Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a splicing rod for a six-way connector. Background Technology

[0002] With the development of the times, modular furniture has gradually become popular. Modular furniture is simple to assemble, easy to standardize production and on-site assembly, and is especially popular among people who like to do DIY. The core of modular furniture design is to divide the furniture into easy-to-assemble unit panels. The panel connectors are mechanisms specifically used to connect and fix adjacent panels. Currently, some commonly used panel connectors have complex structures that require professional tools for connection, which is not conducive to manual DIY operations. Some have poor assembly precision, and the structure is unstable after assembly, and it is easy to fall apart under stress. In order to solve this problem, our company has applied for a furniture panel quick-assembly splicing kit with application number 2023210103259. This kit has good precision and stable structure. However, in actual use, assemblers have reported that when connecting the six-way connector to the splicing rod, because the connection bolt is used in the middle, the six-way connector and the splicing rod need to rotate relative to each other. At the end point of the rotation, the splicing surface of the six-way connector and the end face of the splicing rod often cannot be aligned exactly, requiring manual adjustment. However, after adjustment, there is usually a certain gap in the middle. Utility Model Content

Both the screw drive mechanism and the forward screw are mounted on the mounting plate. When the splicing plug is inserted into the positioning slot, a portion of it abuts against the bottom of the slot. The abutment position is provided with an internal screw locking hole that aligns with the external screw locking hole. The nut screw can be screwed between the external screw locking hole and the internal screw locking hole to lock the splicing plug in place. At this time, the forward screw is located on the central axis of the splicing rod, and its top end is aligned with the threaded connection hole of the six-way connector. The screw drive mechanism can drive the forward screw to rotate forward and enter the threaded connection hole of the six-way connector.

[0005] In a preferred embodiment of this utility model, the screw driving mechanism includes a transmission gear, a starting gear, and a transmission shaft. A threaded guide structure is provided at the front end of the inner side of the insert plate, and a starting gear seat is provided at the rear end. A transmission shaft positioning seat is provided between the starting gear seat and the threaded guide structure.

The center lines of the starting gear mounting hole and the transmission shaft positioning hole are collinear. The transmission gear includes a transmission spiral gear and a transmission shaft. The starting gear includes... The device includes a starting volute and a starting shaft. The starting shaft is rotatably mounted in the mounting hole of the starting gear. The tail end of the starting shaft, passing through the plate, has a transmission groove. The starting shaft of the starting gear is rotatably inserted into the mounting hole of the starting gear. After installation, the starting volute and the transmission volute mesh with each other. A transmission insertion hole is formed in the middle of the starting volute. The tail end of the transmission shaft has a plug that matches the transmission insertion hole. After the plug is inserted into the transmission insertion hole, the shaft body passes through the positioning hole of the transmission shaft, and the other end is linearly slidably connected to the screw of the advancing screw through a pin groove structure. At this time, the external thread of the advancing screw is tightly fitted with the thread guide structure. The top of the transmission gear has a positioning protrusion, and the shaft body has a positioning ring groove that matches the positioning protrusion. When the plug at the tail end of the transmission shaft is inserted into the transmission insertion hole in the middle of the starting gear, the positioning protrusion just abuts against the positioning ring groove. The pin groove structure includes a limiting pin, a sliding sleeve hole at the bottom of the screw that matches the top of the drive shaft, and a pin connection hole at the top of the drive shaft. A straight limiting elongated hole is provided on the side of the sliding sleeve hole. After the top of the drive shaft is inserted into the sliding sleeve hole, the limiting pin passes through the straight limiting elongated hole and then inserts into the pin connection hole. When the splicing plug is inserted, the tops of both the starting gear seat and the drive shaft positioning seat abut against the inner wall of the straight hole. The internal screw locking hole is located on the top of the starting gear seat. At this time, the center lines of the starting gear mounting hole and the drive shaft positioning hole are collinear with the center line of the straight hole.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] Please see Figures 1 to 8 The embodiments of this utility model include:

[0027] A splicing rod 2 for a six-way connector 1, wherein each splicing surface of the six-way connector 1 is square, and each splicing surface has a threaded connection hole in the middle and positioning protrusions at the four corners of each splicing surface. The cross-section of the splicing rod 2 is a square matching the splicing surface, and the four corners of the cross-section have grooves matching the protrusions. The four sides of the splicing rod 2 have long grooves of the same specification, and the opening of the long groove has a pressure lip structure. A through straight hole is provided in the middle of the rod body. The splicing rod includes a rod body, a splicing plug 2, and a grommet screw 4. The two ends of the splicing rod 2 have positioning slots 201 of the same shape. The bottom of the positioning slot 201 is the inner wall of the corresponding straight hole. The opening of the positioning slot 201 is the opening of the end of the long groove. The bottom of the positioning slot 201 has a through external screw locking hole 202. The overall outline of the splicing plug 3 matches the shape of the positioning slot 201. The splicing plug 3 includes a plate seat 30. 1. The advancing screw 302 and the screw driving mechanism are both installed on the insert plate base 301. When the splicing plug 3 is inserted into the positioning slot 201, a part of the area abuts against the bottom of the slot. The abutting position is provided with an inner screw locking hole 3017 that is aligned with the outer screw locking hole 202. The nut screw 4 can be screwed into the space between the outer screw locking hole 202 and the inner screw locking hole 3017 to lock the splicing plug 3. At this time, the advancing screw 302 is located on the central axis of the splicing rod 2, and its top end is aligned with the threaded connection hole of the six-way connector 1. The screw driving mechanism can drive the advancing screw 302 to rotate forward and enter the threaded connection hole of the six-way connector 1.

[0028] The screw drive mechanism includes a transmission gear 305, a starting gear 304, and a transmission shaft 303. A threaded guide structure is provided at the front end of the inner side of the insert plate 301, and a starting gear seat 3014 is provided at the rear end. A transmission shaft positioning seat 3015 is provided between the starting gear seat 3014 and the threaded guide structure. A transmission gear mounting hole 3013 penetrating the plate surface is provided between the transmission shaft positioning seat 3015 and the starting gear seat 3014. The starting gear seat 3014 has a starting gear mounting hole, and the transmission shaft positioning seat 3015 has a transmission shaft positioning hole. The center lines of the starting gear mounting hole and the transmission shaft positioning hole are collinear. The transmission gear 305 includes a transmission volute 3051 and a transmission shaft 3052. The starting gear 304 includes a starting volute 3041 and a starting shaft 3042. The transmission shaft 3052 is rotatably installed in the transmission gear mounting hole 3013. The tail end of the transmission shaft 3052 passing through the plate surface is provided with a transmission groove. The starting shaft 3042 of the starting gear 304 is rotatably installed into the starting gear mounting hole. After installation, the starting volute 3041 and the transmission volute 3051 mesh with each other. The starting volute 3041 has a transmission insertion hole 3043 in the middle. The tail end of the transmission shaft 303 is provided with a plug 3033 that matches the transmission insertion hole 3043. After the plug 3033 is inserted into the transmission insertion hole 3043, the shaft body 3041 passes through the transmission shaft positioning hole, and the other end is linearly slidably connected to the screw 3021 of the advance screw 302 through a pin groove structure. At this time, the external thread 3023 of the advance screw 302 is tightly fitted with the thread guide surface 3016. In this way, during actual splicing, on-site personnel only need to use a wrench 5 that matches the transmission groove to rotate the forward screw 302, horizontally align the end of the splicing rod 2 and the splicing surface of the six-way connector 1, and connect the two together, and the connection is stable and reliable.

[0029] The transmission gear 305 has a positioning protrusion 3053 on its top, and the transmission shaft has a positioning ring groove 3034 that matches the positioning protrusion 3053. When the plug 3033 at the tail end of the transmission shaft 3 is inserted into the transmission insertion hole 3043 in the middle of the starting gear 304, the positioning protrusion 3053 just abuts against the positioning ring groove 3034. This structural design is to prevent the transmission shaft 3 from slipping forward during use after installation, causing local wear between the transmission insertion hole 3043 and the plug 3033, and in severe cases, even detachment, leading to the failure of the entire splicing plug 3.

[0030] The pin groove structure includes a limiting pin 306, a sliding sleeve hole at the bottom of the screw 3021 that matches the top of the drive shaft 303, and a pin connection hole 3032 at the top of the drive shaft 303. A straight limiting elongated hole 3022 is provided on the side of the sliding sleeve hole. After the top of the drive shaft 303 is inserted into the sliding sleeve hole, the limiting pin 306 passes through the straight limiting elongated hole 3022 and is inserted into the pin connection hole 3032. This pin groove structure connects the screw 3021 and the drive shaft 303 together and allows them to slide relative to each other along the straight limiting elongated hole 3022. In actual use, rotation of the drive shaft 303 will drive the screw 3021 to rotate via the limiting pin 306, without hindering the forward screw 302 from moving forward linearly along the threaded guide surface 3016 during this process.

[0031] When the splicing plug 3 is inserted, the tops of both the starting gear seat 3014 and the transmission shaft positioning seat 3015 abut against the inner wall of the straight hole. The inner screw locking hole 3017 is located on the top of the starting gear seat 3014. At this time, the center lines of the starting gear mounting hole and the transmission shaft positioning hole are collinear with the center line of the straight hole. In this way, after the entire splicing plug 3 is inserted, it can obtain stable support from the straight hole portion of the splicing rod 2. Moreover, after the XGIMI screw 4 is installed, it can effectively restrict the horizontal movement of the splicing plug 3. This ensures that the direction of the forward screw 302 can be aligned with the six-way connector 1 after installation.

[0032] The threaded guide structure is a threaded guide surface 3016 that matches the external thread 3023 of the advance screw 302. The threaded guide structure is designed as a threaded guide surface 3016 because the threaded guide surface 3016 has a larger width, which can stably support the advance screw 302 and make the advance screw 302 more directional when in use.

[0033] The transmission groove can be in the shape of a straight line, cross, hexagon, or triangle, and the shape of the tip of the tightening wrench 5 matches the shape of the transmission groove. In actual implementation, a hexagonal shape is generally used, and the wrench 5 is an internal hex wrench.

[0034] The outer side of the insert plate 301 is wider than the width of the slot opening, and the outer side is provided with clearance steps 3012 on both sides that match the pressure eaves structure. In this way, when inserted, the pressure eaves structure can just press down on the clearance steps 3012, so that the entire insert plate 301 will not fall out of the slot.

[0035] The maximum forward extension of the advancing screw 302 is equal to the length of the internal thread portion of the threaded connection hole of the six-way connector 1. The length of the external thread 3023 on the advancing screw 302 is less than the length of the internal thread portion of the threaded connection hole of the six-way connector 1. This ensures that when the advancing screw 302 rotates forward and enters the threaded connection hole of the six-way connector 1, the two parts perfectly match, and the end of the splicing rod 2 can fit tightly against the splicing surface of the six-way connector 1. The purpose of the external thread 3023 on the advancing screw 302 being less than the length of the internal thread portion of the threaded connection hole of the six-way connector 1 is to allow the advancing screw 302 to disengage from the threaded guide surface 3016 when it is fully inserted into the threaded connection hole. This allows the splicing rod 2 to be pulled, keeping its end face close to the splicing surface of the six-way connector 1, ensuring that the protrusions on the splicing surface can be directly inserted into the slot at the end of the splicing rod 2 without misalignment.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
