Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass grating, specifically to a fiberglass grating with a spring positioning mechanism. Background Technology

[0002] Fiberglass grating, also known as fiberglass reinforced plastic (FRP) grating, is a plate-like material with many open spaces, made of fiberglass as reinforcement and unsaturated polyester resin as the matrix, through a special processing and composite process. In existing technology, covering FRP grating is achieved by fixing a covering plate to the outer surface of the FRP grating matrix, significantly improving the overall load-bearing capacity. Covered FRP grating can be used as a support surface for floors, trench covers, platforms, ship decks, stairs, walkways, etc., in corrosive environments.

[0003] Existing fiberglass grating panels are typically fixed with a large number of bolts, which is often cumbersome and time-consuming, making it difficult to quickly position and splice them, resulting in low construction efficiency.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a fiberglass grating with a spring positioning mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a fiberglass grating with a spring positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass grating with a spring positioning mechanism, comprising a fiberglass grating base and a spring positioning mechanism. A positioning frame is fitted around the outside of the fiberglass grating base, and positioning blocks are provided on the left side and top of the positioning frame. Tenons are provided on the right side and bottom of the positioning frame. The spring positioning mechanism is located inside the fiberglass grating base and includes a drive shaft, a first bevel gear, a second bevel gear, a ball screw, a screw nut, and a locking pin. The first bevel gear is fitted around the rear end of the drive shaft, and the second bevel gear is connected to the outside of the first bevel gear. A ball screw passes through the middle of the second bevel gear, and a screw nut is connected to the outside of the ball screw. A locking pin is connected to the outside of the screw nut.

[0007] Furthermore, the front surface of the fiberglass grating substrate is provided with a front covering plate, and the rear surface of the fiberglass grating substrate is provided with a rear covering plate.

[0008] Furthermore, the number of positioning blocks and mortises is the same, and two sets of spring positioning mechanisms are provided.

[0009] Furthermore, the spring positioning mechanism also includes a hand-rubbing wheel, and the hand-rubbing wheel is sleeved on the outer front end of the transmission shaft. The hand-rubbing wheel and the bevel gear are coaxially arranged.

[0010] Furthermore, the spring positioning mechanism also includes a rotating shaft and a pawl, and the pawl is connected to the groove on the surface of the hand-rubbing wheel via the rotating shaft.

[0011] Furthermore, the spring positioning mechanism also includes a spring and a ratchet, and the outside of the pawl is connected to the spring, while the surface of the fiberglass grating substrate is fixed with a ratchet.

[0012] Furthermore, the end of the spring away from the pawl is fixedly connected to the fiberglass grating base, and the pawl and ratchet mesh with each other.

[0013] Furthermore, the drive shaft and the fiberglass grating base are rotatably connected, and the ball screw is also rotatably connected to the fiberglass grating base.

[0014] This utility model provides a fiberglass grating with a spring positioning mechanism, which has the following advantages:

[0015] 1. This utility model inserts a positioning block on one positioning frame into a mortise on another positioning frame. After holding down the pawl, the hand-rolling wheel is rotated to provide rotational force to the drive shaft and bevel gear one. The meshing of bevel gear one and bevel gear two transmits power to make the screw nut move along the outside of the ball screw, so that the locking pin is inserted into the positioning block. This allows the fiberglass grating base to be spliced ​​longitudinally or laterally. The operation is simple and the disassembly and assembly are convenient.

[0016] 2. The hand-rubbing wheel of this utility model rotates freely within its movable range with the drive shaft as the center. When the spring has elasticity, it makes the pawl mesh with the teeth of the inner ring of the ratchet to form a locked state, which can prevent the hand-rubbing wheel and the drive shaft from rotating counterclockwise, thus ensuring the stability of the two adjacent fiberglass grating panels after positioning and splicing.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, a fiberglass grating with a spring positioning mechanism includes a fiberglass grating base 1 and a spring positioning mechanism 7. A positioning frame 2 is fitted onto the outside of the fiberglass grating base 1, and positioning blocks 5 are provided on the left and top sides of the positioning frame 2. Tenons 6 are provided on the right and bottom sides of the positioning frame 2. A front covering plate 4 is provided on the front surface of the fiberglass grating base 1, and a rear covering plate 3 is provided on the rear surface of the fiberglass grating base 1. The spring positioning mechanism 7 is located inside the fiberglass grating base 1 and includes a drive shaft 701, a first bevel gear 707, and a second bevel gear 708. The transmission shaft 701 has a ball screw 709, a screw nut 710, and a retaining post 711. A bevel gear 707 is sleeved on the outer rear end of the transmission shaft 701, and a bevel gear 708 is connected to the outer side of the bevel gear 707. The ball screw 709 passes through the middle of the bevel gear 708, and a screw nut 710 is connected to the outer side of the ball screw 709. A retaining post 711 is connected to the outer side of the screw nut 710. The transmission shaft 701 and the fiberglass grating base 1 are rotatably connected, and the ball screw 709 and the fiberglass grating base 1 are rotatably connected. The number of positioning blocks 5 and tenons 6 are the same, and two sets of spring positioning mechanisms 7 are provided.

[0023] The specific operation is as follows: insert the positioning block 5 on one positioning frame 2 into the mortise 6 on another positioning frame 2, hold down the ratchet pawl 704 and rotate the hand wheel 702 to provide rotational force to the drive shaft 701 and bevel gear 1 707. Use the meshing of bevel gear 1 707 and bevel gear 2 708 to transmit power so that the screw nut 710 moves along the outside of the ball screw 709, so that the locking post 711 is inserted into the positioning block 5, so that the fiberglass grating base 1 can be spliced ​​longitudinally or laterally. The operation is simple and the disassembly and assembly are convenient.

[0024] like Figure 3As shown, the spring positioning mechanism 7 also includes a hand-rolling wheel 702, and the hand-rolling wheel 702 is sleeved on the outer front end of the transmission shaft 701. The hand-rolling wheel 702 and the bevel gear 707 are coaxially arranged. The spring positioning mechanism 7 also includes a rotating shaft 703 and a pawl 704. The pawl 704 is connected to the groove on the surface of the hand-rolling wheel 702 through the rotating shaft 703. The spring positioning mechanism 7 also includes a spring 705 and a ratchet 706. The spring 705 is connected to the outer side of the pawl 704. The ratchet 706 is fixed on the surface of the fiberglass grating base 1. The end of the spring 705 away from the pawl 704 is fixedly connected to the fiberglass grating base 1, and the pawl 704 and the ratchet 706 mesh with each other.

[0025] The specific operation is as follows: the hand-operated wheel 702 rotates freely within its range of motion with the drive shaft 701 as the center. When the spring 705 has elasticity, it causes the pawl 704 to mesh with the teeth of the inner ring of the ratchet 706, forming a locked state, which can prevent the hand-operated wheel 702 and the drive shaft 701 from rotating counterclockwise, ensuring the stability of the two adjacent fiberglass grating panels after positioning and splicing.

[0026] In summary, when using this fiberglass grating with spring positioning mechanism, the rear covering plate 3 and the front covering plate 4 are first fixed to the fiberglass grating base 1 by rivets. The positioning frame 2 enhances the overall load-bearing capacity of the fiberglass grating base 1. When it is used in building facilities where a large number of pieces need to be assembled, the positioning blocks 5 of two adjacent fiberglass gratings are inserted into the mortise 6. When the positioning block 5 is fully inserted into the mortise 6;

[0027] Pressing the pawl 704 deforms the spring 705 and rotates the handwheel 702 to provide rotational force to the drive shaft 701 and bevel gear 707. The bevel gear 707 drives the two bevel gears 708 to drive the two ball screws 709 to rotate synchronously. The screw nut 710 drives the locking post 711 to make a linear displacement along the outside of the ball screw 709 in a direction away from the drive shaft 701, so that the locking post 711 can be inserted into the groove of the positioning block 5. The two fiberglass grating panels are quickly positioned and spliced, which effectively improves the construction efficiency.

[0028] After splicing, the spring 705 applies elastic force to the pawl 704, causing the pawl 704 to rotate within its movable range around the pivot 703. The pawl 704 engages with the inner ring of the ratchet 706 to form a locking state, ensuring the stability of the adjacent fiberglass grating panels after positioning and splicing. Furthermore, since there are two sets of spring positioning mechanisms 7, the fiberglass grating panels can be spliced ​​longitudinally or laterally, facilitating large-scale paving and use.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
