Description

Technical Field

[0001] The utility model relates to the field of library lending vehicles, and specifically discloses a library lending vehicle. Background Art

[0002] In the process of using the existing library lending cart, a ladder is required to be used separately for taking books placed at a higher position, and the books need to be taken up and put down one by one, which is very inconvenient. In addition, when changing the position for taking books, the library lending cart and the ladder need to be moved separately, which is troublesome to use. Utility Model Content

[0003] In view of the above-mentioned defects or shortcomings in the prior art, the present application aims to provide a library lending vehicle, comprising a base plate, a first fixed plate and a second fixed plate fixedly mounted on the top of the base plate, a third fixed plate fixedly mounted between the first fixed plate and the second fixed plate, a fixed shaft rotatably connected to the inside of one side of the bottom of the base plate, wheels fixedly sleeved on the outside of both ends of the fixed shaft, and a universal wheel fixedly mounted on the other side of the bottom of the base plate, the second fixed plate being arranged at an incline, and a transverse plate distributed at equal intervals and located between the base plate and the third fixed plate being fixedly mounted between the second fixed plate and the first fixed plate, a ladder assembly being fixedly mounted on the side of the second fixed plate away from the transverse plate, and a reset mechanism fixedly mounted on the second fixed plate is arranged on the inner side of the ladder assembly.

[0004] Preferably, the ladder assembly comprises a slide seat fixedly mounted on the second fixed plate, and the outer side of the slide seat is slidably connected to the ladder via a slide rail.

[0005] Preferably, a support plate is provided at the bottom of the ladder, and a friction pad which is symmetrically distributed and has a cylindrical boss at the bottom is fixedly mounted at the bottom of the support plate.

[0006] Preferably, the reset mechanism comprises a fixed block fixedly mounted on the second fixed plate and a fixed rod arranged on the outside of the ladder and one end of which is movably sleeved inside the fixed block, and a spring is sleeved inside the fixed block.

[0007] Beneficial effects:

[0008] 1. The library lending cart uses a sliding seat and a sliding rail in coordination, so that when a person stands on it, he can press the ladder to slide by his own weight, and then the friction pad at the bottom of the support plate supports the ladder and the friction between the friction pad and the ground limits the lending cart to prevent it from moving. At this time, the person can climb the ladder to get the books at a high place, and when the lending cart is not in use, the elastic force of the spring can be used to drive the ladder to reset and release the limit on the lending cart, so that the ladder can be connected to the lending cart and move synchronously, which is very convenient.

[0009] 2. The library lending cart installs horizontal boards with equal spacing between the slide rail and the second fixed plate, so that when people stand on the ladder to take books, they can directly place the books on the higher horizontal board. People do not need to go up and down the ladder to take and put books. Books in low positions can be directly placed on the lower bottom plate or horizontal board, which is more convenient to use.

DETAILED DESCRIPTION

[0016] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0017] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0018] See also Figure 1-4A library lending vehicle comprises a base plate 1, a first fixed plate 2 and a second fixed plate 3 fixedly mounted on the top of the base plate 1, a third fixed plate 4 fixedly mounted between the first fixed plate 2 and the second fixed plate 3, a fixed shaft 5 rotatably connected to the inside of one side of the bottom of the base plate 1, wheels 6 fixedly sleeved on the outside of both ends of the fixed shaft 5, and a universal wheel 7 fixedly mounted on the other side of the bottom of the base plate 1, through which the lending vehicle can be steered, the second fixed plate 3 is inclined, and a transverse plate 8 distributed at equal intervals and located between the base plate 1 and the third fixed plate 4 is fixedly mounted between the second fixed plate 3 and the first fixed plate 2, books can be placed through the transverse plate 8, and books can also be placed on the top of the base plate 1, a ladder assembly 9 is fixedly mounted on the side of the second fixed plate 3 away from the transverse plate 8, and a reset mechanism 10 fixedly mounted on the second fixed plate 3 is arranged on the inner side of the ladder assembly 9.

[0019] Among them, the ladder assembly 9 includes a slide 91 fixedly installed on the second fixed plate 3, and the outer side of the slide 91 is slidably connected to the ladder 93 through a slide rail 92. Through the coordinated use of the slide 91 and the slide rail 92, when a person climbs the ladder 93, the ladder 93 can be driven to move under the action of the person's own gravity. At the same time, when the person walks down the ladder 93, it can be reset under the elastic force of the spring 103.

[0020] Among them, a support plate 11 is provided at the bottom of the ladder 93, and a friction pad 12 which is symmetrically distributed and has a cylindrical boss at the bottom is fixedly installed at the bottom of the support plate 11. The friction between the friction pad 12 and the ground can limit the position of the borrowing vehicle, so that the borrowing vehicle will not move when people climb the ladder 93.

[0021] Among them, the reset mechanism 10 includes a fixed block 101 fixedly installed on the second fixed plate 3 and a fixed rod 102 arranged on the outside of the ladder 93 and one end of which is movably sleeved inside the fixed block 101. The fixed rod 102 allows people to climb the ladder 93 by compressing the spring 103 through the fixed rod 102 and storing energy for the reset driving force of the ladder 93. The fixed block 101 is internally sleeved with a spring 103. The fixed block 101 can limit the ladder 93 and can also drive the ladder 93 to reset through the elastic force of the spring 103, so as to move the lending vehicle.

[0022] When the borrowing cart is in use, the borrowing cart is pushed and moved to the side of the bookshelf. Books at a lower position can be directly placed on the lower bottom plate 1 or the horizontal plate 8 for storage. For books at a higher position, a person climbs on the ladder 93. At this time, the ladder 93 is pressed to move by the person's own gravity, and the friction pad 12 at the bottom of the support plate 11 is used to limit the ladder 93, and the taken books are placed on the higher horizontal plate 8 for storage. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
