Description

Technical Field

[0001] This utility model relates to the field of electrical testing equipment technology, and in particular to a portable electrical safety testing device. Background Technology

[0002] The lamp holder bending moment test device is a testing device specifically designed to test the structural strength and durability of lamp holders when subjected to bending moments, ensuring that the products meet safety standards. The lamp holder bending moment test device has a simple structure and is easy to carry, thus it is widely used.

[0003] When using the testing device, levers, fine-tuning weights, and coarse-tuning weights are used to adjust the force. Therefore, the lever at the fine-tuning weight end is much longer than the end where the coarse-tuning weight is set. As a result, when carrying the testing device, the lever will rotate, and the end where the fine-tuning weight is set will also rotate, causing impact to surrounding objects or people's hands, resulting in damage to surrounding objects or injury to people. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: This utility model provides the following... Figure 1-6 The portable electrical safety testing device shown includes:

[0032] Base 1;

[0033] Mounting bracket 2 is located at the top of base 1;

[0034] Lamp holder 3 is located inside the mounting bracket 2 and is used to install lamps;

[0035] Lever assembly 5 is disposed on one side of mounting bracket 2. Lever assembly 5 includes a first lever 51 and a second lever 52. One end of the first lever 51 is provided with a insertion groove, and one end of the second lever 52 is provided with a connector.

[0036] Fixing component 7 is located at the top of the base 1 and is used to fix the second lever 52 after disassembly.

[0037] The top of the base 1 is fixedly connected to the bottom of the mounting bracket 2, and the mounting bracket 2 is provided with a rotating seat 4 for driving the lamp holder 3 to rotate.

[0038] One end of the rotating seat 4 is fixedly connected with a connecting bolt 6 for connecting the rotating seat 4 and the first lever 51.

[0039] Furthermore, the base 1, mounting bracket 2, lamp holder 3, rotating seat 4, and connecting bolt 6 constitute the existing model TA-5D lamp holder bending moment tester. The lever assembly 5 is the lever of the existing tester. Coarse adjustment weights and fine adjustment weights are respectively fitted at both ends of the lever assembly 5. The length of the lever assembly 5 with fine adjustment weights is much longer than the length of the end with coarse adjustment weights. The connection method between the connecting bolt 6 and the first lever 51 is the connection technology of the existing tester.

[0040] The connector includes a snap-fit ​​block 53, one end of which is fixedly connected to one end of the second lever 52, and the snap-fit ​​block 53 is slidably inserted into the insertion slot.

[0041] Both the insertion slot and the snap-fit ​​block 53 have a T-shaped horizontal cross-section.

[0042] Furthermore, both the connector and the insertion slot are located at one end of the lever of the fine-tuning weight. The top of the insertion slot is through, but the bottom is not. The size of the locking block 53 is adapted to the insertion slot. The outer wall of the locking block 53 and the inner wall of the insertion slot are both rough surfaces. The part of the locking block 53 that contacts the second lever 52 is welded and fixed. Thus, by inserting the locking block 53 into the insertion slot, the first lever 51 and the second lever 52 can form a complete lever unit. At the same time, under the action of the locking block 53 and the rough surface of the inner wall of the insertion slot, the locking block 53 will not be easily moved out of the insertion slot. When the detector is not in use, the locking block 53 can be moved out of the insertion slot, thereby shortening the length of the lever end of the fine-tuning weight, thus preventing the second lever 52 from hitting surrounding objects. The disassembled second lever 52 can be fixed by the fixing component 7, so that when carrying the instrument, it is not necessary to carry the second lever 52 by hand, ensuring that the second lever 52 will not be lost, and making it easy to carry.

[0043] In embodiment two, the present invention provides a fixing component 7, which is applied to a portable electrical safety testing device in embodiment one. The fixing component 7 includes:

[0044] The fixing block 71 has a threaded groove on one side of its top end, a through slot on its top end, and a pressing groove on one side of its side.

[0045] Adjusting bolt 72 is threadedly connected to the threaded groove, and a circular groove is provided at the top of the base 1;

[0046] Bearing 73 is sleeved on the outer wall of the bottom of adjusting bolt 72, and bearing 73 is sleeved inside the circular groove;

[0047] The top end of the pressing strip 74 is fixedly connected to the top end of the inner wall of the pressing groove.

[0048] A limiting rod 8 is fixedly connected to the top of the base 1, and the limiting rod 8 is interlocked with the circular groove.

[0049] Furthermore, the bottom end of the limiting rod 8 is welded and fixed to the top end of the base 1. The threads on the outer wall of the adjusting bolt 72 mesh with the threads on the inner wall of the threaded groove. The size of the through slot corresponds to the size of the limiting rod 8. The inner wall of the circular groove is bonded and fixed to the outer wall of the bearing 73. The bearing 73 is fixedly sleeved on the outer wall of the bottom of the adjusting bolt 72. Thus, when the adjusting bolt 72 is rotated, under the action of thread meshing and the limitation of the limiting rod 8, the fixing block 71 can only move in a straight line in the vertical direction. The size of the pressing groove corresponds to the size of the second lever 52. The pressing strip 74 is made of rubber and is inserted into the pressing groove of the second lever 52. By rotating the adjusting bolt 72, the fixing block 71 is driven to move closer to the base 1, so that the second lever 52 and the fixing block 71 continuously press the pressing strip 74. The restoring force of the pressing strip 74 acts on the second lever 52, which can make the second lever 52 be compressed, thus making the installation more secure and preventing it from falling off.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
