to the technical field of shielding equipment, in particular to a lock buckle with adjustable locking height and a shielding darkroom. Background Art
[0002] A shielded anechoic chamber is an instrument used in electronics and communications technology. Specifically, it provides high-precision automated control of various components. The chamber consists of a test chamber body, a test turntable, and a test antenna array. The turntable and antenna array within the chamber can be remotely controlled via software commands, creating a diverse, high-precision OTA environment that closely resembles the DUT's real-world use cases.
[0003] In the related technology, in the current various wireless signal tests, the shielding isolation varies with the test environment and the required simulation scenarios. The door opening and closing needs to be configured with corresponding conductive materials around the door panel according to the different shielding isolation. Since the thickness of each conductive material is different, errors may occur when the door is closed. Therefore, there are many types of lock models. At the same time, because the box material is mostly made of sheet metal, the bending deformation is large, errors may occur, resulting in the door not being closed tightly, thereby causing signal leakage during the test and affecting the test accuracy.
[0004] Therefore, the existing technology needs to be improved. Utility Model Content
[0005] In order to remedy the deficiencies of the prior art, the present application proposes a lock with adjustable locking height and a shielded darkroom.
[0006] In the first aspect, a lock buckle with adjustable locking height adopts the following technical solution:
[0007] A lock buckle with adjustable locking height comprises a locking seat, an adjusting block, a locking rod and a fixing member, the locking seat being provided with a sliding groove for the adjusting block to slide, one end of the adjusting block being used to extend from the sliding groove, the part of the adjusting block extending from the sliding groove being provided with a placement groove for an external lock tongue to be placed, the locking rod being arranged on opposite side walls of the placement groove, the locking rod being used to block the lock tongue in the placement groove; the fixing member being arranged on the locking seat, the fixing member being connected to the adjusting block, and the fixing member being used to stop the adjusting block at a predetermined position of the sliding groove.
[0008] Preferably, the fixing member includes a fixing screw and a support spring, the fixing screw is arranged at the bottom of the placement slot, the rod of the fixing screw passes through the adjustment block and is threadedly connected to the bottom of the slide slot, the support spring is arranged at the bottom of the slide slot, and the support spring is connected to the adjustment block so that the adjustment block has a tendency to move away from the bottom of the slide slot.
[0009] Preferably, both ends of the locking rod are rotatably connected to the opposite side walls of the placement slot.
[0010] Preferably, the rod thread of the fixing screw is provided with a fixing nut, and the fixing nut is used to tightly abut against the bottom of the sliding groove.
[0011] Preferably, the side wall of the slide groove is provided with a limiting groove, the length direction of the limiting groove is toward the slide groove opening, and is connected with the slide groove opening; the side wall of the adjustment block is provided with a limiting block inserted into the limiting groove, and the side wall of the limiting block slides and abuts against the side wall of the limiting groove.
[0012] Preferably, a guide screw is further provided on the locking seat, and the rod of the guide screw penetrates into the slide groove from the bottom of the slide groove, and the rod of the guide screw is used for the support spring to be sleeved.
[0013] In a second aspect, the present invention further provides a shielding box adopting the following technical solution:
[0014] A shielded darkroom comprises a box body, a lock buckle and a lock tongue. The lock buckle and the lock tongue are both arranged on the box body, and the lock tongue is used to be clamped into the placement through groove.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] 1. During signal testing, different conductive materials are used according to the different needs of the objects under test. Since the thickness of the conductive materials may vary, the support spring can be compressed downward to allow the adjustment block to slide to different positions in the slide slot. Then, the fixing screw is threadedly connected to the locking seat by rotating the fixing screw to fix the adjustment block in the predetermined position in the slide slot. At this time, the locking rod can be at different heights, and locking at different heights can be completed. This design method allows the adjustment block to stay at different heights through the fixing parts, which can meet the needs of different conductive materials. Therefore, the standardization of the shielded darkroom lock is achieved, thereby reducing the cost of signal testing. At the same time, it can also avoid the problem of poor fit between the door panel and the box body caused by errors in the production process of the shielded darkroom, and avoid signal leakage in the shielded darkroom during the test, which helps to ensure the accuracy of the test data.
[0017] 2. Due to the setting of the fixing nut, the door of the shielded darkroom needs to be opened or closed frequently, and due to vibration, the threaded connection between the fixing screw and the locking seat will become loose. Therefore, after the adjustment block is fixed at a certain height, the fixing nut is turned downward to make the fixing nut abut against the bottom of the chute. This will generate a predetermined pressure between the fixing nut and the bottom of the chute to prevent the adjustment block from shaking and make the connection between the fixing bolt and the locking seat more stable.
[0018] 3. Due to the setting of the guide screw, since the support spring is sleeved on the rod of the guide screw, the guide screw can provide a guiding effect to the support spring when the support spring is compressed and reset, thereby avoiding the failure of the support spring caused by deviation. At the same time, when the adjustment block needs to be at the bottom of the slide groove, the guide screw can be connected to the locking seat through a thread to move the rod of the guide screw downward to form an avoidance, so as not to block the adjustment block.

[0025] The embodiment of the present application discloses a lock buckle with adjustable locking height. Figures 1 to 3 The lock comprises a locking seat 1, an adjusting block 2, a locking rod 3 and a fixing member 4. Specifically, the lower end surface of the locking seat 1 is used to be fixedly connected to the shielding darkroom, and a slide groove 11 is provided on the upper side surface of the locking seat 1, that is, the slide groove 11 notch is provided on the upper end surface of the locking seat 1, and the length direction of the slide groove 11 extends toward the lower end surface of the locking seat 1, and the lower end of the adjusting block 2 is slidably provided in the slide groove 11, and the upper end of the adjusting block 2 is used to extend out of the slide groove 11. A placement slot 21 is provided on the part where the adjusting block 2 extends out of the slide groove 11. The notch of the placement slot 21 is located on the upper end surface of the adjusting block 2, and the two sides of the placement slot 21 are opened so that the adjusting block 2 looks like a U-shaped state as a whole. In other embodiments, the placement slot 21 can be opened on only one side, and the placement slot 21 is used for placing the external lock tongue 8. The locking rod 3 is provided on the opposite side walls of the placement slot 21. The locking rod 3 is cylindrical, and the length direction of the locking rod 3 is parallel to the placement slot The opening direction of the placement slot 21 is set vertically, and the locking rod 3 is used to block the lock tongue 8 placed in the placement slot 21, which can prevent the lock tongue 8 from moving out of the placement slot 21; the fixing member 4 is set on the locking seat 1, and the fixing member 4 is connected to the adjusting block 2. The fixing member 4 is used to fix the adjusting block 2 at a predetermined position in the slide slot 11. Therefore, according to different test conditions, the adjusting block 2 is slid to make the adjusting block 2 be in a predetermined position in the slide slot 11, and then the adjusting block 2 is fixed by the fixing member 4, so that the locking rod 3 can be in different height positions, that is, different heights of locking can be completed, which can meet the test conditions of different conductive materials, thereby realizing the standardization of the shielded darkroom lock, and at the same time, it can also meet the problem of poor fit between the door panel and the box body caused by errors generated in the production process of the shielded darkroom, thereby not only reducing the signal test cost, but also ensuring the accuracy of the test data.
[0026] Reference Figure 1 and Figure 2The fixing member 4 includes a fixing screw 41 and a support spring 42. The structure of the fixing screw 41 is a prior art and will not be described in detail in this embodiment. The fixing screw 41 is arranged in the placement slot 21. The rod of the fixing screw 41 will go downward to pass through the bottom of the placement slot 21, and the rod of the fixing screw 41 is threadedly connected to the bottom of the slide slot 11. In this embodiment, the head of the fixing screw 41 is embedded in the bottom of the placement slot 21 to avoid affecting the external lock tongue 8; the support spring 42 is arranged in the slide slot 11, and the two ends of the support spring 42 are respectively connected to the bottom of the slide slot 11 to prevent the external lock tongue 8 from being affected. It is fixedly connected to the lower end face of the adjusting block 2. The structure of the support spring 42 is a compression spring. The support spring 42 has elastic potential energy that causes the adjusting block 2 to move in the direction away from the bottom of the slide groove 11. Two support springs 42 are provided, and the two support springs 42 are symmetrically connected to the adjusting block 2. Therefore, when it is necessary to adjust the height of the adjusting block 2, the adjusting block 2 is first pressed downward to compress the support spring 42 so that the adjusting block 2 is in a predetermined position. Then, the fixing screw 41 is threadedly connected to the bottom of the slide groove 11 to fix the adjusting block 2 in the predetermined position, thereby realizing locking of different heights of the lock.
[0027] Since the lock buckle vibrates when the door is frequently opened and closed during use, in order to ensure that the adjusting block 2 is stably in the predetermined position, a fixing nut 5 is provided on the rod of the fixing screw 41, and the fixing nut 5 is threadedly connected to the rod of the fixing screw 41. After the fixing screw 41 is threadedly connected to the bottom of the slide groove 11, the fixing nut 5 is rotated to the bottom of the slide groove 11 and abutted against the bottom of the slide groove 11 to form a connection with the bottom of the slide groove 11 with a predetermined strength, so that the shaking of the adjusting block 2 can be avoided as much as possible. At the same time, the relative position of the slide groove 11 is A limiting groove 12 is provided on both side walls, and the length direction of the limiting groove 12 extends along the sliding direction of the adjusting block 2, and the limiting groove 12 is connected with the notch of the sliding groove 11. A limiting block 22 is provided on the two side walls corresponding to the limiting groove 12 on the outer side wall of the adjusting block 2. The shape of the limiting block 22 is adapted to the limiting groove 12. The limiting block 22 is used to be inserted into the limiting groove 12, and the side wall of the limiting block 22 slides and abuts against the side wall of the limiting groove 12. The adjusting block 2 can also be restricted by the side wall of the limiting groove 12 to prevent shaking back and forth and left and right, thereby further improving the stability of the adjusting block 2 when in use.
[0028] In this embodiment, in order to improve the service life of the support spring 42, a guide screw 6 is provided on the locking seat 1. The guide screw 6 is provided at the bottom of the locking seat 1, and the rod of the guide screw 6 is inserted into the bottom of the slide groove 11. The support spring 42 is sleeved on the rod of the guide screw 6, and the head of the guide screw 6 is embedded in the locking seat 1. During the sliding process of the adjustment block 2, the rod of the guide screw 6 can guide the support spring 42, and can try to avoid the phenomenon that the support spring 42 is offset and fails during compression or resetting. At the same time, due to the setting of the guide screw 6, when the adjustment block 2 needs to slide to the bottom of the slide groove 11, the guide screw 6 can be screwed down to avoid the adjustment block 2, and the guidance of the support spring 42 can be achieved without affecting the adjustment block 2.
[0029] In addition, in this embodiment, in order to facilitate the locking of the external lock tongue 8, the locking rod 3 is set to be rotatable, that is, the two ends of the locking rod 3 are rotatably connected to the opposite side walls of the placement slot 21 through bearings. When the external lock tongue 8 is locked in the placement slot 21, the lock tongue 8 will abut against the locking rod 3. By rotating the locking rod 3, the lock can be taken in and out more conveniently.
[0030] At the same time, in this embodiment, in order to facilitate the rotation of the fixing screw 41 and the fixing nut 5, a notch 13 is opened on the side wall of the slide groove 11 to facilitate the fixing of the adjustment block 2 by the fixing screw 41 and the fixing nut 5, which is convenient for user operation.
[0031] The implementation principle of a lock with adjustable locking height in an embodiment of the present application is as follows: when conducting a signal test, according to actual conditions, the adjustment block 2 is pressed down to a predetermined height, and then the fixing screw 41 and the fixing nut 5 are tightened to fix the adjustment block 2 in a predetermined position, which can meet the needs of different conductive materials, thereby achieving standardization of the lock of the shielded darkroom and reducing the cost of signal testing. At the same time, it can also avoid the problem of poor fit between the door panel and the box body caused by errors generated during the production process of the shielded darkroom, and can avoid signal leakage during the test of the shielded darkroom, thereby helping to ensure the accuracy of the test data.
[0032] The present application also discloses a shielded darkroom, comprising a box body 7, a lock buckle and a lock tongue 8. The lock buckle and the lock tongue 8 are both arranged on the box body 7. The lock tongue 8 is used to be clamped in the placement groove 21 of the lock buckle, and the unlocking and locking are achieved by the locking rod 3. The shielded darkroom of this embodiment also has the above-mentioned beneficial effects, which will not be repeated here.
[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
