Description

Technical Field

[0001] The utility model relates to the technical field of key detection, in particular to a fixture structure used for key detection. Background Art

[0002] During the production of electronic products, jigs are required to ensure dimensional accuracy and quality of finished products. Jigs are a broad category of tools used in carpentry, ironwork, locksmithing, mechanics, electronic control, and other crafts, primarily to assist in controlling position or movement. Jigs can be categorized as process assembly jigs, project testing jigs, and circuit board testing jigs. Therefore, jig structures are essential for testing electronic product buttons.

[0003] Currently, when testing buttons on the market, it is necessary to use plasticine to fix them and then find the reference point and balance point. This method is complicated to operate and has low work efficiency. It also cannot better grasp the balance point, resulting in offset during testing and large dimensional deviation, which reduces the accuracy and measurability of the test measurement. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing jig is not convenient for balance detection, which causes detection deviation and reduces detection accuracy, and to propose a jig structure for key detection.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0013] Pressing rods, the pressing rods are fixed on the insertion rods, and the number of the pressing rods corresponds to the number of the insertion rods;

[0014] A spring is fixed between the two insertion rods.

[0015] Preferably, a clamping slot is provided on the inner side wall of the fixture body, and the clamping slot is clamped with the clamping block.

[0016] Preferably, a slot is provided inside the fixture body, the slot is communicated with the card slot, and the slot is plugged into the insertion rod.

[0017] Preferably, the inner diameter of the card slot is larger than the outer diameter of the card block, and the circular diameter of the slot is larger than the circular diameter of the insertion rod.

[0018] Preferably, a bottom surface of the flat placement platform is provided with a recessed groove for engaging with the support block.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The utility model is provided with a flat placement table at a right angle of 90 degrees. The product can be directly placed on it and kept in a horizontal state during measurement, so that the balance test can be performed directly during measurement without manual leveling and debugging, thereby improving the work efficiency of testing and inspection.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 4 A jig structure for key detection includes a jig body 1, a support block 2 is installed on the inner side wall of the jig body 1, and a flat placement table 4 is detachably installed above the support block 2;

[0030] A fixture structure for key detection also includes a disassembly part, which is used to assemble and disassemble the flat placement table 4.

[0031] Furthermore, the disassembly member includes a block 42 fixed to the bottom surface of the flat placement table 4, an annular groove 43 formed on the surface of the block 42, and a rod 45 slidably connected to the block 42. The rod 45 can slide linearly along a specific trajectory to enter or exit the slot 31, thereby locking or unlocking. Two rods 45 are symmetrically provided about the block 42, and the two rods 45 slide in the same direction. The sliding of the rods 45 is indirectly controlled by operating a pressing rod 44. The number of pressing rods 44 fixed to the rods 45 corresponds to the number of rods 45, ensuring that each rod 45 can be controlled independently or synchronously. The number of pressing rods 44 corresponds to the number of rods 45. A spring 46 is fixed between the two rods 45. The spring 46 provides a reset force. When the pressing rod 44 is released, the spring 46 pushes the rod 45 back to its initial position, ensuring that the structure remains locked in the absence of external force.

[0032] Furthermore, a clamping slot 3 is formed on the inner side wall of the fixture body 1 , and the clamping slot 3 is clamped with the clamping block 42 .

[0033] Furthermore, a slot 31 is formed inside the fixture body 1, which is connected to the card slot 3 and is plugged into the insertion rod 45. In the initial state, the two insertion rods 45 are retained in the slot 31 due to the action of the spring 46, thereby forming a stable connection between the placement table and the fixture body 1 and achieving locking.

[0034] Furthermore, the inner diameter of the card slot 3 is larger than the outer diameter of the card block 42, and the diameter of the slot 31 is larger than the diameter of the insertion rod 45. This design provides the necessary clearance so that the card block 42 will not encounter excessive resistance or friction when being inserted or removed from the card slot 3 and the insertion rod 45 when being inserted or removed.

[0035] Furthermore, a recessed groove 41 for engaging with the supporting block 2 is formed on the bottom surface of the flat placement platform 4 .

[0036] The functional principle of this utility model can be explained through the following operation modes:

[0037] When using the fixture for measurement and testing, a flat placement table 4 is set up. The flat placement table 4 adopts a 90-degree right-angle design. The electronic product to be measured is placed on the flat placement table 4 and can be directly in a horizontal state, so that the balance test can be performed directly during measurement without manual leveling and debugging, thereby improving the work efficiency of testing.

[0038] The flat placement table 4 is easy to wear out after long-term use, which will cause unevenness in some areas. Therefore, it needs to be replaced regularly. When replacing, both fingers move inward to press the two pressing rods 44 to slide in the annular groove 43. The two pressing rods 44 are forced to drive the corresponding insertion rods 45 to slide into the inside of the block 42 at the same time, squeezing the spring 46 during sliding. The spring 46 is forced to shrink. When the two insertion rods 45 are completely stuck in the block 42, the flat placement table 4 is pulled out to separate it from the support block 2, thereby completing the disassembly of the old flat placement table 4, and then the new flat placement table 4 is attached to the inner wall of the fixture body 1. At the same time, the concave part at the bottom of the new flat placement table 4 is pressed against the inner wall of the fixture body 1. The recessed groove 41 is engaged with the support block 2, and then the two insertion rods 45 are pressed to embed them into the block 42 and push the flat placement table 4, so that the block 42 on the end side is clamped in the slot 3 in the fixture body 1 and clamped. After clamping, the pressing rod 44 is released, and the spring 46 is reset by its own elastic performance after the pressing force is released, and the insertion rod 45 is reset and clamped into the slot 31 under the drive of the spring 46 to clamp and limit, so that the flat placement table 4 can be replaced quickly, avoiding the uneven surface of the flat placement table 4 after long-term use, which may cause deviations in subsequent tests, so that it is always in a flat state during measurement, thereby improving the accuracy of detection and measurement.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
