Description

Technical Field

[0001] This utility model belongs to the field of performance testing technology, and in particular relates to a novel electromagnetic compatibility performance tester. Background Technology

[0002] An electromagnetic compatibility (EMC) performance tester is a device used to evaluate the compatibility of electronic equipment in an electromagnetic environment. It is primarily used to measure and evaluate the electromagnetic interference (EMI) and electromagnetic susceptibility (EMS) performance of equipment. Existing EMC performance testers include a main body with clips fixedly mounted on both sides. A mounting block is fitted around each clip, and a mounting groove is formed inside the mounting block. A limit rod is slidably mounted inside the mounting groove, and a handle is fixedly mounted at one end of the limit rod. While this type of EMC performance tester allows for convenient installation of the mounting block, which protects the tester body, removing the mounting block requires the user to simultaneously pull the handle back and forth to disengage the clips, making operation inconvenient. Furthermore, prolonged use of the spring components can lead to metal fatigue, reducing spring effectiveness and requiring frequent maintenance. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel electromagnetic compatibility performance tester that can simultaneously move two stops used to fix the T-block, thereby fixing the outer shell to both sides of the tester and avoiding the use of spring components, thus reducing the frequency of maintenance.

[0004] This utility model is achieved through the following technical solution:

[0005] A novel electromagnetic compatibility performance tester includes a tester with T-shaped blocks integrated on both its left and right sides. A housing is provided on both sides of the tester, and a manually rotating stop assembly is installed inside each housing. A support plate is fixedly installed at the bottom of each housing. The manually rotating stop assembly includes stops arranged opposite each other. A sliding groove is formed on the left side of each stop, and a mounting plate is fixedly installed on the outer side of each stop. An upper rack is fixedly installed on the front of one of the upper mounting plates, and a lower rack is fixedly installed on the front of the other lower mounting plate. A gear meshes between the upper and lower racks. A connecting shaft is fixedly installed on the left side of the gear, and a handle is fixedly installed on the left side of the connecting shaft.

[0006] Preferably, each of the support plates is fixedly mounted with an installation rail at its lower part.

[0007] Preferably, each of the mounting rails has an I-beam bracket inserted into its lower part.

[0008] Preferably, the two connecting shafts pass through the two housings respectively, and the connecting shafts are mounted on the housing bearings.

[0009] Preferably, each of the housings has a guide rail fixedly installed inside, and the position of the guide rail is adapted to the slide groove.

[0010] Preferably, the stop block is slidably connected to the outer casing via a groove and a guide rail.

[0011] Preferably, the T-shaped block is positioned between two front and rear stop blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the arrangement of the stop block, slide groove, mounting plate, upper rack, lower rack, gear, connecting shaft, and handle facilitates the simultaneous movement of the two stop blocks, thereby making it easier to fix the outer casing on both sides of the tester and avoiding the use of spring components, thus reducing the frequency of maintenance.

[0014] 2. In this utility model, the setting of the support plate, mounting track, and I-beam bracket is beneficial for supporting the outer shell and the testing instrument. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 and attached Figure 2 As shown, a novel electromagnetic compatibility performance tester includes a tester 1. The tester 1 is an electromagnetic compatibility performance tester. T-shaped blocks 11 are integrated on both the left and right sides of the tester 1. Housings 2 are provided on both the left and right sides of the tester 1. A manual rotating stop block assembly 3 is installed inside each housing 2. A support plate 4 is fixedly installed at the bottom of each housing 2.

[0021] In this implementation plan, in conjunction with the appendix Figure 3 As shown, the manual rotating stop assembly 3 includes stops 31 arranged in opposite directions. Each stop 31 has a groove 32 on its left side. Each stop 31 has a mounting plate 33 fixedly installed on its outer side. An upper rack 34 is fixedly installed on the front of one of the upper mounting plates 33, and a lower rack 35 is fixedly installed on the front of the other lower mounting plate 33. A gear 36 meshes between the upper rack 34 and the lower rack 35. A connecting shaft 37 is fixedly installed on the left side of the gear 36, and a handle 38 is fixedly installed on the left side of the connecting shaft 37. When the user rotates the handle 38, the connecting shaft 37 and the gear 36 rotate, thereby causing the upper rack 34 and the lower rack 35 to move in opposite directions. This causes the stops 31 to move through the mounting plate 33. When the stops 31 move towards the center, they clamp the T-block 11, thus enabling both stops 31 to move simultaneously and fixing the outer casing 2 to both sides of the testing instrument 1.

[0022] In this embodiment, specifically, each of the support plates 4 is fixedly installed with an installation rail 5 at its lower part.

[0023] In this embodiment, specifically, each of the mounting rails 5 is fitted with an I-beam bracket 6 at its lower part.

[0024] In this embodiment, specifically, the two connecting shafts 37 pass through the two outer shells 2 respectively, and the connecting shafts 37 are mounted on the outer shells 2 with bearings.

[0025] In this embodiment, specifically, each of the outer shells 2 is fixedly installed with a guide rail inside, and the position of the guide rail is adapted to the slide groove 32.

[0026] In this embodiment, specifically, the stop block 31 is slidably connected to the outer shell 2 via the slide groove 32 and the guide rail.

[0027] In this embodiment, specifically, the T-shaped block 11 is positioned between two front and rear stop blocks 31.

[0028] Working principle

[0029] In this utility model, during installation, the outer shell 2 is placed on both sides of the tester 1. The user fixes the T-block 11 by manually rotating the stop block assembly 3, thereby fixing the outer shell 2 on both sides of the tester 1. The support plate 4 serves to support the outer shell 2, and the mounting rail 5 and the I-beam bracket 6 support the outer shell 2 and the tester 1.

[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
