Description

Technical Field

[0001] The utility model belongs to the technical field of lifting frames, and in particular relates to a novel scissors frame. Background Art

[0002] A scissor rack is an extension device that is arranged in an X-shaped structure and is used to increase the height or length.

[0003] In order to achieve a certain telescopic length, the existing scissor racks require a large number of scissor rack layers, which will occupy a large space, thereby increasing the space occupied by the entire body. Whether in use or folded, it will occupy too much space, which is inconvenient to install and store. Under such technical background, a new type of scissor rack is proposed, which can reduce the space occupied in the folded state while keeping the telescopic length unchanged, so that the overall space occupied by the scissor rack is reduced.

[0006] As an improvement, the two scissor racks are located on both sides of the base plate, the one facing downward is scissor rack one, and the one facing upward is scissor rack two, and the scissor rack one facing downward is slidably connected to a group of guide grooves above, and the scissor rack two facing upward is slidably connected to a group of guide grooves below.

[0007] As an improvement, the scissor frame is composed of a plurality of connecting rods arranged in an interlaced manner, and the length of the plurality of connecting rods is the same as the length of the base plate, and the length of the adjusting rod is 1 / 2 of the length of the plurality of connecting rods.

[0008] As an improvement, the connection between the adjustment rod and the base plate on one side is located in the middle position of a group of guide grooves connected to the scissors frame on that side, and the two adjustment rods located on both sides of the base plate are parallel to each other and connected in the opposite direction to the scissors frame.

[0009] The advantages of the utility model compared with the prior art are:

[0010] The scissors frame is provided with scissors frames in different directions on both sides of the fixing plate, so that the scissors frames can be extended from both sides at the same time, so that the length of the scissors frame in a single direction is doubled without increasing the volume occupied by the scissors frame.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0017] Embodiment 1:

[0018] As the instruction manual Figure 1-3As shown, a novel scissor frame 2 includes a base plate 1 and two scissor frames 2, the scissor frames 2 are composed of a plurality of connecting rods 8 arranged in an interlaced manner, and the length of the plurality of connecting rods 8 is the same as the length of the base plate 1, and the four corners of the base plate 1 are respectively provided with guide grooves 3 which penetrate the base plate 1 transversely, wherein the two transverse guide grooves 3 form a group, the two scissor frames 2 are respectively located on both sides of the base plate 1, and the two scissor frames 2 are respectively facing the upper and lower ends of the base plate 1, the two scissor frames 2 are located on both sides of the base plate 1, the downward one is scissor frame 21, and the upward one is scissor frame 22, and the downward one is slidably connected to the upper group of guide grooves 3, and the upward one is slidably connected to the lower group of guide grooves 3.

[0019] In the utility model, one end of the two scissor frames 2 are slidably connected to a group of guide grooves 3 through a pulley 4, and adjusting rods 5 are rotatably connected to both sides of the middle of the base plate 1. The length of the adjusting rod 5 is 1 / 2 of the length of the plurality of connecting rods 8. The other end of the adjusting rod 5 is rotatably connected to the middle of the bottom of the two scissor frames 2. The connection between the adjusting rod 5 on one side and the base plate 1 is located in the middle position of a group of guide grooves 3 connected to the scissor frame 2 on this side, and the two adjusting rods 5 located on both sides of the base plate 1 are parallel to each other and are connected in opposite directions to the scissor frames 2.
