Description

Technical Field

[0001] This utility model relates to the technical field of garment hanging and conveying devices, and in particular to a flexible chain fence with a novel connection method. Background Technology

[0002] In automated garment manufacturing lines, lifting the conveyor chain carrying hanging hangers from a low point to a high point is a crucial process. Currently, the two main lifting methods are aluminum arm belt lifting mechanisms and flexible chain lifting mechanisms. Among them, flexible chain lifting mechanisms have significant advantages in flexibility and adaptability because they can flexibly increase or decrease the number of chain links to adapt to different lifting height requirements.

[0003] However, flexible chain lifting mechanisms have an inherent technical flaw: as the lifting height increases, the chain length and its own weight also increase. When the chain length exceeds a certain limit, it will generate severe vibrations during operation, which will not only produce noise but also accelerate the wear between the chain and the drive mechanism. In severe cases, there is even a risk of chain breakage due to excessive load, leading to damage to the mechanism, production line shutdown, and potentially causing personnel safety accidents.

[0004] To address the issues of vibration and stability in long chains, the industry has proposed several solutions involving the addition of guide rails. For example, existing patent CN214988051U discloses a concept of constraining and guiding chain movement by adding guide rails. These solutions have improved chain performance to some extent. However, these guide rail structures themselves or their connection methods may suffer from insufficient rigidity, inconvenient installation, or inadequate chain containment and support, and their stability and convenience still have room for improvement.

[0005] Furthermore, regarding the guiding technology of conveyor chains, existing patent CN208453762U discloses a conveyor chain protection device. This device uses a guide rail with a "C" or "L" shaped cross-section. By setting a guide strip at the top of the guide rail to insert into the inner ring groove of the chain and setting a boss at the bottom to support the chain, it achieves semi-enclosed protection of the chain, effectively preventing chain deformation and hanger detachment. However, the connection of the bend in this patent relies on the cooperation of dovetail groove and dovetail locking block. This connection method can only achieve splicing and positioning in the plane and lacks an effective vertical locking mechanism. When the spliced ​​track is subjected to external force in the vertical direction, there is a risk of loosening and separation. Therefore, a matching hanging system frame needs to be set at the bend for fixation, which is not convenient for flexibly and quickly adjusting the arc radius of the bend according to the production site conditions. Utility Model Content

[0006] The purpose of this invention is to provide a flexible chain fence with a novel connection method to solve the problems mentioned in the background art and improve the stability and convenience of the fence.

[0007] The above-mentioned objective of this utility model is achieved through the following technical solution: a flexible chain fence with a novel connection method, comprising a straight rail and a curved rail, wherein the curved rail is formed by splicing multiple fence splicing blocks with a certain angle end to end, and each splicing end face of the fence splicing block is provided with at least one dovetail boss and a dovetail groove. It also includes an elastic locking block and a fastening groove that cooperates with the elastic locking block, wherein the elastic locking block and the fastening groove are respectively disposed on the two splicing end faces of the fence splicing block; When two adjacent fence panels are joined together, the dovetail protrusion of one fence panel is inserted into the dovetail groove of the other fence panel to achieve interlocking positioning, and at the same time, the elastic locking block of one fence panel is engaged in the locking groove of the other fence panel to achieve locking in the insertion direction.

[0008] Preferably, the splicing end face of the fence splicing block is provided with an installation groove, and the elastic locking block is located in the installation groove and partially protrudes from the splicing end face.

[0009] Preferably, the top of the elastic locking block is flat and protrudes outward from the splicing end face. When two adjacent fence splicing blocks are spliced, the top of the elastic locking block abuts against the top surface of the locking groove.

[0010] Preferably, the side end face of the elastic locking block is an outwardly inclined surface from the bottom to the top.

[0011] Preferably, the elastic locking block is integrally injection molded from an elastic plastic material and the fence splicing block.

[0012] Preferably, the dovetail boss and dovetail groove are distributed on the upper and lower sides of the splicing end face, and the elastic locking block and buckle groove are distributed on the upper side of the splicing end face.

[0013] Preferably, the fence splicing block is provided with through bolt mounting holes, and the fence splicing block near the end of the straight rail is fixed to the straight rail by bolts.

[0014] Preferably, the top of the straight rail is provided with a dovetail buckle.

[0015] The beneficial effects of this utility model are: This utility model achieves interlocking positioning through dovetail protrusions and dovetail grooves, and locks in place through elastic locking blocks and buckle grooves. The combination of the two forms a quick-installation structure that is "securely secured with a single insertion", which completely solves the problem of fence splicing blocks potentially detaching from each other, and greatly enhances the vibration resistance and separation resistance. The individual fence panels of the curved track can be fixed to each other without relying on the hanging system frame. Different angle fence panels can be selected for splicing according to actual needs, and the arc radius and shape of the curved track can be adjusted flexibly and quickly.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0019] Example: like Figure 1-3 As shown, a flexible chain fence with a novel connection method includes a straight rail 1 and a curved rail 2. The curved rail 2 is formed by splicing multiple fence splicing blocks 201 with a certain angle end to end, that is, the two splicing end faces of the fence splicing blocks 201 form an included angle with an angle of 1-10°.

[0020] Each splicing end face of the fence splicing block 201 is provided with at least one dovetail boss 202 and dovetail groove 203, which are distributed on the upper and lower sides of the splicing end face. In this embodiment, as shown... Figure 2As shown, three dovetail protrusions 202 are provided on the upper side of one splicing end face of the fence splicing block 201, and one dovetail groove 203 is provided on the lower side; on the other splicing end face, as shown... Figure 3 As shown, three dovetail grooves 203 are provided on the upper side of the splicing end face, and a dovetail boss 202 is provided on the lower side.

[0021] The fence splicing block 201 is also provided with an elastic locking block 205 and a fastening groove 206 that cooperates with the elastic locking block 205. The elastic locking block 205 and the fastening groove 206 are respectively located on the two splicing end faces of the fence splicing block 201, and the two are distributed on the upper side of the splicing end faces.

[0022] When two adjacent fence splicing blocks 201 are spliced ​​together, the dovetail protrusion 202 of one fence splicing block 201 is inserted from top to bottom into the dovetail groove 203 of the other fence splicing block 201 to achieve interlocking positioning. At the same time, the elastic locking block 205 of one fence splicing block 201 is engaged into the locking groove 206 of the other fence splicing block 201 to achieve locking of the insertion direction.

[0023] like Figure 4 As shown, an installation groove 207 is provided on the splicing end face of the fence splicing block 201, and the elastic locking block 205 is located in the installation groove 207 and partially protrudes from the splicing end face.

[0024] The top of the elastic locking block 205 is a flat surface, namely the end face of the top of the locking block 205a, which protrudes outward from the splicing end face.

[0025] like Figure 5 As shown, when two adjacent fence splicing blocks 201 are spliced ​​together, the top of the elastic locking block 205 abuts against the top surface of the buckle groove 206. At this time, the two fence splicing blocks 201 cannot move in the reverse insertion direction, thus fixing the two together.

[0026] The side end face of the elastic locking block 205, namely the locking block side end face 205b, is an outwardly inclined surface from bottom to top. During the splicing process, one fence splicing block 201 moves downward relative to the other fence splicing block 201, so that the dovetail boss 202 is inserted into the dovetail groove 203. The locking block side end face 205b of the elastic locking block 205 on the downward moving fence splicing block 201 is pressed into the mounting groove 207 by the splicing end face of the other fence splicing block 201. When it reaches the position of the buckle groove 206, the elastic locking block 205 rebounds and a part of it enters the buckle groove 206. At this time, the top end 205a of the elastic locking block 205 will abut against the top surface of the buckle groove 206 to prevent the downward moving fence splicing block 201 from moving upward and causing the two fence splicing blocks 201 to separate.

[0027] Among them, the elastic locking block 205 is integrally injection molded from elastic plastic material and fence splicing block 201.

[0028] The fence splicing block 201 is provided with through bolt mounting holes 204, such as... Figure 5 As shown, the fence splicing block 201 near the end of the straight rail 1 is fixed to the straight rail 1 by bolts 4. A dovetail buckle 101 is provided at the top of the straight rail 1, and the straight rail 1 is fixed to the hanging system frame by the dovetail buckle 101.
