Description

Technical Field

[0001] The utility model belongs to the technical field of communication equipment, and in particular relates to a wind and sand proof network frame structure. Background Art

[0002] In field communication operations, portable optical cables and doubled cables are often used. These cables are retracted and released using portable retractable and retractable equipment, namely a reel, which includes a reel or a reel frame. The reel frame is divided into variable speed and non-variable speed types. During the retractable and retractable process, the reel needs to be quickly disassembled and assembled from the reel frame according to actual use needs. Traditional reels use a plug-in crankshaft to disassemble and assemble the reel. Reelers with this structure, especially variable speed reelers, have a gap between the shaft and the speed change housing. When used in dusty areas, dust can enter the speed change housing and the gap between the shaft and the hole, causing the rotating mechanism to get stuck.

[0003] The application number is CN201120236999.1, and the name of the utility model is a brake-type double-wire winding car. A brake-type double-wire winding car is disclosed, including a frame, a wire rack, and a wire drum; a crank is provided on one side of the frame, and the crank drives a shaft body through a gear set. The shaft body is a half shaft and can slide along the axial direction. The other side of the frame is symmetrically provided with the half shaft, and the half shaft on this side passes through a brake box, and the brake handle of the brake box extends to the side of the frame; the surfaces of the half shafts on both sides are provided with anti-wire ring grooves and wire-receiving ring grooves for positioning, and the outer side of the half shaft is provided with a positioning column matched with the anti-wire ring groove box wire-receiving ring groove, and the outer end of the half shaft is fixedly connected to a half shaft handle, and the inner end of the half shaft is matched with the wire drum sleeve of the wire drum. The winding car can not only conveniently realize the loading, laying and retrieving of the double wire, but also effectively prevent the phenomena of shaft loss, disordered wire, dropped wire, and wire jam.

[0004] However, the above-mentioned network vehicle cannot be used in dusty areas because the space between the shaft and the transmission housing is filled with sand. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0034] like Figure 1 As shown, the utility model is a wind and sand proof net frame structure, comprising a fixed axis assembly 1, the fixed axis assembly 1 is installed on the left side of a tripod 2, a slider seat 3 is installed on the right side of the tripod 2, and a speed change assembly 4 is installed in the slider seat 3.

[0035] Among them, Figure 2 As shown, the fixed axis assembly 1 includes:

[0036] The shaft sleeve 101 is welded on the tripod 2 and is used to support the bearing 106 and the rotating shaft 102 .

[0037] The rotating shaft 102 is installed in two bearings 106. The rotating shaft 102 rotates along with the bearings 106, and the boss on the rotating shaft 102 drives the wire drum to rotate together.

[0038] The handle 103 is mounted on one end of the rotating shaft 102. It is used when installing the wire drum so that the boss on the rotating shaft 102 corresponds to the groove on the wire drum, and the rotating shaft 102 is inserted into the hole at the end of the wire drum.

[0039] Bearing retaining ring 104 is installed on the axle sleeve 101, and is a pair. The bearing retaining ring 104 on the left side is located at the left side of the left bearing, and the right side bearing retaining ring 106 is located at the right side of the right bearing.

[0040] The hanging ear 105 is installed on the shaft sleeve 101 and, together with the hanging ear on the speed change assembly 4, serves as a hook hole for the shoulder strap, which is a traditional structure.

[0041] The bearings 106 are a pair and are both mounted on the shaft sleeve 101 . Both bearings 106 are bearings 106 with rubber sealing pads.

[0042] The rotating shaft 102 and the bearing 106 are interference fit, and the rubber sealing gasket of the bearing 106 can prevent sand and dust from entering the interior of the rotating part.

[0043] like Figure 3As shown, the slider seat 3 is composed of a seat body 301 and a liner 302. The seat body 301 has a pair of parallel slide grooves, and a liner 302 (wear-resistant material) is embedded in the slide groove. The wear-resistant material has a little creep performance (such as POM, nylon, PE, brass and other materials). Grooves are evenly arranged in the liner 302 (wear-resistant material) to fit tightly with the slider of the speed change component 4. When the size of the slider of the speed change component 4 is slightly larger than the inner size of the liner 302 (wear-resistant material), since the liner 302 (wear-resistant material) has a groove, its protruding part can be deformed and at the same time, it is in close contact with the slider of the speed change component 4. Due to the effect of the groove, the liner 302 (wear-resistant material) will not lock the slider and can slide freely in the slider seat 3, but impurities such as sand and dust cannot enter the sliding mating surface. A small hole is set at the bottom of each end of the slideway of the slider seat 3 to facilitate the fall out of impurities such as dust (such as Figure 7 The two end faces of the slide groove are end face baffles 303, which are used to block the speed change assembly 4 to prevent the slider of the speed change assembly 4 from sliding out (as shown in FIG. Figure 7 As shown), one side of the slide groove has a threaded hole 304.

[0044] like Figure 4-Figure 6 As shown, the matching method of the gears in the speed change assembly is the same as that of Patent No. ZL202221158646.9.

[0045] The speed change assembly 4 includes: a speed change box cover 401, a final gear shaft mounting bearing 402, a final gear shaft 403, an intermediate bearing 404, a primary gear 405, a primary gear mounting bearing 406, a speed change box rear housing 407, a crank assembly 408, a secondary gear mounting bearing 409, and a secondary gear 410.

[0046] The transmission case cover 401 is connected to the transmission case rear housing 407 by bolts, the final gear shaft mounting bearing 402 is mounted on the transmission case cover 401, the primary gear mounting bearing 406 is mounted on the transmission case rear housing 407, the right end of the primary gear 405 is mounted on the primary gear mounting bearing 406, the intermediate bearing 404 is mounted on the primary gear 405, one end of the final gear shaft 403 is mounted on the final gear shaft mounting bearing 402, and the other end of the final gear shaft 403 is mounted on the intermediate bearing 404. The secondary gear mounting bearing 409 is a pair, the left one is mounted on the transmission case cover 401, and the right one is mounted on the transmission case rear housing 407. One end of the secondary gear 4010 is fixed on the secondary gear mounting bearing 409 on the left, and the other end is fixed on the secondary gear mounting bearing 409 on the right. The primary gear 405 is meshed with the secondary gear 4010, and one end of the crank assembly 408 is fixedly connected to the primary gear 405.

[0047] like Figure 6As shown, in addition, the bottom of the rear housing 407 of the transmission case has two parallel sliders, and the sliders have holes. When the sliders are matched with the slide slots, screws are passed through the holes and the threaded holes 304 on the sides of the slide slots to fix the transmission assembly 4 on the slider seat 3.

[0048] The working process of this utility model:

[0049] The tripod 2 adopts the traditional winding machine support structure, and the left fixed axis component 1 is welded to the tripod 2. A rubber sealed bearing is installed at each end of the fixed axis component 1, which is limited by a retaining spring. A rotating shaft 102 is installed in the inner hole of the bearing. The rotating shaft 102 has a boss for driving the wire drum to rotate like the traditional winding machine rotating shaft. The rotating shaft 102 and the bearing 106 have an interference fit. A circular handle 103 is set at the tail end of the rotating shaft 102, which is convenient for manual rotation and alignment with the wire drum hole when installing the wire drum. A slider seat 3 is installed on the right side of the tripod 2, and a speed change component 4 is installed in the slider seat 3. The bottom of the speed change component 4 has two parallel sliders. After being installed in the slider seat 3, it can slide left and right in the slider seat 3, and is locked and limited by the locking screw on the slider seat 3.

[0050] The slider at the bottom of the speed change assembly 4 is installed into the slider seat 3. When the speed change assembly 4 is pushed to the left to the bottom, it is the working position. At this time, the screw is tightened into the threaded hole of the slider, and the speed change assembly 4 is fixed. At this time, the wire reeling and unwinding operation can be performed. When the wire reel needs to be removed from the winding vehicle frame, the screw is unlocked and the speed change assembly 4 is slid to the right to remove the wire reel.

[0051] like Figure 8 As shown, the travel length of the speed change assembly in the slider seat is C, which is greater than the sum of the length A of the rotating shaft 102 on the right side of the sleeve 101 and the length B of the intermediate bearing on the left side of the speed change box cover 101.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
