Description

Technical Field

[0001] The utility model relates to the technical field of rails, in particular to a rail that is easy to install. Background Art

[0002] Rails are metal tracks for trains to travel on, usually made of steel, connected to form a complete track system. Rail seats are supporting components installed on the railway base, located at the lower end of the rails, which play the role of supporting, fixing and adjusting the position of the rails.

[0003] The rails are pressed and fixed by the fixings inside the rail seat. However, when the rails and the rail seat are installed, two fixings need to be installed because the lower ends of the rails need to be clamped at two points at the same horizontal position. This is cumbersome and time-consuming. Therefore, we propose a rail that is easy to install to solve the existing problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the background technology and to provide a rail that is easy to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rail that is easy to install, comprising a rail body, a rail seat, a screw rod 1, a nut and a screw rod 2, a rail seat being provided at the lower end of the rail body, an assembly groove being provided inside the rail seat, a symmetrically distributed bearing seat 1 and a bearing seat 2 being provided inside the assembly groove, a screw rod 1 being rotatably plugged into the inside of the bearing seat 1, a screw rod 2 being rotatably plugged into the inside of the bearing seat 2, a bevel gear 1 and a bevel gear 2 that mesh with each other being sleeved on the outer walls of the screw rod 1 and the screw rod 2 being rotatably sleeved on the outer wall of the screw rod 2, a nut being rotatably sleeved on the outer wall of the screw rod 2, and a pressure block being provided at one end of the nut.

[0006] Preferably, a fixing rod is provided at the upper end of the rail seat, and a sliding sleeve is provided at one end of the nut, wherein the sliding sleeve is slidably sleeved on the outer wall of the fixing rod. The nut slides on the outer wall of the fixing rod through the sliding sleeve, thereby guiding the nut to slide longitudinally.

[0007] Preferably, a stopper with an outer diameter larger than the inner diameter of the nut is provided on the upper end of the second screw, so as to limit the position of the nut and prevent the nut from completely falling off the second screw.

[0008] Preferably, the screw rod 1 is provided with a rotating rod distributed in a circular array at one end outside the rail seat. When the screw rod 1 is rotated, the screw rod 1 is driven to rotate by grasping the rotating rod, and the rotation of the screw rod 1 facilitates the application of force.

[0009] Preferably, a ratchet is sleeved on the outer wall of one end of the screw located outside the rail seat, and a pawl is provided on one end of the rail seat and sleeved on the outer wall of the ratchet. When the screw rotates, the ratchet is driven to rotate. The ratchet is limited by the pawl and can only rotate in one direction. The screw rotating in the opposite direction is limited by the pawl, thereby ensuring the stability of the threaded turning part after use.

[0010] Preferably, a mounting groove is provided at the upper end of the rail seat, and a symmetrically distributed mounting seat 1 and a symmetrically distributed mounting seat 2 are provided inside both ends and the center of the mounting groove to accommodate and install the mounting seat 1 and the mounting seat 2.

[0011] Preferably, the mounting seat 1 has symmetrically distributed rollers rotatably mounted therein, a spring 1 symmetrically distributed and connected to the inner wall of the lower end of the mounting slot disposed at a lower end of the mounting seat, a through hole 1 defined within the mounting seat 1, and a guide rod 1 disposed within the spring 1 and extending through the through hole 1 on the inner wall of the lower end of the mounting slot. The rollers provide rolling support for the bottom of the rail body during reciprocating position adjustment.

[0012] Preferably, the second mounting seat has two symmetrically distributed rollers rotatably mounted therein. A lower end of the mounting seat is provided with two symmetrically distributed springs connected to the inner wall of the lower end of the mounting slot. A second through-hole is defined within the second mounting seat, and a second guide rod is provided on the inner wall of the lower end of the mounting slot, positioned within the second spring and extending through the second through-hole. The second rollers provide rolling support for the bottom of the rail body during lateral position adjustment.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model provides a rotatably installed screw rod 1 inside the rail seat, and a symmetrically distributed screw rod 2 is rotatably installed inside the rail seat. When the screw rod 1 rotates, the bevel gear 1 drives the bevel gear 2 to rotate, thereby driving the screw 2, and then the sliding guide nut is lowered. The nut drives the pressure block to clamp two points at the same horizontal position of the rail at the same time, thereby fixing the rail. The fixing process avoids the situation of separately installing two fixed parts, and the installation process is time-saving and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 5 As shown, the utility model proposes a convenient installation rail, including a rail body 1, a rail seat 2, a screw rod 3, a nut 19 and a screw rod 25. The rail body 1 is provided with a rail seat 2 at the lower end, and an assembly groove 27 is provided inside the rail seat 2. A symmetrically distributed bearing seat 1 23 and a bearing seat 2 24 are provided inside the assembly groove 27. The bearing seat 1 23 is rotatably plugged with a screw rod 3, and the bearing seat 2 24 is rotatably plugged with a screw rod 25. The outer walls of the screw rod 1 3 and the screw rod 2 25 are both sleeved with mutually meshing bevel gears 1 22 and 26. The outer wall of the screw rod 2 25 is rotatably sleeved with a nut 19, and a pressure block 4 is provided at one end of the nut 19.

[0024] A fixing rod 17 is provided at the upper end of the rail seat 2, and a sliding sleeve 18 is provided at one end of the nut 19. The sliding sleeve 18 is slidably connected to the outer wall of the fixing rod 17;

[0025] The upper end of the screw rod 25 is provided with a limit block 20 having an outer diameter greater than the inner diameter of the nut 19;

[0026] The screw rod 3 is located at one end outside the rail seat 2 and is provided with a rotating rod 21 distributed in a circular array;

[0027] The screw rod 3 is located outside the rail seat 2 and the outer wall thereof is sleeved with a ratchet 6. The rail seat 2 is provided with a pawl 28 sleeved on the outer wall of the ratchet 6 at one end.

[0028] The implementation steps based on Example 1 are as follows: the rail body 1 is placed on the upper end of the rail seat 2, and after being adjusted to the specified position, the gripping rotary rod 21 drives the screw rod 1 3 to rotate, the screw rod 1 3 drives the bevel gear 1 22 to rotate, and the bevel gear 2 26 drives the bevel gear 2 26 to rotate, driving the screw rod 2 25 to rotate. Because the nut 19 slides on the outer wall of the fixing rod 17 through the sliding sleeve 18, the nut 19 is supported for longitudinal sliding. The screw rod 2 25 drives the nut 19 to move longitudinally, and the nut 19 drives the pressure block 4 to descend. Because the two pressure blocks 4 descend at the same time, the pressure blocks 4 are driven to press and fix the two points of the rail body 1 at the same horizontal position of the rail body 1, and the use of the pressure blocks 4 of the two fixing parts is avoided, which avoids the problem of needing to fix the two fixing parts separately when pressing and fixing the two points of the rail body 1 at the same horizontal position in the traditional technology. The installation of the fixing part pressure block 4 is more time-saving and convenient to use.

[0029] When the screw 13 rotates, the ratchet 6 rotates, and the ratchet 6 rotates inside the pawl 28. After the rotation, the pawl 28 engages to prevent the screw 13 from rotating in the opposite direction. The screw 13 remains stable after rotation, so that the pressure block 4 is stable after clamping the rail.

[0030] like Figure 1-Figure 5 As shown, the utility model provides a conveniently installed rail, compared with the first embodiment, the present embodiment further includes: a mounting groove 5 is opened at the upper end of the rail seat 2, and a symmetrically distributed mounting seat 12 and a symmetrically distributed mounting seat 16 are provided inside both ends and the center of the mounting groove 5;

[0031] A symmetrically distributed roller 7 is rotatably mounted within the mounting seat 12. A symmetrically distributed spring 10 is provided at the lower end of the mounting seat 12 and connected to the inner wall of the lower end of the mounting groove 5. A through hole 11 is provided within the mounting seat 12. A guide rod 9 is provided on the inner wall of the lower end of the mounting groove 5, located inside the spring 10 and extending through the through hole 11.

[0032] A symmetrically distributed roller 8 is rotatably mounted within the second mounting seat 16. A symmetrically distributed spring 14 is provided at the lower end of the first mounting seat 12 and connected to the inner wall of the lower end of the mounting groove 5. A through hole 15 is provided within the second mounting seat 16. A guide rod 13 is provided on the inner wall of the lower end of the mounting groove 5, which is located inside the spring 14 and extends through the through hole 15.

[0033] In this embodiment, when the rail body 1 is located at the upper end of the rail seat 2, the rail body 1 performs rolling support on the lower end of the rail body 1 in a reciprocating position through the roller 1 7, and performs rolling support on the lateral position through the roller 2 8. The rail body 1 is more labor-saving when adjusting the reciprocating and lateral positions. At the same time, when the pressure block 4 moves longitudinally to press the rail body 1, the springs 10 and 214 at the lower ends of the mounting seat 12 and the mounting seat 2 16 are forced to shrink, driving the mounting seat 12 and the mounting seat 2 16 to descend, and the roller 1 7 and the roller 8 are rotated. Roller 2 8 is completely located inside the mounting groove 5, ensuring stable support at the bottom of the rail body 1. When spring 10 and spring 2 14 are in use, guide rod 1 9 slides inside through hole 11, and guide rod 2 13 slides inside through hole 2 15, guiding the telescopic spring 10 and spring 2 14, so that spring 10 and spring 2 14 are stable when they are telescopic, and the longitudinal movement of mounting seat 12 and mounting seat 2 16 is stable during use. When the rail body 1 is adjusted, the rolling support rollers 1 7 and 2 8 at the bottom are stable.

[0034] The above specific embodiments are only several preferred embodiments of the present invention.
