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] Embodiment 1: As the specification sheet Figure 1-4 As shown, the utility model provides:

[0027] A garage ground embedded expansion hook, comprising:

[0028] An embedded tube 1, wherein a threaded rod 3 is slidably connected to the inner wall of the embedded tube 1, and a connecting hook 2 is detachably connected to the upper end of the threaded rod 3;

[0029] A dustproof component 4 is provided in the embedded tube 1 to prevent dust and stones from entering the embedded tube 1 and affecting the installation of the threaded rod 3;

[0030] The mounting mechanism 5 is used to mount the connecting hook 2 and the threaded rod 3 in the embedded tube 1 . The mounting mechanism 5 is arranged on one side of the embedded tube 1 .

[0031] As a preferred technical solution, Figure 2 and Figure 3 As shown, the installation mechanism 5 includes an expansion connection assembly 501 and a steerable pin connection assembly 502;

[0032] The expansion connection assembly 501 is arranged inside the embedded tube 1;

[0033] The steerable pin connection assembly 502 is arranged on the upper side of the threaded rod 3 .

[0034] When installing through this device, first the embedded tube 1 is fixedly installed through embedding. At this time, the dustproof component 4 collects the stone debris in the process of embedding. When the connecting hook 2 and the threaded rod 3 need to be installed, the dustproof component 4 is removed to take away the dust and debris inside. Then the expansion connection component 501 installs the threaded rod 3 in the embedded tube 1, and then the connecting hook 2 is installed through the steerable pin connection component 502. When the connecting hook 2 is installed through the steerable pin connection component 502, it has multiple installation directions, which is convenient for the subsequent installation of other equipment through the connecting hook 2. After installation, if the connecting hook 2 is not in the right direction, it can be quickly removed and reinstalled. The surface of the threaded rod 3 has a hexagonal block that can be conveniently clamped by a workpiece such as a wrench. The threaded rod 3 is rotated to tighten the connection of the expansion connection component 501.

[0035] Example 2: Figure 2 and Figure 4As shown, the expansion connection assembly 501 includes a rotating seat 5014 rotatably connected to the circumferential surface of the threaded rod 3, the circumferential surface of the threaded rod 3 is threadedly connected with an internal thread block 5011, the adjacent ends of the internal thread block 5011 and the rotating seat 5014 are fixedly connected with a deformable push piece 5012, and two fitting pieces 5013 are arranged at the lower side of the internal thread block 5011, the two deformable push pieces 5012 on the upper side are fixedly connected with the two deformable push pieces 5012 on the lower side through the two fitting pieces 5013, and the deformable push pieces 5012 are connected with the fitting pieces 5013 to form an outwardly expanded arc shape;

[0036] When the threaded rod 3 is installed, the threaded rod 3 can be inserted into the embedded tube 1. At this time, the dustproof component 4 enters the embedded tube 1. By rotating the threaded rod 3, the threaded rod 3 drives the internal thread block 5011 to descend through the thread, and the deformed push piece 5012 and the fitting piece 5013 are squeezed. The fitting piece 5013 is pushed to fit and squeeze the inner wall of the embedded tube 1 through an arc angle to fix it. At this time, the threaded rod 3 is fixed and cannot be pulled out.

[0037] As a preferred embodiment, Figure 2 As shown, the surface of the bonding sheet 5013 and the inner wall of the embedded tube 1 are both engraved with friction lines 5015, and the surface of the bonding sheet 5013 is in an arc shape that fits with the circumferential inner wall of the embedded tube 1;

[0038] The arc shape of the fitting sheet 5013 can increase the contact and extrusion area with the embedded tube 1 , and at this time, the friction pattern 5015 is tightly embedded and engaged, thereby increasing the fixing effect of the threaded rod 3 .

[0039] As a preferred embodiment, Figure 2 As shown, the lower inner wall of the embedded tube 1 is fixedly connected with a positioning seat 5016, and the positioning seat 5016 contacts and fits the surface of the rotating seat 5014;

[0040] The positioning seat 5016 can block the rotation of the rotating seat 5014, so that when the threaded rod 3 is rotated, the rotating seat 5014 will not rotate synchronously, thereby preventing the synchronous rotation of the internal thread block 5011 from affecting the squeezing effect on the deformed push piece 5012 and the bonding piece 5013.

[0041] Example 3: Figure 3 and Figure 4 The steerable pin-connection assembly 502 comprises a connecting pin 5022 and a pin-connection plug 5021 fixedly connected to the upper end of the threaded rod 3, a pin-connection socket 5023 fixedly connected to the lower end of the connecting hook 2, the pin-connection socket 5023 is slidably connected to the circumferential surface of the pin-connection plug 5021, and the pin-connection plug 5021 and the pin-connection socket 5023 are detachably connected through the connecting pin 5022;

[0042] When it is necessary to connect and fix the connecting hook 2 and the threaded rod 3, the connecting hook 2 can be moved to the upper side of the threaded rod 3. At this time, the connecting hook 2 is pressed down to insert the pin-connecting plug 5021 into the pin-connecting socket 5023. At this time, the pin-connecting socket 5023 and the pin-connecting plug 5021 are connected through the connecting pin 5022 to complete the fixation.

[0043] As a preferred embodiment, the upper end of the pin-connecting plug 5021 and the inner wall of the pin-connecting socket 5023 are both square, and the pin-connecting plug 5021 has two pin holes that are perpendicular to each other and form a "cross" shape, so that the connecting hook 2 can have multiple installation directions on the surface of the threaded rod 3, which can facilitate the subsequent installation and fixation of other equipment. At the same time, if the connecting hook 2 is not in the right direction, it can be quickly removed and reinstalled.

[0044] Example 4: Figure 2 As shown, the dust-proof component 4 includes a disposable ash storage bag 401 arranged on the inner wall of the embedded tube 1, and two drawstrings 402 are fixedly connected to the upper end of the disposable ash storage bag 401. When the embedded tube 1 is embedded or other operations are performed, dust and debris can easily enter the embedded tube 1 and affect the subsequent insertion and installation of the threaded rod 3. When the threaded rod 3 needs to be installed, the drawstring 402 can be pulled to lift the disposable ash storage bag 401. At this time, the disposable ash storage bag 401 brings out the dust and debris, and the threaded rod 3 will not be affected by the dust and debris when inserted. Blocking, two blocking grooves 404 are provided at the upper end of the embedded tube 1, and blocking blocks 403 are fixedly connected to the upper ends of the two pull straps 402. The two pull straps 402 are respectively slidably connected to the inner walls of the two blocking grooves 404. When in use, the pull strap 402 is easy to fall into the embedded tube 1, and the blocking block 403 prevents the blocking groove 404 from retreating, so that the pull strap 402 is not easy to fall into the embedded tube 1, which is convenient to use. The disposable ash storage bag 401, the pull strap 402 and the blocking block 403 are made of thin plastic skin as an integral part, and the cost is relatively low.

[0045] When the garage ground embedded expansion hook of the utility model is used:

[0046] When installing through the present device, firstly, the embedded tube 1 is fixedly installed by embedding. At this time, the disposable ash storage bag 401 collects the stone debris that falls into the embedded tube 1 during the installation process. When the connecting hook 2 and the threaded rod 3 need to be installed, the pull belt 402 is pulled to lift up and take out the dust and gravel. After the disposable ash storage bag 401 is taken out, the threaded rod 3 is inserted into the embedded tube 1, and the threaded rod 3 is rotated. Then, the threaded rod 3 drives the internal thread block 5011 to descend through the thread, and the deformed push piece 5012 and the fitting piece 5013 are squeezed. The fitting piece 5013 is pushed to fit and squeeze the inner wall of the embedded tube 1 through the arc angle, and the friction pattern 5013 between the fitting piece 5013 and the inner wall of the embedded tube 1 is formed. 15, they are embedded in each other and fixed. At this time, the threaded rod 3 is fixed and cannot be pulled out. When it is necessary to connect and fix the connecting hook 2 and the threaded rod 3, the connecting hook 2 can be moved to the upper side of the threaded rod 3. At this time, the connecting hook 2 is pressed down to insert the pin plug 5021 into the pin socket 5023. At this time, the pin socket 5023 and the pin plug 5021 are connected by the connecting pin 5022 to complete the fixation. Because the surface of the pin plug 5021 and the inner wall of the pin socket 5023 are both square, they can be installed in different directions with the same fit and are not easy to shake, which can facilitate the subsequent installation and fixation of other equipment. At the same time, if the connecting hook 2 is not in the right direction, it can be quickly removed and reinstalled.

[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
