Description

Technical Field

[0001] The utility model relates to a panel connector, in particular to a large-size panel quick-release connection device. Background Art

[0002] In order to facilitate the quick disassembly and assembly of some panels in furniture, someone has disclosed a patent entitled "An adjustable connector for furniture" (Announcement No.: CN205371204U), which includes an adjuster body and a front connector. The adjuster body includes a face cover, a telescopic member, an adjustment plate, and a fixed plate; the front connector has a first connector and a second connector; the telescopic member includes a first telescopic member and a second telescopic member; the adjustment plate is provided with a first channel and a second channel, and the first telescopic member is transmission-connected with a disassembly screw, and the disassembly screw is provided with a trigger. When the front connector is inserted, the first connector and the second connector of the front connector can be automatically stuck by the first telescopic member and the second telescopic member, respectively, to achieve automatic connection; when the front connector is pulled out, the disassembly screw, the first telescopic member, the rotating rod, and the second telescopic member can be driven to automatically return to the starting position. Simply put, the regulator body of this patent is generally fixed on the furniture cabinet, and the front connector is generally fixed on the panel. When the regulator body and the front connector need to be fixed, the two front connectors are directly inserted into the first channel and the second channel. After the telescopic part contacts the front connector, the inclined surface on the telescopic part is squeezed to generate a component force that drives it to retract, thereby achieving the retraction of the telescopic part and the front connector can be fully inserted. However, in actual use, since the telescopic part will generate friction after contacting the front connector, this friction will hinder the retraction of the telescopic part, resulting in the need to apply a lot of pressure to fully push the front connector in, resulting in a poor user experience. Moreover, since the first telescopic part and the second telescopic part are linkage structures, it is difficult to ensure the synchronous insertion of the two front connectors during the manual insertion process, and it is easy for one end to be inserted first, making the insertion of the other end more difficult. Therefore, the furniture hardware industry still needs to solve the problem of the regulator body and the front connector not being smoothly connected and easy to get stuck. Summary of the invention

[0003] The utility model provides a large-size panel quick-release connection device, which solves the problem in the prior art that an adjuster body and a front connector in a panel connector cannot be connected smoothly and are easily stuck.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a large-size panel quick-release connection device, including a plug-in fixture and a front connection code, the plug-in fixture is fixed on the cabinet, the front connection code is fixed on the panel, the front connection code includes a fixing seat, a first plug-in body and a second plug-in body, and the ends of the two plug-in bodies are provided with locking pins, characterized in that: the plug-in fixture is composed of a fixing plate, a telescopic member sliding up and down relative to the fixing plate, a first plug-in cavity formed on the fixing plate, a second plug-in cavity formed on the fixing plate, and a fixing member fixed relative to the plug-in cavity and An adjusting bolt that rotates together, an elastic reset part that drives the telescopic part to slide downward, and a connecting rod part that rotates together relative to the fixed plate; a first clamping part is provided at the lower end of the telescopic part, a second clamping part and an open groove for the locking pin to enter are provided at the upper end of the telescopic part, and a slide groove is also provided on the telescopic part; a swing arm body extending outward is fixed on the adjusting bolt, and a columnar part that slides together with the slide groove is provided on the swing arm body; the connecting rod part is divided into an outer push rod extending to the first plug-in cavity and an inner push rod extending to one side of the swing arm body, with its rotation axis as the boundary.

[0005] The utility model is divided into two states, locked and unlocked. The locking operation method is: first determine whether the first clamping part and the second clamping part will block the locking pin. If they block the locking pin, it is necessary to use a tool to rotate the adjusting bolt to make the swing arm body flip upward, and the columnar part moves along the slide groove and drives the telescopic part to move upward, so that the first clamping part and the second clamping part move upward at the same time, and push the connecting rod to flip until the columnar part rotates to the dead point. At this time, the telescopic part is in a high position. At this time, the two clamping parts are both unlocked and will not have a locking effect on the locking pin. The dead point in the ideal state is the point where the columnar part is farthest from the plug-in cavity. At this time, the axial connection line between the adjusting bolt and the columnar part and the slide groove exert force on the columnar part. The reaction force direction of the parts coincides with that of the parts, so the reaction force cannot generate a component force for the swing arm body to flip, and the columnar part will remain fixed in this position. At this time, the two plug-in bodies on the front connecting code can be aligned with the two plug-in cavities and inserted. Since the two clamping parts at this time will not come into contact with the plug-in bodies, the insertion process of the plug-in bodies is relatively smooth. As the first plug-in body continues to be inserted, the locking pin on the second plug-in body gradually enters the open groove, and the first plug-in body will abut against the outer push rod and drive the outer push rod to flip, so that the inner push rod synchronously pushes the swing arm body to make the columnar part leave the dead point, and the elastic reset part pushes the telescopic part to move downward, driving the first clamping part and the second clamping part to move downward at the same time, until the two clamping parts and the two locking pins on the two plug-in bodies are respectively clamped and fixed;

[0006] The unlocking operation method is: use a tool to rotate the adjusting bolt, so that the swing arm body flips upward, the columnar part moves along the slide slot and drives the telescopic part to move upward, so that the first clamping part and the second clamping part move upward at the same time, and push the connecting rod to flip, until the columnar part rotates to the dead point, in this process, the outer push rod will also push the first plug-in body outward, and then pull the front connector as a whole out of the two plug-in cavities to complete the unlocking. In summary, the utility model is relatively smooth in both unlocking and locking, and has a good user experience.

[0007] Furthermore, the plug-in fixture also includes a sliding seat that slides up and down relative to the fixed plate, a cover plate is fixed on the sliding seat, and the telescopic member slides up and down in the cover plate, a first plug-in frame is integrally fixed to the lower end of the sliding seat, and a second plug-in frame is integrally fixed to the upper end of the sliding seat, two plug-in cavities are formed between the two plug-in frames and the fixed plate, the clamping portion and the outer push rod can both pass through the first plug-in frame, the adjusting bolt and the connecting rod are rotatably fitted on the cover plate, the elastic reset member acts between the sliding seat and the telescopic member, the fixed plate is also rotatably connected with an upper and lower adjusting screw, and the sliding seat is provided with an upper and lower adjusting hole to accommodate the upper and lower adjusting screws, and the sliding seat as a whole can be driven to be fine-tuned up and down by rotating the upper and lower adjusting screws.

[0008] Furthermore, left and right adjustment screws are screwed onto the first plug-in body, and an adjustment hole is opened on the first plug-in frame. When the first plug-in body is plugged and fixed in the first plug-in frame, the left and right adjustment screws are located in the adjustment holes, and the left and right position of the first plug-in body can be fine-tuned by rotating the left and right adjustment screws.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. When the present invention is locked, the plug-in body is only subjected to the reaction force from the outer push rod during the insertion process, and will not come into contact with the clamping part, so the insertion process of the plug-in body is relatively smooth; 2. When the present invention is unlocked, the adjusting bolt is rotated by using a tool to make the swing arm body flip to the side opposite to the plug-in cavity, so that the clamping part is separated from the locking pin until the columnar part rotates to the dead point. During this process, the outer push rod will also push the plug-in body outward, so that the front connector can be easily removed from the plug-in cavity; 3. The locking position of the front connector can be fine-tuned up, down, left and right by rotating the upper and lower adjusting screws and the left and right adjusting screws.

[0019] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4A large-size panel quick-release connection device includes a plug-in fixture 100 and a front connector 200. The plug-in fixture is fixed on a cabinet, and the front connector is fixed on a panel. The front connector includes a fixing seat 210, a first plug-in body 2201, and a second plug-in body 2202. The ends of the two plug-in bodies are provided with locking pins 230. The plug-in fixture is composed of a fixing plate 110, a telescopic member 120 that slides up and down relative to the fixing plate, a first plug-in cavity 1301 formed on the fixing plate, a second plug-in cavity 1302 formed on the fixing plate, and an adjusting bolt 140 that is fixed and rotatably matched with the plug-in cavity. 0. An elastic reset member 150 that drives the telescopic member to slide downward and a connecting rod member 160 that rotates relative to the fixed plate; a first clamping portion 121 is provided at the end of the telescopic member close to the plug-in cavity, a second clamping portion 123 and an opening groove 124 for the locking pin to enter are provided at the upper end of the telescopic member, and a sliding groove 122 is also provided on the telescopic member; a swing arm body 141 extending outward is fixed to the adjusting bolt, and a columnar portion 142 that slides with the sliding groove is provided on the swing arm body; the connecting rod member is divided into an outer push rod 161 extending to the first plug-in cavity and an inner push rod 162 extending to one side of the swing arm body, with its rotation axis as the boundary.

[0020] See Figure 1 and Figure 4 The plug-in fixture also includes a sliding seat 170. The fixing plate is formed with a plurality of inverted "L"-shaped buckles 111 by stamping. These buckles constrain the sliding seat to fit with the fixing plate and allow the sliding seat to slide up and down. A cover plate 190 is fixed on the sliding seat. The telescopic member slides up and down in the cover plate. The elastic reset member is specifically a spring. The cross section of the telescopic member is a "door"-shaped structure. Therefore, a space for accommodating the spring is formed between the telescopic member and the sliding seat. The elastic force of the spring acts between the sliding seat and the telescopic member.

[0021] See Figure 1 and Figure 5 A first plug-in frame 171 is fixed to the lower end of the sliding seat, and a second plug-in frame 175 is fixed to the upper end of the sliding seat. Two plug-in cavities are formed between the two plug-in frames and the fixed plate. Both the clamping portion and the outer push rod can pass through the first plug-in frame. The adjusting bolt and the connecting rod are rotatably matched on the cover plate. The fixed plate is also rotatably connected with an up and down adjusting screw 180. The sliding seat is provided with an up and down adjusting hole 172 for accommodating the up and down adjusting screws. By rotating the up and down adjusting screws, the sliding seat as a whole can be fine-tuned up and down.

[0022] See Figure 1 and Figure 5 The first plug-in body is screwed with left and right adjustment screws 240, and the first plug-in frame is provided with an adjustment hole 173. When the first plug-in body is plugged and fixed in the first plug-in frame, the left and right adjustment screws are located in the adjustment holes, and the left and right positions of the first plug-in body can be fine-tuned by rotating the left and right adjustment screws.

[0023] When the columnar portion rotates to the dead point, the columnar portion abuts against one end of the slide, and the angle between the axis connecting the adjusting bolt and the columnar portion and the moving axis of the telescopic member is between 5° and 10°. Although ideally, there is only one dead point, in reality, due to the existence of static friction, the swing arm body can only be freed from the dead point when the component force generated by the reaction force applied by the slide to the columnar portion for the swing arm body to flip is greater than the static friction between the columnar portion and the slide at this time. The closer the area is to the ideal dead point, the smaller the component force for the swing arm body to flip, and the static friction will become greater and greater. Therefore, the actual dead point is a range, which is determined by the friction coefficient of the material, and the range of the dead point is positively correlated with the value of the friction coefficient. The telescopic member and the columnar portion are conventional metal sheet metal parts, and the corresponding dead range is generally between 0° and ±15°. Furthermore, because the column part needs to be disengaged from the dead point, the connecting rod part needs to flip and push the swing arm body to rotate, and the connecting rod part is pushed and flipped by the plug-in body, and the insertion distance of the plug-in body in the plug-in cavity is fixed, resulting in a small flipping angle of the connecting rod part. Therefore, the actual dead point of the column part needs to be set in an area close to the edge of the dead range, so as to ensure that the connecting rod part can easily push the column part out of the dead point.

[0024] See Figure 4 The rear end of the first plug-in frame is provided with a limit piece 174 for limiting the turning angle of the outer push rod; the end of the outer push rod is provided with an abutment piece 163 for increasing the contact area with the plug-in body.

[0025] See Figure 6 and Figure 7The present embodiment is divided into two states, locked and unlocked. The locking operation method is: first determine whether the first clamping part and the second clamping part will block the locking pin. If the locking pin is blocked, it is necessary to use a tool to rotate the adjusting bolt to make the swing arm body flip upward, and the columnar part moves along the slide groove and drives the telescopic part to move upward, so that the first clamping part and the second clamping part move upward at the same time, and push the connecting rod to flip until the columnar part rotates to the dead point. At this time, the telescopic part is in a high position. At this time, both clamping parts are in an unlocked state and will not have a locking effect on the locking pin. The dead point in the ideal state is the point where the columnar part is farthest from the plug-in cavity. At this time, the axial connection line between the adjusting bolt and the columnar part and the slide groove exert force on the columnar part. The reaction force direction of the parts coincides with that of the parts, so the reaction force cannot generate a component force for the swing arm body to flip, and the columnar part will remain fixed in this position. At this time, the two plug-in bodies on the front connecting code can be aligned with the two plug-in cavities and inserted. Since the two clamping parts at this time will not come into contact with the plug-in bodies, the insertion process of the plug-in bodies is relatively smooth. As the first plug-in body continues to be inserted, the locking pin on the second plug-in body gradually enters the open groove, and the first plug-in body will abut against the outer push rod and drive the outer push rod to flip, so that the inner push rod synchronously pushes the swing arm body to make the columnar part leave the dead point, and the elastic reset part pushes the telescopic part to move downward, driving the first clamping part and the second clamping part to move downward at the same time, until the two clamping parts and the two locking pins on the two plug-in bodies are respectively clamped and fixed;

[0026] The unlocking operation method is: use a tool to rotate the adjusting bolt, so that the swing arm body flips upward, the columnar part moves along the slide slot and drives the telescopic part to move upward, so that the first clamping part and the second clamping part move upward at the same time, and push the connecting rod to flip, until the columnar part rotates to the dead point, in this process, the outer push rod will also push the first plug-in body outward, and then pull the front connector as a whole out of the two plug-in cavities to complete the unlocking. In summary, the utility model is relatively smooth in both unlocking and locking, and has a good user experience.

[0027] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
