Description

Technical Field

[0001] The utility model relates to the technical field of carriages, in particular to a foldable flower-rail carriage. Background Art

[0002] The folding carriage is a specially designed carriage for transporting various types of cargo, especially when it is necessary to increase the loading height or change the distribution of cargo. This type of carriage has a flexible design and is easy to operate, making it very suitable for transporting different cargoes when the interior space of the carriage needs to be adjusted.

[0003] However, in the process of adjusting the height of traditional flower-rail carriages currently on the market, most of them use latches and multiple railings to stack layer by layer to make the height of the carriage reach the required height. The process requires two or more people to cooperate to complete the operation, because the length of the railings used in the carriages is mostly two meters and they are heavy. Therefore, during the installation process, one person is required to support another person to plug in the latches to complete the assembly.

[0004] On the one hand, the process is relatively labor-intensive. On the other hand, when installing to a higher level, it is necessary to use a ladder or workers to climb onto the installed guardrails to carry out construction work, which makes the operation process dangerous. For example, when working at high altitude, a safety rope needs to be tied when the height reaches two meters. However, workers with weak safety awareness will not tie the safety rope. Therefore, traditional car height adjustment is very dangerous.

[0005] Therefore, we specially propose a foldable flower fence carriage. Summary of the Invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 4 to 6 , the utility model provides a technical solution:

[0034] A foldable flower-rail carriage comprises a carriage bottom 1, wherein lower channel steels 2 are fixedly installed transversely at the front and rear edges of the upper end of the carriage bottom 1, and upper channel steels 3 are rotatably installed on the upper ends of multiple lower channel steels 2. A height component 6 is provided between the lower channel steels 2 and the upper channel steels 3 with opposite transverse openings. The height component 6 comprises a lower cross bar 62 slidably installed between two lower channel steels 2 with opposite transverse openings, an upper cross bar 61 is provided above the lower cross bar 62, and a first adjusting rod 66 is rotatably installed between the upper cross bar 61 and the lower cross bar 62 and between the lower cross bar 62 and the carriage bottom 1.

[0035] The lower end of the first adjusting rod 66 is rotatably installed inside the adjacent lower channel steel 2, wherein the front end surface of the lower channel steel 2 on which the first adjusting rod 66 is rotatably installed is rotatably installed with a ratchet 65 and a pawl 22, and the pawl 22 is located above the ratchet 65 and engages with the ratchet 65. The front end surface of the ratchet 65 is fixedly installed with an adjusting disk 64, and the rear end surface of the ratchet 65 is fixedly connected to the cylinder on which the first adjusting rod 66 rotates; the interiors of the three lower channel steels 2 on the left side without the ratchet 65 are rotatably installed with an oblique support rod 67, and the upper end of the oblique support rod 67 is rotatably installed with an upper oblique rod 69 and a connecting rod 691, and the upper oblique rod 69 and the connecting rod 691 are located one in front and one behind, and the lower end of the connecting rod 691 is rotatably installed on the first adjusting rod 66, and the upper end of the first adjusting rod 66 is rotatably installed with a U-shaped section rod 68 and a support rod 70, and the U-shaped section rod 68 and the support rod 70 are located one in front and one behind.

[0036] A limiting transverse groove 63 is provided from the front end face to the rear end face of the lower transverse bar 62, and a slide 631 is slidably installed inside the limiting transverse groove 63. The upper end of the U-shaped section rod 68 is rotatably installed on the inner circumferential surface of the slide 631, the upper end of the support rod 70 is rotatably installed on one end of the inner side of the lower transverse bar 62, and the upper end of the upper oblique rod 69 is rotatably installed on the other end of the inner side of the lower transverse bar 62; an oblique support rod 67, a U-shaped section rod 68, an upper oblique rod 69, a connecting rod 691, and a support rod 70 are also provided between the upper transverse bar 61 and the lower transverse bar 62, and the upper transverse bar 61 and the lower transverse bar 62, as well as the lower transverse bar 62 and the car bottom 1 are in a mirror image state.

[0037] By adopting the above technical solution, when in use, the operator uses a hollow steel pipe to nest on one of the cylinders on the circumferential surface of the adjusting disk 64, and then uses the lever principle to rotate the adjusting disk 64. When the adjusting disk 64 rotates, it will rotate synchronously with the ratchet 65, and under the action of the pawl 22, the ratchet 65 can be kept in a fixed state. It should be noted that the operator can manually move the pawl 22 to release the restriction on the ratchet 65.

[0038] When the adjusting disk 64 rotates, it will cause the first adjusting rod 66 to rotate synchronously, and when the first adjusting rod 66 rotates, it will cause the connecting rod 691 to move synchronously, and the connecting rod 691 will cause the diagonal support rod 67 to rotate synchronously, and then the upper end of the diagonal support rod 67 will drive the upper diagonal rod 69 to rotate synchronously. At this time, the first adjusting rod 66 drives the support rod 70 to rotate synchronously, and the first adjusting rod 66 will simultaneously drive the U-shaped section rod 68 to rotate synchronously, and the U-shaped section rod 68 will drive the slide 631 to slide horizontally inside the limiting horizontal groove 63.

[0039] At this time, the lower cross bar 62 can slide horizontally between the two lower channel steels 2 with the two openings facing each other under the action of the structures such as the upper inclined rod 69 and the support rod 70, and in addition, it needs to be explained that in the process of upward sliding of the lower cross bar 62, since the structure between the upper cross bar 61 and the lower cross bar 62 is the same, but in a mirror image state, therefore in the process of upward movement of the lower cross bar 62, the upper cross bar 61 also slides upward synchronously, at this time, the mounting sliding groove 621 moves synchronously with the upward movement of the lower cross bar 62 and the upper cross bar 61, so as to change the length of the combination of the mounting sliding groove 621 and the fixed plate 7, and then when the height is lowered, only the ratchet 65 needs to be rotated in the opposite direction.

[0040] Specifically, as shown in Figures 1 to 6 The upper end surface of the carriage bottom 1 is horizontally fixedly installed with a plurality of fixed plates 7 at the positions of the outer side of the height assembly 6 and the front and rear edges of the upper end surface of the lower cross bar 62, the lower end surface of the lower cross bar 62 and the lower end surface of the upper cross bar 61 are fixedly installed with mounting sliding grooves 621 matched with the fixed plates 7 at the positions of the front and rear edges, and the upper end of the fixed plate 7 is slidingly installed in the inside of the mounting sliding groove 621.

[0041] The corners of the front and rear end surfaces of the lower channel steel 2 with the openings facing away from each other are fixedly installed with arc-shaped limiting grooves 21, the corners of the front and rear end surfaces of the upper channel steel 3 with the openings facing away from each other are slidingly installed in the inside of the arc-shaped limiting grooves 21 by using a cylinder, two support channel rods 41 are arranged between the two lower channel steels 2 and the upper channel steel 3 on the rightmost side in the longitudinal direction, the lower ends of the two support channel rods 41 are rotationally connected to the inner side surfaces of the adjacent lower channel steels 2, and an upper gantry 42, a middle gantry 43 and a lower gantry 44 are arranged between the two support channel rods 41.

[0042] By adopting the above technical scheme, when in use, the two support channel rods 41 on the upper end surface of the carriage bottom 1 are directly rotated, and it needs to be explained that the support channel rod 41 will not rotate under the condition that it is not manually pulled by a person, so as to ensure the safety of the subsequent structure.

[0043] Then the operator can directly pull out the upper gantry 42, the middle gantry 43, and the lower gantry 44, and fold them together, so that the operator can easily take the entire gantry and prevent injuries to personnel due to unstable center.

[0044] Secondly, with the cooperation of the above-mentioned multiple structures, the railings of the carriage can be reinforced. For example, traditional railings on the market are supported by thin patches or hollow columns, and their protective effect is poor.

[0045] Therefore, as shown in the above structure, during use, the mounting groove 621 and the fixing plate 7 are in the original protective structure, and at this time, the other structures of the height component 6 are located inside the mounting groove 621 and the fixing plate 7, thereby forming a new layer of protection, thereby forming good protection against external impacts. When the outermost layer of protection of the car is damaged when it is hit, there is still protection inside to ensure the safety of objects inside the car.

[0046] Working principle: First, the operator rotates the support slot rod 41, the upper gantry 42, the middle gantry 43, and the lower gantry 44 are combined together to form a protection for the front of the vehicle.

[0047] Secondly, the lever principle is used to rotate the adjusting disk 64, so that the ratchet 65 and the first adjusting rod 66 can rotate synchronously, so that the height component 6 can drive the lower cross bar 62 to move upward or downward, and the upper cross bar 61 can do the same movement, thereby changing the overall height of the car.

[0048] Then the operator rotates the upper channel steel 3 to cover the outer side of the upper cross bar 61 to form an overall adjustment of the car body and protect the upper cross bar 61.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
