Description

Technical Field

[0001] This utility model relates to the field of lightning protection device technology, and more specifically, to a support frame for lightning protection belts. Background Technology

[0002] Lightning protection strips are lightning protection devices applied to the rooftops of buildings. They are typically made of round steel and laid along the roof. Due to the height requirements of lightning protection strip installation, support frames are necessary. Existing lightning protection strip support frames have revealed two problems: First, the workload is heavy. Expansion bolts need to be installed at the bottom of the support frame, and the top clamps also require bolt connections. Installing a single support frame involves a large number of bolt tightening operations. Since many support frames are used during lightning protection strip installation, the amount of bolt tightening work for workers is enormous, resulting in high labor intensity. Second, the bottom of the support frame is exposed after installation. Because the lightning protection strip is laid openly, rainwater can enter the expansion bolt holes during rainy weather, causing the holes to crack over time and affecting the stability of the support frame. In view of these two problems, an improved design of the lightning protection strip support frame is needed, hence this project. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support frame for lightning protection tape. This utility model improves the design of the lightning protection tape clamping position structure and the bottom position structure of the support frame body. This utility model eliminates the bolt tightening operation at the lightning protection tape clamping position and also meets the sealing requirements of the bottom position of the support frame body.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A support frame for a lightning interceptor includes a support frame body, an upper clamp, and an outer cover. The support frame body includes a base and a support rod. The support rod is vertically installed on the base, and a lower clamp is connected to the top of the support rod. The upper clamp is assembled and installed on the lower clamp. The upper clamp and the lower clamp are connected by a snap-fit ​​connection, and a clamping cavity is formed between the upper clamp and the lower clamp to accommodate the passage of the lightning interceptor. The outer cover is fitted onto the outside of the base and the support rod.

[0006] Furthermore, a rod seat is connected to the center of the base, and a threaded section is provided at the bottom of the support rod. The bottom of the support rod is threaded to the rod seat, and the base has two through holes, which are symmetrically arranged.

[0007] Furthermore, the lower clamp is fixedly connected to the top of the support rod. A first half-cavity is opened in the center of the top surface of the lower clamp. Two inclined ramps are opened on both sides of the first half-cavity. The two ramps are symmetrically arranged. The upper clamp includes a clamp body. A second half-cavity is opened in the center of the bottom surface of the clamp body. Two locking feet are connected to the bottom surface of the clamp body. The two locking feet are symmetrically arranged with the second half-cavity as a reference. A hook is connected to the bottom of the locking feet.

[0008] Furthermore, the first and second half-cavities are joined together to form a clamping cavity, and the joining of the upper and lower clamping seats causes the inner side of the clamping foot to fit against the slope, and the hook at the bottom of the clamping foot hooks onto the bottom surface of the lower clamping seat.

[0009] Furthermore, the width of the ramp matches the thickness of the clamp.

[0010] Furthermore, each of the two locking feet has an upward-sloping pull ring attached to its outer side wall.

[0011] Furthermore, a groove is provided at the center of the top surface of the upper clamp.

[0012] Furthermore, the outer edge of the base protrudes upward to form a side edge, the outer wall of the side edge is provided with external threads, the inner wall of the outer cover is provided with internal threads, and the external threads and internal threads are matched.

[0013] Furthermore, a guide sleeve is connected to the top of the outer cover, and the guide sleeve is fitted onto the outside of the support rod. The top of the inner hole of the guide sleeve is provided with a first chamfer, and the bottom outer edge of the outer cover is provided with a second chamfer.

[0014] The beneficial effects of this utility model are:

[0015] This utility model improves the design of the lightning protection belt clamping position structure. The upper clamp and the lower clamp are connected by a snap-fit, which has the advantages of convenient installation and eliminating the need for tightening bolts. This utility model also improves the design of the bottom position structure of the support frame body. By adding an outer cover, the bottom of the support frame body is sealed. This design not only solves the problem of rainwater entering the expansion bolt holes, but also extends the service life of the support frame and improves the appearance of the support frame.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 The lightning protection strip support frame shown includes a support frame body 1, an upper clamp 2, and an outer cover 4. The support frame body 1 includes a base 11 and a support rod 12. The base 11 is installed on the top surface of the roof parapet using expansion bolts. The base 11 has two through holes 112, which are symmetrically arranged. The through holes 112 correspond to the threaded sections at the top of the expansion bolts. The support rod 12 is vertically installed on the base 11 and serves as a support for the clamping part. A lower clamp 13 is connected to the top of the support rod 12. The upper clamp 2 is assembled and installed on the lower clamp 13. The upper clamp 2 and the lower clamp 13 are connected by a snap-fit ​​connection, forming a cavity 3 between the upper clamp 2 and the lower clamp 13 that can accommodate the lightning protection strip. Common lightning protection strips are made of galvanized round steel, therefore... The clamping cavity 3 is a through circular hole of matching size. The round steel lightning catcher belt passes through the clamping cavity 3. The support frame supports the bottom of the lightning catcher belt to meet the requirements of the suspended installation of the lightning catcher belt. Since the upper clamp 2 and the lower clamp 13 of this utility model are connected by a snap-fit, the bolt tightening operation is saved. Given that there are a large number of support frames to be installed, the labor intensity of workers can be greatly reduced. This utility model is designed with an outer cover 4 fitted on the outside of the base 11 and the support rod 12. After the outer cover 4 is installed in place, the outer cover 4 forms a closed effect on the bottom of the support frame body 1. This can solve the problem of rainwater entering the expansion bolt holes, thereby extending the service life of the support frame. The outer cover 4 can also beautify the appearance of the support frame, making the installed lightning catcher belt system look neat.

[0023] like Figure 2As shown, a rod seat 111 is connected to the center of the base 11, and a threaded section 121 is provided at the bottom of the support rod 12. The bottom of the support rod 12 is threaded to the rod seat 111. The threaded connection of the support rod 12 is to facilitate the installation of the outer cover 4. When in use, the outer cover 4 is first put on the outside of the support rod 12, and then the support rod 12 is fixedly installed.

[0024] like Figure 2 and Figure 3 As shown, the lower clamp 13 is fixedly connected to the top of the support rod 12. A first semi-cavity 31 is formed in the center of the top surface of the lower clamp 13. Two inclined ramps 131 are formed on both sides of the first semi-cavity 31. The two ramps 131 are symmetrically arranged, as shown. Figure 4 As shown, the upper clamp 2 includes a clamp body 21. A second semi-cavity 32 is formed in the center of the bottom surface of the clamp body 21. After the upper clamp 2 and the lower clamp 13 are assembled, the first semi-cavity 31 and the second semi-cavity 32 are combined to form a complete clamping cavity 3. Two locking feet 22 are connected to the bottom surface of the clamp body 21. The two locking feet 22 are symmetrically arranged with the second semi-cavity 32 as a reference. A hook 23 is connected to the bottom of the locking feet 22. The lower clamp 13 is fixed in position. The upper clamp 2 is assembled by pressing down. When the upper clamp 2 is pressed down, the locking feet 22 slide down along the ramp 131. During the pressing down process of the upper clamp 2, the ramp 131 can cause the locking feet 22 to expand and deform outward until the hook 23 passes the bottom of the ramp 131. Then, the clamp 22 rebounds (the upper clamp 2 is made of a material with good elastic deformation, and the clamp 22 has a certain deformation capacity), and the hook 23 hooks onto the bottom surface of the lower clamp 13. At this time, the inner side of the clamp 22 fits against the slope 131. The presence of the hook 23 makes it impossible for the upper clamp 2 to be pulled up. This utility model also designs the width of the slope 131 to match the thickness of the upper clamp 2. That is to say, after the upper clamp 2 is assembled, it is positioned vertically and laterally, achieving a fixed connection. The installation method of the upper clamp 2 of this utility model does not require the use of bolts, saving a lot of bolt tightening operations. The upper clamp 2 of this utility model only needs to be pressed for installation, which has the advantage of convenient installation.

[0025] During the installation of the lightning arrester, the round steel lightning arrester is first placed on all the support frames. At this time, the upper clamp 2 and the lower clamp 13 are not assembled. Only after the installation is complete are the upper clamp 2 and the lower clamp 13 assembled one by one. This reduces rework during installation. In this operating mode, the upper clamp 2 and the lower clamp 13 are actually connected in one go, and there is no problem of repeated disassembly. To address occasional disassembly situations, such as... Figure 4 As shown, this utility model can design and connect an inclined upward-mounted pull ring 24 to the outer side wall of each of the two clamping feet 22. The worker's fingers can be inserted into the pull ring 24, and at the same time, pulling the pull ring 24 outward can form an outward expansion deformation effect of the clamping feet 22. The outward expansion deformation of the clamping feet 22 can make the hook head 23 leave the bottom surface of the lower clamping seat 13. At this time, lifting the upper clamping seat 2 can form a disassembly effect of the upper clamping seat 2.

[0026] like Figure 4 As shown, this utility model has a groove 25 in the center of the top surface of the upper clamp 2. The groove 25 is centered and can guide the worker to press the groove 25 to achieve accurate installation.

[0027] like Figure 2 and Figure 3 As shown, the outer edge of the base 11 protrudes upward to form a side 113. The outer wall of the side 113 is provided with an external thread 114, and the inner wall of the outer cover 4 is provided with an internal thread 41. The external thread 114 matches the internal thread 41. The outer cover 4 is connected to the base 11 through the meshing of the external thread 114 and the internal thread 41. The top of the outer cover 4 is connected with a guide sleeve 42, which is fitted onto the outside of the support rod 12. The guide sleeve 42 forms a closure at the outside of the support rod 12. The bottom of the outer cover 4 forms a closure at the mounting surface of the base 11 (the outer cover 4 needs to be screwed downwards so that the bottom fits against the mounting surface of the base 11). To ensure reliable sealing, the present invention provides a first chamfer 421 at the top of the inner hole of the guide sleeve 42 and a second chamfer 43 at the bottom outer edge of the outer cover 4. Both the first chamfer 421 and the second chamfer 43 can be filled with silicone sealant to ensure reliable sealing. This design solves the problem of rainwater entering in exposed environments.

[0028] When using this utility model, first fix the base 11 to the top surface of the parapet wall, then fit the outer cover 4 on the outside of the support rod 12, then thread the support rod 12 and the base 11 together, then place the round steel lightning catcher on the lower clamp 13, and after the round steel lightning catcher is laid, assemble the upper clamp 2 to fix the round steel lightning catcher, then screw the outer cover 4 to make the outer cover 4 fit on the ground, and finally apply glass glue to the first chamfer 421 and the second chamfer 43 on the outer cover 4.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
