Technical Field
[0001] This utility model relates to the field of card manufacturing technology, specifically to a card size measuring tool. Background Technology
[0002] Card games, also known as playing card games, are a type of tabletop game. Game cards come in various forms, such as playing cards and mahjong tiles, and people use these cards to play games. Game cards need to conform to standard sizes so that players can easily use the card sleeves and avoid problems during shuffling and dealing. Therefore, card manufacturers need to ensure the precise size of each card to prevent deviations during cutting and printing, avoiding material waste or affecting the quality of the finished product. Currently, quality inspectors typically use measuring tapes to measure cards during random checks. However, due to the variability of the cards and variations in human handling techniques, the measured values can easily deviate significantly. Therefore, there is an urgent need to design a specialized measuring tool for measuring the length and width of game cards. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model proposes a card size gauge. The object to be measured is placed in the card slot, with the long side of one side of the object against the wall of the card slot. The dial is then pushed again, causing the protrusion to abut against the other side of the object. The reading on the dial at this time is the length or width value of the object. During measurement, the inspector can press their hand against the card surface to prevent the card from being squeezed and deformed, ensuring the accuracy of the measurement value.
[0004] The technical solution adopted by this utility model is as follows: A card size measuring tool includes a body and a dial indicator. The body is provided with a card slot for placing the object to be measured. The dial indicator includes a support rod, a protrusion, a slide rod and a dial. The support rod is fixedly connected to the side wall of the body. The dial is slidably connected to the support rod. One end of the slide rod is fixedly connected to the dial. The other end of the slide rod passes through the support rod and is connected to the protrusion. The bottom surface of the card slot is provided with a sliding groove. The protrusion slides into the sliding groove, and the top surface of the protrusion protrudes out of the sliding groove.
[0005] Initially, push the dial to make the protrusion slide along the groove until the protrusion touches the wall of the slot. This is considered reaching the reference surface, and the dial returns to zero. This can be repeated three times for calibration. Then, place the object to be measured into the slot, with the long side of one side of the object against the wall of the slot. Push the dial again so that the protrusion touches the other side of the object. The reading on the dial at this time is the length or width value of the object. When the object to be measured is a deformable object such as a card, the inspector can press the surface of the card with their hand during measurement to prevent the card from being squeezed and deformed, thus ensuring the accuracy of the measurement value.
[0006] Optionally, the support rod includes a first support portion and a second support portion integrally formed with the first support portion. The first support portion is fixedly connected to the body, and the dial is slidably sleeved on the outer peripheral wall of the second support portion. The first support portion is provided with a through hole for the slide rod to pass through, and the through hole extends to the second support portion.
[0007] Optionally, the length of the groove is less than or equal to the length of the slide rod. This ensures that the slide rod, carrying the protrusion, can abut against the groove wall.
[0008] Optionally, the body includes a base plate and a measuring plate disposed on the upper surface of the base plate. The measuring plate is provided with the slot. The width of the measuring plate is smaller than the width of the base plate. The first support is installed on the base plate, and the side of the first support away from the second support abuts against the measuring plate.
[0009] Optionally, the slot has a first straight edge and a second straight edge perpendicular to the first straight edge, the first straight edge movably abutting against the protrusion, and the second straight edge being arranged parallel to the slide rod.
[0010] When the object to be measured is a card, the right angle formed by the intersection of two straight edges can be used to locate the card, making the measurement more convenient.
[0011] Optionally, the base plate has multiple legs evenly distributed on the side facing away from the measuring plate.
[0012] Optionally, the dial is a digital display dial, which allows users to read the numbers more intuitively.
[0013] Optionally, the end face of the base plate is provided with a handle for easy carrying by quality inspectors.
[0014] The beneficial effects of this utility model are as follows: Initially, the dial is pushed so that the protrusion slides along the groove until it touches the wall of the slot, which is considered as reaching the reference surface. The dial returns to zero and can be repeated three times for calibration. Then, the object to be measured is placed in the slot, with the long side of one side of the object against the wall of the slot. The dial is pushed again so that the protrusion touches the other side of the object. At this time, the reading on the dial is the length or width value of the object. The operation is convenient. When the object to be measured is a card or other easily deformable object, the inspector can press the card surface with their hand during measurement to prevent the card from being squeezed and deformed, thus ensuring the accuracy of the measurement value.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.
[0019] like Figure 1 and 2 As shown in the figure, this embodiment discloses a card size measuring tool, including a body 1 and a dial indicator. The body 1 is provided with a card slot 121 for placing the object to be measured. The dial indicator includes a support rod 2, a protrusion 3, a slide rod 4 and a dial 5. The support rod 2 is fixedly connected to the side wall of the body 1, and the dial 5 is slidably connected to the support rod 2. One end of the slide rod 4 is fixedly connected to the dial 5, and the other end of the slide rod 4 passes through the support rod 2 and is connected to the protrusion 3. The bottom surface of the card slot 121 is provided with a sliding groove 124, and the protrusion 3 is slidably engaged with the sliding groove 124, with the top surface of the protrusion 3 protruding out of the sliding groove 124. Initially, push dial 5 to make protrusion 3 slide along slide groove 124 until protrusion 3 touches the wall of slot 121, which is considered to have reached the reference surface. Dial 5 returns to zero. This can be repeated three times for calibration. Then, put the object to be measured into slot 121, with the long side of one side of the object against the wall of slot 121. Push dial 5 again to make protrusion 3 against the other side of the object. The reading on dial 5 at this time is the length or width value of the object. When the object to be measured is a card or other easily deformable object, the inspector can press the card surface with their hand during measurement to prevent the card from being squeezed and deformed, thus ensuring the accuracy of the measurement value.
[0020] like Figure 1 As shown, the support rod 2 includes a first support portion 21 and a second support portion 22 integrally formed with the first support portion 21. The first support portion 21 is fixedly connected to the body 1. The dial 5 is slidably sleeved on the outer peripheral wall of the second support portion 22. The first support portion 21 has a through hole for the slide rod 4 to pass through, and the through hole extends to the second support portion 22. The length of the groove 124 is less than or equal to the length of the slide rod 4. This ensures that the slide rod 4 can abut against the wall of the groove 121 with the protrusion 3.
[0021] like Figure 1 As shown, the main body 1 includes a base plate 11 and a measuring plate 12 disposed on the upper surface of the base plate 11. The measuring plate 12 is provided with the slot 121. The width of the measuring plate 12 is smaller than the width of the base plate 11. The first support part 21 is installed on the base plate 11, and the side of the first support part 21 away from the second support part 22 abuts against the measuring plate 12.
[0022] like Figure 1 As shown, the card slot 121 has a first straight side 122 and a second straight side 123 perpendicular to the first straight side 122. The first straight side movably abuts against the protrusion 3, and the second straight side 123 is arranged parallel to the slide rod 4. When the object to be measured is a card, the right angle formed by the intersection of the two straight sides can be used to position the card, making the measurement more convenient.
[0023] like Figure 2 As shown, the base plate 11 has multiple legs 6 evenly distributed on the side facing away from the measuring plate 12. The legs 6 can be made of rubber and serve to absorb shock.
[0024] In this embodiment, the dial 5 is a digital display dial 5, which allows users to read the numbers more intuitively.
[0025] like Figure 1 As shown, the end face of the base plate 11 is provided with a handle 7, which facilitates carrying by quality inspectors.
