[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0025] Example 1

[0026] Reference Figure 1 , Figure 2 and Figure 5 This is the first embodiment of the present utility model. This embodiment provides a locomotive electronic and electrical test bench for use in rail transit. The locomotive electronic and electrical test bench for use in rail transit includes a main body component and an installation component. The two work together to make full use of the operator's training time. The distance of the training screen can be adjusted according to the user's arm span.

[0027] Specifically, the main component 100 includes a training table 101, casters 102, and a storage drawer 103. The casters 102 are rotatably connected to the bottom of the training table 101, and the storage drawer 103 is movably connected to the inside of the training table 101.

[0028] The training table 101 adopts a double-layer matte textured powder coating structure made of iron. The tabletop is made of fireproof, waterproof and wear-resistant high-density board. There are four casters 102, which makes the equipment more flexible and convenient to move. There are seven storage drawers 103.

[0029] Specifically, the installation component 200 is set on the top of the training table 101 and includes a movable component 201, a training screen module mounting component 202, and a limiting component 203. The movable component 201 is located on the top of the training table 101, the training screen module mounting component 202 is set on one side of the movable component 201, and the limiting component 203 is located on one side of the movable component 201.

[0030] By setting up the training screen module mount 202, it is easier and more convenient for operators to replace the corresponding training modules. The movable part 201 allows the training screen to be adjusted to a relatively comfortable operating distance according to the operator's arm span.

[0031] Example 2

[0032] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the movable component 201 includes a guide rail 201a and a movable support frame 201b. The guide rail 201a is fixed to the top of the training table 101, and the movable support frame 201b is movable outside the guide rail 201a.

[0034] There are two guide rails 201a, both of which are set on the top of the training table 101. The movable support frame 201b can move horizontally along the outside of the guide rail 201a.

[0035] Specifically, the movable component 201 also includes an aluminum alloy profile 201c and a push-pull block 201d. The aluminum alloy profile 201c is fixed to the inside of the movable support frame 201b, and the push-pull block 201d is fixed to one side of the movable support frame 201b.

[0036] There are two aluminum alloy profiles 201c, which are installed inside the movable support frame 201b. They are lightweight and high-strength. The push-pull block 201d has threaded holes on its inner side.

[0037] Specifically, the movable component 201 also includes a bracket 201e, a threaded rod 201f, a quick crank 201g, and a gear 201h. The bracket 201e is fixed to the top of the training table 101, the threaded rod 201f is rotatably connected to one side of the bracket 201e, the quick crank 201g is fixed to the end of the threaded rod 201f, and the gear 201h is fixed to the outside of the threaded rod 201f.

[0038] By rotating the quick crank handle 201g, the quick crank handle 201g drives the threaded rod 201f. The rotation of the threaded rod 201f causes the push-pull block 201d, which moves on its outer side, to move the movable support frame 201b, thereby realizing the distance adjustment function.

[0039] Specifically, the training screen module mount 202 includes a slide 202a and a mesh mounting plate 202b. The slide 202a is fixed to one side of the aluminum alloy profile 201c, and the mesh mounting plate 202b is movable inside the slide 202a.

[0040] There are two slides 202a and two mesh hanging plates 202b. The mesh hanging plate 202b is used for the installation of electrical components in practical training, independent innovation of practical training content, and expansion and upgrading of practical training content.

[0041] Specifically, the training screen module mount 202 also includes an electrical engineering general skills training module 202c, which is fixed to one side of the mesh mounting plate 202b.

[0042] The Skills Training Module 202c comes in various types, and operators can install or replace the corresponding Skills Training Module 202c according to different requirements.

[0043] Example 3

[0044] Reference Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the limiting component 203 includes a housing 203a, a limiting rod 203b, a handle 203c, a baffle 203d, and a spring 203e. The housing 203a is fixed to one side of the bracket 201e. One end of the limiting rod 203b passes through the housing 203a and is fixed to the end of the handle 203c. The other end of the limiting rod 203b meshes with the gear 201h. The baffle 203d is fixed to the outside of the limiting rod 203b. The end of the spring 203e is fixed to one side of the baffle 203d.

[0046] By pulling the handle 203c, the handle 203c moves the end of the limit rod 203b to a position where it is no longer engaged with the gear 201h, thus realizing the function of releasing the limit. When the handle 203c is released, the spring 203e pushes the baffle 203d, and the baffle 203d moves the end of the limit rod 203b to a position where it is engaged with the gear 201h, thus realizing the function of locking the limit.

[0047] When using the device, the operator first installs or replaces the general electrical skills training module 202c according to different needs. Then, the operator pulls the handle 203c. The handle 203c moves the end of the limit rod 203b to a position where it no longer meshes with the gear 201h. Then, the operator rotates the quick crank 201g. The quick crank 201g drives the threaded rod 201f. The rotation of the threaded rod 201f causes the push-pull block 201d, which moves on its outer side, to move the movable support frame 201b. Once the position is adjusted to a comfortable position for the operator, the operator can release the handle 203c.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
