Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1

[0029] like Figure 1 and Figure 2As shown, a folding screen enclosure includes a side enclosure unit 1, one or more intermediate enclosure units 2 located between two side enclosure units 1 and hinged in sequence, and a bracket 3 fixed to the side enclosure units 1. Each bracket 3 is equipped with a locking component 4, and each of the two side enclosure units 1 is provided with a hook 5. After the folding screen enclosure is folded, the enclosure units are stacked in sequence along the thickness direction. At this time, the locking component 4 on the bracket 3 can be connected to the hook 5 on the side enclosure unit 1 that is away from it.

[0030] The folding screen enclosure described in this utility model consists of multiple enclosure units, which are divided into two types: side enclosure units 1 and middle enclosure units 2. The side enclosure units 1 are located on the outermost side and are used for fixing to the bracket 3. The middle enclosure units 2 are located between the side enclosure units 1 as a connecting structure. The side enclosure units 1, the middle enclosure units 2, and two adjacent middle enclosure units 2 are connected by hinges. When in use, it can be unfolded into a large screen; when stored, it can be folded down to the area of ​​one or two enclosure units. Each enclosure unit includes an outer frame and a covering fabric located between the outer frame. The outer frames of adjacent enclosure units are interconnected.

[0031] The locking assembly 4 is used to connect the bracket 3 at one end and the side enclosure unit 1 at the other end, so that each enclosure unit is tightened together by the locking assembly 4 and will not loosen during transportation. The locking assembly 4 can be set on each of the two brackets 3 to lock all enclosure units from both ends.

[0032] After the folding screen enclosure is folded, the two supports 3 should support all enclosure units on both sides. When the number of middle enclosure units 2 is odd, the folding screen enclosure can be folded into the size of one enclosure unit area, as shown in the figure. When the number of middle enclosure units 2 is even, the folding screen enclosure can be folded into the size of two enclosure units, that is, the two side enclosure units 1 cannot be stacked together.

[0033] In this embodiment, the number of side enclosure units 1 is an odd number.

[0034] Two adjacent enclosure units can rotate 180° relative to each other. In this embodiment, the side enclosure unit 1 and the middle enclosure unit 2, as well as two adjacent middle enclosure units 2, are connected by hinges 6, and the hinges 6 installed on both sides of the same middle enclosure unit 2 are located on opposite end faces. Assuming that the hinge 6 on the left side of the middle enclosure unit 2 is installed on the front, then the hinge 6 on the right side is installed on the back, so that adjacent enclosure units can be folded along a Z-shaped path.

[0035] Similar to that disclosed in patent number CN222314793U, this utility model, for the convenience of moving the folding screen enclosure, preferably has a crossbeam 11 fixed at the bottom of each intermediate enclosure unit 2 and the support 3, and a caster wheel 12 is provided at the bottom of the crossbeam 11. The caster wheel 12 is a caster wheel with a braking function, and the state can be fixed by locking the caster wheel 12 when the folding screen enclosure is in the unfolded state.

[0036] The locking component 4 is a structure that can hook the hook head 5. It can be a simple steel wire rope or a snap hook. The locking component 4 used in this embodiment has the following structure:

[0037] like Figures 3-5 As shown, the locking assembly 4 includes a take-up handle 401, a take-up cord 402, and an elastic pin 403. The take-up handle 401 is rotatably connected to the bracket 3. The outer surface of the take-up handle 401 is provided with a pin hole 4011. The elastic pin 403 is installed on the bracket 3 and can extend into or out of the pin hole 4011. One end of the take-up cord 402 is wrapped around the take-up handle 401, and the other end of the take-up cord 402 is hooked on the hook head 5. When the take-up cord 402 is hooked on the hook head 5, the elastic pin 403 extends into the pin hole 4011. The elastic pin 403 is elastic and abuts against the take-up handle 401 in a free state. It is pulled out when subjected to force. The take-up cord 402 can be a metal wire or a rope, preferably a metal wire with a certain degree of rigidity. The take-up handle 401 can be rotated to tighten or loosen the take-up cord 402.

[0038] After the enclosure units are stacked, pull the elastic pin 403 to disengage it from the pin hole 4011. At this time, rotate the take-up handle 401 and pull the end of the take-up rope 402 to the hook head 5 to connect with the hook head 5. Then rotate the take-up handle 401 in the opposite direction to tighten it. After tightening, the elastic pin 403 is locked in the pin hole 4011, locking the take-up handle 401. When it is necessary to unfold the folding screen enclosure, operate the locking component 4 in the opposite direction.

[0039] In this embodiment, the locking component 4 and the hook 5 work together to help tighten the folding screen enclosure, making the folding screen enclosure fold more compact.

[0040] The take-up handle 401 may, but is not limited to, adopt the following structure:

[0041] like Figure 5As shown, the take-up handle 401 includes a handle portion 4012, a winding portion 4013, and a limiting portion 4014 connected in sequence. The diameter of the winding portion 4013 is smaller than the diameter of the handle portion 4012 and the limiting portion 4014. The handle portion 4012 is the hand-held operating part. It is preferable to provide anti-wear stripes on the surface of the handle portion 4012. The take-up cord 402 is wound around the winding portion 4013. The diameter of the winding portion 4013 is small. The necking design of the winding portion 4013 limits the take-up cord 402 within the winding portion 4013, preventing the take-up cord 402 from moving towards the handle portion 4012 or the limiting portion 4014 or even detaching from the take-up handle 401. The pin hole 4011 is located on the surface of the limiting portion 4014 and is at the same height as the elastic pin 403.

[0042] The flexible pin 403 can, but is not limited to, adopt the following structure:

[0043] like Figures 4-6 As shown, the elastic pin 403 includes a fixed base 4031, a plug-in pin 4032, a plug-in button 4033, and a return spring 4034. The fixed base 4031 is axially fixed to the bracket 3. The axial fixation means that the fixed base 4031 and the bracket 3 are relatively fixed in the extension and retraction direction of the elastic pin 403, and the fixed base 4031 does not perform extension and retraction movement. One end of the plug-in pin 4032 is connected to the plug-in button 4033, and the other end of the plug-in pin 4032 passes through the fixed base 4031. The return spring 4034 abuts against the plug-in pin 4032 and the fixed base 4031. The insertion pin 4032 is a component that extends into the pin hole 4011. The fixed base 4031 is connected to the bracket 3 as a support component for the elastic pin 403. The insertion pin 4032 reciprocates within the fixed base 4031 to achieve the action of extending into or out of the pin hole 4011. The insertion button 4033 is the operating part. The insertion pin 4032 is pulled out by pulling the insertion button 4033. The insertion button 4033 is also preferably provided with anti-wear stripes.

[0044] The fixed base 4031 can be fixed only axially with the bracket 3, meaning that the two can rotate relative to each other. Alternatively, the fixed base 4031 can be absolutely fixed with the bracket 3, meaning that the two cannot produce relative movement.

[0045] Example 2

[0046] Based on Embodiment 1, the outer peripheral surface of the take-up handle 401 is provided with multiple pin holes 4011. At this time, the corresponding pin holes 4011 can be selected to lock the take-up handle 401 according to the different thickness requirements of the enclosure unit.

[0047] Example 3

[0048] In the above embodiments, the plug-in button 4033 and the fixed base 4031 can only contact each other at their end faces. In order to prevent the plug-in pin 4032 from rotating arbitrarily and affecting the ease of operation, this embodiment fixes the plug-in button 4033 and the fixed base 4031 circumferentially based on the above embodiments. The circumferential fixation means that the plug-in button 4033 and the fixed base 4031 will not rotate relative to each other, but can only move relative to each other axially. That is, the plug-in button 4033 can only make translational movements and cannot make rotational movements.

[0049] like Figure 6 As shown, the outer peripheral surface of the fixed base 4031 has a mating groove 7, and the plug-in button 4033 has a claw 8 that extends toward the fixed base 4031 and inserts into the mating groove 7. The claw 8 and the mating groove 7 can achieve circumferential limitation through planar contact.

[0050] Example 4

[0051] Based on the above embodiments, such as Figure 3 and Figure 5 As shown, a pin 4015 is provided on the winding part 4013, and a threading hole 9 is provided at one end of the pin 4015. The coiling rope 402 passes through the threading hole 9. The threading hole 9 has a fixing function for the coiling rope 402 and prevents the coiling rope 402 from loosening.

[0052] Example 5

[0053] Based on the above embodiments, the bracket 3 is provided with an L-shaped mounting plate 10. One side panel of the L-shaped mounting plate 10 is connected to the take-up handle 401, and the other side panel of the L-shaped mounting plate 10 has a fixing hole 1001 for mounting the fixing seat 4031.

[0054] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
