A new type of left and right adjustment mechanism for the panel

Abstract

The present invention discloses a novel left - right adjustment mechanism for a panel, which includes an upper cover, a panel pin assembly, and a fixed seat. The panel pin assembly is horizontally and slidably inserted into the fixed seat. An adjustment screw for restricting the left - right sliding position of the panel pin assembly is provided at the sliding insertion joint between the panel pin assembly and the fixed seat. When the adjustment screw is downward and in contact with the top panel of the fixed seat, there is a reserved thread of half a turn to one turn at the top of the adjustment screw to engage with the internal thread of the plate screw hole. When the adjustment screw is upward and in contact with the inner bottom surface of the upper cover, there is a reserved thread of half a turn to one turn at the bottom of the adjustment screw to engage with the internal thread of the plate screw hole. Smooth sections indicating no threads are reserved at the top and bottom of the adjustment screw. The adjustment screw set in the present invention has a shorter thread length, which can prevent the adjustment screw from completely falling off, improve the problem that the original adjustment structure easily deforms the upper cover and the fixed seat, and prevent the threads from being damaged.

Description

Technical Field

[0001] The invention specifically relates to a drawer left-right adjustment mechanism, in particular to a novel panel left-right adjustment mechanism. Background Art

[0002] When using the existing left and right adjusting screws to adjust the left and right positions of the straight drawer, after the adjusting screws are rotated to the specified limit position, they can still be turned vigorously, causing the position of the panel latch to exceed the designed adjustable range. The adjusting screws and the panel latches will exert pressure on the upper cover and the fixing seat, causing deformation of the upper cover and the fixing seat and damage to the threads of the adjusting screws, which may cause the adjustment function to fail or the parts to be irreversibly deformed and damaged.

[0003] Therefore, in response to this type of problem, we need a drawer left and right position adjustment mechanism that can protect the fixing base, the upper cover and the screws themselves. Summary of the invention

[0004] The object of the present invention is to provide a novel panel left-right adjustment mechanism to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A novel panel left-right adjustment mechanism comprises an upper cover, a panel latch assembly and a fixing seat, wherein the fixing seat is laterally slidably plugged with a panel latch assembly that can slide left-right, and an adjusting screw for limiting the left-right sliding position of the panel latch assembly is provided at the sliding plugging position of the panel latch assembly and the fixing seat, and the panel of the fixing seat is covered with a fixed upper cover, and the upper cover and the top surface of the fixing seat enclose a main adjustment sliding slot opening facing the side wall of the fixing seat, and the panel latch assembly comprises a latch main connecting rod for fixing to the drawer, and a main adjustment latch plate for inserting into the main adjustment sliding slot is fixed on the rod wall of the latch main connecting rod, A plate screw hole is vertically penetrated through the main adjustment pin plate, and an adjusting screw is mounted on the inner thread of the plate screw hole. A cover screw hole is reserved on the top surface of the upper cover for rotating the adjusting screw. When the adjusting screw is downwardly connected to the top panel of the fixing seat, a half-circle to a full-circle thread is reserved at the top of the adjusting screw for connecting with the inner thread of the plate screw hole. When the adjusting screw is upwardly connected to the inner bottom surface of the upper cover, a half-circle to a full-circle thread is reserved at the bottom of the adjusting screw for connecting with the inner thread of the plate screw hole. The thread of the adjusting screw is arranged on the outer wall of the middle part of the adjusting screw, and smooth sections indicating no threads are reserved at the top and bottom of the adjusting screw.

[0007] As a further solution of the present invention: A lower cover is snap-fitted and covered on the top surface of the fixed seat. The lower cover and the fixed seat are covered with an auxiliary sliding slot opening parallel to the main adjustment sliding slot opening. An auxiliary plug plate is slidably inserted into the auxiliary sliding slot. The auxiliary plug plate is fixed on the side wall of one side of the plug main connecting rod that is the same as the plate screw hole.

[0008] As a further solution of the present invention: A rivet for passing through the lower cover and the upper cover for limiting is vertically fixed on the fixed seat. Limit holes opposite to the position of the rivet are opened on the lower cover and the upper cover.

[0009] As a further solution of the present invention: The opening length of the cover screw hole along the sliding direction of the panel plug assembly in the main adjustment sliding slot opening is greater than the top diameter of the adjustment screw, and the opening width of the cover screw hole is less than the top diameter of the adjustment screw.

[0010] Compared with the prior art, the beneficial effect of the present invention is: The adjustment screw provided by the present invention has a shorter thread length. While not causing the adjustment screw to fall off completely, it improves the problem that the original adjustment structure easily deforms the upper cover and the fixed seat, and prevents the thread from being damaged.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figures 1 to 4, in the embodiment of the present invention, a novel left - right adjustment mechanism for a panel includes an upper cover 2, a panel pin assembly 3, and a fixed seat 4. The panel pin assembly 3 that can slide left and right is horizontally and slidably inserted into the fixed seat 4. At the sliding insertion part of the panel pin assembly 3 and the fixed seat 4, an adjustment screw 33 is provided for restricting the left - right sliding position of the panel pin assembly 3. The upper cover 2 is fixedly covered on the panel of the fixed seat 4. The upper cover 2 and the top surface of the fixed seat 4 enclose a main adjustment sliding notch 11 with an opening facing the side wall of the fixed seat 4. The panel pin assembly 3 includes a pin main connecting rod 34 for installing and fixing with a drawer. A main adjustment pin plate 30 for inserting into the main adjustment sliding notch 11 is fixed on the rod wall of the pin main connecting rod 34. A plate screw hole 32 is vertically penetrated through the main adjustment pin plate 30. An adjustment screw 33 is threadedly sleeved in the plate screw hole 32. A cover screw hole 20 for rotating the adjustment screw 33 is reserved on the top surface of the upper cover 2. When the adjustment screw 33 is in contact with the top panel of the fixed seat 4 downward, half a turn to one turn of thread teeth are reserved at the top of the adjustment screw 33 for connection with the internal thread in the plate screw hole 32. When the adjustment screw 33 is in contact with the inner bottom surface of the upper cover 2 upward, half a turn to one turn of thread teeth are reserved at the bottom of the adjustment screw 33 for connection with the internal thread in the plate screw hole 32. The thread teeth of the adjustment screw 33 are opened on the outer side wall of the middle part of the adjustment screw 33. Smooth sections indicating no threads are reserved at the top and bottom of the adjustment screw 33. The smooth sections provided on the adjustment screw 33 mainly prevent the adjustment screw 33 from being disengaged from the plate screw hole 32. When the adjustment screw 33 presses downward against the top surface of the fixed seat 4, at this time, half a turn to one turn of thread teeth are reserved at the top of the adjustment screw 33. When the adjustment screw 33 moves to the bottom limit position, the adjustment screw 33 presses downward on the fixed seat 4 to cause a slight deformation. The deformation of the fixed seat 4 jacks up the adjustment screw 33. The adjustment screw 33 is tightly engaged in the plate screw hole 32. Even if it is further pressed downward until the adjustment screw 33 is no longer thread - connected with the plate screw hole 32, the smooth section at the top of the adjustment screw 33 can maintain the relative position between the adjustment screw 33 and the plate screw hole 32, ensuring that the adjustment screw 33 will not be disengaged from the plate screw hole 32. When the adjustment screw 33 slides and no longer applies pressure downward on the fixed seat 4, the fixed seat 4 no longer continues to deform. At the same time, the deformation of the fixed seat 4 will also jack up the adjustment screw 33, springing the adjustment screw 33 back into the plate screw hole 32, which is convenient for the adjustment screw 33 to be screwed out upward and aligned while protecting the thread teeth of the adjustment screw 33 from being deformed by pressure.

[0022] The opening length of the cover screw hole 20 along the sliding direction of the panel pin assembly 3 in the main adjustment sliding notch 11 is greater than the top diameter of the adjustment screw 33, and the opening width of the cover screw hole 20 is less than the top diameter of the adjustment screw 33. This is mainly to facilitate rotating the adjustment screw 33 to tighten or loosen it in the sliding direction and also to prevent the adjustment screw 33 from passing through upward from the cover screw hole 20.

[0023] The working principle of the present invention is as follows: When the drawer's left and right positions are adjusted by sliding the panel latch assembly 3 left and right on the fixed seat 4, when the adjusting screw 33 is tightened downward at the cover screw hole 20 and abuts against the top surface of the fixed seat 4, at this time, there is a half-turn to one turn of thread teeth reserved at the top end of the adjusting screw 33. When the adjusting screw 33 moves to the bottom limit position, the adjusting screw 33 presses downward on the fixed seat 4 to cause a slight deformation. The deformation of the fixed seat 4 pushes the adjusting screw 33 upward, and the adjusting screw 33 engages tightly in the plate screw hole 32. Even if it is further pressed downward until the adjusting screw 33 is no longer thread-connected to the plate screw hole 32, the smooth section at the top end of the adjusting screw 33 can maintain the relative position between the adjusting screw 33 and the plate screw hole 32, ensuring that the adjusting screw 33 will not become disengaged from the plate screw hole 32. The adjusting screw 33 slides and no longer applies pressure downward on the fixed seat 4, and the fixed seat 4 no longer continues to deform. At the same time, the deformation of the fixed seat 4 will also push the adjusting screw 33 upward, springing the adjusting screw 33 back into the plate screw hole 32, facilitating the upward screwing out of the adjusting screw 33 for alignment while protecting the thread teeth of the adjusting screw 33 from being compressed and deformed. Similarly, when the adjusting screw 33 is tightened upward and abuts against the inner bottom surface of the upper cover 2, at this time, there is a half-turn to one turn of thread teeth reserved at the bottom end of the adjusting screw 33. When the adjusting screw 33 moves to the top limit position, the slight elastic deformation of the upper cover 2 will press the adjusting screw 33 into the plate screw hole 32 to maintain the engaged state between the adjusting screw 33 and the plate screw hole 32. At this time, when the adjusting screw 33 is further rotated upward until it is no longer thread-connected to the plate screw hole 32, the adjusting screw 33 slides and no longer continues to move upward, protecting the upper cover 2 from further deformation. The smooth section at the bottom end of the adjusting screw 33 can maintain the relative position between the adjusting screw 33 and the plate screw hole 32, and the deformation of the upper cover 2 presses the adjusting screw 33 downward back into the plate screw hole 32, facilitating the downward screwing tight of the adjusting screw 33 for alignment while protecting the thread teeth of the adjusting screw 33 from being compressed and deformed.

[0024] Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is as follows:

[0026] A lower cover 1 is snap-fitted and covered on the top surface of the fixed seat 4. The lower cover 1 and the fixed seat 4 are covered with an auxiliary sliding slot 10 parallel to the main adjustment sliding slot 11. An auxiliary latch plate 31 is slidably inserted in the auxiliary sliding slot 10. The auxiliary latch plate 31 is fixed on the side wall of one side of the latch main connecting rod 34 that is the same as the plate screw hole 32. The arranged auxiliary latch plate 31 and the auxiliary sliding slot 10 can improve the stability and smoothness of the sliding insertion of the panel latch assembly 3 and the fixed seat 4.

[0027] A rivet 40 for passing through the lower cover 1 and the upper cover 2 for limiting is vertically fixed on the fixed seat 4. Limiting holes corresponding to the position of the rivet 40 are opened on the lower cover 1 and the upper cover 2.

[0028] On the panel side of the lower cover 1 located on one side of the latch panel assembly 3, two notches are provided. Vertical plates are fixedly arranged on the left and right sides of the opening direction of the notches. The upper cover 2 is sleeved on both sides of the vertical plates to form a main adjustment sliding notch 11.
