Description

Technical Field

[0001] The invention relates to a cargo transfer rack, in particular to a cargo transfer rack used for train seats. Background Art

[0002] The existing train seats are all transported in paper boxes. Since the paper boxes may be damaged during the packaging, loading and unloading, transportation and disassembly process, and the existing paper boxes themselves do not have a stable structure, the existing paper boxes are disposable. Therefore, the transportation of paper boxes will increase the cost. At the same time, the blind and large-scale use of paper boxes is not conducive to environmental protection. In addition, since the existing paper boxes need to be placed on the fork frame before they can be transported by the forklift, and the excessive use of the fork frame will inevitably take up space, it is not conducive to the movement of the forklift and affect the loading and unloading efficiency. In addition to the above problems, the paper boxes are easy to deform, which may not only affect the stability of the stacked boxes, but also cause damage to the seats due to excessive pressure. Summary of the invention

[0003] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a transfer rack that can be recycled, is easy to load and unload, and can provide good protection for the seat.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a transfer frame for train seats, comprising a base frame that is generally rectangular and leg frames arranged on the front and rear sides of the base frame, and the leg frames are arranged upward; the base frame comprises a lower frame and an upper frame, and a gap is reserved between the lower frame and the upper frame; a plurality of limiting connectors are arranged at the front of the base frame, and the limiting connectors divide the reserved gap at the front of the base frame into two front fork holes; a limiting baffle is arranged on the side of the base frame, and the reserved gap on the side of the base frame is divided into two side fork holes, and the fork of a forklift can be inserted into the side fork holes to transport the entire transfer frame. A front locking member is arranged at the front of the chassis, and the front locking member includes a limiting pillow plate and a front pressing member. The limiting pillow plate is used to support the front support of the seat bottom support, and the front pressing member is used to press the front support; a rear locking member is arranged at the rear of the chassis, and the rear locking member includes a lining plate and a rear pressing member. The lining plate is used to support the rear support of the seat bottom support, and the rear pressing member is used to fix the rear support on the lining plate; each leg frame includes two vertical supporting legs, and a plug is arranged on one supporting leg, and a socket is arranged on the other supporting leg, so that the plugs of the two symmetrically placed transfer frames can be inserted into the socket. An angle positioning member is arranged at each of the four corners of the chassis, and the angle positioning member includes a shaft sleeve and an insertion shaft. When the entire transfer frame is placed upright, the lower end of the insertion shaft extends out of the shaft sleeve. When the two transfer frames are stacked back to back, the lower insertion shaft retracts into the shaft sleeve, and the upper insertion shaft is inserted into the lower shaft sleeve.

[0005] In the above technical solution, the chassis is used to place the seat support seat, and the front locking member and the rear locking member arranged thereon can respectively lock the front support and the rear support of the seat bottom support, thereby fixing the seat support seat on the chassis, and the leg frame arranged above the chassis forms a rectangular storage space for protecting the seat, and the two transfer frames can be stacked up and down for use, so that a protective space is formed between the two transfer frames. The side fork holes and the front fork holes arranged on the chassis 1 facilitate forklifts to transport the transfer frames. In this way, the use of an independent fork base can be omitted, which can save site space, and at the same time, the transfer frames can be transported more flexibly and quickly. When the two transfer frames are stacked back to back, the lower plug shaft is retracted into the shaft sleeve, and the upper plug shaft is inserted into the shaft sleeve below, so that the two chassis are fixed to each other, ensuring that the stacked transfer frames can remain stable.

[0006] Preferably, the front clamping member includes a clamping rod and a pre-tightening bolt. The clamping rod is provided with a waist-shaped hole that penetrates the clamping rod longitudinally. The pre-tightening bolt is installed on the base frame after longitudinally passing through the waist-shaped hole, and the clamping rod can be moved forward and backward under the restriction of the waist-shaped hole. Before the front support is placed on the limiting pillow plate, the clamping rod can be moved forward to avoid the front support. After the front support is placed, the clamping rod is pressed on the front support by moving the clamping rod backward. Since the clamping rod is always mounted on the pre-tightening bolt, there will be no loss of parts, ensuring that the transfer rack will not malfunction during the recycling process.

[0007] Preferably, the rear clamping member includes a pressure rod and a clamping bolt, wherein the pressure rod includes a rotating part and a contact and pressure part, the rotating part is installed on the base frame through an axle seat, and the contact and pressure part can be pressed on the lining plate by flipping; the clamping bolt is installed on the base frame, and a clamping head for clamping the contact and pressure part is arranged on the clamping bolt. In the process of placing the rear support on the lining plate, the pressure rod is flipped to avoid the rear support. After the rear support is placed on the lining plate, the pressure rod is flipped and pressed on the rear support. The pressure rod is operated by a simple position conversion, which is conducive to the rapid disassembly and assembly of the pressure rod. At the same time, the pressure rod is installed on the axle seat during the whole process to avoid the loss of the pressure rod during the recycling use of the transfer rack. Preferably, two sets of rear locking members are used, and the pressure rods of the two sets of rear locking members are independently fixed to the rear support. In this way, when one pressure rod is deformed, the other pressure rod can still play a fixing role.

[0008] Preferably, the leg frame is connected to the base frame in a foldable manner; a leg mounting sleeve is provided at each of the four corners of the base frame, a leg mounting cavity for mounting the leg frame is provided in the middle of the leg mounting sleeve, and the leg mounting cavity extends to the lower part of the base frame; limiting holes are provided on the left and right walls of the leg mounting sleeve, a limiting shaft that is movably clamped in the limiting hole is provided at the lower end of the leg frame, and a avoidance opening pointing to the rear is provided on the front leg mounting sleeve, and a avoidance opening pointing to the front is provided on the rear leg mounting sleeve, so that the leg frame can lie flat on the base frame after being moved upward and turned over, which can reduce the occupied space of the transfer frame and facilitate the transportation and storage of the transfer frame. In addition, the entire transfer frame includes two major parts: the leg frame and the base frame, wherein the base frame has a complex structure, and the leg frame needs to withstand huge pressure. When the leg frame is damaged, the entire transfer frame can be restored to its original function by replacing a new leg frame, which can reduce the scrap rate of the product. In addition, when two elastic pullers are provided for each leg frame, one end of the elastic puller is connected to the leg frame, and the other end is connected to the base frame. After the leg frame is folded, the elastic puller tightly pulls the leg frame, so that the folded transfer frame maintains the stability of each component.

[0009] Preferably, the transfer rack is equipped with a top frame, which includes four plug-in legs corresponding to the supporting legs one by one, and plugs and sockets are respectively arranged on the plug-in legs, so that the plug-in legs can be plugged into the leg rack. When the transfer rack loaded with seats is stacked in a single layer or an odd number of layers, the top frame cooperates with the uppermost transfer rack, so that a single transfer rack can also form a complete protection space.

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figure 1-6An embodiment of the present invention is a transfer rack for train seats, including a rectangular base frame 1 and leg frames 2 arranged on the front and rear sides of the base frame 1, and the leg frames 2 are arranged upward; wherein the base frame 1 includes a lower frame 7 and an upper frame 8, and a gap is reserved between the lower frame 7 and the upper frame 8; a plurality of limit connectors 10 are arranged at the front of the base frame 1, and the limit connectors 10 divide the reserved gap at the front of the base frame 1 into two front fork holes 12, and a limit baffle 15 is arranged on the side of the base frame 1, and the reserved gap on the side of the base frame 1 is divided into two side fork holes 11. The fork of a forklift can be inserted into the front fork hole 12 or the side fork hole 11 and carry the entire transfer rack. In this way, the use of an independent fork base can be eliminated, that is, the site space can be saved, and the transfer rack can be carried more flexibly and quickly.

[0026] A middle support rod frame 13 is arranged in the middle of the upper frame 8, and a front locking member 3 is arranged in the front, the front locking member 3 includes a limiting pillow plate 31 and a front pressing member, the limiting pillow plate 31 is used to support the front support 101 of the seat bottom support 100, and the front pressing member is used to press the front support 101; a rear locking member 4 is arranged at the rear of the lower frame 7, the rear locking member 4 includes a lining plate 41 and a rear pressing member, the lining plate 41 is used to support the rear support 102 of the seat bottom support 100, and a limiting stopper 43 is arranged on the edge of the lining plate 41, and the rear The clamping member is used to fix the rear support 102 on the lining plate 41; each leg frame 2 includes two vertical support legs and a horizontal connecting rod 17 fixedly connecting the two support legs, one of the support legs is provided with a plug 5, and the other support leg is provided with a socket 16, and the plug 5 is provided on the same side. When two identical transfer racks are placed symmetrically up and down, the plug 5 of the upper leg frame 2 can be inserted into the socket 16 of the lower leg frame 2, and similarly, the plug 5 on the lower leg frame 2 can be inserted into the socket 16 of the upper leg frame 2, as shown in FIG. Fig.11 shown.

[0027] In addition, when three or more layers of transfer racks need to be stacked, the base frames 1 need to be stacked back to back. In order to increase the stability between two adjacent layers of base frames 1, an angle positioning member 6 is set at each of the four corners of the base frame 1. The angle positioning member 6 includes a shaft sleeve 62 and an insertion shaft 61. When the entire transfer rack is placed upright, the lower end of the insertion shaft 61 extends out of the shaft sleeve 62. When two transfer racks are stacked back to back, the lower insertion shaft 61 is retracted into the shaft sleeve 62, and the upper insertion shaft 61 is inserted into the lower shaft sleeve 62, so that the two base frames 1 are fixed to each other, ensuring that the stacked transfer racks can remain stable. In order to limit the insertion shaft 61, a limit plate 63 is set above the shaft sleeve 62. After the insertion shaft 61 is retracted into the shaft sleeve 62, it touches the limit plate 63. In order to prevent the inserted insertion shaft 61 from detaching from the shaft sleeve 62, the insertion shaft 61 is set to an "L" shape. After the insertion shaft 61 is inserted into the shaft sleeve 62, the insertion shaft 61 is rotated and stuck on the lower edge of the upper frame 8, such as Fig.12 shown.

[0028] In this embodiment, the base frame 1 is used to place the seat support seat 100, and the front locking member 3 and the rear locking member 4 arranged thereon can respectively lock the front support 101 and the rear support 102 of the seat base support seat 100, thereby fixing the seat support seat 100 on the base frame 1, and the leg support frame 2 is arranged to form a rectangular storage space above the base frame 1 for protecting the seat, and the two transfer frames can be stacked up and down for use, and the backrests of the two fixed seats are placed in an offset and overlapping manner, so that a protective space is formed between the two transfer frames. The transfer frame is a metal frame with a stable structure. In addition to having good fixing performance, it can also be reused, which can reduce packaging costs while ensuring complete protection of the seat.

[0029] Specifically, the front clamping member at the front of the upper frame 8 includes a clamping rod 32 and a pre-tightening bolt 35, wherein the rear of the clamping rod 32 is movably pressed on a rear support 33 provided on the base frame 1. A waist-shaped hole 34 is provided on the clamping rod 32, which penetrates the clamping rod 32 longitudinally. The pre-tightening bolt 35 is installed on the base frame 1 after longitudinally passing through the waist-shaped hole 34, and the clamping rod 32 can be moved forward and backward under the restriction of the waist-shaped hole 34. Before the front support 101 is placed on the limiting pillow plate 31, the clamping rod 32 can be moved forward to avoid the front support 101. After the front support 101 is placed, the clamping rod 32 is pressed on the front support 101 by moving the clamping rod 32 backward, as shown in FIG. Fig. 9 shown.

[0030] The rear clamping member includes two groups, each of which includes a pressure rod 42 and a clamping bolt 44. The pressure rod 42 includes a rotating part and a contact-pressure part. The rotating part is installed on the base frame 1 through the shaft seat 46, and the contact-pressure part can be pressed on the lining plate 41 by flipping. The pressure rods 42 of the two groups of rear locking members 4 independently fix the rear support 102. In this way, when one pressure rod 42 is deformed, the other pressure rod 42 can still play a fixing role. The clamping bolt 44 is installed on the base frame 1, and a clamping head 45 for clamping the contact-pressure part is provided on the clamping bolt 44. In the process of placing the rear support 102 on the lining plate 41, the pressure rod 42 is flipped to avoid the rear support 102. After the rear support 102 is placed on the lining plate 41, the pressure rod 42 is flipped and pressed on the rear support 102. Fig.10 shown.

[0031] The front clamping member and the rear clamping member of the above structure are both installed on the base frame 1 in a movable connection manner and will not separate from the base frame body during use, thereby preventing parts from being lost and ensuring that the transfer frame will not malfunction during recycling.

[0032] In addition, the leg frame 2 is connected to the base frame 1 in a foldable manner, and its specific installation structure includes leg mounting sleeves 9 arranged at the four corners of the base frame 1, and a leg mounting cavity 91 for mounting the leg frame 2 is arranged in the middle of the leg mounting sleeve 9, and the leg mounting cavity 91 extends to the lower part of the base frame 1; limiting holes 93 are respectively arranged on the left and right walls of the leg mounting sleeve 9, and a limiting shaft 94 that is movably clamped in the limiting hole 93 is arranged at the lower end of the leg frame 2, and an avoidance opening 92 pointing to the rear is arranged on the front leg mounting sleeve 9, and an avoidance opening 92 pointing to the front is arranged on the rear leg mounting sleeve 9, so that the leg frame 2 can lie flat on the base frame 1 after being moved upward and flipped over, thereby reducing the occupied space of the transfer rack and facilitating the transportation and storage of the transfer rack. In addition, the entire transfer rack includes two parts, the leg rack 2 and the bottom frame. The bottom frame has a complex structure, and the leg rack 2 needs to withstand huge pressure. When the leg rack 2 is damaged, the entire transfer rack can be restored to its original function by replacing a new leg rack 2, which can reduce the scrap rate of the product. In addition, each leg rack 2 is equipped with two springs 14, one end of the spring 14 is connected to the leg rack 2, and the other end is connected to the bottom frame 1. After the leg rack 2 is folded, the spring 14 tightly pulls the leg rack 2, so that the folded transfer rack maintains the stability of each component.

[0033] In order to meet various stacking requirements, the transfer rack is equipped with a top frame 18, and its specific structure is as follows: Figure 7 The top frame 18 includes four plug-in legs 19 corresponding to the supporting legs one by one, and the plug-in legs 19 are respectively provided with plugs 5 and sockets 16, so that the plug-in legs 19 can be plugged into the leg frame 2. When the transport rack loaded with seats is stacked in a single layer or an odd number of layers, the top frame 18 cooperates with the uppermost transport rack, so that a single transport rack can also form a complete protection space.
