Hanging fuel dispenser hand-held terminal mounting device

Abstract

This application discloses a handheld terminal mounting device for suspended fuel dispensers, aiming to solve the technical problems of poor versatility, short service life, and high maintenance costs caused by the special design of existing fuel dispenser hoses for mounting handheld terminals. This application uses ordinary fuel dispenser hoses instead of the custom-made hoses for suspended fuel dispensers, and uses pagoda-shaped spring wires instead of the internal wires in the hoses. This not only reduces the manufacturing and maintenance costs of the hoses for suspended fuel dispensers and improves versatility, but also reduces oil leakage and damage, extending service life. Simultaneously, the use of a detachable hose clamp, handheld terminal mounting plate, and mounting box allows the handheld terminal to rotate axially on the fuel dispenser hose, resulting in a simple structure, easy replacement, and reduced maintenance time.

Description

Technical Field

[0001] This application relates to the field of fuel dispenser equipment technology, specifically to a handheld terminal installation device for a suspended fuel dispenser. Background Technology

[0002] The handheld terminal of the suspended fuel dispenser can control the delivery of fuel. When the suspended fuel dispenser is not in use, the hose can be wound inside the suspended reel via the suspended reel mechanism; when the suspended fuel dispenser is in use, the suspended reel can release the hose to achieve the purpose of refueling.

[0003] In existing technology, the fuel dispenser hose and handheld terminal mounting base are integrated into a single design, meaning they cannot be easily disassembled. The fuel dispenser hose also employs a special design to accommodate the internal wiring. Because the handheld terminal mounting base rotates relative to the hose, both the special hose assembly and the mounting base age faster and have a shorter lifespan. Furthermore, when leaks occur due to the internal wiring of the fuel dispenser hose, it is necessary to replace it with the same type of special hose assembly and a matching handheld terminal mounting base. Commonly used fuel dispenser hoses do not have specialized hose connectors or compatible handheld terminal mounting bases, requiring custom purchases, which increases maintenance costs and reduces versatility.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0022] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all commercially available products.

[0023] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] To address the technical problems of poor versatility, short service life, and high maintenance costs caused by the special design of existing fuel dispenser hoses for mounting handheld terminals, this embodiment discloses a hanging fuel dispenser handheld terminal mounting device, such as... Figure 1 As shown, the system includes a wire fixing plate 1 fixed to the suspended fuel dispenser, a spring wire sleeved on the fuel dispenser hose 2 with one end fixed to the wire fixing plate 1, a hose clamp 3 fixed to the fuel dispenser hose 2, a handheld terminal mounting plate 4 coaxially sliding with the hose clamp 3 for axial rotation around the fuel dispenser hose 2, and a mounting box 5 fixed to the handheld terminal mounting plate 4 for mounting the handheld terminal 20. Preferably, the spring wire is a pagoda-shaped spring wire 6. The hose clamp 3 and the handheld terminal mounting plate 4 are both made of plastic engineering, and the remaining parts are made of sheet metal and steel or use relevant standard parts, resulting in a simple structure and low cost. To prevent the pagoda-shaped spring wire 6 from falling off, it is fixed to the wire fixing plate 1 by wire clips. To enable the handheld terminal 20 to control the suspended fuel dispenser, one end of the pagoda-shaped spring wire 6 is connected to the junction box of the suspended fuel dispenser control system through the wire fixing plate 1, and the other end is connected to the handheld terminal 20 through the mounting box 5. Specifically, the pagoda-shaped spring wire 6 has sufficient length to prevent the wire from breaking when the fuel dispenser hose 2 is stretched by external force. When the fuel dispenser hose 2 is coiled, the end of the pagoda-shaped spring wire 6 connected to the handheld terminal 20 retracts outward along with the other end of the fuel dispenser hose 2 that is fixed to the wire fixing plate 1. When the fuel dispenser hose 2 is released, the end of the pagoda-shaped spring wire 6 connected to the handheld terminal 20 extends outward along with the other end of the fuel dispenser hose 2 that is fixed to the wire fixing plate 1.

[0025] In order to make the handheld terminal 20 rotate relative to the fuel dispenser hose, such as Figure 3 As shown, the hose clamping plate 3 includes two clamping rings 7 that are fixed to the fuel dispenser hose, an annular slide rail 9 located on the outer side of the clamping rings 7, and a limiting slider 10 fixed to the annular slide rail 9; preferably, the limiting slider is a limiting screw. Further, as... Figure 4 As shown, the retaining ring 7 includes a symmetrically fitted left half-ring 71 and a right half-ring 72, connecting holes 73 corresponding to the mating ends of the left and right half-rings, a connecting bolt 74 and a connecting nut 75 adapted to the connecting holes 73. Preferably, the connecting hole 73 is a countersunk hole; the left half-ring 71 and the right half-ring 72 are tightened by the connecting bolt 74 and the connecting nut 75 in the connecting holes to clamp the left and right half-rings onto the fuel dispenser hose 2.

[0026] To enable the handheld terminal mounting plate 4 to rotate axially around the fuel dispenser hose, as follows: Figure 5As shown, the handheld terminal mounting plate 4 includes a mounting ring 8 that slides on the annular slide rail 9 and a rotating limiting groove 11 located at a corresponding position on the mounting ring 8 for limiting engagement with the limiting slider 10. Preferably, the radius of curvature of the rotating limiting groove 11 is less than 360° to prevent excessive twisting of the fuel dispenser hose 2 caused by the rotation of the handheld terminal 20. To ensure that the mounting ring 8 is clamped on the annular slide rail 9 for rotation, as shown... Figure 6 As shown, the mounting ring 8 includes a symmetrically fitted mounting ring one 81 and a mounting ring two 82, mounting holes 83 corresponding to the mating ends of the mounting ring one 81 and mounting ring two 82, mounting bolts 84 and mounting nuts 85 adapted to the mounting holes 83, and mounting platforms 86 corresponding to the outer surfaces of the mounting ring one 81 or mounting ring two 82. Preferably, the mounting holes 83 communicate with the fixing holes provided on the mounting box 5. The mounting ring one 81 and mounting ring two 82 are clamped onto the fuel dispenser hose 2 by the mounting bolts 84 and mounting nuts 85, while the mounting box 5 is also fixed onto the mounting platform 86, which facilitates installation and disassembly and improves stability. Specifically, the limiting slider 10 slides within the rotation limiting groove 11, causing the mounting ring 8 to slide on the retaining ring 7, thereby realizing the axial rotation of the mounting ring 8 on the fuel dispenser hose 2.

[0027] To install the handheld terminal 20, such as Figure 2 As shown, the mounting box 5 includes a mounting base 12 fixed on the mounting platform 86, a mounting cover 13 fitted onto the mounting base 12 and fixedly connected to the handheld terminal 20, and a control component located inside the mounting base 12 for controlling the reel of the fuel dispenser hose. To control the coiling and unwinding of the fuel dispenser hose, the control component includes a pin seat 14 fixed inside the mounting base, a microswitch pin 15 slidingly passing through the pin seat 14 and the mounting base 12, a return spring 16 fitted onto the microswitch pin 15 for resetting the microswitch pin 15, a microswitch 17 fixed inside the mounting base 12 corresponding to the microswitch pin 15, and a microswitch pull cord 18 connected to one end of the microswitch pin 15 extending out of the mounting base 12. Preferably, the micro switch 17 and the pin seat 14 can be bolted together using the fixing holes provided in the mounting base 12. One end of the return spring 16 abuts against the limiting part of the micro switch pin 15, and the other end abuts against the pin seat 14, so that the micro switch pin 15 slides downward on the pin seat 14 via the micro switch pull cord 18 and then automatically slides upward to reset. Pulling the micro switch pull cord 18 can drive the micro switch pin 15 to control the opening and closing of the micro switch 17, thereby controlling the coiling and unwinding of the fuel dispenser hose by the hose reel. In order to connect the end of the pagoda-shaped spring wire 6 to the handheld terminal 20, the handheld terminal 20 can be bolted to the mounting cover, and the connecting end of the pagoda-shaped spring wire 6 can be inserted into the mounting box 5 through the gland 19 to connect to the handheld terminal 20.
