Description

Technical Field

[0001] The utility model relates to the field of pressure instrument calibration, in particular to a portable pressure gauge calibrator. Background Art

[0002] Pressure instruments are instruments installed on site. Due to their large number and prone to failure, their repair and maintenance are very large. Currently, the first method of repairing pressure instruments is on-site repair, which means bringing calibration instruments such as indicators, voltage-stabilized power supplies, standard pressure gauges, and pressure calibrators to the site. This operation is cumbersome, inefficient, and not easy to carry. In addition, they are easily bumped and vibrated during transportation, causing damage to the instrument or errors, which does not meet the needs of fast and efficient production. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a portable pressure gauge calibrator, aiming to improve the problems of inconvenience in carrying and lack of protection of the device in the prior art.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a portable pressure gauge calibrator, comprising a shell, a door panel is provided on the front of the shell, a calibrator body is provided inside the door panel, anti-collision mechanisms are provided on both sides of the shell, and a carrying mechanism is provided on the top of the shell;

[0005] The anti-collision mechanism includes a protective plate, a connecting column is provided on one side of the protective plate, a first spring is provided in the connecting column, movable rods are hinged on both sides of the connecting column, a moving block is hinged on the other side of the movable rod, a second spring is provided on one side of the moving block, and a limit block is provided on one side of the second spring.

[0006] As a further description of the above technical solution:

[0007] The carrying mechanism comprises a fixing plate, a hand strap is arranged between the fixing plates, and a locking piece is arranged at the front end of one of the fixing plates.

[0008] As a further description of the above technical solution:

[0009] A support plate is provided inside the shell, and the support plate is connected to one side of the connecting column.

[0010] As a further description of the above technical solution: openings are provided on both sides of the shell.

[0011] As a further description of the above technical solution:

[0012] The outer sides of the protective plates are all provided with sponge bodies.

[0013] As a further description of the above technical solution:

[0014] Damping mechanisms are provided in both the first spring and the second spring.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with a sponge body, a protective plate, a connecting column, a first spring, a movable rod, a moving block, a second spring and a limit block. During the transportation process, when a collision accidentally occurs, after the protective plate receives the impact force, the connecting column contracts under the action of the first spring, and at the same time the movable rod presses the moving block to both sides, so that the moving block presses the second spring. Therefore, the second spring and the first spring can offset the impact force, and the sponge body can protect the impact object; avoid errors in the calibration instrument body after receiving the impact force, and improve the safety of the device.

[0017] 2. The utility model is provided with a fixing plate, a hand strap and a locking piece, and the length of the hand strap is adjusted by twisting the locking piece, thereby improving the flexibility and portability of the device, making it easier to carry and improving practicality.

[0024] 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.

[0025] Reference Figure 1-4 The utility model provides an embodiment: a portable pressure gauge calibrator, comprising a housing 1, a door panel 2 is provided on the front of the housing 1, a calibrator body 3 is provided inside the door panel 2, anti-collision mechanisms 4 are provided on both sides of the housing 1, and a carrying mechanism 5 is provided on the top of the housing 1;

[0026] The anti-collision mechanism 4 includes a protective plate 401, a connecting column 402 is provided on one side of the protective plate 401, a first spring 403 is provided in the connecting column 402, movable rods 404 are hinged on both sides of the connecting column 402, a moving block 405 is hinged on the other side of the movable rod 404, a second spring 406 is provided on one side of the moving block 405, and a limit block 407 is provided on one side of the second spring 406.

[0027] Reference Figure 1-4 The carrying mechanism 5 includes a fixing plate 501 , a hand strap 502 is provided between the fixing plates 501 , and a locking member 503 is provided at the front end of one of the fixing plates 501 .

[0028] By twisting the locking member 503, the hand strap 502 is put into an active state, so that the length of the hand strap 502 can be adjusted. After adjusting the applicable length, the locking member 503 is twisted in the reverse direction to lock the hand strap 502.

[0029] Reference Figure 1-4 , openings 7 are provided on both sides of the housing 1.

[0030] The housing 1 is provided with openings 7 on both sides to facilitate the movement of the anti-collision mechanism 4.

[0031] Reference Figure 1-4 , a sponge body 8 is provided on the outer side of the protective plate 401.

[0032] The outer side of the protective plate 401 is provided with a sponge body 8, and when a collision occurs, the sponge body 8 can protect the impact object.

[0033] Reference Figure 1-4 , damping mechanisms are provided in both the first spring 403 and the second spring 406 .

[0034] Since the first spring 403 and the second spring 406 are both provided with a damping mechanism, the first spring 403 and the second spring 406 can buffer the impact force during transmission.

[0035] Working principle: By twisting the locking piece 503, the hand strap 502 is in an active state, so that the length of the hand strap 502 can be adjusted. After adjusting the applicable length, the locking piece 503 is twisted in the opposite direction to lock the hand strap 502. If a collision occurs accidentally during carrying, the protective plate 401 is subjected to the impact force and drives the connecting column 402 to shrink under the action of the first spring 403. At the same time, the connecting column 402 drives the movable rod 404 to be squeezed to both sides, so that the movable rod 404 squeezes the moving block 405, and the moving block 405 moves to squeeze the second spring 406. Therefore, under the action of the first spring 403 and the second spring 406, the impact force is effectively decomposed, thereby protecting the calibrator body 3, avoiding errors after the calibrator body 3 receives the impact force, and improving the safety of the device.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
