Description

Technical Field

[0001] The utility model belongs to the technical field of controllers, and in particular relates to a controller with a protective structure. Background Art

[0002] When spraying, in order to control the amount of powder sprayed, pressure, air, etc., the operator may use a controller to control the amount of powder. Therefore, it can be seen that the existing controllers basically meet people's practical needs, but the following problems still exist.

[0003] When the operator is using the controller, the operator will use the power cord to electrically connect the controller. When the operator is electrically connecting the controller, the operator connects one side of the power cord to the controller and the other side of the power cord to the plug. When the operator pulls the controller to move, the controller may drive the power cord to move. When the power cord moves too much, it may cause the power cord to fall off from the connecting plug on the controller, which may cause the controller to become unusable. For this reason, we propose a controller with a protective structure. Utility Model Content

[0004] The utility model provides a controller with a protective structure, wherein a protective sleeve is driven by a connecting ring and is arranged at the connection between a power line and a connector, so that the protective sleeve restricts the power line, and prevents the protective sleeve from falling off from the connector after being pulled, thereby improving the safety of equipment use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a controller with a protective structure, comprising a controller body, spring grooves symmetrically provided on both sides of the power connector at the end of the controller body, and storage grooves provided at the ends of the spring grooves, pull rods are embedded in the spring grooves, and springs are wound around the surfaces of the pull rods that respectively abut between the inner walls of the spring grooves and the surfaces of the pull rods, a rotating groove inserted into the storage groove is fixed to the end of the pull rod, and a rotating block is rotatably connected to the end of the rotating groove, a connecting ring that fits on the surface of the controller body is fixed to the end of the rotating block, and a protective sleeve that is sleeved on the power connector is fixed to the middle of the connecting ring, a retaining ring is sleeved on the end of the protective sleeve, and the retaining ring is slidably connected to the protective sleeve.

[0006] Furthermore, second clamping plates are symmetrically fixed to the two side ends of the connecting ring, and the surface of the second clamping plate is fitted with a first clamping plate fixed on the controller body, the surfaces of the first clamping plate and the second clamping plate are both provided with limit sleeves, and the limit sleeves are slidably connected to the second clamping plate, and positioning blocks are fixed on one side where the limit sleeve and the first clamping plate are fitted to each other, and the surfaces of the positioning blocks are provided with positioning grooves opened on the first clamping plate.

[0007] Furthermore, a traction block is fixed on one side where the limiting sleeve and the second clamping plate are in contact with each other, and the surface of the traction block is sleeved with a traction groove opened on the second clamping plate.

[0008] Furthermore, the limiting sleeves are all arranged in a "concave" shape, and the surfaces of the first clamping plate and the second clamping plate are both provided with a "convex" shaped groove matching the limiting sleeves.

[0009] Furthermore, a rotating block fixed on the connecting ring is inserted into the middle of the rotating groove, and a rotating rod fixed on the inner wall of the rotating groove is penetrated through the rotating block inserted into one side of the rotating groove.

[0010] Furthermore, a sliding block is fixed on one side where the retaining ring and the protective sleeve are in contact with each other, and a sliding groove provided on the protective sleeve is sleeved on the surface of the sliding block.

[0011] The beneficial effects of the utility model are:

[0012] 1. The controller with a protective structure is provided with a protective sleeve, a connecting ring, a rotating block, a rotating groove, a spring groove and a pull rod. When the operator pulls the protective sleeve, the protective sleeve drives the connecting ring to move, and the connecting ring drives the rotating groove to move through the rotating block. The rotating groove drives the pull rod to slide in the spring groove, so that the pull rod squeezes the spring. After the spring undergoes elastic deformation, the spring avoids the pull rod, so that the protective sleeve and the connecting ring are separated from the power connector. Subsequently, after the operator inserts the power cord into the power connector, the operator sets the protective sleeve and the connecting ring on the power cord. When the protective sleeve restricts the power cord, it prevents the operator from separating the power cord from the connector during pulling the power cord, thereby improving the safety of equipment use.

[0013] 2. The controller with a protective structure is provided with a first clamping plate, a second clamping plate and a limiting sleeve. When the operator pulls the connecting ring, the connecting ring drives the second clamping plate to move. After the second clamping plate is aligned with the first clamping plate, the operator pushes the limiting sleeve to move. The limiting sleeve is arranged on the surface of the first clamping plate and the second clamping plate, so that the first clamping plate and the second clamping plate are connected to each other, and the position of the connecting ring is fixed to prevent the protective sleeve and the connecting ring from moving randomly when in use, thereby improving the stability of the protective sleeve.

A retaining ring 4 is sleeved on the end of the protective sleeve 2, and the retaining ring 4 is slidably connected to the protective sleeve 2. When the operator needs to connect the power cord and the power connector, the operator first pulls the protective sleeve 2, and the protective sleeve 2 drives the connecting ring 3 to move. The connecting ring 3 drives the pull rod 11 to move through the rotating block 14, so that the pull rod 11 slides in the spring groove 10, and when the pull rod 11 slides in the spring groove 10, the pull rod 11 squeezes the spring 12. When the spring 12 moves by squeezing the pull rod 11, the spring 12 undergoes elastic deformation, and the spring 12 makes way for the pull rod 11, so that the pull rod 11 moves out of the spring groove 10, and the rotating groove 13 moves out of the receiving groove 20, then the operator pushes the connecting ring 3, the connecting ring 3 drives the rotating block 14 to move, the end of the rotating block 14 is penetrated by the circular through hole opened on one side of the rotating rod 19, and rotates on the surface of the rotating rod 19, so that the rotating block 14 rotates in the rotating groove 13, so that the connecting ring 3 and the protective sleeve 2 make way for the power connector, then the operator inserts the power cord into the power connector, then the operator pushes the connecting ring 3, the connecting ring 3 drives the rotating block 14 to rotate in the rotating groove 13, the connecting ring 3 drives the protective sleeve 2 to be set on the power cord, and then the operator releases the protective sleeve 2. The protective sleeve 2 no longer pulls the rotating block 14 through the connecting ring 3. After the rotating block 14 no longer pulls the pull rod 11 through the rotating rod 19 so that the rotating groove 13, the pull rod 11 no longer squeezes the spring 12, and the elastic deformation of the spring 12 is restored. The spring 12 pushes the pull rod 11 to move. The pull rod 11 pulls the rotating rod 19 to move through the rotating groove 13. The rotating rod 19 drives the rotating block 14 to move. The rotating block 14 drives the protective sleeve 2 to move through the connecting ring 3, so that the protective sleeve 2 is set at the power connector and the power cord plug, so that the protective sleeve 2 restricts the power cord to prevent the operator from separating the power cord from the connector during pulling the power cord, thereby improving the safety of equipment use.

[0027] In other embodiments, second clamping plates 9 are symmetrically fixed to both end portions of the connecting ring 3, and the surface of the second clamping plate 9 is fitted with a first clamping plate 8 welded to the controller body 1, the surfaces of the first clamping plate 8 and the second clamping plate 9 are both sleeved with a limiting sleeve 7, and the limiting sleeve 7 is slidably connected to the second clamping plate 9, and a traction block 15 is welded on one side where the limiting sleeve 7 and the second clamping plate 9 are fitted to each other, and the surface of the traction block 15 is sleeved with a traction groove 16 opened on the second clamping plate 9, and a positioning block 18 is welded on one side where the limiting sleeve 7 and the first clamping plate 8 are fitted to each other, and the surface of the positioning block 18 is sleeved with a positioning groove 17 opened on the first clamping plate 8. When the operator places the connecting ring 3 on the connecting ring 3, the connecting ring 3 drives the second clamping plate 9 to move, so that the second clamping plate 9 and the first clamping plate 8 are fitted to each other. When the operator first pulls the limiting sleeve 7 to move, the limiting sleeve 7 with The movable traction block 15 slides in the traction groove 16, and the traction block 15 slides in the traction groove 16, so that the limiting sleeve 7 can slide on the surface of the second clamping plate 9, and the limiting sleeve 7 is moved to the surface of the first clamping plate 8, and when the limiting sleeve 7 moves to the surface of the first clamping plate 8, the limiting sleeve 7 drives the positioning block 18 to move, so that the positioning block 18 is inserted into the positioning groove 17, and when the limiting sleeve 7 slides on the surface of the first clamping plate 8, the limiting sleeve 7 drives the positioning block 18 to slide in the positioning groove 17, so that the limiting sleeve 7 is sleeved on the surfaces of the second clamping plate 9 and the first clamping plate 8, and the positions of the second clamping plate 9 and the first clamping plate 8 are fixed, thereby fixing the position of the connecting ring 3, avoiding the connecting ring 3 and the protective sleeve 2 from moving at will when in use, and improving the stability of the protective sleeve 2 and the connecting ring 3 when in use.

[0028] In other embodiments, the limiting sleeve 7 is set to a "concave" shape, and the surfaces of the first clamping plate 8 and the second clamping plate 9 are both provided with a "convex" shaped groove that matches the limiting sleeve 7.
