Description

Technical Field

[0001] This utility model relates to the technical field of furniture fixing devices, specifically a screen fixing device. Background Technology

[0002] In modern interior decoration and event setup, foldable items such as folding screens and paper-enclosed folding stools are widely used in various venues due to their ease of storage and flexible arrangement. However, due to the product structure design and the inherent characteristics of the materials, existing folding screens and paper-enclosed folding stools tend to retract after being stretched or unfolded, and the contact area between the two ends and the ground is very small, making them susceptible to deformation and damage under pressure. Furthermore, during use, foldable items such as folding screens and paper-enclosed folding stools also suffer from insecure fixing. In addition, traditional fixing methods often use simple clips, adhesive tape, or binding structures, which are difficult to adapt to different ground environments. When subjected to external impacts or on uneven ground, they are prone to tipping over or shifting, which not only affects the safety of use but may also cause damage to the items, resulting in poor practicality. Utility Model Content

[0003] The purpose of this utility model is to provide a screen fixation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a screen fixer, including a fixing base, a stepped transition portion on one side of the top of the fixing base, a clamping groove at the other end of the fixing base, clamping plates fixedly connected to both sides of the top of the clamping groove, an installation mechanism installed between the two clamping plates, a suction cup mechanism for adsorbing and fixing the object to be installed installed at the bottom of the stepped transition portion, and two counterweight grooves for installing counterweights symmetrically opened at the other end of the bottom of the fixing base.

[0005] As a preferred embodiment of this utility model: the two clamping plates are integrally formed with the fixing base, and a reinforcing connection part is provided at the connection between the clamping plates and the fixing base.

[0006] As a preferred embodiment of the present invention: the installation mechanism includes a hexagonal hole formed on the surface of one of the clamping plates, a hexagonal nut placed inside the hexagonal hole, a countersunk screw threadedly connected to the hexagonal nut, and the head of the countersunk screw placed in a countersunk hole provided on the surface of another clamping plate.

[0007] As a preferred embodiment of this utility model, the surface of the clamping plate is also fixedly connected with reinforcing ribs.

[0008] As a preferred embodiment of this utility model: the suction cup mechanism includes a U-shaped groove formed on the surface of the stepped transition section, a connecting rod is inserted and connected inside the U-shaped groove, the bottom end of the connecting rod is connected to a suction cup placed at the bottom of the fixed base, the top end of the connecting rod is rotatably connected to a cap-shaped handle by a pin, the cap-shaped handle and the pin are inserted and connected inside the U-shaped groove, and a spring is sleeved on the outside of the connecting rod, the two ends of the spring abutting against the bottom of the fixed base and the top of the suction cup, respectively.

[0009] As a preferred embodiment of this utility model, rubber buffer plates are attached to the inner sides of both clamping plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1) This practical screen fixer, through its structural design of clamping grooves, clamping plates, and installation mechanism, can adjust the countersunk screw according to the thickness of the installed object, achieving stable clamping of folding screens and paper enclosed folding stools of different sizes. This prevents the folding screens and paper enclosed folding stools from shrinking back after being stretched or unfolded. The rubber buffer plates on the inner side of the two clamping plates can also protect the surface of the installed object from damage during the clamping process, preventing the ends of the folding screens and paper enclosed folding stools from direct contact with the ground, effectively preventing deformation and damage caused by stress and squeezing. Through the stepped transition part on one side of the top of the fixing base and the suction cup mechanism at the bottom, the suction cup can be squeezed by pressing the cover-shaped handle according to different ground materials, making it firmly attached to the ground, enhancing the overall stability. Even on smooth or uneven ground, it can ensure that the fixer is firmly connected to the ground, preventing the folding screens or paper enclosed folding stools and other installed objects from shifting.

[0012] 2) This practical screen fixer has a counterweight slot at the bottom of the fixing base that can be used to add counterweights according to actual needs, further improving the fixer's anti-tipping ability. Moreover, this fixer is not limited to folding screens and paper enclosed folding stools, which greatly expands the scope of use and effectively improves the practicality and versatility of the product.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-5 This utility model provides a technical solution: a screen fixer, including a fixing base 100, a stepped transition part 110 on one side of the top of the fixing base 100, a clamping groove 120 at the other end of the fixing base 100, clamping plates 130 fixedly connected to both sides of the top of the groove of the clamping groove 120, an installation mechanism 200 installed between the two clamping plates 130, and a suction cup mechanism 300 for adsorbing and fixing the installed object is installed at the bottom of the stepped transition part 110.

[0023] Two counterweight slots 140 for installing counterweights are symmetrically opened at the other end of the bottom of the base 100.

[0024] Specifically, during the setup of indoor exhibitions or temporary event venues, it is necessary to use folding screens (such as...) Figure 4 (as shown) or paper-enclosed folding stools (such as...) Figure 5 When fixed, the clamping groove 120 and the clamping plates 130 on both sides of the top of the groove can be used to clamp the folding screen or paper enclosed folding stool and other installation objects. The installation mechanism 200 between the two clamping plates 130 can adjust the clamping of installation objects of different thicknesses. When placed on the ground, the staff can operate the suction cup mechanism 300 to make it adhere tightly to the ground, so as to achieve non-destructive installation with the ground and other fixed objects, and avoid the phenomenon of shrinkage of the folding screen and paper enclosed folding stool after stretching or unfolding.

[0025] The symmetrical counterweight groove 140 at the other end of the bottom of the fixing base 100 allows for the addition of counterweight blocks when it is necessary to enhance the stability of the fixing device. This can help cope with collisions that may occur in windy environments or when there is frequent pedestrian traffic, ensuring that the fixing device firmly secures the installation to the ground and meets the needs of various complex usage scenarios.

[0026] In this embodiment: the two clamping plates 130 are integrally formed with the fixing base 100, and the connection between the clamping plates 130 and the fixing base 100 is provided with a reinforcing connection part 131.

[0027] Specifically, when the screen fixation device is subjected to large external forces in actual work, the folding screen may generate large lateral forces due to collisions with people. The one-piece molding process of the clamping plate 130 and the fixing seat 100 can effectively ensure that there are no weak connection points between the clamping plate 130 and the fixing seat 100, and the force transmission is more direct and efficient. The reinforced connection part 131 can effectively disperse stress by increasing the local material thickness and optimizing the connection structure, preventing breakage or deformation at the connection point, ensuring that the folding screen or paper enclosed folding stool is always reliably clamped, and ensuring the practicality of the fixation device.

[0028] In this embodiment: the mounting mechanism 200 includes a hexagonal hole 210 formed on the surface of one of the clamping plates 130, a hexagonal nut 220 placed inside the hexagonal hole 210, a countersunk screw 230 threadedly connected to the hexagonal nut 220, and the head of the countersunk screw 230 placed in a countersunk hole 240 provided on the surface of the other clamping plate 130.

[0029] Specifically, when installing folding screens or paper-enclosed folding stools of different thicknesses, the object to be installed is first placed in the clamping groove 120 between two clamping plates 130. A hexagonal nut 220 placed in the hexagonal hole 210 on the surface of one clamping plate 130 cooperates with a countersunk screw 230 passing through the countersunk hole 240 of the other clamping plate 130. By turning the countersunk screw 230 with a screwdriver, since the hexagonal nut 220 cannot be turned in the hexagonal hole 210, the countersunk screw 230 will move towards the clamping plate 130 under the action of the thread, gradually tightening the clamping force on the object to be installed. Whether it is a thinner paper-enclosed folding stool or a thicker wooden folding screen, precise clamping and fixing can be achieved in this way.

[0030] The countersunk screw 230 has its head placed inside the countersunk hole 240, keeping the entire mounting surface flat. This prevents the screw head from protruding and affecting the placement and appearance of the installed object, while also preventing accidental bumps and injuries to personnel, thus improving the safety and convenience of use.

[0031] In this embodiment, a reinforcing rib 132 is also fixedly connected to the surface of the clamping plate 130.

[0032] Specifically, when the object being installed applies pressure to the clamping plate 130, the reinforcing rib 132 can effectively suppress the deformation of the clamping plate 130, prevent it from denting or bending, maintain a reliable clamping force on the object being installed, effectively extend the service life of the clamping plate 130, and also ensure that the fixture can work stably under various working conditions, thus improving the overall reliability and durability.

[0033] In this embodiment: the suction cup mechanism 300 includes a U-shaped groove 310 formed on the surface of the stepped transition portion 110. A connecting rod 320 is inserted and connected inside the U-shaped groove 310. The bottom end of the connecting rod 320 is connected to a suction cup 330 placed at the bottom of the fixed base 100. The top end of the connecting rod 320 is rotatably connected to a cap-shaped handle 340 by a pin. The insertion and connection between the cap-shaped handle 340 and the pin is located inside the U-shaped groove 310. A spring 350 is sleeved on the outside of the connecting rod 320. The two ends of the spring 350 abut against the bottom of the fixed base 100 and the top of the suction cup 330, respectively.

[0034] Specifically, when fixation is required, the operator presses down on the cap-shaped handle 340. The cap-shaped handle 340 moves the connecting rod 320 downwards via a pin, pushing the suction cup 330 into close contact with the ground. During this process, the spring 350 sleeved on the outside of the connecting rod 320 is compressed, generating an upward elastic force, which further enhances the adhesion between the suction cup 330 and the ground. When the cap-shaped handle 340 is released, the elastic force of the spring 350 keeps the suction cup 330 in close contact with the ground, ensuring that the fixture is firmly attached to the ground. When the fixture needs to be removed, the cap-shaped handle 340 is pulled upwards, the spring 350 returns to its original position, and the suction cup 330 separates from the ground. The operation is simple and quick, enabling rapid installation and removal of the fixture in different ground environments.

[0035] Example 2

[0036] Please see Figure 6 The technical feature that distinguishes this embodiment from embodiment 1 is that: in this embodiment, rubber buffer plates 133 are attached to the inner sides of both clamping plates 130.

[0037] Specifically, when clamping and fixing folding screens or paper-enclosed folding stools, the rubber buffer plate 133 first contacts the surface of the object being installed. The rubber material has good elasticity and flexibility, and can deform to a certain extent under the clamping force, evenly distributing the clamping force and preventing the surface of the object from being indented, scratched, or damaged due to excessive local force. Whether it is a fragile paper material or a folding item made of easily damaged wood or plastic, the rubber buffer plate 133 can effectively protect the surface integrity while ensuring the clamping effect. At the same time, the rubber buffer plate 133 can also play a certain anti-slip role, increasing the friction between the object being installed and the clamping plate 130, preventing the object from sliding during use, and further improving the use effect and safety of the fixation device.
