Description

Technical Field

[0001] The utility model relates to the technical field of spring brackets, in particular to a telescopic spring bracket. Background Art

[0002] In many industrial and daily life scenarios, there is often a need for a device that can adjust its length according to actual needs and provide elastic support. For example, in furniture manufacturing, in order to adapt to the storage of items of different sizes or the requirements of human comfort, a support structure with adjustable height is needed; in mechanical equipment, in order to buffer vibrations, absorb energy or adapt to different working strokes, components with telescopic functions and elasticity are also required. Traditional fixed-length support frames or spring devices often cannot meet these diverse needs, and the installation and disassembly processes of traditional spring brackets are usually relatively complex, requiring a lot of time and effort. During installation, it may be necessary to fix the spring bracket to other components through multiple bolts, nuts and other connectors, which not only requires precise alignment and tightening operations, but also increases the operation difficulty in the case of limited space. The disassembly also faces similar problems, and due to long-term use, the connectors may rust, deform, etc., resulting in more difficult disassembly, and even may damage the spring bracket or other related components. This difficult installation and disassembly process not only increases the maintenance cost and downtime of the equipment, but also has high skill requirements for operators, restricting the use range and convenience of the spring bracket; therefore, we propose a telescopic spring bracket to solve this problem. Content of the Utility Model

[0003] The purpose of the utility model is to provide a telescopic spring bracket to solve the problems raised in the above background art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A telescopic spring bracket, comprising: a base, an installation seat is arranged inside the base, an outer sleeve is fixedly installed on the top of the installation seat, an inner sleeve is arranged inside the outer sleeve, a circular plate is slidably abutted inside the inner sleeve, a connecting rod is arranged on the top of the inner sleeve, a support frame is fixedly installed on the top of the connecting rod, a telescopic spring and a damper are arranged inside the inner sleeve, placing grooves are respectively opened inside both sides of the installation seat, and installation components are arranged inside both groups of placing grooves. The installation component comprises: a sliding frame, a sliding plate is slidably installed inside the sliding frame, a sliding rod and a plug are respectively fixedly installed at both ends of the sliding plate, the plug is movably inserted inside the installation seat, a plug board is fixedly installed on one side of the sliding frame, and the plug board is movably inserted inside the installation seat.

[0006] Preferably, the two sliding frames are respectively slidably installed inside the corresponding placement grooves. Inside both of the two sliding frames, there is a first spring. Two ends of the two first springs are respectively fixedly connected to the corresponding sliding plate and one inner wall of the sliding frame.

[0007] Preferably, there are two second springs inside the placement grooves. Two ends of the two second springs are respectively fixedly connected to the corresponding sliding frame and one inner wall of the placement groove.

[0008] Preferably, the telescopic spring is sleeved outside the damper. Two ends of the telescopic spring and the damper are respectively fixedly connected to the bottom inner wall of the circular plate and the outer sleeve. The connecting rod slidably penetrates into the inner sleeve, and one end of the connecting rod is fixedly connected to the circular plate.

[0009] Preferably, there is an internal thread on the inner wall of the outer sleeve, and an external thread is provided on the outside of the inner sleeve. The inner sleeve is threadedly connected to the outer sleeve.

[0010] Preferably, chutes are opened at the tops of the two placement grooves. The two sliding rods slidably penetrate to the tops of the sliding frames. At the tops of the two sliding rods, pulling plates are fixedly installed. The two pulling plates are respectively slidably installed inside the corresponding chutes. At the tops of the two pulling plates, handles are fixedly installed.

[0011] In the present utility model, for the retractable spring rack, by providing the inner sleeve, the outer sleeve, the connecting rod, the support frame, the telescopic spring and the damper, by rotating the inner sleeve, it gradually retracts inside the outer sleeve. The movement of the inner sleeve compresses the telescopic spring. The telescopic spring stores elastic potential energy, and at the same time, the overall length of the telescopic spring decreases. During this process, the compression force of the telescopic spring gradually increases, providing a reverse acting force for the inner sleeve to maintain a relatively stable connection with the outer sleeve. The lengths of the telescopic spring and the support frame can be adjusted, which can buffer vibrations, absorb energy or adapt to different working strokes, and can prevent the spring rack from accidentally elongating or shortening during operation, avoiding the balance of the equipment from being broken and ensuring the normal operation of the equipment, ensuring the stability and reliability of the equipment during operation. Only by rotating the inner sleeve can the length be adjusted, without the need for complex tools or professional skills, and ordinary users can easily complete the operation, saving time and labor costs. And only by rotating the inner sleeve and taking it out of the outer sleeve, the internal telescopic spring and other parts can be conveniently overhauled, maintained and replaced;

[0012] In the present utility model, for the described retractable spring rack, by providing an installation component, when horizontally pulling upwards on two handles, the two handles drive the corresponding pull plates and sliding rods to move upwards, such that the two sliding plates drive the corresponding insertion blocks to disengage from the interior of the mounting base while driving compression spring one. At this time, by horizontally pulling the two handles left and right, the two sliding frames drive the insertion plates on one side to move while compressing spring two. Under the reset action of spring one and spring two, the insertion plates are reinserted into the interior of the base, and the insertion blocks are reinserted into the interior of the mounting base. This mechanism is simple and easy to operate, allowing the operator to quickly complete the installation or disassembly work, improving work efficiency. Whether during the initial installation stage of the equipment or subsequent maintenance and replacement processes, it can bring great convenience to the user. Moreover, through the cooperation of the insertion blocks and the mounting base and the two locking methods of the cooperation between the insertion plates and the base, a dual locking mechanism is formed, which can effectively prevent the spring rack from loosening or displacing when subjected to external forces (such as vibration, impact, etc.), ensuring that the spring rack can always remain in the correct installation position and providing a reliable guarantee for its normal operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1-3, A telescopic spring frame, comprising: a base 1, an installation seat 2 is arranged inside the base 1, a jacket cylinder 3 is fixedly installed on the top of the installation seat 2, an inner cylinder 4 is arranged inside the jacket cylinder 3, a circular plate 12 is slidably abutted inside the inner cylinder 4, a connecting rod 7 is arranged on the top of the inner cylinder 4, a support frame 8 is fixedly installed on the top of the connecting rod 7, a telescopic spring 5 and a damper 6 are arranged inside the inner cylinder 4, placing grooves are respectively formed in the two sides of the installation seat 2, and installation components 9 are arranged inside the two placing grooves. The installation component 9 comprises: a sliding frame 904, a sliding plate 905 is slidably installed inside the sliding frame 904, a sliding rod 903 and a plug 906 are respectively fixedly installed at both ends of the sliding plate 905, the plug 906 is movably inserted into the installation seat 2, a plug board 908 is fixedly installed on one side of the sliding frame 904, and the plug board 908 is movably inserted into the installation seat 2.

[0019] In this embodiment, the two sliding frames 904 are respectively slidably installed inside the corresponding placing grooves. Springs 907 are arranged inside the two sliding frames 904. Both ends of the two springs 907 are fixedly connected to the corresponding sliding plate 905 and one inner wall of the sliding frame 904 respectively, which is convenient for the reset of the plug 906 and the double fixation of the device. Two springs 909 are arranged inside the placing grooves. Both ends of the two springs 909 are fixedly connected to the corresponding sliding frame 904 and one inner wall of the placing groove respectively.

[0020] In this embodiment, the telescopic spring 5 is sleeved outside the damper 6. Both ends of the telescopic spring 5 and the damper 6 are fixedly connected to the circular plate 12 and the bottom inner wall of the jacket cylinder 3 respectively. The connecting rod 7 slidably penetrates into the inner cylinder 4, and one end of the connecting rod 7 is fixedly connected to the circular plate 12, which is convenient for buffering and shock absorption of the object on the top of the support frame 8. Internal threads 11 are arranged on the inner wall of the jacket cylinder 3, external threads 10 are arranged on the outside of the inner cylinder 4, and the inner cylinder 4 is threadedly connected to the jacket cylinder 3, which is convenient for the installation of the internal thread 11 sleeve and the external thread 10 sleeve. Chute grooves are respectively formed at the tops of the two placing grooves. The two sliding rods 903 slidably penetrate to the tops of the sliding frames 904. Pulling plates 902 are fixedly installed at the tops of the two sliding rods 903. The two pulling plates 902 are respectively slidably installed inside the corresponding chute grooves. Handles 901 are fixedly installed at the tops of the two pulling plates 902, which is convenient for the double fixation of the installation seat 2 and the base 1.

[0021] In this embodiment, during use, when it is necessary to shorten the length of the spring frame, by rotating the inner sleeve 4, it gradually retracts within the outer sleeve 3. The movement of the inner sleeve 4 compresses the telescopic spring 5, and the telescopic spring 5 stores elastic potential energy. At the same time, the overall length of the telescopic spring 5 decreases. During this process, the compression force of the telescopic spring 5 gradually increases, providing a reverse acting force on the inner sleeve 4 to maintain a relatively stable connection between it and the outer sleeve 3, preventing the inner sleeve 4 from extending by itself without external force. When it is necessary to extend the length of the spring frame, rotate the inner sleeve 4 in the reverse direction so that it gradually extends within the outer sleeve 3. The telescopic spring 5 gradually extends under the action of its own elastic force, pushing the inner sleeve 4 to move outward, and the overall length of the spring frame increases. At this time, the tensile force of the telescopic spring 5 gradually increases, providing an outward supporting force for the inner sleeve 4 so that it can stably support the object connected to its extended end. When installing this device, by horizontally pulling up the two groups of handles 901, the two groups of handles 901 drive the corresponding pull plates 902 and slide rods 903 to move upward, causing the two groups of sliding plates 905 to drive the corresponding inserting blocks 906 to disengage from the inside of the mounting seat 2 while driving the compression spring 907. At this time, by horizontally pulling the two groups of handles 901 left and right, the two groups of sliding frames 904 drive the inserting plate 908 on one side to move while compressing the compression spring 909. At this time, place the mounting seat 2 into the inside of the base 1. Then, by releasing the handles 901, under the reset action of the spring 907 and the spring 909, the inserting plate 908 is reinserted into the inside of the base 1, and the inserting block 906 is reinserted into the inside of the mounting seat 2. At this time, it is convenient to effectively install this device and the base 1. The disassembly method is the same.

[0022] The above has introduced in detail a telescopic spring frame provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
