Description

Technical Field

[0001] This utility model relates to the field of measurement structures, and more specifically, to a structure for measuring the length inside a shoe. Background Technology

[0002] Shoes are an indispensable part of people's daily lives, and their size is closely related to consumers. In their daily shoe-buying behavior, consumers often determine their purchase based on the size indicated on the shoe. As a result, they often encounter situations where the size indicated on the shoe is different from the actual size, leading to shoes that do not fit properly and causing a lot of inconvenience to consumers.

[0003] Therefore, the inner diameter of shoes needs to be measured before they leave the factory. Currently, the commonly used measuring tool is a combination of a telescopic rod and a measuring tape. The extension and retraction of the measuring tape are matched with the extension and retraction of the telescopic rod. The telescopic rod is first placed inside the shoe body, and then the scale of the measuring tape is read. However, for ease of grip, the current measuring tool also has a handle perpendicular to the telescopic rod, which occupies the space at the shoe opening. When reading the scale, the shoe tongue needs to be opened to check, which is relatively troublesome and needs to be improved. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 As shown in the figure, a specific embodiment of the present invention discloses a shoe inner length measuring structure, including a handle 100, a measuring tape 200, and a telescopic rod 300; the telescopic rod 300 is installed at the bottom of the handle 100 and extends outward along the direction perpendicular to the side wall of the handle; the spring 210 of the measuring tape 200 is installed inside the handle 100, and the measuring tape 220 passes around the top of the handle 100 and extends out from the bottom of the handle near the telescopic rod, with the end of the measuring tape 220 connected to the end of the telescopic rod 300; the top of the handle 100 is provided with a window 160 for viewing the scale of the internal measuring tape 220.

[0024] The aforementioned shoe inner length measuring structure limits and guides the winding of the measuring tape, allowing the measurement scale to be viewed at the top of the handle. The measurement quantity can be obtained without looking at the shoe tongue or collar, making it convenient to use.

[0025] Furthermore, such as Figure 3 , Figure 4 As shown, the handle 100 includes a support frame 110, which includes a support tube 111 open at both ends. Two opposing support plates 112 are fixedly mounted on the top surface of the support tube 111. A telescopic rod 300 is installed at the support tube 111. Multiple guide wheels 120 are rotatably mounted between the two support plates 112, with at least one guide wheel mounted on the top of the support plate and the other guide wheel mounted on the side of the support plate near the telescopic rod. A spring 210 is installed between the two support plates 112. One end of the measuring tape 220 is fixedly connected to the free end of the spring 210. The measuring tape 220 passes around the multiple guide wheels 120 and is connected to the front end of the telescopic rod 300. The measuring tape located on the outside of the handle extends close to the top surface of the telescopic rod. The overall design of the support frame provides installation space and support for the telescopic rod, guide wheels, and measuring tape. In particular, the design of the guide wheels can provide a limiting and guiding effect on the movement of the measuring tape, allowing it to move to the top position of the handle for easy viewing at this location.

[0026] Furthermore, the handle 100 includes a housing, which comprises a first housing 130 and a second housing 140 disposed opposite to each other. The first housing and the second housing are fixedly connected by screws, and an internal cavity is formed that matches the shape of the two support plates. Insertion posts 150 are fixedly provided on the inner walls of the first housing 130 and the second housing 140, and insertion holes 113 are correspondingly provided on the support plate 112. The insertion posts 150 are inserted into the insertion holes 113 to prevent the housing from detaching from the support plate. The tops of the first housing and the second housing are respectively provided with first notches, and the two opposing first notches form the window. The bottoms of the first housing and the second housing are provided with second notches on the side near the telescopic rod, and the two opposing second notches form the exit for the tape measure. A housing is installed on the outside of the support plate to shield and protect the support plate and the installed guide wheels and tape measure components, facilitating user operation. It allows for both gripping and use while maintaining an overall aesthetic appeal. Furthermore, the outer casing restricts the installation of the internal structure. Specifically, multiple sets of round holes are provided on the two support plates for inserting the rotating shaft, with the guide wheel rotating on the shaft. The support plates have a first prismatic hole corresponding to the core of the spring, and a corresponding second prismatic hole at the center of the core. Frame bars are inserted through the first and second prismatic holes to maintain the core in a fixed position, thus completing the necessary installation of the entire spring. Both ends of the rotating shaft and the frame bars are flush with the outer wall of the support plates. Once the outer casing is in place, it restricts the ends of the rotating shaft and frame bars, preventing them from detaching and maintaining the installation fit. Additionally, the inserts are inserted into the corresponding holes, and the first and second housings are then fixed together with screws, ensuring the entire outer casing is mounted on the support plate and will not detach.

[0027] Furthermore, such as Figure 2 , Figure 3 As shown, the telescopic rod 300 includes a first shaft tube 310 and a second shaft tube 320 nested together; one end of the support tube 111 is provided with a narrowed opening adapted to the second shaft tube 320, and the second shaft tube 320 is installed at the support tube 111; a first plug 400 is installed at the end of the support tube 111 away from the second shaft tube 320; a second plug 330 is installed at the end of the first shaft tube 310 away from the second shaft tube 320; a collar 230 is fixedly connected to the end of the tape 220 away from the spring 210. The clamp is installed between the second plug 330 and the first shaft tube 310; a spring 340 is installed inside the first shaft tube 310, the second shaft tube 320, and the support tube 111 to provide elastic force for the telescopic rod to extend outward; the support tube serves as the mounting part of the telescopic rod, and the narrowing opening of the support tube serves as the locking point for the second shaft tube, so that the second shaft tube can be compressed inward but will not detach from that end, forming a multi-stage compression fit, and also providing the necessary space for the insertion and installation of the spring, so as to achieve the overall fit.

[0028] Furthermore, the end of the first shaft tube 310 away from the second shaft tube 320 is sealed, and the end face of the sealed end is provided with a groove 311; a locking block 331 is fixedly provided on the end face of the second plug 330; the shape of the locking block 331 is adapted to the shape of the groove 311 and the inner wall shape of the collar 230; the collar 230 is sleeved on the locking block 331, the locking block 331 is locked in the groove 311 and fixed by bolts, so that the collar is clamped and installed between the end of the second plug and the end of the first shaft tube; a collar is fixedly provided at the end of the tape, which can serve as the installation and mating part with the second plug and the first shaft tube, which can facilitate assembly and use, and can also better standardize the design and scale measurement, and provide accurate calculation.

[0029] Furthermore, such as Figure 2 As shown, a first guide rod 410 is fixedly provided on the end face of the first plug 400 near the telescopic rod 300; a second guide rod 312 is fixedly provided on the inner wall of the sealing end of the first shaft tube 310; the diameters of the second guide rod and the first guide rod are adapted to the inner diameter of the spring, and the two ends of the spring 340 are respectively sleeved on the first guide rod 410 and the second guide rod 312; this can further limit the movement of the end of the spring, prevent the end of the spring from deviating and affecting the overall elastic deformation, avoid damage to the spring, and maintain an effective telescopic movement effect.
