[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0035] Example 1: Hook-type cargo channel, see Figure 1-8 As shown, it has a cargo channel carrier, which serves as the structural support component of the entire hook-type cargo channel. This carrier can be integrally injection molded using lightweight materials such as plastic, resulting in more economical processing costs and improved quality stability. In this embodiment, the cargo channel carrier is a generally rectangular plastic body 4. To further meet the requirements of lightweight design, the plastic body can be structurally designed with corresponding hollow structures to reduce material usage and achieve weight reduction. A notch 5 is located at the upper part of the delivery end of the plastic body, thus forming a front suspension part 18 at the front end of the cargo channel carrier. The notch allows goods on the hook to fall to the sales area. The outlet of the machine has an arc-shaped portion 5a extending from the surface of the plastic body, an inwardly recessed horizontal portion 5b connected to the arc-shaped portion, and an obliquely raised portion 5c connected to the inwardly recessed horizontal portion. Since the cargo channel carrier shell is composed of two joined halves, the structure of the notch here remains the same in both halves, and the gap between the two halves is for the hooks to pass through. The cargo channel carrier is equipped with a motion mechanism that circulates along the cargo channel carrier. The motion mechanism is, for example, a conveyor belt. The motion mechanism has hooks 6 regularly distributed, which can hook goods. The cargo channel carrier is equipped with a motion mechanism drive device, which is a drive motor. Figure 1 The drive motor has been omitted. Figure 1The opening T near the rear end of the cargo carrier housing shown is the drive motor mounting position. The housing part of the cargo carrier is provided with a motion mechanism channel 7. The motion mechanism channel formed inside the plastic body allows the conveyor belt to circulate here, and the surface of the plastic body is provided with a motion gap 8 for the hooks installed on the conveyor belt to pass through. The motion mechanism channel encloses a hollow cavity 9 located inside the cargo carrier housing part. The cargo carrier has a cargo carrier fixing hole 10 that passes laterally through the hollow cavity. The two ends of the motion mechanism channel are respectively provided with a motion mechanism steering guide assembly chamber 11 and a motion mechanism main guide assembly chamber 12. The motion mechanism steering guide assembly chamber 11 is equipped with a conveyor belt steering wheel, while the motion mechanism main guide assembly chamber 12 is equipped with a conveyor belt main guide wheel connected to the motor. The above structure can refer to the prior art.

[0036] It is worth mentioning that, see Figure 1-2 As shown, the front suspension portion 18 of the cargo channel carrier forms a suspension-type inner cavity 18a. This suspension-type inner cavity is distributed on one half of the cargo channel carrier shell. In this embodiment, the suspension-type inner cavity is distributed in the right half of the cargo channel carrier shell. See [reference needed]. Figure 1-6 As shown, a micro switch 19 that mates with a hook is installed in the suspended inner cavity. The micro switch is connected to a control board. An end cap 20 is detachably provided on the suspended inner cavity. A micro switch external wiring groove 21 is provided on the outer side of the cargo channel carrier housing. The wiring harness is constrained in the groove, which facilitates maintenance and replacement. The micro switch external wiring groove extends to the rear end of the cargo channel carrier housing.

[0037] See Figure 2-6 As shown, the suspended cavity has a cavity bottom plate 18a-1 with a micro switch mounting port. Two micro switch circuit board fixing posts 18a-2 are positioned opposite each other on the cavity bottom plate. The cavity top plate of the suspended cavity has an upper spring clip fixing groove 18a-3, and the cavity bottom plate of the suspended cavity has a lower spring clip fixing groove 18a-4. The end cap has a cover plate portion 20a and a side enclosure portion 20b circumferentially disposed on the cover plate portion and matching the shape of the suspended cavity. The side enclosure portion has a… A wire harness passage 20c is provided for the wire harness to pass through. The top plate and bottom plate of the side enclosure are respectively provided with an upper spring 20b-1 and a lower spring 20b-2. The upper spring is located in the upper spring fixing groove 18a-3 and the lower spring is located in the lower spring fixing groove 18a-4. The micro switch can be quickly disassembled and assembled from the suspended cavity through the spring-type structure. The spring-type structure itself has high stability and can easily complete the disassembly and assembly operations when working in the vending machine.

[0038] Example 2: This example differs from Example 1 in that, in order to maintain the microswitch arm and quickly complete the disassembly and assembly of the cargo channel carrier itself, a quick-disassembly structure is provided on the cargo channel carrier to meet the above requirements. See also Figure 9-13As shown, the hook-type cargo channel has a cargo channel carrier, which serves as the structural support component of the entire hook-type cargo channel. This carrier can be integrally injection molded using lightweight materials such as plastic, resulting in more economical processing costs and improved quality stability. In this embodiment, the cargo channel carrier is a generally rectangular plastic body 4. To further meet the requirements of lightweight design, the plastic body can be structurally designed with corresponding hollow structures to reduce material usage and achieve weight reduction. At the upper part of the outlet end of the plastic body, there is a notch 5. This notch has an arc-shaped portion 5a extending from the surface of the plastic body, an inwardly recessed horizontal portion 5b connected to the arc-shaped portion, and an obliquely raised portion 5c connected to the inwardly recessed horizontal portion. The cargo channel carrier is equipped with a motion mechanism that circulates along the cargo channel carrier. The motion mechanism, for example, is a conveyor belt. The motion mechanism has hooks 6 regularly distributed throughout, which can hook goods. The cargo carrier is equipped with a motion mechanism drive device, which is a drive motor. The housing of the cargo carrier has a motion mechanism channel 7. The motion mechanism channel formed inside the plastic body allows the conveyor belt to circulate within it. The surface of the plastic body has movement gaps 8 for the hooks mounted on the conveyor belt to pass through. The motion mechanism channel encloses a hollow cavity 9 located within the housing of the cargo carrier. The cargo carrier has cargo carrier fixing holes 10 that pass laterally through the hollow cavity. At both ends of the motion mechanism channel are a motion mechanism steering guide assembly chamber 11 and a motion mechanism main guide assembly chamber 12. The motion mechanism steering guide assembly chamber 11 is equipped with a conveyor belt steering wheel 13, while the motion mechanism main guide assembly chamber 12 is equipped with a conveyor belt main guide wheel 14 connected to the motor. The cargo carrier fixing hole is provided with a V-shaped fixing part on the side wall of the hollow cavity. The V-shaped fixing part has a fixing column part 1 forming the top of the V-shaped fixing part, an outer extension part 2 forming an angle α with the fixing column part, and a fixing root part 3 connected to the free end of the outer extension part. The fixing root part is located at the corner position between the inner side wall of the cargo carrier fixing hole and the inner side wall of the motion mechanism channel part. This V-shaped fixing part can not only improve the structural strength of the plastic structural layer in various parts of the plastic body, but also take into account the use of the fixing column part of the V-shaped fixing part as a screw fixing column. It is worth mentioning that the V-shaped fixing part is integrally formed on the cargo carrier. It should be noted that each of the V-shaped fixing parts occupies half of the overall structure in the split structure of the cargo channel carrier. This facilitates the processing and installation of the plastic body and better meets assembly requirements. One V-shaped fixing part of the plastic body has a guide post 15 at its fixing root, and the other corresponding V-shaped fixing part has a docking guide hole 16 at its fixing root. This allows for rapid positioning during the installation of the two halves of the plastic body and improves the structural strength and stability of the two halves after installation. The arrangement of the guide posts and guide holes facilitates the disassembly and assembly of the cargo channel carrier and is crucial for the rapid maintenance of the microswitch's boom.

[0039] In addition, in this embodiment, the micro switch adopts an external wiring layout and is distributed at the front of the hook-type cargo channel, with the same structure as in embodiment 1.

[0040] Example 3: A hook-type cargo channel, which differs from the first embodiment in that the hook-type cargo channel is equipped with a separate blocking device, see [link to example]. Figure 14-15 As shown, the blocking device has a head 17-1 and a body 17-2. The body has a rear body plate 17-2a and two body side plates 17-2b disposed on the rear body plate. The body side plates have V-shaped notches 17-2c. The body side plates are provided with snap-fit ​​spring clip structures 17-2d. The rear body plate is provided with symmetrical trapezoidal shell parts 17-2e near the V-shaped notches. The trapezoidal shell parts are provided with cross-shaped support parts 17-2e1 inside. A hook is formed between the two trapezoidal shell parts through a lower gap 17-2f.

[0041] The head has a rear head plate 17-1a disposed on the upper part of the rear body plate and two head side plates 17-1b disposed on the rear head plate. The head has a head top plate composed of a sloping head top plate 17-1c and a flat plate 17-1d. A hollow shell part 17-1e is disposed between the two head side plates. A hook is formed between the hollow shell parts through an upper gap 17-1f. The spacing of the upper gap is smaller than the spacing of the lower gap.

[0042] The hollow shell section and the trapezoidal shell section are connected to a cavity section 17-3. After the hook carrying the goods arrives at the blocking device, the hook first enters the lower gap and uses the rear plate at the rear of the lower gap to touch the goods, causing the goods to fall off the hook. The hook then enters the container cavity section, then the upper gap, and finally exits from the outlet of the upper gap of the blocking device to continue moving forward, completing the next action of hooking up goods.

[0043] The blocking device in this embodiment is an optional structure, and the description of the prior art is omitted in the entire text.

[0044] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
