Description

Technical Field

[0001] The utility model relates to the technical field of corrosion test tools, in particular to a device for quickly loading, unloading and positioning samples in a salt spray corrosion test. Background Art

[0002] The salt spray corrosion test simulates atmospheric salt spray corrosion and is primarily used to assess the corrosion resistance of products or metal materials. Chloride ions in salt spray penetrate the surface of metal materials and electrochemically react with the metal within, causing corrosion damage. The laboratory simulation principle is that the salt spray environment increases chloride concentration, accelerating the corrosion process, allowing the corrosion resistance of products to be assessed in a short period of time. The correct placement of the test sample in the salt spray corrosion test chamber is crucial to the accuracy of the test results.

[0003] However, the device used to fix the test sample in the current salt spray corrosion test chamber cannot meet the inclination of multiple standard test angles, which affects the test results. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that a device for fixing a test sample in a salt spray corrosion test chamber cannot meet the inclination of multiple standard test angles, thereby affecting the test effect.

[0005] In order to achieve the above-mentioned purpose, the present application proposes a device for quickly loading, unloading and positioning samples in a salt spray corrosion test, comprising: a storage rack installed at a lower position on two opposite side walls of a box; a positioning roller installed at an upper position on the same side wall of the box where the storage rack is installed, wherein the storage rack includes a flat portion and a slot portion arranged above the flat portion and with a toothed shape facing upward.

[0006] The device for quickly loading and unloading and positioning samples in a salt spray corrosion test of the present application provides a rack that can move in the horizontal direction, and at the same time provides a positioning roller that cooperates with the rack above the rack. By clamping one end of the test sample in a slot in the rack and passing the other end through the positioning roller, the angle of the test sample can be changed by moving the slot back and forth. This solves the problem that the device for fixing the test sample in the salt spray corrosion test chamber in the prior art cannot meet the inclination of multiple standard test angles, thereby affecting the test effect.

[0007] As an improvement to the above-mentioned plane portion of the present application, in order to achieve the horizontal movement of the storage rack, a linear groove is opened on the surface of the plane portion close to the side wall of the box body where the storage rack is installed.

[0008] As an improvement to the above-mentioned linear groove of the present application, in order to fix the storage rack on the box, a roller is provided on the side wall of the box on which the storage rack is installed, which is in the same horizontal plane as the linear groove, and the other end of the roller is connected to a roller stuck in the linear groove.

[0009] As an improvement to the above-mentioned slot portion of the present application, in order to prevent salt mist droplets from gathering on the tooth portion and causing corrosion to the storage rack, the slot portion includes: a tooth portion; a concave surface arranged at the bottom end of the slot portion; and a guide hole arranged at the lowest point of the concave surface and passing through the storage rack.

[0010] As an improvement of the above-mentioned positioning roller of the present application, in order to reduce the friction between the test sample and the positioning roller during the angle change process, the positioning roller includes a rotating shaft with its end close to the side wall of the box and a roller covered on the outer wall of the rotating shaft.

[0011] Furthermore, in order to provide power for the movement of the storage rack, the device also includes: a transmission mechanism arranged on the bottom surface of the box body.

[0012] Furthermore, in order to prevent the transmission mechanism from being affected by the salt spray environment in the salt spray test box, a sealing cover is provided to cover the transmission mechanism and the bottom surface of the box to form a closed chamber.

[0013] Furthermore, in order to transmit the output power of the transmission mechanism to the storage racks, the two storage racks arranged opposite to each other are provided with horizontally arranged transmission rods on the two surfaces thereof facing away from the side walls of the box body.

[0014] Furthermore, in order to prevent the transmission rod from rotating and causing excessive load on the roller stuck in the linear groove, a mounting platform is provided on the bottom surface of the box.

[0015] Furthermore, in order to transmit the output power of the transmission mechanism to the storage rack and achieve stability of the transmission rod and the output end of the transmission mechanism, the transmission rod passes through the mounting platform, and the output end of the transmission mechanism is connected to or passes through the mounting platform.

[0016] The beneficial effects of this application are:

[0017] 1. The device for quickly loading and unloading and positioning samples in the salt spray corrosion test of the present application is provided with a rack that can move in the horizontal direction, and a positioning roller that cooperates with the rack is provided above the rack. One end of the test sample can be clamped in the slot portion of the rack, and the other end passes through the positioning roller. The angle of the test sample can be changed by moving the slot portion back and forth. This solves the problem that the device for fixing the test sample in the salt spray corrosion test chamber in the prior art cannot meet the tilt requirements of multiple standard test angles, thereby affecting the test effect.

[0018] 2. The storage rack of the present application is provided with multiple slots, and multiple positioning rollers are installed directly above the slots, which can meet the needs of simultaneously installing several test samples at different angles. Therefore, different test samples can be installed in the same salt spray test, and each test sample can be adjusted to the optimal test angle suitable for different samples, thereby improving the efficiency of the test.

[0019] 3. The positioning roller of the present application adopts a combined structure of a rotating shaft and a roller. When adjusting the angle of the test sample, the sliding friction is converted into rolling friction through the rotation of the roller relative to the rotating shaft, thereby reducing the friction of the test sample when adjusting the angle and avoiding damage to the surface coating of the test sample, thereby improving the accuracy of the test results.

[0020] 4. The transmission mechanism of the present application can adopt a variety of methods, such as hydraulic transmission, cylinder transmission, gear rack transmission or screw transmission, and the transmission methods are diverse. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the Figures 1 to 3 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1 The present invention illustrates a device for quickly loading and unloading and positioning samples in a salt spray corrosion test. The device comprises: a box body 1; racks 2 are mounted on the lower sides of opposite side walls of the box body 1; positioning rollers 3 are mounted on the upper sides of the same side walls of the box body 1 as the racks 2, wherein the racks 2 comprise a planar portion 21 and a slot portion 22 disposed above the planar portion 21 and with teeth facing upward.

[0037] In one embodiment of the present application, the box 1 provides installation space for a device for quickly loading and unloading and positioning samples in a salt spray corrosion test, and the rack 2 and the positioning roller 3 are used to install the test samples, wherein the flat portion 21 on the rack 2 is used to position and install the rack 2, and the slot portion 22 is used to clamp one end of the test sample.

[0038] In the prior art, the device for fixing the test sample in the salt spray corrosion test chamber cannot meet the inclination of multiple standard test angles, which affects the test effect.

[0039] In this embodiment, the rapid loading and unloading and positioning device for samples in the salt spray corrosion test of the present application is provided with a rack that can be moved in the horizontal direction, and a positioning roller that cooperates with the rack is provided above the rack. One end of the test sample can be clamped in the slot portion in the rack, and the other end passes through the positioning roller. The angle of the test sample can be changed by moving the slot portion back and forth, which solves the problem that the device for fixing the test sample in the salt spray corrosion test chamber in the prior art cannot meet the inclination of multiple standard test angles, thereby affecting the test effect.

[0040] Please refer to Figure 2 In a further embodiment, a linear groove 211 is formed on the surface of the flat portion 21 close to the side wall of the box 1 where the rack 2 is installed. The linear groove 211 is arranged in the horizontal direction. By engaging the corresponding rollers or slide rails in the linear groove 211, the rack 2 can be restricted to move only in the horizontal direction.

[0041] Continue to refer to Figure 2 In a further embodiment, the side wall of the box 1 on which the rack 2 is mounted is provided with a roller 4, which is aligned with the linear groove 211. The other end of the roller 4 is connected to a roller 5, which is engaged in the linear groove 211. The roller 4 is used to secure the rack 2. The roller 5, mounted on one end of the roller 4 via a bearing, engages in the linear groove 211, enabling horizontal movement of the rack 2.

[0042] Optionally, the rack 2 uses the cooperation of the roller 5 and the slot, or other guide rails that limit the movement of the rack 2, to install and fix the rack 2 while limiting the movement of the rack 2 in the horizontal direction.

[0043] Continue to refer to Figure 2 In a further embodiment, the slot portion 22 includes a tooth portion 221, a concave surface 222 at the bottom of the slot portion 22, and a guide hole 223 located at the lowest point of the concave surface 222 and extending through the rack 2. Specifically, the concave surface 222 reduces the contact area between the bottom surface of the slot portion 22 and the test sample, thereby reducing friction between the test sample and the rack 2 when the test sample changes angle.

[0044] Furthermore, during the test, when small salt mist droplets in the air contact the surface of the test sample, they may condense into large droplets and drip from the surface of the test sample. The droplets at the bottom of the box 1 can be recycled, but the small salt mist droplets dripping onto the rack 2 can flow to the bottom surface of the box 1 through the guide hole 223 set at the bottom end of the concave surface 222, which can effectively prevent the salt mist droplets from accumulating in the card slot and protect the rack from corrosion.

[0045] Continue to refer to Figure 1 In a further embodiment, the positioning roller 3 includes a rotating shaft 31 whose end abuts against the side wall of the box 1, and a roller 32 wrapped around the outer wall of the rotating shaft 31. Specifically, the roller 32 converts the sliding friction of the test sample relative to the positioning roller 3 into rolling friction when the test sample adjusts its angle, thereby preventing the test sample surface from being damaged by friction and affecting the test results.

[0046] Furthermore, the device also includes: a transmission mechanism 6 disposed on the bottom surface of the box body 1; and a sealing cover 7 that covers the transmission mechanism 6 and forms a sealed chamber with the bottom surface of the box body 1. Specifically, to protect the transmission mechanism 6 from the influence of salt spray, the sealing cover 7 is further provided to form a sealed chamber with the bottom surface of the box body 1.

[0047] Horizontally mounted transmission rods 8 are attached to the two opposing racks 2 on their sides facing away from the sidewalls of the box 1. The output end of the transmission mechanism 6 is connected to the racks 2 via the transmission rods 8. The transmission rods 8 are horizontally mounted on the sides of the racks 2 facing away from the sidewalls of the box 1 and extend through mounting platforms 9 on the bottom of the box and through oblong holes in the sealing cover 7 to ensure stable and accurate transmission.

[0048] Optionally, the transmission mechanism 6 can adopt various modes according to actual precision requirements, such as hydraulic transmission, cylinder transmission, rack and pinion transmission or screw transmission.
