Detailed Description

The grab bar mounting structure of the present invention applied to the cart will be described in further detail with reference to the following embodiments and the accompanying drawings.

Please refer to fig. 3 to 5, which are a first schematic diagram, a second schematic diagram and an explosion schematic diagram of the handrail mounting structure of the present invention.

The utility model provides a be applied to bar mounting structure of handcart, it mainly includes loading board 10, sets up in the mount pad 20 of loading board 10, rotatory setting in the bar 30 of mount pad 20, be fixed in the first gag lever post 40 of mount pad 20, removes and sets up in the second gag lever post 50 of mount pad 20 and set up in the torsional spring 60 of first gag lever post 40. In particular, the grab bar 30 is of a U-shaped structure, wherein two ends of the grab bar 30 are socially arranged on the bearing plate 10 through two mounting seats 20, respectively. The carrying plate 10 is mainly used for placing and transporting products, and the grab bar 30 is mainly used for holding hands of a human body, so that the trolley is pushed. Wherein the grab bar 30 is rotatably installed at the mount 20, thereby implementing a folding function of the grab bar 30. Wherein, first gag lever post 40 and the 50 cross sections of second gag lever post are square, when bar 30 is vertical, torsional spring 60 promotes second gag lever post 50 and upwards moves, and then make first gag lever post 40 and second gag lever post 50 press from both sides tight bar 30's both sides respectively, first gag lever post 40 and second gag lever post 50 and bar 30 face contact, it is fixed to the clamp of bar 30 to improve first gag lever post 40 and second gag lever post 50 greatly, the reinforcing is to the spacing stability of bar 30, make bar 30 closely be fixed in on the mount pad 20, effectively prevent that bar 30 from taking place to rock at handcart promotion in-process, thereby improve the result of use of handcart. Meanwhile, the cross section of the second limiting rod 50 is in the direction, so that the second limiting rod 50 is not easy to slip when being pressed or stepped on in the process of using the trolley, and an operator can conveniently use the trolley.

Further, set up the square groove 21 that matches with second gag lever post 50 on the mount pad 20, square groove 21 is worn to locate by second gag lever post 50, utilizes square groove 21 to play the guide effect to second gag lever post 50 for when bar 30 is vertical, second gag lever post 50 realizes moving towards bar 30 under the torsional spring 60 effect, realizes the fixed of bar 30, utilizes square groove 21 to realize preventing of second gag lever post 50 to twist reverse simultaneously. In a specific application, the square groove 21 is inclined upward, so that the moving direction of the second limiting rod 50 is crossed with the vertical direction of the grab bar 30, and thus, when the torsion spring 60 pushes the second limiting rod 50 to move upward in the square groove 21, the second limiting rod 50 is pressed against the grab bar 30. It should be noted that the first limiting rod 40 and the second limiting rod 50 are disposed in parallel, and the shortest distance between the first limiting rod 40 and the second limiting rod 50 is smaller than the diameter of the cross section of the grab bar 60, so as to ensure the effectiveness of clamping the grab bar 60 by the first limiting rod 40 and the second limiting rod 50. It is worth noting that the mounting seat 20 is further provided with a limiting plate 22, when the grab bar 30 is vertical, the grab bar 30 abuts against the limiting plate 22, the limiting plate 22 abuts against the grab bar 30, and the stability of the grab bar 30 on the mounting seat 20 is further enhanced. Wherein in this application, mount pad 20 designs for semi-enclosed construction, and wherein mount pad 20 has a movable opening 23, and movable opening 23 borders on with limiting plate 22, and bar 30 is in the activity of activity opening 23 internal rotation activity, adopts semi-enclosed construction to make mount pad 20's intensity more durable non-deformable, effectively strengthens the steadiness ability of mount pad 20 in the use.

Further, the torsion spring 60 includes a fixing portion 61 sleeved on the first limiting rod 40, an abutting portion 62 and a pushing portion 63 connected to the fixing portion 61, wherein the abutting portion 62 abuts against the bearing plate 10, the pushing portion 63 abuts against the second limiting rod 50, and the pushing portion 63 is compressed relative to the abutting portion 62, so that the pushing portion 63 always generates an upward acting force on the second limiting rod 50, thereby pushing the second limiting rod 50 to move upward. Specifically, the abutting portion 62 is designed to have a hook shape, so that the effectiveness of connection between the torsion spring 60 and the second limiting rod 50 is ensured, and the second limiting rod 50 is prevented from being disengaged from the torsion spring 60.

Still further, the handrail pole mounting structure still includes the plastic cover 70 of cover locating on handrail pole 30, wherein when handrail pole 30 is vertical, the plastic cover 70 and the inner wall butt of mount pad 20 effectively eliminate the clearance between mount pad 20 and the handrail pole 30, further strengthen handrail pole 30 for mount pad 20 fastening nature, simultaneously, effectively eliminate noise and the wearing and tearing that the friction produced between handrail pole 30 and the mount pad 20 when handrail pole 30 is rotatory or the handcart uses, effectively promote the use experience and the life of handcart.

The utility model also provides a handcart mainly includes preceding bar mounting structure and set up in the truckle (not shown in the figure) of loading board 10 bottom. The utility model discloses a handcart grips the bar through human hand and realizes promoting the handcart, and wherein when bar 30 is vertical, utilizes torsional spring 60 to promote the upwards removal of second gag lever post 50, and then makes first gag lever post 40 and second gag lever post 50 press from both sides tight bar 30's both sides respectively for bar 30 closely is fixed in on mount pad 20, avoids bar 30 to take place to rock, promotes the practical function of handcart.

The utility model discloses an operation principle as follows: when the handrail device is used, the second limiting rod 50 is pressed, the handrail rod 30 is rotated, the handrail rod 30 rotates relative to the installation seat 20 and rotates to a position between the first limiting rod 40 and the second limiting rod 50, then the acting force on the second limiting rod 50 is removed, the torsion spring 60 pushes the second limiting rod 50 to move upwards, and the first limiting rod 40 and the second limiting rod 50 respectively clamp two sides of the handrail rod 30, so that the handrail rod 30 is tightly fixed on the installation seat 20; when folding, the first and second position-limiting rods 40 and 50 are released from the fixing of the grab bar 30 by pressing the second position-limiting rod 50, and then the grab bar 30 is rotated until it is laid flat on the loading plate 10.

To sum up, the utility model discloses bar mounting structure is provided with the first gag lever post that is fixed in the mount pad, removes the torsional spring that sets up in the second gag lever post of mount pad and be used for promoting second gag lever post rebound, and when the bar was vertical, the torsional spring promoted the second gag lever post rebound, made first gag lever post and second gag lever post press from both sides tight bar's both sides respectively to strengthen the bar for the fixed of loading board and mount pad, avoid the handrail to take place to rock in the use, improve the result of use of handcart.
