Description

Technical Field

[0001] This utility model relates to the field of three-way water dispenser installation technology, specifically an adjustable limiting bracket and a fixed base for a three-way water dispenser. Background Technology

[0002] A three-way fire hose reel is a type of fire-fighting equipment primarily used to divide the water flow from a fire hose into three outputs, allowing for simultaneous coverage of a larger area or handling of multiple fire points during firefighting. A three-way fire hose reel typically consists of one inlet pipe and three outlet pipes, all connected to the inlet pipe and arranged radially. The three-way fire hose reel requires fixing during use to counteract the reverse impact force of the high-pressure water flow. Currently, due to the large number of manufacturers and specifications of three-way fire hose reels, each specification uses a corresponding fixing bracket. The pressure rod on this bracket, used to limit the hose's movement, cannot be moved, making the brackets non-interchangeable. Developing and processing molds for each type of three-way fire hose reel bracket would significantly increase manufacturing costs. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable limiting bracket and a fixing base for a three-way water separator. The top pressure rod on the limiting bracket can be moved and adjusted, so that the fixing base for the three-way water separator can be used to clamp and fix three-way water separators of different specifications, thereby greatly reducing the processing molds for the fixing base and reducing the processing and manufacturing cost of the fixing base.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an adjustable limiting bracket, including an adjusting base, a movable limiting rod, and a locking positioning buckle. The movable limiting rod is disposed on the adjusting base and can slide freely relative to the adjusting base. The locking positioning buckle is disposed on the movable limiting rod and can realize the movement limitation of the movable limiting rod on the adjusting base.

[0005] Preferably, the adjusting base is in the shape of a long strip, and a plurality of positioning holes are provided on the adjusting base at equal intervals along its length.

[0006] Furthermore, the movable limiting rod includes a sliding locking seat and a pressing rod. The pressing rod is vertically fixed on the upper part of the sliding locking seat. The sliding locking seat is slidably locked on the adjusting base. A through opening is provided on the sliding locking seat. A buckling protrusion is provided at the front of the adjusting base. A first locking groove is reserved between the lower part of the buckling protrusion and the upper plane of the adjusting base.

[0007] Furthermore, the top pressure rod is cylindrical or has a V-shaped cross-section.

[0008] Furthermore, the rear end of the locking and positioning buckle is hinged to the front side of the lower part of the top pressure rod. An L-shaped hook and a limiting pin are arranged sequentially from front to back on the lower part of the locking and positioning buckle. The lower end of the limiting pin can pass through the through hole and be inserted into the corresponding positioning hole. After the lower end of the limiting pin is inserted into the positioning hole, the latch of the L-shaped hook can be engaged in the first locking groove.

[0009] Furthermore, a top support plate is provided at the rear of the through-hole, and a top support lug is provided at the upper rear end of the locking and positioning buckle. The top support lug is made of plastic. When the latch of the L-shaped hook is engaged in the first locking groove, the rear part of the top support lug can press against the front side wall of the top support plate.

[0010] Furthermore, the rear part of the top support ear is distributed in an inclined state with the front higher than the rear.

[0011] Furthermore, a side displacement limiting plate is provided on both the left and right sides of the top plate.

[0012] A fixed base for a three-way water separator includes an adjustable limiting bracket as described above. The fixed base for the three-way water separator also includes a support base.

An adjustable base is provided in each of the positioning grooves.

[0013] Preferably, a support platform is provided on the upper front side of the support base, and an arc-shaped groove is provided on the upper part of the support platform.

[0014] The beneficial effects of this utility model are: The utility model has a simple structure and is convenient to process and manufacture; after the rear end of the three-way water separator is moved and limited by two positioning rods, the two top-pressing rods at the front of the three-way water separator can be adjusted so that the top-pressing rods can be placed in the V-shaped groove between two adjacent water outlet pipes, thereby achieving clamping and fixing of the three-way water separator on the fixed base. By adjusting the position of the top-pressing rods, clamping and fixing of three-way water separators of different specifications can be achieved, thus improving the flexibility of the fixed base. At the same time, the processing mold for the fixed base is greatly reduced, which helps manufacturers reduce the production cost of the fixed base. The manufacturing cost is reduced; the top pressure rod can be moved and positioned on the adjusting base by rotating the locking and positioning buckle, which is convenient to operate; the L-shaped hook is fixed on the buckle protrusion and the top support ear is positioned on the top plate, which facilitates the rotation limit of the locking and positioning buckle, thereby improving the positioning stability of the top pressure rod on the adjusting base, and thus achieving stable clamping of the three-way water separator; the cross-section of the top pressure rod is V-shaped, which matches the V-groove structure between the two water outlet pipes, thereby increasing the contact area between the top pressure rod and the V-groove, and thus improving the support stability of the top pressure rod for the three-way water separator.

Detailed Implementation

[0024] The following will describe specific embodiments and appendices. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] This utility model provides an adjustable limiting bracket (such as...). Figure 1 As shown, the device includes an adjusting base 1, a movable limiting rod 2, and a locking positioning buckle 3. The movable limiting rod 2 is mounted on the adjusting base 1 and can slide freely relative to the adjusting base 1. The locking positioning buckle 3 is mounted on the movable limiting rod 2 and can limit the movement of the movable limiting rod 2 on the adjusting base 1. In practical applications, a three-way water dispenser generally includes one inlet pipe and three outlet pipes. The three outlet pipes are connected to the inlet pipe and are radially distributed. A V-shaped groove is formed between two adjacent outlet pipes. When the front of the three-way water dispenser is clamped and fixed using the aforementioned adjustable limiting bracket, after the adjusting base 1 is fixed, the movable limiting rod 2 is moved to push into the corresponding V-shaped groove. After the movable limiting rod 2 is fixed by the locking positioning buckle 3, the movable limiting rod 2 achieves the forward movement limitation of the three-way water dispenser. Therefore, after the base 1 is positioned, the position of the moving limit rod 2 can be moved to achieve forward positioning of different specifications of three-way water dispensers, which improves the application flexibility of the adjustable limit bracket. At the same time, it can reduce the number of fixed bases used to fix different specifications of three-way water dispensers, thereby helping to reduce the overall processing and manufacturing cost of the fixed bases.

[0026] Based on the above embodiments, the specific implementation of the adjustment base 1 is as follows: the adjustment base 1 is in the shape of a long strip plate, and a plurality of positioning holes 11 are provided on the adjustment base 1 at equal intervals along its length direction. The adjustment base 1 can be made of plastic or steel. In practical applications, the moving limit rod 2 slides along the length direction of the adjustment base 1 for adjustment.

[0027] Based on the above embodiments, the specific implementation of the movable limiting rod 2 is as follows: The movable limiting rod 2 includes a sliding retaining seat 21 and a pressing rod 22. The pressing rod 22 is vertically fixed on the upper part of the sliding retaining seat 21. In actual processing, the sliding retaining seat 21 and the pressing rod 22 can be directly processed into an integral part by casting or machining. The pressing rod 22 can be a cylindrical or V-shaped rod structure. To increase the contact area between the pressing rod 22 and the V-shaped groove, in this specific embodiment, the cross-section of the pressing rod 22 is V-shaped. The sliding mounting base 21 is slidably mounted on the adjusting base 1. Specifically, a T-shaped groove 213 is provided at the bottom of the sliding mounting base 21, and the adjusting base 1 is fitted into the T-shaped groove 213. By utilizing the limiting cooperation between the T-shaped groove 213 and the adjusting base 1, the sliding mounting base 21 can only slide back and forth on the adjusting base 1. A through opening 211 is provided on the sliding mounting base 21, and a buckling protrusion 212 is provided at the front of the adjusting base 1. A first mounting groove 101 is reserved between the lower part of the buckling protrusion 212 and the upper surface of the adjusting base 1.

[0028] Based on the above embodiments, the specific implementation of the locking positioning buckle 3 installed on the moving limiting rod 2 is as follows: the rear end of the locking positioning buckle 3 is hinged to the lower front side of the top pressure rod 22, specifically, making the cross-section of the top pressure rod 22 V-shaped. A hinge shaft 221 is provided on the lower front side of the top pressure rod 22, with both ends of the hinge shaft 221 penetrating the corresponding sidewalls of the top pressure rod 22. A retaining spring 2211 is provided at the end of the hinge shaft 221 to limit the left and right movement of the hinge shaft 221. A sleeve at the rear of the locking positioning buckle 3 is directly sleeved on the hinge shaft 221. The hinge shaft 221 provides rotational support for the locking positioning buckle 3. An L-shaped clip is sequentially provided from front to back on the lower part of the locking positioning buckle 3. The device includes a hook 32 and a limiting pin 31. The lower end of the limiting pin 31 can pass through the through-hole 211 and be inserted into the corresponding positioning hole 11. When the limiting pin 31 is inserted into the corresponding positioning hole 11, the sliding seat 21 is limited to move forward and backward on the adjusting base 1, thereby positioning the limiting rod 22. When the locking buckle 3 is rotated upward, the limiting pin 31 can be pulled out from the corresponding positioning hole 11. After being pulled out, the sliding seat 21 is limited to move forward and backward on the adjusting base 1, allowing subsequent adjustment of the pressing rod 22. After the lower end of the limiting pin 31 is inserted into the positioning hole 11, the latch 321 of the L-shaped hook 32 can be engaged into the first locking groove. In practical applications, the locking protrusion 212 limits the rotation of the latch 321, thus limiting the rotation of the locking positioning buckle 3. This ensures the stable insertion of the limiting pin 31 into the positioning hole 11. Simultaneously, to facilitate the removal of the latch 321 from the first locking groove 101 by rotating the locking positioning buckle 3, the locking positioning buckle 3 can be made of a plastic material with a certain degree of elastic deformation. When the locking positioning buckle 3 is rotated upwards, pulling the front part of the locking positioning buckle 3 upwards causes it to deform and tilt upwards, allowing the latch 321 to be easily removed from the first locking groove 101. Furthermore, when pressing the front part of the locking positioning buckle 3, a certain degree of deformation occurs through its front part during the pressing process. The stretching deformation allows the latch 321 to smoothly engage again into the first locking groove 101. To facilitate the latch 321's smooth engagement into and withdrawal from the first locking groove 101, a first guide slope 2121 is provided on the upper front side of the latching boss 212. The first guide slope 2121 is inclined with a lower front and a higher rear. The guiding effect of the first guide slope 2121 facilitates the latch 321's smooth engagement into the first locking groove 101. A second guide slope 2122 is provided on the lower front side of the latching boss 212. The second guide slope 2122 is inclined with a higher front and a lower rear. The guiding effect of the second guide slope 2122 facilitates the smooth withdrawal of the latch 321 from the first locking groove 101.

[0029] In practical applications, after the latch 321 is successfully engaged in the first locking groove 101, to further improve the locking stability of the locking and positioning buckle 3 and thus improve the insertion stability of the limiting pin 31 in the positioning hole 11, a top plate 214 is provided at the rear of the through opening 211, and a top support ear 33 is provided at the upper rear end of the locking and positioning buckle 3. The top support ear 33 is made of plastic. When the latch 321 of the L-shaped hook 32 is engaged in the first locking groove 101, the rear of the top support ear 33 can press against the front side wall of the top plate 214. By using the pressure of the top plate 214 on the top support ear 33, the locking and positioning buckle 3 can be effectively prevented from rotating, thereby improving the locking stability of the locking and positioning buckle 3. The specific implementation method for achieving contact and abutment with the top support plate 214 is as follows: the rear part of the top support lug 33 is distributed in an inclined state with the front higher and the rear lower. Specifically, an inclined plate 331 is set at the rear part of the top support lug 33. The inclined plate 331 is distributed in an inclined state with the front higher and the rear lower. When the front part of the locking and positioning buckle 3 rotates downward continuously, the rear part of the inclined plate 331 continuously approaches the top support plate 214. When the locking and positioning buckle 3 rotates into place, the rear part of the inclined plate 331 also presses against the top support plate 214, thereby realizing the rotation limit of the locking and positioning buckle 3. In order to improve the rotational stability of the top support lug 33 relative to the top support plate 214, a side displacement limiting plate 2141 is set on both the left and right sides of the top support plate 214, and the top support lug 33 is clamped between the two side displacement limiting plates 2141.

[0030] This utility model also provides a fixing base for a three-way water separator, including an adjustable limiting bracket as described in the above embodiments. The fixing base also includes a support base 4, with four first countersunk through holes 41 around its periphery. In practical applications, countersunk screws are tightened through the corresponding first countersunk through holes 41 into the corresponding threaded holes to fix the support base 4. Two left-right positioning rods 44 are provided on the upper rear side of the support base 4. In practical applications, the three-way water separator is placed on top of the support base 4, with the inlet pipe located between the two positioning rods 44 and the three outlet pipes located in front of the two positioning rods 44. When the three-way water separator is moved backward, the backward movement of the three-way water separator on the support base 4 is limited when the rear wall of the outlet pipe abuts against the corresponding positioning rod 44. Two left-right positioning grooves 43 are provided on the upper front side of the support base 4. An adjustment base 1 is provided in each of the positioning slots 43. To facilitate the installation and fixation of the adjustment base 1 in the positioning slot 43, two second countersunk through holes 12 are provided on the adjustment base 1. Threaded holes corresponding to the second countersunk through holes 12 are provided on the upper side wall of the positioning slot 43. Countersunk screws are tightened through the second countersunk through holes 12 into the corresponding threaded holes to achieve the fixed installation of the adjustment base 1 in the corresponding positioning slot 43. After the three-way water separator is placed on the support base 4, the three-way water separator is first moved so that its rear part abuts against the positioning rod 44 to achieve rearward positioning. Then, the position of the top pressure rod 22 is adjusted so that it presses against the corresponding V-shaped groove on the three-way water separator, thereby achieving the clamping and fixing of the three-way water separator on the support base 4. Because the top pressure rod 22 can be moved back and forth for adjustment and positioning, the support base 4 can achieve clamping and fixing of three-way water separators of different models and specifications.

[0031] After the water inlet pipe of the three-way water dispenser is placed between the two positioning rods 44, in order to improve the stability of the water inlet pipe, a support platform 42 is set on the upper front side of the support base 4, and an arc-shaped groove 421 is set on the upper part of the support platform 42. The arc-shaped groove 421 is in surface contact with the side wall of the water inlet pipe, and its support area for the water inlet pipe is large, thereby providing a stable support for the water inlet pipe.
