Description

Technical Field

[0001] This utility model relates to the field of seat tray production, and in particular to a seat tray placement rack. Background Technology

[0002] The tray is located at the bottom of the seat, connecting the seat cushion, backrest, armrests and other components to the ground. It bears the overall weight of the seat, the load on the human body and the adjustment function. At the same time, it must meet multiple requirements such as stability, comfort, durability and safety. Its design directly affects the ergonomic performance of the seat and is the basis for realizing the seat height adjustment, rotation and tilt functions.

[0003] Currently, when producing seat trays, it is necessary to store the finished seat trays. In the process of storing seat trays, traditional storage racks often have problems such as large footprint, inconvenience in placing seat trays, and poor stability. In addition, multiple seat trays are easily stacked together, making it difficult to pick up individual seat trays. In order to better place seat trays independently and reduce the footprint of seat trays, it is necessary to invent a seat tray storage rack to meet the above needs. Utility Model Content

[0004] The purpose of this utility model is to provide a seat tray holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seat tray holder, comprising a lower rectangular fixing frame and an upper rectangular fixing frame, wherein fixing rods are connected to the top four corners of the lower rectangular fixing frame, and support rods are connected to the bottom four corners of the upper rectangular fixing frame, wherein the bottom of the support rods has slots corresponding to the fixing rods, and multiple sets of limiting rods are connected to the top of the two longitudinal portions of the lower and upper rectangular fixing frames, each set consisting of two limiting rods, which are equidistantly distributed in each set, and triangular support plates are connected to the center of the two horizontal portions of the lower and upper rectangular fixing frames.

[0006] Preferably, the outer walls of the support rod and the fixing rod are provided with corresponding pin holes, and the pin holes are provided with insert pins.

[0007] The above settings can be used to lock the support rod and the fixing rod.

[0008] Preferably, each of the four bottom corners of the lower rectangular fixing frame is connected to a support leg, and the other end of the support leg is equipped with a caster wheel, and the caster wheel is provided with a brake pad.

[0009] The above settings allow for the movement of the shelf, improving its flexibility.

[0010] Preferably, two fixing plates are connected to opposite sides of the two horizontal portions of the lower rectangular fixing frame and the upper rectangular fixing frame, and a rectangular support plate is connected between the two opposite fixing plates.

[0011] The above settings can be used to provide auxiliary support for the seat tray.

[0012] The technical effects and advantages of this utility model are as follows: By setting multiple sets of limiting rods, each set of limiting rods can hold a seat tray, and the triangular support plate in the middle can support the middle of the seat tray. The double-layer setting not only allows for the placement of multiple seat trays, but also effectively saves the floor space occupied by the seat trays. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figure 1-4 The illustrated seat tray holder includes a lower rectangular fixing frame 1 and an upper rectangular fixing frame 2. The seat tray is placed on the upper rectangular fixing frame 2, as shown. Figure 4As shown, fixing rods 3 are fixedly connected to the top four corners of the lower rectangular fixing frame 1, and support rods 4 are fixedly connected to the bottom four corners of the upper rectangular fixing frame 2. The bottom of each support rod 4 has a slot corresponding to the fixing rod 3. The lower rectangular fixing frame 1 and the upper rectangular fixing frame 2 are a split design. The seat tray can be placed on the lower rectangular fixing frame 1 first, and then the upper rectangular fixing frame 2 can be placed on the lower rectangular fixing frame 1. At this point, the seat tray can be placed on the upper rectangular fixing frame 2. This split design does not make it difficult to place the seat tray on the lower rectangular fixing frame 1, and the double-layer design effectively reduces the difficulty of placement. The frame occupies a certain area. Multiple sets of limiting rods 5 are fixedly connected to the top of the two longitudinal sections of the lower rectangular fixing frame 1 and the upper rectangular fixing frame 2. Each set of limiting rods 5 consists of two rods, which are equidistantly distributed. The limiting rods 5 are designed according to the shape of the seat tray. This design allows the seat tray to be secured to the limiting rods 5, limiting its position. Triangular support plates 6 are fixedly connected to the center of the two horizontal sections of the lower rectangular fixing frame 1 and the upper rectangular fixing frame 2. These triangular support plates 6 directly support the center of the seat tray, thereby improving the stability of the seat tray.

[0017] The outer walls of the support rod 4 and the fixing rod 3 are provided with corresponding pin holes, and the pin holes are provided with pins 7. By inserting the pins 7 into the pin holes on the support rod 4 and the fixing rod 3, the support rod 4 and the fixing rod 3 can be locked, thereby improving the stability of the upper seat tray.

[0018] Support legs 8 are fixedly connected to the four corners of the bottom of the lower rectangular fixed frame 1. The other end of the support leg 8 is equipped with a caster wheel 9, and the caster wheel 9 is equipped with a brake pad. By setting the support leg 8 at the bottom of the lower rectangular fixed frame 1, the lower rectangular fixed frame 1 can be supported. Furthermore, the caster wheel 9 at the bottom of the support leg 8 can also move the entire placement rack.

[0019] Two fixing plates 10 are fixedly connected to opposite sides of the two horizontal portions of the lower rectangular fixing frame 1 and the upper rectangular fixing frame 2. A rectangular support plate 11 is fixedly connected between the two opposite fixing plates 10. The rectangular support plate 11 is connected to the fixing plate 10 and is located at the bottom of the lower rectangular fixing frame 1 and the upper rectangular fixing frame 2. Therefore, the height of the rectangular support plate 11 is lower than that of the triangular support plate 6, which can provide auxiliary support for the seat tray with an arc shape at the bottom.

[0020] The working principle of this utility model is as follows: By clamping the seat trays onto the limiting rods 5 on the lower rectangular fixing frame 1 and placing them sequentially along the longitudinal part of the lower rectangular fixing frame 1, multiple seat trays are placed independently. The seat trays are supported by the triangular support plate 6 and the rectangular support plate 11. After the lower rectangular fixing frame 1 is full, the upper rectangular fixing frame 2 is placed on the lower rectangular fixing frame 1. The support rod 4 at the bottom of the upper rectangular fixing frame 2 is sleeved on the outside of the fixing rod 3 on the lower rectangular fixing frame 1 and locked by inserting the pin 7. At this time, seat trays can continue to be placed on the upper rectangular fixing frame 2.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
