Technical Field

[0001] The utility model belongs to the technical field of air duct installation, and in particular relates to an assembly anchoring structure in a narrow space. Background Art

[0002] Ducts are pipe systems used for air delivery and distribution. There are two types: composite ducts and inorganic ducts. Composite ducts are represented by Durkduct ducts, which can be classified according to cross-sectional shape and material. The production of stainless steel ducts is to apply sealant (such as neutral glass glue) to the seams such as the bite seams, rivet seams, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, ducts can be divided into circular ducts, rectangular ducts, oblate ducts, etc. Among them, circular ducts have the smallest resistance but the largest height dimension, and are complex to produce, so rectangular ducts are mainly used. According to the material, ducts can be divided into metal ducts, composite ducts, and polymer ducts.

[0003] The volume of the air duct is large. During installation, if the spacing between adjacent air ducts is small, it is not easy to perform anchoring operations in the narrow space between adjacent air ducts. Therefore, there is an urgent need for a narrow space assembly anchoring structure that can perform anchoring operations in the narrow space between adjacent air ducts. Utility Model Content

[0004] The utility model aims to provide an assembled anchoring structure in a narrow space to solve the above-mentioned problem and achieve the purpose of being able to perform anchoring operations in a narrow space between adjacent air ducts.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-4 As shown, the utility model provides an assembly anchoring structure for a narrow space, comprising: a housing 1, a slide cylinder 2 is slidably connected to the inner side of the housing 1 along the length direction, a first slide cylinder fixing plate 201 is fixedly connected to the outer side of the lower part of the slide cylinder 2, a return spring 3 is sleeved on the outer side of the slide cylinder 2, the bottom end of the return spring 3 is fixedly connected to the top surface of the first slide cylinder fixing plate 201, the top end of the return spring 3 is fixedly connected to the inner side of the housing 1, a transmission rod 4 is slidably connected to the inner side of the slide cylinder 2, and the top end of the transmission rod 4 is transmission-connected to a screwdriver;

[0028] A mounting sleeve 5 is movably passed through the bottom inner end of the shell 1, and the mounting sleeve 5 is detachably connected to the bottom end of the shell 1. The top end of the mounting sleeve 5 abuts against the bottom end of the slide cylinder 2. A locking screw 6 is threadedly connected to the inner side of the mounting sleeve 5, and the top end of the locking screw 6 is drivingly connected to the bottom end of the transmission rod 4.

[0029] When the device is in use, first manually pull up the slide 2, install the mounting sleeve 5 at the bottom of the shell 1, and place a locking screw 6 in the mounting sleeve 5. A small part of the bottom of the locking screw 6 enters the mounting sleeve 5 to achieve positioning, and then release the slide 2, so that the bottom of the slide 2 abuts against the mounting sleeve 5, and the locking screw 6 enters the inner side of the slide 2. After that, the shell 1 is inverted and the mounting sleeve 5 is upward, and the drill hole is found in the narrow space between the air ducts. When the mounting sleeve 5 is aligned with the drill hole, the slide 2 moves upward to push the mounting sleeve 5 inward. At this time, the end of the slide 2 outside the narrow space is hammered again, so that the mounting sleeve 5 can completely enter the drill hole. Finally, the transmission rod 4 is driven to rotate by a screwdriver, thereby driving the locking screw 6 to penetrate into the mounting sleeve 5 to achieve good fixation, and then the shell 1 is pulled out with force, leaving the mounting sleeve 5 at the drill hole.

[0030] By providing the transmission rod 4, the locking screw 6 inside can be tightened outside a narrow space, which is convenient for workers to work. By providing the mounting sleeve 5 pushed by the slide cylinder 2 and detachable from the housing 1, workers can align the drilling hole conveniently and quickly, ensuring work efficiency.

[0031] A further optimized solution is that the installation sleeve 5 includes an expansion sleeve 502, which moves through the bottom end of the shell 1. The top of the expansion sleeve 502 is fixedly connected to a rubber sheet 501, and the rubber sheet 501 is located on the inner side of the bottom end of the shell 1. A plurality of equally spaced latches 503 are provided on the outer side of the middle part of the expansion sleeve 502. The expansion sleeve 502 is provided with a plurality of slots 504 along the circumferential direction, and the slots 504 are arranged along the length direction of the expansion sleeve 502.

[0032] In a further optimized solution, a plurality of protrusions are provided at equal intervals around the rubber sheet 501, and the protrusions are located on the inner side of the bottom end of the housing 1. By providing the protrusions, the position of the rubber sheet 501 can be better limited, so that the position of the protrusions that limit the rubber sheet 501 will not be pushed out of the bottom end of the housing 1 by the slide 2. In addition, the provision of the protrusions is also conducive to workers pulling out the housing 1 after anchoring.

[0033] Further optimizing the scheme, a conical head 505 is provided at the bottom end of the expansion nail sleeve 502. The setting of the conical head 505 can better find the drill hole and probe into it.

[0034] In a further optimized solution, a handle 101 is fixedly connected to the top of the housing 1. The setting of the handle 101 can better allow workers to operate the device.

[0035] In a further optimized solution, auxiliary balancing plates 102 are fixedly connected to both sides of the bottom of the housing 1. The setting of the auxiliary balancing plates 102 can better achieve auxiliary balancing and ensure that the housing 1 is perpendicular to the plane where the roof is located.

[0036] In a further optimized solution, a second slide fixing plate 202 is fixedly connected to the outer side of the top of the slide 2. The second slide fixing plate 202 is arranged to facilitate hammering the slide 2 with a small hammer, providing a force bearing surface for hammering, and by hammering the second slide fixing plate 202, the slide 2 can push the nail sleeve 502 completely into the drill hole.

[0037] Further optimization scheme, the bottom end of the transmission rod 4 is provided with a cross protrusion, and the top end of the locking screw 6 is provided with a screw cross groove, and the cross protrusion matches the screw cross groove. The cross connection method can provide a good transmission effect between the transmission rod 4 and the locking screw 6.
