Description

[Technical Field]

[0001] This utility model relates to a shelf support component inside a freezer. [Background Technology]

[0002] Generally, freezers (refrigerators, refrigerators, etc.) use shelves to hold items. Inside the freezer, multiple mounting plates are installed, with sliders on these plates to support the shelves. Multiple spaced-apart positioning parts on the mounting plates support the sliders, allowing them to move up and down. The sliders engage with different positioning parts, thus adjusting their height. Locking blocks on the sliders secure the shelves, allowing them to be positioned in various locations. Currently, there is a shelf support column on the market, similar to patent number 202320583232.9, titled "A Simplified Shelf Buckle Assembly." Its second positioning part is located on an elastic wall, and both the slider support and shelf locking rely on the elastic wall. While simple, the slider's support strength and the reliability of the locking height need improvement. [Utility Model Content]

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a buckle with a simple structure, secure locking of shelves and support blocks, and easy height locking.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A height-locking buckle includes a mounting plate fixed to the inner wall of a freezer. A support block is slidably provided on the mounting plate along its length. Multiple support portions are provided along the length of the mounting plate. A support groove with an upper opening for inserting a shelf is provided on the support block. The support groove is formed by a bottom wall and a first side wall and a second side wall spaced apart from each other. The first side wall extends vertically and is located on the side of the support block near the mounting plate. An elastic latch is provided at the rear of the first side wall. A positioning portion that can engage with the support portion is provided on the elastic wall. A first latch that can cover the opening of the support groove to lock the shelf and a second latch that can engage with the first latch to keep it locked are rotatably provided on the first side wall. The elastic wall is characterized by having an abutment portion that, when the positioning portion is engaged with the support portion and the second latch engages with the first latch, abuts against the second latch, thereby blocking the elastic wall and preventing the positioning portion from disengaging from the support portion.

[0006] As described above, a buckle that facilitates height locking is characterized in that: the first buckle is provided with a buckle protrusion for the second buckle to engage, the abutment part is a boss, and the second buckle is provided with an abutment protrusion that abuts against the boss.

[0007] As described above, a buckle that facilitates height locking is characterized in that: when the first buckle and the second buckle are engaged, the second buckle is engaged on one side of the buckle protrusion, and the second buckle, the abutment protrusion, and the boss are located on the same side of the buckle protrusion.

[0008] The buckle described above, which facilitates locking the height, is characterized in that: the boss is provided with an inclined surface that provides clearance for the second buckle to rotate and unlock.

[0009] The buckle described above, which facilitates height locking, is characterized in that: the top of the elastic lever wall is provided with an arc-shaped lever extending toward one side of the second side wall.

[0010] As described above, a buckle that facilitates height locking is characterized in that: the positioning part and the abutment part are respectively provided on the rear side and the front side of the elastic lever wall.

[0011] As described above, a buckle that facilitates height locking is characterized in that: the first sidewall is provided with an inclined wall extending vertically; the second buckle includes an insertion end that can be rotatably inserted into the support block; an elastic pressing edge that can slide downward along the inclined wall and be squeezed and deformed by the inclined wall when the second buckle rotates to lock the first buckle; and a locking edge that can lock with the second buckle; when the first buckle is moved to unlock the first buckle and the second buckle, the elastic pressing edge restores its deformation and, under the action of elastic force, causes the second buckle to rotate upward and reset.

[0012] The buckle described above, which facilitates height locking, is characterized in that: two oppositely spaced insertion protrusions are provided on the front end face of the first sidewall; the two ends of the first buckle and the second buckle are respectively rotatably inserted into the two insertion protrusions; the elastic wall is provided between the two insertion protrusions; the inclined wall is an inclined edge provided on at least one insertion protrusion; and the inclined wall gradually inclines outward from the bottom end to the top end towards the outside of the support block.

[0013] The buckle described above, which facilitates height locking, is characterized in that: the insertion boss is provided with a positioning groove for the elastic pressing edge to engage after the second buckle is rotated upwards and reset.

[0014] The buckle described above, which facilitates height locking, is characterized in that: the inclined wall is provided on the opposite side of the two insertion bosses, two elastic pressing edges are provided corresponding to the inclined wall, the two elastic pressing edges are respectively provided at both ends of the snap-fit ​​edge, and the insertion end is provided at the end of each of the two elastic pressing edges.

[0015] The buckle described above, which facilitates height locking, is characterized in that: the support portion is a protrusion or a support hole.

[0016] The beneficial effects of this utility model are as follows: A first and second latch are rotatably mounted on the support block, with the first and second latches engaging against each other. This results in a large locking force. During locking, the abutment part on the elastic wall abuts against the second latch. Because the second latch engages with the first latch, when the shelf is locked, the second latch is positioned by the first latch, while the elastic wall is positioned by the first latch. The locking force between the second and first latches provides support for the elastic wall during locking, effectively preventing deformation and thus preventing the positioning part from detaching from the support part, thereby improving the support strength of the elastic wall. The second latch has an elastic pressing edge. During locking, the elastic pressing edge moves downwards along the inclined wall, and the inclined wall presses against the elastic pressing edge, giving it a certain... With a certain elastic force, when the first latch is moved so that it is no longer stuck with the second latch, the elastic pressing edge recovers its deformation under the action of the elastic restoring force. The elastic pressing edge will move upward along the inclined wall, thereby driving the second latch to rotate upward and reset, thus achieving automatic release. Compared with pressing down on the second latch from below to make it elastically reset, the second latch relies on bending force to reset, which makes the second latch prone to bending. After being locked for a long time, the second latch may be deformed and unable to reset. However, with the pressing action of the inclined wall, the reset of the second latch does not rely entirely on bending deformation force, thereby reducing the bending deformation of the second latch and increasing its service life. By setting a positioning groove, the second latch is kept in the unlocked state, so as not to interfere with the picking and placing of the shelf. [Attached Image Description]

Detailed Implementation Methods

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0024] Example 1, as Figures 1 to 5As shown, a height-locking buckle includes a mounting plate 1 fixed to the inner wall of a freezer. The mounting plate 1 is vertically fixed, and a support block 2 is slidably provided on the mounting plate 1 along the length of the mounting plate. Multiple support portions 3 are provided on the mounting plate 1 along its length. The support portions 3 are protrusions or support holes; in this embodiment, the support portions 3 are protrusions. The support block 2 has a support groove 21 with an upper opening for inserting a shelf. The support groove 21 is open at its upper end and is surrounded by a bottom wall 12, a first side wall 11, and a second side wall 13 spaced apart from each other. The first side wall 11 extends vertically and is located on the side of the support block 2 closest to the mounting plate 1. The side closest to the mounting plate 1 is defined as the rear side, and the side furthest from the mounting plate 1 is defined as the front side. The rear of the first side wall 11 is provided with an elastic sliding wall 14, which is located in the middle of the first side wall 11. A window is provided in the middle of the first side wall 11, and the elastic sliding wall 14 extends vertically and is located inside the window. The bottom of the elastic sliding wall 14 is connected to the bottom of the first side wall 11 or the bottom wall 12, and the other sides of the elastic sliding wall 14 are separated from the window. The elastic wall 14 is provided with a positioning part 4 that can be locked onto the support part 3. The positioning part 4 presses against the upper end face of the protrusion of the support part 3. The first side wall 11 is rotatably provided with a first latch 5 that can cover the opening of the support groove 21 to lock the shelf, and a second latch 6 that can be rotatably provided to lock the first latch 5 and keep the first latch 5 locked. When locked, the second latch 6 is on top and the first latch 5 is on the bottom, and the second latch 6 and the first latch 5 form a certain angle. The elastic wall 14 is provided with abutting part 15, which can abut against the second locking 6 when the positioning part 4 is engaged with the support part 3 and the second locking 6 is engaged with the first locking 5, thereby blocking the elastic wall 14 and preventing the positioning part 4 from disengaging from the support part 3. The positioning part 4 and the abutting part 15 are respectively provided on the rear side and the front side of the elastic wall 14. The elastic wall 14 can be supported by the abutting part 15 abutting against the second locking 6, and the support strength of the elastic wall 14 is improved, which can prevent the positioning part 4 from disengaging from the support part 3. This support is obtained by the second locking 6 locking with the first locking 5. This structure is simple and easy to operate. The support force of the support block 2 can rely on the locking force of the second locking 6 and the first locking 5, and the support strength is high.

[0025] To facilitate locking, the first latch 5 has a latching protrusion 51 for the second latch 6 to latch. The latching protrusion 51 is upwardly protruding and formed by bending. The abutment part 15 is a boss. The second latch 6 has an abutment protrusion 61 that abuts against the boss. The abutment protrusion 61 is formed by bending. When the first latch 5 and the second latch 6 are latched, the second latch 6 is locked on the rear side of the latching protrusion 51 (the side closer to the mounting piece 1). The second latch 6, the abutment protrusion 61, and the boss are located on the same side of the latching protrusion 51. The second latch 6 can prevent the elastic wall 14 from deforming forward. To prevent the boss from interfering with the second latch 6, the boss has an inclined surface 16 that provides clearance for the second latch 6 to rotate and unlock. The inclined surface 16 slopes forward and downward from top to bottom, so that the second latch 6 will not jam with the boss during the rotation and unlocking process. For ease of operation, the top of the elastic lever wall 14 is provided with an arc-shaped lever 17 extending toward the second side wall 13. When the arc-shaped lever 17 is moved to the rear, the positioning part 4 can be moved away from the support part 3.

[0026] To enable the second latch 6 to automatically reset, the first sidewall 11 is provided with a vertically extending inclined wall 18. The second latch 6 includes a plug-in end 62 that can be rotatably inserted into the support block 2, an elastic pressing edge 63 that can slide downward along the inclined wall 18 and be squeezed and deformed by the inclined wall 18 when the second latch 6 rotates to lock the first latch 5, and a locking edge 64 that can lock with the second latch 26. Both the first latch 5 and the second latch 6 are bent rods. When the first latch 5 is moved to unlock the first latch 5 from the second latch 6, the elastic pressing edge 63 recovers its deformation and, under the action of elastic force, causes the second latch 6 to rotate upward and reset. When rotating from the unlocked state to the locked state, the elastic pressing edge 62 will move downward along the inclined wall 18. Under the action of the inclined wall 18, the elastic pressing edge 62 is squeezed and deformed. When the second latch 6 is in the locked state, the elastic pressing edge 62 is squeezed against the inclined wall 18. The squeezing force F on the elastic pressing edge 62 (see schematic diagram) Figure 5 (As shown) The mechanism is decomposed into an upward rotating force F1 and a horizontal contracting force F2. When the first latch 5 is turned, it releases the second latch 6. Under the action of the upward rotating force F1, the second latch 6 rotates upward, and the horizontal contracting force F2 causes the elastic pressing edge 62 to elastically reset towards the inclined wall 18, thus causing the second latch 6 to rotate upward and reset along the inclined wall 18. When the first latch 5 is turned to unlock the second latch 6, the elastic pressing edge 62 recovers its deformation and, under the action of the elastic force, rotates upward along the inclined wall 18, causing the second latch 6 to rotate upward and reset, thus achieving automatic unlocking. The structure is simple and easy to use.

[0027] For ease of installation, the front end face of the first sidewall 11 is provided with two oppositely spaced insertion bosses 19. The two ends of the first latch 5 and the second latch 6 are respectively rotatably inserted into the two insertion bosses 19. The insertion bosses 19 are provided with insertion holes, and the ends of the first latch 5 and the second latch 6 are inserted into the insertion holes. An elastic wall 14 is provided between the two insertion bosses 19. An inclined wall 18 is an inclined edge provided on at least one insertion boss 19. The inclined wall 18 gradually inclines outward from the bottom to the top of the support block 2. The insertion bosses 19 are provided with positioning grooves 65 for the elastic pressing edge 63 to engage after the second latch 6 rotates upward and resets. The positioning groove 65 is at the top of the inclined wall 18. After the elastic pressing edge 62 elastically resets to one side of the inclined wall 18, it enters the positioning groove 65. This supports the second latch 6 and prevents it from tilting downward, thereby preventing interference with the shelf placement. Inclined wall 18 is provided on the opposite side of two plug-in protrusions 19. Two elastic extrusion edges 63 are provided in one-to-one correspondence with inclined wall 18. The two elastic extrusion edges 63 are respectively provided at both ends of snap-fit ​​edge 64. The plug-in end 62 is provided at the end of each of the two elastic extrusion edges 63.

[0028] Example 2, as Figure 6 The difference from Embodiment 1 is that in this embodiment, the support part 3 is a support hole, and the positioning part 4 is inserted into the support hole for positioning.

[0029] The above description, in conjunction with specific preferred technical solutions, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this utility model, and all such modifications or substitutions should be considered within the scope of protection of this utility model.
