Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1-7 The first embodiment of this utility model provides a quick-locking pin device, characterized by comprising a positioning rod 1, a spring 2, a spring tube 3, a pin 4, and a pull cap 5; the spring 2 is installed inside the spring tube 3, the pin 4 is installed on the positioning rod 1, the pull cap 5 is installed at one end of the positioning rod 1, and the spring tube 3 has a groove in which the pin 4 is installed. Specifically, the positioning rod 1 is integrally formed; there are two grooves, namely a first groove 3-1 and a second groove 3-2; the positioning rod 1 has a threaded hole in which the pin 4 is installed; the spring 2 is made of spring steel; the spring tube 3 is internally divided into two cavities; and the positioning rod 1 passes through the spring tube 3.

[0027] Positioning rod 1 is the main supporting structure of the quick-locking device. Spring 2 provides fastening force, and Bourdon tube 3 is used to install the spring and limit its range of motion. Pin 4 is installed on positioning rod 1, and pull cap 5 is installed on the other end of positioning rod 1 for easy pulling. When the device is not locked, pin 4 is located in the first groove 3-1 on Bourdon tube 3. When locking is required, pull cap 5 to pull pin 4 out of the first groove 3-1, then rotate pull cap 5 to align pin 4 with the second groove 3-2 on Bourdon tube 3, and slowly release pull cap 5 to allow pin 4 to fall into groove 3-2, thus completing the locking of the device.

[0028] like Figure 2 As shown, the positioning rod 1 is made of heat-treated steel, which is stronger than ordinary quick-locking devices. One end of the positioning rod 1 is used to insert into the locking hole, and the other end is used to connect with the pull cap 5. At the same time, a threaded hole is drilled in the rod body for installing the pin 4, and a flange is provided on the rod body for cooperating with the spring tube 3 to compress the spring 2.

[0029] like Figure 3 As shown, spring 2 is made of spring steel. After heat treatment and cold drawing hardening, it has high strength, a certain degree of flexibility and plasticity, and the number of coils can be set according to actual needs.

[0030] The structure of Bourdon tube 3 is as follows Figure 4 As shown, the tube is mainly divided into two cavities, with an inner cavity with a through hole in the middle of the cavity to facilitate the positioning rod 1 to pass through the entire spring tube 3. During installation, the flange on the positioning rod 1 presses against one side of the spring 2, and the other side of the spring 2 presses against the inner cavity of the spring tube 3. The outer surface of the spring tube 3 is provided with two grooves, namely the first groove 3-1 and the second groove 3-2. When the pin 4 is in the first groove 3-1, it indicates that the device is in an unlocked state. When the pin 4 is in the second groove 3-2, it indicates that the device is in a locked state.

[0031] like Figure 5 As shown, the pin 4 is made of high-strength steel that has undergone heat treatment and has high strength. When in use, it is installed in the threaded hole on the positioning rod 1.

[0032] like Figure 6 As shown, the pull cap 5 is made of aluminum alloy, which is lightweight and has stable strength. The outer surface of the pull cap has a knurled design. The pull cap 5 is connected to the end of the positioning rod 1 and is designed to be round, which makes it easy for the operator to apply force.

[0033] The above devices are suitable for fastening lighter products. When the product is heavier, the above devices can be stacked for locking. Figure 7 As shown, the two sets of quick-locking devices are placed in opposite directions to fix the product on the fixed base. The product is subjected to a fastening force in the 180° direction, which improves the reliability of the locking device.

[0034] In summary, this utility model does not limit the specific materials of the positioning rod and spring, and can be selected according to the required conditions. For example, if the pin locking device needs to lock larger equipment, ordinary carbon steel or stainless steel can be selected. At the same time, this utility model has the characteristics of high strength while having a fast locking function. Through the combined use of the fast locking device, the device can bear heavy products and has high reliability.
