[0006] The center of the transverse profile has a first transverse channel running through both ends. The middle parts of the four outer side walls of the profile distributed in a rectangle all have a first connection groove extending horizontally and concavely. First side hole groups are provided at both ends of the transverse profile. The first side hole group has a first longitudinal channel and a first vertical channel passing through both sides, and the first longitudinal channel passes through the first connection grooves on both longitudinal sides of the profile, and the first vertical channel passes through the first connection grooves on both vertical sides of the profile.

Specifically, the transverse profile 1 has a first hollow cavity 15 inside. The first transverse channel 11 is spaced in the first hollow cavity 15.

The second mounting shaft hole 211 is perpendicular to the first mounting shaft hole 231. And an inwardly concave insertion area 24 is formed between one end of the middle body 21 and the connecting parts 22 on both sides.

[0044] The center of the vertical profile 3 has a second vertical channel 31 running through both ends. At the middle of both ends of the vertical profile 3, there are second connecting blocks 32 protruding for insertion into the first connecting grooves 12.

[0046] Moreover, the insertion areas 24 of the longitudinal profiles 2 forming the upper rectangular frame face upward and are used for the protrusions on the top plate to insert; The insertion areas 24 of the longitudinal profiles 2 forming the lower rectangular frame face downward and are used for the protrusions on the bottom plate to insert.

[0047] Assembling various profiles of the present utility model into a three-dimensional frame is more convenient and the structure is more stable. When the profiles are assembled with each other, two first connecting blocks 23 on the longitudinal profile 2 are respectively inserted into the first connecting grooves 12 of the lateral profiles 1 distributed front and back on both sides, and the first connecting piece passes through the first longitudinal channel 13 in the front-back direction and is inserted into the first mounting shaft hole 231, thereby fixing the two profiles;

[0048] The second connecting blocks 32 at both ends of the vertical profile 3 are respectively inserted into the first connecting grooves 12 of the upper and lower lateral profiles 1, and the second connecting piece passes through the first vertical channel 14 in the up-down direction and is inserted into the second vertical channel 31, thereby fixing the two profiles. When the profiles are connected, the force is evenly distributed and the overall structure is firm;

[0049] After assembling into a three-dimensional frame, plates are covered outside the entire frame to form a cabinet. The plates are also connected to the profiles by screwing. The second grooves on the vertical profiles can also be engaged with the protrusions on the peripheral plates.

The insertion areas on the lower longitudinal profiles can also be engaged with the protrusions on the bottom plates.

[0050] Specifically, it further includes a longitudinal reinforcement profile 4 and a transverse reinforcement profile 5 connected to the middle parts of the two vertical profiles 3. The longitudinal reinforcement profile 4 also has two first connecting blocks 23 and first mounting shaft holes 231 on both sides. When the profiles are assembled with each other, the two first connecting blocks 23 on the longitudinal reinforcement profile 4 are respectively inserted into the second connecting grooves 34 of the vertical profiles 3 on the front and back sides, and the first mounting shaft holes 231 and the second longitudinal channels 35 are in communication for passing through the first connecting piece. The first connecting piece passes through the second longitudinal channel 35 in the front-back direction and is inserted into the first mounting shaft hole 231, thereby fixing the two profiles;

[0051] The center of the horizontal reinforcement profile 5 also has a first horizontal channel 11 running through both ends, and third connection blocks 51 protrude from the middle parts of both ends thereof. When the profiles are assembled with each other, the third connection blocks 51 at both ends of the horizontal reinforcement profile 5 are respectively inserted into the second connection grooves 34 of the vertical profiles 3 at the left and right ends, and the first horizontal channel 11 and the second horizontal channel 36 are in communication for passing through a third connecting member, and the third connecting member passes through the first horizontal channel 11 in the left-right direction and is fitted into the second horizontal channel 36.

[0053] Specifically, the other end of the middle body 21 on the longitudinal reinforcement profile 4 also protrudes outward relative to the two side connection parts 22, and it is used to be inserted into the groove on the side plate.

[0054] The above-mentioned connecting members can be screws, bolts, etc.

[0055] The present utility model can also reinforce the overall frame by adding the longitudinal reinforcement profile 4 and the horizontal reinforcement profile 5. Since the longitudinal reinforcement profile 4 has the same structure as the longitudinal profile 2, the two can be used interchangeably, and can be used both for connecting the horizontal profiles 1 and for connecting the middle parts of the vertical profiles 3. When the longitudinal reinforcement profile 4 is laterally installed on the vertical profile 3, the protruding middle body 21 faces left or right, which is convenient for inserting into the groove of the side plate, and screws are driven into the second mounting shaft hole 211 for fixation, making the connection more firm; and the insertion area 24 can be used for the protrusions of other plates or profiles to be inserted. The splicing methods are diverse and are not limited to being placed in one orientation.

[0056] The horizontal profile or the vertical profile is integrally rectangular, so that the contact surface has a relatively large stress surface during splicing and erection, which can improve the strength and stability of the profile, and can connect other profiles in all four directions for multi-directional connection.

[0057] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two components or the interaction relationship between two components.
