Description

Technical Field

[0001] The utility model belongs to the technical field of thermoplastic floors, and particularly relates to a performance testing device for thermoplastic floors and a fixing jig thereof. Background Art

[0002] A thermoplastic floor is a high-tech green environmental protection floor made of a thermoplastic polymer material (PE plastic) and processing aids, etc. After being uniformly mixed, it is heated and extruded into a mold device. It has the properties and characteristics of plastic and can replace wood and plastic. It is a new type of environmental protection high-tech material. After production, its performance needs to be detected. Usually, a jig is required to fix it for easy detection. Since the material of the thermoplastic floor is relatively soft, it needs to be manually tightened to make it taut during fixation. Now, a fixing jig that can automatically tighten the thermoplastic floor is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a performance testing device for thermoplastic floors and a fixing jig thereof, which solves the above problems.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A performance testing device for thermoplastic floors and a fixing jig thereof, including a housing, further including: a connecting rod assembly for adjusting the relative height of the jig; the connecting rod assembly includes a main shaft, an eccentric wheel A, an eccentric wheel B, and a push rod. The main shaft is rotatably connected to the housing in the housing. The two ends of the main shaft are respectively fixedly connected with an eccentric wheel A and an eccentric wheel B. The eccentric wheel A and the eccentric wheel B are respectively rotatably connected with a push rod through guide rods at their eccentric positions. The positions of the guide rods at the eccentric positions of the eccentric wheel A and the eccentric wheel B are opposite.

[0005] Beneficial Effects

[0006] The utility model provides a performance testing device for thermoplastic floors and a fixing jig thereof, which has the following beneficial effects compared with the prior art:

[0007] Related technicians place both ends of the thermoplastic floor between the clamping plates at both ends. At the same time, they control the motor B to start rotating, so that the motor B drives the gear B meshed with its output gear to rotate synchronously. Then, the gear B drives the screw rod fixedly connected to it to start rotating, causing the screw rod to drive the sliding cylinder threadedly connected to it to start linear motion. The sliding cylinder contracts into the sleeve along its connection with the sleeve, thereby driving the pull rod hinged at its top to move synchronously. The pull rod drives the pressure rod hinged to it to rotate with the hinge point with the sleeve as the fulcrum, so that the pressure rod drives the clamping plate hinged to it to rotate synchronously to complete the clamping of the thermoplastic floor. At this time, the related technicians start the motor A, so that the motor A drives the gear A meshed with its output gear to rotate synchronously. Then, the gear A drives the eccentric wheel A and the eccentric wheel B fixedly connected to both ends of the main shaft to rotate synchronously. Thus, the eccentric wheel A and the eccentric wheel B respectively drive the push rods rotatably connected to their eccentric parts to start rotating, so that the two push rods pull the two sleeves rotatably connected to them to start moving linearly towards each other, thereby tightening the thermoplastic floor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0015] Please refer to Figures 1 to 4 , a performance testing device for thermoplastic floors and its fixing fixture provided by an embodiment of the present utility model, includes a housing 101, and further includes:

[0016] Linkage assembly 2, used to adjust the relative height of the fixture;

[0017] The linkage assembly 2 includes a main shaft 201, an eccentric wheel A 202, an eccentric wheel B 203, and a push rod 204. The main shaft 201 is rotatably connected to the housing 101 in the housing 101. Eccentric wheel A 202 and eccentric wheel B 203 are respectively fixedly connected to both ends of the main shaft 201. The eccentric wheel A 202 and the eccentric wheel B 203 are respectively rotatably connected to a push rod 204 through guide rods at their eccentric positions. The positions of the guide rods at the eccentric positions of the eccentric wheel A 202 and the eccentric wheel B 203 are opposite.

[0018] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific housing 101 described in the above embodiment. For example, a plurality of universal wheels can be connected to the bottom of the housing 101. The purpose of this setting is to facilitate controlling the movement of the device in this way.

[0019] Specifically, a gear A 205 is fixedly connected to the main shaft 201. The gear A 205 meshes with the output gear of the motor A 206. The motor A 206 is fixedly connected to the housing 101.

[0020] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific motor A 206 described in the above embodiment. For example, the motor A 206 should have adjustable multi-stage speeds. The purpose of this setting is to facilitate controlling the speed of the main shaft 201 in this way, thereby adjusting the speed of the linear reciprocating motion of the sleeve 207.

[0021] Specifically, the other ends of the two push rods 204 are rotatably connected to the short shaft on the sleeve 207. The sleeve 207 is slidably connected to the housing 101 through a slide rail in the housing 101.

[0022] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific push rod 204 described in the above embodiment. For example, the push rod 204 should be made of integrally processed material. The purpose of this setting is to facilitate preventing the push rod 204 from being broken under force during the movement of driving the sleeve 207. And bearings are provided at both ends of its rotational connection. The purpose of this setting is to facilitate reducing the friction force during its rotation in this way.

[0023] Specifically, the sleeve 207 is hinged to the pressure rod 208 through a hinge seat thereon. The other end of the pressure rod 208 is hinged with a clamping plate 209. A fastening bolt is provided at the connection between the pressure rod 208 and the clamping plate 209. The clamping plate 209 is provided with a plurality of protrusions wrapped with soft rubber rings.

[0024] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific clamping plate 209 described in the above embodiment. For example, the clamping plate 209 can be set as a telescopic tube with stretching performance. The purpose of this setting is that when the length of the thermoplastic floor to be clamped is relatively long, the length of the clamping plate 209 can be changed by stretching the clamping plate 209, so that the length of the clamping plate 209 is adapted to the thermoplastic floor.

[0025] Specifically, the pressure rod 208 is hinged to the pull rod 301 through a hinge seat in the middle thereof. The other end of the pull rod 301 is hinged to the sliding cylinder 302 through a hinge seat on the sliding cylinder 302.

[0026] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific pull rod 301 described in the above embodiment. For example, the two hinged ends of the 30 should be further hardened and reinforced. The purpose of this setting is that when the pull rod 301 provides tension to clamp the thermoplastic floor, the pull rod 301 breaks under force, resulting in the inability to clamp the thermoplastic floor.

[0027] Specifically, the sliding cylinder 302 is slidably connected to the sleeve 207 in the cavity of the sleeve 207. A screw rod 303 is threadedly connected in the sliding cylinder 302. The other end of the screw rod 303 is rotatably connected to the sleeve 207.

[0028] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific sliding cylinder 302 described in the above embodiment. For example, a damping rubber ring is provided at the connection between the sliding cylinder 302 and the sleeve 207. The purpose of this setting is to facilitate increasing the damping when the sliding cylinder 302 slides in this way, and at the same time prevent abnormal noises from occurring during the sliding process.

[0029] Specifically, a gear B304 is fixedly connected to the screw rod 303. The gear B304 meshes with the output gear of the motor B305. The motor B305 is fixedly connected to the sleeve 207.

[0030] For the above example, those skilled in the art should be aware that when implementing the above technical solution, it is not limited to the specific motor B305 described in the above embodiments. For example, the motor B305 can be replaced with a handwheel, and the handwheel is rotatably connected to the housing 101. The purpose of this setting is to facilitate controlling the clamping force of the clamping plate 209 on the thermoplastic floor in this way to prevent the thermoplastic floor from being displaced due to insufficient clamping force.

[0031] In the embodiment of the present invention, relevant technicians place the two ends of the thermoplastic floor between the clamping plates 209 at both ends respectively, and at the same time control the motor B305 to start rotating, so that the motor B305 drives the gear B304 meshed with its output gear to rotate synchronously, so that the gear B304 drives the screw 303 fixedly connected to it to start rotating, so that the screw 303 drives the sliding cylinder 302 threadedly connected to it to start linear motion, so that the sliding cylinder 302 contracts into the sleeve 207 along its connection with the sleeve 207, thereby driving the pull rod 301 hinged to its top to move synchronously, so that the pull rod 301 drives the pressure rod 208 hinged to it to rotate with the hinge point with the sleeve 207 as the fulcrum, so that the pressure rod 208 drives the clamping plate 209 hinged to it to rotate synchronously to complete the clamping of the thermoplastic floor. At this time, the relevant technician starts the motor A206, so that the motor A206 drives the gear A205 meshed with its output gear to rotate synchronously, so that the gear A205 drives the eccentric wheel A202 and the eccentric wheel B203 fixedly connected to both ends of the main shaft 201 to rotate synchronously, so that the eccentric wheel A202 and the eccentric wheel B203 respectively drive the push rods 204 rotatably connected to their eccentric parts to start rotating, so that the two push rods 204 pull the two sleeves 207 rotatably connected to them to start moving linearly towards each other, thereby tightening the thermoplastic floor.
