Description

Technical Field

[0001] This utility model relates to an easy-to-fix roll-up banner base, and in particular to an easy-to-fix roll-up banner base for use in the field of display equipment. Background Technology

[0002] Roll-up banners, also known as poster stands or display stands, are called pull-out banners, pull-out banners, or pull-out rolls in the advertising industry. The main materials for roll-up banner stands are plastic or aluminum alloy, and the posters are made of photo paper.

[0003] To ensure the stability of roll-up banners, a search revealed, for example, a wind-resistant roll-up banner disclosed in patent publication number CN220731136U. This banner includes a support base and a stabilizing component. The support base has casters installed on both sides of its lower end. The stabilizing component is located inside the support base and includes a mounting block, a threaded limiting rod, a water tank, a water inlet, a cap, and a water outlet. The threaded limiting rod is connected inside the mounting block. A water tank is added inside the support base, and a water inlet is located in the middle of the upper end of the support base, with a cap connected to its outer side. A water outlet is added in the middle of the lower end of the support base, and the mounting component is located at the upper end of the support base. The stabilizing component allows for the addition of weight to the otherwise lightweight roll-up banner, reducing the likelihood of it tipping over or shifting due to external forces or even light winds.

[0004] Based on the above search and combined with the existing technology, the existing roll-up banner bases disclosed above only increase their own weight while achieving fixation, making them difficult to move. Therefore, a roll-up banner base that is easy to fix is ​​proposed to improve the above problems. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the method of fixing the base of the roll-up banner by simply adding weight increases its own weight, making it difficult to move at will.

[0006] To solve the above problems, this utility model provides an easy-to-fix roll-up banner base, including a support base with a support frame vertically fixed in the middle of the upper end, a movable wheel installed at the bottom of the support base, a damping component provided on the support base, and a linkage component connected between the damping component and the support frame.

[0007] A pressure handle is rotatably mounted on the support frame. When the pressure handle is pressed, the pressure handle moves the damping component upward through the linkage component.

[0008] An L-shaped clamping slide rod is horizontally slidably installed on the side end of the support base, and a locking bolt that abuts against the L-shaped clamping slide rod is threaded through the side end of the support base.

[0009] In the aforementioned easy-to-fix roll-up banner base, the cooperation of the moving wheels, damping components, linkage components, and pressure handle facilitates the flexible movement and fixation of the base; and the hidden L-shaped clamping slide bar can better fix the base relative to surrounding fixed objects, improving the fixing effect without increasing the weight of the base itself.

[0010] As a further improvement to this application, the damping assembly includes a damping rod, a crossbar, and a tension spring.

[0011] The damping rod slides vertically through the support base, and the horizontal bar is set horizontally on the upper side of the support base and connected to the support base through a tension spring. The top of the damping rod is fixed to the horizontal bar.

[0012] The crossbar runs through the support frame, and the portion of the crossbar located inside the support frame is connected to the linkage assembly.

[0013] As a further improvement to this application, the linkage component includes a pull rod and a connecting rope;

[0014] The tie rod is vertically slidably installed on the inside of the support frame. The bottom end of the tie rod is fixed to the crossbar, and the top end of the tie rod is fixed to the end of the pressure handle located on the inside of the support frame via a connecting rope. The part of the pressure handle located on the outside of the support frame is rotatably connected to the support frame.

[0015] As a further improvement of this application, a tension spring is fixed between the end of the L-shaped clamping slide rod located inside the support base and the support base, and a push-pull handle is fixed to the end of the L-shaped clamping slide rod located outside the support base.

[0016] As a further improvement of this application, the L-shaped clamping slide bar includes a sliding part and a clamping part. The sliding part is slidably connected to the support base, and the clamping part is detachably connected to the end of the sliding part located on the outside of the support base.

[0017] The sliding part is fixed to the tension spring, and the clamping part is fixed to the push-pull handle.

[0018] As a further improvement of this application, a positioning block is fixed to the side end of the clamping part, and a positioning slot for the positioning block to be inserted is provided on the sliding part. A positioning bolt that is threadedly connected to the positioning block is threaded through the side end of the sliding part; this facilitates the adjustment of the position of the clamping part relative to the sliding part according to actual needs, and also facilitates the replacement of the clamping part.

[0019] In summary, pressing the handle moves the damping component upward, allowing the base to be moved flexibly using the casters. Once the base is in the designated location, releasing the handle allows the damping component to automatically fix itself in place using the friction between it and the ground, making it more convenient to use. Furthermore, the concealed L-shaped clamping slide bar can better secure the base to surrounding objects, improving the fixing effect without increasing the weight of the base itself.

Detailed Implementation

[0028] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0029] Implementation method 1:

[0030] Figure 1-6 The figure shows a roll-up banner base that is easy to fix, including a support base 1 with a support frame 2 vertically fixed in the middle of the upper end. The support frame 2 is used to support the display poster, and the support frame 2 is not fully shown in the figure.

[0031] The support base 1 is equipped with casters 3 at its bottom, which facilitates the flexible movement of the base.

[0032] To facilitate quick and easy fixation of the base, a damping assembly is provided on the support base 1. A linkage assembly connects the damping assembly to the support frame 2. Specifically, the damping assembly includes a damping rod 4, a crossbar 5, and a tension spring 6. The damping rod 4 slides vertically through the support base 1. The crossbar 5 is horizontally positioned on the upper side of the support base 1 and connected to the support base 1 via the tension spring 6. The top of the damping rod 4 is fixed to the crossbar 5. The crossbar 5 passes through the support frame 2. The linkage assembly includes a pull rod 7 and a connecting rope 9. The pull rod 7 is vertically slidably installed on the inner side of the support frame 2. The bottom end of the pull rod 7 is fixed to the crossbar 5. The top end of the pull rod 7 is fixed to the end of the pressure handle 8 located inside the support frame 2 via the connecting rope 9. The part of the pressure handle 8 located outside the support frame 2 is rotatably connected to the support frame 2.

[0033] Based on the above structural design, when pressing handle 8, as follows: Figure 6 As shown, the lever 8 moves upward along with the crossbar 5 and the damping rod 4 via the connecting rope 9 and the pull rod 7. Figure 6 The arrow on the lower side of the pressure handle 8 indicates the pressing direction, and the arrow on the pull rod 7 indicates the moving direction of the pull rod 7. When the tension spring 6 is stretched, the damping rod 4 moves away from the ground. At this time, the base can be moved flexibly using the moving wheel 3. After moving to the designated location, the pressure handle 8 can be released, and the return action of the tension spring 6 will cause the crossbar 5 to return to its original position against the ground, thereby automatically fixing the base and making it more convenient to use.

[0034] In addition, to further secure the base, an L-shaped clamping slide bar 10 is horizontally slidably installed on the side end of the support base 1. A locking bolt 11 that abuts against the L-shaped clamping slide bar 10 is threaded through the side end of the support base 1. A tension spring 13 is fixed between the end of the L-shaped clamping slide bar 10 located on the inner side of the support base 1 and the support base 1. A push-pull handle 12 is fixed to the end of the L-shaped clamping slide bar 10 located on the outer side of the support base 1.

[0035] Based on the cooperation of the L-shaped clamping slide bar 10 and locking bolt 11 with the above-mentioned hidden design, the base can be better fixed relative to the surrounding fixed objects, improving the fixing effect without increasing the weight of the base itself, and the L-shaped clamping slide bar 10 is more aesthetically pleasing when stored inside the support base 1.

[0036] The L-shaped clamping slide bar 10 includes a sliding part 101 and a clamping part 102. The sliding part 101 is slidably connected to the support base 1, and the clamping part 102 is detachably connected to the end of the sliding part 101 located outside the support base 1. The sliding part 101 is fixed to the tension spring 13, and the clamping part 102 is fixed to the push-pull handle 12.

[0037] Regarding the detachable connection between the clamping part 102 and the sliding part 101, specifically, a positioning block 103 is fixed to the side end of the clamping part 102, a positioning slot for the positioning block 103 to be inserted into is provided on the sliding part 101, and a positioning bolt 104 that is threadedly connected to the positioning block 103 is threaded through the side end of the sliding part 101.

[0038] The above-mentioned structure allows for easy adjustment of the position of the clamping part 102 relative to the sliding part 101 according to actual needs, and also facilitates the replacement of the clamping part 102.

[0039] Working principle: When movement is required, the operator manually presses the handle 8. The handle 8 moves the crossbar 5 and damping rod 4 upward through the connecting rope 9 and the pull rod 7. The tension spring 6 is stretched, and the damping rod 4 moves away from the ground. At this time, while keeping the handle 8 pressed, the base is pushed and pulled, and the base is moved flexibly using the moving wheels 3. After moving to the designated location, the handle 8 is released, and the return action of the tension spring 6 causes the crossbar 5 and damping rod 4 to return to their original position against the ground, thus automatically fixing the base.

[0040] Pull out the L-shaped clamping slide bar 10, clamp the L-shaped clamping slide bar 10 onto the surrounding fixed object, and tighten the locking bolt 11 to fix the base relative to the surrounding fixed object.

[0041] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
