[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0023] Reference Figure 1-4 The internal positioning automatic adjustment device disclosed in the embodiment of the utility model includes: a main frame 1, a steel plate base 2 is fixedly connected to the upper surface of the main frame 1, the steel plate base 2 is penetrated by the upper end of the trigger mechanism 4, and a supporting base frame 6 is fixedly connected to the lower surface of the main frame 1. Stacking ankles 7 are fixedly connected at the four corners of the supporting base frame 6. The supporting base frame 6 and the stacking ankles 7 cooperate with each other to avoid serious wear of the main frame 1 and improve the stability of the device after placement.
[0024] Two installation cavities 18 are arranged inside the main frame 1. The upper end of the installation cavity 18 passes through the upper surface of the main frame 1. The interior of the installation cavity 18 is slidably connected to the limit seat 3. When the device is used, the limit seat 3 is in close contact with the object. The upper surface of the steel plate base 2 and the part where the limit seat 3 contacts the object are fixedly connected with protective materials 17. The protective materials 17 reduce the wear effect between the object and the device. The end of the limit seat 3 close to the trigger mechanism 4 is fixedly connected with a wire locker 16. The wire rope 9 extends outward from the wire locker 16. The wire locker 16 improves the stability of the wire rope 9 after connection. The part of the installation cavity 18 passing through the main frame 1 provides sufficient activity space for the limit seat 3. The upper surface of the main frame 1 is fixedly connected with a reset mechanism 5. The reset mechanism 5 is fixedly connected to the end of the limit seat 3 away from the trigger mechanism 4. The reset mechanism 5 is composed of a spring hook seat 19 and a reset spring 20. The reset mechanism 5 ensures that the limit seat 3 returns to its original position after movement.
[0025] A trigger mechanism 4 is fixedly connected to the lower surface of the main frame 1, and the upper end of the trigger mechanism 4 passes through the upper surface of the main frame 1. The trigger mechanism 4 is composed of a bearing support seat 15, a fixing screw 14, a pressure spring 13, a fixing box 12, and a connecting rod 11. The bearing support seat 15 ensures that the self-adjusting mechanism is triggered after the product is seated. The fixing screw 14 has the function of integrating the bearing support seat 15 with the connecting rod 11. The pressure spring 13 provides a buffer time for the trigger mechanism 4 to prevent instantaneous gravity from destroying the structure of the trigger mechanism 4. The fixing box 12 improves the stability of the bearing support seat 15, the fixing screw 14, the pressure spring 13, and the connecting rod 11 after docking, and improves the stability of the trigger mechanism 4 after installation.
[0026] The lower ends of the connecting rod 11, the limit seat 3 and the main frame 1 are fixedly connected with a pulley 10. The pulley 10 reduces the wear effect between the components of the device and improves the service life of the components of the device itself. The opposite ends of the two limit seats 3 are fixedly connected with a wire rope 9. The wire rope 9 passes through the lower surface of the main frame 1, and the wire rope 9 passes through the main frame 1 and the pulley 10 at the lower end of the connecting rod 11 to connect the two limit seats 3. The wire rope 9 is in a straightened state. The limit seat 3, the trigger mechanism 4 and the wire rope 9 cooperate with each other to form a self-adjusting mechanism. The lower surface of the main frame 1 is provided with a lead opening 8. The wire rope 9 passes through the lead opening 8 and extends outside the installation cavity 18. The lead opening 8 provides sufficient space for the wire rope 9 to move.
[0027] Working principle: When using the device, place the object directly on top of the device, and the load-bearing support seat 15 will contact the object first. The load-bearing support seat 15 will start to fall under the influence of the gravity of the object. Since the load-bearing support seat 15 and the connecting rod 11 are integrated, the connecting rod 11 will fall with the load-bearing support seat 15. At this time, the connecting rod 11 will pull the taut wire rope 9, and the wire rope 9 will pull the two limit seats 3 to move toward the object. At this time, the effect of self-adjusting positioning can be achieved. After the object is packaged, the object is removed. The load-bearing support seat 15 lacks the restriction of the object's gravity and is affected by the pulling force of the reset spring 20, and the limit seat 3 is reset to its initial state.
[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
