Description

Technical Field

[0001] The utility model relates to the technical field of gravity quilt manufacturing, in particular to an adjustable gravity quilt sanding rod. Background Art

[0002] A gravity quilt is a type of quilt that is filled with additional weight-added fillers to affect human sleep by increasing the mass of the quilt. Its specific structure is as follows: a weight-added filler and a quilt body; the weight-added filler is a granular filler; a plurality of weight-added fillers are provided and filled in the quilt body.

[0003] The specification states that the quilt body is evenly divided into a plurality of small cells; each of the small cells is filled with the weight-increasing filler; the small cells are square in shape, and the side length is 15 cm to 20 cm.

[0004] At present, there is a new gravity quilt design scheme, whose small grid adopts a prismatic shape. The applicant has designed a gravity quilt paving device, application number 2024205726220, including a slide rail and a paving device, the paving device is arranged on the slide rail, and the paving device is provided with a paving trough, and the bottom of the paving trough is provided with paving holes that pass through from top to bottom. The design adopts a paving trough design with uniform paving holes, so that it can move above the quilt core through the slide rail during paving and lay crystal sand on the quilt core. The above-mentioned existing design cannot control the paving position of each paving point to form a staggered prism, and cannot be applied to the new gravity quilt design scheme. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to:

[0006] 1. Provide an adjustable gravity paving sand rod, based on the design of semi-automatic paving, so that adjacent paving points can adjust their relative positions to form staggered paving points, and the gravity paving after forming has small prismatic grids.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable gravity sand-paved rod, comprising a plurality of sectioned paving blocks, a paving groove is provided in the middle of the paving block, a connecting protrusion is provided at one end of the paving block, a connecting recess is provided at the other end of the paving block, the connecting protrusions correspond to the connecting recesses one by one, the connecting protrusions are arranged in a circular array around the axis of the paving block on one end of the paving block, and a plurality of the paving blocks are connected end to end to form a rotating paving rod.

[0008] The rotating paving rod of the present design is a part of the gravity sand-paving device, which includes a slide rail, a material storage trough, a bracket, a rotating paving rod and a driving motor. The material storage trough is fixedly connected to the bracket, the rotating paving rod is rotatably connected to the bracket, the bracket slides on the slide rail, the output end of the driving motor is connected to the rotating paving rod, and a first discharge port is provided at the lower end of the material storage trough, and the size of the paving trough corresponds to the size of the aforementioned first discharge port.

[0009] When in use, you first need to assemble several paving blocks into a rotating paving rod according to the required angle, and then insert the formed rotating paving rod under the storage trough until one end of it is connected to the output end of the driving motor. Then start the driving motor, rotate the designated paving trough to the designated position, and then pour crystal sand into the storage trough as the material to be laid. At this time, the crystal sand enters the part of the paving trough connected to the storage trough. After the bracket moves to the preset paving point, the driving motor drives the rotating paving rod to rotate. At this time, the paving trough rotates and gradually moves downward. The crystal sand in some paving troughs is affected by gravity and pours out of the paving trough and forms a conical paving on the gravity. The other part of the paving trough is connected to the storage trough during the rotation process, causing the crystal sand in the storage trough to enter the other part of the paving trough.

[0010] This design controls the amount of crystal sand laid at each laying point through the capacity of the paving trough, and controls the position of each laying point through the relative angle between the paving trough and its adjacent paving troughs.

[0011] Optionally, a positioning protrusion is provided on the side of the connecting protrusion far from the axis of the paving block, and a positioning recess corresponding to the positioning protrusion is provided in the connecting recess.

[0012] The design of positioning protrusions and positioning recesses can help make the connection between paving blocks more stable.

[0013] Optionally, there are eighteen connecting protrusions.

[0014] Optionally, a first connecting block is provided at one end of the rotating paving rod, a second connecting block is provided at the other end of the rotating paving rod, and a connecting end connected to the driving motor is provided on the first connecting block.

[0015] The first connecting block and the second connecting block serve as the head and tail ends of the rotating paving rod. The difference from the middle paving block is that they are not designed with connecting protrusions and connecting recesses at both ends, but only one end is provided with a connecting protrusion or a connecting recess, and the other end is designed as a cylinder for easy grip or has a keyway for connecting to the drive motor and the gear set.

[0016] Optionally, the connecting end is a keyway.

[0017] The utility model has the beneficial technical effect of controlling the amount of crystal sand laid at each laying point by the capacity of the laying trough, and controlling the position of each laying point by the relative angle between the laying trough and its adjacent laying troughs.
