[0032] In actual use, an existing QR code scanning device for a gate machine needs to make a suitable installation box and a suitable arc baffle according to the size of different QR code scanners in order to fix the QR code scanner. Since each different model of QR code scanner may require a different installation box and arc baffle, inventory management may become complicated, and it is necessary to track and manage different types of adapter devices, which increases inventory costs and management difficulties. Therefore, a clamping device for fixing the QR code scanner on the top of the gate is provided, which can fix different types of QR code scanners.

[0033] Embodiment 1:

[0034] like Figures 1 to 5 The utility model provides a gate machine two-dimensional code device.

[0035] Specifically, by Figure 1-5 A gate machine QR code device is provided, comprising a gate machine 1, a QR code scanner 3 and a snap-on assembly 2, the snap-on assembly 2 being used to connect the QR code scanner 3 to the gate machine 1, the snap-on assembly 2 comprising a fixed plate 201 rotatably connected to the inner wall of the gate machine 1, a rotating rod 202 being fixedly mounted on the outer wall of the fixed plate 201, a rotating disk 203 being rotatably connected to the outer wall of the rotating rod 202, the rotating disk 203 being provided with an arc-shaped groove 204, a clamping block 205 being slidably connected to the inner wall of the gate machine 1, a fixing rod 206 being fixedly mounted on the outer wall of the clamping block 205, the fixing rod 206 being located inside the arc-shaped groove 204 and slidably connected to the arc-shaped groove 204, a first rack 207 being fixedly mounted on the bottom of the QR code scanner 3, a limiting block 208 being fixedly mounted on the outer wall of the first rack 207, and a first gear 209 meshingly connected to the first rack 207 is provided on one side of the rotating disk 203.

[0036] The first rack 207 at the bottom of the two-dimensional code scanner 3 is inserted into the gate machine 1. When the first rack 207 moves downward and hits the first gear 209, the rotating first gear 209 will drive the turntable 203 to rotate. When the turntable 203 rotates, the arc groove 204 will also rotate together. The rotating arc groove 204 will drive the fixing rod 206 to move. The moving fixing rod 206 drives the card block 205 to slide along the inner wall of the fixing plate 201. When the card block 205 slides out of the inside of the fixing plate 201, it is just above the limit block 208. At this time, the first rack 207 cannot be pulled out upward because the limit block 208 will hit the card block 205 when the first rack 207 moves upward. It only needs to install the same type of first rack 207 at the bottom of different types of two-dimensional code scanners 3 to fix the two-dimensional code scanner 3. There is no need to replace related parts according to different types of two-dimensional code scanners 3, which reduces the complexity of model configuration.

[0037] Further:

[0038] like Figure 3-Figure 4 It is shown that two sleeves 8 are fixedly installed on the outer wall of the rotating disk 203, and a sleeve rod 9 is slidably connected to the inner wall of the sleeve 8. The end of the sleeve rod 9 away from the sleeve 8 is connected to the outer wall of the first gear 209, and the rotating rod 202 is located between the two sleeves 8.

[0039] The turntable 203 is connected to the first gear 209 through the sleeve 8 and the sleeve rod 9, so that the first gear 209 can drive the turntable 203 to rotate through the sleeve rod 9 and the sleeve 8 when it rotates. When the electric telescopic rod 4 drives the first gear 209 to move, the sleeve rod 9 can also be retracted into the sleeve 8 to enable the first gear 209 to move.

[0040] Further:

[0041] like Figure 2 It is shown that a second rack 12 is installed at the bottom of the QR code scanner 3, and two mounting rods 17 are fixedly installed on the inner wall of the gate machine 1. The outer wall of the mounting rod 17 is rotatably connected to a second gear 18, one of the second gears 18 is meshed with the first rack 207, and the other second gear 18 is meshed with the second rack 12.

[0042] When the second rack 12 moves downward or upward with the first rack 207, it will move along the second gear 18. The second gear 18 prevents the first rack 207 and the second rack 12 from moving easily when not pulled. At the same time, the second gear 18 makes the first rack 207 and the second rack 12 more stable when moving and plays a supporting role. The mounting rod 17 supports the second gear 18, allowing the second gear 18 to rotate around the outer wall of the mounting rod 17.

[0043] Further:

[0044] like Figure 5 It is shown that the gate machine 1 is provided with a square groove 14, the first rack 207 and the second rack 12 are both located inside the square groove 14, an insertion rod 16 is installed on the inner wall of the square groove 14, the insertion rod 16 is located between the first rack 207 and the second rack 12, a blocking block 13 is fixedly installed between the first rack 207 and the second rack 12, the blocking block 13 is located above the insertion rod 16, and the bottom of the blocking block 13 is against the outer wall of the insertion rod 16.

[0045] The square groove 14 provides space for the first rack 207 and the second rack 12 to slide up and down, and the insertion rod 16 limits the blocking block 13, so that the first rack 207 and the second rack 12 can be fixed in position by the insertion rod 16 when they descend to a certain distance, preventing the first rack 207 and the second rack 12 from continuing to move downward. When the blocking block 13 contacts the insertion rod 16, it means that the block 205 has been moved out and does not need to be moved down any further.

[0046] Further:

[0047] like Figure 2 and Figure 5 It is shown that a slide groove 15 is provided between the first rack 207 and the second rack 12 , the insertion rod 16 is located inside the slide groove 15 and is slidably connected to the slide groove 15 , and the first rack 207 and the second rack 12 are both slidably connected to the square groove 14 .

[0048] The slide groove 15 facilitates the insertion of the first rack 207 and the second rack 12 into both sides of the insertion rod 16, and at the same time enables the insertion rod 16 to enter between the first rack 207 and the second rack 12. The first rack 207 and the second rack 12 are slidably connected to the square groove 14, so that the first rack 207 and the second rack 12 can slide along the square groove 14 when entering the gate 1, thereby facilitating the entry of the first rack 207 and the second rack 12.

[0049] Further:

[0050] like Figure 2 It is shown that two limiting rings 19 are fixedly mounted on the outer wall of the mounting rod 17 , the second gear 18 is located between the two limiting rings 19 , the limiting rings 19 abut against the outer wall of the second gear 18 , and the second gear 18 is located above the first gear 209 .

[0051] To prevent the second gear 18 from falling off the outer wall of the mounting rod 17 when rotating along the outer wall of the mounting rod 17, a limiting ring 19 is used to limit the two sides of the second gear 18, thereby preventing the second gear 18 from falling and also preventing the second gear 18 from deflecting when moving.

[0052] Further:

[0053] like Figure 1-Figure 2 It is shown that a fixing ring 10 is fixedly installed at the bottom of the gate 1, and a suction cup 11 is fixedly connected to the bottom of the fixing ring 10. One end of the suction cup 11 away from the fixing ring 10 is tightly attached to the top of the gate 1, and the square groove 14 is located inside the suction cup 11.

[0054] The fixing ring 10 fixes the suction cup 11 under the two-dimensional code scanner 3, and wraps the square groove 14 through the suction cup 11 to prevent debris from entering the square groove 14 and affecting the transmission engagement between the first rack 207 and the first gear 209. If you want to move the scanning angle of the two-dimensional code scanner 3, you can push the two-dimensional code scanner 3 to move, so that the first rack 207 is slightly tilted, and the first gear 209 and the two second gears 18 support the mounting rod 17 to make the first rack 207 and the second rack 12 more stable. Because the material of the suction cup 11 is relatively soft, even if the two-dimensional code scanner 3 is tilted, the suction cup 11 will still cover the periphery of the square groove 14.

[0055] Embodiment 2:

[0056] Further:

[0057] like Figure 2-Figure 3 It is shown that the outer wall of the first gear 209 is rotatably connected to the support rod 5, the inner wall of the support rod 5 is installed with a connecting rod 6, the end of the connecting rod 6 away from the support rod 5 is fixedly installed with a fixed block 7, the outer wall of the fixed plate 201 is fixedly installed with an electric telescopic rod 4, and the telescopic end of the electric telescopic rod 4 is connected to the outer wall of the fixed block 7.

[0058] When the first rack 207 needs to be taken out, the fixed block 7 is driven by the electric telescopic rod 4 to move toward the fixed plate 201, and the connecting rod 6 is driven to move together through the fixed block 7, thereby driving the support rod 5 and the first gear 209 to move toward the turntable 203. When the first gear 209 and the fixed rod 206 are away from the first rack 207 and the limit block 208, the first rack 207 can be pulled out. Since the support rod 5 and the first gear 209 are rotatably connected, the connecting rod 6 can still remain parallel when the first gear 209 rotates.

[0059] Working principle:

[0060] The first rack 207 at the bottom of the two-dimensional code scanner 3 is inserted into the gate machine 1. When the first rack 207 moves downward and hits the first gear 209, the rotating first gear 209 will drive the turntable 203 to rotate. When the turntable 203 rotates, the arc groove 204 will also rotate together. The rotating arc groove 204 will drive the fixing rod 206 to move. The moving fixing rod 206 drives the card block 205 to slide along the inner wall of the fixing plate 201. When the card block 205 slides out of the inside of the fixing plate 201, it is just above the limit block 208. At this time, the first rack 207 cannot be pulled out upward because the limit block 208 will hit the card block 205 when the first rack 207 moves upward. It only needs to install the same type of first rack 207 at the bottom of different types of two-dimensional code scanners 3 to fix the two-dimensional code scanner 3. There is no need to replace related parts according to different types of two-dimensional code scanners 3, which reduces the complexity of model configuration.

[0061] When the first rack 207 needs to be taken out, the fixed block 7 is driven by the electric telescopic rod 4 to move toward the fixed plate 201, and the connecting rod 6 is driven to move together through the fixed block 7, thereby driving the support rod 5 and the first gear 209 to move toward the turntable 203. When the first gear 209 and the fixed rod 206 are away from the first rack 207 and the limit block 208, the first rack 207 can be pulled out. Since the support rod 5 and the first gear 209 are rotatably connected, the connecting rod 6 can still remain parallel when the first gear 209 rotates.

[0062] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
