Description

Technical Field

[0001] This utility model relates to the inspection of the rear frame of a walking aid, specifically a deformation inspection tool for the welded rear frame of a walking aid. Background Technology

[0002] In existing walker rear frames, a top rod and two side rods are welded together. However, during actual manufacturing, the rear frame often deforms after welding. Therefore, inspection is typically required after welding. Current methods primarily rely on measuring tools, which is extremely inefficient, particularly for batch production, and involves high labor intensity. To address this, a deformation gauge for the welded rear frame of a walker is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a deformation inspection tool for the welded rear frame of a walking aid in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a deformation inspection tool for the welded rear frame of a walker, comprising a base; characterized in that it further comprises a positioning part disposed on the base for positioning the position of the rear frame top rod on the base, and a detection part disposed on the base and located on both sides of the positioning part for detecting whether the rear frame has deformed, wherein the detection part includes a width detection part for detecting the width between the side rods on both sides of the rear frame.

[0005] A further preferred embodiment includes placement slots provided on the positioning section and the detection section for the rear frame to be placed on the positioning section and the detection section.

[0006] More preferably, the detection unit further includes a front and rear positioning unit for positioning the side rod on the base.

[0007] Further preferably, it also includes detection holes provided on the width detection section and the front and rear positioning sections for detecting only the distance between the holes on the side rod.

[0008] The beneficial effects of this utility model are as follows: With the setting of this inspection tool, after the top rod and two side rods are welded to form the rear frame of the walker, the rear frame of the walker is positioned on the positioning part and the detection part of this inspection tool. The positioning part is used for positioning, and the width detection part on the detection part is used to detect the side rods on both sides to detect whether there is any welding deformation of the rear frame. If the top rod of the rear frame is positioned in the positioning part and the side rods on both sides can be placed in the placement groove of the width positioning part, that is, the rear frame has not deformed and is a qualified product. If they cannot be placed in the placement groove, there is deformation and the rear frame is a defective product. There is no need to use measuring tools such as rulers for inspection. The batch inspection efficiency is high, the operation is simple and convenient and the labor intensity is low. The front and rear positioning parts are used to position the side rods. At the same time, the positioning parts are used to position the top rods. Then, by inserting a positioning pin through the detection hole, the distance between the two holes on the side rod is detected by observing whether the positioning pin can pass through the mounting hole on the side rod.

[0011] The following description, in conjunction with the accompanying drawings, further illustrates the deformation gauge for the welded rear frame of a walker according to this utility model.

[0012] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0013] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0014] See Figures 1-2 As shown, a deformation inspection tool for the welded rear frame of a walking aid includes a base 1; characterized in that it further includes a positioning part 2 disposed on the base 1 to position the top rod of the rear frame on the base 1, and a detection part 3 disposed on the base 1 and located on both sides of the positioning part 2 for detecting whether the rear frame has deformed. The detection part 3 includes a width detection part 31 for detecting the width between the side rods on both sides of the rear frame. With the setup of this inspection fixture, after the top rod and two side rods are welded together to form the rear frame of the walker, the rear frame of the walker is positioned on the positioning part 2 and the detection part 3 of this inspection fixture. Positioning is performed by the positioning part 2, and the width detection part 31 on the detection part 3 is used to detect whether there is any welding deformation of the rear frame. If the top rod of the rear frame is positioned in the positioning part 2, and the two side rods can be placed in the placement groove 4 of the width positioning part 2, then the rear frame has not deformed and is a qualified product. If they cannot be placed in the placement groove 4, then there is deformation and the rear frame is a defective product. There is no need to use measuring tools such as rulers for inspection. The batch inspection efficiency is high, the operation is simple and convenient, and the labor intensity is low.

[0015] In one embodiment, it further includes a placement slot 4 provided on the positioning part 2 and the detection part 3 for the rear frame to be placed on the positioning part 2 and the detection part 3; The placement slot 4 is used to limit the rear frame placed on the positioning part 2 and the detection part 3.

[0016] In one embodiment, the detection unit 3 further includes a front and rear positioning unit 2 for positioning the side rod in the front and rear positions on the base 1; It also includes a detection hole 5 provided on the width detection part 31 and the front and rear positioning parts 2 for detecting only the distance between the holes on the opposite side rod; The front and rear positioning parts 2 are used to position the front and rear positions of the side rod. At the same time, the positioning parts 2 are used to position the top rod. Then, by inserting a positioning pin through the detection hole 5, the distance between the two holes on the side rod is detected by observing whether the positioning pin can pass through the mounting hole on the side rod.

[0017] When using this utility model: After the rear frame is welded, the operator moves the rear frame onto the base 1 and limits the top rod on the rear frame to the placement groove 4 of the positioning part 2. Then, the side rods on both sides are placed into the placement groove 4 of the width detection part 31 on both sides. If the side rods on both sides can be placed into the placement groove 4, then no deformation has occurred due to welding. If the side rods cannot be completely placed into the placement groove 4, then the rear frame has deformed due to welding, and the rear frame fails the inspection. After the rear frame deformation test is passed, the operator inserts the positioning pin into the test hole 5. If the positioning pin passes through the test hole 5 and then through the test hole on the side rod, it means that the distance between the two holes on the side rod is qualified. If it cannot be inserted, it means that the distance between the two holes is unqualified and the product is unqualified.

[0018] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
