Abstract
Description
Technical Field
[0001] The utility model relates to the field of door control hardware, in particular to a hydraulic door clamp. Background Art
[0002] Door clamps are hardware accessories used to hold glass doors in place and to work with floor springs or floor shafts to ensure proper operation. They are widely used in glass doors and windows, bathroom doors, and shower rooms. Currently, door clamps for glass doors typically come in hinged or spring-loaded styles. Hinged door clamps require manual closing after opening, making them inconvenient. Spring-loaded door clamps, while offering an automatic closing function, lack control over the closing speed.

[0040] Reference below Figures 1-6 A hydraulic door clamp is described in detail with a specific embodiment. It is worth noting that the following description is only for illustrative purposes and is not intended to limit the present invention.
[0041] like Figure 1-Figure 5 As shown, a hydraulic door clamp includes a door clamp body 110 and a base assembly.
[0042] Among them, the door clamp body 110 is provided with an inner cavity (the inner cavity is not shown in the figure), and a through hole is provided at the bottom to communicate with the inner cavity (the through hole is not shown in the figure). The inner cavity is provided with a hydraulic door closing mechanism, and the hydraulic door closing mechanism is provided with a mounting shaft 120 and extends to the outside of the door clamp body 110 through the through hole. The top of the door clamp body 110 is provided with a clamping groove 140 for installing the glass door 130, and the side of the door clamp body 110 is provided with a bolt hole 150 communicating with the clamping groove 140. The bolt hole 150 is provided with a clamping bolt 160 for clamping the glass door 130; the base assembly includes a fixing seat 170 and a sliding seat 180. The four corners of the top surface of the fixing seat 170 are provided with fixing holes 190. A slide groove 200 is provided in the middle of the fixed seat 170 for mounting and moving with the slide seat 180. The slide seat 180 includes an elliptical portion 210 and a long strip portion 220 located on the front and rear sides of the elliptical portion 210. The elliptical portion 210 is provided with an axial hole 230 for sleeve-mounting the mounting shaft 120. The end of the long strip portion 220 is provided with a bevel 240. A first side hole 250, a second side hole 260 and a third side hole 270 are provided on the left and right sides of the fixed seat 170. The first side hole 250 and the second side hole 260 are respectively provided with a first bolt 280 and a second bolt 290 for abutting the left and right sides of the long strip portion 220. The third side hole 270 is provided with a third bolt 300 for abutting the bevel 240. During installation, the glass door 130 is installed within the clamping groove 140 of the door clamp body 110 and then secured with the clamping bolts 160. The fixing base 170 is mounted on the ground through the fixing holes 190 at the four corners of the top surface. It should be noted that holes in the ground must be drilled in advance and installed using expansion bolts. The axis hole 230 in the elliptical portion 210 of the slide 180 is inserted into the mounting axis 120 of the door clamp body 110. The slide 180 is then installed into the slide groove 200. The first and second bolts 280 and 290 abut the left and right sides of the elongated portion 220 to adjust the left and right position of the glass door 130. The third bolt 300 abuts the beveled edge 240 to adjust the front and back position of the glass door 130. The elliptical portion 210 facilitates position adjustment, and the elongated portion 220 also serves as a guide. Due to the beveled edge 240, adjustments only need to be made on the left and right sides of the fixing base 170, not the front and back sides, making position adjustment more convenient. Therefore, the hydraulic door clamp combines the traditional floor spring and door clamp into one with a compact structure. Under the premise of reducing the size, it does not need to dig a hole on the cement floor for installation, and the glass door 130 can be fixed and adjusted. The fixation is more reliable than before and the adjustment is more convenient.
[0043] Specifically, if Figure 3 As shown, the clamping groove 140 is L-shaped and includes a top groove 310 and a side groove 320. In this way, the clamping groove 140 clamps the two sides of the square notch of the glass door 130 through the top groove 310 and the side groove 320, and is fixed reliably. Figure 2As shown, the bottom surface of the top groove 310 is provided with a pad 330, which is used to support and abut the bottom surface of the glass door 130. The pad 330 provided on the top groove 310 can support the bottom surface of the glass door 130, not only allowing for adjustment of the installation height, but also providing a buffering effect, reducing wear on the bottom surface of the glass door 130 by the bottom surface of the slide groove 200. In addition, gaskets 340 are provided on both sides of the clamping groove 140, which are used to abut the sides of the glass door 130. The gaskets 340 on both sides of the clamping groove 140 provide a buffering effect, while also preventing stress concentration on the clamping bolts 160, thereby protecting the glass door 130. Furthermore, bolt holes 150 are provided on one side of the door clamp body 110 and are evenly distributed along the side of the clamping groove 140. This distribution of bolt holes 150 facilitates uniform force application when clamping the glass door 130 and also facilitates installation.
[0044] like Figure 2 As shown, the door clamp body 110 is provided with side covers 350 on both sides, and the side covers 350 are provided with sockets 360 on both sides. The door clamp body 110 is provided with pins 370 at the front and rear ends. The side covers 350 are connected to the pins 370 through the sockets 360 and fixed to the door clamp body 110. The side covers 350 cover both sides of the door clamp body 110, which can shield the bolt holes 150 and clamping bolts 160, thereby providing an aesthetically pleasing and dustproof effect. It is understood that the side of the door clamp body 110 is provided with a buffer sheet 380, which is used to abut against the side covers 350. The buffer sheet 380 provides a filling and cushioning function, which helps protect the door clamp body 110.
[0045] like Figure 5 As shown, the chute 200 comprises a circular groove 390 and a straight groove 400. The elliptical portion 210 is located in the circular groove 390, and the elongated portion 220 is located in the straight groove 400. This arrangement of the chute 200 facilitates its installation with the slide 180. Furthermore, a bottom edge 410 is provided at the bottom of the circular groove 390 to support the sides of the elliptical portion 210. The bottom edge 410 is aligned with the side edges of the straight groove 400. The bottom edge 410 not only supports the elliptical portion 210 but also isolates the slide 180 from the ground, providing protection and facilitating adjustment of the slide 180.
[0046] It is worth mentioning that Figure 4 and Figure 6 As shown, the base assembly also includes an upper cover 420 for covering the front and rear sides of the fixing seat 170 respectively. The inner side of the upper cover 420 is provided with a protrusion 430 for engaging the side of the fixing cover. The upper cover 420 can shield the fixing seat 170 and the sliding seat 180, playing an aesthetic and dustproof effect.
