Description

Technical Field

[0001] The present application relates to the technical field of furniture installation, and in particular to a drawer front panel fixing mechanism and a drawer installation device. Background Art

[0002] An assembled drawer is usually a single-sided open six-sided structure consisting of a front panel, a back panel, a bottom panel and two side panels. The front panel of a traditional assembled drawer is provided with a buckle, and the two side panels are respectively provided with a panel connection assembly. By inserting the buckle into the panel connection assembly in an unlockable manner, the front panel and the two side panels are detachably connected to complete the installation. Chinese patent CN113040545A improves the traditional panel connection assembly, so that the user does not need to maintain the position of the movable buckle plate to keep the panel connection assembly in a state where the socket can be removed.

[0003] However, this panel connection assembly requires the forces in multiple directions provided by the special-shaped groove and the movable groove to maintain the static state of the movable buckle plate. When the user pulls the screwdriver out of the cross slot, it is difficult to ensure that the screwdriver is completely perpendicular to the cross slot without touching it. If the screwdriver comes into contact with the screw, it is easy to break the balance of forces in multiple directions, making it impossible for the movable buckle plate to maintain a static state. Moreover, after long-term use of the drawer, the spring is prone to aging or rusting over time, causing its elastic coefficient to change. The elastic force it provides cannot match the multiple forces provided by the special-shaped groove and the movable groove, and the movable buckle plate is also difficult to remain static, affecting the user experience of the panel connection assembly.

[0041] See also Figures 1 to 4 , a drawer front panel fixing mechanism 100 provided in one embodiment of the present application is used to insert a plug 200 and detachably fix the plug 200. Among them, the drawer front panel fixing mechanism 100 is used to be installed on the body of the drawer, such as a side panel or a bottom panel. Preferably, it includes two, and is respectively installed in the mounting grooves of the two side panels of the drawer, and the opening of the mounting groove faces the drawer front panel. The plug 200 is used to be fixedly connected to the drawer front panel, so that the drawer front panel is installed on the drawer body through the detachable fixation between the plug 200 and the drawer front panel fixing mechanism 100. And the installation height and left-right spacing of the drawer front panel can be adjusted by adjusting the positional relationship between the plug 200 and the drawer front panel fixing mechanism 100.

[0042] The drawer front panel fixing mechanism 100 described in the embodiment of the present application includes a fixed plate assembly 110, a movable plate 120, a locking member 130, a pressing member 140 and a reset member 150. The movable plate 120 is movably connected to the fixed plate assembly 110, and the movable plate 120 has an initial position and an unlocking position relative to the fixed plate assembly 110. When the movable plate 120 is in the initial position, the plug 200 is locked by the movable plate 120, and when the movable plate 120 is in the unlocking position, the plug 200 can be removed; the locking member 130 is rotatably connected to the fixed plate assembly 110, and the locking member 130 is provided with a push-locking portion 131, and the push-locking portion 131 is used to rotate to contact the movable plate 120 and drive the movable plate 120 to move from the initial position to the unlocking position; the pressing member 140 is connected to one of the movable plate 120 and the fixed plate assembly 110, and the pressing member 140 is used to push the movable plate 120 to the unlocking position. When 120 is in the unlocked position, it is pressed and contacted with the other one to limit the movable plate 120 in the unlocked position; the movable plate 120 is provided with a first contact portion 122, and the first contact portion 122 contacts with the lock element 130 when the movable plate 120 is in the unlocked position to maintain the position of the lock element 130; the movable plate 120 is also used to be driven by the plug 200 to disengage from the unlocked position and return to the initial position when the plug 200 is inserted into the drawer front panel fixing mechanism 100; the reset member 150 is connected to the lock element 130 and the fixed plate assembly 110, and the reset member 150 is used to drive the lock element 130 to rotate to restore the relative position of the lock element 130 and the fixed plate assembly 110.

[0043] The drawer front panel fixing mechanism 100 involved in the present application, by providing a pressing member 140 and providing a first contact portion 122 on the movable plate 120, enables the movable plate 120 to be fixed in the unlocked position, and also fixes the rotation position of the lock member 130, so that the lock member 130 does not affect the holding of the movable plate 120 in the unlocked position due to the rotation, ensuring that the plug 200 can be smoothly pulled out. The drawer front panel fixing mechanism 100 provided in the present application has a simple structure, is easy to use, and has high reliability.

[0044] Specifically, refer to Figures 1 to 4 as well as Fig.11 The movable plate 120 has a concave position at one side edge, the concave position includes a guide position 120a and a lock position 120b which are connected to each other, and the movable plate 120 has a guide bevel 120c at a position corresponding to the guide position 120a. The plug 200 includes two oppositely disposed plug shells 210, and the plug shell 210 has two oppositely disposed sheet shells, which are connected by a stop column 220. Figure 1 Taking the drawer front panel fixing mechanism 100 in the embodiment as an example, when the reset member 150 is in an unstretched state, that is, the movable plate 120 is located at the lowermost position (the upper and lower positions here refer to the attached figure of the present application). Figure 1 When the moving plate 120 is at the initial position; Figure 2Taking the drawer front panel fixing mechanism 100 in the example, when the movable plate 120 is located at the uppermost position, the movable plate 120 is in an unlocked state. At this time, the plug 200 is inserted into the guide position 120a from left to right, and the push column 220 abuts against the guide bevel 120c. As the plug 200 continues to be inserted, the push column 200 drives the movable plate 120 to move from top to bottom until it moves to the initial position, so that the push column 220 is located in the lock position 120b and is limited, so that the plug 200 cannot be moved out from right to left and is locked.

[0045] In some embodiments, the fixed plate assembly 110 includes a first fixed plate 111 and a second fixed plate 112, the first fixed plate 111 and the second fixed plate 112 are arranged opposite to each other and spaced apart, and the movable plate 120 is arranged between the first fixed plate 111 and the second fixed plate 112; the pressing member 140 is connected to one side of the movable plate 120, and the pressing member 140 protrudes from the surface of the movable plate 120. The first fixed plate 111 or the second fixed plate 112 is provided with an avoidance position, so that in the initial position, the pressing member 140 does not contact the first fixed plate 111 or the second fixed plate 112. When the movable plate 120 moves from the initial position to the unlocking position, the end of the pressing member 140 away from the movable plate 120 moves upward from the free state of not contacting the first fixed plate 111 and the second fixed plate 112 to abut against one of the first fixed plate 111 and the second fixed plate 112, so as to limit the relative movement between the pressing member 140 and the first fixed plate 111 and the second fixed plate 112.

[0046] In some examples, refer to Figure 3 , the moving plate can also be composed of only Figure 3 The upper part of the middle movable plate 120 and the lower part thereof are the pressing member, the movable plate and the pressing member are connected to each other, and the pressing member is raised toward the first fixed plate or the second fixed plate in whole or in part. The first fixed plate 111 or the second fixed plate 112 is provided with an avoidance position, so that in the initial position, the pressing member 140 does not contact the first fixed plate 111 or the second fixed plate 112, when in the initial position, the movable plate is located between the first fixed plate 111 and the second fixed plate 112, and the pressing member is in a free state without contacting the first fixed plate 111 and the second fixed plate 112, when the movable plate moves from the initial position to the unlocking position, the pressing member moves upward and switches to abut against one of the first fixed plate 111 and the second fixed plate 112, so as to limit the relative movement between the movable plate and the first fixed plate 111 and the second fixed plate 112. In this embodiment, the pressing member can be a partially or entirely planar structure, and the friction contact surface between it and the first fixed plate 111 or the second fixed plate 112 is larger. Preferably, a slope is provided between the movable plate and the pressing member to smooth the transition. More preferably, the movable plate and the pressing member are made of metal material, and the movable plate and the pressing member are integrally formed and bent.

[0047] For example, reference Figure 1 as well as Figures 4 to 6, the first fixed plate 111 and the second fixed plate 112 are parallel to each other and spaced apart. The movable plate 120 is movably arranged between the first fixed plate 111 and the second fixed plate 112, and the pressing member 140 is arranged on the movable plate 120 and is located on the side of the movable plate 120 opposite to the first fixed plate 111. In the direction along the thickness of the movable plate 120, the thickness of the pressing member 140 is slightly greater than the distance between the movable plate 120 and the first fixed plate 111. It can be understood that when the movable plate 120 moves upward to the unlocking position, the pressing member 140 will press against the first fixed plate 111, and the first fixed plate 111 will generate a friction force in the vertical direction on the movable plate 120, preventing the movable plate 120 from moving relative to the first fixed plate 111, so that the movable plate 120 can be fixed in the unlocking position.

[0048] In some embodiments, the fixed plate assembly 110 includes a fixing portion 113, and the movable plate 120 is provided with a guide groove 120d, which is in an elongated shape and arranged along the moving direction of the movable plate 120, and the fixing portion 113 passes through the guide groove 120d to limit the moving stroke of the movable plate 120 along the moving direction.

[0049] For example, reference Figure 4 and Figure 7 , a fixing portion 113 is provided between the first fixed plate 111 and the second fixed plate 112, and the two ends of the fixing portion 113 are respectively fixedly connected to the two fixed plates, so that the first fixed plate 111 and the second fixed plate 112 remain parallel to each other. In this embodiment, the fixing portion 113 includes a plurality of pins, and four pins are provided between the first fixed plate 111 and the second fixed plate 112. The movable plate 120 is provided with two long strip-shaped guide grooves 120d, and each guide groove 120d is provided along the up-down direction. Two of the four pins correspond to the lower sides of the two fixed plates, one corresponds to the upper sides of the two fixed plates, and the other corresponds to the relatively middle position of the two fixed plates. Each pin passes through a guide groove 120d, so the movable plate 120 can be lifted and moved between the two fixed plates under the limiting action of the guide groove 120d. The width of the guide groove 120d is slightly larger than the diameter of the pin shaft to ensure that the movable plate 120 will not get stuck when moving, and at the same time, the movable plate 120 will not have too much freedom in the horizontal direction, so that the movable plate 120 can move in the vertical direction as much as possible. The fixing portion 113 moves between the two ends of the guide groove 120d relative to the guide groove 120d. It can be understood that the length of the guide groove 120d is approximately equal to the moving stroke of the movable plate 120, ensuring that the movable plate 120 will not move excessively in the up and down directions.

[0050] In this embodiment, the pin can be easily installed and has a good fixing effect. In other embodiments, the fixing portion 113 can also be other parts such as screws.

[0051] In some embodiments, the movable plate 120 is provided with a convex shaft 121, and the convex shaft 121 is provided on a side of the movable plate 120 away from the second fixed plate 112. Figure 1 , Figure 2 and Fig. 9 , illustratively, the convex shaft 121 is vertically arranged on the surface of the movable plate 120, and the first fixed plate 111 is provided with a through slot 111a corresponding to the convex shaft 121, the through slot 111a is in a long strip shape and arranged in the up-down direction, and the convex shaft 121 extends from the through slot 111a in a direction away from the second fixed plate 112. When the movable plate 120 is in the initial position, after the driving lock 130 rotates counterclockwise for a certain distance, the push lock portion 131 contacts the convex shaft 121, and the driving lock 130 continues to rotate counterclockwise, and the push lock portion 131 pushes the convex shaft 121 upward from the bottom side of the convex shaft 121, so as to drive the movable plate 120 to move upward until it is in the unlocking position.

[0052] In some embodiments, the pressing member 140 includes a boss 141, which is arranged on the side of the movable plate 120 opposite to the first fixed plate 111; the drawer front panel fixing mechanism 100 also includes a support block 1141, which is arranged between the first fixed plate 111 and the second fixed plate 112, and the end of the support block 1141 away from the second fixed plate 112 is supported on the side of the movable plate 120 away from the first boss 141.

[0053] For example, reference Figure 1 , Figure 4 , Figure 6 and Figure 7 , a third fixed plate 114 is also provided on the side of the second fixed plate 112 facing away from the first fixed plate 111, and the bottom of the third fixed plate 114 is bent ninety degrees to bend to the horizontal direction. When the bottom of the third fixed plate 114 is placed flat on a horizontal plane, the first fixed plate 111 and the second fixed plate 112 are both in a vertically arranged state. The third fixed plate 114 is enclosed with the first fixed plate 111 and the second fixed plate 112 to form a slot extending in the horizontal direction for the plug 200 to be inserted. The slot can ensure that the plug 200 can only be inserted or removed in the horizontal direction. The third fixed plate 114 is provided with four limit buckles 1121, and each limit buckle 1121 corresponds to a corner of the third fixed plate 114. The four limit buckles 1121 make the third fixed plate 114 fit the second fixed plate 112. A support block 1141 is provided on one side of the second fixed plate 112 facing the first fixed plate 111, and the support block 1141 shortens the distance between the second fixed plate 112 and the first fixed plate 111. The support block 1141 extends from the second fixed plate 112 toward the movable plate 120, and supports the movable plate 120 from the side away from the first fixed plate 111, so that when the movable plate 120 moves, it will not be displaced toward the second fixed plate 112. Preferably, the support block 1141 includes a plurality of support blocks to support the movable plate 120 from a plurality of different positions.

[0054] Specifically, Figure 4 Part of the support block 1141 is formed by bending the outer edge of the second fixed plate 112 upward. In addition, the height of the groove wall constituting the slot is reduced, and is also formed by bending the inner side of the second fixed plate 112 upward, and the inner side height of the groove wall is reduced to form the support block 1141.

[0055] The pressing member 140 is a boss 141 provided on the movable plate 120, and the boss 141 is cylindrical and is located on one side of the movable plate 120 facing the first fixed plate 111. It can be understood that when the movable plate 120 moves upward, the boss 141 presses against the first fixed plate 111, so that the part of the movable plate 120 where the boss 141 is provided generates a force to move the movable plate 120 toward the second fixed plate 112 in the direction where the second fixed plate 112 is located. Since a support block 1141 is provided on the side of the movable plate 120 away from the first fixed plate 111, the support block 1141 supports the movable plate 120 so that 120 does not move significantly, so that the movable plate 120 is slightly deformed, so that the boss 141 is stuck between the first fixed plate 111 and the movable plate 120, and the movable plate 120 is stuck between the first fixed plate 111 and the second fixed plate 112. In this embodiment, when the unlocking member 130 rotates counterclockwise and drives the movable plate 120 to move upward to the unlocking position, the boss 141 presses against the first fixed plate 111, and a friction force is generated between the side of the movable plate 120 facing the first fixed plate 111 and the first fixed plate 111, and a friction force is generated between the side of the movable plate 120 facing the second fixed plate 112 and the support block 1141. The sum of the two friction forces is sufficient to offset the gravity of the movable plate 120, so that the movable plate 120 can be in a stationary state. When the plug 200 is inserted into the slot and abuts against the guiding bevel 120c, the vertical downward component force provided by the plug 200 to the movable plate 120 can be greater than the sum of the two friction forces, so that the movable plate 120 moves downward. Therefore, the plug 200 can drive the movable plate 120 to move from the unlocking position to the initial position.

[0056] In other examples, the support block 1141 may also be an elastic member disposed between the movable plate 120 and the second fixed plate 112. If the distance between the movable plate 120 and the second fixed plate 112 is closer, or the height of the boss 141 is high enough, the support block 1141 may not be disposed.

[0057] In some embodiments, the outer surface of the boss 141 is provided with a rounded chamfer or an oblique chamfer. Figure 6, illustratively, the outer circumferential side of the boss 141 is chamfered. In the present embodiment, a circular chamfer is processed along the outer circumferential side of the boss 141. When the movable plate 120 moves from the initial position to the unlocking position, the outer circumferential side of the boss 141 is pressed against the first fixed plate 111. The circular chamfer processed on the outer circumferential side of the boss 141 plays a guiding role, which significantly reduces the sense of sticking, so that the boss 141 can smoothly enter between the first fixed plate 111 and the second fixed plate 112, avoiding the outer circumferential side of the boss 141 and the first fixed plate 111 from blocking each other from moving toward each other, causing the movable plate 120 to be unable to move smoothly to the unlocking position.

[0058] In some embodiments, the movable plate 120 is made of a metal material, and the boss 141 is integrally formed with the movable plate 120. Exemplarily, the movable plate 120 is a metal plate, which can be made of a metal such as iron, copper, aluminum, etc., which can generate a large restoring force when slightly deformed, so as to more tightly press the boss 141 between the first fixed plate 111 and the second fixed plate 112. In this embodiment, the boss 141 is formed by stamping part of the movable plate 120 toward the first fixed plate 111. This processing method has low cost, and the boss 141 will not be separated from the movable plate 120, which is conducive to long-term use. In other embodiments, the boss 141 can also be a metal block, which is fixedly connected to the movable plate 120 by screwing or bonding.

[0059] In some embodiments, one of the first fixed plate 111 and the second fixed plate 112 is provided with a clearance groove 111b, and the clearance groove 111b is an arc groove with the rotation axis of the lock 130 as the center; the lock 130 also includes a first pin shaft 132, and the first pin shaft 132 is located in the clearance groove 111b. When the lock 130 rotates, the first pin shaft 132 moves in the clearance groove 111b; when the lock 130 rotates, the first pin shaft 132 moves in the clearance groove 111b; the first contact portion 122 is provided at the edge of the movable plate 120, and the length direction of the first contact portion 122 is parallel to the moving direction of the movable plate 120. The first contact portion 122 is used to contact with the first pin shaft 132 when the movable plate 120 is in the unlocked position to maintain the position of the lock 130.

[0060] For example, reference Figure 3 , Fig. 9 and Fig.10The rotation axis of the lock 130 is rotatably connected to the first fixed plate 111. With the rotation axis as the center of the circle, the first fixed plate 111 is formed with an arc-shaped air-avoiding groove 111b, which occupies about a quarter of the circumference. A first pin 132 is provided on the side of the lock 130 facing the second fixed plate 112. The first pin 132 passes through the air-avoiding groove 111b. When the lock 130 rotates, the first pin 132 can move between the two ends of the air-avoiding groove 111b. The first contact portion 122 is provided at the edge of the movable plate 120, and the first contact portion 122 is provided along the vertical direction.

[0061] It can be understood that when the lock 130 rotates upward, the convex shaft 121 is pressed by the push lock portion 131, so that the lock 130 can drive the movable plate 120 to move upward. When the movable plate 120 moves to the unlocking position, the first contact portion 122 just corresponds to the first pin 132 in the horizontal direction. At this time, the lock 130 has a tendency to rotate downward and reset under the drive of the reset member 150, so that the first pin 132 presses on the first contact portion 122. However, the boss 141 has pressed against the first fixed plate 111, so that the movable plate 120 is fixed by friction, and this friction is sufficient to offset the gravity of the movable plate 120 and the pressure applied by the first pin 132 to the first contact portion 122. Therefore, when the movable plate 120 is fixed in the unlocked position, the rotational position of the locking element 130 can also be fixed, and will not be affected by the resetting tendency of the locking element 130. Thus, the plug 200 can be removed from the slot at any time without worrying that the locking element 130 drives the movable plate 120 to reset and the plug 200 cannot be removed.

[0062] In this embodiment, the first contact portion 122 is a vertical edge surface of the side edge of the movable plate 120, whose vertical direction is parallel to the moving direction of the movable plate 120, and the first pin 132 is pressed against the edge surface. In other embodiments, the first contact portion 122 can also be a long strip of plastic or metal block arranged in the vertical direction and bonded to the edge of the movable plate 120.

[0063] In some embodiments, the lock element 130 is provided with a cross groove 133 or a straight groove, and the cross groove 133 or the straight groove and the first pin shaft 132 are respectively located on two sides of the rotation axis of the lock element 130 .

[0064] For example, reference Figure 8, a cross slot 133 is provided on one side of the lock 130. When the lock 130 needs to be rotated, a cross screwdriver can be inserted into the cross slot 133, and the lock 130 can be turned using the cross screwdriver, which is simple and labor-saving. The cross slot 133 and the first pin 132 are respectively located on both sides of the rotation axis of the lock 130. When the movable plate 120 is driven to move from the initial position to the unlocked position, the lock 130 is driven to rotate ninety degrees by the cross screwdriver, and the cross slot 133 rotates from the left side of the rotation axis to the lower side, which is more in line with the force application habit. In other embodiments, a slotted groove can also be provided on one side of the lock 130, and a slotted screwdriver can be inserted into the slotted groove to turn the lock 130.

[0065] In some embodiments, one end of the push lock portion 131 is connected to the rotation axis of the lock element, and the other end is connected to the reset element 150. Figure 8 The push lock portion 131 is a swing arm 1311, one end of which is connected to the rotation axis of the lock member 130, and the other end is connected to the reset member 150, and the swing arm 1311 corresponds to the convex shaft 121. When the movable plate 120 is located at the initial position, after the lock member 130 is driven to rotate counterclockwise for a certain distance, the swing arm 1311 contacts the convex shaft 121, and the lock member 130 is driven to continue to rotate counterclockwise, and the swing arm 1311 pushes the convex shaft 121 upward from the bottom side of the convex shaft 121, so as to drive the movable plate 120 to move upward until it is located at the unlocking position.

[0066] In some embodiments, the movable plate 120 is also provided with a second contact portion 123, the second contact portion 123 is located at the edge of the movable plate 120, and the second contact portion 123 and the first contact portion 122 are interconnected and arranged at an angle. When the movable plate 120 moves from the unlocking position to the initial position, the first pin shaft 132 changes from abutting against the first contact portion 122 to abutting against the second contact portion 123, and drives the movable plate 120 to move to the initial position.

[0067] For example, reference Figure 3 , Fig. 9 and Fig.10, the second contact portion 123 is also arranged at the edge of the movable plate 120, and one end of the second contact portion 123 is connected to the upper end of the first contact portion 122. When the movable plate 120 moves from the unlocked position to the initial position, the contact position between the first pin shaft 132 and the first contact portion 122 gradually moves upward until it contacts the intersection of the first contact portion 122 and the second contact portion 123, and then contacts the second contact portion 123. Since the second contact portion 123 is arranged at an angle with the first contact portion 122, when the first pin shaft 132 contacts the second contact portion 123, the first pin shaft 132 provides a component force in a downward direction to the second contact portion 123, so as to drive the movable plate 120 to move to the initial position. After long-term storage or use, the drawer front panel fixing mechanism 100 may be insufficiently lubricated or the movable plate 120 may be rusted, resulting in jamming of the movable plate 120 when moving up and down. By providing a second contact portion 123 that is arranged at an angle to the first contact portion 122, the lock element 130 can also drive the movable plate 120 to move to the initial position during the reset process driven by the reset element 150, thereby helping the movable plate 120 to return to the initial position, reducing the jamming feeling and further improving the user experience.

[0068] In this embodiment, similar to the first contact portion 122, the second contact portion 123 is also a section of the edge surface of the side edge of the moving plate 120. In other embodiments, the first contact portion 122 may also be a long strip of plastic or metal block bonded to the edge of the moving plate 120.

[0069] In some embodiments, an end of the second contact portion 123 away from the first contact portion 122 is higher than an end of the second contact portion 123 connected to the first contact portion 122 , so that the angle between the second contact portion 123 and the first contact portion 122 is an obtuse angle.

[0070] For example, continue to refer to Figure 3 , Fig. 9 and Fig.10 , the end of the second contact portion 123 away from the first contact portion 122 is higher than the end of the second contact portion 123 connected to the first contact portion 122. Therefore, when the first pin shaft 132 changes from abutting against the first contact portion 122 to abutting against the second contact portion 123, the first pin shaft 132 changes from moving upward relative to the movable plate 120 to moving obliquely upward, and the transition is smoother, which reduces the impact force of the first pin shaft 132 on the second contact portion 123, and avoids the first pin shaft 132 and the second contact portion 123 from colliding and reducing the durability of the drawer front panel fixing mechanism 100.

[0071] The present application also provides a drawer installation device, comprising a plug 200 and the above-mentioned drawer front panel fixing mechanism 100. Figure 3 and Fig.11, the plug 200 includes a plug shell 210, a plug box 230 and an adjusting screw 240. The plug box 230 is fixedly arranged between two plug pieces that are opposite and spaced apart. The plug box 230 is provided with an inner hole 230a along the thickness direction of the movable plate 120, and the plug shell 210 is provided with a through hole 210a corresponding to the inner hole 230a. When the plug 200 is inserted into the slot, the adjusting screw 240 is nested in the inner hole 230a through one of the through holes 210a. In this embodiment, the adjusting screw 240 is nested in the inner hole 230a to be threadedly connected with the plug box 230.

[0072] In this embodiment, the side of the plug 200 away from the abutment column 220 is fixedly connected to the drawer front panel (not shown), and the drawer front panel fixing mechanism 100 is connected to the drawer side panel (not shown).

[0073] The effect of using the adjusting screw 240 is as follows: Figure 4 and Fig.11 , screw the adjusting screw 240. Since the plug box 230 is limited by the slot, screwing the adjusting screw 240 can make the plug box 230 move in the slot along the axial direction of the adjusting screw 240, that is, the position of the plug 200 can be fine-tuned along the thickness direction of the movable plate 120. Therefore, the relative position of the drawer front panel and the drawer side panel in the length direction of the drawer front panel can be adjusted by screwing the adjusting screw 240 to offset the processing error of the drawer front panel and the drawer side panel in the horizontal direction, thereby improving the assembly rate between the drawer front panel and the drawer side panel.

[0074] The drawer front panel fixing mechanism 100 further includes an eccentric bolt 250, referring to Figure 1 , the eccentric bolt 250 is passed through the first fixed plate 111 and the second fixed plate 112, and the eccentric end of the eccentric bolt 250 is inserted into the third fixed plate 114. The third fixed plate 114 is preset with a movable groove, so that the eccentric end can move along the length direction of the movable groove. It can be understood that by using a screwdriver to rotate the eccentric bolt 250, the fixed plate assembly 110 can be moved up and down relative to the third fixed plate 114, that is, the slot can be moved up and down relative to the third fixed plate 114. Therefore, the insertion height of the plug 200 is adjustable, and then the relative position of the drawer front panel and the drawer side panel in the vertical direction can be adjusted by screwing the eccentric bolt 250 to offset the processing error of the drawer front panel and the drawer side panel in the vertical direction, thereby improving the assembly success rate between the drawer front panel and the drawer side panel.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
