Description

Technical Field

[0001] The utility model relates to the technical field of tools for filling materials in textiles, in particular to a push-pull type crystal sand spreading rod. Background Art

[0002] A gravity quilt is a type of quilt that is filled with additional weighted fillers, which affects human sleep by increasing the mass of the quilt. Its specific structure is as shown in the Chinese patent authorization announcement number: CN211021994U, which was announced on July 17, 2020. It is provided with: a weighted filler and a quilt body; the weighted filler is a granular filler; a plurality of weighted fillers are provided and filled in the quilt body. The purpose of increasing the weight of the quilt body by the weighted filler is achieved, thereby achieving the technical effect of being more conducive to falling asleep and ensuring sleep quality, and thus solving the technical problem of being unfavorable to falling asleep due to the quilt being too light and having no sense of oppression in the prior art. Its specification points out that the quilt body is evenly divided into a plurality of small grids; each of the small grids is filled with the weighted filler; the small grid is square in shape, and the side length is 15cm to 20cm.

[0003] However, in large-scale manufacturing, fully automated mechanized design for laying weighted fillers is prohibitively expensive. Manual laying within a defined area using a hopper is associated with limited precision and a lengthy process. I have previously designed and manufactured a crystal sand spreading rod as a solution and tool intermediate between manual and automated spreading. For details, please refer to Chinese patent application No. 2024205726381 for a crystal sand spreading rod. However, in actual use, due to the rod's length and the high mass of the crystal sand placed within it, workers are prone to fatigue during extended operations, resulting in insufficient laying precision. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to:

[0005] 1. Provide a push-pull crystal sand spreading rod to combine the spreading action with mechanical positioning, reducing the impact of worker fatigue on spreading accuracy.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a push-pull type crystal sand paving rod, comprising a paving rod and a push-pull member, a plurality of paving grooves being equidistantly arranged on the paving rod, the push-pull member being slidably connected to the paving rod, a baffle being provided on the push-pull member, a discharge port being provided on the baffle, and the position of the discharge port corresponding to the opening position of the paving groove.

[0007] This solution utilizes a push-pull mechanism mounted on the paving rod to control the flow of crystal sand into and out of the paving trough. This replaces the existing method of rotating the paving trough opening to control the flow of crystal sand. This advantageous feature is that the paving rod body can be secured by a bracket or other structure during the push-pull mechanism, ensuring that the paving trough opening position is not affected by the movement of the push-pull mechanism, thereby reducing the impact of worker fatigue on paving progress.

[0008] Optionally, the push-pull member is provided with a positioning sleeve near one end of the paving rod, an elastic member is provided in the positioning sleeve, one end of the elastic member is fixed to the positioning sleeve, and the other end of the elastic member is fixed to one end of the paving rod.

[0009] Preferably, the elastic member is a spring.

[0010] This solution uses the design of elastic parts to ensure that the paving rod keeps the paving trough closed without being affected by external forces, thus reducing the possibility of workers forgetting to close the paving trough when moving the paving rod, resulting in the spillage of crystal sand.

[0011] Optionally, the discharge port is staggered with the opening position of the paving trough when the elastic member is in a normal state, and the discharge port is aligned with the opening position of the paving trough when the elastic member is in an extended state.

[0012] When the elastic member of the present invention is in a normal state, the paving groove is closed and the crystal sand inside it does not flow out. When the elastic member is in an extended state, the paving groove is open and the crystal sand inside it can flow out, or crystal sand can be placed into the paving groove from the outside.

[0013] Optionally, the discharge port is staggered with the opening position of the paving trough when the elastic member is in a normal state, and the discharge port is aligned with the opening position of the paving trough when the elastic member is in a compressed state.

[0014] When the elastic member of the present invention is in a normal state, the paving groove is closed and the crystal sand inside it does not flow out. When the elastic member is in a contracted or compressed state, the paving groove is open and the crystal sand inside it can flow out, or crystal sand can be placed into the paving groove from the outside.

[0015] Optionally, a fixing plate is provided in the positioning sleeve, and the fixing plate is fixed in the positioning sleeve by bolt connection.

[0016] Optionally, a positioning convex plate is further provided on the positioning sleeve.

[0017] The positioning cam is used to cooperate with the external bracket. When using this equipment, the worker can click the positioning cam into the specified position, and then push and pull the paving rod to make it move relative to the push-pull member. At this time, the discharge port on the push-pull member will not move relative to the material to be laid below it. The crystal sand paving point should be confirmed based on the discharge port. In another way of use, the positioning cam can be connected to the output end of the cylinder, and the paving rod can be fixed above the material to be laid. The cylinder can drive the push-pull member and the paving rod to move relative to each other. At this time, the opening of the paving trough on the paving rod will not move relative to the material to be laid below it. The crystal sand paving point should be confirmed based on the opening.

[0018] The beneficial technical effect of this utility model is that, through the design of a push-pull member mounted on the paving rod, this solution uses a push-pull action to control the entry and exit of crystal sand in the paving trough, replacing the existing solution of controlling the entry and exit of crystal sand by rotating the paving trough opening to change its orientation. This has the advantage that during the push-pull action, the paving rod body can be fixed by a bracket or other structure, ensuring that the opening position of the paving trough is not affected by the movement of the push-pull member, thereby reducing the impact of worker fatigue on paving accuracy.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively. Example 1

[0026] Reference Figure 1 、 2 Figure 3 shows a push-pull crystal sand spreading rod. It includes a spreading rod 1 and a push-pull member. Several spreading troughs 2 are equidistantly arranged on the spreading rod 1. The push-pull member is slidably connected to the spreading rod 1. A baffle 3 is provided on the push-pull member, and a discharge port 4 is provided on the baffle 3. The position of the discharge port 4 corresponds to the opening 5 of the spreading trough 2. A positioning protrusion 8 is also provided on the positioning sleeve 6.

[0027] The push-pull member is provided with a positioning sleeve 6 at one end near the paving rod, and a spring 7 is provided in the positioning sleeve 6. One end of the spring 7 is fixed to the positioning sleeve 6, and the other end of the spring 7 is fixed to one end of the paving rod. A fixing plate 9 is provided in the positioning sleeve 6, and the fixing plate 9 is fixed in the positioning sleeve 6 by bolt connection.

[0028] The discharge port 4 is staggered with the opening 5 of the paving trough 2 when the spring 7 is in a normal state, and is aligned with the opening 5 of the paving trough 2 when the spring 7 is in an extended state.

[0029] This solution uses a push-pull part that is sleeved on the paving rod 1 to control the entry and exit of the crystal sand in the paving trough 2 by a push-pull action, thereby replacing the solution in the prior art that controls the entry and exit of the crystal sand by rotating and changing the direction of the opening 5 of the paving trough 2. Its advantage is that when the push-pull action is in progress, the paving rod 1 body can be fixed by a structure such as a bracket to ensure that the position of the opening 5 of the paving trough 2 will not be affected by the movement of the push-pull part, thereby reducing the impact of worker fatigue on the paving progress. When the spring 7 is in a normal state, the paving trough 2 is closed, and the crystal sand inside it will not flow out. When the spring 7 is in an extended state, the paving trough 2 is open, and the crystal sand inside it can flow out, or the crystal sand can be placed into the paving trough 2 from the outside.

[0030] The positioning convex plate 8 is used to cooperate with the external bracket. When using this equipment, the worker can snap the positioning convex plate 8 into the specified position, and then push and pull the paving rod 1 to make it move relative to the push-pull member. At this time, the discharge port 4 on the push-pull member will not move relative to the material to be laid below it, and the crystal sand paving point should be confirmed with the discharge port 4 as a reference. In another way of use, the positioning convex plate 8 can be connected to the output end of the cylinder, and the paving rod 1 can be fixed above the material to be laid, and the cylinder can bring the push-pull member and the paving rod 1 to move relative to each other. At this time, the opening 5 of the paving trough 2 on the paving rod 1 will not move relative to the material to be laid below it, and the crystal sand paving point should be confirmed with the opening 5 as a reference. Example 2

[0031] like Figure 4 、 5 As shown, the difference from Example 1 is that the discharge port 4 is staggered with the opening 5 of the paving trough 2 when the spring 7 is in a normal state, and the discharge port 4 is aligned with the opening 5 of the paving trough 2 when the spring 7 is in a compressed state.

[0032] When the spring 7 of this program is in normal state, the paving trough 2 is closed and the crystal sand inside it cannot flow out. When the spring 7 is in contraction or compression state, the paving trough 2 is open and the crystal sand inside it can flow out, and the crystal sand can also be placed in the paving trough 2 from the outside.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
