Description

Technical Field

[0001] This utility model relates to the technical field of elasticity testing, and in particular to an elasticity testing device for pajamas. Background Technology

[0002] Pajamas are garments specifically designed for sleeping, prioritizing comfort and functionality to create an optimal sleep environment. Existing pajamas include cardigan pajamas and pullover pajamas. Pullover pajamas, in particular, require a certain level of elasticity at the neckline.

[0003] To ensure that the elasticity of the pajamas meets the usage requirements, the neckline of the pajamas needs to be tested for elasticity. This test can be conducted by repeatedly stretching and relaxing the neckline to perform an elasticity fatigue test, thereby testing the elasticity performance of the pajamas.

[0004] Existing testing devices mostly use linear tensioning, which is ineffective for elastic fatigue testing and results in poor overall performance. To improve the performance of this testing device, the existing structure needs to be redesigned. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing devices, such as poor testing results and inconvenience of use, and provides a pajama elasticity testing device with good testing results and simple and convenient operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An elasticity testing device for pajamas, comprising: The top frame has several tie rods on its lower surface; The test block has at least three components. The test block is hoisted and connected to the tie rod and can reciprocate and slide. A clamping group is installed on the outer wall of the test block, and a fixing block is provided inside the top surface of the test block. An expansion mechanism is provided, which includes a power unit mounted on the top frame and an expansion block connected to the power unit. The expansion block can move vertically under the drive of the power unit. The expansion block is conical and contacts a fixed block.

[0007] This testing device includes a top frame with at least three pull rods mounted on it. Test blocks, the same number as the pull rods, are mounted on the lower ends of the pull rods and can slide horizontally with them. A clamping assembly is installed on the side wall of the test blocks to press firmly against the neckline of the pajama garment fitted onto the test blocks, ensuring a stable fit and enabling the elasticity test. The testing device is equipped with an expansion mechanism, which includes a power unit and an expansion block. The power unit is mounted on the lower surface of the top frame, and the expansion block is connected to the power unit. The power from the power unit drives the expansion block to move vertically. A fixed block is installed on the top surface of the expansion block. The expansion block has a conical structure. When the expansion block moves downward, the test block can slide outward. When the expansion block moves upward, the test block slides inward. Through the reciprocating sliding of the test block, this structure can perform an elasticity fatigue test on the neckline of pajamas. After the elasticity fatigue test is completed, the ability of the pajamas neckline to return to its original shape, i.e., whether the length of the neckline changes, can be observed. This testing method can achieve good elasticity testing results and is simple and convenient to operate.

[0008] Preferably, the test block has a lifting groove at its top, the lifting groove having a T-shaped cross-section, and a T-shaped lifting guide block at the lower end of the pull rod. The lifting guide block is slidably connected to the lifting groove, and a tension spring is connected inside the lifting groove, the tension spring being connected to the lifting guide block. Specifically, the lifting groove at the top of the test block, with its T-shaped cross-section, and the lifting guide block at the lower end of the pull rod, also with a T-shaped cross-section, allow the test block to be lifted and suspended on the pull rod when the lifting guide block is engaged in the lifting groove. This structure enables the lifting of the test block and ensures the stability of the horizontal sliding direction of the test block. Furthermore, the tension spring installed inside the lifting groove, connected to the lifting guide block, allows the outwardly expanding test block to be reset and retracted, ensuring the stability of the elasticity test.

[0009] Preferably, the test block has an installation hole at the upper end of its outer side wall and a slot in the middle of its outer side wall. The clamping assembly includes a clamping rod, which is L-shaped. The upper end of the clamping rod is installed into the installation hole. A clamping plate is connected to the inner wall of the lower end of the clamping rod. The clamping plate is arc-shaped. Several clamping rubber heads are provided on the inner wall of the clamping plate. The clamping rubber heads are hemispherical and contact the inner wall of the slot. The test block features an installation hole on its upper outer wall and a slot in the middle of the outer wall. The clamping assembly includes an L-shaped clamping rod with its top inserted into the installation hole, ensuring secure installation. A curved clamping plate with a hemispherical, rubber tip is mounted on the inner wall of the plate. During elasticity testing, the neckline of the pajamas is fitted into the slot on the test block, and the clamping tip presses firmly against the neckline. Combined with the curved shape of the clamping plate, this secures the pajamas and ensures a stable elasticity test result.

[0010] Preferably, a compression spring is connected to the bottom surface of the mounting hole, and the compression spring is connected to the compression rod. Specifically, the compression spring is connected to the inner surface of the mounting hole and to the upper end of the compression rod. This structure allows the compression rod to be elastically connected, making it easy to slip the pajamas into the slot and ensuring that the operation of slipping the pajamas into the slot is simple and convenient.

[0011] Preferably, the lower end of the side wall of the test block is provided with a clearance slope. This clearance slope facilitates the slipping of pajamas into the slot, making the operation simple and convenient.

[0012] Preferably, the power unit includes a rotary motor mounted on the lower surface of the top frame. The rotary motor is connected to a drive screw, and a threaded hole for the drive screw is provided in the middle of the expansion block. The drive screw is connected to the threaded hole. Specifically, the power unit includes a rotary motor mounted in the middle of the lower surface of the top frame. A drive screw is connected to the shaft end of the rotary motor. A threaded hole for the drive screw is provided in the middle of the expansion block, through which the drive screw passes. The rotation of the drive screw drives the expansion block to move vertically. This structure enables horizontal movement of the test block. By expanding and contracting the test block, the elasticity of the pajama neckline can be tested, ensuring the effectiveness of the elasticity test.

[0013] Preferably, a guide rod is connected to the lower end of the top frame, and a guide hole is provided on the outer expansion block, with the guide rod connected to the guide hole. Specifically, the guide rod connected to the lower end of the top frame and the guide hole on the outer expansion block, with the guide rod inserted into the guide hole, serves a guiding function. Combined with the power unit, this ensures the vertical movement of the outer expansion block, allowing the test block to slide back and forth, thus ensuring stable elasticity testing. Preferably, the upper end of the inner wall of the fixed block is provided with a guide slope, and the side wall of the expanding block is provided with an expanding slope, with the guide slope and the expanding slope in contact. The guide slope on the inner wall of the fixed block and the expanding slope on the side wall of the expanding block, in cooperation, allow the expanding block to slide outward during the test, thus achieving the elasticity test and ensuring its stable execution.

[0014] The advantages of this invention are: the pajama set is easy and convenient to install; the elasticity test results are good and the test process is stable. Attached Figure Description
