Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a telescopic clamp. Background Technology

[0002] Currently, common commercial hair perming equipment typically uses several pull boxes and dedicated lever-type spring clips to fix and suspend curling irons of different sizes. Since the outer wall of the curling iron needs to be wrapped around the hair, the lever-type spring clips usually clamp both ends of the curling iron along its length. Therefore, the opening of this type of lever-type spring clip has a large opening when reset. Each time the curling iron is fixed, it is not necessary to use a lot of force to press the lever-type spring clip to match the opening of the curling iron. However, the opening of the lever-type spring clip with this structure has a low adjustable range, and a certain size of lever-type spring clip can match a limited number of curling iron sizes. As a result, a large number of lever-type spring clips of different sizes need to be equipped for the hair perming equipment, and the lever-type spring clips need to be frequently replaced from the pull box, which affects the convenience of hairstylists during the hair perming process. Utility Model Content

[0003] To address the technical deficiencies in the background art, this utility model proposes a telescopic clip, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0004] A telescopic clamp includes an outer shell, a clamping mechanism, and a compression spring. The outer shell is hollow and forms a movable cavity. The clamping mechanism is located inside the movable cavity. Telescopic holes are passed through the opposite sides of the outer shell.

[0005] The clamping mechanism includes the following structure: a movable slider, which has two movable sliders, each of which has a clamping rod extending toward the other movable slider. The ends of the two clamping rods extend from two telescopic holes to the outer shell and are provided with clamping feet. A clamping space is formed between the two clamping feet.

[0006] The two ends of the compression spring abut against the surfaces of the two movable sliders, respectively.

[0007] As a further technical solution of this utility model, the clamping rod and the clamping foot are perpendicular to each other, and each of the clamping feet is provided with a clamping hook extending toward the other clamping foot.

[0008] As a further technical solution of this utility model, the outer shell is provided with two telescopic grooves on one side, which are respectively matched with two movable sliders, and the movable slider is provided with a hand pressure plate extending from the telescopic grooves to the outer shell.

[0009] As a further technical solution of this utility model, a connecting rod matching the telescopic slide is provided between the movable slider and the hand pressure plate, and the connecting rod extends from one side of the movable slider toward the other movable slider.

[0010] As a further technical solution of this utility model, one of the clamping rods is provided with a movable slide rail extending along the top of the clamping rod, and the other clamping rod is provided with a movable slide groove matching the movable slide rail at the bottom.

[0011] As a further technical solution of this utility model, a compression spring block is provided on one side of the inner wall of the outer shell, and the compression spring block is located in the center of the movable cavity.

[0012] As a further technical solution of this utility model, a fixing ring is provided on the top of the outer side of the outer shell.

[0013] The beneficial effects of this utility model are as follows:

[0014] The telescopic clamp of this invention adjusts the opening of the clamping space by pushing two movable sliders to move towards each other, causing the two clamping feet to move in opposite directions. This makes it easier for the clamped item to enter the clamping space. Then, the elasticity released by the compression spring pushes the two clamping feet to move relative to each other and clamp the item in the clamping space. Since both clamping feet move in a straight line during the adjustment of the clamping space opening, the adjustable opening range of the clamping space is large, allowing the telescopic clamp to clamp more items of different sizes.

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A telescopic clamp includes an outer shell 1, a clamping mechanism 2, and a compression spring 3. The outer shell 1 is hollow and forms a movable cavity. The clamping mechanism 2 is located inside the movable cavity. Telescopic holes 11 are passed through both opposite sides of the outer shell 1. The clamping mechanism 2 includes the following structure: movable sliders 21, two movable sliders 21 are provided, each movable slider 21 is provided with a clamping rod 22 extending toward the other movable slider 21, the ends of the two clamping rods 22 extend from the two telescopic holes 11 to the outside of the outer shell 1 and are provided with clamping feet 23, and a clamping space is formed between the two clamping feet 23; the two ends of the compression spring 3 abut against the surfaces of the two movable sliders 21 respectively.

[0023] This utility model is mainly used to clamp and fix the curling iron in the hair perming equipment. The outer top of the outer shell 1 is provided with a fixing ring 14. The fixing ring 14 is used to cooperate with the telescopic cable of the pull box to fix it on a hanging bracket. The telescopic clamp can adjust the hanging height more flexibly through the pull box. When performing the hair perming operation, the two ends of the curling iron with hair already wrapped on the surface are clamped by the telescopic clamp, and then the curling iron can be suspended by the telescopic clamp and the pull box to avoid the curling iron from contacting the scalp.

[0024] The principle of this utility model's telescopic clip for holding curling irons is as follows: Since the two ends of the compression spring 3 abut against the surfaces of the two movable sliders 21 respectively, in the reset state, the distance between the two movable sliders 21 reaches its maximum value under the elastic force of the compression spring 3. The two movable sliders 21 are located at opposite ends within the movable cavity. Because the clamping rod 22 on one side of the movable slider 21 extends towards the other movable slider 21, and the end of the clamping rod 22 is provided with a clamping foot 23, the distance between the two clamping feet 23, i.e., the length of the clamping space, is a fixed value. At this time, the length of the clamping space is at its minimum value. When the two movable sliders 21 are pushed... When the two clamping feet move in opposite directions, the compression spring 3 will be squeezed and the two clamping feet 23 will move in opposite directions, thus increasing the length of the clamping space. At this time, the curling iron is placed in the clamping space, and then the external force applied to the movable slider 21 is released, causing the compression spring 3 to release its elastic potential energy and push the two movable sliders 21 to move in opposite directions. At the same time, the two clamping feet 23 will move relative to each other, reducing the length of the clamping space until the two clamping feet 23 respectively abut against the two ends of the curling iron in the length direction. The two clamping feet 23 will clamp the curling iron under the action of the compression spring 3, thereby enabling the telescopic clamp to clamp and fix the curling iron.

[0025] Based on the principle of the telescopic clip for holding the curling iron, the telescopic clip adjusts the distance between the two clamping feet 23 by the relative movement of two movable sliders 21 and the compression spring 3, thus adjusting the clamping space opening. The two clamping feet 23 are located at opposite ends on the outer side of the outer shell 1, meaning the initial opening of the clamping space is close to the length of the outer shell 1. During the adjustment of the clamping space opening, both the movable sliders 21 and the clamping feet 23 move in a straight line, and the movable sliders 21 can move from the end of the outer shell 1 to a position close to the center of the outer shell 1. The maximum total distance that the two movable sliders 21 can move is approximately 60% to 80% of the length of the outer shell 1. Since the clamping feet 23 and the movable sliders 21 move synchronously, they can achieve the same movement distance. If the initial opening of the clamping space is set to be close to the length of the outer shell 1, the distance between the two clamping feet 23 and the outer shell 1 can be adjusted. Since the length of body 1 is the same, the opening range of the clamping space is 100%~180% of the length of body 1, usually 100%~170% of the length of body 1. That is, the opening of the clamping space can be adjusted by 1.7 times. In addition, since the clamps for holding curling irons usually need to be set with an initial opening, the opening of commonly used lever-type spring clamps can usually only be adjusted by about 1.3 times. It can be seen that the clamping space in the telescopic clamp of this utility model can be adjusted over a wide range, so that more curling irons of different sizes can be clamped and fixed. Usually, only one or two different sizes of telescopic clamps are needed to match most curling irons of different lengths. When hairdressers perform perming operations, they do not need to equip multiple sizes of clamps for different sizes of curling irons, thus improving the convenience of the perming operation.

[0026] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The clamping rod 22 and the clamping foot 23 are perpendicular to each other. Each clamping foot 23 is provided with a clamping hook 24 extending toward the other clamping foot 23. The two ends of the curling iron in the length direction are usually provided with inwardly recessed grooves. When the curling iron is clamped and fixed by the telescopic clamp, the two clamping hooks 24 can be respectively inserted into the grooves at both ends of the curling iron, thereby hooking the curling iron by the clamping hooks 24, improving the firmness of the telescopic clamp on the curling iron, and thus preventing the curling iron from falling off during the perming process.

[0027] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 3 The outer casing 1 has two telescopic grooves 12 on one side, which are respectively matched with two movable sliders 21. The movable sliders 21 have hand pressure plates 25 extending from the telescopic grooves 12 to the outside of the outer casing 1 on one side. The hand pressure plates 25 can serve as force-bearing structures to push the movable sliders 21 to move. When adjusting the clamping space opening of the telescopic clip and clamping the curling iron with the telescopic clip, the user can apply relative force to the two hand pressure plates 25 with two fingers, so that the two movable sliders 21 move towards each other, thereby increasing the clamping space opening of the telescopic clip, making it easier to clamp the curling iron and better match curling irons of different lengths. In addition, the telescopic grooves 12 serve as channels for the movement of the hand pressure plates 25, allowing the hand pressure plates 25 to move linearly along the outside of the outer casing 1.

[0028] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A connecting rod 26 matching the telescopic slide 12 is provided between the movable slider 21 and the hand pressure plate 25. The cooperation between the telescopic slide 12 and the connecting rod 26 can prevent the movable slider 21 and the hand pressure plate 25 from swinging during movement, thereby improving the stability of the telescopic clip in holding the curling iron. In addition, the connecting rod 26 extends from one side of the movable slider 21 toward the other movable slider 21. With this structure, in the reset state, the distance between the two hand pressure plates 25 will be less than or equal to the distance between the two movable sliders 21. This can reduce the distance between the two hand pressure plates 25, so that two fingers of the same hand can apply force to the two hand pressure plates 25 respectively, making it convenient for the user to operate the telescopic clip with one hand.

[0029] As one of the preferred embodiments of this utility model, refer to Figure 4 , Figure 5One clamping rod 22 has a movable slide rail 27 extending along its top, and the other clamping rod 22 has a movable groove 28 matching the movable slide rail 27 at its bottom. When the movable slider 21 is pushed by an external force, the two clamping rods 22 move synchronously. One clamping rod 22 is fitted onto the surface of the movable slide rail 27 of the other clamping rod 22 through the movable groove 28, so that the two clamping rods 22 move linearly along the movable groove 28 and the movable slide rail 27. The movable slide rail 27 and the movable groove 28 are nested together to prevent the clamping rods 22 from swinging during movement, thereby improving the stability of the telescopic clamp in the process of clamping and fixing the curling iron. In addition, the side walls of the movable slide rail 27 and the movable groove 28 can serve as reinforcing ribs on the surface of the clamping rods 22, which helps to increase the strength of the clamping rods 22 and prevent their deformation.

[0030] As one of the preferred embodiments of this utility model, refer to Figure 3 A compression spring block 13 is provided on one side of the inner wall of the outer shell 1. The compression spring block 13 is located in the center of the movable cavity. The compression spring block 13 can restrict the center of the compression spring 3. During the process of the two movable sliders 21 moving towards each other and squeezing the compression spring 3, the two ends of the compression spring 3 can be squeezed towards the center more evenly, avoiding the compression spring 3 being squeezed to be biased towards one of the movable sliders 21.

[0031] In summary, the telescopic clamp of this invention adjusts the opening of the clamping space by pushing two movable sliders 21 to move towards each other, causing the two clamping feet 23 to move in opposite directions. This makes it easier for the clamped item to enter the clamping space. Then, the elasticity released by the compression spring 3 pushes the two clamping feet 23 to move relative to each other and clamp the item in the clamping space. Since both clamping feet 23 move in a straight line during the adjustment of the clamping space opening, the adjustable opening range of the clamping space is large, allowing the telescopic clamp to clamp more items of different sizes.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
