Description

Technical Field

[0001] This utility model relates to the field of phase voltammeter protection technology, and in particular to a phase voltammeter drop protection structure. Background Technology

[0002] A phase volt-ampere meter is a high-precision instrument used to measure the phase difference between voltage and current in a power system. It is widely used in power equipment commissioning, power quality analysis, and fault diagnosis. Its core function relies on internal precision circuit components, requiring extremely high stability in the working environment. Common phase volt-amperes are often only covered by a plastic shell or even have no covering at all, offering poor drop protection. If accidentally dropped during testing or transport, they are easily damaged.

[0003] In scenarios such as power line inspection and industrial sites, phase voltammeters are often accidentally dropped due to frequent movement or improper operation. Furthermore, the existing equipment has poor drop protection and cannot buffer against drops at corners, leading to damage to internal components or a decrease in measurement accuracy. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a drop-proof protection structure for a phase voltammeter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A phase voltammeter drop protection structure includes an instrument body and a protective structure wrapped around the instrument body for drop protection. The protective structure includes two skeletons symmetrically distributed on both sides of the instrument body. Elastic ribs corresponding to the corners of the instrument body are fixedly connected to the skeletons. Each elastic rib is fixedly connected to a drop protection gasket for protecting the instrument body.

[0007] One of the skeletons has female heads fixedly connected to both ends, and the other skeleton has male heads fixedly connected to both ends, which are matched with the female heads. The female head is threaded with a locking element for locking the male head and the female head together.

[0008] Preferably, the anti-fall pad includes a rubber sleeve fixedly mounted on the elastic rib plate, the rubber sleeve having an elastic cavity, and a plurality of first elastic rings and second elastic rings fixedly connected within the elastic cavity, the first elastic rings and second elastic rings being arranged alternately.

[0009] Preferably, the cross-section of the first elastic ring is a quadrilateral structure with two arc-shaped and concave sides, and the cross-section of the second elastic ring is a quadrilateral structure with two arc-shaped and convex sides.

[0010] Preferably, the female head has a receiving cavity, the male head can be inserted into the receiving cavity, and the end of the female head has an expansion opening distributed in a circumferential array, with a pressure plate forming between two adjacent expansion openings to apply pressure to the male head.

[0011] Preferably, the female head is fixedly provided with a threaded section, and the locking member includes an integrally formed connecting section and a fastening section. The connecting section is provided with an internal thread, and the connecting section achieves a threaded connection with the threaded section through the internal thread.

[0012] Preferably, the fastening section is a frustum-shaped component, and the surface of the pressure plate is inclined and matches the slope of the fastening section.

[0013] Preferably, the pressure plate has a plurality of spaced notches on the side facing the male end, and protrusions that increase friction are formed between adjacent notches.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this application, the corners of the instrument body are wrapped by the symmetrically arranged frame and the elastic ribs on the frame, and the impact force during the fall is dispersed by the anti-drop pads to reduce the impact energy and reduce the risk of damage to precision components such as circuit boards inside the instrument body, thereby playing a role in anti-drop protection.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figure 1-8 As shown, this utility model provides a drop protection structure for a phase voltammeter, including an instrument body 100 and a protective structure wrapped around the instrument body 100 for drop protection. The protective structure includes two skeletons 200 symmetrically distributed on both sides of the instrument body 100. Elastic ribs 300 corresponding to the corners of the instrument body 100 are fixedly connected to the skeletons 200. Each elastic rib 300 is fixedly connected to a drop-proof washer 400 for protecting the instrument body 100.

[0029] One of the skeletons 200 has a female head 500 fixedly connected to both ends, and the other skeleton 200 has a male head 600 that matches the female head 500 fixedly connected to both ends. The female head 500 has a locking member 700 threadedly connected to it for locking the male head 600 and the female head 500 together.

[0030] Specifically, the elastic rib 300 is wrapped around the corner of the instrument body 100 to absorb impact energy through elastic deformation. One side of the frame 200 has female heads 500 at both ends, and the other side of the frame 200 has male heads 600 at both ends. The two frames 200 are connected by being inserted and locked. The elastic rib 300 and the anti-drop washer 400 work together to absorb the impact, reduce the risk of damage to the internal components of the instrument, and play a role in preventing drops.

[0031] In this embodiment, the anti-fall pad 400 includes a rubber sleeve 401 fixedly disposed on the elastic rib plate 300. An elastic cavity 402 is provided inside the rubber sleeve 401. A plurality of first elastic rings 403 and second elastic rings 404 are fixedly connected inside the elastic cavity 402. The first elastic rings 403 and second elastic rings 404 are arranged alternately. The cross-section of the first elastic ring 403 is a quadrilateral structure with two arc-shaped and concave sides. The cross-section of the second elastic ring 404 is a quadrilateral structure with two arc-shaped and convex sides.

[0032] Specifically, the rubber sleeve 401 is made of silicone or rubber and is wrapped around the outside of the elastic rib 300 by plastic coating. When the instrument body 100 is dropped and impacted, the rubber sleeve 401 is deformed under pressure, causing the elastic cavity 402 to deform in volume. The concave sides of the first elastic ring 403 are squeezed inward and contracted, while the convex sides of the second elastic ring 404 are expanded outward. Through alternating deformation, the impact force is dispersed and the stress distribution is optimized to avoid local overload and achieve a good protective effect.

[0033] In this embodiment, the female head 500 has a receiving cavity 501, into which the male head 600 can be inserted. The end of the female head 500 has an expansion opening 502 distributed in a circumferential array. A pressure plate 503 is formed between two adjacent expansion openings 502 to apply pressure to the male head 600. A threaded section 504 is fixedly provided on the female head 500. The locking member 700 includes an integrally formed connecting section 701 and a fastening section 702. The connecting section 701 is provided with an internal thread, and the connecting section 701 is threadedly connected to the threaded section 504 through the internal thread. The fastening section 702 is a frustoconical member, and the surface of the pressure plate 503 is inclined and matches the slope of the fastening section 702.

[0034] Specifically, after inserting the male head 600 into the cavity of the female head 500, the locking member 700 is rotated so that its connecting section 701 engages with the threaded section 504. The conical slope of the fastening section 702 presses against the pressure plate 503 of the female head 500. The pressure plate 503 contracts inward under the pressure of the conical surface, thus completing the connection between the male head 600 and the female head 500.

[0035] In this embodiment, the pressure plate 503 has a plurality of spaced notches 505 on the side facing the male head 600, and protrusions 506 that increase friction are formed between adjacent notches 505.

[0036] Specifically, the protrusions 506 between the notches 505 and the surface of the male connector 600 generate friction to lock together, increasing friction and making the connection more secure.

[0037] How to use and how to work this device:

[0038] When using the device, the two symmetrically distributed skeletons 200 are attached to the left and right sides of the instrument body 100 respectively, and the elastic ribs 300 are wrapped around the corners of the instrument body 100. At this time, the male head 600 is aligned with the receiving cavity 501 of the female head 500, and the locking part 700 is rotated. Through the threaded engagement, it is gradually pushed in to lock the male head 600 and the female head 500 to complete the installation.

[0039] When the instrument body 100 is accidentally dropped, the rubber sleeve 401 of the anti-drop pad 400 contacts the ground first and deforms under force, causing the elastic cavity 402 to be squeezed and deformed. The concave sides of the first elastic ring 403 inside the elastic cavity 402 are squeezed inward and contracted, while the convex sides of the second elastic ring 404 are expanded outward. Through alternating deformation, the impact force is dispersed, preventing the impact force from being concentrated and transmitted to the inside of the instrument body 100, reducing the risk of damage to precision components such as circuit boards inside the instrument body 100, and playing a role in anti-drop protection.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
