Description

Technical Field

[0001] The utility model relates to the technical field of voltage meter storage, in particular to a voltage transformer storage and placement box. Background Art

[0002] A voltmeter is an instrument for measuring voltage. The structure of a voltmeter is as follows: a permanent magnet is inside a sensitive ammeter, a coil composed of a wire is connected in series between two terminals of the ammeter, the coil is placed in the magnetic field of the permanent magnet, and is connected to the pointer of the meter through a transmission device. Teaching voltmeters, etc., need to be easy to carry. Existing voltmeter storage devices appear messy when storing multiple voltmeters, and the wires are intertwined, affecting use. A single container for storing voltmeters increases the temporary volume and is easy to miss. Utility Model Content

[0003] The purpose of the utility model is to provide a voltage conversion storage and retrieval box to overcome the above-mentioned defects in the prior art.

[0004] The cam is an angular channel that is formed on a pair of cam faces the side of the cam, and a channel is formed between the cam and the frame, and the channel is connected to the cam by a threaded spring.

[0005] The beneficial effects of the utility model are:

[0006] The anti-skid elastic pad is supported tightly against the rear end face of the support frame to prevent the support frame from rotating backwards, and the anti-skid elastic pad and the support spring are used for buffering, so that the voltmeter is in close contact with the through cavity and the support frame to prevent the storage box from being affected by vibration and causing the voltmeter to fall. At the same time, during the backward movement of the threaded bracket, the support spring provides supporting force to the support frame to prevent the voltmeter from falling by itself when it is pushed, thereby enhancing the safety of the voltmeter and achieving the effect of storing and taking the voltmeter for personal use.

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0017] Reference Figure 1-Figure 6According to an embodiment of the utility model, a voltage conversion storage and retrieval box includes a storage box 10, which is provided with a through cavity 11 opened on the left and right sides. A threaded rod 18 is rotatably connected to the rear side wall of the through cavity 11, and a threaded bracket 19 is threadedly connected to the outer periphery of the threaded rod 18. The threaded bracket 19 is arranged in a concave shape, and the two front end protruding ends of the concave shape of the threaded bracket 19 extend forward into the through cavity 11. A fixed frame 13 is fixed in the through cavity 11, and a sliding plate 14 is slidably connected to the fixed frame 13. A connecting device is provided between the fixed frame 13 and the sliding plate 14. There is a tension spring 15, the front end of the sliding plate 14 is abutted with a support frame 17, a hinge rod 16 is connected between the sliding plate 14 and the support frame 17, a voltmeter 12 is provided on the support frame 17, the support frame 17 is L-shaped and abuts against the lower end surface of the voltmeter 12, the two front end parts of the threaded insert 19 are sleeved with anti-skid elastic pads 20, the anti-skid elastic pads 20 abut against the rear end surface of the support frame 17, the two front end parts of the threaded insert 19 are fixed with support plates 21 at the ends close to each other, and a support spring 22 is connected between the support frame 17 and the support plate 21;

[0018] The user can directly insert the voltmeter 12 from the left or right end into the through cavity 11 that passes through the left and right sides for placement and storage, and then rotate the threaded rod 18 to move the threaded bracket 19 forward, so that the anti-skid elastic pad 20 is closely supported by the rear end surface of the support frame 17, so that the side wall of the through cavity 11 and the support frame 17 clamp the voltmeter 12 front and back to prevent it from falling. When the user takes the voltmeter 12 located at the middle end, the user can rotate the threaded rod 18 in the opposite direction, so that the threaded rod 18 drives the threaded bracket 19 to move backward, and the anti-skid elastic pad 20 is separated from the support frame 17. Then, the support spring 22 connected between the support frame 17 and the support plate 21 is relaxed, and the front end of the support spring 22 is always in contact with the support frame 17, and the supporting force of the support spring 22 on the support frame 17 is reduced. Under the connection between the sliding plate 14 and the support frame 17 through the hinge rod 16, the user pushes the front end of the voltmeter 12, the tension spring 15 supports the sliding plate 14, and the support spring 22 supports the support frame 17, so that the support frame 17 can slide backward with the hinge rod 16 as the rotation axis, overcome the spring force of the support spring 22, and thereby make the front end face of the voltmeter 12 disengage from the contact with the through cavity 11.

[0019] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
