Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, specifically a fixed structure for a RoHS testing instrument. Background Technology

[0002] RoHS testing instruments are the testing instruments that meet the EU RoHS testing standards. The most common type of RoHS testing instrument on the market is the X-ray fluorescence analyzer, which is further divided into energy dispersive type and wavelength dispersive type. Energy dispersive type is more common on the market because its technical principle and structure are simpler than those of wavelength dispersive type.

[0003] Existing RoHS testing equipment generally includes a box and a lid. The upper surface of the box has a cavity for placing the object to be tested. After the lid is closed, the object to be tested is in a relatively sealed environment for X-ray testing.

[0004] In the prior art, for example, Chinese Patent No. CN209296622U discloses a RoHS testing instrument, including: a main body, a flip cover, a hydraulic support rod, a lifting cylinder, an electromagnet, and a magnetic strip; the upper end surface of the main body is provided with a downwardly recessed testing groove, one end of the flip cover is hinged to the back of the main body, the two sides of the flip cover and the main body are supported by the hydraulic support rod, and a magnetic strip is fitted into the lower surface of the end of the flip cover away from the hinge, the magnetic strip being made of ferromagnetic material.

[0005] The aforementioned device relies solely on a magnetic strip to ensure the seal between the cover and the box. Without a buffer when the cover is closed, this can easily cause a hard impact between the cover and the main body, potentially damaging components and failing to compensate for any minor gaps during sealing, thus affecting the sealing effect. Therefore, we propose a fixing structure for RoHS testing instruments to address these issues. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows:

[0008] A fixing structure for a RoHS detector includes a housing with a cover mounted on top. A fixing component is provided between the cover and the housing. A closing groove is provided at the opening of the housing. The fixing component includes an assembly groove located at the bottom of the closing groove. Assembly cylinders are provided on both sides of the inner cavity of the assembly groove. A rotating roller is built into each assembly cylinder. One end of the rotating roller is rotatably connected to the wall of the assembly groove. A coil spring is sleeved on the surface of the rotating roller and placed inside the assembly cylinder. A top plate is fixedly connected to one side of the assembly cylinder. A lower pressure plate is fixedly connected to the side of the assembly cylinder away from the top plate. The lower pressure plate and the top plate form a seesaw structure with the assembly cylinder as the fulcrum. A limiting seat is fixedly connected to the side of the lower pressure plate near the center of the assembly groove. An assembly seat is built into the assembly groove and is slidably connected to the wall of the assembly groove. Limiting windows are provided on both sides of the assembly seat. The limiting seat is slidably connected to the inner wall of the limiting window. The top of the assembly seat is fixedly connected to the cover.

[0009] Preferably, one side of the cover is hinged to the wall of the closing groove, and a sealing strip is fixedly connected to the wall of the closing groove.

[0010] Preferably, the assembly cylinders on both sides are symmetrically distributed along the axis of the assembly groove, and the rotating roller coincides with the axis of the assembly cylinder.

[0011] Preferably, one end of the rotating roller extends through the assembly groove to the outside of the box body.

[0012] Preferably, a locking knob is fixedly connected to one end of the rotating roller outside the box body, and the rotating roller is fixed to the box body by the locking knob.

[0013] Preferably, the rotating roller is fixed to the assembly cylinder by a coil spring, one end of the coil spring is fixedly connected to the inner wall of the assembly cylinder, and the other end of the coil spring is fixedly connected to the surface of the rotating roller.

[0014] Preferably, the bottom of the inner cavity of the assembly slot is provided with a first embedding slot to facilitate the entry of the top plate.

[0015] Preferably, the inner wall of the assembly groove is provided with a second embedding groove on both sides to facilitate the entry of the lower pressure plate.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0017] The fixing structure of the detector in this utility model includes a box and a cover. The box has a closing groove at its opening, and the cover is hinged to it. The sealing strip on the groove wall is the first line of protection. In the core fixing component, the assembly groove is located on one side of the bottom of the closing groove. Assembly cylinders are symmetrically distributed on both sides of its inner cavity, and a rotating roller is built in it. One end of the roller is rotatably connected to the groove wall, and the other end extends out of the box and connects to the locking knob. The coil spring sleeved on the rotating roller is placed inside the assembly cylinder and fixed to the cylinder wall and the roller surface. One side of the assembly cylinder is connected to a top plate, and the bottom corresponds to the first embedding groove; the other side is connected to a lower pressure plate. The two form a seesaw structure. The assembly groove wall has a second embedding groove for the lower pressure plate to enter. The limiting seat near the center of the lower pressure plate cooperates with the limiting windows on both sides of the assembly seat. The assembly seat is slidably connected to the assembly groove and the cover is fixed at the top. First, rotate the locking knob forward, and the lower pressure seat enters the second embedding groove. The cover falls naturally with the guidance of the assembly groove and the embedding groove. Then, rotate the locking knob in reverse, and the limiting seat engages with the limiting window for precise closing. The daily operation of the coil spring drives the lower pressure seat to keep the cover tight and also buffers the opening and closing collisions. The top plate withstands the impact and resists displacement in the initial stage of the cover falling. It provides double protection, excellent overall sealing and buffering, and effectively protects the equipment. Attached Figure Description

[0024] 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.

[0025] Example: Figures 1-5 As shown, this utility model provides a fixing structure for a RoHS detector, including a box body 1, a cover 2 installed on the top of the box body 1, a fixing component 3 between the cover 2 and the box body 1, a closing groove 101 opened at the opening of the box body 1, one side of the cover 2 is hinged to the groove wall of the closing groove 101, and a sealing strip 102 is fixedly connected to the groove wall of the closing groove 101. Compared with existing devices that rely solely on magnetic strips for sealing and cannot compensate for small gaps, your fixing structure, with the sealing strip 102 and the stable pressure applied by the lower pressure seat, ensures a tight fit between the cover 2 and the box body 1 in all directions. Even after long-term use or slight external vibration, it can effectively prevent dust, moisture and other impurities from entering the box body 1 and affecting the precision detection components of the RoHS detector, ensuring the accuracy and stability of the detection.

[0026] The fixing component 3 includes an assembly groove 301 located at the bottom of the closing groove 101. Assembly cylinders 302 are positioned on both sides of the inner cavity of the assembly groove 301, symmetrically distributed along the axis of the assembly groove 301. Rotating rollers 303 are housed within each assembly cylinder 302, their axes coinciding with the axis of the cylinders. One end of the rotating roller 303 is rotatably connected to the wall of the assembly groove 301, while the other end extends through the assembly groove 301 to the outside of the box body 1. A locking knob 305 is fixedly connected to the outer end of the rotating roller 303, securing it to the box body 1. A coil spring is sleeved on the surface of the rotating roller 303, placed inside the assembly cylinder 302, thus fixing the rotating roller 303 to the assembly cylinder 302. One end of the coil spring is fixed to the inner wall of the assembly cylinder 302. The device is fixedly connected, with the other end of the coil spring fixedly connected to the surface of the rotating roller 303. A top plate 306 is fixedly connected to one side of the assembly cylinder 302. A first embedding groove 307 is provided at the bottom of the inner cavity of the assembly groove 301 to facilitate the entry of the top plate 306. A lower pressure plate 308 is fixedly connected to the side of the assembly cylinder 302 away from the top plate 306. The lower pressure plate 308 and the top plate 306 form a seesaw structure with the assembly cylinder 302 as the fulcrum. A second embedding groove 310 is provided on both sides of the inner wall of the assembly groove 301 to facilitate the entry of the lower pressure plate 308. The device is equipped with a coil spring. Under normal conditions, the coil spring drives the lower pressure seat to apply downward pressure to the assembly seat 311. On the one hand, it can ensure that the cover 2 is tightly closed. On the other hand, during the opening and closing of the cover 2, the coil spring plays a buffering role, effectively avoiding hard collisions, greatly protecting the equipment components, reducing the frequency of maintenance, and extending the overall life of the equipment. In addition, the top plate 306 also plays a key anti-collision role during the closing process of the cover 2. When the cover 2 begins to fall, the top plate 306 will first contact the corresponding part inside the box 1. Since the top plate 306 is fixedly connected to the assembly cylinder 302, it has a certain supporting strength and can withstand the impact force of the cover 2 in the initial stage of falling, thereby further preventing the cover 2 from excessive displacement due to inertia, avoiding collision between the cover 2 and the internal components of the box 1, and providing double buffer protection for the precision parts of the equipment.

[0027] Furthermore, a limiting seat 309 is fixedly connected to the side of the lower pressure plate 308 near the center of the assembly groove 301. An assembly seat 311 is built into the assembly groove 301, and the assembly seat 311 is slidably connected to the groove wall of the assembly groove 301. Limiting windows 312 are opened on both sides of the assembly seat 311, and the limiting seat 309 is slidably connected to the inner wall of the limiting window 312. The top of the assembly seat 311 is fixedly connected to the cover 2. The device uses the fixing component 3 to realize the opening, closing, and sealing of the cover 2 and the box 1. By rotating the locking knob 305, the rotating roller 303 and its connected coil spring, top plate 306, lower pressure plate 308, and other components work together. When closing the cover 2, first turn the locking knob 305 forward, the lower seat enters the second embedding groove 310, the cover 2 falls naturally, and the mounting seat 311 enters the mounting groove 301. During this process, the mounting groove 301 and each embedding groove provide initial guidance for the fall of the cover 2, avoiding sudden large displacement. Then, reverse the locking knob 305, the limiting seat 309 enters the limiting window 312 and is fixed, achieving precise positioning and closing.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
