Description
Technical Field
[0001] This utility model belongs to the field of automotive bracket technology, specifically relating to a guide rail bracket. Background Technology
[0002] A groove or ridge made of metal or other materials is a structure that can support, fix, guide, and reduce friction of moving devices or equipment. When automotive guide rails are installed on automobiles, they need to be mounted on the vehicle using guide rail brackets.
[0003] The prior art discloses an automotive guide rail bracket, which, through the coordinated use of a bracket plate, an elastic component, a first bracket baffle, a second bracket baffle, a placement plate, fixing screw holes, mounting ear plates, and mounting screw holes, allows for the installation of guide rails of different sizes on the vehicle under the action of the bracket plate. This expands the applicability of the guide rail bracket, and the mounting ear plates and mounting screw holes facilitate the installation of two bracket plates on the vehicle.
[0004] The aforementioned guide rail bracket has certain drawbacks in use. For example, although the bracket baffle can extend and retract, the range of extension is limited, and when the guide rail is small, the bracket baffle cannot provide a clamping effect. Furthermore, the distance between the two bracket plates is adjusted via an adjusting screw, which is inconvenient. Therefore, a new guide rail bracket is proposed to solve these problems. Utility Model Content
[0005] In order to solve all or some of the above problems, the purpose of this utility model is to provide a guide rail bracket. The guide rail bracket of this utility model is easy to adjust and expands the width range of the guide rails that can be clamped.
[0006] According to one aspect of this utility model, a guide rail bracket is provided, including a mounting base fixed to an automobile. The mounting base is rotatably connected to a bidirectional lead screw. A groove is formed on the mounting base, and two movable seats are disposed within the groove. The bidirectional lead screw is threadedly connected to the two movable seats. Rotation of the bidirectional lead screw allows the two movable seats to move closer or further apart. Each movable seat is fixedly connected to a support plate, and each support plate is slidably connected to two lateral adjustment components. The sliding direction of each lateral adjustment component on the support plate is perpendicular to the axial direction of the bidirectional lead screw. The guide rail to be clamped is located between the two lateral adjustment components on each support plate. A spring is connected between the two lateral adjustment components on each support plate.
[0007] Furthermore, each of the bracket plates has a sliding groove extending from one end to the other. The two lateral adjustment components of each bracket plate are slidably connected to the corresponding sliding grooves, and the two lateral adjustment components of each bracket plate are connected by springs disposed in the corresponding sliding grooves.
[0008] Furthermore, each of the lateral adjustment components includes a slide plate and a baffle. The slide plates are respectively disposed in the corresponding slide grooves. The two slide plates of each support plate are respectively connected by the spring. Each baffle is respectively fixed on the side of the corresponding slide plate away from the spring. The plane of each baffle is parallel to the axial direction of the bidirectional lead screw. Each slide plate and the baffle fixedly connected to it form an L-shaped structure.
[0009] Furthermore, each of the bracket plates is provided with a limiting groove that communicates with the corresponding slide groove, and a limiting block is fixedly connected to one side of each of the slide plates, with each limiting block located in the corresponding limiting groove.
[0010] Furthermore, each of the baffles is slidably connected to at least one guide rod, one end of each guide rod on the slide plate is fixedly connected to a clamping plate, and the other end of each guide rod is fixedly connected to a protrusion. Each guide rod is limited on the baffle by the clamping plate and the protrusion. Each baffle is connected to a threaded rod, and one end of each threaded rod on the slide plate can contact the corresponding clamping plate.
[0011] Furthermore, each of the threaded rods has a rotating wheel fixedly connected to its other end.
[0012] Furthermore, both ends of the bidirectional lead screw extending outside the mounting base are connected to handwheels.
[0013] Furthermore, each of the bracket plates has a pad fixedly connected to its surface, and the guide rail to be clamped is placed on the pad.
[0014] Furthermore, ear plates are fixedly connected to both sides of the mounting base, and each ear plate has a through threaded hole. The mounting base is fixedly connected to the vehicle by bolts passing through the threaded holes.
[0015] As can be seen from the above technical solution, the guide rail bracket provided by this utility model has the following beneficial effects:
[0016] The guide rail bracket of this utility model can clamp smaller guide rails by setting up threaded rods, guide rods and clamping plates, thereby expanding the range of widths of guide rails that can be clamped.
[0017] The bidirectional lead screw and movable seat of this invention can be used to clamp guide rails of different lengths, and the two movable seats can be moved closer or further apart by rotating the bidirectional lead screw from one end via a handwheel, which has the advantage of convenient adjustment.
[0018] This invention features a pad between the guide rail and the support plate. The pad prevents the guide rail from being worn due to direct hard contact with the support plate, thus protecting the guide rail. Attached Figure Description

Detailed Implementation
[0023] To better understand the purpose, structure, and function of this utility model, a guide rail bracket of this utility model will be described in further detail below with reference to the accompanying drawings.
[0024] like Figure 1 , Figure 2 , Figure 3 As shown, this invention illustrates a guide rail bracket according to an embodiment of the present invention, including a mounting base 1 fixed to a car, a bidirectional lead screw 6 rotatably connected to the mounting base 1, a groove 2 provided on the mounting base 1, and two movable seats 3 disposed within the groove 2, the bidirectional lead screw 6 being threadedly connected to the two movable seats 3, the bidirectional lead screw 6 rotating to allow the two movable seats 3 to move closer or further apart; each movable seat 3 is fixedly connected to a support plate 4, each support plate 4 being slidably connected to two lateral adjustment components 5, the sliding direction of each lateral adjustment component 5 on the support plate 4 being perpendicular to the axial direction of the bidirectional lead screw 6, the guide rail to be clamped being located between the two lateral adjustment components 5 on each support plate 4; a spring 52 is connected between the two lateral adjustment components 5 on each support plate 4.
[0025] The guide rail bracket in this embodiment includes a mounting base 1, a bidirectional lead screw 6, a movable seat 3, a bracket plate 4, and a lateral adjustment component 5. The mounting base 1 is fixed to the vehicle. The mounting base 1 and the bidirectional lead screw 6 are rotatably connected, meaning that the bidirectional lead screw 6 can rotate relative to the mounting base 1. The bidirectional lead screw 6 is threadedly connected to two movable seats 3. Rotation of the bidirectional lead screw can bring the two movable seats 3 closer to each other or further away from each other. Each movable seat 3 is fixedly connected to a bracket plate 4. Therefore, rotating the bidirectional lead screw 6 can bring the two bracket plates 4 closer to each other or further away from each other.
[0026] Each support plate 4 is slidably connected to two lateral adjustment components 5, and the sliding direction of each lateral adjustment component 5 on the support plate 4 is perpendicular to the axis of the bidirectional lead screw 6. The two lateral adjustment components 5 of each support plate 4 are connected by a spring 52. Therefore, the distance between the two lateral adjustment components 5 of each support plate 4 can be adjusted by the deformation of the spring 52.
[0027] When using the guide rail bracket of this embodiment to clamp the guide rail, the length direction of the guide rail to be clamped is parallel to the axial direction of the bidirectional lead screw 6, and the width direction of the guide rail to be clamped is parallel to the sliding direction of each lateral adjustment component 5 on the bracket plate 4. By rotating the bidirectional lead screw 6 to bring the two bracket plates 4 closer to each other or further apart, guide rails of different lengths can be accommodated, so that the guide rail bracket of this embodiment can be used to clamp guide rails of different lengths. By pulling apart the two lateral adjustment components 5 of each bracket plate 4, the guide rail bracket of this embodiment can be used to clamp guide rails of different widths. After releasing the two lateral adjustment components 5 of each bracket plate 4, the restoring force of the spring 52 will cause the two lateral adjustment components 5 of each bracket plate 4 to clamp the guide rail.
[0028] In one embodiment, such as Figure 3 As shown, each support plate 4 has a sliding groove extending from one end to the other. The two lateral adjustment components 5 of each support plate 4 are slidably connected to the corresponding sliding grooves. The two lateral adjustment components 5 of each support plate 4 are connected by springs 52 set in the corresponding sliding grooves. The line connecting the two lateral adjustment components 5 on each support plate 4 is perpendicular to the axis of the bidirectional lead screw 6.
[0029] In this embodiment, each support plate 4 has a sliding groove, which extends from one end of the support plate 4 through the other end. Each sliding groove is slidably connected to two lateral adjustment components 5, and the sliding direction of each lateral adjustment component 5 in the sliding groove is perpendicular to the axis of the bidirectional lead screw 6. Therefore, the two lateral adjustment components 5 of each support plate 4 can overcome the elastic force of the spring 52 and move away from each other, so that the guide rail can be placed between the two lateral adjustment components 5. Under the elastic force of the spring 52, the two lateral adjustment components 5 of each support plate 4 can move closer to each other to clamp the guide rail. The two lateral adjustment components 5 of each support plate 4 are connected by springs 52 set in the corresponding sliding grooves.
[0030] In one embodiment, such as Figure 3 As shown, each lateral adjustment component 5 includes a slide plate 51 and a baffle 59. The slide plates 51 are respectively set in the corresponding slide grooves. The two slide plates 51 of each support plate 4 are connected by springs 52. Each baffle 59 is fixed on the side of the corresponding slide plate 51 away from the spring 52. The plane of each baffle 59 is parallel to the axis of the bidirectional lead screw 6. Each slide plate 51 and the baffle 59 fixedly connected to it form an L-shaped structure.
[0031] In this embodiment, each lateral adjustment component 5 includes a sliding plate 51 and a baffle 59. The sliding plate 51 is slidably connected to the corresponding slide groove, and the baffle 59 is connected to one end of the sliding plate 51. Each sliding plate 51 and the baffle 59 fixedly connected to it form an L-shaped structure. Specifically, when clamping the guide rail, pull the two baffles 59 corresponding to each support plate 4 away from the bidirectional lead screw 6 so that the distance between the two baffles 59 of each support plate 4 is greater than the width of the guide rail. Then, place the guide rail on the support plate 4, and finally release the baffles 59 so that the baffles 59 are clamped on the guide rail under the elastic force of the spring 52.
[0032] In one embodiment, such as Figure 3 As shown, each support plate 4 is provided with a limiting groove 53 that communicates with the corresponding slide groove, and a limiting block 54 is fixedly connected to one side of each slide plate 51. Each limiting block 54 is located in the corresponding limiting groove 53.
[0033] In this embodiment, the limiting groove 53 cooperates with the limiting block 54 on the slide plate 51. When the baffle 59 is pulled, the slide plate 51 slides in the corresponding groove, and the limiting block 54 slides in the limiting groove 53. Since the two ends of the limiting groove 53 perpendicular to the axis of the bidirectional lead screw 6 do not penetrate the support plate 4, the limiting block 54 is limited in the limiting groove 53, so the slide plate 51 cannot be pulled out of the groove. That is, the limiting groove 53 and the limiting block 54 are used to provide stable guidance and limiting for the slide plate 51.
[0034] In one embodiment, such as Figure 3As shown, each baffle 59 is slidably connected to at least one guide rod 55. One end of each guide rod 55 located on the slide plate 51 is fixedly connected to a clamping plate 56, and the other end of each guide rod 55 is fixedly connected to a protrusion. Each guide rod 55 is limited on the baffle 59 by the clamping plate 56 and the protrusion. Each baffle 59 is connected to a threaded rod 57, and one end of each threaded rod 57 located on the slide plate 51 can contact the corresponding clamping plate 56.
[0035] In this embodiment, each baffle 59 is threadedly connected to a threaded rod 57. Therefore, rotating the threaded rod 57 can change the length of the portion above the corresponding slide plate 51. Each baffle 59 is slidably connected to at least one guide rod 55. One end of the guide rod 55 on the slide plate 51 is fixedly connected to the clamping plate 56. Therefore, the cooperation of the threaded rod 57 and the guide rod 55 can adjust the position of the clamping plate 56 to change the distance between the two clamping plates 56 of each support plate 4, so as to accommodate the narrower width of the guide rail. Therefore, the configuration of this embodiment expands the width range of the guide rail clamped by the guide rail support.
[0036] To reiterate, when the spring 52 is at its original length, if the width of the guide rail is still less than the distance between the two clamping plates 56 when the clamping plate 56 is in close contact with the baffle 59, then place the guide rail on the bracket plate 4, and then rotate the threaded rod 57 to bring the two clamping plates 56 closer to each other until the two clamping plates 56 are clamped on both sides of the guide rail.
[0037] Each threaded rod 57 has a rotating wheel 58 fixedly connected to its other end. In this embodiment, the rotating wheel 58 is provided to facilitate the rotation of the threaded rod 57.
[0038] In one embodiment, both ends of the bidirectional lead screw 6 extending outside the mounting base 1 are connected to handwheels 7.
[0039] In this embodiment, the handwheel 7 is designed to facilitate the rotation of the bidirectional lead screw 6. The rotation of the bidirectional lead screw 6 causes the two moving seats 3 to move closer or further apart from each other. The bidirectional lead screw 6 has rotation relative to the mounting seat 1, but does not move along its axial direction.
[0040] In one embodiment, a pad 41 is fixedly connected to the surface of each support plate 4, and the guide rail to be clamped is placed on the pad 41.
[0041] In this embodiment, the pad 41 is fixed to the surface of each support plate 4 to prevent the guide rail to be clamped from directly contacting the support plate 4 and thus avoiding wear on the guide rail, thereby protecting the guide rail.
[0042] In one embodiment, ear plates are fixedly connected to both sides of the mounting base 1, and each ear plate has a through threaded hole. The mounting base 1 is fixedly connected to the car by bolts passing through the threaded holes.
[0043] In this embodiment, the mounting base 1 is fixedly connected to the car by bolts passing through threaded holes, which has the advantage of convenient installation.
[0044] The guide rail bracket of this utility model can clamp narrow guide rails by setting threaded rod 57, guide rod 55 and clamping plate 56, thereby expanding the width range of guide rails that can be clamped.
[0045] The bidirectional lead screw 6 and the movable seat 3 in this embodiment can be used to clamp guide rails of different lengths. The two movable seats 3 can be moved closer or further apart by rotating the bidirectional lead screw 6 from one end via the handwheel 7, which has the advantage of convenient adjustment.
[0046] In this embodiment, a pad 41 is provided between the guide rail and the support plate 4. The pad 41 avoids the direct hard contact between the guide rail and the support plate 4, thus preventing wear on the guide rail and protecting it.
[0047] When using the guide rail bracket in this embodiment to clamp the guide rail, the handwheel 7 is rotated to cause the bidirectional lead screw 6 to drive the two sets of moving seats 3 to move towards each other or away from each other, so that the distance between the two sets of bracket plates 4 matches the length of the guide rail; the spring 52 provides the pulling force for the two sets of baffles 59 to move away from each other, and by stretching the baffles 59, the spring 52 is stretched, which can adjust the distance between the baffles 59. After the spring 52 rebounds, it positions the guide rail; when the baffle 59 cannot fit against the smaller guide rail side wall after the spring 52 rebounds, the rotating wheel 58 controls the threaded rod 57 to drive the clamping plate 56 to move closer to the side wall of the guide rail, and then clamps and fixes it through the clamping plate 56.
