[0067] The suspended door and window frame material rack in the embodiment of the present application is as follows: Figure 1 , 2 As shown, it includes a main frame 1 provided with a sliding space;

[0068] A moving frame 2 is slidably mounted in the sliding space, wherein a first receiving space for receiving door and window frame materials is provided in the moving frame 2, and when the moving frame 2 slides to the uppermost end of the sliding space, a second receiving space for receiving door and window frame materials is formed below the moving frame 2 in the sliding space;

[0069] A limiting mechanism 3 is provided to connect the main frame 1 and the moving frame 2 to limit the moving frame 2.

[0070] In an embodiment of the present application, a sliding space is provided in the main frame 1, and a slidable movable frame 2 is provided in the sliding space; the movable frame 2 can slide in the main frame 1, and a first receiving space for storing door and window frame materials is provided in the movable frame 2; when the movable frame 2 slides to the uppermost end inside the sliding space, that is, the uppermost end inside the main frame 1, a second receiving space for storing door and window frame materials will be formed below the movable frame 2 in the sliding space, and a limiting mechanism 3 is provided between the main frame 1 and the movable frame 2, and the limiting mechanism 3 is used to limit the moving range of the movable frame 2.

[0071] A movable frame 2 is provided inside the main frame 1, which can increase the height of the rack while complying with ergonomics, thereby rationally utilizing the free space in the upper part of the truck compartment, improving the loading rate of the door and window frame racks, reducing transportation costs, and also reducing the number of racks and the frequency of handling.

[0072] The main frame 1 of the door and window frame material rack is a rectangular structure with four hollow sides, which is convenient for staff to operate the door and window frame materials. The positioning of the fixed part in the main frame 1 is designed according to the conventional structure. The main profile of the material rack adopts 40-3 square tube or 40×30-3 rectangular tube. On this basis, the column specifications in the main frame 1 are replaced with 40-4 square tubes to increase the structural strength and frame stability. The bottom of the door and window frame material rack is provided with a double-layer load-bearing structure to enhance the stability when loading door and window frame materials.

[0073] The main profile of the moving frame 2 is 30-2 square tube, which can effectively reduce the weight and size of the moving frame 2 when the strength is sufficient. The moving frame 2 is embedded in the main frame 1 and can slide up and down in the sliding space.

[0074] like Figure 1-3 As shown, in another embodiment, the mobile frame 2 includes a mobile upper frame 21, a mobile lower frame 22, and a support column 23 connected between the mobile upper frame 21 and the mobile lower frame 22, and the support column 23 is slidably connected to the main frame body 1;

[0075] A first receiving space is formed between the movable upper frame 21, the movable lower frame 22 and the support column 23;

[0076] A push rod 24 for pushing the moving frame 2 is also connected between the two support columns 23 .

[0077] In this embodiment, four support columns 23 are arranged between the movable upper shelf 21 and the movable upper shelf 21, and the support columns 23 can be slidably connected to the main frame 1. The first receiving space formed between the movable upper shelf 21, the movable lower shelf 22 and the support columns 23 can be divided into front and rear ends along the placement direction of the door and window frame materials. The two support columns 23 connected with the push rods 24 are the front support columns. The front end of the main frame is the main operating surface for the staff. The staff can unload or install the door and window frames in front of the main frame. After placing the door and window frame materials in the first receiving space, the staff can directly use the push rod 24 to push the movable frame 2 upwards, which is convenient for the staff to unload the door and window frame material rack.

[0078] In a preferred embodiment, a slide rail is respectively arranged between each support column 23 and the main frame body 1, and at least four movable bearings are arranged on each slide rail. The movable bearings are ball bearings, so that the movable frame 2 can move more flexibly in the sliding space, limiting the two translational degrees of freedom of the movable frame in the horizontal direction, thereby ensuring the stability of the movable frame 2 inside the main frame body 1.

[0079] like Figure 4 As shown, in another embodiment, the limiting mechanism 3 includes at least one self-elastic latch 31 disposed at the bottom of the movable lower frame 22 and at least one first pin hole 32 disposed on the main frame 1;

[0080] A main side beam 118 is disposed at the lowermost end of the sliding space. When the self-elastic latch 31 slides and contacts the main side beam 118 , it is triggered, and the self-elastic latch 31 pops out and extends into the first pin hole 32 .

[0081] In this embodiment, the self-elastic latch can adopt the self-elastic latch structure in the prior art. The specific structure of the self-elastic latch is not described in detail in this application. At least one self-elastic latch 31 is arranged at the bottom of the movable lower frame 22, at least one first pin hole 32 corresponding to the self-elastic latch 31 is arranged on the main frame 1, and a main side beam 118 is arranged at the bottom of the sliding space. When the self-elastic latch 31 slides to the lowest end in the sliding space, the trigger point of the self-elastic latch 31 will contact the main side beam 118 and be triggered, and the self-elastic latch 31 will pop out and extend into the first pin hole 32, thereby locking the movable frame 2 and limiting the moving range of the movable frame 2 inside the main frame 1. The movable frame 2 can be limited to move only inside the sliding space to prevent damage to the door and window frame material of the lower layer, and it is also more convenient to remove the door and window frame material in the first receiving space.

[0082] In a preferred embodiment, the movable lower frame 22 is provided with two self-elastic latches 31, and the main frame 1 is also correspondingly provided with two first pin holes 32. When the trigger points of the two self-elastic latches 31 respectively contact the two main side beams 118, the self-elastic latches 31 will extend into the two first pin holes 32 to lock the movable frame 2.

[0083] When the moving frame 2 needs to be unlocked, the staff needs to pull out the self-elastic latch 31 from the first pin hole 32 to unlock the moving frame 2 locked by the self-elastic latch 31 .

[0084] like Figure 5 As shown, in another embodiment, the limiting mechanism 3 further includes a clamping head assembly 33 disposed in the moving frame 2 and a second pin hole 34 disposed on the main frame body 1;

One end of the positioning pin bar 331 is movably connected to the movable lower frame 22, and the other end extends through the support column 23 toward the second pin hole 34. The positioning pin bar 331 is inserted into the second pin hole 34 to lock the movable frame 2.

[0086] In this embodiment, the clamp assembly 33 arranged in the movable frame 2 cooperates with the second pin hole 34 arranged on the main frame 1, wherein the clamp assembly 33 includes a positioning pin bar 331, and the positioning pin bar 331 is telescopically installed on the movable lower frame 22, and the positioning pin bar 331 and the second pin hole 34 are located on the same horizontal line, one end of the positioning pin bar 331 is movably connected to the movable lower frame 22, and the other end extends toward the second pin hole 34 through the support column 23. When the movable frame 2 is locked, the positioning pin bar 331 is inserted into the second pin hole 34 to complete the locking, and when the movable frame 2 needs to be moved, the positioning pin bar 331 is moved out of the second pin hole 34 to complete the unlocking.

[0087] The clamping head assembly 33 is provided with two second pin holes 34 at different heights on the same vertical line. Each positioning pin hole 34 corresponds to the uppermost and lowermost ends of the moving frame 2 in the sliding space. When the moving frame 2 slides to the lowest end in the sliding space, the positioning pin bar 331 can extend into the second pin hole 34 below to fix the moving frame 2. When the moving frame 2 slides to the uppermost end in the sliding space, the positioning pin bar 331 extends into the second pin hole 34 above to fix the moving frame 2.

[0088] like Figure 5 As shown, in a preferred embodiment, the clamp assembly 33 further includes a support 332 mounted on the movable lower frame 22 and a first magnetic steel seat 333, a second magnetic steel seat 334, an actuating rod 335 and a swing rod 336 mounted on the support 332;

The swing end 3362 swings between the first magnetic steel seat 333 and the second magnetic steel seat 334 and can be adsorbed on the first magnetic steel seat 333 and the second magnetic steel seat 334.

[0090] One end of the actuating rod 335 is rotatably connected to the positioning pin 331, and the other end is rotatably connected to the swing rod 336;

[0091] The swing rod 336 rotates around the fixed end 3361, driving the actuating rod 335 to move so as to push the positioning pin strip 331 to move telescopically in the horizontal direction.

[0092] In this preferred embodiment, the chuck assembly 33 includes a support 332, a first magnetic steel seat 333, a second magnetic steel seat 334, an actuating rod 335 and a swing rod 336, wherein the support 332 is arranged on the movable lower frame 22, the first magnetic steel seat 333, the second magnetic steel seat 334, the actuating rod 335 and the swing rod 336 are installed on the support 332, and the swing rod 336 includes a fixed end 3361 and a swing end 3362, the fixed end 3361 is rotatably installed on the support 332, and the swing end 3362 can swing between the first magnetic steel seat 333 and the second magnetic steel seat 334, and can also be adsorbed on the first magnetic steel seat 333 or the second magnetic steel seat 334.

[0093] One end of the actuating rod 335 is rotatably connected to the positioning pin bar 331, and the other end is rotatably connected to the swing rod 336. When the swing end 3362 swings between the first magnetic steel seat 333 and the second magnetic steel seat 334, the swing rod 336 rotates around the fixed end 3361, thereby driving the actuating rod 335 to actuate, and the actuating rod 335 pushes the positioning pin bar 331 to move telescopically in the horizontal direction.

[0094] Specifically, when the swing end 3362 is adsorbed on the first magnetic steel seat 333, the swing rod 336 will drive the actuating rod 335 to push the positioning pin 331 into the second pin hole 34 to lock the moving frame 2;

[0095] When the swing end 3362 is adsorbed on the second magnetic steel seat 334 , the swing rod 336 will drive the actuating rod 335 to push the positioning pin 331 out of the second pin hole 34 , thereby unlocking the movable frame 2 .

[0096] When the swing end 3362 is adsorbed on the first magnetic steel seat 333 or the second magnetic steel seat 334, the fixed end 3361 and the support 332 will reach a mechanical dead point, and it has a self-locking function. When the movable frame 2 needs to be unlocked or locked, the swing rod 336 can be manually controlled to swing between the first magnetic steel seat 333 and the second magnetic steel seat 334, which is convenient for the staff to operate and increases the structural safety of the door and window frame rack.

[0144] The first fixed lower frame 11 also includes a rotatable third clamping member 119, which includes a third clamping rod 1191 and two third connecting rods 1192 extending vertically from both ends of the third clamping rod 1191. The extended end of each third connecting rod 1192 is rotatably connected to a main side beam 118, and the third clamping rod 1191 is arranged parallel to the fifth lower support beam 151, the sixth lower support beam 152, the third upper support beam 115 and the third rear support beam 16.

[0145] In this embodiment, the third clamping member 119 is rotatably disposed on the first fixed lower frame 11, and the third clamping member 119 includes a third clamping rod 1191 and two third connecting rods 1192 extending vertically from both ends of the third clamping rod 1191, and the extended ends of the two third connecting rods 1192 are rotatably connected to the two main side beams 118, respectively, and the third clamping rod 1191 is arranged parallel to the fifth lower support beam 151, the sixth lower support beam 152, the third upper support beam 115 and the third rear support beam 16.

[0146] In this embodiment, the first fixed lower frame 11 further includes two second extension members extending vertically downward. When the third receiving space is loaded with door and window frame materials, the third pressing member 119 needs to fix the door and window frame materials. The two third connecting rods 1192 rotate, and the two ends of the third pressing rod 1191 are connected to the two second extension members, thereby fixing the door and window frame materials in the third receiving space.

[0147] When it is necessary to unload the door and window frame materials, the third clamping piece 119 will be rotated. At this time, the two third connecting rods 1192 are lifted upward, and the third clamping rod 1191 is driven into the first fixed lower frame 11. The third clamping piece 119 and the first fixed lower frame 11 are on the same horizontal plane, which is convenient for the staff to unload the door and window frame materials.

[0148] like Figure 7-11As shown, when the door and window frame material rack is empty, the movable frame is at the lowest end in the sliding space, which is convenient for the staff to carry out loading work. When the door and window frame materials need to be loaded, the door and window frame materials are first loaded into the first receiving space, and each door and window frame material is aligned and snapped into a first lower card slot 223, a second lower card slot 224, a first upper card slot 213 and a first rear card slot 26 at the same time. After the first receiving space is fully loaded, the first clamping rod is pressed down to abut against the door and window frame material, thereby fixing the door and window frame material in the first receiving space, and the staff then unlocks the self-elastic latch and the clamp assembly, and pushes the push rod to move the movable frame upward until it reaches the uppermost end in the sliding space for locking. After the movable frame 2 moves to the uppermost end in the sliding space, the clamping head assembly 33 locks the movable frame 2 again, and the staff can then fill the second receiving space. Each door and window frame material is aligned and inserted into a third lower slot 113, a fourth lower slot 114, a second upper slot 228 and a second rear slot 14 at the same time. After the second receiving space is fully loaded, the second clamping rod 2291 is pressed down to abut against the door and window frame material, thereby fixing the door and window frame material in the second receiving space.

[0149] After filling the second receiving space, the staff can fill the third receiving space. Each door and window frame material is aligned and inserted into a fifth lower slot 153, a sixth lower slot 154, a third upper slot 117 and a third rear slot 17 at the same time until the third receiving space is full. The third clamping rod is then pressed down to abut against the door and window frame material, thereby fixing the door and window frame material in the third receiving space.

[0150] When it is necessary to unload the fully loaded door and window frame rack, first lift the second clamping rod 2291 in the second receiving space to the same horizontal plane as the movable lower rack 22, then remove the door and window frame materials in the second receiving space, and then lift the third clamping rod in the third receiving space to the same horizontal plane as the first fixed lower rack, and then remove the door and window frame materials in the third receiving space.

[0151] Finally, the staff can remotely cancel the fixation of the clamp assembly 33 on the moving frame 2, and use the push rod 24 to move the moving frame 2 to the lowest point in the sliding space. At this time, the self-elastic pin 31 will slide to contact the main side beam 118 and be triggered by it. The self-elastic pin 31 pops out and extends into the first pin hole 32, thereby limiting the moving range of the moving frame 2 in the sliding space. The staff then inserts the positioning pin strip 331 in the clamp assembly 33 into the second pin hole 34 in the main frame body 1 to complete the locking of the moving frame 2 in the vertical direction.

[0152] After locking the movable frame 2, the staff can pull the first clamping rod 281 downward until the first clamping rod 281 and the movable lower frame 22 are at the same horizontal plane, and the door and window frame materials inside the first receiving space can be removed to complete the overall unloading.

[0153] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0154] The above description is only the principle and preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this field, the implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included in the technical scope of the present invention.
