DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0032] like Figure 1-10As shown, the utility model provides a guide rail assembly suitable for a telescopic box, including a guide rail groove 31 and a guide rail 32. The guide rail groove 31 is fixedly arranged on the fixed box 1, and a second guide wheel 37 is symmetrically arranged on the front end groove wall thereof, and a support roller wheel 34 is rotatably arranged in the front end groove, and the support roller wheel 34 is parallel to the groove bottom and is provided in multiple groups to support the guide rail 32. The guide rail 32 is fixedly connected to the telescopic box 2, and a support wheel 33 is provided at the bottom of the end thereof, and multiple groups of first guide wheels 35 are symmetrically arranged on both sides of the rear end rod body. When the telescopic box 2 is pushed or pulled, the guide rail 32 is supported by the support roller 34 and the support wheel 33 to prevent the guide rail assembly 3 from being stuck or damaged due to the excessive weight of the telescopic box 2. The second guide wheel 37 provided on the groove wall of the guide rail groove 31 and the first guide wheel 35 symmetrically provided on both sides of the rear end rod of the guide rail 32 can guide the sliding displacement of the guide rail 32. It has low requirements for processing accuracy, can effectively prevent the deformation of the telescopic box 2 and the difference in synchronization during extension and retraction, and can perform adaptive adjustment to ensure the normal operation of the guide rail assembly 3.
[0033] like Figure 1-3 As shown, in the embodiment of the utility model, the guide rail assembly 3 is provided with four groups, which are respectively provided at the top and bottom of the front end and the top and bottom of the rear end of the fixed box body 1, so that the telescopic box body 2 can extend from the side of the fixed box body 1, thereby expanding the volume of the box body and meeting the transportation needs of the assembled building. Among them, the front top and bottom of the fixed box body 1 are symmetrically provided with two groups of guide rails 32, and the front top and bottom of the fixed box body 1 are symmetrically provided with two groups of guide rail grooves 31; the top and bottom of the front end of the telescopic box body 2 are symmetrically provided with two groups of guide rails 32, and the top and bottom of the rear end of the telescopic box body 2 are symmetrically provided with two groups of guide rails 32. Through the sliding cooperation of the four groups of guide rails 32 and the guide rail grooves 31, the vertical displacement and horizontal longitudinal displacement of the telescopic box body 2 can be limited, so that the telescopic box body 2 maintains a lateral linear displacement and can smoothly slide out or retract from the fixed box body 1.
[0034] like Figure 4-8As shown, the guide rail groove 31 is made of channel steel and is a U-shaped structure, and its bottom is welded and fixed on the fixed box 1. In order to support the guide rail 32 and ensure that the guide rail 32 can move smoothly, a support roller 34 is also rotatably provided in the front end groove of the guide rail groove 31; the support roller 34 is provided with multiple groups at intervals, and the rotating shafts at both ends are rotatably provided in the mounting holes 311 opened on the groove walls on both sides of the guide rail groove 31. The top of the support roller 34 contacts the bottom of the guide rail 32, and while supporting the guide rail 32, the resistance in operation is reduced by rolling friction, ensuring the smooth displacement of the guide rail 32. Further, in order to prevent the guide rail 32 from deflecting when sliding out of the guide rail groove 31, a second guide wheel 37 is also provided at the front end exit of the guide rail groove 31. The second guide wheel 37 has two groups, which are symmetrically arranged on the front end groove wall of the guide rail groove 31, and are rotatably connected to the second mounting seat 38 through the rotating shafts at the upper and lower ends. The second mounting seat 38 is fixed to the inner groove wall of the guide rail groove 31 by welding or bolts. The second guide wheel 37 is rotatably mounted on the second mounting seat 38 to limit the two sides of the guide rail 32, and rolling friction is generated between the two to reduce the resistance during operation, thereby ensuring the smooth linear displacement of the guide rail 32. Furthermore, there is a gap of 3-5 mm between the second guide wheel 37 and the side of the guide rail 32, which can prevent the deformation of the telescopic box 2 and the difference in synchronization during telescoping, and prevent the guide rail 32 from bending and deforming and getting stuck in the guide rail groove 31.
[0035] As shown in Figures 9-10, the guide rail 32 is made of Q355 low-alloy high-strength steel, which is a square tube structure with a specification of 50*50. In order to support the guide rail 32 and ensure that the guide rail 32 can move smoothly, a support wheel 33 is provided at the bottom of the end of the guide rail 32. The support wheel 33 is rotatably arranged at the bottom of the end of the guide rail 32 through a third mounting seat, and its bottom contacts the bottom of the guide rail groove 31 to support the end of the guide rail 32. At the same time, rolling friction reduces the resistance during operation and ensures the smooth displacement of the guide rail 32. Furthermore, in order to prevent the guide rail 32 from sliding and deflecting in the guide rail groove 31, multiple groups of first guide wheels 35 are symmetrically arranged on both sides of the rear end of the guide rail 32; the first guide wheel 35 is rotatably connected to the first mounting seat 36 through the rotating shafts at the upper and lower ends, and the first mounting seat 36 is fixed on the side of the guide rail 32 by welding or bolts. The first guide wheels 35 rotatably arranged on both sides of the guide rail 32 contact the inner groove wall of the guide rail groove 31 to limit the guide rail 32, and rolling friction is generated between the two to reduce the resistance during operation, thereby ensuring the smooth linear displacement of the guide rail 32. Furthermore, there is a gap of 3-5 mm between the first guide wheel 35 and the inner groove wall of the guide rail groove 31, which can prevent the deformation of the telescopic box 2 and the difference in synchronization during telescoping, and avoid the guide rail 32 being stuck due to the bending and deformation of the guide rail groove 31.
[0036] The guide rail assembly of the present invention is provided with a support roller 34 that rotates in the front end groove of the guide rail groove 31, and a support wheel 33 that rotates at the bottom of the end of the guide rail 32, so that the bottom of the guide rail 32 can be supported. The support strength is high, which can effectively prevent the guide rail assembly 3 from being damaged due to excessive weight of the telescopic box 2. At the same time, the rolling friction of the support wheel 33 and the support roller 34 reduces the resistance during the displacement of the guide rail 32, ensures the smooth displacement of the guide rail 32, and enables the telescopic box 2 to slide out or retract smoothly from the fixed box 1.
[0037] The guide rail assembly of the present invention limits the two sides of the guide rail 32 by rotating a second guide wheel 37 at the front end exit of the guide rail groove 31, and symmetrically provides multiple groups of first guide wheels 35 on both sides of the rear end of the guide rail 32 to contact the inner groove wall of the guide rail groove 31, and utilizes rolling friction to reduce the resistance of the guide rail 32 during operation, thereby ensuring the smooth linear displacement of the guide rail 32. At the same time, there is a gap of 3-5mm between the two guide wheels 37 and the inner groove wall of the guide rail groove 31, and there is a gap of 3-5mm between the second guide wheel 37 and the side of the guide rail 32, which can prevent the deformation of the telescopic box 2 and the difference in synchronization during telescoping, so that the guide rail 32 can be adaptively adjusted to avoid the guide rail 32 from bending and deforming and getting stuck in the guide rail groove 31.
