Description

Technical Field

[0001] The utility model relates to the technical field of vehicle cross bars, in particular to an easy-to-install vehicle cross bar. Background Art

[0002] A car cross bar, also known as a roof cross bar, is an accessory installed on the roof of a car. It spans across the top of the car and allows car users to easily secure their luggage on the roof when traveling. Since some cars have less original trunk space, when more people travel, they often encounter embarrassment such as insufficient trunk space. Furthermore, when people go off-road or travel outdoors, the luggage they carry is sometimes larger, such as bicycles or folding ladders, which cannot be placed in the trunk of the car. After installing a car cross bar, the cargo and luggage can be easily secured on the roof, making great use of the car's usable space.

[0003] At present, when installing a cross bar on the roof of a car, the bases at both ends of the cross bar are generally clamped on the two longitudinal bars on the roof respectively, so as to achieve the effect of fixing the cross bar. However, from a practical point of view, the base and the cross bar are generally fixedly connected in the prior art, resulting in a fixed distance between the two bases, so that the cross bar can only be installed on the roof with a matching distance between the two longitudinal bars. Once the distance between the longitudinal bars on the roof is not matched, it is very inconvenient to install the cross bar, which increases the difficulty of installation. Utility Model Content

[0004] In order to solve the above technical problems, an easy-to-install vehicle cross bar is provided, which solves the problem that in the prior art, the base and the cross bar are generally fixedly connected, resulting in a fixed distance between the two bases. Once the distance between the roof longitudinal bars is not matched, it is very inconvenient to install the cross bar, which increases the difficulty of installation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an easy-to-install vehicle cross bar, comprising a cross bar body, two bases respectively arranged on both sides below the cross bar body, and also comprising a spacing adjustment mechanism for enhancing the applicable range of the cross bar body and a reinforcing mechanism for enhancing the firmness between the base and the cross bar body;

[0006] The spacing adjustment mechanism comprises a synchronous reverse push-pull component arranged between the two bases and a movable component arranged between the base and the crossbar body;

[0007] The reinforcing mechanism comprises a reinforcing plate arranged between the base and the crossbar body, the reinforcing plate is inclined, and two ends of the reinforcing plate are respectively detachably connected to the crossbar body and the base.

[0008] Preferably, the synchronous reverse push-pull member includes a transmission rod horizontally disposed below the crossbar main body. Threaded rods are fixed to both ends of the transmission rod. The thread directions of the two threaded rods are opposite, and threaded sleeves are threadedly connected to the ends of the threaded rods. The two threaded sleeves are perpendicularly fixed to the two bases respectively. Two rotation-support seats perpendicular to the bottom surface of the crossbar main body are symmetrically and rotatably sleeved on the middle part of the transmission rod.

[0009] Preferably, the movable member includes a movable seat slidably disposed in a U-shape on the rod body of the crossbar main body and a sliding groove horizontally formed in the rod body of the crossbar main body. The base is fixed to the bottom surface of the movable seat. A slider fixedly connected to the inner side wall of the movable seat is slidably disposed in the inner side of the sliding groove.

[0010] Preferably, insertion blocks are fixed to both ends of the reinforcing plate. A plurality of insertion openings adapted to one of the insertion blocks are equidistantly formed in the bottom surface of the crossbar main body. A slot adapted to the other insertion block is formed in the side wall of the base.

[0011] Preferably, a corrugated telescopic tube is further sleeved on the rod body of the threaded rod. One end of the corrugated telescopic tube is fixedly connected to the rotation-support seat. The other end of the corrugated telescopic tube is fixed with a circular fixing ring, and the fixing ring is tightly sleeved on the tube wall of the threaded sleeve.

[0012] Preferably, an anti-slip sleeve is tightly sleeved on the rod body of the transmission rod between the two rotation-support seats, and anti-slip lines are formed on the anti-slip sleeve.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) Through the setting of the spacing adjustment mechanism, the synchronous reverse push-pull member is used to cause the two bases to slide in the opposite directions of moving away from or approaching each other along the crossbar main body under the action of the movable member, so as to effectively adjust the spacing between the two bases, enabling the crossbar main body to be installed between two longitudinal bars with different intervals on the vehicle roof, and improving the application range and practicability of the crossbar main body;

[0015] (2) Through the setting of the strengthening mechanism, after the spacing between the two bases is adjusted by the spacing adjustment mechanism, the inclined reinforcing plate is assembled between the crossbar main body and the base. In this way, a triangular shape is formed among the reinforcing plate, the crossbar main body and the base, which can not only enhance the connection strength between the crossbar main body and the base, but also limit the position of the base after movement.

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0021] Refer to Figure 1-2 As shown, an easily installable vehicle crossbar includes a crossbar main body 1 and two bases 2 respectively arranged on both sides below the crossbar main body 1;

[0022] During use, the two bases 2 are respectively clamped on two longitudinal bars on the roof, and thus the installation of the crossbar main body 1 can be achieved.

[0023] However, in reality, the base 2 and the crossbar main body 1 are generally fixedly connected in the prior art, which leads to a fixed distance between the two bases 2, so that the crossbar main body 1 can only be installed on the roof where the distance between the two longitudinal bars is adapted. Once the distance between the roof longitudinal bars is not adapted, it is very inconvenient to install the crossbar main body 1, increasing the installation difficulty;

[0024] Therefore, refer to Figure 1 As shown, it should be noted that a distance adjustment mechanism for enhancing the applicable range of the crossbar main body 1 is further included;

[0025] The distance adjustment mechanism includes a synchronous reverse push-pull component arranged between the two bases 2 and a movable component arranged between the base 2 and the crossbar main body 1;

[0026] Through the setting of the distance adjustment mechanism, the synchronous reverse push-pull component is used to prompt the two bases 2 to slide in the opposite direction of moving away from or approaching each other along the crossbar main body 1 under the action of the movable component, thereby effectively adjusting the distance between the two bases 2, so that the crossbar main body 1 can be installed between two longitudinal bars with different intervals on the roof, improving the applicable range and practicability of the crossbar main body 1.

[0027] Furthermore, refer to Figure 2As shown, it should be noted that the synchronous reverse push-pull component includes a transmission rod 4 horizontally arranged below the crossbar main body 1. Threaded rods 14 are fixed at both ends of the transmission rod 4. The thread directions of the two threaded rods 14 are opposite, and threaded barrels 6 are threadedly connected to the ends of the threaded rods 14. The two threaded barrels 6 are perpendicularly fixed to the two bases 2 respectively. Two rotation seats 5 perpendicular to the bottom surface of the crossbar main body 1 are symmetrically and rotatably sleeved in the middle of the transmission rod 4.

[0028] Rotate the transmission rod 4 so that the two threaded rods 14 rotate synchronously. In this way, the two threaded barrels 6 can slide away from or close to each other under the corresponding thread structures, and drive the two bases 2 to move in the opposite direction, thereby adjusting the distance between the two bases 2.

[0029] Furthermore, referring to Figure 1 and Figure 2 As shown, it should be noted that the movable component includes a movable seat 3 slidably arranged in a U-shaped manner on the rod body of the crossbar main body 1 and a chute 8 horizontally opened on the rod body of the crossbar main body 1. The base 2 is fixed to the bottom surface of the movable seat 3. A slider fixedly connected to the inner side wall of the movable seat 3 is slidably arranged in the inner side of the chute 8.

[0030] Through the arrangement of the movable component, when the base 2 slides, the movable seat 3 can synchronously displace on the rod body of the crossbar main body 1, and cause the slider to slide in the chute 8, thereby effectively restricting the trajectory of the base 2 and ensuring the stability of the base 2 during movement.

[0031] Furthermore, referring to Figure 1 As shown, it should be noted that there is also a strengthening mechanism for enhancing the firmness between the base 2 and the crossbar main body 1;

[0032] The strengthening mechanism includes a strengthening plate 9 arranged between the base 2 and the crossbar main body 1. The strengthening plate 9 is inclined, and both ends of the strengthening plate 9 are detachably connected to the crossbar main body 1 and the base 2 respectively;

[0033] Through the arrangement of the strengthening mechanism, after the distance between the two bases 2 is adjusted by the distance adjustment mechanism, the inclined strengthening plate 9 is assembled between the crossbar main body 1 and the base 2. In this way, a triangle is formed among the strengthening plate 9, the crossbar main body 1 and the base 2, which can not only enhance the connection strength between the crossbar main body 1 and the base 2, but also limit the position of the base 2 after movement.

[0034] Furthermore, referring to Figure 1 As shown, it should be noted that insertion blocks 10 are fixed at both ends of the strengthening plate 9. A plurality of sockets 11 adapted to one of the insertion blocks 10 are equidistantly opened on the bottom surface of the crossbar main body 1, and a slot adapted to the other insertion block 10 is opened on the side wall of the base 2;

[0035] After the sliding adjustment of the base 2 is completed, align the insertion block 10 at one end of the reinforcement plate 9 and insert it into one of the socket openings 11, and align the insertion block 10 at the other end and insert it into the slot, so as to facilitate the installation of the reinforcement plate 9 between the crossbar main body 1 and the base 2.

[0036] Furthermore, referring to Figure 1 As shown, it is worth noting that a corrugated telescopic tube 13 is also sleeved on the rod body of the threaded rod 14. One end of the corrugated telescopic tube 13 is fixedly connected to the supply swivel base 5, and a circular fixing ring 12 is fixed at the other end of the corrugated telescopic tube 13. The fixing ring 12 is tightly sleeved on the barrel wall of the threaded barrel 6;

[0037] Through the setting of the corrugated telescopic tube 13, when the transmission rod 4 is screwed, during the process of the threaded barrel 6 sliding on the threaded rod 14, the fixing ring 12 can continuously stretch or compress the corrugated telescopic tube 13 synchronously with the threaded barrel 6. In this way, without affecting the mobility of the threaded barrel 6, the corrugated telescopic tube 13 can effectively cover and protect the threaded rod 14, preventing the threaded rod 14 from being directly exposed to the external environment and being corroded or damaged by dust and impurities in the air, which affects the transmission effect of the threaded rod 14 on the threaded barrel 6.

[0038] Furthermore, referring to Figure 1 As shown, it is worth noting that an anti-slip sleeve 7 is tightly sleeved on the rod body of the transmission rod 4 between the two supply swivel bases 5, and anti-slip lines are provided on the anti-slip sleeve 7;

[0039] Through the setting of the anti-slip sleeve 7, when manually screwing the transmission rod 4, the friction force of the human hand can be increased to avoid slipping.

[0040] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
