Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge base disassembly and assembly structure. Background Art

[0002] A hinge is a mechanical device used to connect two solid parts and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more often installed on cabinet furniture.

[0003] When installing the hinge on the cabinet, the base on the hinge is tightly attached to the cabinet, and then the base is fixed to the cabinet by screws, bolts and other fixing parts to complete the installation of the hinge. However, in the prior art, the hinge arm and the base of the hinge are mostly integral structures, and the hinge arm is easy to block the fixation of the base, which makes the hinge installation inconvenient. Therefore, in view of the above technical problems, a hinge base disassembly and assembly structure is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a hinge base disassembly and assembly structure to prevent the hinge arm from blocking the base when the base is fixed, and facilitate the installation of the hinge.

[0006] A base, wherein the base is provided with a clamping block;

[0007] A hinge arm, comprising a first end portion and a second end portion opposite to each other, wherein the first end portion of the hinge arm is provided with a hook which is clamped on the bottom surface of the base; and

[0008] A separation buckle is installed on the second end of the hinge arm and is used to be clamped with the base. The separation buckle includes a buckle block and an elastic member. The buckle block is rotatably installed on the second end. A positioning portion abutting the second end and a clamping groove clamped with the clamping block are respectively provided on both sides of the rotation center of the buckle block. The elastic member connects the second end and the buckle block to keep the positioning portion abutting the second end.

[0009] The beneficial effects of the above hinge base disassembly and assembly structure are:

[0010] By rotating the snap block, the snap block rotates to separate the snap groove from the snap block, and the positioning portion from the second end, while pressurizing the elastic member. After the snap groove is separated from the snap block, the base can be moved to separate the base from the hook, thereby removing the base from the hinge arm. The base and the hinge arm are detachably connected to avoid obstruction of the hinge arm to the fixation of the base when the base is fixed to the cabinet. After the base is fixed to the cabinet, the hinge arm is moved to make the hook on the hinge arm clamped on the base, and the force applied to the snap block is cancelled. At this time, the reaction force of the elastic member can make the snap block rotate in the opposite direction, and the snap block rotates in the opposite direction to make the snap groove clamped with the snap block, and the positioning portion abuts against the second end, thereby fixing the hinge arm on the base, thereby completing the installation of the hinge, and the hinge is convenient to install.

[0011] In one embodiment, the bottom surface of the base is provided with a hook groove recessed toward the hinge arm, and the hook is locked in the hook groove. By providing the hook groove recessed toward the hinge arm, when the base is fixed on the cabinet, a gap is formed between the hook groove and the cabinet, which facilitates the hook to be locked in the hook groove, and the hook and the hook groove are easily engaged.

[0012] In one embodiment, the hooks and the hook grooves are arranged in two groups opposite to each other, thereby improving the stability of the connection between the first end of the hinge arm and the base.

[0013] In one embodiment, one group of the second end and the buckle block is provided with a positioning groove, and the other group is provided with a positioning block, one end of the elastic member abuts against the side wall of the positioning groove, and the other end is sleeved on the positioning block. By providing the positioning block to limit the elastic member, it is convenient to keep the elastic member in the correct position when the buckle block is rotated to squeeze the elastic member, and the elastic member can be removed by separating the elastic member from the positioning block, which is convenient for replacement of the elastic member.

[0014] In one embodiment, the buckle block is further provided with a toggle portion extending out of the second end portion for an operator to toggle, so that the buckle block can be driven to rotate by the toggle portion, and the buckle block can be rotated conveniently and labor-savingly.

[0015] In one embodiment, a plurality of anti-slip strips are evenly arranged on the outer side of the toggle portion. The anti-slip strips can prevent the operator from slipping when toggling the toggle portion to rotate the buckle block.

[0016] In one embodiment, the buckle block includes multiple groups of steel sheets, and the multiple groups of steel sheets are stacked to improve the strength of the buckle block, thereby increasing the service life of the buckle block.

[0017] In one embodiment, two sets of first limit blocks are arranged opposite to each other on the base, and the two sets of first limit blocks can extend into the inner cavity of the hinge arm, and the faces away from each other of the two sets of first limit blocks are in contact with the opposite faces of the inner cavity of the hinge arm. By arranging the two sets of first limit blocks in contact with the opposite faces of the inner cavity of the hinge arm, displacement of the base relative to the width direction of the hinge arm can be avoided, and the stability of the connection between the hinge arm and the base can be further improved.

[0018] In one embodiment, two sets of second limit blocks are arranged on the hinge arm in a relative manner, and the base is provided with limit slots corresponding to the two sets of second limit blocks, and the two sets of second limit blocks can be inserted into the two sets of limit slots. By setting the two sets of second limit blocks to be inserted into the two sets of limit slots, displacement of the base relative to the length direction of the hinge arm can be avoided, and the stability of the connection between the hinge arm and the base can be further improved.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0029] See also Figure 1 , Figure 3 , Figure 5 In one embodiment, a hinge base disassembly and assembly structure includes a base 10, a hinge arm 20 and a separation buckle.

[0030] The base 10 is provided with a clamping block 101 . The hinge arm 20 includes a first end portion and a second end portion opposite to each other. The first end portion of the hinge arm 20 is provided with a clamping hook 201 clamped on the bottom surface of the base 10 .

[0031] Specifically, the bottom surface of the base 10 is provided with a hook groove 104 which is recessed toward the hinge arm 20, and the hook 201 is clamped in the hook groove 104. Further, the hook 201 and the hook groove 104 are both provided in two groups opposite to each other.

[0032] In the above embodiment, by providing the hook groove 104 that is recessed toward the hinge arm 20, when the base 10 contacts the cabinet, a gap can be formed between the hook groove 104 and the cabinet, so that the hook 201 can be easily engaged with the hook groove 104. Moreover, the two groups of hooks 201 are engaged with the hook groove 104, which can improve the stability of the engagement between the first end of the hinge arm 20 and the base 10.

[0033] See also Figures 1 to 4 In one embodiment, the separation buckle is installed on the second end of the hinge arm 20 for being clamped with the base 10. The separation buckle includes a buckle block 202 and an elastic member 203. The buckle block 202 is rotatably installed on the second end. A positioning portion 204 abutting against the second end and a clamping groove 205 clamped with the clamping block 101 are respectively provided on both sides of the rotation center of the buckle block 202. The elastic member 203 connects the second end and the buckle block 202 for keeping the positioning portion 204 abutting against the second end.

[0034] Further, one group of the second end and the buckle block 202 is provided with a positioning groove 207, and the other group is provided with a positioning block 208. One end of the elastic member 203 abuts against the side wall of the positioning groove 207, and the other end is sleeved on the positioning block 208. Specifically in this embodiment, the elastic member 203 is a spring.

[0035] Furthermore, the buckle block 202 includes multiple sets of steel sheets, and the multiple sets of steel sheets are stacked.

[0036] In the above embodiment, by rotating the buckle block 202, the buckle block 202 rotates to separate the clamping groove 205 from the clamping block 101, the positioning portion 204 from the second end, and the elastic member 203 is compressed at the same time. After the clamping groove 205 is separated from the clamping block 101, the base 10 can be moved to separate the base 10 from the hook 201, so that the base 10 is removed from the hinge arm 20. The base 10 and the hinge arm 20 are detachably connected, so as to avoid the fixing of the base 10 by the hinge arm 20 when the base 10 is fixed to the cabinet. The base 10 is fixed on the cabinet, and then the hinge arm 20 is moved so that the hook 201 on the hinge arm 20 is locked on the base 10, and the force applied to the buckle block 202 is cancelled. At this time, the reaction force of the elastic member 203 can make the buckle block 202 rotate in the opposite direction, and the buckle block 202 rotates in the opposite direction to make the engaging groove 205 engage with the block 101, and the positioning portion 204 abuts against the second end, so that the hinge arm 20 is fixed on the base 10, and the installation of the hinge is completed, which is convenient for installing the hinge.

[0037] At the same time, by setting the positioning portion 204 to abut against the second end, the snap block 202 can be prevented from applying a continuous squeezing force to the snap block 101, thereby preventing the snap block 202 from continuously squeezing the snap block 101 and causing the snap block 101 to deform. The snap block 202 is formed by stacking multiple groups of steel sheets, which can improve the strength of the snap block 202, thereby improving the service life of the snap block 202.

[0038] See also Figures 2 to 4 In one embodiment, the buckle block 202 is further provided with a toggle portion 206 extending out of the second end for the operator to toggle. Further, a plurality of anti-slip strips 2021 are evenly arranged on the outer side of the toggle portion 206.

[0039] In the above embodiment, the toggle portion 206 is provided to facilitate the buckle block 202 to rotate, and the buckle block 202 is rotated conveniently and labor-savingly. The anti-slip strip 2021 is provided to avoid slipping when the toggle portion 206 is toggled.

[0040] See also Figure 2 , Figure 4 , Figure 5 In one embodiment, two sets of first limit blocks 102 are arranged opposite to each other on the base 10 , and the two sets of first limit blocks 102 can extend into the inner cavity of the hinge arm 20 , and the facing surfaces of the two sets of first limit blocks 102 are in contact with the opposite surfaces of the inner cavity of the hinge arm 20 .

[0041] Furthermore, two groups of second limit blocks 209 are relatively arranged on the hinge arm 20 , and the base 10 is provided with limit slots 103 corresponding to the two groups of second limit blocks 209 , and the two groups of second limit blocks 209 can be inserted into the two groups of limit slots 103 .

[0042] In the above embodiment, by setting two groups of first limit blocks 102 in contact with the opposite surfaces of the inner cavity of the hinge arm 20, the base 10 can be prevented from being displaced in the width direction of the hinge arm 20. By setting two groups of second limit blocks 209 penetrating into the two groups of limit grooves 103, the base 10 can be prevented from being displaced in the length direction of the hinge arm 20, thereby improving the stability of the connection between the base 10 and the hinge arm 20.

[0043] The specific implementation of the above hinge base disassembly and assembly structure is as follows:

[0044] When installing the hinge, first, the snap block 202 is rotated by toggling the toggle portion 206. The snap block 202 rotates to separate the snap groove 205 from the snap block 101, and the positioning portion 204 is separated from the second end portion. At the same time, the elastic member 203 is compressed. After the snap groove 205 is separated from the snap block 101, the base 10 can be moved to separate the first limit block 102 from the inner cavity of the hinge arm 20, and the second limit block 209 is separated from the limit groove 103, and the hook 201 is separated from the hook groove 104, so that the base 10 is removed from the hinge arm 20. The base 10 and the hinge arm 20 are detachably connected to avoid the hinge arm 20 blocking the fixation of the base 10 when the base 10 is fixed to the cabinet. After the base 10 is fixed on the cabinet, the hinge arm 20 is moved so that the hook 201 on the hinge arm 20 is locked in the hook groove 104, and the two groups of first limit blocks 102 extend into the inner cavity of the hinge arm 20 and contact the opposite surface of the inner cavity of the hinge arm 20. The second limit block 209 is inserted into the limit groove 103, and then the force applied to the toggle part 206 is canceled. At this time, the reaction force of the elastic member 203 can make the buckle block 202 rotate in the opposite direction. The buckle block 202 rotates in the opposite direction to make the engaging groove 205 engage with the block 101, and the positioning part 204 abuts against the second end, so that the hinge arm 20 is fixed on the base 10, and the installation of the hinge is completed, which is convenient for installing the hinge.

[0045] At the same time, by setting two groups of first limit blocks 102 in contact with the opposite surfaces of the inner cavity of the hinge arm 20, the base 10 can be prevented from being displaced in the width direction of the hinge arm 20. By setting two groups of second limit blocks 209 passing through the two groups of limit grooves 103, the base 10 can be prevented from being displaced in the length direction of the hinge arm 20, thereby improving the stability of the connection between the base 10 and the hinge arm 20.
