A telescoping device on a cake turntable

Abstract

A telescopic device for a cake turntable includes an inner tube and an outer tube. The inner tube has L-shaped grooves on both its front and rear sides, a retaining ring at the bottom, and a bearing stop inside. A fixing ring is located inside the upper part of the outer tube, with keyways on both its front and rear sides. A fixing tube and a fixing cap are located at the bottom of the outer tube. The L-shaped grooves consist of straight and horizontal grooves, with the horizontal groove at the bottom of the straight groove. The inner tube is placed inside the outer tube to form a telescopic rod. Rotating the inner tube clockwise connects the keyways with the horizontal grooves, extending the telescopic rod and fixing its height. Rotating the inner tube counterclockwise connects the keyways with the straight grooves, retracting it to its original height.

Description

Technical Field

[0001] This utility model relates to an accessory, particularly suitable for a telescopic device on a cake turntable. Background Technology

[0002] With social progress, economic prosperity, and improved living standards, the sales of cake turntable products have continued to grow and are exported all over the world. Currently, the telescopic structure of cake turntables is generally composed of a combination of latches and pins, which has the problem that the pins can easily pinch fingers during use. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, this utility model provides a telescopic device for a cake turntable. In order to reduce the size, the original rotating rod is changed to a telescopic rod. In order to facilitate telescopic movement and reduce costs, the original telescopic rod with a combination of lock and ball is directly changed to a telescopic rod with an "L"-shaped buckle and key combination. In order to ensure that the telescopic rod does not detach, a fixing ring is provided on the upper part of the outer tube and a retaining ring is provided on the inner tube. It has the characteristics of simple structure, convenient operation, safety and firmness.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a telescopic device on a cake turntable, including an inner tube and an outer tube. The inner tube is provided with an "L"-shaped buckle groove on both the front and back sides, and a retaining ring is provided at the bottom. A bearing stop is provided inside the inner tube. A fixing ring is provided inside the upper part of the outer tube. The fixing ring is provided with groove keys on both the front and back sides. A fixing tube and a fixing cover are provided at the bottom of the outer tube. The "L"-shaped buckle groove is composed of a straight groove and a horizontal groove, and the horizontal groove is located at the bottom of the straight groove. The inner tube is located inside the outer tube to form a telescopic rod.

[0005] Furthermore, rotating the inner tube clockwise connects the keyway to the transverse groove, thus extending the telescopic rod and fixing its height.

[0006] Going a step further, rotate the inner tube counterclockwise, and the keyway connects with the straight groove, thus retracting it to its original height.

[0007] The slot key is located in the latching groove to serve as a positioning and extension mechanism.

[0008] The fixing ring on the outer tube contacts the retaining ring on the inner tube to prevent the inner tube from separating from the outer tube.

[0009] The beneficial effects of this utility model are as follows: In order to reduce the volume, the telescopic device on the cake turntable has changed the original rotating rod to a telescopic rod. In order to facilitate telescopic movement and reduce costs, the original telescopic rod with a combination of lock and ball has been directly changed to a telescopic rod with an "L"-shaped buckle and key combination. In order to ensure that the telescopic rod does not detach, a fixing ring is provided on the upper part of the outer tube and a retaining ring is provided on the inner tube. It has the characteristics of simple structure, convenient operation, and safe and firm. Attached Figure Description

[0017] exist Figures 1-3 In a cake turntable, a telescopic device is provided, comprising an inner tube 1 and an outer tube 2. The inner tube has an "L"-shaped groove 3 milled on both the front and back sides, a retaining ring 9 machined at the bottom, a bearing retainer machined inside the inner tube, and a fixing ring 10 machined inside the upper part of the outer tube. The fixing ring has grooves and keys 11 milled on both the front and back sides. The lower part of the outer tube is connected to a fixing tube 6 and a fixing cover 5. The "L"-shaped groove is composed of a straight groove 7 and a horizontal groove 8, and the bottom of the horizontal groove is connected to the bottom of the straight groove. The inner tube is installed inside the outer tube to form a telescopic rod 4.

[0018] Furthermore, rotate the inner tube clockwise once, and the keyway connects with the transverse groove, thus extending the telescopic rod and fixing its height.

[0019] Going a step further, rotate the inner tube counterclockwise, and the keyway connects with the straight groove, thus retracting it to its original height.

[0020] exist Figure 4 In the middle, the inner tube at the upper part of the telescopic rod 4 is connected to the bearing on the turntable 12, the fixed tube at the lower part of the outer tube of the telescopic rod is connected to the fixed plate 13, and the fixed cover is installed on the fixed plate, thus forming a cake turntable.

[0021] exist Figure 5 In the original locking pin telescopic rod 14, a locking buckle 16 and a pin 17 are installed, with a gap 15 left on the locking buckle.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of the specification, claims and drawings of this utility model, as well as direct or indirect applications of other related technical fields, are included within the patent protection scope of this utility model.
