Abstract
Description
Technical Field
[0001] This utility model relates to the field of down and feather sampling, and specifically to a sampling mechanism for down and feather testing. Background Technology
[0002] In the down and feather loft testing process, sample preparation is crucial, requiring a sufficient quantity of down and feathers for subsequent testing. Currently, this step mainly relies on manual handling to grab down and feathers from storage bags; however, this method has significant drawbacks. Due to the lightweight nature of down and feathers, they are easily scattered by airflow during handling, which can also contaminate the testing environment to some extent. Furthermore, after handling, a large amount of down and feathers adheres to the hands, making it difficult to completely transfer them to the designated location, reducing work efficiency; moreover, repeated contact with down and feathers can easily cause skin allergies and other discomfort, causing inconvenience to operators. Therefore, developing a sampling mechanism for down and feather testing that effectively avoids the problems of down and feather scattering and sticking to hands is urgently needed. Utility Model Content
[0003] This invention provides a sampling mechanism for detecting down and feathers to address the problems of existing technologies.
[0004] The objective of this utility model can be achieved through the following technical solution: A sampling mechanism for down and feather detection includes: a sleeve, a baffle, and a clamping assembly. The baffle is elastically rotatably connected to the front opening of the sleeve. The clamping assembly includes a rod, a handle, a button, a pull rod, a spring, a claw, and a clamping plate. The rod is slidably disposed inside the sleeve. The handle is disposed at the tail end of the rod. The pull rod is slidably disposed inside the rod. The lower end of the button is rotatably connected to the handle. The upper end of the button is rotatably connected to the tail end of the pull rod. The spring is sleeved on the pull rod and located inside the rod. The claw is rotatably disposed at the front end of the rod. The lower tooth groove of the claw meshes with the second tooth groove at the front end of the pull rod. The clamping plate is fixed to the inner side of the claw. At least two sets of claws are provided.
[0005] In a further improvement, the baffle includes a circular stop block and a circular sponge block. The circular stop block is rotatably mounted on the front opening of the sleeve via a rotating shaft. A torsion spring is provided on the rotating shaft, which causes the baffle to rotate along the inside and outside of the sleeve. The circular sponge block is fixed to the outside of the circular stop block.
[0006] In a further improvement, the rod body includes a front rod body, a middle rod body, and a rear rod body connected sequentially by threads. The middle rod body has a stepped cross-section, and a limiting protrusion is provided on the outer ring of the middle rod body. A groove matching the limiting protrusion is provided inside the sleeve. The spring is located inside the cavity of the front rod body. The handle is fixedly connected to the lower middle part of the rear rod body. A relief groove is provided inside the handle. The inner side of the button is located in the relief groove. The gripper is rotatably disposed inside the front rod body.
[0007] A further improvement is that the gripper has an arc-shaped cross-section.
[0008] In a further improvement, the grippers are arranged in three sets at approximately 360° annular intervals.
[0009] Compared with existing technologies, the beneficial effects of this novel sampling mechanism for down and feather testing are as follows:
[0010] The automatic opening and closing design of the baffle and the blocking effect of the sleeve greatly reduce the possibility of down feathers escaping, maintaining a clean testing environment whether at the grabbing site or during the transfer to the measuring cylinder. Operators only need to hold the handle and operate the button. The gripper and pull rod in the clamping component are designed with toothed meshing, and multiple sets of grippers work together to stably hold down feathers, making it easy to complete the grabbing, transfer and placement of down feathers. Compared with traditional manual grabbing, down feathers will not stick to the hands, improving user comfort. Attached Figure Description

[0017] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0018] Example 1
[0019] A sampling mechanism for down and feather detection includes: a sleeve 1, a baffle 2, and a clamping assembly 3. The baffle 2 is elastically rotatably connected to the front opening 11 of the sleeve 1. The clamping assembly 3 includes a rod 31, a handle 32, a button 33, a pull rod 34, a spring 35, a gripper 36, and a clamping plate 37. The rod 31 is slidably disposed inside the sleeve 1. The handle 32 is disposed at the tail end of the rod 31. The pull rod 34 is slidably disposed inside the rod 31. The lower end of the button 33 is rotatably connected to the handle 32. The upper end of the button 33 is rotatably connected to the tail end of the pull rod 34. The spring 35 is sleeved on the pull rod 34 and located inside the rod 31. The gripper 36 is rotatably disposed at the front end of the rod 31. The lower end of the gripper 36 has a tooth groove 361 that meshes with the front end of the pull rod 34. The clamping plate 37 is fixed to the inner side of the gripper 36. The gripper 36 is provided with at least two sets.
[0020] like Figures 1-4 As shown, the working principle of this utility model is as follows:
[0021] The core of this sampling mechanism consists of a sleeve, a baffle, and a clamping assembly. The baffle is elastically rotatably connected to the front opening of the sleeve and automatically opens and closes using a rotating shaft and a torsion spring. In the clamping assembly, the rod can slide inside the sleeve, and the handle is convenient for gripping and operation. The lower end of the button is rotatably connected to the handle, and the upper end is connected to the pull rod. The pull rod slides inside the rod and is fitted with a spring. The gripper is rotatably installed at the front end of the rod, and its lower tooth groove one meshes with the front tooth groove two of the pull rod. The clamping plate is fixed inside the gripper.
[0022] First, extend the clamping assembly from the sleeve and push open the baffle. When the button is pressed inward, the lever slides backward through the lever principle. The second tooth groove of the lever interacts with the first tooth groove of the gripper, causing the gripper to rotate around the fixed point, which in turn causes the clamping plate to close and clamp the down feathers.
[0023] After the down and feathers are grasped, the clamping assembly, along with the grasped down and feathers, retracts into the sleeve. At this time, the baffle automatically rotates back to its original position under the action of the torsion spring, re-closing the front opening of the sleeve, effectively preventing the down and feathers from scattering during transfer. The operator transports the entire sampling mechanism to the measuring cylinder of the loft tester. Upon arrival, the clamping assembly is extended from the sleeve again, and its front end pushes open the baffle again. Then, the operator releases the button, and the compressed spring releases its elastic potential energy, pushing the pull rod forward to reset. The resetting motion of the pull rod, through the meshing of the teeth, drives the gripper to rotate in the opposite direction, causing the clamping plate to open and accurately place the down and feathers into the measuring cylinder.
[0024] Throughout the entire process of grabbing, transferring, and placing down and feathers, the automatic opening and closing design of the baffles and the containment function of the sleeve greatly reduce the possibility of down and feathers escaping. This maintains a clean testing environment both at the grabbing site and during transfer to the measuring cylinder.
[0025] Operators simply need to hold the handle and operate the button. The gripper and lever in the clamping assembly are designed with interlocking teeth, and multiple grippers work together to stably hold down feathers, making it easy to grasp, transfer, and place down feathers. This operation method is simple and intuitive, significantly improving work efficiency compared to traditional manual grasping, and it does not stick to the hands, improving user comfort.
[0026] As a further preferred embodiment, the baffle 2 includes a circular stop block 21 and a circular sponge block 22. The circular stop block 21 is rotatably disposed at the front end opening 11 of the sleeve 1 via a rotating shaft 211. A torsion spring 212 is provided on the rotating shaft 211, and the baffle 2 rotates along the inside and outside of the sleeve 1 via the torsion spring 212. The circular sponge block 22 is fixed to the outside of the circular stop block 21.
[0027] A circular stop is mounted on the front opening of the sleeve via a rotating shaft, with a torsion spring providing elastic force. Under normal conditions, the torsion spring causes the circular stop to seal the front opening of the sleeve. When it is necessary to clamp down or feathers, the clamping assembly slides forward, pushing the circular stop to overcome the torsion spring's elastic force and rotate outward around the shaft to open, facilitating the extension of the clamping assembly. After clamping down or feathers, the clamping assembly retracts into the sleeve, and the torsion spring resets, causing the circular stop to rotate back and close the opening. The baffle automatically opens and closes under the action of the torsion spring, eliminating the need for manual operation, simplifying the sampling process, and improving operational efficiency.
[0028] A circular sponge block surrounds the circular stop block. To ensure the smooth rotation and opening and closing of the circular stop block, the size of the circular stop block is smaller than the inner diameter of the front opening, resulting in a certain gap between the circular stop block and the front opening. The circular sponge block, due to the material properties, does not affect the opening and closing of the circular stop block. At the same time, through deformation, it can almost cover the gap and also prevent down feathers from drifting out from the gap between the circular stop block and the sleeve to a certain extent.
[0029] As a further preferred embodiment, the rod 31 includes a front rod 311, a middle rod 312, and a rear rod 313 connected sequentially by threads. The middle rod 312 has a stepped cross-section, and a limiting protrusion 314 is provided on the outer ring of the middle rod 312. The sleeve 1 has a groove inside that matches the limiting protrusion 314. The spring 35 is located inside the cavity of the front rod 311. The grip 32 is fixedly connected to the lower middle part of the rear rod 313. The grip 32 has a relief groove 321 inside, and the inner side of the button 33 is located inside the relief groove 321. The gripper 36 is rotatably disposed inside the front rod 311.
[0030] The rod body is composed of front, middle, and rear rods connected by threads, facilitating disassembly and assembly. The rod length can be adjusted according to actual usage needs, and it facilitates the insertion of the internal spring. The stepped middle rod prevents the sleeve from slipping out. A limiting protrusion on the outside of the middle rod engages with a groove inside the sleeve, limiting the sliding stroke of the rod within the sleeve and preventing rotation. The spring is housed in the front rod cavity, providing power for the pull rod to reset. A handle is fixed to the lower middle part of the rear rod for easy gripping. A recessed groove within the handle provides space for button rotation. The gripper is installed inside the front rod, moving with the rod and operating under the pull rod's drive.
[0031] As a further preferred embodiment, the gripper 36 has an arc-shaped cross-section, which can increase the space for gripping down feathers, thereby enabling it to grip more down feathers in one gripping process and improving gripping efficiency.
[0032] As a further preferred embodiment, the grippers 36 are arranged in three sets at 120-degree circumferential intervals. When the grippers open or close, they can surround and grasp the down feathers from different angles. This distribution makes the gripping force more balanced. When grasping fluffy and large down feather clumps, it can ensure that the force on each part of the down feather clump is uniform and that it is not easy to scatter.
[0033] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
