Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a head structure of a support rod and a support rod. Background Art

[0002] In a construction environment, sometimes it is necessary to use a support cloth (the common material of the cloth is plastic film) to enclose the working area to isolate the working area and the non-working area, protect the staff and the public from potential hazards in the construction area, and control the noise, dust and light in the construction area to reduce the impact of construction on the surrounding environment.

[0003] In the prior art, the support rod for supporting the cloth includes a telescopic rod and a head end structure connected to the top of the telescopic rod. The head end structure mainly includes two categories:

[0004] The first category includes an upper clamping plate and a lower clamping plate. The bottom of the lower clamping plate is connected to the top end of the telescopic rod through a universal joint. Two gourd pin holes with the same orientation are arranged on the lower clamping plate. Two protruding fixing pins are arranged on the lower surface of the upper clamping plate. When in use, it is necessary to first separate the upper clamping plate from the lower clamping plate, then place the cloth (plastic film) on the upper layer of the lower clamping plate first, and then place the upper clamping plate on the upper layer of the cloth, and insert the fixing pins of the upper clamping plate into the large holes of the gourd holes of the lower clamping plate, and translate the upper clamping plate in the direction of the small holes of the gourd holes to lock it, so as to fix the edge of the cloth to the end of the telescopic rod. Then, stand the telescopic rod in the passage or room, make the upper surface of the upper clamping plate face the top wall (or ceiling) of the passage, and extend the telescopic rod until a "standing upright" support structure is formed. During the process, the universal joint adapts to different angles of the top wall of the passage. The support rod of this type of structure has the disadvantages of cumbersome operation, complexity, time-consuming and laborious.

[0005] The second type includes a non-slip top plate and side clips. There are two connecting ears provided at the bottom of the non-slip top plate, and these two connecting ears are pivotally connected to both sides of the top end of the telescopic rod by screws. The side clips are fixed to the side of the upper end of the telescopic rod. When in use, lay the blocking cloth over the top of the non-slip top plate and then clamp it with the side clips. Then, stand the telescopic rod in the passage or room with the upper surface of the upper clamping plate facing the top wall (or ceiling) of the passage. Extend the telescopic rod until a "standing upright to the sky" support structure is formed. During this process, the non-slip top plate can swing left and right relative to the telescopic rod to adapt to different angles of the top wall of the passage. For the support rod of this type of structure, although the operation is simpler than that of the first type, there are still the following disadvantages: (1) Since there are clips fixed on the side to clamp the blocking cloth, the non-slip top plate and the telescopic rod are not suitable for a universal joint connection structure and can only use the above-mentioned swing-type pivotal connection structure. The adjustable range of this structure is limited, which may cause the non-slip top plate not to be in full contact with the top wall of the passage, thus reducing the support performance. (2) When a part of the blocking cloth has already contacted the top wall of the passage, but the angles of the non-slip top plate and the top wall of the passage are inconsistent, and it is necessary to tilt the non-slip top plate in the direction away from the clip to make them consistent, the side clip will limit the swing amplitude of the non-slip top plate relative to the telescopic rod. When the amplitude is large, the blocking cloth is likely to slip out of the clip and may even damage the blocking cloth. To minimize the occurrence of the above situations as much as possible, the non-slip top plate needs to be adjusted before the telescopic rod is lifted upward so that the angle of the non-slip top plate is as close as possible to the angle of the top wall of the passage, and then extend the telescopic rod. However, even if adjustments are made in advance, during the lifting process, the non-slip top plate may still swing under the pulling force of the blocking cloth, and the problems described in (1) and (2) above will still occur.

[0045] In the prior art, the support rod for supporting the baffle 100 includes a telescopic rod 200 and a head end structure connected to the top of the telescopic rod 200. The head end structure mainly includes two categories:

[0046] The first category is such as Figure 1 and Figure 2As shown, it includes an upper splint 210 and a lower splint 220. The bottom of the lower splint 220 is connected to the top of the telescopic rod 200 through a universal joint 230. Two gourd pin holes with the same direction are provided on the lower splint 220. Two protruding fixing pins 250 are provided on the lower surface of the upper splint 210. When in use, it is necessary to first separate the upper splint 210 from the lower splint 220, then place the cloth 100 (plastic film) on the upper layer of the lower splint 220, and then place the upper splint 210 on the upper layer of the cloth 100, and insert the fixing pins 250 of the upper splint 210 into the lower splint The upper clamping plate 210 is moved horizontally in the large hole of the gourd hole 240 of the gourd hole 220 toward the small hole of the gourd hole 240 to be locked, and the edge of the cloth 100 can be fixed to the end of the telescopic rod 200. Then, the telescopic rod 200 is placed in the passage or room with the upper surface of the upper clamping plate 210 facing the top wall (or ceiling) of the passage, and the telescopic rod 200 is extended until a "sky-to-ground" support structure is formed. During the process, the universal joint 230 adapts to different angles of the top wall of the passage. The support rod of this type of structure has the disadvantages of being cumbersome, complicated, time-consuming and labor-intensive to operate.

[0047] The second category is Figure 3As shown, it includes an anti-skid top plate 300 and side clips 400. Two connecting ears 141 are provided at the bottom of the anti-skid top plate 300. The two connecting ears 141 are pivotally connected to the two sides of the top of the telescopic rod 200 by screws, and the side clips 400 are fixed to the side surfaces of the upper end of the telescopic rod 200. When in use, the blocking cloth 100 is spread over the top of the anti-skid top plate 300 and clamped with the side clips 400. Then, the telescopic rod 200 is placed in a passage or room so that the upper surface of the upper splint 210 faces the top wall (or ceiling) of the passage. The telescopic rod 200 is extended until a "sky-standing" type support structure is formed. During the process, the anti-skid top plate 300 can swing left and right relative to the telescopic rod 200 to adapt to different angles of the top wall of the passage. Although the support rod of this type of structure is simpler to operate than the first type, it still has problems. The following disadvantages: (1) Since the side is fixed with a clip that needs to clamp the cloth 100, the universal joint 230 connection structure is not suitable for the anti-slip top plate 300 and the telescopic rod 200, and only the above-mentioned swinging pivot structure can be used. The adjustable range of this structure is limited, which may cause the anti-slip top plate 300 to not be able to fully contact the top wall of the channel, thereby reducing the supporting performance; (2) When a part of the cloth 100 has been in contact with the top wall of the channel, but the angle of the anti-slip top plate 300 and the top wall of the channel are inconsistent, and the anti-slip top plate 300 needs to be tilted away from the clip to make them consistent, the side clip 400 will limit the swing range of the anti-slip top plate 300 relative to the telescopic rod 200. When the swing range is large, the cloth 100 is easy to slip out of the clip, and the cloth 100 may be torn. In order to minimize the occurrence of the above situation, the anti-skid top plate 300 should be adjusted before the telescopic rod 200 is lifted upward, so that the angle of the anti-skid top plate 300 is as close as possible to the angle of the top wall of the channel, and then the telescopic rod 200 is extended. However, even if it is adjusted in advance, the anti-skid top plate 300 may still swing under the pulling force of the cloth 100 during the lifting process, and the above-mentioned problems (1) and (2) will still occur.

[0048] In contrast, this embodiment provides a support head and a support rod to solve the above technical problems.

[0049] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0050] Example 1

[0051] This embodiment provides a support rod head structure 1, referring to Figure 4 and Figure 5, this embodiment provides a support rod head structure 1, which includes a connecting seat 11, a steering seat 12 and a top plate 13; a first groove 110 recessed downward is provided at the top of the connecting seat 11, and the first groove 110 penetrates the connecting seat 11 along the X direction; the steering seat 12 is rotatably installed in the first groove 110 through a Y-direction pin shaft 15, and the steering seat 12 can swing around the Y-direction pin shaft 15 to enter and exit the X-direction openings at both ends of the first groove 110 in the X direction; the steering seat 12 is made of an elastic material, and a second groove 120 is provided on its top surface, and the second groove 120 penetrates the steering seat 12 along the X direction; a protruding rotating part 14 is fixed to the bottom surface of the top plate 13, and the rotating part 14 is press-fitted into the second groove 120 in a detachable manner and rotates relative to the steering seat 12.

[0052] The specific usage method is as follows:

[0053] First, refer to Figure 6 , separate the rotating part 14 of the top plate 13 from the second groove 120 of the steering seat 12, lay the baffle 100 (plastic film or other material cloth) on the top surface of the top plate 13 and wrap it downward around the bottom surface of the top plate 13, so that part of the baffle 100 covers the rotating part 14; then, refer to Figure 7 , press the rotating part 14 of the top plate 13 into the second groove 120 of the steering seat 12 (the steering seat 12 is made of an elastic material and can elastically deform when pressed in and return to its initial state to limit the rotating part 14 of the top plate 13 inside the second groove 120). At this time, the rotating part 14 can rotate relative to the steering seat 12, and the steering seat 12 can swing around the Y-direction pin shaft 15 to enter and exit the X-direction openings at both ends of the first groove 110 on the connecting seat 11 in the X direction. Thus, the steering seat 12, the connecting seat 11 and the rotating part 14 form a head structure with the composite function of "clip + universal joint". Then stand the support rod in the passage or room, make the upper surface of the top plate 13 face the top wall (or ceiling) of the passage, and extend the support rod until a "standing upright" support structure is formed. During this process, the top plate 13 can adapt to different angles of the top wall of the passage through the above-mentioned head structure with the composite function of "clip + universal joint".

[0054] The support rod head structure 1 provided by this embodiment can be assembled with the telescopic rod 200 into a support rod (refer to Figure 8 , fix the lower end of the connecting seat 11 to the top end of the telescopic rod 200), and is used to support the baffle 100 to enclose the working area during construction. Compared with the above two types of support rods in the prior art, this embodiment has at least the following beneficial effects:

[0055] (1) The composite function of "clip + universal joint" that can be achieved by two sets of accessories in the prior art can be realized only through a set of accessories. The rotation of the universal joint is not affected by other accessories, and the adjustable angle range is wider;

[0056] (2) After fixing the baffle cloth to the head structure, there is no need to adjust the baffle angle in advance. During the operation, the top plate will automatically fit the contact surface, and the baffle cloth is not easy to slip off and will not damage the baffle cloth.

[0057] (3) Fewer accessories, simpler and more convenient operation, and lower cost.

[0058] More specifically, in an alternative technical solution of this embodiment, the above-mentioned rotating part 14 is a rotating shaft 142. There are two opposite connecting ears 141 at the bottom of the top plate 13, and the rotating shaft 142 is installed between the two connecting ears 141.

[0059] In addition, in an alternative technical solution of this embodiment, anti-slip protrusions 131 are also provided on the top surface of the top plate 13 to increase the friction between the top plate 13 and the baffle cloth 100 and prevent the baffle cloth 100 from slipping.

[0060] Embodiment Two

Refer to Figures 8 to 11 , this support rod includes a telescopic rod 200 and the support rod head structure 1 provided in any one of the alternative embodiments in Embodiment One; the lower end of the connecting seat 11 of the support rod head structure 1 is fixedly connected to the top end of the telescopic rod 200. The fixing method includes but is not limited to, an installation blind hole is provided at the lower end of the connecting seat 11, and after the top end of the telescopic rod 200 is inserted into the installation blind hole, it is fixedly connected to the connecting seat 11 through a pin.

The lower end of the connecting seat 11 is fixedly connected to the top end of the inner rod 3. The fixing method includes but is not limited to, an installation blind hole is provided at the lower end of the connecting seat 11, and after the top end of the inner rod 3 is inserted into the installation blind hole, it is fixedly connected to the connecting seat 11 through a pin. The inner rod 3 includes an integrally connected cylindrical main body 31 and an eccentric shaft rod 32; the elastic locking sleeve 4 is sleeved outside the cylindrical main body 31, the outer rod 2 is sleeved outside the elastic locking sleeve 4, and relative rotation of the eccentric shaft rod 32 and the outer rod 2 can make the eccentric shaft rod 32 push the elastic locking sleeve 4 to expand radially to lock the outer rod 2 and the cylindrical main body 31 together. The spring assembly 6 is arranged inside the outer rod 2 and includes an upper plug 61, a spring 62 and a lower plug 63; the upper plug 61 abuts against the bottom of the eccentric shaft rod 32 and is fixedly connected to the inner wall of the outer rod 2, the lower plug 63 is fixedly installed at the top end of the bottom compression rod 5, the top end of the spring 62 is fixed to the bottom of the upper plug 61, and the bottom end of the spring 62 is fixed to the top of the lower plug 63.
