[0011] At the bend of the support hook plate near the keel frame, a secondary connecting plate is provided on the side of the hook plate away from the bend of the hook plate. The secondary connecting plate is provided with a connecting plate, and the secondary connecting plate abuts against the connecting plate. The connecting plate is provided with a sliding plate, which is parallel to the hook plate and fits against the side of the keel frame. The two sides of the sliding plate pass between two sets of support hook plates of another vertical keel frame that need to be connected.

[0015] The beneficial effects of this utility model are as follows: This utility model is a quick-installation adjustable floor support frame that can be adjusted in height, fixed, and quickly assembled and disassembled. Its specific implementation method is as follows:

[0016] The operator first inserts the clamping block in the height adjustment bracket through the two sets of support hook plates from the left and right sides, so that the snap block abuts against the biting teeth and forms a cavity with the horizontal fixed plate to wrap around the bending part of the support hook plate for fixation. Then, the height adjustment nut is inserted between the anti-detachment plate and the thrust plate. Then, the end of the threaded rod with the fixed through hole is inserted through the thrust plate and rotated to connect to the height adjustment nut. The clamping block clamps the height adjustment nut to prevent it from rotating and completes the fixation. Then, the middle of the threaded rod is rotated to fix a nut and the fixed round plate is rotated to the end away from the fixed through hole. The fixed nut is rotated to abut against the fixed round plate to prevent the support platform from falling off. When adjusting the height, the distance between the height adjustment nut and the support platform can be adjusted to complete the height adjustment function. The fixed through hole at the top can be connected to the panel or floor tile to be supported through the through hole on the support plate to prevent the floor tile from shifting.

[0017] Since a single keel frame is prone to tipping and shifting, it can be horizontally fixed using fasteners: After two sets of sliding plates are symmetrically inserted between the two sets of support hook plates from the left and right sides, the bend on the lower hook plate wraps around and fastens to the bend of the support hook plate on the other keel frame. Then, the connecting nail passes through the through hole and connects the connecting through hole, bringing the secondary connecting plate and the connecting plate closer together. After the clamping cover plate abuts and engages, the support hook plate of the keel frame held by the sliding plate abuts against the support plate of the keel frame with the height adjustment bracket below, thus achieving fixation. At the same time, when the two sets of keels are close to each other, the outer support plate abuts against the bend of the upper support hook plate to complete the support. The connecting plate and the secondary connecting plate can abut or not abut depending on the support length of the support hook plate.

[0018] After the above fixation is completed, the two sides of the fixed circular plate are then fastened by the fixing notch on the fixing plate, and screws are inserted through the limiting through hole on the bending fixing plate to achieve fixation, so as to prevent the keel frame from sliding and shifting due to external force.

[0019] The equipment has a simple structure and can be quickly disassembled and assembled, as well as provide lateral support. It also solves the problem of height adjustment, making it practical and economical, which is beneficial for the promotion and use of the equipment. Attached Figure Description

[0031] The following is combined Figure 1-7 This invention describes a specific embodiment of a quick-install adjustable floor support frame, comprising:

[0032] The keel frame includes a support plate 1, and support hook plates 11 are provided on both sides of the support plate 1. The cross-section of the support hook plates 11 has a "J" shaped structure. Specifically, each bend is preferably a right angle for easy manufacturing. The two sets of support hook plates 11 are arranged opposite and symmetrically at the bends. The support plate 1 is fixedly connected to the side of the support hook plates 11 away from the bends. The side of the support hook plates 11 away from the support plate 1 is provided with several biting teeth 111 for abutting the contact surface. Preferably, they can be notched teeth.

[0033] The height adjustment bracket 2 is positioned between two sets of support hook plates 11. The height adjustment bracket 2 includes a thrust plate 21, which is parallel to the support plate 1 and abuts against the support hook plates 11. Lateral fixing plates 22 are provided on both sides of the thrust plate 21. Two sets of clamping blocks 23 are provided in the middle of the thrust plate 21. The clamping blocks 23 clamp the bends of the support hook plates 11 between themselves and the adjacent lateral fixing plates 22. A latching block 24 is provided on the side of the clamping block 23 away from the thrust plate 21, and an anti-detachment plate 25 is provided on the side of the clamping block 23 away from the lateral fixing plates 22. The anti-detachment plate 25 is parallel to the support plate 1, and the latching block 24 is parallel to the thrust plate 21. The latching block 24 abuts against the engaging teeth 111. The force plate 21 is provided with a height adjustment rod between the two sets of clamping blocks 23 to adjust the parallel distance between the force plate 21 and the support plane. The height adjustment rod includes a threaded rod 26, which passes through and extends through the middle of the force plate 21. A support platform 27 is provided on the side of the threaded rod 26 away from the support plate 1. A fixed circular plate 271 is provided on the top surface of the support platform 27. The threaded rod 26 passes through the fixed circular plate 271 and is rotatably connected to the support platform 27. A height adjustment nut 281 and a fixed nut 28 are provided in the middle of the threaded rod 26. The fixed nut 28 abuts against the fixed circular plate 271. The height adjustment nut 281 is inserted between the two sets of anti-detachment plates 25 and the force plate 21. The two sets of clamping blocks 23 clamp the height adjustment nut 281.

[0034] In practice, the end of the threaded rod 26 with the fixed through hole 261 is then passed through the thrust plate 21 and rotated to the height adjustment nut 281. The clamping block 23 clamps the height adjustment nut 281 to prevent it from rotating and thus completing the fixation. Then, the middle of the threaded rod 26 is rotated by a fixing nut 28, and the fixing round plate 271 is rotated to the end away from the fixed through hole 261. The fixing nut 28 is then rotated to abut against the fixing round plate 271 to prevent the support platform 27 from falling off. When adjusting the height, the distance between the height adjustment nut 281 and the support platform 27 can be adjusted to complete the height adjustment function.

[0035] Beneficially, the support plate 1 has several through holes 12 in the middle, and the through holes 12 are arranged in a linear array on the support plate 1. The threaded rod 26 has a fixing through hole 261 at the end away from the support platform 27, which is used to assist the fixing rod in connecting to the fixing through hole 261 through the through hole 12. The fixing through hole 261 is a countersunk hole; or a threaded hole; or a polygonal hole. The attached figure shows a threaded hole, which can be used to connect screws.

[0036] Beneficially, the keel frame is also equipped with a fixing fastener 3, which is used to connect another keel frame perpendicular to the axis of the supporting plate 1, thereby strengthening the fixation of the two sets of keel frames. The fixing fastener 3 includes two sets of hook plates 35, which are symmetrically arranged and have a "J" shape. The opposite sides of the two sets of hook plates 35 abut against the sides of the adjacent keel frames. The bends of the hook plates 35 are parallel to and abut against the bends of the adjacent supporting hook plates 11 of the keel frame. The hook plates 35 are far away from the hooks. A secondary connecting plate 34 is provided on one side of the bend of the connecting plate 35. A connecting plate 32 is provided on the secondary connecting plate 34. The secondary connecting plate 34 abuts against the connecting plate 32. A sliding plate 31 is provided on the connecting plate 32. The sliding plate 31 is parallel to the hook plate 35 and fits against the side of the keel frame. The two sides of the sliding plate 31 pass between the two sets of support hook plates 11 of the other vertical keel frame that need to be connected. A clamping cover plate 311 is also provided on the sliding plate 31. The clamping cover plate 311 abuts against the interlocking teeth 111 of the two adjacent sets of support hook plates 11.

[0037] Beneficially, the side of the secondary connecting plate 34 away from the hook plate 35 is provided with an outer support plate 33, which is used to abut against the side of the vertically connected keel frame support hook plate 11 away from the support plate 1.

[0038] Beneficially, the secondary connecting plate 34 is also provided with several connecting through holes 341, which are symmetrically arranged in two in the attached figure. The actual situation can be determined according to the actual situation. The connecting plate 32 is provided with a through hole 321 on the projection side of the connecting through hole 341 on the secondary connecting plate 34, which is the same as the axis of the connecting through hole 341. The fixing fastener 3 also includes several connecting nails 36. The connecting nails 36 pass through the through hole 321 and are rotatably connected to the connecting through hole 341.

[0039] Beneficially, fixing plates 29 are also provided on both sides of the fixing circular plate 271. Fixing recesses 291 are provided on the opposite sides of the two sets of fixing plates 29. The fixing plates 29 abut against the support platform 27. A bent fixing plate 292 is provided on the side of the fixing plate 29 away from the fixing recesses 291. The fixing recesses 291 have an "L" shaped structure. Several limiting through holes 293 are provided on the bent fixing plate 292. The axis of the limiting through holes 293 is perpendicular to the support plane of the support platform 27.

[0040] Working principle of this utility model:

[0041] The operator first inserts the clamping block 23 in the height adjustment bracket 2 directly into the two sets of support hook plates 11 from both sides, so that the snap-on block 24 abuts against the engagement teeth 111 and forms a cavity with the transverse fixing plate 22 to wrap around the bend of the support hook plate 11 for fixation. Then, the height adjustment nut 281 is inserted between the anti-detachment plate 25 and the thrust plate 21. Then, the end of the threaded rod 26 with the fixing through hole 261 is inserted through the thrust plate 21 and rotated to connect to the height adjustment nut 281. The clamping block 23 clamps the height adjustment nut 281 to prevent it from slipping off. After the height adjustment nut 281 is rotated to fix it, the middle of the threaded rod 26 is rotated by another fixing nut 28, and then the fixing round plate 271 is rotated to the end away from the fixing through hole 261. The fixing nut 28 is rotated to abut against the fixing round plate 271, which can prevent the support platform 27 from falling off. When adjusting the height, the distance between the height adjustment nut 281 and the support platform 27 can be adjusted to complete the height adjustment function. The fixing through hole 261 at the top can be connected to the panel or floor tile to be supported through the through hole 12 on the support plate 1 to prevent the floor tile from shifting.

[0042] Since a single set of keel frames is prone to tipping and shifting, it can be horizontally fixed by fixing fasteners 3: After two sets of sliding plates 31 are symmetrically inserted between the two sets of support hook plates 11 from the left and right sides, the bend on the hook plate 35 below wraps around and fastens the bend of the support hook plate 11 on the other set of keel frames. Then, the connecting nail 36 passes through the through hole 321 and connects to the connecting through hole 341, so that the secondary connecting plate 34 and the connecting plate 32 are close to each other. After the clamping cover plate 311 abuts and engages, the support hook plate 11 of the keel frame clamped by the sliding plate 31 abuts against the support plate 1 of the keel frame with the height adjustment bracket 2 below, thus achieving fixation. At the same time, when the two sets of keel frames are close to each other, the outer support plate 33 abuts against the bend of the support hook plate 11 of the upper support to complete the support. The connecting plate 32 and the secondary connecting plate 34 can abut or not abut according to the support length of the support hook plate 11.

[0043] After the above fixing is completed, the fixing recess 291 on the fixing plate 29 is used to fasten the two sides of the fixing round plate 271. Then, screws are inserted through the limiting through hole 293 on the bending fixing plate 292 to achieve fixing, so as to prevent the keel frame from sliding and shifting due to external force.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
