[0033] like Figure 1As shown, three dimensions of the internal parts of the lock, such as the lock core 1, are known. For example, a is the distance between two adjacent blades 11, c is the distance between an end face of the lock core 1 located inside the lock (hereinafter referred to as the first end face 12) and the first blade 11, and b is the distance between an end face of the lock core 1 exposed outside the lock (hereinafter referred to as the second end face 13) and the first end face 12 of the lock core 1.

[0034] The present invention discloses a device for accurately locating the position of internal parts of a lock, which is used for detecting each blade 11 arranged in an array on a lock core 1 inside the lock, and comprises a fixing seat 2, a dial plate 3, a detection member 4 and a bracket 5.

[0035] The scale plate 3 is arranged on one side of the fixing base 2 , and a plurality of scale grooves 31 are arranged in an array inside the scale plate 3 .

[0036] Optionally, in this embodiment, the fixing base 2 is a square structure. The dial 3 is fixed to one side of the fixing base 2 by screws, bolts, rivets or welding. Optionally, in this embodiment, the dial 3 is detachably connected to the fixing base 2.

[0037] Optionally, in one embodiment, the dial 3 is disposed on one side of the fixing base 2 .

[0038] Specifically, in this embodiment, the inner side of the dial 3 is a side of the dial 3 that is opposite to a side of the dial 3 that is exposed from the fixing base 2 .

[0039] The detection member 4 is movably arranged in the fixing seat 2, and both ends of the detection member 4 extend out of the fixing seat 2. Specifically, the fixing seat 2 is provided with a through hole 22 arranged along the length direction of the detection member 4, and the detection member 4 is arranged in the through hole 22 and can slide with the hole wall of the through hole 22.

[0040] Optionally, in this embodiment, the fixing base 2 includes two half structures, and the two half structures are fixed together by common means such as screws, bolts, rivets or welding.

[0041] An elastic component 6 is disposed in the detection member 4 . A portion of the elastic component 6 protrudes from the surface of the detection member 4 and can be engaged with the scale groove 31 .

[0042] Optionally, the elastic component 6 includes an elastic member 61 and a steel ball 62, the elastic member 61 is accommodated in the detection member 4, and the steel ball 62 is arranged at one end of the elastic member 61 facing the scale plate 3. The elastic member 61 may be a spring, one end of the spring along the axial direction points to the scale plate 3, and the steel ball 62 is arranged at one end of the spring pointing to the scale plate 3. Preferably, the diameter of the elastic member 61, such as the spring, at one end where the steel ball 62 is arranged is reduced to wrap the steel ball 62 inside to prevent the steel ball 62 from running out, and the end of the elastic member 61 away from the steel ball 62 is fixed in the detection member 4 by a screw.

[0043] The steel ball 62 partially protrudes from the spring and the surface of the detection member 4. When the detection member 4 is sliding, when the steel ball 62 contacts a position on the scale plate 3 that is not the scale groove 31, the detection member 4 can slide smoothly. When the steel ball 62 enters the scale groove 31, it will be stuck in the scale groove 31. At this time, the operator can feel an obvious pause. Therefore, during the sliding process, the pause can be used to determine that the detection member 4 has slid into a certain scale groove 31. Although it cannot be determined whether it has reached the specified blade 11, it can be determined which blade 11 has been reached by measuring the length of the detection member 4. Assuming that the detection member 4 has reached the specified blade 11, in order to detect the specific situation at a certain position on the blade 11, a sensor 7 is provided at the part of the detection member 4 that extends into the interior of the lock (it can also be said that the end of the detection member 4). After the detection member 4 reaches the position to be inspected, the sensor 7 can detect the situation of the blade 11.

[0044] An opening 21 is provided on one side of the fixing base 2 , and the outer edge of the scale plate 3 is fixed on the fixing base 2 , with the middle portion facing the opening 21 .

[0045] One end of the bracket 5 is movably arranged in the fixing base 2, and the other end extends out of the fixing base 2. The length of the bracket 5 extending out of the fixing base 2 can be adjusted, wherein the bracket 5 and the sensor 7 are arranged on the same side of the fixing base 2. In other words, the ends of the bracket 5 and the detection member 4 are both arranged on the same side of the fixing base 2 and extend into the interior of the lock at the same time, and play different roles respectively.

[0046] Optionally, an elongated hole 51 is provided at one end of the bracket 5 placed in the fixing seat 2 , and the length direction of the elongated hole 51 is arranged along the length direction of the bracket 5 . A fastener 71 extends into the fixing seat 2 and into the elongated hole 51 .

[0047] In this embodiment, the extended length of the bracket 5 is equal to the distance b between the first end surface 12 and the second end surface 13 .

[0048] The extension length of the bracket 5 can be adjusted in one embodiment by finding an external reference, which can be a common ruler or other structure. The extension length of the bracket 5 is measured and then measured with a ruler. If it meets the standard, the bracket 5 is no longer adjusted. If it is not enough, it can be adjusted according to the situation until it meets the standard.

[0049] Furthermore, in the present embodiment, a regulator 8 is specially provided for adjusting the extension length of the bracket 5. Optionally, in the present embodiment, the height of the bracket 5 on the fixing seat 2 is different from the height of the detection member 4 and will not overlap. The regulator 8 includes a positioning seat 81, and a positioning groove 811 is provided at one end of the positioning seat 81. The shape of the positioning groove 811 is adapted to the shape of the fixing seat 2 and the detection member 4, so that the fixing seat 2, the detection member 4 and the bracket 5 are placed on the positioning seat 81 as a whole. When placed, the fixing seat 2 and the detection member 4 are placed in the positioning groove 811, and positioning can be achieved. Since in the present embodiment, the bracket 5 and the detection member 4 are not at the same height and will not overlap, the positioning groove 811 may not be provided with a structure adapted to the shape of the bracket 5. In the present embodiment, when installed, the bracket 5 is located above the positioning groove 811. The other end of the positioning seat 81 is provided with a slider 82 and an adjusting rod 83. The slider 82 is slidably connected to the positioning seat 81. The slider 82 is close to the end of the positioning slot 811 corresponding to the sensor 7. The adjusting rod 83 is fixedly connected to the slider 82. The sliding direction of the slider 82 is set along the length direction of the bracket 5. The bracket 5 is located above the positioning slot 811 and points to the side of the slider 82 away from the adjusting rod 83. Before adjusting the length of the bracket 5, the slider 82 is first adjusted to the required position by the adjusting rod 83, and then the length of the bracket 5 is adjusted so that the end of the bracket 5 contacts the side of the slider 82, that is, the length of the bracket 5 is adjusted.

[0050] Of course, in some embodiments, the height of the bracket 5 on the fixing seat 2 may be the same as or partially overlap with the height of the detection member 4, and in this case, the positioning groove 811 may be partially designed according to the height of the bracket 5 and the detection member 4. In this case, the positioning groove 811 also needs to be provided with a structure that matches the shape of the bracket 5, and the bracket 5 extends in the positioning groove 811 to contact the slider 82, so the positioning groove 811 needs to be connected with the groove structure of the slider 82 during sliding.

[0051] Furthermore, a ruler is provided on the adjusting rod 83, and the slider 82 can be slid to the target position by the ruler. The target position is determined by converting the length of the bracket 5. At this time, there is no need to use external measuring tools such as rulers, and the operation is convenient and intuitive.

[0052] After the adjustment is completed, the bracket 5 is locked by the fastener 71. The fastener 71 can be a screw. The screw is turned to loosen the bracket 5. At this time, the length of the bracket 5 extending out of the fixing seat 2 can be adjusted. When the bracket 5 is adjusted to the required length, the screw is tightened to fix and lock the bracket 5. Then, the fixing seat 2 is held and the bracket 5 and the detection member 4 are inserted into the lock. During the detection, the bracket 5 is inserted from the first end face 12 of the lock core 1 toward the second end face 13 of the lock core 1 until the end of the bracket 5 contacts the second end face 13 of the lock core 1 and is blocked by the second end face 13. At this time, it means that the bracket 5 and the detection member 4 have been positioned. The detection member 4 is facing a certain blade 11 at this time. The sensor 7 on the detection member 4 can be detected. After the blade 11 is measured, the detection member 4 is slid to produce the next pause feeling, indicating that the detection end of the detection member 4 reaches the next blade 11. The sensor 7 on the detection member 4 detects again. The operation is continued until the last blade 11 is detected.

[0053] Furthermore, a locking member 72 is included, the locking member 72 extends into the fixing seat 2 and abuts against the detection member 4. Optionally, the side wall of the detection member 4 is provided with a locking hole 41, the locking member 72 extends into the locking hole 41 to lock the detection member 4 so that it cannot continue to slide, and the sensor 7 performs detection at this time. Such a setting makes the sensor 7 more stable and reliable during the detection process.

[0054] Furthermore, a scale structure for directly checking the position reached by the elastic component 6 is provided on the side of the dial 3 where the fixed groove 2 is exposed. The scale structure here is only for checking and is not like the scale groove 31 located on the inner side of the dial 3, which requires a groove to cooperate with the elastic component 6. Therefore, the scale structure here can be the scale groove 31 or not.

[0055] For example, in some embodiments, a scale groove 31 is also provided on one side of the scale disk 3 exposed from the fixing seat, and the scale grooves 31 on both sides of the scale disk 3 are collinear.

[0056] Specifically, in order to realize that when the detection member 4 slides from one scale groove 31 to the next scale groove 31, that is, to realize that the sensor 7 at the end of the detection member 4 moves from one blade 11 position to the next blade 11 position, the spacing between two adjacent scale grooves 31 is the same as the spacing between two adjacent blades 11 on the lock core 1. The scale grooves 31 correspond to the serial numbers of each blade 11 on the lock core 1 to be detected, for example, the blades 11 on the lock core 1 are arranged 1, 2, 3..., and accordingly, the scale grooves 31 correspond to the numbers 1, 2, 3..., in other words, the scale grooves 31 are arranged according to the structure of the lock core 1 to form a mapping relationship.

[0057] In other embodiments, a scale line (not shown) is provided on the side of the scale plate 3 exposed from the fixing base 2 , and the scale line is colinear with the scale groove 31 .

[0058] In the above-mentioned embodiment in which the dial plate 3 and the fixing base 2 are detachably connected, it is only necessary to replace the dial plate 3 with different spacings to detect the internal parts of the lock of different models.

[0059] Optionally, the scale plate 3 is arranged on two opposite sides of the fixing base 2 .

[0060] The two ends of the spring along the axis direction point to the scale discs 3 on both sides respectively, and two steel balls 62 are provided, and one steel ball 62 is provided at each end of the spring pointing to the scale disc 3. This arrangement allows the device to be applied to more scenarios.

[0061] In order to slide in one direction and detect all the blades 11, preferably, the elastic component 6 is slid to the scale line or scale groove 31 position of the label 1, and then slides once for each detection to move to the next scale line or scale groove 31. The first blade 11 corresponding to the label 1 is set to be a blade 11 close to the first end surface 12, such as Figure 1 As shown, the length of the detector 4 corresponding to the first blade 11 is the longest. At this time, the distance between the end of the detector 4 and the end of the bracket 5 is Figure 1 c in.

[0062] The device for accurately locating the position of the internal parts of the lock provided by the present invention does not need to disassemble the lock. It only needs to adjust the length of the bracket 5 to the required length, and then extend the bracket 5 and the detection member 4 into the lock until the bracket 5 presses against the target position (the first end face) and cannot move forward. It can be determined that the bracket 5 is in place, and then the detection member 4 can be adjusted to locate each blade 11, and then the sensor 7 on the detection member 4 is used for detection, which can greatly save measurement costs and shorten the measurement cycle.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
